Homeowners and builders often hire insulation contractors to improve the energy efficiency and comfort of homes and buildings. Their expertise in assessing, planning, selecting materials, and skillful installation makes a substantial difference in building performance.

When choosing an insulation contractor, homeowners should consider factors like customer service, experience, and warranty. Ideally, homeowners should obtain quotes from multiple contractors to compare pricing and services offered.

Top 5 Reasons to Choose Spray Foam Insulation for Your Home

The amount of time and cost of the project should be listed in the estimate, as well as any potential unforeseen issues that may impact the timeline. Additionally, the contractor should provide a written warranty that covers both the product and installation workmanship.

If a contractor does not offer a written warranty, they should be questioned about their qualifications and credibility. For example, if they advertise a specific R-value for insulation, you should ask them how that rating was determined. You can also find out if they have any specialized training in the field of insulation. If they are unable to provide an adequate answer, you may want to choose another contractor.

In addition to a warranty, you should make sure the contractor has workers’ compensation and liability insurance. This protects you if the contractor’s crew is injured on your property while performing work. It is also important to verify that they have the appropriate licensing for your area. Spray foam insulation, for instance, requires a special license. Additionally, you should also understand how the contractor’s installers are paid. For example, if they are paid by the hour, they may rush the review and installation process to get on to their next job.
