I am not in the habit of endorsing contractors or contractor referral services, but I do like to make the public aware that they exist. I recently had a problem with a garbage disposal and contacted servicemagic.com. They responded with the names of three contractors in my area and I could read reviews of their services online. At least one or two called me right away. As it happens, I solved the problem myself, but I was impressed by how organized and efficient they are.
A potential client had a similar experience with servicemagic when looking for aluminum siding and roofing contractors. They responded quickly and he was pleased with the service. I am going to follow their website and review their advice from time to time, but so far, I am happy to report that customers have been satisfied.
