This company was referred to us through a window installer. We found our home drafty and the temperature was plus/minus two degrees from the main floor to our second floor. The window installer suggested we give these guys a call as it would probably be the best bang for our buck (a couple grand to do insulation as opposed to a couple grand for one window). Sure enough, he was right.
This company was extremely pleasant to work with - it's a father-son, family owned & operated business and they do a great job. Very professional and friendly. Explained the process to us from start to finish and spent the day to blow the insulation properly so that it won't shrink over time. I would highly recommend working with these guys...very honest and professional. We also noticed a huge improvement in our comfort level in our home and no longer have the varying temperatures on our top floor.
