Nivaldo did several jobs at my home in Stow during 2008 and 2009. The largest of these involved removal of wet and moldy insulation from my attic roof rafters and treatment of the sheathing with bleach. Nivaldo installed ceramic tile along the top of one of my tub enclosures, and he also attached heating cables to part of my roof. All the work was done in a professional manner. Nivaldo arrived when he said he would. He was very reliable and conscientious.
