"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."

"This company cares. They put people above profit. I was in a bad situation, after a nasty winter my roof seemed to be disintegrating before my eyes. It went really fast. Then Daryl stepped up to help me out of a difficult situation. Within hours they expedited the crew, and Walter and Lauren ordered materials and made my roof a priority. Now with three days of rain coming I know my house is protected and it looks gorgeous."

"George came out promptly and did a thorough inspection of the crawlspace and provided options on what can be done. The insulation work was performed by Jesus who also found and fixed two foundation cracks. Encapsulation was done by Juan's team and they all did a great job. They were able to perform all the work with a very narrow opening into the crawlspace and were also able to fit in the dehumidifier. After installation there was a minor issue with the dehumidifier and Craig came right away to fix it. Great experience and I'd definitely use their services in the future if need be."

"I actually did not pay them. I had a free inspection and they showed me that it was not an insulation problem. I didn't have to pay for anything. They were all very professional, and the inspector got in my attic and checked my soffits and insulation type and thickness. All was up to code. He said it could be a hvac issue, so thats my next approach. Thanks USA Insulation. ...."

Drywall Insulation questions, answered by experts

The tool you use to sand plaster will depend on the size of the project. If you’re just working on a small section of your wall to get rid of an uneven spot on the surface, hand-sanding might work. However, for larger projects, a drywall sander can make a huge difference when it comes to both time and elbow grease—and an orbital sander can help for detailed areas such as around ceiling fans.

While certain types of textured walls can seem dated (looking at you, popcorn), textured walls are a common sight in both older and more modern homes. The main reason textured walls may be here to stay is that they are an excellent way to hide minor imperfections on a wall and give it a finished appearance. Some homeowners think a coat of paint on drywall is a bit industrial-looking. However, that look works perfectly in modern home design

Yes, you can mount a TV on plaster walls—as long as you attach it to the studs. Alternatively, you can use toggle bolts, molly bolts, or another type of hardware that’s strong enough to support a TV. 

If you aren’t comfortable with this type of project, you can hire a pro. The cost of mounting a TV to a plaster wall ranges from $25 to $600 (or more), depending on the TV’s weight, size, and other factors.

Yes, wainscoting is installed directly over drywall. However, ensure the drywall is in good shape since it will support the wainscoting. If the drywall has issues, such as holes, mold, or mildew, repair them before installing the wainscoting. Alternatively, you can install a plywood substrate before attaching the trim.

Most repairs take 1-3 days, depending on drying times for joint compound and paint touch-ups.
