i am the owner of complete carpet care this is not a franchise i am passionate about what i do, i always give the best advice to my customers if i think i can't get a result i will tell you.I use a deep pile dirt extraction system and drying time depending on pile depth is about 2 to 4 hours (deodorising and anti bacterial treatment is free in all my cleaning this will kill dust mite carpet mites and many other nasties ) rooms start at £30 and hall st landings from £35 there are always discounts for multiple areas and full houses. I also do dupont teflon coatings (carpet protection) and anti viral treatment at a reasonable cost (please feel free to ask for a free quotation)
