When you call, ask for a whole-home assessment with a written scope that lists target R-values for New England, air-sealing details, vapor/moisture control strategy, and a clear timeline for any rooms impacted. Inquire about Mass Save rebates, blower-door testing, and post-install thermal imaging to verify results and maximize incentives. Share photos of drafty areas or ice-dam spots to get a precise quote, and confirm workmanship/product warranties, cleanup and disposal plans, and how they’ll protect your home during the job.
