The inspection stalls in the mechanical room, not on the roof or the furnace. The inspector crouches by the hot water tank, pulls back some insulation, and points at a length of bright orange pipe with a blue twin running next to it. Both buyer and seller go quiet, because neither one knew it was there.
That pipe is Kitec, a composite plumbing product installed in Canadian homes between 1995 and 2007. It was cheaper and faster to run than copper, so builders across Ontario used it heavily for a little over a decade. It was recalled in 2005 after its brass fittings proved prone to a corrosion process called dezincification, which can block or split a fitting without warning. A class action settlement followed in 2011.
None of that would matter much to a Kortright Hills buyer if the whole neighbourhood had been built in one stretch. It wasn't. Kortright Hills went up in three distinct waves, and the years matter more than most buyers assume, because they don't run in the direction you'd expect.
Three Decades, Three Different Kortright Hills
The earliest section, generally referred to as Woodland Glen, was carved out of the surrounding forest starting in the 1980s and into the early 1990s. The main body of the neighbourhood, the streets around Kortright Hills Public School, filled in from the mid-1980s through the late 1990s. A third and much smaller pocket, often called New Kortright Hills, followed in the early 2000s, bringing smaller lots and a different mix of home sizes.
Two specific buildings mark the edges of the risk window nicely. The condo townhomes at 60 Kortright Mews, near Ptarmigan and Pheasant Run, were built in 1995, the first year Kitec was on the market. The condo townhomes at 146 Downey Road, between Mollison Park and New Kortright Hills, went up in 2013, six years after Kitec production stopped entirely.
Put those two dates next to each other and the shape of the problem becomes clear. A buyer touring Kortright Hills and gravitating toward the newer pocket because it feels more move-in ready is walking toward the exact years when this plumbing was going into walls. A buyer looking at an older Woodland Glen bungalow from the early 1980s is looking at a home that almost certainly predates the material altogether. In this neighbourhood, older can mean safer, at least on this one point.
What Actually Makes 1995 to 2007 the Years That Matter
Kitec's problem was never really the plastic. It was the brass. The fittings that joined sections of pipe together contained enough zinc that, under the right conditions of heat, water chemistry, and time, the zinc would leach out and the fitting would degrade from the inside. Homeowners lost nothing until, in some cases, they lost a ceiling or a finished basement to a sudden leak.
The pipe is easy to spot once you know what you're looking for. It runs in bright orange for hot water and blue for cold, usually visible near the hot water tank, in a mechanical room, or under a kitchen or bathroom sink where it exits the wall. Builders stopped using it after 2007, once the recall and mounting failures made it too much of a liability, which is why the window is treated as fixed rather than approximate.
Here's a simple way to read a Kortright Hills build year before you ever call an inspector:
| Build Era | Typical Location | Kitec Exposure |
|---|---|---|
| 1980s to early 1990s (Woodland Glen) | Original streets nearest the school and older section of the neighbourhood | Predates Kitec, low exposure |
| Mid-1990s to 2007, including 60 Kortright Mews (1995) | Core Kortright Hills and early condo townhomes | Falls inside the recall window, worth checking |
| Post-2007, including 146 Downey Road (2013) | New Kortright Hills and later infill | Built after Kitec left the market |
That middle row is where the attention needs to go, and it happens to include some of the newer-feeling stock in the neighbourhood, not the oldest.
The Paperwork Nobody Reads Until It's in Front of Them
Ontario's real estate industry didn't ignore this. In 2016, the Ontario Real Estate Association added a specific Kitec question to two of its standard forms: the Seller Property Information Statement, known as Form 220, and the Residential Information Checklist, Form 820. Two new standard clauses came with it, one for a buyer to acknowledge that Kitec is present, another for a seller to confirm it was never installed.
The Real Estate Council of Ontario has also been clear that agents carry a duty here. Because Kitec is a known and well-documented defect, a salesperson representing a seller is expected to take reasonable steps to discover and disclose it rather than treat it as the buyer's problem to find. That expectation is part of why the OREA forms exist in the first place, and why a good inspection in a home from this window should include a specific look near the water heater and under the sinks, not just a general plumbing check.
What It Costs to Find Out You Have It
The financial side shows up in two places, and both can complicate a closing if they surface late.
Insurance is the first. Depending on the carrier, a home with confirmed Kitec plumbing may face a higher deductible for water damage claims, an outright exclusion for Kitec-related losses, or in some cases a declined policy until the piping is replaced. Mortgage lenders can grow cautious for similar reasons, since an uninsurable home is a hard home to finance.
Replacement is the second, and it isn't cheap. Current estimates from Ontario plumbers generally run from about $5,000 to $15,000 or more, depending on the size of the home, how much of the system needs to come out, and how much drywall and flooring has to be opened up to get at it. Homeowners in this region who want a local plumber familiar with the product have used WaterSmart Systems, which serves the Kitchener-Waterloo, Cambridge, and Guelph region and has replaced Kitec systems as part of its regular work.
None of this means a Kortright Hills home from this window is a home to avoid. It means the cost of finding out belongs in the offer stage, not after the sale.
Before You Waive a Condition in Kortright Hills
If you're buying or selling in the neighbourhood, a few habits keep this from becoming a surprise partway through a deal.
Check the build year against the table above before you fall in love with a listing. If a home sits in that 1995 to 2007 range, ask the listing agent directly whether Kitec has ever been disclosed, and make sure the SPIS or Residential Information Checklist actually answers the question rather than leaving it blank. Ask your inspector to specifically check the mechanical room and under-sink plumbing rather than assuming a general walkthrough covers it. If Kitec is confirmed, get a plumber's quote before you remove a financing or inspection condition, and call your insurance broker early enough that a coverage surprise doesn't show up the week before closing.
Sellers in this window have their own version of the same advice. Disclosing early and accurately, and having a plumber's assessment ready if Kitec is present, tends to keep a deal moving rather than stalling it at the inspection table.
Questions That Come Up Before Closing
Does every home built between 1995 and 2007 in Kortright Hills have Kitec? No. Not every builder used it, and some homes from this era were plumbed with copper or PEX. The window tells you when to check, not what you'll find.
If a home has Kitec but has never had a leak, is it still a problem? It can still affect insurance and financing, since carriers and lenders are reacting to the material itself, not just a history of failure. A clean track record helps, but it isn't a guarantee going forward.
Can I still get home insurance if the property has Kitec? Often yes, though terms vary widely by insurer. Some will cover the home with a higher deductible for water damage, others will ask for proof of replacement first. This is worth confirming with your broker before conditions come off.
What about the 1995-built condo townhomes at 60 Kortright Mews specifically? Their build year sits at the very start of the recall window, so the same disclosure and inspection questions apply there as they would to any freehold home from the same era.
Kortright Hills has always been sold on its trees, its trails, and its school. The plumbing behind the drywall doesn't show up in any of that, but it shapes the offer, the insurance quote, and the closing date just the same. If you're weighing a purchase or a sale in this neighbourhood and want to talk through what a specific street or build year means for your timeline, Andra Arnold and her team know Kortright Hills block by block, and they're here to help you ask the right questions before you're standing in front of an inspector holding a flashlight up to an orange pipe.
