Insulation Questions and Answers

What does an insulation contractor do?

An insulation contractor evaluates where a home is losing heat or cooling, seals air leaks, and installs or replaces insulation in attics, walls, floors and crawl spaces.

When should I add or replace insulation?

Consider it when rooms are drafty or hard to keep comfortable, energy bills climb, attic insulation looks thin or compressed, or insulation has been damaged by leaks or pests. Fiberglass, cellulose and spray foam suit different areas, so ask the contractor which material and R-value fit your climate and why.

How do I choose an insulation contractor?

Ask whether the contractor will assess air leaks as well as insulation levels, what material and R-value they recommend, and how they handle ventilation. Some utilities offer rebates that require specific contractors or documentation.

What affects the cost of insulation?

Cost depends on the area insulated, material type, target R-value, accessibility, air sealing, removal of old insulation and any repairs needed first.

How should I prepare for insulation work?

Clear stored items from the attic or crawl space and the path to it. Point out any roof leaks, pest issues or old wiring you know about, since those should be addressed before insulation is installed.
