I’m a repeat customer and the replacement window quality is what I have come to expect from them. Delivery was less than four weeks and the install crew did an excellent job. The installers came on time and cleaned up after themselves, in addition to the window installation. They replaced four windows in less than four hours.
Well done all!

The installation is happening tomorrow and we are excited to see the work once finished. The gutters were installed yesterday and they look fantastic! The installers were clean, respectful and finished the job in 1 day. Very Happy with the service. Definitely would recommend.

After an initial hiccup due to a measurement, a new shower pan was brought in and installed. The communication was good and courteous and they worked within the confines of our schedule. Kevin finished up the install and it looks fantastic. Cleaned up everything and was courteous and professional. Thank you all for a beautiful shower that will get plenty of use over the coming years.

The installers were great guys and very tidy 🙂
