How to Choose a Spray Foam Contractor (US Checklist)

The contractor matters as much as the foam. Use this checklist to pick a reliable US pro.

Before you hire

• Confirm licensing, insurance, and manufacturer certification
• Look for SPFA (Spray Polyurethane Foam Alliance) affiliation
• Get at least three itemized quotes
• Read recent reviews and ask for local references
• Get warranties and guarantees in writing

Red flags

• Vague quotes with no foam type or thickness listed
• Pressure to sign on the spot
• No proof of license or insurance
• Prices far below the rest (often means thin application)

Questions to ask

What foam type and thickness? How do you handle ventilation and re-occupancy? What warranty do you provide? Will I get documentation for tax credits and resale? Good contractors answer all of these clearly.
