"Standard Insulating Company sent David E to our house to a**** a problem we were having with hot spots in certain areas. David was up front with his assessment and explained everything in a way we were able to understand. The quote he emailed us was surprisingly reasonable with no hidden fees or surprises. We chose to have our insulation capped as well as radiant barrier installed. The work was scheduled less than a week later and the crew was professional, knowledgable, quick, efficient and kept the whole work area clean. I highly recommend Standard Insulating Company to anyone looking to have any type of insulation work done."

"Behr was fantastic! Nick and Dakota were extremely professional and provided a fair quote. They removed the old insulation, installed new insulation in my attic, and sealed all the gaps to help improve my heating efficiency. I have nothing but positive things to say about their work."

Drywall Insulation FAQs, 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.

Only use spackle on plaster walls when the imperfection is small. It’s best used for nail holes or small dings in the plaster. Spackle dries quickly, allowing you to continue the repair process shortly after using it. Plaster can be tricky to repair, though, so if you run into issues, call a pro so that you don’t risk further damage.

Options include bricks, natural stone, and concrete blocks. Choose based on durability, aesthetics, and budget.

Many homeowners choose to install tongue and groove over drywall. The great thing about this type of ceiling is that it hides imperfections. If your drywall is a little bit wonky or has some minor damage, the tongue and groove planks should cover it and give it an even appearance. Installation is simplest if you install battens over the existing framing before installing your tongue and groove planks.

You should start looking for a drywall installer by choosing a local company with positive online reviews and ratings with the Better Business Bureau (BBB). Next, confirm that the professional is properly licensed using Angi’s contractor licensing tool, and ask the installer if they are fully insured. It’s a good idea to ask for recent customer references and call them to get their honest opinion about the contractor and their work. You can also ask the installer if they guarantee their work or provide a workmanship warranty.
