The Quantum difference is in everything we do. We take pride in our work and our relationships with our customers; we look at our customers as people and not just another job. We do our best to make sure that all of our customers’ needs are taken care of when we are working on their homes.

Your home is a huge investment, more than likely the biggest you will ever make. There is nothing you will spend more time and money on than your home, so when it comes to making home improvements like installing energy efficient windows, you cannot settle for anything less than the best.

An energy efficient window or door is only as good as the installation company that installs it. Unlike other companies that are here today and gone tomorrow, we have over 15 years of experience installing windows and doors and our commitment to our customers has never changed.

All of the products used by Quantum Windows and Doors are Canadian made and approved by the C.S.A. and custom designed to fit your home. They both meet and exceed the guidelines and standards of Energy Star meaning you get only the best product installed in your home.

So if you are looking into having energy efficient windows and doors installed in your home this year, there is only one obvious choice in companies to choose from. Call us today and see the difference customer commitment makes when improving your home. See the Quantum Windows and Doors difference and know that you are getting only the best in customer service and window and door installation.
