"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."

"The fellows did a great job with this house.  The work is really quite excellent, and they kept us informed with how long it would take, how it was going, and could speak in understandable sentences.  They were polite and they worked very quickly.  
We were amazed and how quickly they did this job, as it was perfect and not at all sloppy, which you easily see in others who are quick and sloppy.  They were anything but.   They cut around several outlets and exterior items on the house and that was done well.  I would definitely recommend to anyone.  We also cannot believe how much WARMER THE BACK OF THE HOUSE is now - especially as it faces NORTH and was quite cold for the last 15 years.  We hope to be able to have them do the rest of the house as we like the insulation put in and the type and quality of siding that was used.  We would recommend most definitely."

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

Drywall Insulation questions, answered by experts

Through expert matching of texture and paint for an invisible repair.

Textured walls are a great way to hide imperfections left over by drywall installation, but many homeowners feel like it’s an outdated look, despite there being so many types of drywall texture. And while the textured walls of today are a far cry from the popcorn ceilings and faux stucco of our grandmother’s homes, if you want a more modern look or you want to install wallpaper, it’s time to smooth out your walls.

Plaster is a pretty tough surface, but it can still sustain damage from things like bumping against it, water issues, dampness, extreme humidity changes, and plain old age. Most plaster walls last hundreds of years and will only be taken down to the base layer when major repairs are required. Being cautious around the wall, not placing furniture against it, and ensuring stable humidity are all great ways to reduce possible damage.

You can paint over drywall mud about 24 hours after application, but the exact timing depends on factors like humidity, temperature, and the thickness of the mud. For the best results, ensure the mud is completely dry to the touch and has changed from a darker gray to a lighter, chalky white. Don’t forget to sand and prime the drywall surface before you paint to create a smooth, even finish.

There are a few ways to figure out if your walls are plaster or drywall, but the pushpin method is probably the easiest option. To try it, choose a part of your wall where you can insert a pushpin or thumbtack without leaving an obvious mark. If it goes in easily, you have drywall. But if the wall is tough to penetrate, that’s plaster.
