"Tempest insulation with Fernando are going to be my go to team for any future insulation needs. I used tempest for a R44 blown in insulation. Fernando was on time for the estimate, sent me a follow up with responses to all my questions and began the work at 8 am on the dot! He and his crew were timely, professional, clean and were in and out of my place in less than a day and cleaned up everything after themselves. I would highly recommend them!"

"They came out to look and suggested that this was not an insulation problem, but a problem with the duct work for the A/C. They had recommended one of their A/C subcontractors who did an excellent job."

"The project was to insulate the home (1800 sq. ft) --blown in R38 for the attic and 6 inch BATTS (R-19) for the basement/subfloor to protect our newly installed hardwood floors and to provide insulation in general. Every aspect of the process from initial consult call to bidding to project completion was superb. Craig provided excellent customer service. He understood our objective was to get the most value for our investment. He showed up on time and performed the project professionally and seamlessly. I highly recommend this contractor for insulation services."

Insulation questions, answered by experts

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.
