Soft surfaces such as carpet, upholstery and drapery are our biggest air filters. Having those things professionally cleaned will allow them to continue to do their job of filtering the air. Zerorez cleans every surface from top to bottom. Be sure to take advantage of their Special Offer: Get your carpets cleaned for “as low as” $35 per room, plus receive a free tile cleaning (100 sq ft). *Minimums apply.
