Frequently Asked Questions

How do I find the best window company in Ottawa?

Start with online reviews on Google and HomeStars, check Better Business Bureau ratings, get at least three detailed quotes, verify insurance and certifications, and ask for recent Ottawa references. Prioritize companies with strong product knowledge and fair, transparent pricing.

What should I look for in a window installer?

Look for trained, experienced installers who follow manufacturer protocols, properly flash and seal openings, insulate around frames, and maintain clean work sites. Ask whether the company uses employees or subcontractors for installation.

Are national window companies better than local Ottawa companies?

Not necessarily. Local companies often provide better value through lower overhead, personalized service, and community accountability. National companies offer brand recognition and standardized processes. Compare quotes for equivalent products to determine best value.

What warranty should I expect from a good window company?

Expect a manufacturer warranty of 20 to 25 years or lifetime on the product, and an installation warranty of 5 to 10 years from the company. The best companies stand behind both warranties without deflecting responsibility.
