Question 1

How is this insulation contractor directory built?

Accepted Answer

We list insulation installers, air sealing and weatherization companies, and home energy auditors by state using public Google Business Profile information (name, phone, address, hours, and rating), and spread them across each state for coverage. Listings are tagged insulation or energy audit from their profile so you can filter. Details can change, so confirm directly before hiring. WattSimple is independent and does not endorse any listed company.

Question 2

Should I get an energy audit before insulating?

Accepted Answer

Usually, yes. A home energy audit with a blower-door test shows where air actually leaks and which assemblies are under-insulated, so you spend on the attic floor or rim joist that matters instead of a wall that doesn't. Many utilities subsidize or run audits, and the auditor's report doubles as the scope for insulation quotes. Look for BPI (Building Performance Institute) or RESNET credentials.

Question 3

What should I look for in an insulation contractor?

Accepted Answer

A quote that states the material, the R-value being added, the square footage, and whether air sealing is included and where. Air sealing before insulating is what makes attic insulation perform. For spray foam, ask about ventilation during curing and the attic's combustion appliances; for any attic job, ask how recessed lights, bath fans, and attic ventilation are handled. Confirm any general contractor license your state requires and get liability insurance in writing.
