Cold Craft was the most experienced professional contractor I have ever worked with. From start to finish, they excelled in every aspect. When Robert intially came out to discuss the project, he spent an hour and a half explaining things to me and answering every possible question I could possibly come up with.Another plus was that they are Diamond Certified -- a rating they highly deserve.They finished the job on time and when they cleaned up I couldn't tell they had been there because they cleaned up so well. When I had to reroute one pvc pipe, they came out quickly and made the adjustment. With their 18 month buy back program, how can you go wrong? After they installed my high energy efficient furnace, the therms on my utility bill dropped from 137 to 84 a month.
