replacement of windows

The windows in my home were replaced by Supreme Windows. The installers were courteous and went about their job without delay and finished in a timely manor.
The windows themselves I was very disappointed in. The frames did not met up (gaps from one piece to the next), there are pieces of the frames that are not flush and stick out. A staff member did come out to check the frames and he said that all the windows from the shop come like that with the sharp edges, gaps where pieces do not meet, it is normal. He did agree to fill the gaps with a filler when I still indicated that I did not like how they were.

Hi Karl,
I always appreciate the responsiveness you provide to our requests for quotation. I’m often put in a position where I’m asked to provide our decision makers with cost estimates with very short turnaround times and every time I've called upon you for support you've come through. I applaud your approach to customer service and every time you come through with numbers for us I ensure that our leaders know what kind of an effort you and your organization put forward to meet our needs (i.e. completing and sending quotes in the late hours of a day or shuffling other jobs around so that one of ours can be completed by a fixed date). Your installation crews also need to be applauded as they are often asked to work in and among our residents and their personal belongings and they never complain, never leave a mess behind, and many of our representatives cannot believe how efficient they are at what they do.

As the Manager of Bethany Care Society’s Materiel Management department I don’t just look for someone that can supply what we need at a given price, I look for partnerships and I feel like your company treats Bethany like a partner and not just another customer.

Thank you and your company for all your continued support of Bethany Care Society.
I wish you and your family all the best through the holidays and in the New Year.

Good Morning Karl,
I can't say enough good things about the job your installers did on installing new garage windows for us. They arrived on time, did a fantastic job and cleaned everything up when finished. I noticed the difference almost immediately in the garage temperature when a friend brought his car over for repairs. Instead of taking an several hours or more to bring the garage heat up to a comfortable temperature, it took less than an hour and before long, the coats came off. it was particularly nice to be able to open the windows and rid the garage of diesel exhaust. You may recall one window was to be mounted slightly differently from the one it replaced to keep the tops of all the windows in alignment. Your measurements were dead on. I had a piece of stained wood ready for the installers and as you can see by the photo, the window was a perfect fit.

Thanks again Karl for another well done job. All the best to you and your family at Supreme Windows.

Hi Karl,
Thanks for the note.
Best wishes to you and your family over the holiday season too!

I wanted to say thank you again for all your hard work in getting our new windows and door measured and installed. I understand how busy you are and you always impress us with your hard work, professionalism, expertise, and friendliness. We will definitely call on you again when we need you, and we continue to refer you to our friends and family.

I wanted to let you know how well our new windows and doors are doing:
We replaced all of our North-facing windows, and some South-facing windows, with your triple-pane Low-E windows. Let me tell you how incredible they are! The difference in 2-pane vs the triple pane is serious business! With the triple-pane windows, there is zero condensation inside the windows, even over the past couple of weeks when Calgary temperatures were hitting -30C for many days in a row. There is zero draft coming through, and the clarity of the glass is fantastic. We replaced the windows with the correct product, and we thank you for recommending them. The crews that came were efficient, courteous, cleaned appropriately, and answered all questions.

The new back door is great too. Your crew came to our house, removed the old door and frame, installed and sealed a new door frame and all, quickly and efficiently. After they were gone, as was the case with the window crews, there was no mess for us to clean. A huge help when there are little kids running around!

We highly recommend the triple-pane Low-E windows to anyone thinking of replacing their windows, especially in Calgary's climate.

We are looking forward to working with you again when we decide to replace the rest of our windows!

Thanks again.
Happy Holidays!

Hi Karl,

Thank you for the Christmas email.
Yes, during this latest cold snap I have to say our new windows kept the house warmer than I have ever experienced in my life! The difference from the old storm windows to the new Triple Low E was amazing.
Merry Christmas to you and your family!

I love my new doors as when it was cold I did not feel cold air seeping in around the edges. The French patio door is such a strong door ... Front door is beautiful especially where the glass is and with Christmas lights outside as they reflect in the glass and create such a beautiful effect. I sometimes just stand there and look at it because it is like looking into a kaleidoscope.

The house feels cozy at this temp but at higher temps still chilly ... That is not to say I am not happy with my purchase ... I am. Love my windows and doors. Of all the work I had done in 2013, the windows were the least disruptive and problematic. Wonderful crew working on my remodel.

Best wishes for a Merry Christmas and a healthy and happy 2014 with more successes.

Regards, Karen

Good morning Karl,

Thank you for the Christmas letter. I’ve been meaning to email you to let you know that I am extremely happy with my new doors and was hoping that we could meet again as I would like to replace all the windows in my walkout bungalow. I would like to go with triple pain, low E windows.

Thanks Karl for the Season’s Greetings. Yes I am very happy with the way our windows performed during the cold spell, I kept checking them to see if they were worth the money and they were.

We will call you in the New Year to set up a time to replace the last windows,i will call to set up the time to have this done.

Merry Christmas and all the best in 2014 to you and your family.

Windows

Personally, I am extremely dissatisfied with Supreme windows. Our home is 5 years old. The first 3 winters the windows seemed great. In fact, I was extremely impressed that there was absolutely no condensation at even -30 C. Then last winter, at even -10 C I noticed some condensation on all the windows. At -25 like it is now, there is an inch of ice along the bottom of all of them.

I called Supreme last winter and the service depths extremely rude. I was basically told there is nothing wrong with the windows and the humidity is too high in my house. When I asked what it should be, they could not provide an answer. Here's the thing - the humidity is exactly the same as the first 3 winters. I know this because I have been watching it very closely. We have extensive amount of hardwood flooring on our main floor and the hardwood manufacturer requires an minimum of 30% to avoid cracking. The crappy little humidifier on the furnace can't get it much above 23 or 24%. I have the exact same furnace, humidifier and humidity meter and its always been between 21 and 23%. There is no way there should be condensation and -10 C outside with 23% hum its inside, unless the windows have virtually no insulating value.

I really have no idea what has gone wrong with these windows. I do know Supreme has no interest in helping me.

I will never buy any product from Supreme again!

Company Response

Hello George,
It is very unfortunate that your home had been fitted with double pane windows in the builder series frame given your expectations for humidity levels in your home. They function according to the laws of physics in the same manner that all things do. I would like for not only yourself but every home owner to understand that R value and performance ratings have a very real relevance with regards to exterior temperatures, interior home temperatures/humidity levels and glass insulating properties. There are various levels and grades of windows and doors that we manufacture, yours being considered a builder grade type window meets the basic demands of the industry, will meet minimum code requirements, but should not be confused with our higher performance products. By contrast our Triple glazed Low E Argon gas filled windows (or Legacy Series Windows) would be considered a high performance window product. The difference is substantial between these two types of products whether it is very cold or very hot outside as they reflect 2 1/2 times more heat from entering your home or leaving it. When we talk about glass surface temperatures and how this functions with regards to moisture showing up on the glass is simple. The colder the glass surface the faster a dew point will be reached (think of a glass of water pulled out of a fridge - condensation forms immediately as the cool glass surface relative to the rooms ambient temperature and humidity level is expressed almost instantly) With a double pane glass window and by having an internal humidity level at or above 30% in your home, will virtually guarantee that window to reach a dew point even when exterior temperatures are around -10 C (given the maximum possible R value that type of window can provide) There is nothing wrong with your window it is performing to the best of it's ability, this much is true. What is also true is that with your type of window (double pane basic standard issue builder series product) we highly recommend that any temperature below -10 you must begin equalization of your homes internal humidity percentage in 5% per 5 degree drop increments. So when we have -20 or -25 degree C weather your humidity must not be higher than 15% or you are guaranteed to have a dew point (condensation) form on a double pane glass unit. Again this is just nature at work. If you reduce your homes humidity during a cold snap it will save you a great deal of aggravation. Another suggestion that works well if we get a sudden cold snap is to turn on your Kitchen hood fan or bathroom fan that vents outside as this will aid in equalizing the humidity and internal pressure of your home thereby greatly reducing condensation issues. If you have a high performance window system (and I have both double pane and Triple pane Low E Argon gas filled windows in my own home) internal humidity levels are not a concern with my Triple Low E windows but humidity has massive effects on my double pane windows. Double pane windows simply conduct more as they have a lower insulating value. I have a high performance Triple glazed Low E Argon gas filled window in a new steam shower I installed this past Summer and even with +100 C steam against the window this past week when temperatures were reaching -28 C I did not have any frost or ice on the window and when the shower area had dried out there was no condensation on the glass at all. However my double pane windows have shown signs of moisture all week (again given interior humidity versus exterior temperatures). So the very clear moral of the story that I cannot express enough is for everyone considering new windows, whether you are building a home or replacing windows is this - please save yourself the grief, spend the small difference in price between the basic offering and higher end products - especially if your expectations are to have high levels of humidity in your homes during our extreme winter temperatures. You will not believe the difference.
