Linda and Peter were extremely knowledgeable and helped guide our management team in selecting the best products for retrofitting our townhouse complex with new windows & doors. We were quite pleased with the pricing & the professionalism - from the first meeting and throughout the installation. Alliance Windows came through for us with a gorgeous product, when other companies kept stalling. I wouldn't hesitate to recommend them.

Linda & Pete were amazing! LOVE the product and service, it was installed ahead of schedule, unlike the other companies we called who took months to even get back to us. What made the big difference was it felt like they were there to help us and solve our issue with our existing situation, not just get the cheque and get out. The follow up service and warranty was also impressive, never felt like we had to harass anyone or fight to get ahold of the company. Thank you so much!
