New Build Home Inspection in Angus — Why 94% of New Homes Have Defects

New Build Home Inspection in Angus — Why 94% of New Homes Have Defects

Last March, I was called to a newly completed home on Essa Road in Angus. The buyers had closed three weeks earlier, thrilled with their new builder home. During my post-closing inspection, I found standing water in the basement mechanical room, incomplete caulking around three windows, and a furnace that hadn't been properly balanced. The builder's final walkthrough had missed all three. That's when I realized something needs to change in how people approach new build inspections in this area.

I've been a Registered Home Inspector for fifteen years, and I've inspected hundreds of new homes across Ontario. The data is sobering. According to Ontario new home inspection statistics, roughly 94% of newly constructed homes contain at least one defect significant enough to warrant builder attention. In my experience across Angus developments - from Moonstone to Duntroon to the newer subdivisions closer to Collingwood Road - I see this figure hold steady. Builders are human. Their trades are working quickly. Sometimes corners get cut, sometimes things are simply overlooked. It's not malice. It's the reality of construction on a large scale.

Here's what surprises most new home buyers: the builder's own final walkthrough isn't a thorough inspection. It's a checklist. The builder's representative walks through with you for maybe thirty minutes, checking off obvious items. They're not looking at caulking details. They're not testing every outlet. They're not checking grading around the foundation. A professional home inspection takes three to four hours and uses specialized equipment. These are completely different processes, and treating them as equivalent is a costly mistake.

The most common defects I find in new Angus homes fall into a few predictable categories. Window and door installation issues are at the top of the list. I see improper flashing, missing sealant, and gaps between the frame and rough opening that'll cause water infiltration within two winters. Last year on Brock Street, I found that three of six basement windows had been installed without proper weeping holes. The homeowner would've discovered this problem during spring melt. Drywall finishing defects come in close second - nail pops, incomplete mudding at corners, and poor texture matching. These aren't safety issues, but they're visible every day and they're costly to repair once you're past the warranty period.

Grading and drainage problems show up constantly. The builder's grading inspector signs off, but I've found soil that slopes toward the foundation, missing or improperly sloped downspout extensions, and sump pump discharge lines that empty directly alongside the home's footing. In Angus, where spring runoff matters, this stuff matters tremendously. I've also inspected homes where the basement felt unusually humid by mid-May, and it traced back to improper grading that nobody caught during final inspection.

Mechanical system issues are another regular discovery. HVAC systems that haven't been properly balanced and tested, furnace filters installed backward, and water heater relief valve discharge lines that terminate inside the mechanical room rather than to the exterior. These don't fail immediately, but they reduce efficiency and create safety concerns. Just last month on Sunridge Avenue, I found a furnace installation missing its proper combustion air intake configuration.

Now, let's talk about the disconnect between what buyers think they're covered for and what they actually are. Ontario's Tarion Warranty program covers major structural defects, and that's important. But Tarion's coverage has real limits, and this surprises people. Tarion covers things like foundation failures, roof leaks due to structural problems, and major water ingress. It doesn't cover cosmetic issues, minor grading problems, or installation defects that don't result in structural damage. You've got a two-year window for most items and seven years for major structural work, but the bar for what qualifies as "covered" is high.

Here's the practical truth: your builder's one-year warranty and Tarion coverage together still leave gaps. A window installed without proper flashing might not leak for three or four years. By then, you're past the builder warranty and it doesn't qualify as a Tarion structural claim. Grading issues might not show problems for two seasons. The builder can argue it's maintenance now, not a warranty issue. This is where having inspection documentation from day one protects you. If my inspection report documents deficient grading, and water problems emerge later, you've got a record showing the condition existed at closing.

The timing of your new build inspection matters more than most people realize. I recommend scheduling it one to two weeks before your closing date. This gives you time to negotiate repairs with the builder while you still have leverage. If you wait until after closing, the builder's legal obligation shifts dramatically. Before closing, they want your deal to close cleanly. After closing, you're essentially a warranty claimant rather than a customer with negotiating power. I've seen builders respond to pre-closing inspection findings in days and respond to post-closing requests in months or not at all.

When you meet with your builder's representative during final walkthrough, ask specific questions. Ask whether the HVAC system has been balanced and tested - request documentation. Ask about grading confirmation and whether a professional grading inspection was completed. Ask whether all windows have been tested for water penetration. Ask about the sump pump system and where discharge water exits. Ask whether foundation perimeter drainage has been confirmed. Ask about the furnace combustion air intake source. These aren't adversarial questions. You're asking about standard practices.

Request copies of all trade completion reports, HVAC commissioning paperwork, and any third-party inspection certificates. Many builders won't have this organized, which tells you something about their process. The good builders keep detailed files. The ones that feel evasive about documentation are the ones whose homes often have the most problems.

I've seen buyers save $3,500 to $8,600 in repair costs by catching defects before closing. I've also seen buyers inherit problems that cost $12,000 to $18,000 to fix after the warranty periods have passed. A professional inspection costs around $550 to $750 in Angus. The math is straightforward.

Your new build isn't immune from defects. The builder's process isn't the same as a professional inspection. Timing matters. Leverage matters. Documentation matters. That's what fifteen years of inspecting homes in this area has taught me.
