A pre-drywall inspection is an independent evaluation of a new home after the framing, roof, windows, rough plumbing, rough electrical, and HVAC ductwork are installed, but before insulation and drywall cover them up. It is the only point in the life of a house when the structure and every rough-in can be seen in full. Once the drywall goes on, those systems are hidden for good, and any mistake behind the wall becomes your problem to discover later.
Insight Home Inspection Services, LLC performs pre-drywall and phase inspections on new construction in Nashville, Knoxville, and Chattanooga, Tennessee, and Atlanta, Georgia. Founded in 2014 with over 5,000 inspections completed, Insight has inspected nearly 100 new-construction homes across Tennessee since 2025 alone, and we have not yet seen one with zero findings.
Why the Builder's Inspections Are Not Enough
New-construction buyers often assume the home has already been checked. It has, but not on your behalf.
- The municipal framing inspection is a minimum-code spot check. Inspectors in fast-growing counties visit dozens of sites a day, spend minutes at each, and look for code violations, not workmanship, durability, or the details that cause callbacks.
- The builder's superintendent manages the schedule and the subcontractors. Their job is to keep the build on time. Even a conscientious super cannot catch everything a framing crew, a plumber, and an electrician left behind across a dozen active lots.
- The builder's pre-drywall walkthrough is a courtesy tour. It is not an inspection, and the person leading it works for the builder.
A pre-drywall inspection from Insight puts a licensed inspector who works only for you on the site, with a camera, before the walls close.
What a Pre-Drywall Inspection Covers
Our inspector walks every room, the attic space, the garage, and the crawlspace or slab perimeter, and documents the condition of:
Foundation and Structure
- Anchor bolts, hold-downs, and sill plate contact
- Slab cracks, crawlspace piers, and girder bearing
- Foundation waterproofing and damp-proofing where still visible
- Rough grading and drainage around the foundation
Framing
- Bearing walls, headers, and point loads carried to the foundation
- Notched, bored, or over-cut studs, joists, and top plates
- Missing or under-nailed joist hangers and metal connectors
- Field-modified or damaged roof trusses, which void the truss engineer's design
- Fire blocking, draft stopping, and blocking for future fixtures
- Squash blocks and load paths at multi-story stacking
- Moisture-damaged or mold-stained lumber from exposure during the build
Exterior Envelope
- Window and door flashing sequence (one of the most common and most expensive errors in new homes)
- House wrap laps, seams, and penetrations
- Roof decking, underlayment, and flashing details visible from the attic
- Deck ledger attachment and flashing
Rough Plumbing
- Supply line routing, support, and protection
- Drain, waste, and vent slope, support, and venting
- Nail plates where pipes pass through studs and plates
- Tub and shower pan installation and drain connections
- Water heater, hose bib, and condensate rough-ins
Rough Electrical
- Box placement and fill, cable support and protection
- Nail plates where cables pass through framing
- Panel location, clearances, and service entrance
- Bonding and grounding provisions
- Missing boxes for required outlets, lights, and switches
HVAC Rough-In
- Duct routing, support, sealing, and crushed or kinked flex duct
- Return-air pathways and sizing
- Condensate drain and secondary drain pan provisions
- Bath and dryer exhaust terminating outdoors, not in the attic
Every defect is photographed and located by room so the builder's superintendent can walk directly to it.
Common Pre-Drywall Findings in Tennessee New Builds
Across our Tennessee markets, the same problems show up again and again at the pre-drywall stage:
- Roof trusses cut or notched by a trade to make room for a duct or vent stack
- Joist hangers with half the nail holes empty
- Missing nail plates over plumbing and wiring in stud walls
- Window flashing tape installed in the wrong order, sending water behind the house wrap instead of over it
- Drain lines with no slope or back-pitched toward the fixture
- Flex duct crushed between framing or run with sharp bends that choke airflow
- Bath exhaust fans venting into the attic
- Fire blocking missing at soffits, chases, and between floors
- Studs bored out so far that the wall is structurally compromised
Each of these takes minutes to fix while the framing is exposed. After drywall, the same repair means opening finished walls, and many are never found at all until they fail.
When to Schedule
The pre-drywall window is short, often only a day or two between the final rough-in trade finishing and the insulation crew arriving. To hit it:
1. Ask your builder early for the projected pre-drywall date and confirm that a third-party inspection is permitted. Most builder contracts allow it; some ask for the inspector's license and insurance information, which Insight provides on request.
2. Call Insight as soon as you have a date, even if it is tentative. We will hold the slot and adjust as the schedule moves.
3. Inspect before insulation, not after. Once batts are in the walls, wiring, plumbing, and nail plates are hidden again. If the builder has already insulated, tell us and we will inspect what remains visible.
The Full New-Construction Inspection Program
A pre-drywall inspection is the first of three inspections we recommend for every new build. Skipping any one of them leaves a gap.
1. Pre-drywall inspection, covered on this page, while the structure and rough-ins are exposed.
2. Final inspection before closing, a full pre-purchase inspection of the completed home: 400+ items, every system operated, and a photo-documented report within 24 hours, delivered far enough ahead of closing for the builder to make repairs.
3. 11-month warranty inspection, a complete re-inspection in the last month of the builder's one-year workmanship warranty, so everything that settled, cracked, or failed in year one is documented and submitted as a warranty claim instead of paid for out of pocket.

Other Construction Phases
Pre-drywall is the most valuable phase inspection, but it is not the only one. Insight also performs:
- Foundation / pre-pour inspections of footings, forms, rebar, vapor barrier, and plumbing rough-ins in the slab before concrete is placed.
- Framing-only inspections when the rough-in trades have not yet started.
- Re-inspections to verify the builder corrected the items from a previous phase report.
Tell us where the build stands and we will recommend the right visit.
Pre-Drywall Inspection Cost
Pre-drywall and phase inspections start at $250. The final price depends on the square footage of the home and which phase of construction it is in. A pre-drywall inspection is a standalone site visit and is priced separately from the full home inspection at completion, which runs $500 to $1,000+ by square footage.
Measured against the cost of opening finished walls to correct a framing or plumbing defect, or living with one you never find, it is the least expensive inspection you will ever buy on a new home.
Frequently Asked Questions
What is a pre-drywall inspection?
A pre-drywall inspection is an independent inspection of a new home after framing, rough plumbing, rough electrical, and HVAC ductwork are installed but before insulation and drywall cover them. It is the only opportunity to evaluate the structure and rough-in work while it is fully visible and inexpensive to correct.
How long does a pre-drywall inspection take?
Most pre-drywall inspections take 1 to 2 hours on site, depending on the size of the home. The photo-documented report is delivered within 24 hours so you can forward it to your builder before insulation begins.
Can my builder refuse a pre-drywall inspection?
Most production and custom builders in Tennessee and Georgia permit third-party inspections; it is commonly written into the purchase agreement. Some require advance notice, a scheduled time, or the inspector's license and insurance information. Check your contract and give the builder as much notice as possible. Insight provides any documentation the builder requests.
What happens if the inspection finds problems?
You send the report to your builder's superintendent, who has the trades correct the items before drywall. Because the work is still exposed, most fixes take minutes. Insight can return for a re-inspection to confirm the corrections were made.
Is a pre-drywall inspection required?
No. It is optional and paid for by the buyer. It is also the single best value in new-construction inspections, because it catches the category of defects that no later inspection can see.
Does the county's framing inspection cover the same things?
No. The municipal framing inspection checks for minimum code compliance in a brief visit. It does not evaluate workmanship, flashing details, duct quality, moisture damage, or dozens of other items that a private inspection documents, and the county inspector does not report to you.
Do I still need a final inspection if I had a pre-drywall inspection?
Yes. The pre-drywall inspection covers what is behind the walls. The final inspection before closing tests the completed home: roof, exterior, appliances, fixtures, HVAC operation, electrical function, grading, and everything installed after drywall. They cover different things and both matter.
