We purchased a Groupon voucher for a simple caulk repair from Super Surface. The gentleman that came out to repair our caulk was so friendly and knowledgeable. He repair the bathtub caulk and even resealed my bathroom window for no charge at all. He came out one week later to refinish my bathtub in another bathroom in our house. It looks amazing. Bright white and brand new . I would recommended the guys at Super Surface to anyone I know.
