Phase 2 Pre-Drywall Inspection — The Last Look Inside the Walls

This is the inspection where the most defects get caught and the most money gets saved — and it's the one most buyers don't even know to ask for. Once drywall goes up, insulation gets blown, and cladding gets installed, access to the framing, the weather-resistant barrier, the structural connections, the rough plumbing, and the electrical rough-in becomes restricted or impossible. Whatever defects were present at drywall hang stay in the wall.

 

If your buyer is under contract on a new construction home that's framed, dried in, and not yet insulated, this is the inspection that matters most.

Why This Inspection Matters

The pre-drywall phase is the last time the bones of the house are fully visible. Once drywall is up, the framing, sheathing, weather-resistant barrier, electrical rough-in, plumbing rough-in inside walls, structural connections, and any duct work routed through wall cavities are no longer accessible. Systems that remain accessible in the attic — HVAC ducts, attic plumbing runs, roof structure — get harder to inspect once insulation is blown and the home is finished. A standard final-walkthrough inspection looks at finishes — paint, flooring, fixtures, appliances. It cannot tell you whether the studs are properly anchored, whether the flashing tape is shingle-lapped, or whether the HVAC penetrations between floors have fire blocking.

​

Production builders run dozens of subcontractor crews through a site in sequence. The framers leave, then the WRB crew, then plumbing, then electrical, then HVAC, then insulation — each one creating holes, penetrations, and modifications that the previous trade didn't anticipate. The municipal inspector typically visits once or twice and signs off based on code minimums. Nobody is verifying that the assembly works as a system. That's what a pre-drywall inspection does.

What We Inspect

We inspect each major system in the same order the trades leave it, mirroring the structure of our written report.

Foundation (Revisited)

The foundation was poured and tensioned weeks earlier, and several foundation-perimeter conditions only become visible after the slab cures and framing goes up. This is also the last window to inspect the foundation perimeter before the builder applies parge coat — a cementitious surface coating that smooths the exposed concrete and conceals everything beneath it. Honeycombing, unsealed post-tension cable anchors, exposed cable chairs, and the early indicators of post-tension cable blowouts are all visible at pre-drywall. After parge coat, they're not.

​

​What we verify:

  • Brick ledge flashing is complete and properly installed at all corners and transitions, so stone or brick veneer cannot bond directly to the slab

  • Post-tension cable anchors are properly sealed with mortar at the foundation perimeter

  • Foundation perimeter is free of embedded form material that would prevent proper parge coat application

  • Honeycombing in the concrete — especially at hurricane straps, wall intersections, and anchor points — is repaired with appropriate materials and methods

  • Driveway and sidewalk reinforcement (rebar chairs, wire mesh) is elevated above grade as required before the pour

​

Common findings:

  • Brick ledge flashing missing or improperly lapped at corners, which will allow veneer to bond to the foundation and crack

  • Honeycombing at hurricane straps and anchor points, creating weak zones in the concrete

  • Post-tension cable anchors left unsealed after stress cut-off, exposing the cables to moisture

  • Embedded form material left in the foundation perimeter

  • Rebar chairs not installed under driveway and sidewalk reinforcing mesh

Exterior Walls

This is the single most defect-rich category in a Phase 2 inspection. The sheathing and weather-resistant barrier (WRB) are the home's primary defense against water intrusion. Every penetration, every seam, every lap is a potential failure point — and once cladding is installed, none of it can be inspected again.

​

​What we verify:

  • Sheathing is properly fastened with no oversunk, underdriven, or missing nails or staples

  • Sheathing is free of holes, tears, surface damage, or unapproved repairs

  • WRB (house wrap or factory-applied structural sheathing) is installed shingle-style with proper overlaps and lap directions

  • Flashing tape is applied to all WRB seams, penetrations, and the bottoms of all rough openings

  • Flashing tape is fully adhered to the wall, not lifted or tented

  • All exterior wall penetrations (HVAC line sets, electrical, plumbing, gas, vents) are flashed and sealed per manufacturer instructions

  • Foam sealant is applied at wall top plates and around penetrations as required

  • Siding starter strips are securely attached prior to cladding installation

​

Common findings:

  • Flashing tape installed in the wrong order — shingle-lapping reversed, allowing water to track behind upper layers

  • Bottoms of rough openings not flashed (the single most common defect we see at this stage)

  • Drywall delivery crews creating large holes in the sheathing for material drop, not repaired before cladding

  • Underdriven staples or oversunk nails in structural sheathing, which fail the manufacturer's fastening spec

  • WRB seams not taped, or tape lifting and not adhered to the wall

  • HVAC line set penetrations, electrical box penetrations, and plumbing penetrations not properly flashed

  • Penetrations through wall top plates not sealed with foam

Wall Framing

The framing is the load path. Anything that compromises how loads transfer from the roof and upper floors down to the foundation needs to be caught before drywall — because drywall conceals it permanently. This is also where we verify the sill plate connection to the foundation, which anchors the entire structure against wind and seismic loads.

​

​What we verify:

  • Wall framing is properly supported by the foundation along its full length, with no sections overhanging the slab edge — overhanging framing has an incomplete load path and is subject to failure over time

  • Bottom sill plate is pressure-treated and properly sealed to the foundation with a continuous foam sealing strip

  • Anchor bolts and anchor straps are placed within the middle third of the bottom plate, correctly spaced, and within the required distance of plate ends

  • All anchor bolts are tight and properly engaged with the sill plate

  • Sill plate is not cracked, split, or damaged at anchor locations

  • Exterior walls are double top-plated with joints properly offset

  • Studs are straight, undamaged, and properly fastened to top and bottom plates

  • Headers, jack studs, and trimmers are correctly installed at all window and door openings

  • Notching and boring of load-bearing walls meets code requirements

  • Corner blocking and nailers are present where needed to support drywall

  • Protector plates are installed for electrical conductors, plumbing, and pest control lines within 1.25" of stud edges

  • No nails are protruding from studs or plates in a way that will damage drywall

​

Common findings:

  • Wall framing overhanging the foundation edge, creating an incomplete load path — parge coat hides the overhang but does not fix it

  • Foam sealing strip improperly installed or missing at the sill plate, breaking the air and moisture seal at the foundation-to-wall transition

  • Anchor bolts placed too close to plate ends or outside the middle third of the plate

  • Loose or cracked sill plates that don't properly hold their anchors

  • Improperly framed load paths (we have found framing above fireplaces that does not actually carry load to the header)

  • Missing corner blocking or nailers, which will cause drywall installation problems

  • Damaged studs and plates from the framing crew

  • Underdriven nails and protruding nails throughout

  • Missing protector plates for electrical and pest control lines

  • Wall sections not properly anchored to the foundation (we have found entire bathroom walls that move under hand pressure)

Floor Framing

On two-story homes, we inspect the floor framing system between floors. On single-story slab-on-grade homes, this section is typically not applicable.

​

​What we verify:

  • Floor joists are properly sized, spaced, and supported

  • Joist hangers are installed at all hanger-required connections, with all fastener holes filled

  • Rim joists and band joists are properly fastened to the sill plate and to the joists

  • Notching and drilling of joists for plumbing and electrical does not exceed allowable limits

  • Subfloor sheathing is properly fastened and free of damage

​

Common findings:

  • Joist hanger fasteners incomplete (missing nails in required hanger holes)

  • Joists notched or drilled beyond allowable limits for plumbing runs

  • Subfloor sheathing with delaminating or moisture-damaged edges

Windows and Doors

Windows and doors are the largest penetrations in the building envelope and the most common location for moisture intrusion. The flashing integration between the window flange, the WRB, and the flashing tape determines whether water that gets behind the cladding drains out — or runs into the wall cavity.

​

​What we verify:

  • Window flanges are caulked, sealed, and properly nailed with fasteners driven to the correct depth

  • Flashing tape at the head, jambs, and sill of each window is installed shingle-style — sill first, jambs over sill, head over jambs

  • Head flashing tape extends beyond the window flange and integrates with the WRB above

  • Exterior doors have head flashing tape installed and properly integrated

  • Exterior garage door trim is tapered at the bottom edges to shed water

  • All glazing is undamaged

​

Common findings:

  • Head flashing tape missing entirely above doors or windows

  • Flashing tape installation reversed — head tape installed before jamb tape, allowing water to track behind

  • Sill flashing not extending past jambs, so water at the sill has nowhere to drain

  • Underdriven fasteners in window nail flanges, preventing the flange from seating against the wall

  • Cracked or damaged glazing from the framing or sheathing crews

  • Garage door trim installed without proper bottom-edge taper

Roof Structure, Roof Covering and Attic

Pre-drywall is the only time the entire roof structure is visible from below. Once insulation is blown in and drywall is hung, rafters, purlins, joists, hangers, and sheathing fasteners disappear. Truss-to-wall connections and engineered hold-downs become impossible to verify.

​

​What we verify:

  • Roof rafters or trusses are properly sized, spaced, and connected to load-bearing walls

  • Truss-to-wall connections are undamaged and properly anchored

  • Trusses are free of damage, warping, splits, or unauthorized field modifications — any cut, drilled hole, or "field repair" voids the truss manufacturer's engineering certification and requires structural engineer evaluation

  • Rafter purlins and support struts are properly attached and bear on load-bearing framing

  • Roof sheathing is properly fastened to rafters, with H-clips between panels as required

  • Roof sheathing is installed perpendicular to rafters at valleys to prevent over-span

  • Ceiling joist hangers are properly installed, aligned, and fully nailed

  • Insulation baffles are installed at each soffit vent location, at the correct height

  • Insulation dams are present between baffles and the wall top plate to prevent wind-washing

  • Roof penetration boots and flashing are installed where roofing is in place

  • If shingles are installed, they are properly seated, fastened, and free of damage

​

​Common findings:

  • Damaged trusses at truss-to-wall connections — sometimes severe enough to require a structural engineer's evaluation

  • Unauthorized field modifications to trusses (cuts, drilled holes, removed members, or improvised repairs) that void the truss certification

  • Rafter purlins not properly attached to rafters or not bearing on load-bearing walls

  • Roof sheathing improperly installed at valleys, creating over-spanned conditions that will sag over time

  • Roof sheathing gapped from the ridge board

  • Joist hangers with missing fasteners (sometimes only one or two of the required nails installed)

  • Joist hangers installed out of alignment with adjacent framing

  • Insulation baffles installed too high in rafter bays, allowing blown-in insulation to block airflow

  • Missing insulation dams, which will cause attic insulation to wash out of the soffit over time

  • Contaminated or moisture-damaged WRB used as insulation dam material

  • Shingles with missing granules, exposed fasteners, or evidence of nail pops (when roofing is already installed)

Electrical

The electrical rough-in is mostly conductors running through studs, joists, and top plates at this stage. The service panel and breakers usually aren't installed yet — that's a final-inspection item. What we can inspect now is whether the rough-in protects the conductors from future nail and screw penetrations, and whether exterior penetrations are sealed.

​

​What we verify:

  • Protector plates (nail plates) are installed at every location where a conductor passes within 1.25" of a stud edge

  • Conductors are not bent beyond the manufacturer's minimum bend radius

  • Staples securing cables are not overdriven, and are not placed where they could damage adjacent conductors

  • Exterior junction boxes are flush with the sheathing, not protruding, so flashing tape can seal them

  • All exterior electrical penetrations have a proper junction box (no exposed conductors)

  • Conductors at penetrations are flashed and sealed per WRB manufacturer instructions

​​​​

Common findings:

  • Missing protector plates at studs and top plates — the single most common electrical rough-in defect

  • Staples driven into or pinching conductors

  • Junction boxes protruding past the WRB, which prevents proper flashing

  • Exterior conductors run without a junction box at the termination

  • Conductors with possible damage from being bent too sharply

Plumbing & Water Heater

The plumbing rough-in is the supply and waste lines inside the walls and under the slab penetrations. We verify the materials, the protection from future nail penetrations, and the readiness for fixture installation.

​

​What we verify:

  • Supply lines (PEX, copper) are properly secured to studs to prevent water hammer

  • Supply lines passing within 1" of stud faces have protector plates installed

  • PEX between conditioned and unconditioned spaces (e.g. between floors) is insulated where required

  • Tub and shower valves are correctly set in the framing so trim plates will sit flush

  • Drain stub-outs are correctly spaced from walls

  • All open supply lines are capped or properly terminated

  • Roof vent stacks are sealed where they pass through the sheathing

  • If the water heater is installed, the TPR valve, expansion tank, and discharge piping are correct

​​​​

Common findings:

  • PEX supply lines installed without protector plates where they are at risk of nail penetration

  • Uninsulated PEX between first and second floors

  • Uncapped supply lines protruding from walls (often where a planned fixture has been moved)

  • Tub valves set too deep or too shallow in the wall framing for the trim to fit properly

  • Roof vent stacks not yet sealed or flashed

Mechanical and Dryer Exhaust Vents

Bathroom fans, range hood, and dryer exhaust ducts all run through the home's framing and terminate at exterior penetrations. The penetrations get flashed at the WRB stage; the duct runs themselves need to be supported, sealed, and made of the correct material.

​

​What we verify:

  • Dryer exhaust duct is rigid metal of the correct diameter, not flex or foil

  • Bathroom and utility exhaust vents terminate to the exterior (not into the attic or soffit)

  • Duct material is appropriate for the use case

  • Duct runs are properly supported and sealed at joints

​​​​

Common findings:

  • Exhaust ducts terminated into the attic or soffit rather than through an exterior wall or roof

  • Dryer duct using flex material in concealed runs (not permitted)

  • Unsupported or sagging duct runs

HVAC

The HVAC rough-in includes the duct system, the air handler (if attic-mounted), and the rough penetrations for the line set and condensate. The outdoor compressor typically is not installed yet. The big-ticket Phase 2 HVAC items are duct support, fire blocking between floors, and the fresh-air makeup duct geometry.​

​

​What we verify:

  • Duct work is properly supported and not crushed, kinked, or sagging

  • Duct work is sealed at the plenum with mastic, not just tape

  • Plenum is properly installed and undamaged

  • Fire blocking is installed at every HVAC duct penetration between the first and second floor

  • Fire-resistant foam sealant is applied at fire-blocked penetrations

  • Fresh-air makeup duct bend radius is within manufacturer specification (tight turns choke the airflow into the unit)

  • Exterior wall penetrations for the line set and makeup air are mastic-sealed and flashed

  • If attic-mounted, the air handler has a decked walkway (minimum 22" wide), 30" of clearance on the control side, and a service light and receptacle planned

  • Line set is properly insulated where it runs through the attic

​​​​

Common findings:

  • Missing fire blocking at HVAC penetrations between floors — a code violation and a fire-safety issue

  • Mastic incomplete or missing at the plenum and at exterior duct terminations

  • Fresh-air makeup duct installed with a tight-radius turn that will restrict airflow into the unit

  • Line set penetration not flashed or sealed at the exterior wall

  • Duct work crushed or pinched where it passes through framing

Gas Piping

If the home has gas service, the rough-in is typically black iron pipe with concealed fittings, run from the meter location to each gas appliance stub-out.

​

​What we verify:

  • Gas piping is of appropriate material (black iron, CSST where permitted)

  • Concealed fittings are of appropriate material for in-wall use

  • Gas supply entry is above grade

  • Piping in walls is protected against nail and screw penetration with protector plates

  • Piping is properly supported and installed without unauthorized notching of framing members

  • Stub-outs at each appliance location are capped and labeled

​​​​

Common findings:

  • Missing protector plates at gas line penetrations through studs

  • Unauthorized fittings in concealed locations

  • Improperly supported piping runs

Realtor Advice & Strategy

For Buyer Agents

  • The "Sealed Behind Drywall" Script: This is the inspection where we catch the things that get hidden forever once drywall goes up. Plan for a real list — that's the purpose. The list is your leverage to get it fixed now, while it's still cheap.

  • The "Code vs. Quality" Script: The builder's municipal inspector is checking for code compliance on a specific set of items. Our inspector is checking whether the assembly actually works as a system — flashing tape lapped the right direction, fire blocking in place, anchor bolts in the middle third of the plate. Those aren't always the same thing.

  • The "48 Hours to Catch It" Script: You have a short window between framing complete and drywall hanging — sometimes only 48 to 72 hours. The earlier we schedule, the more options you have for getting items corrected before they're sealed inside the wall.

  • The "Get It in Writing" Script: Request the inspection report be addressed to your buyer, with a copy to the builder's superintendent or warranty manager. This creates a documented record before drywall goes up — and it's the record your buyer will reference if anything comes up in their one-year, two-year, or ten-year warranty period.

Coordinating with the Builder

  • Texas production builders typically do not require the buyer or the buyer's representative to be on-site during the inspection, but we coordinate the visit directly with the builder or with the buyer's agent at booking.

  • Builders typically prefer 24-48 hours notice. Call us the day your superintendent says framing is wrapping up — not the day drywall is scheduled.

Handling Builder Pushback

Common objections from builder reps, and how to respond.

​

"The municipal inspector already passed it." The municipal inspector checks for code minimums on a specific set of items, on a specific date, in a specific window of the build. A pre-drywall inspection checks the assembly as a system, after every trade has finished, the day before drywall hangs. The two inspections do different things, and finding defects after a municipal sign-off is not unusual — it is normal.

"We have our own quality control process." Most builders do, and most builder QC processes are excellent. They are also internal. An independent third-party inspection gives your buyer documentation that does not depend on the builder's internal records, which matters if a warranty claim arises three or five years from now.

"Your inspector is being too picky." Every item on the report is referenced to the manufacturer's installation instructions, the relevant code, or the structural engineer's specifications. If a finding is genuinely outside scope, we will say so. If it is on the report, it is because the installation does not match the spec the builder is contractually required to meet.

"We will get to it before drywall." This is often true, and we are happy to verify completion at a follow-up. What we will not do is omit items from the written report on the promise that they will be fixed. The written record is what your buyer pays for.

"The trades are coming back tomorrow to finish that." Possibly — but the report reflects the condition at the time of inspection. If the trades return and complete the work, that is captured in the Phase 3 final inspection.

Recommended Ancillary Services

  • Phase 3 Final Inspection: Verifies completion of pre-drywall punch list items and inspects everything that wasn't accessible at Phase 2 (finishes, fixtures, appliances, energized electrical, gas service, HVAC operation)

  • Sewer scope: Verifies the lateral from the home to the city tap; pre-drywall is the cheapest time to catch a damaged lateral

  • Thermal imaging at Phase 3: Verifies insulation coverage after drywall is up, catching gaps that visual inspection can miss

What Comes Next

After pre-drywall, the home is insulated, drywalled, finished, painted, and the systems are energized. The Phase 3 Final Inspection verifies that the pre-drywall punch list was completed and inspects every system that wasn't accessible or active during Phase 2 — the energized electrical service, the operating HVAC, the installed appliances, the finished plumbing, and all interior and exterior finishes.

​

If your buyer is doing all three phases (pre-pour, pre-drywall, final), the Phase 3 inspection closes the loop. If they are doing only one of the three, this is the one.

If You're a Buyer Reading This...

You are mid-build, and you are in the most important window of the entire construction process. Here is what to do:

  • Schedule immediately. The window between framing complete and drywall hang is short. Some builders only give 48-72 hours. Call us the day your superintendent says framing is wrapping up — not the day drywall is scheduled.

  • Be on-site if you can. Most builders allow buyers to attend with their inspector. You will learn more about your home in two hours at pre-drywall than in any other single event in the construction process.

  • Don't accept "we'll fix it" verbally. Every item should be on the written report, and every item should be verified complete at your Phase 3 final inspection.

  • Use the report. Send it to your builder's warranty manager in writing, with a request for written confirmation of repairs. This is your record if anything comes up in your one-year, two-year, or ten-year warranty period.
