I was a little skeptical when the agent who knocked on our door, however I knew my window's needed to be changed within the next 3 years. After hearing what the agent said and explained to us about the windows and gave us a quote, we decided to give Optima Home Improvements a shot after doing a little research online. After some rescheduling due to weather, an army of installers came bright and earlier in the morning of the install. All were polite and very hard working and the job was done in one day. I am very pleased and happy with the quality of work and the quality of windows. They are high quality and I am able to tell a difference, where their were drafty windows are no longer. I have not received my hydro bill to see any difference, but I can tell my furnace is not running as hard. The tint is a nice feature adding privacy so you do require to have your shades down on nice sunny days. My only complaint would be that even though they had drop clothes walking through the house, they did not move the drop clothes around and created quite a mess with their boots on the flooring. But this is understandable for the quality of work and the quickness that they completed it. Chris and Arthur were very friendly and explained the process to me throughout the process and installation. A very happy customer.
