I contacted GLGC through Homestars's request for quote system. I immediately got a friendly response from the company, and they were very quick in getting me a quote. The quote was reasonable, and the company (especially the receptionist Hally) was very easy to deal with over the phone and through email - ie. easy to contact, and no pressuring from their end. They were patient, and listened to what I wanted (cleaning grout, removing mold, re-caulking, and upholstery cleaning), and were prompt in getting the work done within a few days. No hidden surprises or costs. It's a bit early to tell if the work (caulking) will hold up for the long term, since it has only been a day, but it seems to have been done properly. I would definitely use them again, and would recommend them to my friends and family.
