Windows in Sydenham Ward's limestone streets
Sydenham Ward, the downtown neighbourhood between Princess Street and the lake in Kingston, Ontario, holds many of the city's historic limestone buildings, and plenty of them are rented. So two kinds of window job share its streets: old wood sash and storm windows under heritage rules, and window screens, panes and locks between tenants. We connect owners, landlords and tenants with independent local pros who do this work. This page is about the downtown ward, not the village of Sydenham in South Frontenac.

Old Sydenham: Kingston's largest heritage district
Old Sydenham became a heritage conservation district in 2015. It is the largest of the City's three, running from Johnson Street to the lake between Barrie Street and King Street East. The ward mixes permanent homes with student rentals.
For windows, that means exterior changes may need approval, and the first question is usually whether the original sash can be kept.
Keeping original sash and storms working
Most sash problems in a stone house are repairs. A sash that won't stay up usually has a broken cord or balance. A rattle or a draft usually means worn weatherstripping or loose glazing putty. A cracked pane can be cut and reglazed into the existing sash without touching the frame. Our wood window repair page covers each.
In thick stone walls, a storm window fits against masonry rather than a neat modern frame. Each autumn the storms go on and the window screens come off, and each spring the reverse: the moment to catch cracked glass, a lost latch or a poor fit. The storm windows page explains repair and replacement.
Heritage approval before exterior window changes
If your house is designated or inside Old Sydenham, changing its windows generally needs a heritage permit before work starts. Work the City treats as maintenance is exempt, and minor alterations are usually approved by staff rather than Council. The City's building permit page also mentions "any work … on a heritage building", so the careful move is a quick call to Heritage Planning before booking anything beyond a straight repair. Ask for its Window Renovations in Heritage Buildings Policy, sent on request.
Designated owners can also apply for the City's Heritage Property Grant, which is tied to a heritage permit. The pro we match you with can provide photos and a written quote for either application.
Student rentals: window screens, panes and hardware between tenants
Rented houses here follow the university year. Between leases is the easiest time to rescreen torn window screens, replace a cracked pane, fix a sash lock or free a window painted shut.
Landlords can put several problems, or several houses, in one request, with a photo of each. Our move-in and move-out guide has a photo checklist for the walk-through. Tenants: tell your landlord first, since repairs to the house normally go through them.
What to tell the pro before the visit
A little information up front saves a wasted trip:
- your street, and whether the house is designated or inside Old Sydenham (if you don't know, say so);
- a photo of the whole window from inside and outside, plus a close-up of the problem;
- whether it's wood sash, a storm window, a newer thermal unit or a window screen;
- for rentals, the move-out date and how tenants can arrange access.
Sydenham Ward questions
How do I know if my house is inside Old Sydenham?
Check the map on the City's conservation districts page, or ask Heritage Planning. The district runs roughly from Johnson Street to the lake, between Barrie Street and King Street East, so confirm your address rather than guessing. A house outside it can still be designated on its own. Our downtown page covers the Market Square district next door.
Can a sash that's been painted shut be freed without damaging it?
Usually. A pro cuts through the paint line, eases the sash and its stops free, and checks the cords or balances while it's open, since a painted-shut window often hides a broken cord. It's a repair, not a change, so the original window stays in place. In a rental, it's worth doing between tenants. Our wood window repair page covers the rest of the work.
My rental is in Old Sydenham. Do turnover repairs need heritage approval?
Most don't. Rescreening window screens, reglazing a cracked pane, fixing a lock or refitting weatherstripping keeps the window as it is, which usually counts as maintenance. Replacing windows or changing how they look is different and generally needs a heritage permit first. If a job sits in between, call Heritage Planning before booking. Our rental turnover guide covers the walk-through.
Who at the City answers questions about heritage windows?
Heritage Planning. Staff there can confirm whether your house is designated or inside Old Sydenham, tell you whether a job counts as maintenance, and send the City's Window Renovations in Heritage Buildings Policy on request. Contact details are on the City's heritage page. Call before changing a window's size, material or look. Our heritage windows guide lists useful questions.
Why is there frost or condensation between my storm window and the sash?
Usually because warm, humid indoor air is leaking past the inner sash and meeting the cold storm glass. The fix is on the inside: new weatherstripping or putty so the sash seals better, while the storm stays slightly looser to let moisture out. If the storm is the tighter of the two, the problem tends to get worse. Our storm windows page explains how the two layers work together.
