I found Spectrum Cleaning and Restoration through an ad online. I hired them to come clean a rental property's carpet. They did an excellent job and I was very happy with their work. We had a previous company come out to clean the carpet but a coffee stain that was below the carpet on the floor came through within a few months because of their methods of heavy duty cleaning. Spectrum Cleaning and Restoration used a dry cleaning and minimal moisture apporach and the stain came right out.
The workmen were pleasant, cooperative and thorough. The company came back to follow up and were attentive and friendly. I've looked around a bit and this company has been the best I've found so far. Their pricing is fair and they met all my needs for this job.
