Attic Restoration in Portland, OR
After rodents or squirrels, the attic needs more than a trap. We clean it out, sanitize it and put it back in working order.
An attic that has hosted rodents or squirrels holds droppings, urine, nesting material and often dead animals, all of it worked into the insulation. Those materials carry bacteria, parasites and odors, and they can reach living spaces through ceiling fixtures and air leaks.
Restoration is the step that returns the attic to a clean, efficient state. It is also what makes the exclusion work last, because lingering scent trails and nesting material tell new animals that the space is already a good home.
Assessment first
We inspect the whole attic: the extent of contamination, the condition of wiring and ducts, signs of moisture, and any gaps in the roof deck or soffits that let animals in. You get a clear picture of what needs to be done and why, before work begins.
Removal and sanitizing
Crews wear protective gear and use HEPA-rated vacuums to remove soiled insulation and debris. Surfaces are then treated with an enzymatic or disinfectant product to neutralize odors and reduce pathogens. This is the part that is hard and unsafe to do yourself.
Rebuilding the attic
New insulation restores comfort and efficiency, and we can install insulation designed to resist insects. We also repair or protect ducts and wiring and close the gaps that animals used. Details on the insulation itself are on our attic insulation page.
What to watch for
Health and air quality
Contaminated insulation can circulate allergens and pathogens through the home.
Energy efficiency
Matted, soiled insulation stops insulating, and heating and cooling cost more.
Preventing a repeat
Clean, sealed attics are less attractive to the next animal.
