Customer Reviews

Results are fantastic

I was nervous about replacing all our windows before winter, but DES made it stress-free. They stuck to the timeline, explained everything in detail, and the results are fantastic. Our energy bill has already gone down.

Mark B., Mississauga

Windows look incredible

We got quotes from three companies, and DES was the most transparent and reasonably priced. The installers were courteous, efficient, and clearly knew what they were doing. Our new windows look incredible.

Elena D., Scarborough

A great experience

DES Windows installed our new front entry door and patio sliders — the quality is top notch, and the curb appeal is amazing. Installation was quick and hassle-free. A great experience from start to finish.

Jason T., Etobicoke

Highly recommend!

Absolutely thrilled with our new windows from DES! The team was professional, fast, and left our home cleaner than they found it. Noticed a huge improvement in warmth and sound insulation right away. Highly recommend!
