Ask before you sign

Hiring a spray foam contractor is a significant investment, and the difference between a good install and a bad one shows up in your energy bills and your comfort for years. A professional who understands building science will answer these questions confidently; a guesser will hesitate. These are the questions that separate the two.

Credentials and verification

• Are you actively licensed in Colorado, and can you show proof?
• What is your insurance coverage, and does it include workers compensation?
• Can you provide local references from projects like mine — attic, basement, or outbuilding?

Technical project details

• Which foam do you recommend for this specific area — open-cell or closed-cell — and why?
• What exact R-value will this installation achieve?
• How will this address my specific problem, such as stopping ice dams or cold air infiltration?
• If insulating a basement or pole barn, will this create a proper vapor or moisture barrier?
• What is your ventilation and containment plan during application?

Estimates and logistics

• What is the total estimated cost, and what does it include?
• Can you meet my desired timeline, and how long is the cure before I can use the space?
• Is there any obligation if I receive a quote and decide not to move forward?
