Old Maple's original windows usually need paint-safe repair and new sealant. A newer Maple build usually needs only fresh caulk and weatherstripping. Check the paint's age before scraping, and match the caulk to the gap.
Maple is really two housing stocks. West of Keele and south of Major Mackenzie, the Old Maple pocket still has homes that go back to the 1950s (many have been torn down for custom rebuilds). Much of the rest is newer construction. A draft around a window means something different on each side, so the fix and the order of operations differ too.
Why it matters before winter
Hydro One says air leakage causes 25 to 40 per cent of the average home's winter heat loss and summer cool-air loss, and that a thorough job of caulking, weatherstripping and insulating can cut heating and cooling bills by as much as 25 per cent. Treat those as general figures: windows and doors are only part of the leakage, and your own result depends on the house.
An Old Maple original: check the paint first
If the windows and trim are original, expect many layers of paint. Health Canada says a home built before 1960 probably contains lead-based paint, and that the exterior of a home built between 1960 and 1990 may. It also says not to use sanders, heat guns or blowlamps to remove paint in older homes, because that creates dust and fumes containing lead, and that you can have paint tested by a certified inspector or a testing lab.
In practice, that changes the job. Scraping a frozen-shut sash or stripping a sill before recaulking is not a casual afternoon task in a 1950s home. Intact paint that nobody chews or rubs is low risk, per Health Canada, so the safer move is often to leave it intact and seal around it. Ask any contractor how they will contain dust before they start.
Hydro One's advice for a window in good shape: where the trim can be removed, add insulation around the frame; where it cannot, caulk around the trim. If a window is damaged beyond repair, it recommends high-efficiency replacement. Doors should close firmly with no daylight at the sides, top or bottom; rubber weatherstripping, it notes, costs only a few dollars.
A newer Maple build: the sealant is the aging part
In a home from the 2000s or later, the frames are rarely the problem. The usual culprit is exterior caulk that has cracked or pulled away from the siding or brick, and door weatherstripping that has flattened or torn. Hydro One notes many caulks last 20 years or more, which means a home built in the mid-2000s can be reaching that age now. Look along the top and sides of each window and at the threshold of the patio and front doors.
Picking the right caulk and weatherstripping
- Read the label. Hydro One says products often aren't interchangeable: check for indoor or outdoor use, paintability, the gap size it fills, and its expected lifespan.
- Mind the temperature. Hydro-Québec's caulking guide advises against caulking when it is colder than 5°C because the compound stiffens. Follow your product's label.
- Remove the old bead. Fresh caulk over failed caulk fails again.
- Ventilate while it cures, as Hydro One advises.
Permits and heritage questions
Vaughan's door and window openings page says a building permit is required to cut a new window or door opening into an exterior wall or to widen an existing opening. Resealing and weatherstripping inside the existing opening is not what that page describes, but confirm any replacement plan with Vaughan Building Standards before you start.
Maple also has a Heritage Conservation District, enacted under By-law 167-2007, centred on Keele and Major Mackenzie. The 2006 study behind it removed postwar residential areas from its study area, so most Old Maple streets of 1950s homes are likely outside it. Do not assume that about your address: check Vaughan's heritage records or ask Vaughan's cultural heritage staff, since a property inside the district may need a heritage permit for exterior changes.
Quick answers
Should I reseal windows in the fall or spring?
Fall works if temperatures hold above your caulk's minimum, since one utility guide says not to caulk below 5°C. Check the product label, because minimums differ by product.
Does resealing a window or door need a permit in Vaughan?
Vaughan's page says a permit is needed to cut a new opening or widen an existing one. Resealing in place isn't described there, so confirm with Building Standards.
Is old window paint in Maple likely to contain lead?
Health Canada says a home built before 1960 probably has lead-based paint, and a 1960 to 1990 home may on the exterior. Test before you scrape.
How much heat do leaky windows and doors waste?
Hydro One says air leakage causes 25 to 40 per cent of an average home's winter heat loss. Windows and doors are only part of that.
Can someone else do the resealing for me?
Yes, and it's a reasonable small job to hand off, especially at height or on painted old trim. Rhodex can quote it as a fixed price.
A short checklist
Run a hand along each window and door on a windy day, note where you feel air, and decide which side of Maple you are on: paint-safe repair and sealing for an original, fresh caulk and weatherstripping for a newer build. Do it before the first hard cold, not after.
