"FoamCo recently insulated our basement walls. Before, we couldn’t use the basement in the winter time. We noticed an immediate difference once the insulation went in, and now our basement is our favorite cozy hangout spot in the house. They were great at explaining exactly what kind of insulation I needed and were actually the best priced bid we got."

"Had contacted another company to plow in the insulation in early December 2021 and for 3 months got the run-around from them. I contacted Ozark's Mountain Insulation and they immediately contacted me, gave me a bid and I accepted. Work done today."

"I took a while to get back to Chris and she stuck with me which I appreciate! She sent out the same rep to do the job that had come and quoted the work and he was very knowledgeable! We have noticed a big difference in the feeling of the house. Even though our house is brick they were able to provide some sort of comfort which multiple other companies refused to provide any help with. Some wouldn’t even come look."

"He was very knowledgeable and professional. After the audit we received an estimate to correct any areas that were discovered. Unlike what we originally thought our issues were not the windows and doors. The estimate was for $4000 to add insulation to the attic, increase airflow in the attic, install foam insulation around our fireplace and throughout the basement as well as removing the attic fan and adding drywall. 
The price is the estimated price for projects to be completed.

Drywall Insulation questions, answered by experts

Wet-sanding and dry-sanding each have pros and cons. Dry-sanding is less messy, so it’s a good option if you’re trying to minimize dust (for example, if you’re sanding an occupied home or working with particularly dry or dusty drywall mud). However, dry-sanding is quicker because you don’t have to keep rinsing a sponge or wait for it to dry before painting.

Drywall texture refers to the techniques used on the surface of drywall to create a pleasing visual or tactile effect. Depending on your desired outcome, drywall texture can range from incredibly subtle to a focal point of a room. Textures play a significant role in interior design and are an excellent and relatively cost-effective way to change the feeling of a room.

You can plaster over regular drywall, but it's essential to prepare the surface properly. Before plastering, the drywall should be clean, free of dust, and any loose or peeling paint should be removed. Applying a primer specifically designed for plastering can improve adhesion. Some professionals recommend applying a base coat of plaster or joint compound to create a better surface for the plaster to adhere to. Proper preparation ensures a smooth and durable plaster finish over regular drywall.

If your home was built before the 1940s and was not remodeled in the past 50 or so years, you probably have plaster walls. Aside from assuming, there are some practical ways to tell if you have plaster walls, including the following: If you knock on the wall and it feels solid, not hollow, if you can’t insert a thumbtack easily, if there are cracks that look like spiderwebs, or if your home has curved, arched, or swirled walls, doorways, or window openings.

If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.

While it’s most common to sand plaster dry, it is possible to wet-sand plaster, too. Doing so can reduce the amount of plaster dust released into the air and make it easier to work in smaller, more delicate areas (such as around wall trim). However, some people find that wet sanding leads to more imperfections, which is why larger walls are more often dry sanded to ensure an even finish.
