Spray foam is priced by the board foot: one square foot, one inch thick. That makes the cheapest bid easy to spot. It's almost always thinner foam, the wrong foam for the spot, or a quote that leaves out the ignition or thermal barrier your space needs.
We're not the cheapest, and we're not trying to be. Your written quote lists every area, the foam type, the thickness and the R-value, and we check depth as we spray. The number we quote is the number you pay.

Most bad spray foam jobs go wrong for the same few reasons. Here’s what to check before you hand anyone a deposit:
More insulation on top of leaks doesn't stop drafts. A good installer seals the attic floor, rim joists and foundation before insulating.
A quote should list the material and the thickness or depth for each area. A low price with no thickness listed usually means thin insulation.
Efficiency Maine rebates can cover a real share of insulation and air sealing. Ask whether the installer will help you with the paperwork.
Foam in basements, attics and living areas may need a protective covering, depending on how the space is used. A pro knows the requirements.
Insulation isn't a fix for a leaking roof or a flooding basement. A good installer checks for water and tells you if something needs repair first.
