About UGS Windows & Doors
UGS Windows & Doors is a locally owned window and door company serving homeowners across Toronto and Ontario. We focus on one thing and one thing only: upgrading homes with high-performance, energy-efficient vinyl windows and doors that are installed properly, look great and last.
We're not a big national chain. We're an owner-led, Ontario-based team that has spent years in real homes, on real job sites, solving real problems — drafts, leaks, noise, rotting frames, fogged glass and skyrocketing energy bills. Every project we take on is handled by WSIB-insured, manufacturer-trained installers who treat your home with the same care as their own.

Meet Our Founder
Before starting UGS Windows & Doors, our founder spent years working hands-on as a window and door installer across Toronto and the rest of Ontario. He saw the industry from the inside — the good, the bad and the "never again":
- ✕rushed installations that ignored building science,
- ✕cheap, builder-grade windows that failed after a few winters,
- ✕homeowners left in the dark with vague quotes and broken promises.
Standing in cold, drafty living rooms and listening to frustrated homeowners, he realized something simple:
"If we just treated every home like our own, and every quote like it had our own name on it, this industry would look very different."
UGS was built around that idea. He wanted a window and door company where:
- ✓the person giving the quote truly understands installation,
- ✓the crews are accountable and properly insured,
- ✓recommendations are made for Ontario's climate — not just to hit a sales target.
To this day, our founder remains directly involved in projects, training and quality control, ensuring that every installation reflects the standards he built his reputation on.
Our Philosophy: How We Treat Your Home
We don't see your project as "just another job." Windows and doors are the barrier between your family and everything outside — weather, noise, time. Done right, they make your home warmer, quieter, brighter and safer for years. Done poorly, they become a constant source of frustration.
Our philosophy is built on four simple principles:
Honest, no-pressure advice
We take time to explain your options — different window styles, glass packages, and whether retrofit or full-frame (brick-to-brick) installation makes the most sense. You get clear pros and cons, in plain language, so you can make a confident decision without pressure.
Respect for your home and time
We show up when we say we will. We protect your floors and furniture, manage dust as much as possible and clean up thoroughly before we leave. Our goal is for you to feel that the only sign we were there is your new windows and doors.
Long-term thinking over quick sales
We recommend solutions that make sense for Ontario's climate and your specific home — not just what's on promotion this month. We'd rather walk away from a project than sell you something we don't believe is right for the long run.
Clear communication from quote to final walkthrough
From the first call to the last inspection, you know who your contact person is, what's happening next and what it will cost. No surprises, no hidden fees, no disappearing acts once the final invoice is paid.
How We Work: Installation Standards That Matter
Even the best window or door can fail if it's installed poorly. That's why our installation standards are intentionally higher than what's considered "good enough" in the market.
In-house, WSIB-insured crews
We don't hand your home to random subcontractors. Our installers are part of the UGS team, fully WSIB-insured and trained to follow both manufacturer guidelines and Ontario building standards.
Expertise in both retrofit and full-frame replacement
We don't push a single method just because it's easier for us. For each opening, we inspect the existing frame, structure and insulation, then recommend either retrofit installation or full-frame (brick-to-brick) replacement based on what will perform best over time.
Attention to energy-efficient details
We use high-quality insulation, sealants and flashing practices to help your windows and doors reach their full Energy Star potential. That means correctly foaming around frames, properly sealing sill and head joints and ensuring there are no shortcuts hidden behind trim.
Clean, efficient work on installation day
For most homes in Toronto and Southern Ontario, we complete window replacement in a single day. We protect your space, remove old units, install new ones, clean up indoor and outdoor work areas and haul away debris — so you can get back to normal life quickly, just with a more comfortable home.
Why Homeowners Across Toronto & Ontario Choose UGS
There are many companies that sell windows and doors in Ontario. Homeowners choose UGS when they are tired of guesswork and want a partner they can trust with their home.
Local expertise in Ontario's climate
We live where we work. We understand how freezing winters, humid summers, lake-effect winds and city noise affect windows and doors in real Ontario homes. Our recommendations are based on experience, not theory.
Energy-efficient, Energy Star–rated products
We focus on vinyl windows and doors that meet or exceed Energy Star criteria for Ontario. That means better insulation, fewer drafts, reduced noise and the potential to lower heating and cooling costs.
Clear, itemized quotes — not "ballpark" numbers
You receive a detailed written estimate that breaks down product choices, installation methods and any additional work such as interior trim or exterior capping. Everything is explained up front so you're never surprised later.
Real warranties and after-service
We stand behind both the products we install and the workmanship of our crews. If something needs adjustment, you call us directly — not a call centre. Our reputation is built on what happens after the project, not just the day we get paid.
Projects from Toronto condos to Ontario cottages
We've upgraded windows and doors in downtown Toronto condos, suburban semis, brick bungalows, rural farmhouses and lakeside cottages. Whatever type of property you own, chances are we've worked on something very similar.
Verified reviews and referrals
A large percentage of our work comes from repeat clients and referrals. Our Google and HomeStars reviews reflect what we strive for on every project: respectful crews, honest communication and installations that simply do what they're supposed to do.
