"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 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!"

"Had USA out to discuss insulating attic and exterior walls.  The concluded that doing exterior walls was not needed.
 Recommended putting several inches in the attic.  There was almost nothing up there.  The product used has a good recommendation.  compared it to several other products.  
Very clean and efficient.  Arrived almost an hour before schedule.  Called an hour before arriving to say they were on the way.  Laid tarps to protect carpet.  Finished in about 3/4 the time I expected.  Cleaned up everything.
Great experience.

"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."

"Greg, the owner, came out on two occasions to discuss the crawl space and drain tile. He is extremely knowledgeable and experienced in the crawl space industry. We had a few options and he told me about the new spray product he was using. It is this unique seamless liner that is sprayed on after preparing and insulating the area.
His crew was very professional and easy to talk to. We had some scheduling conflicts that were easy to work around and get the job done when we needed it to be finished.
The difference we noticed in the smell in our basement, the effect the insulation and seamless lining had on the air conditioning in our family room (which is above the crawl space) was immediate. We feel cooler air coming through the duct work since it isn't losing energy traveling through a non insulated space anymore and they basement smells and feels normal since the dirt and concrete is now completely covered by the new liner.
That new product is great.
Greg's company also did drain tile work in our basement. It was a different crew than the group who did the crawl space, but they were equally as professional and easy to work with. Rather than break up the job into 3-4 days they stayed late the first day to get everything ready and prepared so they could complete the job quicker. The job was done the next day. The price was very fair and the crew was extremely clean throughout thew whole process.
We now have a water tight, well insulated basement and we couldn't be happier with the results.
I have told several friends about the experience and would recommend them anytime. From Greg down to each of his crew members they really know how to do a good job and work with the customer."

Insulation questions, answered by experts

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

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.
