Dutch's mold crew were thorough, professional and responsive in cleaning out our partially finished basement. We had mold growing behind the finished walls that had escaped into the basement and was beginning to give us allergies, and they removed everything in the basement that could harbor spores or be hiding mold (carpet, siding, drywall, insulation) and cleaned what was left. Other contractors had suggested removing only the siding etc in the finished half of the basement, and had quoted a lower price, but I was glad after the fact we had gone with Dutch's more thorough removal as there was mold beginning to grow in hard-to-reach spots throughout the basement, and in some of the insulation around the rim joist. They also were the only contractor we talked to who put an air filter inside the living space as an extra precaution, in addition to filtering the basement air and cleaning everything with HEPA vacs before sanitizing. The crew took a long time going over things with us after the work was done, including pointing out non-mold -related issues like wiring they had capped off after removing fixtures and a weakened structural support beam they uncovered. We had a follow-up concern a little after the project was done, and they came right back to check on it and go over the situation with us. It wasn't a project we wanted to have to do, but it was reassuring to work with this company.
