Professional Window Installation Services — GTA to Barrie
Expert window installation from a local, family-owned team. Our own licensed, insured crews measure, remove, install, seal and clean up — no subcontractors, no mess left behind. Serving the Greater Toronto Area north to Barrie.
Installation Done Right
A Professional Install Is What Makes a Window Perform
Even the best window underperforms if it is installed out of square, poorly sealed, or badly insulated. That is why professional installation matters as much as the window itself — a proper fit is the difference between decades of comfort and energy savings, and years of drafts, leaks and sticking sashes.
At WindowFixers.ca we both supply and install every window with our own trained crews. From the free in-home measurement to the final walk-through, one accountable local team handles your whole project — and full cleanup is always part of the job.
What to Expect
Our Window Installation Process
A clear, five-step process so you always know exactly what happens next — from your first measurement to the final walk-through.
Free In-Home Measurement
We visit your home, measure every opening precisely, review your style and glass options, and give you an upfront, all-in written price — no pressure, no obligation.
Custom Manufacture
Every window is custom-ordered to your exact opening from trusted Canadian suppliers. No standard-size compromises. Typical build time is 3–5 weeks after measurement.
Professional Removal & Install
Our own crew removes your old units one opening at a time, sets the new window level and square, and seals and insulates it fully before moving to the next — so your home is never left exposed.
Sealing, Finishing & Cleanup
We finish interior and exterior trim, apply weather-tight sealant, haul away every old window and all debris, and leave your home spotless — cleanup is always included.
Final Walk-Through & Warranty
We walk every window with you to confirm smooth operation and a clean finish, then back the job with the manufacturer warranty plus our own installation workmanship guarantee.

Professional vs. DIY
Why Professional Installation Pays Off
A window is only as good as its install. Here is how a professional installation compares to going it alone.
| Consideration | Professional Install | DIY |
|---|---|---|
| Precise fit & square install | Measured and set level by trained crews | Easy to install out-of-square, causing drafts & sticking |
| Air & water sealing | Fully insulated and weather-sealed to code | Gaps and leaks are the #1 DIY failure point |
| Warranty protection | Manufacturer + workmanship warranty intact | Improper install often voids the product warranty |
| Old window removal & disposal | Included and hauled away | You arrange lifting, hauling and disposal yourself |
| Time & safety | A crew completes most homes in 1–3 days | Slow, and second-storey work is genuinely risky |
| Final result | Clean lines, smooth operation, energy savings | Variable finish and lost efficiency if sealed poorly |
