"They came out for the estimate, were on time. Looked at my attic, let me know there were no problems with my ducting before blowing in insulation. When they came for blowing in the insulation, they came on time and cleaned up afterwords. Great Job. Would recommend them."

"They scheduled us for a Saturday because they were booked all week and they didn’t want to make us wait for an opening. They were punctual, reasonable prices, polite, and cleaned up when they were finished. I definitely recommend them."

"Hard-working young man. Arrived as agreed and worked until we had gone through all of the contents of my garage. Came with a U-Haul trailer and took off anything I didn’t want. If you need someone to help you with the heavy lifting and motivation to clean out a room or garage, Jimmy is a great choice."

Drywall Insulation FAQs, answered by experts

Plaster is denser, harder, and more porous than drywall, so it absorbs moisture differently. This means you’ll often need more prep work, such as thorough sanding, patching, and priming with a high-quality bonding primer. Additionally, you may need more coats of paint to achieve even coverage. While the process takes more time, it helps ensure a durable and professional-looking result.

Regular dusting, occasional repainting, and avoiding harsh scrubbing preserve the finish.

You should leave a gap between drywall sheets because they naturally expand and contract along with the building framing as temperature and humidity change. Most pro drywall installers leave a gap of about ⅛ inch between drywall sheets, allowing the sheets to expand, contract, and shift without cracking or becoming damaged. If you don’t leave enough gaps between slabs, the edges will press against each other when they expand, and the pressure can cause visible cracks.

There are several things you should not do when installing drywall. Common mistakes include: adding too many screws, over-sanding, not adding backing support, and installing drywall unevenly. You also should avoid screwing into the same place twice, installing Sheetrock with tapered edges on the outside, and making too many joints.

You can usually tell if you have plaster or drywall by touch (plaster is harder, colder, and smoother than drywall) or by tapping on it (drywall sounds hollow, plaster does not). If you still cannot tell, peek under an outlet cover and check the cut edges. The rough edges show the composition of the wall. You will see either drywall (two paper sheets sandwiching gypsum material) or only plaster material (no paper sheets).
