Photo Album: Remediation & Insulation in Farmington Hills, MI
The homeowner explained that they had a critter problem in their attic and mice have made a mess inside the attic with droppings and urine. The basement floor was contaminated with mouse droppings and they wouldn't let their kids go downstairs because of it. The problem was caused by access points in the attic where the flashing against the gable walls was separated allowing mice to easily enter the attic. Holes were also present in the rim joist around the piping to the outside that allowed mice to get into the basement and nest in the fiberglass batt. Our solution was to remove all of the fiberglass batt insulation from the attic floor, Vacuum the entire attic floor to get rid of all of the mice droppings and start with a clean surface. We then treated the entire attic with a disinfectant to clean and remove the odor of urine. We closed the gaps in the flashing with screws and then sealed the flashing along the gable wall with a roofing caulk. We used a combination of products to achieve our solution. We used Mold X2 products for disinfection. Roofing caulk and screws for sealing flashing on gable walls, 7/16" OSB for covering the ceiling drop soffits, metal flashing, fire caulk, metal wire, Ez roll rock wool sleeve, 1/2" Foam board, SilverGlo, weather-stripping, adhesive, DuroVent rafter vents (4'x22" and 6'x22"), 14" TruSoft Cellulose or R49, Zyp Kit 2 part Foam Kit, 205 board ft. The homeowner now has a healthy clean attic that has been insulated to an Energy Star Rating R49 and all of the gaps that were allowing pests to enter the attic have been closed off.
