Key takeaways
- Compare scopes, not just totals.
- Ask whether air sealing is included.
- Ask how old insulation, moisture and hazards are handled.
- A good installer explains the work and welcomes your questions.
Compare the scope
A clear proposal lists each area, the material, the depth or R-value, whether air sealing is included and what is done with the old insulation. Two proposals with very different totals often have very different scopes.
Ask for the details in writing.
Ask about the prep
Good insulation work starts with preparation: sealing leaks, installing baffles, protecting recessed lights and flues, and checking for moisture. Ask how the crew handles these and how they protect your home and your attic storage.
A contractor who skips the prep is skipping where the performance comes from.
Ask about the unknowns
Attics and crawl spaces hide surprises: moisture, pests, old vermiculite, damaged wiring and poor ventilation. Ask how the contractor handles each of them and how they will tell you before extra work is added.
Honest answers beforehand make the job easier.
Watch how they communicate
A good installer explains what they found, shows you photos, tells you what they recommend and leaves the work area clean. They answer questions plainly and do not rush your decision.
Pay attention to this from the first phone call.
Quick answers
Should I get several proposals?
Comparing two or three is reasonable, as long as you compare the same scope.
What should be in writing?
The areas, material, depth or R-value, air sealing, removal and cleanup.
When is a good time to insulate?
Any time. Attics and crawl spaces can be done year-round, and early fall and spring are popular.
