Denise McMullan from York

I replaced all my windows in my triplex (23 windows). I couldn't afford to do them all at once. GTA windows gave me a quote one third of the project. No pushy sales, he suggested I get other quotes. The installation was completed within 2 days. I returned to GTA 2 years later to do another 1/3 and a year later to finish the project at the original quote. Excellent company and professional installers
