Alliance Environmental Group out of Sacramento, restored our attic after smoke damage from the Kincade fire in Windsor. Jose Roman, and Luis arrived promptly, prior to the scheduled time, and screened off their work area with plastic sheeting from floor to ceiling, so as not to contaminate the rest of the house and garage; they wore protective gear at all times. Using huge hoses they vacuumed the old insulation out and thoroughly cleaned the attic area. Jose took before, during and after photos of the complete process. A separate hose blew in new insulation. It looked much better than the original job when the house was built. They hauled away huge bags of contaminated insulation. They left the property just as spotless as when they arrived (even swept a few leaves from the sidewalk). They were professional, polite, friendly and efficient. I highly recommend this team (Jose’s team) and their services.
