How long should a window company have been in business before I trust them?

That's a smart question to ask before hiring anyone to work on your home. Experience and business longevity are among the most reliable indicators of quality in the window and door industry.

As a general guideline, look for companies with at least 5 years in business, though 10+ years is a stronger signal of reliability. Here's why longevity matters: window installation involves precise measurements, proper sealing, and structural considerations — mistakes don't always show up immediately. A company that's been around for a decade has had time to stand behind their work, handle warranty claims, and build a real reputation in the community.

Years in business alone isn't enough though. A newer company run by an experienced installer can outperform a long-established company that's coasted on its reputation. Look at the full picture: do they carry liability insurance and WSIB coverage? Do they carry WSIB coverage and liability insurance? Can they provide local references from Ottawa homeowners? Do they offer a workmanship warranty on top of the product warranty?

In Ottawa specifically, the harsh winters mean installation quality is critical. Ice, freeze-thaw cycles, and extreme temperature swings will expose any shortcuts within a few seasons. A company with deep local roots understands these conditions and has a track record of installations that hold up over time.

A few other things worth checking: look them up on the Better Business Bureau, search Google reviews specifically mentioning how the company handled problems (not just happy customers), and ask for proof of liability insurance and a current WSIB clearance certificate. Ottawa Window Pros does not install anything itself - it passes your job to installers who do, so put those questions to whoever quotes you. If you'd like to discuss your project, a free consultation can be arranged so you can get a feel for an installer before committing to anything.
