ECOTECH WINDOWS & DOORS REVIEWS

Hands down one of our best experiences of working with one of the smoothest run companies. Right from picking up a model for an exterior door and a patio to completing the installation - All the process were so smooth and very well communicated - thoroughly happy with the installers as well! Left the place thoroughly cleaned, and installed in half a day!.

The crew from Eco Tech arrived to install two exterior doors as planned. The men that arrived were very polite and definitely take pride in their work. Beautiful job and true craftsmanship. Dmytro Lysak is a pleasure to work with. I am so pleased and can’t say enough good things. Attention to detail is impeccable. Would hired them again!!.

The gentlemen doing the installation were polite and respectful of our home. The windows look great. The entire process of getting the windows was easy. All steps were clearly outlined and followed. I would recommend EcoTech to others.

SUDBURY WINDOWS AND DOORS POLAR BEAR REVIEWS

Excellent service from receiving an estimate to the completion of the job. When we had to call for clarification regarding installation dates and time, they were very quick in getting back to us with clarification. Our installation techs were Rob and Ryan. They were both very professional in everything they did in installing our windows and replacing the cranks on our windows. Very courteous and thoughtful in making sure that the installation was done with care. Even took such time and care when cleaning up after the install. We highly recommend this company for any type of window install. Thank you Sudbury windows and doors - Polar Bear.

Rob and Ryan did an amazing job with the installation of three new windows for us. They were meticulous with all aspects of the job, from covering our floors to removing any trace of old caulk/paint on the brickwork to cleaning the windows when they were done, no details were overlooked. The windows were skillfully trimmed inside and out and look beautiful. I highly recommend this company and plan to use them again.

Honestly, I could not be more pleased with Polar Bear Sudbury Windows and Doors for the fast and efficient work done by their fantastic team installing my new windows. It was a pleasant experience from beginning to end. Tessah, the estimator who prepared the quote was very easy to deal with and she certainly new her stuff. As well as the well organized crew who worked as a team and left the place spotless after installing the windows. They were very quick! They new what they were doing and it was all coordinated beautifully. Very impressed! I would highly recommend them! Very professional workmanship!.

M. CHAMPAGNE SIDING LTD. REVIEWS

Champagne Siding were extremely pleasant to deal with. The crew was very professional and quick. The quality of materials and workmanship were outstanding. Had some minor issues after installation and they were here to remedy it right away. Very impressed with after sale service as well. Would highly recommend this company. Thanks guys!.

Chris made this an easy experience for me, great advice and great pricing as well. When I went to pick this up and square up my bill, the girl at the counter was very friendly and not one but 3 guys helped load my trailer up. Fantastic service, hard to find that kind of help these days. Super impressed, thank you! (And no, I'm not related lol).

Patrick, the owner himself, served us. We were there about an hour picking out windows and doors. He took the time and made sure we were satisfied. His prices were cheaper than Contractors Wholesale. Excellent service. Couldn't ask for any better. I recommend him to everyone.
