Healthy Home Restoration sealed my crawlspace and cellar, and I couldn't be happier with the results. Dennis and Ruth **** at HHR are knowledgeable, professional, and reliable. Their jobsite manager, Jiovanni, and his work crew are skilled and did a very thorough job. I had horrific mold and dust problems in my crawlspace which I tried to address myself with ventilation, a dehumidifier, and outdoor drains, but my results were ineffective at best. During moderate to heavy rains, our cellar would have flooded if not for the heroic efforts of my aging sump pump, and the crawlspace would become a muddy pit from water leaking in through the foundation. The living areas in the house would smell musty for days after. Dennis assessed the problem, and I opted for almost every service on their list (see below). The four workers put in eight solid days of hand scrubbing, digging, and nailing with fantastic results. All the areas under the house are now clean, dry, and bug free. I can now store stuff in my cellar and crawlspace. I also bought the best air purifier I could find for our living space, and our measured indoor air quality is now excellent compared to the previous very poor rating. The work was not cheap, but I'm very pleased with the results.
