"Our original siding was 34 years old. They stripped it off in a few hours and replaced it with perfectly installed James Hardie fiber cement siding and trim. We now have a brand new house! Ernest and everyone we had contact with from GS were very patient, service oriented, and concerned for our satisfaction. We would recommend them unconditionally."
