We were doing a number of energy related upgrades to our house last year, while working towards some rebates from Union Gas. We met with Serge and signed a deal for three steel entry doors, a glass patio door and a small window. The measurements revealed that the patio door would be more expensive than initially projected, but we agreed to this and the installation was done as scheduled. The installation was fairly painless. There was some small issues and the installers came back two weeks later to fix those up. It has now been over three months and everything has held up fine. Our major issue came in regards to that energy audit, we had a real hard time trying to get the Energy Star rating stickers from Ecotech for the doors that were installed. A runaround of over two months of Ecotech office staff ignoring emails, phone calls and phone messages, until finally a manager called us back and offered to just refund the rebate amount that those stickers were worth to us. We never did get the stickers but were overall satisfied to put the matter to rest. Again, everything went fairly well with the product and the install, but the following experience with the office staff was very poor. I imagine that chasing up a warranty or a complaint would be brutal.
