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.

Complete Installation Failure and Total Lack of Accountability…read more Do not trust EcoTech Windows and Doors with your home. We purchased exterior doors from them, paid in full, and the result has been a complete nightmare of defective workmanship and zero accountability. The Issues: * Active Water Ingress: Rainwater leaks directly under the frame and pools into our home, creating a serious risk of subfloor and structural damage. * Defective Frame Alignment: The door frame was installed so severely out of plumb that the door physically swings shut completely on its own without intervention. * Omitted Structural Components: EcoTech's own lead technician confirmed in writing that they completely omitted both a sloped sub sill drainage pan and a flashing membrane during installation. The Service: We endured 7 separate service visits. On July 3, 2026, they performed a complete full frame teardown and reinstallation, which somehow made the alignment and water leaks even worse. We acted in good faith the entire time; we even helped jump start their technician's broken down vehicle in our driveway after a visit. When repairs failed, senior management tried to hide behind a fine print handicap sill clause to disclaim responsibility for water ingress on an exterior door, completely ignoring basic implied standards under Ontario's Consumer Protection Act. Senior management ultimately stopped responding altogether once formal settlement demands were made. We are now forced to seek full remediation costs through Ontario Small Claims Court. Save yourself the money, time, and structural damage. Hire a real professional company instead.

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
