Replacement Windows & Doors Done Right
Ontario’s Window & Door Experts Since 2017
Residential Window Replacement for Ontario Homes
If your windows have started letting in cold air, fogging up between the panes, or sticking when you try to open them, you're not alone. Many Ontario homeowners face the same issues as their windows age, and replacement is often the simplest way to restore comfort and lower your energy bills.
We're based in Newmarket and see this across homes throughout the GTA. Every project starts with custom measurements of your existing openings, since no two homes are identical. Once your new units are ready, we remove the old windows, fit the replacements, and weather-seal around each frame to keep air and water out.
Newer windows also tend to run more efficiently than older units, easing the load on your heating and cooling system year-round. Homeowners replace their windows for a mix of reasons: comfort, energy savings, appearance, and simply wanting windows that open and close properly.

Vinyl Replacement Windows for Ontario Home
Vinyl windows are a popular choice for Ontario homeowners who want a low-maintenance option that holds up well over time. Unlike wood frames, vinyl won't rot, warp, or need repainting, and it resists moisture better in humid summers and freezing winters alike.
Vinyl frames also provide solid insulation, helping keep conditioned air inside your home through Ontario's seasonal temperature swings. We custom-size every window to your existing openings, so you're not stuck choosing from generic, one-size-fits-all units.
We offer several vinyl window styles to fit different rooms and needs, from operable options that maximize airflow to fixed windows built for extra natural light. The infographic below shows the styles available through Window Experts, so you can compare options before choosing what's right for your home.

Our Window & Door Testimonials
“I have used the Window Experts a few times over the last few years when upgrading my entry door, sliding doors, and windows. Each time I have encountered an exceptional service: fair pricing, quality windows and doors, as well as very clean and thorough work during the installation.”
“Replaced 14 windows and 2 doors. Was very happy with the team. They took the time to explain the products, find solutions that work, and worked around my schedule and the general home renovations to get the work done!”
“I recently had my upstairs windows replaced by Window Experts. I am extremely happy with the results. The work was completed in one day, with a minimum of disruption and absolutely no mess left behind. I would certainly recommend Window Experts.”
The Window Expert Approach
Our window and door replacement process moves through three clear steps, keeping your project transparent, on schedule, and built around your home.
Window Replacement vs New Window Installation
Homeowners often use window replacement and window installation interchangeably, even though the two projects can differ in scope. Window replacement usually means swapping an existing window for a new one in an opening that's already the right size, so the project focuses on removal, fitting, and sealing.
New window installation can involve more, especially when you need to create, enlarge, or structurally modify an opening to fit the selected window. That kind of project adds steps like framing and exterior finishing beyond what a straightforward replacement requires. Not sure which one your project needs? Our installation page walks through the full process in more detail.
What Affects Window Replacement Cost?
There's no single price for window replacement, since the right scope depends on your home and your project.
Factors that can affect your quote include:
- Number of windows
- Window size and style
- Double- or triple-glass selection
- Selected finishes and trim
- Condition of the existing frames and openings
- Installation method
- Access to the windows
A straightforward replacement using an existing opening typically involves less work than a large window, an unusual configuration, or an opening that needs extra preparation. We provide pricing after measuring your openings and reviewing your selections, so your quote reflects your actual project rather than a generic estimate.
