We had all our 30 yr, old windows replaced over 1 yr. ago and we couldn't be happier with them!!!!…read moreThe old windows would frost up in the winter, you couldn't touch the glass it was so could, the wood was rotting , Now they aren't doing any of that ! Our house is so much warmer in the winter and cooler in the summer! We use our furnace an air conditioners so much less. They were on the low end of the price range but top end on quality and service! The installation was quick, and clean! They look beautiful! We had a bit of a snag with an odd shaped window but they handled it appropriately for us! You can't get better quality at any price! HIGHLY a recommend them!!!

He also took the time to help me find the entry door that would work perfectly for our house. Dan is very conscientious, fair priced and did a beautiful job.

Based on the reviews he read here on Yelp he decided to go with Alt Builders and their owner Dan. He contacted Dan and was who responded very promptly on a Sunday afternoon. Dan came out the next day to size up the job. He was prompt and very knowledgeable about what Jeff was looking to have done. The patio door was ordered and came in approximately 3 weeks later. Dan and his crew were able to come out to do the job within a couple of days and completed the job in a day and a half just like he promised. They cleaned up and the installation went smoothly. The price was very reasonable and Jeff is definitely going to hire Alt Builders in the future to get some doors installed. He highly recommends Dan for any work or repairs you might need.

Fantastic company to work with, great customer service to make sure the details are done correctly…read more We have done THREE projects with FiberTech because of the quality of craftmanship and longevity of their windows and doors. We highly recommend these windows and doors if you don't enjoy replacing every ten years.

Living in Northern Ontario, we searched for the best option during our extensive house remodel to…read moreget the best windows out there with consideration of durability and energy efficiency. We have some big/huge windows, and considered wood, vinyl, and fiberglass. We dove deep into the NRCAN ratings of window suppliers, and Fibertec checked off all the boxes (being a Canadian Company was a bonus). The windows all installed well and the house is warm and cozy with no condensation on the inside of these triple paned windows. Overall, these windows were an amazing choice and have held up well. Fibreglass (with glass in the name) expands and contracts at a similar rate to the glass panes themselves, so we do not regret our choice! At about the 13-to 14-year mark, we experienced some failures of the seals within approximately 60% of the windows. The first sign is frost between the panes (in the corners) on the coldest winter days (say -20C or lower). In another year, the low-E coating begins to break down, becoming patchy and noticeable. The initial 15-year warranty paid off, as Fibertech has a solid process in place for honouring their warranty and shipping new panes for replacement. The replacement panes are all built with super spacer technology, which is designed to prevent the problem of failing seals. We have new warranties on the new panes and are only 2 years in with no problems noted.

Save your money and go elsewhere . I've owned plenty of doors in my life but never had problems…read morelike the ones from Dans discount windows and doors. Within less than one year from having a new front door installed by Dans, it's been nothing but problems . The wood around the striker broke shortly after install, I called them and they talk to you like you've never used a door before , they put all the blame on us for being too aggressive opening and closing the door and the project manager constantly had to leave multiple times for personal problems (which has nothing to do with the customer- we all have problems in life) ) - all this with a lifetime warranty on the door, which they point out when purchasing but they don't honour it. The hardware on the door never stays tight so every month I've have to re tighten all the hardware (which is absurd ) and they said they would try to fix the broken wood by the striker but they never return your call or show up - I'll be replacing this door before it's even 3 years old because I'm sick of the maintenance required to just keep it operational . Worst customer service I've ever had . Save your money and buy elsewhere. Buyer beware I only gave one star because I couldn't give zero stars
