Window Replacements
I’ve used Platinum 3 times over the last 10 years to replace windows in our house as and when they reach the end of their useful life. From experience, I know I can trust Platinum to deliver a quality window (with a lifetime warranty), on-time and at a reasonable cost. Everyone that I dealt with at Platinum is friendly, knowledgeable, responsive and professional. They clearly take pride in their work and in ensuring customer satisfaction. I would not go anywhere else for my windows.
– Leslie in Thornhill
Windows and Front Door
The workmanship was excellent. The installers were very thorough and professional in their work. After looking at a couple of companies, we picked Platinum because the price was very reasonable, and because of the guarantee of the work and materials. Jim and Maggie were very helpful. It was nice to see that Gus dropped by to make sure everything was ok with us. I would highly recommend them.
– Fred in East York
Front Doors
Excellent service from sales through to installation. We had two sets of double door fibre glass installations at the front of the house. High-quality doors with amazing curb appeal! Scott our salesperson was highly knowledgeable and spent the time going through our options with materials and the pros and cons. Scott came to our house to see where the doors would be required and we also met him in the showroom to get a better feel of the finished products. The installers were courteous and kept the work area clean from beginning to end. Highly recommend this company for high-quality exterior doors.
– Sukitaur in Toronto
Windows And Patio Door Replacement
Maggie and Maryanna at Platinum are very friendly and professional. The GreenOn rebate program deadline was something I was concerned about, but they did the job in time. Harris, the installer, was quite thorough and friendly. They replaced the windows on time and I am very happy. I would recommend them if someone is looking for windows.
– Pravin in Markham
Windows
Excellent customer service and product. Maggie Vlahos we very helpful in the entire process, answering all the call and concerns. The installers were very professional and did a good job, even the cleanup was really good. The entire process from sales to installation was very smooth. Windows are not changed every year, and when you do it make sure you make the right choice, my house in Pickering looks 100% new, a big Thank You.
– Norman in Toronto
Replacement Windows
The product is exactly what we wanted, works extremely well and looks great. Installation was amazing as the interior of the house was not changed in any way. When they left they left everything clean and took away all the old materials.
– Paul in Toronto
Custom Doors and Casement Windows
Exceptional product and installation. Great admin staff ....thank you Maggie! Salesperson Ron is no longer there but also treated me with kid gloves. Just got off the phone with Maggie to replace front porch windows next. As a Realtor in Toronto ...Platinum is my one and only referral for Windows and doors. You get what you pay for!
– Belynda in Toronto
Great Work Form Quote To Finish
We were recommended to use Platinum and we weren't disappointed. Right from the quote we received (Scott), to dealing with receptionist and the installation (Edgar), we were VERY impressed. We had a new patio door put in replacing a large window in our kitchen. The work was done fairly quickly and the quality of the workmanship was great. Can't say enough positives about the whole experience dealing with this company and we would certainly recommend them.
– Joe in Pincourt
All Doors, Entire House Windows
Thirty years ago we had to, storm doors installed in our home. It was time to replace them. We kept our bill and found out the company was still in business. We were delighted and immediately phoned. We were greeted by the best receptionist there could be "Maggie". I believe a company begins with that first phone call. You would think Maggie had a piece of the business but ishe does not. The product speaks for itself being the best in the market and are installed by Edgar whose work is perfection. The whole company from start to finish is excellent. You will not be disappointed.
– Karen in Pefferlaw
New Windows
For the second time we got new windows from Platinum and for the second time everything was just right. Jim George talked like a human being rather than a salesman and climbed up to tape the window so I could see what it would look like with panes. Someone popped in a couple of weeks later and politely checked the measurements. The installers came right on time or perhaps a bit early and cheerfully and accurately installed the windows on an extremely hot afternoon. The new kitchen window functions perfectly and is the icing on the cake to our small kitchen renovation..
– Kate in Toronto
New Windows
Two years ago we had all the upstairs windows replaced and were very happy with the whole experience. The new windows made a huge difference especially in the winter and the cost of our heating bill went down. This year we replaced all the downstairs window and especially love the larger living room window to see the backyard. Overall, a great experience from the quotation (with Jim George) to the installation process. Kudos to Edgar and his assistant who were so efficient and tidied up after themselves. Thank you Platinum Windows!!
– Jennifer in Toronto
Casement Windows Installation
We chose to have Platinum install casement windows in our home because the company was highly recommended by one of our neighbours. Edgar, employed by Platinum did a beautiful job! The work proceeded perfectly as scheduled and the workplace was left very tidy. Thank you so much!
– Ron & Karen in Scarborough
Windows and Doors
We have had Platinum work on three projects in our home within the past 5 years and every project has more than pleased us. We have replaced all the windows and completely changed the front of our home with a beautiful new door. The new windows & door keep our home quiet to street noise, improved the interior temperature control and are a breeze to clean. Our installer Hal did a perfect job on all the projects. Four of our neighbours have since chosen Platinum for their homes. The company has met every commitment they made to us . They guided us through our selection without pressure sales tactics and always delivered high quality products on time. We had a tiny service need once and they went above and beyond to please us.
– Nancy and Brian in Toronto
Replaced Windows On 50 Year Old Home
Platinum Windows is the company we trust to replace the windows in our home - bedrooms, dining room and kitchen. The process from start to finish is professional and caring - from receiving the quote, to scheduling the work, to the finished job. We would not hesitate to recommend Platinum Windows for any windows or doors in your home.
– Margaret in Richmond Hill
Living Room Windows
I am very pleased with the installation of new living room windows and others on my house. Mr. Gus George did his outmost best to replace defective windows that were installed 20 years ago at an exceptional low cost. His new windows are far better than the previous ones. The installer did a marvellous job. I would most certainly recommend this company to others.
– Farouk in Scarborough
Kitchen Door And Window Replacement
Fantastic Job with the windows in our bedroom and the sliding door in the kitchen....no sign of draft through the winter and no condensation. Thank you so much, we are going to need other windows replaced in our Great Room and will definitely consider to be done by your company.
– Heather in Whitby
Top Quality Product And Service
We had been having issues with 6 windows and a patio door that had been installed at various times over the last 30 years. There was some fogging, some condensation, and the door was not sliding well any more. We got a very helpful visit from Jim to discuss our needs and options. With good recommendations from a friend and reviews on HomeStars, we signed a contract. Zoran and his crew member came out on the appointed day -- a cold and windy one in December. They worked non-stop throughout the day to ensure that the house temperature stayed reasonable. I can't say enough about dealing with all the people at Platinum. I recommend them most highly. They are now the go-to window company for everyone in our family.
– Dan in Toronto
Windows and Removing Old Siding
The work was done by experts, who where also friendly, and cleaned up after they were done. This was done on a very hot and humid day.
– Maureen in Whitby
Windows and Doors
Great workmanship! The men were very professional and court. Their work was excellent. They cleaned up very well!
– HomeStars User in Toronto
New Windows And Doors
I am very happy with this company, they have replaced a screen door, sliding patio door, front door (high quality) approximately four windows, not all at the same time, over the last three years. Jim is always available and all of the installers (three different crews) do excellent work and are polite, respectful and also offer advice when asked. I have no complaints at all, the products and workmanship and staff are wonderful to deal with. They are reliable, on time (delays due to demand are not unexpected) and have not let me down at all. I miss Maggie's sunshiny voice and Marianne is lovely to talk to as well. Great jobs, well done!

Windows And Doors Replacement
I found Platinum Windows & Doors on the government website and followed up with a call. Maggie was very professional and the leadership engaged with me to answer my questions and work out a deal. Delivery of the windows and doors were delayed due to backlog at the manufacturers - this was handled professional and I was kept in the loop of delays. Once the manufacturing was done, scheduling was superbly handled by Maggie and the site work of changing out the windows were expertly done by the crew.
– HomeStars User in Toronto
Windows Install
From Jim to Maggie to Gus, they were all easy to deal with and extremely fair and reasonably priced. Hal and Desmond did a great job on the install - would recommend them. Thank you.

Storm Door Installation
Platinum has been instrumental over the last few years in helping us upgrade our home with new custom windows and doors. Last Fall, we added a stunning new black front door with side panel to our yellow brick bungalow. This Spring, we added a black storm door with a full glass panel to protect, yet show off the new door. We recommend this company highly to anyone who is planning to replace windows and doors with high-quality products. The outstanding professionalism, customer service, and expertise shown by all staff in instilled by company President, Gus George. With every project, we look forward to seeing expert installer, Hal, at work. Installations happen on time and without fuss ... an absolute pleasure in this day and age of sub-standard customer service!
– Angela & Larry in Scarborough
Replacement Windows
This was the second time we used Platinum since we were so happy with the salesmanship and workmanship done at our home two years ago. We had all the front windows replaced this time and the recommendations for the new windows was on-point. From start to finish, it was a really good experience...professional and clean. The windows look great and we no longer hear any outside noise. We have already recommended Platinum to friends and family.
– HomeStars User in Toronto
Superb Service
I was referred to Platinum by friends when I needed to replace all of the windows and patio door in my new residence. I wanted to get a couple quotes before deciding. Jim was fantastic from the moment I opened the door - personable, professional and objective. I asked for a quote for a new front door. He told me that there was nothing wrong with the door I had and he didn't see a need for me to spend money on that now. (I am considering an upgrade in the near future) Forget the quotes, I signed on the spot! And in the end, their prices were better than the competition - no negotiating required. Tony installed the windows and once again, superb professionalism.
– HomeStars User in Toronto
New Windows
We found Platinum Windows on the Window Wise website as suggested by our Home Energy Inspector. We were very impressed with their product as they were equal, if not better than other high quality products on the market. We were especially happy with the price and timely installation as well as the friendly service. You will not be disappointed by Platinum Windows!

Window, Doors And Sliding Doors In The Entire House
From the moment we stepped into the showroom at Platinum Windows and Doors we felt comfortable and welcome. You showed us the many possible combinations for renovating all our windows and doors. You explained everything clearly and outlined the process to us. We felt fully informed and everything ran to plan...Amazing. The installer was professional, friendly, tireless, and competent. I was impressed with the pride he had in Platinum Windows and the time he took to give us advice and to demonstrate the workings of each window and door. The installer rightfully took pride in his outstanding workmanship.
– T.M. in Toronto
Very Satisfied With The Product And Installation.
I was on a look out for a company who could change the doors and windows of my house. I even attended a few home renovation exhibitions, but couldn't make up my mind. And then I came across Platinum. I like their professionalism. Maggie is very courteous. Jim knows the product in and out. In 2014 I got my backyard door and living room window changed from Platinum and this year in 2016 Platinum changed all the upstairs windows. Excellent work. Hal's work is artistic. I was very pleased with the product and service provided by Platinum. I would surely recommend Platinum to anyone who wants their Windows and Doors changed.
– Shivprasad in Markham
Enclosed Porch
I had my porch enclosed this summer. Hal did the job. He did a fantastic job. This company was the best Reno company I have ever dealt with. No issues just perfection. I wish I knew about it a long time ago. Other Reno companies have a lot to learn from them. Jim Goerge was great too.
– Sarit in Markham

New Windows And Patio Door
Dealt with Jim George who provided excellent information and fair pricing. Windows arrived as scheduled and were installed by Edgar and Ceasar. Very professional. They went about the installation quickly and quietly. They made sure everything was caulked and finished properly. Cleaned up all the debris and removed everything from site. Will recommend Plantium Windows and Doors to all our friends and coworkers and hopefully they will have Edgar and Ceasar do the installation. Job well done.
– Nadine from Vaughan
Window Installation
Platinum replaced all of the windows in my 3-storey townhouse, plus a patio door. Their price was well in line with other estimates, and the service impeccable. They were professional, prompt, and courteous and the entire job was done in two part-days, the first day by one man working alone! Neighbours have actually stopped by to comment on and admire my new windows. I am happy to give Platinum as many stars as this site will support!
– Nan from Toronto

Complete Window Replacement
Ron, Hal, & Maggie of Platinum are amazing ambassadors of this company. They have replaced ALL windows in my 5-split home in Etobicoke nearly 2 years ago, and I have found them professional, thorough, accommodating, and reliable on follow up, emphasis on the last part - how rare is that? I am amazed at installer Hal's attention to detail and superior work ethic. My highest recommendations!
– Paul from Toronto

I first met with Jim George and he came by and gave us a quote. When it was time to install our door, the installer was excellent (Osmo) and he completed the job in two days and cleaned up leaving the house in the same order.
– HomeStars User from Markham
Window Replacement
Platinum windows is a very professional company. Anne and Gus are great to deal with. From contract signing to installation, it was a pleasure. Hal was a great installer. Their new glass is amazing, its self-cleaning and stays pretty clean! We've had the windows in for a year now and they look brand new. The dust/ dirt doesnt seem to settle on them. Great company and great product. Would highly recommend them for window replacement.

Great experience overall. Omar the installer was great. He cleaned up and gave great advice on my molding. Job was done on time and service and quality was great. I would recommend them highly.
– Mary from Scarborough
Windows And Doors
Had Platinum come in to install 3 windows, and build a side entrance to our house (including installation of a new door). Great experience all around. Ron, the sales guy, was great and thorough - followed up on everything and gave me comfort knowing we were taken care of. The installation person (Dave?) was fantastic too - gave great advice and was very careful to make sure we were happy with how everything looked upon delivery. Finally, the people in the office who manages the appointments were very friendly and always helpful. On top of this, the work was done impeccably, and the cost was cheaper than most other contractors I received quotes from.
