"We recently had blown in insulation installed in our home and couldn’t be happier with the experience from start to finish. The team was kind, professional and incredibly prompt. They showed up on time explained the process clearly and treated our home with respect. What really stood out was the pricing after receiving a much higher quote from another company their estimate was very fair and transparent with no pressure or upselling. It was clear they care about doing honest work at a reasonable price. The installation was completed efficiently, and the whole process was smooth and stress-free. I would definitely recommend them to anyone looking for insulation work great service, great value and great people."

"nick and his crew were experienced and very knowledgeable in their product and the job they are hired for. I like the quick communication and the being on time when it came to perform the job. I would highly recommend hiring NM Enterprises for any job that has to do with insulation. Very professional and they take pride in doing a great job for their customers. Also, did items beyond what they were hired to do like, rerouted my kitchen vent that the builder or roofers did not vent through the roof, also removed some items that were left in attic from another owner. Again, i recommend hiring NM Enterprises for your next insulation job."

"I recently used the spray foam from Spray Genie South Ben, and I couldnâ t be more satisfied with the results. The application was smooth, and the foam expanded perfectly, providing excellent insulation and coverage. I highly recommend their spray foam to anyone looking for reliable, high-quality insulation products. The product performs exactly as advertised, and the results speak for themselves!"

"David and team did a fantastic job. I had 30 year old attic insulated. Old insulation removed and reblown in. David sealed around ceiling lighting, gaps where mice had gained entrance, sealed around windows. They were reliable, efficient, personable, cost effective, and most of all listened to our problems for resolution. We were pleased that we hired DAP and Sons."

Insulation FAQs, answered by experts

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.

Yes, PEX pipes should be insulated in certain situations. While insulation is not always necessary for pipes running through insulated interior or external walls, it is recommended for any pipes located in uninsulated rooms, unheated areas, or outside, especially in regions with cold winters. The primary reason is to prevent freezing. Although PEX is more resistant to cracking from freezing than other materials, repeated freezing and thawing can weaken the pipes over time, increasing the risk of a burst.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.
