We had some installation problems initially due to the age of our house. We were told that they have made some changes for the better in their installations due to the problems encountered on our project. Centennial Windows has rectified the problems. The job foreman, Don Rigby, went above and beyond trying to ensure the job was done to our satisfaction. It's obvious how much this company means to him. Very professional, very proud. May seem a bit pricey, but you get what you pay for, and here, it is TOP QUALITY. I would highly recommend Centennial Windows.

We've had Centennial replace 4 windows over the last 2 years. They are fairly pricey but I have never regretted purchasing my windows from Centennial because the quality of the windows provides a comfortable indoor climate and peace of mind that, to me, is priceless. I've referred family as well and they are pleased too.

We had 17 windows installed in our home by Centennial Windows. I would highly recommend them. They were amazing and they went above and beyond the level of service that I expected. You could tell that they were expert installers and they cared! They treated my home with care and made sure that the windows were installed properly. The windows look great and function well. We had an issue in our largest window that's 10 feet by 8 feet. We had some decorative brass pieces installed within the glass and when a train would go by it would rattle slightly. When we asked Centennial what they could do about this, they commented that they could put an extra piece of bevelled glass in the middle to help support the brass pieces. This solved the problem and Centennial considered this a warranty issue because they didn't expect us as homeowners to know that this could happen. Peace of mind!

We had our windows replaced in the summer by Centennial Windows the salesman was from Brantford sales office and the crew was from London. We are 100% satisfied with the product, they fit perfectly, work as designed and were installed also perfectly. The finish work could not be better. After seeing how well the windows were installed we had Centennial come back and replace the front door that we had another company replace several years ago. Yes, the windows were more expensive than having your local window home reno guy do the job, but it is well worth it if you plan to stay in the home for the long term. Centennial gives you names of other customers to speak with. We did this and they were happy to show us their windows. We replaced all the windows in our house, but if this is not possible for you, I would recommend replacing them over a two or three year period. You will satisfied, I just know it!

I used Centennial because my father, a very handy guy, was a big fan of their product. They have won national Energy Star awards for their self-manufactured product and they have an unlimited warrenty on their products for the lifetime of your home (even for new owners if sold). Their sales staff was informative and helpful, even making a second trip to change an order at my request. "Don't pay for 6 months" financing was arranged without question and the install was quickly booked. The installation workers were professional, tidy and quick. Even more significantly, my father had noticed an air leak around one of his 5 year old windows after an EcoHome audit. He called them and they came out quickly and spent 3 hours checking all the windows and repairing the affected one at no charge. They even sent him a $100 check after learning he referred me! So - bottom line is the windows cost more than anyone elses. I was kicking myself for spending that much money but in the end they are totally worry free and for my family that is probably worth the cost.
