From Main Street’s Heritage Homes to Stonehaven-Wyndham: Entry Door Installation in Newmarket

Why Newmarket Homeowners Choose Stone River

We supply, install, warranty, and service every door ourselves, so there’s one company to call if anything needs attention later. Our own fleet of tractor-trailers delivers directly to the job site rather than relying on a third-party carrier’s schedule. Free consultations are available at our Toronto Planning Studio or our Oshawa Showroom.

Entry Doors in Newmarket’s Heritage District and Beyond

Homes along Lower Main Street South sit inside Newmarket’s only heritage conservation district. Any alteration to a door, its frame, or its surround there needs a heritage permit reviewed by the Town’s Heritage Conservation District Advisory Group, on top of any building permit. We work within those requirements rather than around them, matching new doors to the profile and proportions the district calls for.

Outside the heritage district, the rule is simpler: replacing a door with one the same size doesn’t require a building permit. Enlarging or relocating the opening does.

In newer subdivisions like Stonehaven-Wyndham and Bristol-London, the openings are standard and the heritage rules don’t apply, so these projects are usually about upgrading security and efficiency rather than matching a historic look.

Signs It’s Time for a New Entry Door

• Daylight visible around the frame when the door is closed
• The door drags, sticks, or needs a shoulder to shut fully
• Rising winter heating costs with no other explanation
• Visible warping, rust, or rot on the door or frame

Frequently Asked Questions

Do I need a heritage permit to replace my entry door in Newmarket?

Only if your home is inside the Lower Main Street South Heritage Conservation District. There, any alteration to a door, frame, or surround needs a heritage permit reviewed by the Town’s Heritage Conservation District Advisory Group. Outside the district, a same-size replacement doesn’t need a building permit.

Fiberglass or steel, which holds up better in Newmarket winters?

Both perform well when installed correctly. Fiberglass resists denting and holds paint or stain finishes longer, while steel tends to cost less upfront. We can walk through the tradeoffs for your specific entryway.

What affects the cost of an entry door installation project?

The door material, glass and hardware options, whether the frame needs any adjustment, and heritage requirements if your home is in the Lower Main Street South district. A free consultation covers these specifics.

How long does an entry door installation take?

Most single-door installations are completed in a day.

Do you service entry doors after the warranty ends?

Yes. We offer post-warranty repair and maintenance service.

Which brand do you install for entry doors in Newmarket?

We are an authorized Therma-Tru dealer.
