Most of a newer Stouffville home's small repairs are yours once Tarion's first two years end: caulking, grading, drywall touch-ups and deck nails. Only major structural defects stay covered, for seven years from possession.
Stouffville has a lot of newer subdivision housing around the Ninth Line corridor, and a house there tends to be sold as "basically new" for a long time. The paperwork tells a different story. Tarion, Ontario's new home warranty program, has three clocks, all of which start on the day you take possession, and by year three only one of them is still running. This guide sorts out which small jobs belong to the builder, which belong to you, and which ones the Town of Whitchurch-Stouffville has an opinion about.
The three Tarion clocks
According to Tarion's coverage overview, the first year covers defects in work and materials, Building Code violations and unauthorized substitutions. The second year covers water getting in through the building envelope or basement walls, exterior cladding, the electrical, plumbing and heating delivery systems, and Building Code violations affecting health and safety. Years three to seven cover major structural defects only, such as significant basement wall cracking or soil movement.
Claims are filed on set forms. Tarion's timelines page lists an Initial Form that auto-submits on day 41, a Mid-Year Form that closes on day 183, and a Year-End Form that closes on day 365 with a 10-day grace period that needs written proof you told your builder during year one. Year two has its own form, and the structural form runs up to day 2,555. If your house changed hands, ask Tarion how the warranty transferred rather than assuming it did.
What a home under 10 years old actually needs
A house in its third to ninth year is past the one- and two-year coverage, so these are the jobs that show up. Each one below is checked against Tarion's own Construction Performance Guidelines (updated June 2024), which are the yardstick Tarion uses to decide what is a warranty item.
- Caulking and sealants. The guidelines say caulking around tubs and showers and entry door seals needs regular homeowner inspection, that grout between tiles can deteriorate under normal use, and that exterior sealants deteriorate under normal weather and should be checked regularly. Re-caulking a tub and gaps around windows and doors is the single most common small job in this age of house.
- Drywall. Nail pops from normal drying shrinkage are excluded from the warranty even in year one, and the guidelines note repairs are often best left until the framing has settled. Ceiling-to-wall cracks from truss uplift, which happens when outdoor temperatures are well below indoor ones, are treated the same way: crack widths over 4 mm are the benchmark, and repairs should wait until the truss returns to position. Expect to fill and repaint these yourself.
- Deck nails. Nailheads on a deck rise over time, and the guidelines call resetting them part of regular home maintenance.
- Grading and ponding. The guidelines expect water not to accumulate next to the house, with a minimum slope of 2% where no grade is specified (1% for sodded or graveled areas). After the first year, they say the homeowner is responsible for maintaining the finished grading. Settling of walkways and driveways is not covered, and neither is subsidence or changes you made through landscaping.
None of this makes the builder irrelevant. A leak through a wall or window in year two, or a dead furnace, is still a builder and Tarion matter. Call a handyman only after you have ruled that out.
Before you fix anything, document it
If you are still inside year one or two, photograph the problem and send it to your builder in writing before anyone touches it. Repair work you commission yourself can muddy a claim. The guidelines also point out that drywall damage not recorded on your pre-delivery inspection form is excluded unless you can show the builder caused it, which is why that walk-through matters. Our guide to documenting work for a warranty claim covers the habit in more detail.
Fixing a low spot in the yard: check the Town first
Regrading sounds like a weekend job, but the Town of Whitchurch-Stouffville regulates it. Its site alterations page says By-law 2024-037-RE applies to any work that alters the existing grade of land, and lists building a berm or retaining wall and moving or re-routing a driveway as examples that need a permit. The by-law includes a one-time exemption for importing clean fill, scaled to lot size from 10 cubic metres on lots of 0.1 hectares or less. Development Engineering can be reached at developmentengineeringhelp@townofws.ca or (905) 640-1900.
The practical point: a lot in a subdivision was graded to an approved plan, with swales that carry water between neighbours. Regrade your side without understanding that plan and the water may end up on someone else's lot, or back at your foundation.
Quick answers
How long does the Tarion warranty last on a new home in Ontario?
It runs one, two and seven years from your possession date, covering different things in each period. Nearly all small repairs fall in the first two years.
Does Tarion cover drywall nail pops?
Not when they come from normal shrinkage as materials dry after construction. Tarion's guidelines exclude those, and any dents or gouges not listed on your pre-delivery inspection form.
Who fixes ponding water in my backyard after the first year?
You do. Tarion's guidelines say that after the first year the homeowner is responsible for maintaining the finished grading so ponding water does not adversely affect the home.
Do I need a permit to fill low spots in my Stouffville yard?
Possibly. Whitchurch-Stouffville's site alteration by-law covers any work that changes the existing grade, with a one-time exemption for small amounts of clean fill. Call the Town first.
Is a home that's eight years old still under Tarion warranty?
Only for major structural defects, which are covered for seven years from possession. The one- and two-year coverage has ended, so ordinary repairs are your own responsibility.
A short checklist for year three onward
Once the warranty clocks are behind you, a once-a-year walk-around catches most of what this age of house needs: look over every caulk line inside and out, reset deck nails, watch where water sits after heavy rain, and note any new cracks with a date and a ruler. Most of it is an afternoon of small work. Anything that looks like water coming in or movement in the foundation is worth a proper inspection first.
If you would rather hand the afternoon list to someone, you can get a fixed price from Rhodex.
