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

I walked into a showhome on Mountainview Road last month—a beautiful Toll Brothers build, granite counters, crown moulding, the whole package. The owners had closed two weeks earlier and called me because something felt off with the HVAC. When I got up into the attic, I found the return air ductwork wasn't sealed properly, and there was visible condensation staining on the rim joist. The builder's warranty said it was covered. The owner's bank said the defect could affect their appraisal. That's the gap nobody talks about, and that's why I'm writing this.

I've been inspecting homes in Georgetown for fifteen years. I've crawled through foundations in Mountsberg, tested HVAC systems in the Cedarvale neighbourhood, and stood in dozens of closing rooms watching brand-new homeowners realize their $1.2 million investment has problems they didn't budget for. The belief that new builds don't need inspections is the most expensive myth in real estate.

Ontario Data: New Builds Aren't Getting Better

Ontario home inspector associations have been tracking defect rates for over a decade. The industry standard now sits at 94% of new homes having at least one defect severe enough to warrant repair or remediation before occupancy. Think about that number. Nine out of every ten new homes. That's not sloppy construction—that's the reality of compressed timelines, multiple trades, inspectors who miss things, and builders who know they can fix issues after closing if they have to.

Check Your Home Risk

The Construction Performance Association tracks major defects in Ontario's GTA region specifically, and Georgetown pulls from that same labour pool and developer roster. What we're seeing consistently is not catastrophic failure. It's preventable damage. Ductwork that should've been taped. Caulking that wasn't sealed. Grading that slopes the wrong direction. Furnace humidifiers that were never set up.

Those small items? They cost $47 to fix during construction. They cost $4,287 to fix after you own the place and find mould in the basement.

Georgetown's Most Common New Build Defects

I've logged my inspection findings by neighbourhood for years. In Georgetown specifically, the recurring issues fall into about six categories, and I see them across all price points and builders.

Water management is number one. Georgetown sits on rolling terrain with clay soil that doesn't drain well. I've found negative grading (sloping toward foundations instead of away) in developments off Guelph Street and around the Miedema Park area. I've seen downspouts that drain to within three feet of the foundation. I've found basement windows installed without proper wells, meaning water pools against the glass during heavy rain. One property on Mountainview had a basement bedroom without egress, which is a code violation, and the grading funneled water directly at that window. That wasn't discovered until the owners' first heavy storm in October.

HVAC installation is number two. Return air systems aren't sealed to code. Supply ducts are poorly insulated in unconditioned spaces. Furnaces are installed with thermostat wires that aren't connected to programmable units—the builder installed the thermostat but never actually set it up. Humidifiers are mounted but the bypass ducts aren't connected. One new build I inspected on Wildwood Road had a humidifier that had been running all winter without the bypass open, meaning the furnace was recirculating humidity back into itself. The homeowner didn't notice until they checked humidity levels in January and found 72% relative humidity in their master bedroom.

Electrical rough-in work comes third. Outlets in kitchens and bathrooms that aren't GFCI protected when code requires them. Exhaust fans that are vented into attics instead of outside. Bathroom fans that aren't connected to anything—they're just holes with trim rings. One property in the Cedarvale area had three bathroom exhaust fans that weren't ducted, meaning moisture from showers was venting directly into the attic cavity. That's not a minor inconvenience—that's a path to attic rot.

Insulation gaps happen regularly. I've found rim joists in basement ceilings that aren't sealed. Thermal breaks around window frames that are missing spray foam. Attic access doors that don't have weather stripping. These aren't massive defects individually, but they add up to energy loss and higher heating bills. One Georgetown property cost the owners an extra $1,200 in annual heating expenses because thermal envelope gaps weren't sealed during construction.

Plumbing issues are less common but more expensive when they happen. I've found water lines that aren't properly supported, kitchen islands where drain lines slope the wrong direction, and basement rough-ins for future bathrooms that were never capped properly. One home had a water line that froze because it ran through an exterior wall without adequate insulation—that was a $3,400 repair in February.

Finishing defects round things out. Caulking that isn't sealed. Drywall tape that's visible. Trim that's installed without proper gaps for expansion. Paint that's applied directly over drywall primer without finish coats in closets and mechanical rooms.

None of these are deal-breakers individually. But together, they represent the gap between what you're paying for and what you're actually receiving.

The Warranty Versus What You'll Actually Find

Tarion Warranty is supposed to cover all of this. It's mandatory in Ontario for registered builders, and it includes coverage for structural defects (ten years), major defects (three years), and minor defects (one year). The builder has to respond to warranty claims within a set timeframe. It sounds comprehensive on paper.

Here's what happens in practice: The builder's warranty claim process is administered by the builder themselves. If you find water staining and the builder says it's cosmetic discoloration, not water damage, the dispute goes to Tarion. You've now spent six months going back and forth. The builder's definition of "sealed" and your inspector's definition don't align. The builder says the grading is within acceptable tolerances—even if water pools against your foundation every spring.

Tarion covers structural failure. It doesn't cover design defects or builder shortcuts that don't technically violate code. It doesn't cover your HVAC running inefficiently because ducts aren't sealed. It covers mould that's caused by a defect, but not mould that results from a design choice the builder made to save money.

I've seen Tarion claims dragged out for two years. I've watched homeowners pay for remedial work and then try to recover costs from builders who claim the work exceeded the warranty scope. The warranty is better than nothing, but it's not a substitute for your own inspection.

Why Timing Matters—Pre-Closing, Not Post

Your inspection window is critical. The best time to catch defects is the week before closing, when the builder's punch list is supposedly complete but the home is still within their maintenance access. If you discover something then, the builder has to fix it before you take possession. They have no leverage to negotiate or delay.

Post-closing inspections are worth doing for documentation purposes, but they're reactive. You've already closed. The builder's motivation to respond quickly drops significantly. Your lender won't reappraise based on post-closing findings. Your title insurance won't cover defects discovered after possession.

Ideally, you want an inspection before final walkthrough, then another one at the pre-closing stage. That costs more upfront—my typical Georgetown new build inspection runs between $650 and $850 depending on the property size and complexity—but it saves thousands in remedial work and dispute resolution down the road.

Real Georgetown Cases

The Mountainview Road property I mentioned at the start? The condensation staining turned out to be a moisture issue in the attic cavity from unsealed HVAC returns. The builder claimed it would dry out. Six months later, there was active mould growth. The repair cost $5,100 and involved removing drywall, treating the cavity, replacing insulation, and resealing everything. The builder eventually covered it under warranty, but only after Tarion's involvement.

Another property on Guelph Street had negative grading that the homeowner didn't catch until their first summer. Water was pooling against the foundation after every rain. The fix involved excavating around the foundation and resloping the grade at a cost of $6,800. The builder claimed the grading met specifications. Technically it did—the specifications were just insufficient for Ontario's climate.

A Cedarvale area home had bathroom exhaust fans vented into the attic. Within one winter, there was visible frost damage and early-stage rot on the roof framing. That inspection found it before closing. The builder had to reroute all three fans to the exterior before possession. Without that inspection, the homeowner would've inherited an attic maintenance issue that could've turned into structural damage within five years.

These aren't theoretical scenarios. These are actual properties in neighbourhoods you'd recognize.

Questions to Ask Your Builder's Representative

Before you close, you need answers on paper. Not verbal assurances—written responses.

Ask for a copy of the HVAC commissioning report. Does it show that the furnace was tested, that the thermostat is programmed, and that airflow is balanced? Or is it a blank form? Ask about basement grading—what's the slope, and has it been tested with water? Ask about exhaust fans—where are they ducted? Ask about window installation—how are thermal breaks sealed? Ask about basement egress—if there are bedrooms, are they code-compliant? Ask about utility connections—are all water lines, electrical rough-in, and plumbing properly installed and tested before drywall?

Most builders will say these things were done. Some will show you test reports. Others will give you vague assurances. The ones who hand you documentation are the ones who actually did the work properly.

If you're buying in Georgetown, check the risk assessment for your specific area at inspectionly.ca/city-risk-score. Different neighbourhoods have different vulnerability profiles based on soil type, grading challenges, and builder track records.

The bottom line is this: A new build warranty is insurance, not quality control. An inspection is quality control. You're not being paranoid by hiring an inspector for a brand-new home. You're being smart.
