“We refer Windows Mississauga as a professional company to do home renovation with. They transferred our front square windows into bay windows. The job was done professionally and on time. We liked the attitude of installers Edward and Serge – good job!” – Alex VERIFIED HOMESTARS.CA REVIEW



“I am writing a review in regards to my new fibre glass door that was installed recently in my home. We contacted Direct Windows for an estimate along with a few other suppliers. We liked the way Serge, the estimator presented their product. We also saw 3 front entry doors installations in our area, spoke with happy home owners and made our decision. Windows Mississauga Windows installers came on time, removed the old door and installed a new one. We liked the professionalism and their attitude. They finished in 4 hours of non-stop work and left taking along the garbage. We appreciate the work done a lot and recommend them for any one shopping for windows and doors.” – Jack Campbell VERIFIED HOMESTARS.CA REVIEW



“The old window was very old and the interior framing had rotted over 3 decades. Serge and his excellent assistant installed the new one in just one (long) day and did an excellent and professional job. At one point, they were finishing the caulking and could have rushed it, but they kept on touching and retouching the work to get it just right! They also had to rebuild and fortify the base of the window to replace the damaged sections. In addition to the top quality workmanship, Serge accomplished a miracle. My schedule was such that I had a very narrow window (no pun intended) to get it done. Unfortunately, although the order for the new window had been placed, it had somehow gotten ‘lost’. Serge magically got the window in one week! If you’ve ever ordered a custom measured large window you may know it can often take 6 to 8 weeks! Luckily, he got it and installed it in the nick of time. The day after it went in, Toronto had a ferocious ice storm on April 14. I will forever be grateful to Serge!!! Without hesitation, I would recommend him to anyone. – Ann VERIFIED HOMESTARS.CA REVIEW


“I had someone break into my house and called on a Saturday to have someone assess the damage. Serge showed up the next day and provided a quote and said they could start the job on Monday, so long as the door was in stock. This was extremely important to make sure home was secure, as insurance contractor wasn’t able to fix it for 6-8 weeks! By Tuesday afternoon the repair to the screen door was done. Quality work and professional treatment. Thank you Serge and team for making me me and my family safe.” – Ed VERIFIED HOMESTARS.CA REVIEW


“I found Serge on KIJIJI! What great luck! I had spent months debating whether to replace or repair my 35 year old windows. Serge came right away to look at my windows and was very honest. He thought my windows were very high quality and that replacing them could wait, no sales pressure for new windows. He found this very hard to find part and did the work when he said he would. Quality of work was excellent. Overall Serge was very reliable, professional and honest.” – Lorrie VERIFIED HOMESTARS.CA REVIEW


“We had a front door replaced through Windows Mississauga. Konstanin – the sales person was polite and technically inclined, he knew his product well and offered us a few options how to build in the door. We also tried several companies before Direct came in – their price and quality ratio wasn’t as good as we got it with Windows Mississauga, so we went with them and are happy with the door, life time warranty and the attitude of the workers. We recommend this company for any window and door related jobs.” – Natalia VERIFIED HOMESTARS.CA REVIEW
