Rebate-Qualifying Window Installation in Newmarket
ENERGY STAR® certified windows installed brick-to-brick, with finishes that work inside Newmarket's heritage district and beyond.
Newmarket homeowners replacing older windows have two goals that often overlap: a warmer, quieter house and a project that qualifies for the current Ontario rebate program. The right window, installed the right way, can do both — as long as the product, the installation method, and the rebate paperwork are planned together from the start.
ENERGY STAR® Windows and the Home Renovation Savings™ Rebate
The Home Renovation Savings™ program, delivered by Enbridge Gas and Save on Energy with support from the Ontario Government, offers rebates for qualifying energy-efficiency upgrades. For windows and doors, the program currently pays $100 per rough opening when ENERGY STAR® certified units are installed as part of a project that includes at least two qualifying upgrade categories.
That means a window-only replacement does not qualify on its own. Pairing windows with attic insulation or air sealing is the most common path for Newmarket homeowners to clear the two-upgrade requirement. A pre-work home energy assessment is mandatory, and it must be scheduled before any materials are ordered or installation begins.
Trust Build installs ENERGY STAR® certified vinyl windows rated for Ontario's climate zone. We do not promise rebate approval — eligibility is determined by the program — but we quote and install the product stream that meets the program's efficiency requirements so the application is based on a qualifying install.
Custom Colours and the Lower Main Street South Heritage District
Window colour is not just a curb-appeal decision in Newmarket. Properties within the Lower Main Street South Heritage Conservation District — 72 designated properties under Part V of the Ontario Heritage Act — must obtain a heritage permit before changing exterior-facing window frames, sashes, or trim that is visible from the street. The replacement generally needs to match the building's original character, which often means heritage-appropriate profiles, divided-lite patterns, and subdued colour choices rather than bold modern finishes.
Outside the heritage district, homeowners have more freedom, but colour still matters for resale and neighbourhood context. We offer a range of interior and exterior frame colours, including neutral tones that blend with brick, stone, and siding common in Newmarket subdivisions, as well as wood-grain laminates for a warmer look without the maintenance of real wood.
Brick-to-Brick Installation
We install windows brick-to-brick, not as inserts swapped into the old frame. The crew removes the brick mould, the old window and frame, the jamb extensions, and the interior casing, working from a clean rough opening. The opening is inspected for water damage, sealed with a waterproof membrane such as Blueskin, and shimmed plumb, level, and square before the new unit goes in.
The new window is sealed with low-expansion foam, taped, and finished with new interior casing. On older homes near Main Street and the historic core, plaster-and-lath walls need extra care when trim is removed; we score paint lines first and use solid wood casing — never MDF — so it takes paint or stain the way the original trim did.

Frequently Asked Questions
What makes a window replacement qualify for the Home Renovation Savings™ rebate in Newmarket? The window must be ENERGY STAR® certified and installed as part of a project that includes at least two qualifying upgrade categories, such as windows plus attic insulation or air sealing. A pre-work home energy assessment is also required.
Can I replace windows in Newmarket's Lower Main Street South Heritage District? Yes, but exterior changes to designated heritage properties require a heritage permit from the Town of Newmarket before work begins. We plan that timeline into the project schedule and help select finishes that respect the district's character.
What is brick-to-brick window replacement? Brick-to-brick means the old window, frame, brick mould, and interior trim are removed down to the rough opening. The new unit is installed with proper waterproofing, insulation, and finished trim rather than inserting a smaller window into the old frame.
How much is the rebate for windows and doors? The Home Renovation Savings™ program currently offers $100 per qualifying rough opening for ENERGY STAR® windows and doors when bundled with another eligible upgrade. Exact eligibility is determined by the program, not Trust Build.
