Protect Yourself from These Common Insulation Contractor Scams

Could your attic use some additional insulation? Are you considering hiring spray foam insulation contractors in North Dakota? If so, you need to be aware of the common scams that are attempted in this industry.

Watch for the following two techniques that are common con methods used by unscrupulous insulators. If you notice any warning signs that you are being scammed, take your business elsewhere. Remember, always work with experienced, reputable insulation contractors in North Dakota.


The first of the most common attic insulation scams is referred to as shorting. As indicated by the name, this is a company’s practice of installing less material than what your attic needs for adequate insulation. Yet, they claim that they installed enough. Therefore, they are “shorting” you and your property of the promised protection.

The amount of insulation should always meet the R-value required by your environment. Colder climates require higher R-values. Older homes often feature insufficient insulation with lower R-values and gaps in the insulation.

When pulling this scam, the spray foam insulation contractor in North Dakota will inform you of the need to improve your insulation, let you know what R-value is recommended, then install the insulation. However, they only install enough to make it look like they did their job, while charging you for the full amount of insulation it should have taken to adequately insulate your attic. Their scam leaves your attic only partially insulated, still far below the recommended R-value, and leaves your bank account far below where it should be, too.


The second scam also involves installing less insulation than is needed for your space. In this case, the spray foam insulation contractor in North Dakota increases the amount of air in the insulation to effectively “fluff” the material. By doing this, they cover more attic space with less insulation material. The “completed” job looks right to the homeowner because the entire attic is covered. However, the insulation isn’t actually dense enough to do its job. It does not offer the recommended R-value, even though it may offer the recommended thickness.

To avoid this scam, make sure the spray foam insulation contractor in North Dakota can prove the R-value of the insulation. Measuring its thickness is not enough. It could be “fluffed.”


How can you avoid insulation scams? One of the best ways is to work only with trusted spray foam insulation contractors in North Dakota. Look for a company that is well-known in the industry, can provide references, is up-front with pricing and installation processes and puts everything (including a satisfaction guarantee) in writing.
