Great service. Punctual, efficient. They cleaned up after themselves. And…great price. We had three estimates. They were in the middle and I’m so glad we went with Mainstream. Made the process quick and painless. Would definitely recommend

We had windows on our home fitted by Mainstream Home Improvement. Spencer (the owner) came out for the consultation & made all so easy, plus he was genuinely such a nice guy. Installation went smoothly & the crew also took the time to clean up any mess after, with not so much as a chip to our interior window frame or paintwork at all. They were very respectful of our property. Honestly..it was perfection, couldn't have gone any better! The best company we have ever worked with regarding improvements to our home. Would highly recommend!

Mainstream Home Improvement did an excellent job installing our vinyl windows. Appreciated the sales and office staff walking us through the process. Installers were detailed and efficient!
Also liked the professionalism from everyone.
We are planning to use them for future projects.
