I accidently put a hole in the original thermal units to our house that were installed in 1982. After trying the usual big box stores and finding that they either didn't even know what I was talking about or suggested I buy a whole new door unit I went to Pilkey Glass company. I was greeted by Lauren who knew what we wanted and showed us samples to choose from, her advice was greatly appreciated. The two installers came out and took out the old panels and put the new units in with care. The workers were very professional and cleaned the area as they went along, even tidying the pavement outside . The units are amazing and change the exterior and interior look of the house....bonus all around.
