"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"I would just like to thank this company for the work they did in my home! Iâ m very late writing my review but I wanted to see how different my home felt since having this service. Complete Home Solutions serviced my house on November 20, 2020, The crew consisted of Brad, Jason, Aaron and John B. There was another individual who did my drywall work, but I didnâ t get his name. There are no words to describe how much I appreciate your professionalism, knowledge, experience, cleanliness, kindness...etc. You guys did such a wonderful job! Since getting insulation put in my sonâ s room, I can feel the difference, a huge difference!! Also, I would like to thank Noah for the first initial visit and explaining to me in detail about the difference in the products. If youâ re looking for a company to provide service to your home, thereâ s no need to look any further! Iâ m looking forward to hiring them again, for my crawl space."

"Our first interaction with Atlas was with Shannon. As knowledgeable and personable as one could hope for. She clearly explained cost effective measures to better insulate our house. We opted for sealing and insulating our attic and weather stripping a number of doors. We were very pleased with the workmanship and the energy savings they produced. They also helped us get a PEPCO credit which reduced the overall cost of the job. A winner!"

"I needed a company that would blow insulation into the walls of my basement. Terra Insulation did the job for me. The technicians were expert at drilling the holes, adding the insulation and clean up. They were professional and informed me of when they were taking a break, etc. They even replaced the disks and added drywall paste to ready the walls for my painter. I highly recommend this company for its dependability and expert installation."

"We had Xanvria remove the old insulation in our attic, air seal the attic, and install new R-49 batts. They did a really good job, were professional, and explained what they were doing along the way. Everything came out clean and we?re very happy with the work. I would definitely recommend them."

Drywall Insulation FAQs, answered by experts

If you suspect black mold is inside your walls, do not punch a hole in the drywall yourself to look. Call a mold inspection expert to help you. Some signs of a potential black mold infestation inside the wall include an unexplained musty, damp smell. Some people liken it to rotting vegetables. You may smell it most strongly through a wall outlet. If you and your family are experiencing constant coughing or symptoms that feel like an unexplained allergy, it could indicate black mold behind a wall.

If you don’t have studs in the area where you want to install your TV mount, you may still be able to install a TV mount on drywall. The easiest way to install a mount on drywall is by using drywall anchors—but not just any plastic anchors. Choose molly bolts or toggle anchors, which have a weight capacity of around 50 pounds. For added support, consider pairing drywall anchors with a wall mounting plate. Extra heavy TVs may need to be mounted via the ceiling joists or beams.

The cost to install drywall is between $1.50 and $3 per square foot, while shiplap installation costs between $2 and $7 on average. In most applications, shiplap installations cost more than that of putting in drywall. However, several ways exist to reduce shiplap prices, especially for small locations or accent walls, which can keep the total cost of shiplap competitive with that of drywall.

Which style of corner bead you choose—whether metal or paper-faced—depends on your preference and if you’re comfortable using metal-cutting tools and a hammer. Metal bead offers superior strength and durability but its installation is slightly more involved. We’d say for most cases, it’s better to use metal bead but if you’re not comfortable working with metal, paper-faced bead will work just fine. 

Technically speaking, you can use drywall primer over plasters. However, oil-based primers work the most effectively on wall plasters. Meanwhile, water-based primers work just as well with drywalls. Nowadays, there are also universal primers suitable for drywall and plaster. Overall, you will be fine as long as you are using a trustworthy brand.
