I obtained 3 quotes for replacing the insulation (not just topping it up to R60) in our attic so I know EcoComfort is competitively priced. And after selecting them I know they do a fabulous job too. They are professional from start to finish - response times, the quote, punctuality, the actual work, cleanup, and follow up. John and Louis worked from 8-5 doing the work and they surpassed all my expectations. They gave me an opportunity to inspect the vacuumed attic and the final result after disinfecting, adding baffles and blowing in the insulation. You can't go wrong with this company.
