WARMINSTER, PENNSYLVANIA -- If you plan on using this company, learn how to accurately measure your own window frames. They sent their "Factory Trained" technician over to measure the openings for customer windows and when they arrived to retrofit the installer had to perform miracles because they were mis-measured. Thankfully they hire talented staff (this particular guy was actually a general contractor doing this for some side work) as he and his helper were the only reason I actually had windows that day. The company doesn't honor their published 100% satisfaction guarantee and the windows, while beautiful and most likely durable (have only had them for 2 weeks) are pricey. If you are going to get replacement windows from Thermal Shield, Warminster-PA, do yourself a favor and double check the technicians measurements. If I had, I would have corner round trim installed in the places were the "Custom" replacement windows didn't fit. I am only luck that they had the general contractor on his day off come do this installation otherwise I would be left with six holes in my house and no recourse.
THIS COMPANY DOES NOT HONOR IT'S GUARANTEE !!!!!!!
Be forewarned because not only is that warranty questionable, they don't return phone calls and also miss appointments with half hearted apologies.
