5 Factors to Consider When Choosing a Spray Foam Contractor

Spray foam insulation is becoming increasingly popular among homeowners and businesses for its energy efficiency and cost-saving benefits. However, for those considering this type of insulation, it is important to choose a reputable and experienced contractor to ensure a quality installation. Here are five factors to consider when choosing a spray foam contractor.

1. Experience and Qualifications

One of the most important factors to consider is the experience and qualifications of the contractor. It is important to choose a contractor who has experience with spray foam insulation and can demonstrate a track record of successful installations. Additionally, it is important to ensure that the contractor is properly licensed and insured in accordance with local regulations.

Ask the contractor for references and check them thoroughly. Look for reviews and ratings on websites such as Angie’s List or the Better Business Bureau. Also, ask if the contractor is a member of any professional organizations, such as the Spray Polyurethane Foam Alliance (SPFA), which provides training and certification programs for spray foam contractors.

2. Product Knowledge

It is important to choose a contractor who is knowledgeable about the products they use. There are different types of spray foam insulation available, each with its own unique properties and benefits. A knowledgeable contractor can help you choose the right type of foam for your specific needs.

Additionally, a knowledgeable contractor can explain the pros and cons of each type of foam and help you understand the differences between open-cell and closed-cell foam. They can also explain the R-value of each type of foam and help you choose the right thickness for your specific application.

3. Safety Practices

Spray foam insulation requires the use of chemicals and can be dangerous if not handled properly. It is important to choose a contractor who follows proper safety practices and uses the appropriate protective equipment.

Ask the contractor about their safety practices and the equipment they use. Make sure they use the proper ventilation and have a plan in place in case of an emergency. Additionally, ask about the safety record of the contractor and if they have had any accidents or injuries.

4. Warranty and Guarantee

A good spray foam contractor should stand behind their work and offer a warranty or guarantee. Ask the contractor about their warranty and what it covers. Additionally, ask if they offer a guarantee on their workmanship.

A good warranty should cover defects in materials and workmanship for a certain period of time, typically 10-20 years. A good guarantee should cover any issues that arise due to poor workmanship, such as gaps or cracks in the foam.

5. Price

Price is always a factor when choosing a contractor, but it should not be the only factor. While it may be tempting to choose the lowest bid, it is important to consider the quality of the work and the reputation of the contractor.

Ask for a detailed quote that includes all costs associated with the installation. This should include the cost of materials, labor, and any additional charges, such as disposal fees. Additionally, ask if there are any discounts or promotions available.


Choosing the right spray foam contractor is crucial for a successful installation. Consider these five factors when choosing a contractor to ensure a quality installation that provides energy efficiency and cost savings for years to come.
