Very Competitive Pricing
“Windows are a great investment in your home, but not really as exciting as something like a kitchen or bathroom. Still, getting a great product with a good price and exceptional service is very important. As experienced window buyers (this is our third home, and in each we have needed to replace window and door systems), we couldn't be more pleased with TrueSeal Windows. After getting 4 other quotes, we chose Deb from TrueSeal. She took her time in assessing our needs and made a great suggestion for us to try awning windows instead of the casements we had been considering. TrueSeal is a family business with very competitive pricing and a great product. Their warranty on the windows (made by VinylBilt) and installation/craftsmanship can't be beat. Ian did the installation and was thorough, precise, and a pleasure to work with. From start to finish, we would recommend TrueSeal to anyone in the market for windows.”

All Work Was Done on Time
“Excellent work from Deb in the office to Ian and Ryan’s work onsite. Communication was flawless, especially when they needed to alter some of the plans. All work was done on time and done as though they were working on their own house. We are now proud of our "new looking" house with our siding looking impeccable. We would highly recommend this family run business in Brampton.”

Work Is Impeccable
“I have no words to explain how happy we are with the work that John that installer did. The work is impeccable. He was kind and professional. We are truly happy with the windows themselves and the excellent work.”
- Natalle on HomeStars
Good Experience
“We were looking for a solution to replacing the original 32 inch door with sidelight with something that would provide more light. It was difficult to get something we liked as door sizes had changed and nothing seemed to work. Deb suggested a larger door with no sidelight might work. Luckily we had just the right size opening for a 42" door and we chose a full glass panel insert. Arthur did the installation in record time with beautiful results. All in all it was a good experience. Thanks TrueSeal and Arthur.”

Replacement of Windows and Doors
“We replaced all our windows, the front door and garage doors. During the selection and decision making process the TrueSeal team was extremely helpful. Deb took the time to understand our vision as well as offer very helpful options and suggestions. The installers were friendly, very knowledgeable and did a very professional install (including the attention to detail on the finishing work). We are very happy with the end results and would recommend TrueSeal to family and friends without hesitation.”
- Dan on HomeStars
Will Definitely Call Them Back
“I'm very pleased with the quality and workmanship. John and staff are very professional. They did not take any shortcuts. He made sure it was done properly. Would recommend them to anyone and I will. I have other windows and doors that will need to be replaced soon and I will definitely call them back. Thank you.”

Workmanship Was Superb
“The front living room picture window was replaced with a lovely bay window, which we were able to put a small cushion into for our dogs to enjoy the view. The small dining room window was enlarged and replaced with a floor to ceiling bay window so that we could enjoy looking out into the backyard. The family room picture window was also enlarged and replaced with a bay window. All of the bedroom windows were enlarged as well to allow more light. Bathroom, kitchen and basement windows were also replaced. Our family room walkout door to the deck was replaced with a beautiful French door that complimented the new bay window.
I would like to add that the workmanship was superb. It was a pleasure working with the salesperson and the installers, and at no time was there any stress about the timing of the job. After living in this home for over 20 years, I have never had such an easy experience with a home reno, and I would definitely highly recommend their product and service.”
- Suzanne T. on HomeStars
Windows and Doors Replaced at Multiple Properties
“I have used TrueSeal for over 15 years for both windows and doors and have to say the service and quality of the work done is excellent. At my current home TrueSeal has replaced multiple doors and windows and I am very happy with the look and quality of both. The installation teams are very professional and accommodating and when the work is done, they ensure everything is left clean and tidy. The sales team is very knowledgeable and ensures you are getting the right product. I have and would recommend this company to anyone.”
- Walinda M. on HomeStars
Patio Doors and Entry Door Installation
“TrueSeal installed 2 patio doors in 2016. I was so impressed with their knowledge, quality service and professionalism that I also purchased a new entry door in 2017. Deb knows how to make a house a home with her suggestions and attention to detail. I sourced many companies. TrueSeal had the best prices and excellent products. Highly recommend!”

Happy With Our New Windows and Doors`
“Great work, highly experienced installer. Installers made sure we were satisfied with every step of the installation. No mess left behind, everything was as we expected, neat and tidy. Before leaving for the day the installers made sure everything was clean and nothing left out around the property to inconvenience us. This was our first major renovation and TrueSeal eased our worries about any doubts and "contractor horror stories" that we hear so much about.
We could not be happier with our new windows and doors, we notice the outside noise has dramatically decreased and our house stays noticeably cooler, especially upstairs. We hope to have the same increase in comfort in the colder months ahead.
We would definitely use TrueSeal for our next replacement windows and doors, and recommend them to our family and friends. Thanks to the crew, John, Christina, Kim, and Deb who made this such an enjoyable experience for us.”
- Stacey on HomeStars
Terrific Value for Money
“We had TrueSeal replace many of the windows within our home. The sales and installation staff were helpful, courteous and professional. I felt that we got terrific value for our money. Installation also required some minor re-framing as we live in a 100 year old home and not everything is square! TrueSeal did a perfect job on the window installation. I would highly recommend them to friends and family and anyone reading this review.”
- Alice B. on HomeStars
Pleased with New windows and New Sliding Patio Door
“We sincerely thank TrueSeal for the marvelous work they did on our home over the last 2 years. We were so pleased last year with the new windows as well as a new sliding patio door (complete with the mini blinds between the glass) TrueSeal installed. Amazing work!
True Seal just finished installing new vinyl siding with one inch foam underneath. What a difference this makes. It is so much quieter inside our home, not to mention saving on the heat and air conditioning. We are so thankful to Deb and Kim for assisting us in picking out just the perfect shade of vinyl to complement our bricks. They also suggested installing it vertical rather than horizontal and it looks awesome.
We can’t thank John and Gary enough for the time and energy they showed us in getting the job done. A Fantastic job!
TrueSeal has our vote. Have a great day!”
- Rob and Bev on HomeStars

They Stand Behind Their Services
“We have been dealing with TrueSeal for a number of years now on different projects and the products and workmanship are outstanding! I would recommend their services to anyone and am quite confident they would be satisfied with the end result. Also, they stand behind their services and resolve all inquiries quickly and efficiently.”

Extremely Happy With the Final Result
“We can't say enough to praise the job done by Ian and Stacy on our home. The windows you ordered Deb were absolutely fantastic. They look incredible. The whole job was 110% professional from beginning to end. From the moment we spoke we knew this was the right company to do business with. Ian and Stacy were so careful and caring making sure everything was perfect right to the end of the job. We are extremely happy with the final result. When the time comes to match the back of the home with the front we will definitely be calling on your company to finish the job. We would HIGHLY recommend anyone wanting to have new windows installed should only go with TrueSeal. Thanks for such a great job.”
