My wife and I recently had Energy Star windows installed throughout our house. The company was slightly more expensive then their competition which initially concerned us; however they proved to be a fine choice. They came to our house at our convenience and gave us an estimate and answered all of our questions. I found them to be highly knowledgeable about their products. What I particularly liked was their professionalism. Never once did we feel pressured into anything. On the day of the job, the crew arrived on time and got right to work. Once the job was finished, they did a final walk through with us and opened all the windows and made sure they opened properly. I would highly recommend this company to others looking for window installations!
