Remove contaminated insulation and droppings, sanitize, and re-insulate once the house is sealed.
Animals compact insulation, tunnel through it and use it as a toilet. Soiled insulation stops working and holds odour. We bag and remove the affected insulation with a HEPA vacuum, collect droppings, and treat the area with a disinfectant.
Once the attic is clean we top up or replace insulation and fix chewed vapour barrier, ducting and wiring insulation found along the way. Damaged wiring is flagged for an electrician.
Prevention work covers chimney caps, screened roof and gable vents, and metal flashing at roof joints. It can be done on a house that has never had animals, which costs less than a removal.
One-way door on the entry hole, heavy-gauge screening on vents and roof edges, and a check for kits before anything is sealed.
Find the chewed gaps, install a one-way door, and seal the roof line so squirrels can't chew back in.
Seal the house, fit one-way valves at the exits, and do it only outside the pup season.
