The Insulation Process – What You Should Expect from 5C Energy Inc.

Basements and crawl spaces let too much air pass through. That’s why the 5C Energy Inc. insulation techs create a barrier that minimizes heat transfer and blocks moisture. Quality insulation improves indoor temperature and reduces the risk of mold infestations.


Before the 5C Energy Inc. insulation techs begin, we clean and dry the area and remove any debris that could get in the way.  

Insulation Application

Next, we apply the high-tech spray foam insulation. This type of insulation comes in two forms — open-cell and closed-cell. 

Open-cell is lighter and cheaper but offers less resistance to moisture, while closed-cell is denser and provides the best R-value and water resistance. 

After the foam is sprayed, it expands to fill gaps and cracks.


The spray foam insulation to cure and harden. Our insulation techs will make sure there is plenty of ventilation and will set up fans if needed. Remember, the curing time can vary due to many factors like weather and the type of insulation we used.

Inspection for Quality

5C Energy Inc. inspects everything we do — more than once! We check to make sure the seal is complete. The surface should be firm and even, with no soft spots or cracks. 

Finishing Touches 

Depending on local building codes and your preferences, we might apply a fire-retardant paint or barrier over the foam insulation for added safety. Our insulation techs will let you know if fire-retardant is required in your area based on your local building codes. 

We never recommend trying to DIY crawl space insulation in Worcester, MA. It really is something that should be left to the people who are experienced in it.
