Our duplex was 40 years old and our fortis bill was significantly high. We finally decided to invest in changing our windows, patio doors and furnace. This was 7 years ago, we had 3 quotations and our best experience was with HSHI. Their price were right in the middle of 3 but it was more the knowledge and honesty of their salesman Brian White. He was very patient with all our questions, he knew what he was talking about and he offered us options to fit our budget. Most importantly, he explained really well about the rebate program and their in house finance program without pressure. This result in Brian also receiving business from the other side owner of our duplex lot! The outcome was so worth it. Our fortis bill decreased by 50%, our whole duplex has new face-lift with the new windows and patio doors installed and we have a very efficient running furnace!
The reason I decided to write them a review after 7 years is because I find their customer service level excellent. Just recently we may have a warranty issue and their customer service remains excellent. It is so important to find a company that treats their existing old customers just like new clients. This being said, we highly recommend HSHI!
