"Matt was very good about keeping all appointments and very friendly. His work on the insulation was nice and neat and very effective. Good adhesion in all surfaces, and he even made a special trip back on our small job to finish insulating several windows. Matt gave the best service and best product of all the contractors I’ve had to hire in the last year. We may ask him to come back and insulate the rest of the garage!"

"Moshe and his team at Attic Kings are amazing! When I contacted them, they got back to me almost immediately with a date and time for an estimate to install insulation. Moshe was very communicative, texting and calling to let me know when he would arrive. On installation day, Moshe made sure to keep everything as clean as possible, and everything went incredibly well. They are all so kind--would definitely hire again!"

"I was referred to this company from a friend that used them in the past. I needed to remove part of drywall and replace the insulation inside due to a leak from one of the pipes. At first I called the office and told them what the problem was. The office sent Juan to my house to check and see the job. Juan came over the following day and looked the problem. He was able to give me a quote on the spot. 
The price seem to be fair so I hired them for that job. Juan than scheduled me for 2 days later and he told me that it will take 1 day to complete and another day to paint. 
I was happy with the fact that he came over when he said he will and he did complete the job the same day. The paint work was completed the following day and I?m happy with the results.

Drywall Insulation FAQs, answered by experts

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.

Textured walls can increase the value of your home if the style is modern and seen as a desirable feature and not something a prospective buyer would need to remedy. A good example of this is popcorn texture versus Venetian plaster. The plaster wall would add value to your home, whereas the popcorn texture may be something a new buyer would want to remove.

The best tool for skim coating drywall is a skim coating blade, which can smooth out joint compound in wide stretches. While you could use a smaller drywall knife for skim coating, the smaller size means it’ll take longer to smooth out each section. Instead, consider investing in a skim coating blade for the quickest application.

Wet-sanding and dry-sanding each have pros and cons. Dry-sanding is less messy, so it’s a good option if you’re trying to minimize dust (for example, if you’re sanding an occupied home or working with particularly dry or dusty drywall mud). However, dry-sanding is quicker because you don’t have to keep rinsing a sponge or wait for it to dry before painting.

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.
