"John and his team did amazing work removing the old, insufficient insulation in the attic of my nearly 120 year old home and replacing it with a much higher R-value blow-in insulation. The difference in the look of the attic is phenomenal, and I am confident it will be good for the energy efficiency of our home as well. The entire project took around 8 hours and the team even cleaned up to the point where you could hardly tell any work was done. I found dealing with John and Spray Foam Insulation Systems to be a very pleasant experience. Very honest and forthright, while offering a very fair rate for the work. I highly recommend working with them."

Drywall Insulation FAQs, answered by experts

A post-drywall inspection could uncover many problems that weren’t present during the pre-drywall inspection, including insufficient insulation, missing weather stripping, improperly installed plumbing and lighting fixtures, flooring damage, drywall damage, plumbing leaks, aesthetic issues, and more. Structural problems, which are often expensive to fix and are common reasons to walk away after a home inspection, are easier to see before the drywall goes up, but a post-drywall inspection may highlight minor issues with house settling and foundation problems.

You may need to replace drywall because of smoke damage. If the drywall is covered in soot, you may be able to clean it, but it will require a lot of time and effort. You could spend hours cleaning the drywall only to find there is more damage and it needs to be replaced anyway. It’s usually easier and safer to remove the smoke-damaged drywall and replace it.

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.

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.

Whether to repair or replace water-damaged plaster depends on the scale of the damage. For small, limited areas, you can often perform a repair yourself. If you choose to paint over small patches, ensure the surface is completely dry and apply a coat of antifungal primer first to prevent mold growth. However, simply painting or plastering over the damage is only a temporary solution that doesn't address the core problem. For more extensive or long-term damage, the plaster may be compromised, and there is a risk of mold. In these cases, it is recommended to remove the damaged section of plasterboard and replace it. You may consider hiring a professional for the repair, and it's worth noting that water damage is often covered by home insurance.
