They installed blown-in insulation into my 100 year old home with clapboard siding. Removed and put back the siding with no problems. Used small stainless steel nails to finish the job. Team was polite and respectful as they were working. I would hire them again to insulate my attic.
Had them insulate my cape with blow in cellulose insulation and they were able to get into tight spaces without any complaints. Extremely professional, friendly, knowledgeable and a delight to work with. Would use them again.
