When you sign a contract on a brand-new home, the builder hands over a long list of warranty terms, reassurances about quality control, and a closing date. None of that replaces an independent home inspection. Walk through any subdivision in Bucks County, Montgomery County, or Philadelphia, and you can find newly built homes with missing flashing, miswired outlets, drainage issues, and HVAC ductwork that does not match the plans. The builder did not cut corners on purpose. New construction involves dozens of trades, tight schedules, and inspectors from the township who are checking for code, not for buyer protection.
We have inspected new builds across the Delaware Valley for more than thirty years, and the pattern is consistent. Buyers who skip the independent inspection often find expensive problems after closing, when the builder’s responsiveness drops. Buyers who bring in their own inspector usually save more than the inspection cost on the very first item flagged.
Why Do New Builds Still Need A Home Inspection?
A new home is not a perfect home. It is a home that was finished quickly enough to close on the contracted date. Even on a high-quality build, you should expect punch-list items, settling cracks, paint flaws, and minor mechanical issues. The serious risk is the items that are hidden behind drywall, behind cabinets, in attics, in crawlspaces, and on rooftops where the buyer simply cannot see them.
Township inspections are not buyer inspections
Township and municipal inspectors verify code compliance: permits, structural minimums, electrical safety, plumbing fixtures, and HVAC equipment ratings. They do not check whether the bathroom exhaust vents into the attic instead of the roof. They do not check whether the attic insulation actually meets the depth shown on the plan. They do not test every receptacle, run every appliance, or document the condition of the roof flashing in detail. Your inspector does.
Builder QC and your own QC are not the same thing
A builder’s quality-control walkthrough exists to protect the builder. The inspector you hire works only for you. They have no relationship with the framing crew, the HVAC sub, the roofer, or the electrician. They are looking for omissions and defects with the same care they would apply to a 70-year-old farmhouse. That independence matters most when an item is debatable, and the builder needs a third-party report to act.
In our experience inspecting new builds in Bucks County and Montgomery County, the most common findings include: missing kickout flashing on roof-to-wall transitions, attic insulation depths well below the plan spec, GFCI receptacles wired to the wrong circuits, condensate lines draining into structural cavities, and grading that pitches water back toward the foundation. Each one is fixable. None of them are obvious to a non-inspector during a thirty-minute final walkthrough.
What Is A Pre-Drywall Inspection And When Do You Schedule It?
A pre-drywall inspection, sometimes called a preconcealment inspection, happens after framing, electrical, plumbing, and HVAC rough-ins are complete, but before insulation and drywall go up. It is the only chance you will ever have to look behind the walls of your own home.
The timing matters. Schedule it after the township rough inspections have passed and after the major rough trades have wrapped, but before insulation and drywall delivery. Most builders move from rough-in to drywall within a few days, so coordinate the date with your sales rep or construction manager as soon as you have a closing target. We typically need 24 to 48 hours notice to fit a new build into the schedule during peak spring and summer construction.
What we look at during pre-drywall
We document framing, including engineered lumber sizing, header dimensions, beam pockets, fire-blocking, sheathing nailing patterns, and any cuts or notches that compromise structural members. We trace electrical runs and verify boxes are properly secured, supply lines are protected from nail strikes, and circuit routing matches the panel schedule. We follow plumbing supply, waste, and vent lines for proper slope, support, and clearances. We inspect HVAC ductwork for sealed connections, correct sizing, and routing that will not create dead spots once the home is closed up.
Why this is the highest-value inspection
After drywall goes up, every issue behind the wall becomes a wall-opening repair instead of a fifteen-minute fix. A loose duct connection that is found pre-drywall is corrected in minutes. The same defect found three years later might mean a drywall demo, an HVAC company callout, and a four-figure invoice. Buyers who add a pre-drywall inspection to their final inspection at closing typically spend a few hundred dollars extra and walk away with a tighter, better-built home. See our preconcealment inspection page for the full scope.
What Do New Construction Inspectors Find?
The myth around new builds is that defects are minor cosmetic issues. The reality is that new construction defects fall into the same categories as resale defects: structural, mechanical, electrical, plumbing, exterior envelope, and grading. The only thing that is actually new is that the homeowner has a brief warranty window to push for free repairs before the builder transitions out of the project.
Common findings on a final inspection
On the final walkthrough inspection, the one we do a few days before closing, we routinely find missing kickout flashing where the roof meets a sidewall, gaps around penetrations through the building envelope, sloppy caulking around tubs and showers, refrigerator water lines unsecured behind cabinets, and HVAC airflow that is severely unbalanced between rooms. We test every receptacle and switch. We run every appliance through a full cycle. We open every window and door and check operation, latches, and weatherstripping. For a broader look at the standard scope, see what home inspectors actually look for.
Site and grading issues
Grading issues are some of the most expensive problems on new construction in Southeastern Pennsylvania, where clay soils and steep yards meet basements and slabs. We document final grade slope, downspout extensions, sump-pump discharge routing, window wells, and any low spots that will collect water. A regraded lot a year after closing can run several thousand dollars when the builder is no longer responsive. A note on the inspection report before closing usually gets it fixed at no cost.
Documentation matters more than you think
On a resale, your inspection report is mostly for your own decision-making. On a new build, the report is the document you hand to the builder’s warranty department. A clear, photo-rich report with specific code or specification references makes it harder for the warranty manager to push back. We write reports specifically with that conversation in mind.
How Does The Builder Warranty Process Work With Inspection Findings?
Most production and semi-custom builders provide a one-year limited warranty on workmanship and materials, longer limited warranties on mechanical systems, and a structural warranty (often ten years) backed by a third party. The exact terms vary, so read your contract before closing.
Use the inspection report as your warranty roadmap
The most common buyer mistake on new builds is letting the warranty year expire without a thorough year-end review. Many issues, including drywall cracks, sticking doors, grout separation, and HVAC balance problems, only show up after a full season of seasonal cycling. We recommend an eleven-month inspection in addition to your pre-closing inspection. The report from the eleven-month visit becomes the punch list you submit to the warranty department before the warranty window closes.
How to handle pushback
Builders sometimes argue that an item is within tolerance or normal settling. That can be legitimate. It can also be a way to delay until the warranty expires. A specific, photographed finding with measurements and references to industry standards is harder to dismiss. If the issue is structural or affects safety, an independent third-party report carries more weight than a homeowner email. If a builder remains unresponsive, an expert witness inspection (see our expert witness inspection page) provides documentation suitable for legal proceedings.
What we do not recommend
Do not skip the final inspection because the builder offered a free walkthrough with their own QC team. Do not waive the inspection contingency on a new build because the township already inspected. Do not rely on a video walkthrough or photos from your real estate agent in lieu of an in-person inspection. New construction has more moving parts than a typical resale, and every unverified system is a potential warranty claim later.
If you want a clear scope of what we cover, the home inspection page walks through our standard report. For a new-build scope, we add the pre-drywall and eleven-month visits to that baseline.
Frequently Asked Questions
Can the builder refuse to let you bring an inspector?
Most builders allow buyer inspections, but they may require advance notice and a specific time window. A few builders try to discourage independent inspections through contract language. Read your purchase agreement carefully before signing, and push back on any clause that prevents your inspector from accessing the home. If a builder will not allow an independent inspection, that is itself a warning sign.
How many inspections should you get on a new build?
For most buyers in Bucks County, Montgomery County, and Philadelphia, three inspections cover the lifecycle: a pre-drywall inspection after rough-ins, a final pre-closing inspection a few days before settlement, and an eleven-month warranty inspection before the one-year warranty expires.
When is the final inspection on new construction?
We schedule the final inspection five to ten business days before closing. That gives the builder time to address findings before settlement and gives your real estate agent time to negotiate any issues that the builder will not correct.
Does your builder’s home inspection count?
No. The builder’s quality-control walk and the township code inspection both serve the builder, not the buyer. Neither replaces an independent inspection by an inspector you hired.
What happens if the inspector finds issues after closing?
Issues found after closing fall under the builder warranty. Submit them in writing to the warranty department with the inspection report, photos, and a clear description. Keep the email thread, and request a written response with a timeline. If the builder is unresponsive on a structural or safety item, an independent inspection report adds the leverage you need.
Are new construction inspections worth the cost?
Yes. New-build buyers usually save the cost of the inspection on the first or second item we flag, most often a flashing detail, an HVAC issue, or a grading problem that would otherwise become an out-of-pocket repair after the warranty expires.
