Since opening in 1996, Hartmann Windows & Doors has been proudly serving Guelph and the surrounding area.  From day one, our focus has been simple — do quality work, supply great products and treat people right.

Our goal on every project is not just to meet expectations, but to exceed them. We take pride in the details, use high-quality products, and believe in being honest, straightforward, and genuine with every customer we work with.

We’ve carefully chosen manufacturing partners with strong reputations for quality and reliability, and all of our products are proudly Canadian, built right here in Ontario.

If you’re looking for the kind of care and accountability that comes from working with a local business, we’d be happy to help. We’re confident you’ll appreciate the difference.
