Windows and doors in Olde Sandwich Towne's heritage district
Olde Sandwich Towne is the one part of Windsor, Ontario where heritage rules are already in force and a City grant can help pay for windows, doors and porches. Both are simpler than they sound. We connect you with an independent pro who can repair original sash, fit storms or quote replacements. Ask them to put it all in writing for your application.

Ontario's oldest surviving building sits here: why the rules exist
Sandwich was established in 1797, and its Duff-Baby House is considered the oldest surviving structure in Ontario. That's why the Sandwich Heritage Conservation District has been in effect since 19 October 2012.
The district isn't all old cottages. Streets like Alexander Avenue run from 1920s bungalows through Tudor and Colonial Revival houses to modest 1950s ranches. The district plan sums up the area's houses as having broad porches, double-hung windows and dormers, and it names the usual problem plainly: big wooden windows fall into disrepair, then get filled with factory units, or blocked in, to fit the old opening.
Heritage permits in plain English: what needs one and what doesn't
Table 6.1 of the Sandwich district plan sorts the work.
No heritage permit needed
- Swapping a window or door within the opening it already has, unless the window is an original and a significant visual feature seen from the street or another public space
- Putting up, replacing or taking down storm windows and storm doors
Heritage permit needed
- Removing a window or door without replacing it
- Adding a window or door in a new or altered opening
- Removing a window that's a significant feature from the street
- Replacing or removing a porch
A City building permit is a separate question. New or altered openings and porches usually need one too; see the City's permit page. Can't tell whether your front windows count as original and significant? Ask the City's heritage planners before you order anything.
The City's advice on original windows: refinish, repair, add storms
The plan is direct about it: refinishing the original window is often better than replacing it with a mass-produced vinyl one, and repair is usually a reasonable option. If insulation is the worry, it suggests adding a storm window with insulating glass.
In practice, that means freeing painted-shut sash, replacing cords, reglazing loose panes and fixing sills: everyday window repair. A storm then handles the drafts, and one with a screen panel handles July. Replacement is still on the table where a sash is too far gone. Get both priced.
Porches, dormers and double-hung windows
- Double-hung sash: sticking, rattling or cord-broken windows. The original can often stay.
- Front doors: swapping the door within its existing opening needs no heritage permit, and front doors are named in the grant.
- Porch screens: rescreening keeps an existing porch usable through bug season.
- Storefronts: shop glass and doors in the district, where the commercial grant may help.
- Dormer windows: high and awkward to reach, so mention them; access affects the quote.
The Sandwich Town CIP: help with windows, doors, porches and storefronts
The Sandwich Town community improvement plan has a residential rehabilitation grant for exterior work that names the repair or replacement of front doors, windows and porches. It allows one application per property, and the application needs two contractor estimates. Shops have a separate commercial façade and storefront grant that covers storefront doors and windows. Current amounts and terms are in the program guide.
A few things keep an application smooth:
- Talk to the City before any work starts, and ask whether work begun before approval can still count.
- Get two itemized estimates for the same scope: which windows, repair or replace, materials, and any porch or door work on its own lines.
- Check whether the work needs a heritage permit, a building permit or both.
Mention the grant on your request, and we'll aim to match you with two separate pros. The grants guide covers the rest. The City decides every application.
Olde Sandwich Towne questions
Does a window swap in Olde Sandwich Towne need a heritage permit?
Not when the new window fits the opening that's already there, as a rule. The district plan's exception is a window that is original and a significant visual feature from the street or another public space; removing or replacing one of those needs a permit. New or altered openings always do. If you're unsure about your front windows, ask the City's heritage planners before ordering.
Is my house inside the Sandwich heritage district?
The City's Sandwich HCD page shows the district, and the municipal heritage register marks every property inside it. If your address is there, the permit table above applies. Check the grant's area separately in the Sandwich Town CIP guide.
Does the Sandwich Town grant cover new windows?
It can. The residential grant names repair or replacement of front doors, windows and porches, so new windows and restored ones are both eligible work in principle. The City approves each application, asks for two contractor estimates and allows one application per property, so nothing is automatic. Read the program guide for current amounts, and ask the City about timing before work starts.
Can I replace my porch in Sandwich?
Yes, with permission. Replacing or removing a porch in the district needs a heritage permit, and porches are on the City's list of work that needs a building permit. Porches are also named in the Sandwich Town grant, so the porch can go on the same application as the windows. Rescreening an existing porch is far simpler; see porch screens.
Do storm windows need a heritage permit in Sandwich?
No. The district plan lists putting up, replacing or taking down storm windows and storm doors as work that doesn't need a heritage permit. A slim storm frame in a colour that matches the trim keeps the house looking like itself.
Do I need two quotes for the Sandwich Town grant?
Yes. The program asks for two contractor estimates with the application. Make them comparable: the same windows, the same scope, each item on its own line, taxes shown. Tell us on the request form that you're applying, and we'll try to connect you with two independent pros so you get two separate quotes, not one quote twice.
