In November of 2014 I was looking for a company to do quality carpet cleaning in our home. I had researched the best type of cleaning, read reviews, talked to the Mohawk carpet company and finally decided on Hammond Knoll. It was very important to me that the company use the correct chemical balance to ensure there was no residue left behind to attract dirt, and important that they take care of my home while here. There was an error in the initial estimate (they apparently quoted the price for wool carpets) but other than that, the experience was a positive one. Scott was my technician and he was great. He knew I wanted quality work and I believe he did his best to ensure I was satisfied. I didn't feel as though he was rushing through as quickly as possible, but was taking time to make sure the job was done right. He protected the wood trim corners and was respectful of our home. The carpets looked great and dried quickly. We didn't have traffic areas or spots so I can't comment on how effective the cleaning would have been on highly soiled areas, but for my routine cleaning they did a great job and I'll use them again.
