"Two men showed up and they got to work after setting things in place. Will was very plesant and explained what they did. My home is 104 years old and I found out his home was older than mine so I felt he knew the importance of the insulation for my home. I had very minimal in place and he assured me it would be much better now. I appreciated the time spent and the work preformed. I would recommend this company to anyone needing insulation for their home."

"Would rate very good to excellent. . Personable, professional, punctual. Carpet, furniture, doors, windows and trim well protected before any work was started. Perhaps could have had less drywall damage with wallpaper removal in half of room. Wall surface repaired, primed, prepped for painting including sanding and painted.. ."

"There's no better expert in insulation than someone who has lived in Alaska and did it up there where it's -40. I know it doesn't get that cold here in NWA but if he can insulate homes up there?! Yeah, just talk to Charles for half a second and you'll see he knows more about your insulation needs than anyone else. He sprays perfectly even so there isn't waves, it's all even so the temp stays perfect. He's got all the pictures to show you. If you want some amature insulation don't go here, if you want the absolute best? This is it."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Drywall Insulation FAQs, answered by experts

You’ll want to inspect your plaster walls for signs of damage before painting. If you notice soft spots, deep cracks, bubbling, or areas where the plaster is crumbling or pulling away from the wall, it likely needs repair. While small hairline cracks are common and likely cosmetic, you should address larger issues before painting to ensure a quality, smooth finish.

Yes, you can hammer a nail into a wall stud. But before you do, it’s important to confirm that you’re actually nailing into a stud—and not wiring, pipes, or ductwork. To check, find a few more studs in the wall, then measure to make sure they’re either 16 or 24 inches apart.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

There are six levels of drywall finish, from 0 to 5, that refer to the amount of work performed during the finishing process.

Level 0: Drywall is hung with no finishing work.

Level 1: Tape is placed over the seams between drywall sheets.

Level 2: A thin layer of mud is applied over the tape and screw holes. This level is common for utility rooms or walls that will be covered.

Level 3: A full coat of mud covers the screw holes and tape, but the surface is not sanded. This is often used in garages.

Level 4: This is the most common finish for visible interior walls. It involves applying two coats of mud over seams and screw holes, with sanding between each coat, creating a smooth surface ready for flat paint.

Level 5: This is a high-end finish for luxury homes. It includes full taping, mudding, and sanding, plus a final skim coat over the entire surface before painting.

Ceiling-mounted curtains won’t damage the ceiling if they’re installed properly. Using the right anchors or securing the brackets into joists will ensure the curtain weight is properly supported and prevent damage. However, overtightening screws, using weak anchors, or repeatedly removing and reinstalling hardware in the same spot can cause cracking or sagging over time. In that case, you might have to call a pro for ceiling repair.
