"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

You should stagger drywall sheets to help prevent cracking. The joints between drywall sheets are the weak spots, so if you install drywall with seams aligned, you’ll create weak lines that run across the length of the wall and extend from floor to ceiling. But when you stagger drywall, the solid sections of panels will support the joints. This can prevent seams from cracking or separating due to fluctuating temperature and humidity, vibrations from movement inside the home, and gravity.

Drywall anchors won’t work on plaster. Instead, they will more than likely cause more damage and pull out the plaster. The best type of anchors to use on plaster walls are the ones that will bite into the surrounding area, such as molly bolts and toggle bolts. Masonry anchors with expanders on the sides also work for lighter pictures.

If you’re installing new drywall, you may need to skim coat the drywall first for a smooth finish and to allow the primer to adhere to the wall. It’s only necessary if there are imperfections in your drywall due to issues with the studs or improper drywall installation. If you’re refreshing existing walls, you may want to skim coat if there are imperfections across the wall. As an alternative, you can repair your drywall and sand it for a smooth finish before painting.

Plaster can be a difficult DIY to master, especially if you plan to plaster an entire room, rather than patch a small area. Before you begin a plaster DIY project, you need to know which tools and type of plaster to use. It's also important to know how to prepare the surface and apply the plaster for a smooth finish. If that all sounds like a lot of work, you may prefer hiring a local plaster repair contractor to do the job.

Yes, professionals often repair minor wall openings made for insulation injection to restore the surface.
