Hilltop Services of Riderwood

I replaced all my windows and installed two sliding patio doors in my home in 2001; bought the Kensington "Huntington" series windows and patio doors and was very much impressed with the choice until I started to have problems with the patio door de-gassing. The company I purchased them from replaced the door the first time, it has happened again, and now cannot find a replacement door or anyone to replace the degassed door. Paid top dollar for the windows and doors and now I am left with a clouded over patio door and I thought I had a "lifetime warranty"; so much for that thought!
