"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 hired Attic master to come over and check the attic for some bad smell. Adam came over to my house and went up to the attic and checked the problem there... He recommended me to remove the old insulation and to place a new one. His price and warranty were good... so i hired them. The following morning, he came over with his worker and took out all the old insulation while his worker placing the new one. The work was completed the same day and the problem of the bed smell has been solved."

"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

It doesn’t matter which way you lay drywall, and you can choose to install it horizontally or vertically depending on the size of the wall and how tall the ceiling is. It’s easier to lay drywall sheets vertically if you have a taller ceiling, but laying sheets horizontally makes it easier to apply joint compound.

You can put certain types of plaster over other types, but doing so isn't always the best idea. For example, putting a coat of gypsum over lime plaster is possible, but doing so will limit the lime plaster's breathability and potentially affect its performance.

Since cement plaster tends to leave a textured surface, no matter how much you smooth it, some people prefer to use gypsum plaster as a topcoat over cement plaster, creating a smoother surface.

Yes, any parts of drywall that are wet or overly moist will need to be replaced. Drywall is intended to be dry (it’s in the name, after all.), as excess moisture can lead to mold and mildew and eventually corrode your home’s foundational building pieces. Do regular inspections in your home to make sure all your plumbing is intact and in good condition—this will go a long way toward preventing leaks.

A nail in drywall cannot hold very much—usually only a few pounds. A nail in a stud can add support and hold around 20 pounds. If you are trying to hang something heavier, get some help from drywall anchors—toggle bolts are very strong and able to withstand more weight.

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.
