12 Questions to Ask Before Hiring a Spray Foam Contractor in Arkansas
The best way to avoid a bad spray foam job is to make every contractor answer the same 12 questions in writing before you compare prices. Spray foam is a two-chemical product mixed and applied on site, so the installer’s training, equipment, and paperwork decide the result more than the brand on the drum. Use the questions below with every quote you collect, including ours.
Most horror stories homeowners post online trace back to a handful of skipped questions: no proof of insurance, no thickness on the quote, no fire barrier, no plan for moisture or re-entry. We’ve grouped the 12 questions by what they protect you from, and added what a good answer looks like. Last updated October 2026.
Quick answer: the 12 questions at a glance
Ask every contractor about (1) license and insurance, (2) installer training, (3) local references, (4) the exact foam product and data sheet, (5) blowing agent, (6) thickness and R-value per area, (7) fire barriers, (8) pre-spray inspection, (9) ventilation and re-entry, (10) HVAC and humidity changes, (11) warranty terms, and (12) what happens if something goes wrong. Details for each follow.
Credentials and protection
- Are you licensed and insured for this work? Ask for a certificate of general liability insurance and proof of workers’ compensation coverage, and have the insurer’s name on paper. Contractor licensing in Arkansas is handled by the Arkansas Contractors Licensing Board, and requirements depend on the type and dollar value of the job, so confirm what applies to your project directly with the Board. Workers’ comp rules for construction employers are also strict in Arkansas, so an uninsured crew injured on your property can quickly become your problem.
- What training do your installers have? The Spray Polyurethane Foam Alliance runs a Professional Certification Program (PCP) built to ISO 17024 standards, and foam manufacturers offer their own product training. A good answer names both and tells you who will physically be on the rig, since the person who quoted the job is not always the person who sprays it.
- Can you give me local references and photos of similar jobs? A crawl space is not a roof deck. Ask for Arkansas jobs like yours, ideally from homeowners you can call, and ask to see finished photos of attics or crawl spaces that match your project.
The product and the spec
- Which foam, from which manufacturer, and can I see the data sheet? You should get the product name, whether it’s open-cell or closed-cell, and its R-value per inch. Beware anyone claiming wildly high per-inch numbers; see our pages on open-cell and closed-cell foam for realistic figures.
- What blowing agent does the closed-cell foam use? Older closed-cell formulas used HFC blowing agents with a high global warming potential. Ask the contractor to confirm they are not spraying old HFC stock. See GWP-1 foam explained.
- What thickness and R-value will each area get, in writing? The quote should say, for example, “attic roof deck, 6 in open-cell, R-22,” not just “spray foam attic.” Then compare against the Arkansas energy code for your climate zone, because minimums differ by assembly (attic, wall, floor over crawl space).
- How will you handle fire barriers? Under the International Residential Code, spray foam generally needs a thermal barrier (such as 1/2-inch gypsum board or a listed intumescent coating) in occupied spaces, and an ignition barrier in areas like attics and crawl spaces with limited access. Ask which one applies to your job, whether it’s included in the price, and whether your local building department has its own requirements. See is spray foam flammable.
The building and the plan
- What will you check before you spray? A good answer covers roof leaks, existing moisture, pest activity, shingle brand and warranty, and combustion appliances. Foam can hide problems rather than fix them. See hidden roof leaks, shingle warranty, and pests.
- What’s the ventilation and re-entry plan? The EPA advises that occupants vacate during application and not return until the foam has cured, the building is ventilated, and it has been cleaned. Some manufacturers recommend about 24 hours for professional two-component systems, but timing varies by product. You should get a written re-entry time from your contractor, based on the manufacturer’s guidance. Extra care is warranted for children and anyone with asthma. See how to prepare for installation.
- Does my HVAC or humidity control need to change? A sealed attic or crawl space changes how the house breathes, and Arkansas humidity makes this matter. Ask how the contractor handles combustion air, ductwork in the new conditioned space, and moisture control. See attic humidity.
Accountability
- What does your warranty cover, and for how long? Get it in writing, including whether it covers workmanship, off-ratio or poorly mixed foam, and removal. Ask separately about the manufacturer’s product warranty and the contractor’s workmanship warranty, since they are not the same thing.
- What happens if something is wrong after the job? Ask who comes out, how fast, and who pays. If foam ever has to be removed, read about removal and its costs before you sign, because it’s far cheaper to choose well the first time.

Red flags when hiring a spray foam contractor
- A price far below every other quote with no thickness listed. Our cost guide covers how to spot a lowball.
- High-pressure “today only” discounts.
- Claims that foam is “completely safe from day one” or that ventilation doesn’t matter.
- Refusing to put foam type, thickness, or warranty terms on paper.
- No certificate of insurance, or an answer of “we’ll get it to you after the deposit.”
- Vague answers on roof deck jobs about shingle brands, moisture, or building code.

Frequently asked questions
How do I choose a spray foam contractor?
Compare at least three written quotes, verify insurance, ask about installer training, and require foam type, thickness, fire-barrier details, and warranty terms in writing. Check references from similar jobs in Arkansas.
What certifications should a spray foam installer have?
Ask about the Spray Polyurethane Foam Alliance’s Professional Certification Program (PCP) and manufacturer training, and who will actually operate the equipment on your job.
How can I tell if a spray foam quote is too low?
If it’s well below competitors and doesn’t list foam type, thickness, or R-value, the installer may be applying less foam than you need or skipping fire barriers.
Does a spray foam contractor in Arkansas need a license?
Contractor licensing in Arkansas is regulated by the Arkansas Contractors Licensing Board and depends on the type and dollar value of the work. Confirm the requirements for your project with the Board and ask the contractor for proof of license and insurance.
How long should I stay out of the house after spray foam is installed?
The EPA says occupants should vacate during application and return only after the foam has cured, the home is ventilated, and it has been cleaned. Some manufacturers suggest about 24 hours for professional two-component foam, so ask your contractor for the written re-entry time for their product.
Is spray foam insulation required to have a fire barrier?
Generally yes. The International Residential Code calls for a thermal barrier in occupied spaces and an ignition barrier in areas such as attics and crawl spaces. Ask your contractor which applies and whether it is included in the quote.
