The first thing to look for in a company is experience. Some of the problems that we frequently see when proper steps are not taken are strong odors from over soaked carpet, bubbling of the carpet that does not recede within 48 hours, rapid re-soiling of olefin carpet, damaged furniture from lack of protection and inconsistent cleaning results. Many manufacturers are now requiring companies to be IICRC certified firms for warranty to stay in place.
Why wont any carpet cleaner suffice?
Commercial buildings & carpet construction vary drastically from residential homes in Maine. If a building or floor is completely carpeted after the carpet cleaning is performed there is a tremendous amount of water vapor added to the air. This water & vapor needs to be controlled and minimized to prevent odors, damage, slip hazards, & mold. The first and most important factor is the training of the technician. A properly trained and qualified technician can use almost any equipment and achieve great results. An improperly trained technician can use the best equipment and get very poor results.
What must a carpet cleaner know about commercial carpet?
The next issue is chemistry and fiber identification. They need to understand the requirements of the textile (PH, drying requirements, properties & temperature limits) and limitations of the carpet cleaning agent. We have seen thousands of dollars of commercial carpet ruined by well intentioned companies. Most commercial carpeting is olefin & or nylon, often a low pile (indoor outdoor style) berber construction. These are pretty forgiving fibers to clean when cleaned properly. However there are many challenges for the cleaning technician. A higher PH cleaning agent is often needed to clean commercial carpets due to the type of soiling and its ability to stick to oily soils.
What criteria should they meet?
A commercial carpet cleaning company in Maine should have at least 1 million in general liability insurance, should be an IICRC certified firm and should offer free spot removal if spots return. The Better Business Bureau & Angie's list are a good resource to find a good contractor. You should ask the contractor for their IICRC card and find out how they plan on handling your unique cleaning needs. Our company Octagon Cleaning & Restoration can provide a free estimate if you are in Southern or Central Maine.
