They were very respectful of my space, explained everything they were doing and answered all of my questions. They are a hard working customer oriented team. I would not hesitated to recommend this company to anyone."

"Contacted Master Attic via Angi and Alex, the technician came to evaluate our attic and crawl space (2 separate spaces in our house). We heard critter noises and our upstairs was hot in the summer. The insulation was original to the ~30 year old house, so we know it's about time to get it done. Alex checked both spaces and showed us photos of problem areas. We have an estimate and Alex explained the details of the work involved. The team came within the week (we lucked out to take the spot of a cancellation), and everything was done as expected. There was a lot of work to remove old insulations, vacuum all debris, sanitize the space, seal all air gaps, install baffles, rodent proof, and install new insulation. The work was completed in around 6 hours, the spaces are now clean and tidy - quite unbelievable given how they were before. We went for the heavier insulation which is reflected in the project cost."

"I was seeking a significant augmentation of insulation in my attic, since the existing insulation was 31 years old, and had become very thin, and shoved around over several decades of work up there. After vetting 4 contractors, I chose Western Pest Services, and was very pleased with the entire process. they did a thorough evaluation of the attic space, evaluated my plan to run the installation tube through a 2nd floor window, and confirmed that there are no pests in the space. I felt that the price was fair - and the technicians did a terrific job in less time than I had expected. Definitely recommend them!"

"Wow... just wow. I feel like the clock rolled back several years to the days when tradesmen where available, on time, skilled and affordable. Koala is a rare find. These guys have it all together. Sal is the sparkplug that makes it work seamlessly. He guides you in just what you need, and nothing you don't need. His estimates are detailed and very fair pricing. After consulting with Sal he was able to schedule the work in less than a week. The installation crew called ahead on the scheduled day and arrived exactly on time. Shawn led the crew of 4 techs who worked neatly and thoroughly, and cleaned up well. They did rim joist sealing and batt insulation in a somewhat complex situation where I have I joists adjoining the band board. They also did blown in fiberglass in the attic. For anyone considering insulation of any format I highly recommend Sal and Koala. And, the best part of this experience with the company....the total cost less than others who had rebate programs."

"We had a cracked ceiling and sagging ceilings in 3 rooms, and a portion of drywall hanging but off the nails, larry and his son, replaced the broken pieces and shored up the rest with drywall nails, and insulation, and in some cases new drywall. A dirty, difficult job, which had to be done two days in a row as it required furniture moved and painters to follow. He recommended a painter for us as well, which allowed us to set the whole thing up for one week of inconvenience, but got the job done. He and his son were pleasant as well which helped through this trying experience. Since this problem is uniform through our development we had seen where ceilings had caved in on others and were caving in slowly on the rest and wanted this done before anything fell down on us and hurt us or guest. Larry cut out two days to do 3 rooms, which allowed us to set the painter up for completion. We also had to bring in a electrician to shore up a ceiling fan now that the ceilings were set properly."

"It worked! We have a very old (1865) twin house with old stone wall with apparently no insulation. The kitchen got very cold and the closets were full of freezing dishes. They pumped in insulation material between the dry wall and the exterior wall and sealed up some joists in a storage room below. It worked and we are now snug and cozy.
The were very professional, punctual and knew what they were doing. They took time to explain the work and answer questions. The two young me who did the actual work were very polite and considerate.
Wish we had found and hired these people many years ago! Would definitely recommend highly.

"I had a leak upstairs in my 2nd floor bathroom which in turn ruined most of my first floor ceiling and floors. It was stressful and I was not sure what to do first despite my insurance covering the damages. Trying to find the right people was very difficult. After much research and multiple quotes, I decided to go with JA DRYWALL. From the first day Isaias came to give me the quote, to the last day his father, George finished the painting... JA DRYWALL did what was promised and more. After each day of work, house was cleaned and livable. All of the JA DRYWALL employees were professional and courteous. It is good to know that I was able to trust a company to do the work as promised without any worries. Thank you JA DRYWALL for making my home looking like it was before the leak... It looks like a brand new ceiling. Your work and professionalism is amazing."

Drywall Insulation questions, answered by experts

Plaster provides a durable, soundproof, and moisture-resistant finish compared to drywall.

While every home has its own unique needs, ceiling drywall installation typically follows a staggered or stepped pattern to enhance structural integrity and reduce the visibility of seams. Starting from one corner, sheets are placed perpendicular to the ceiling joists, with the ends of adjacent sheets meeting along the center of the joist. The next row begins with a half sheet, ensuring joints don't align vertically. This alternating pattern, combined with proper taping and mudding, creates a seamless appearance and strengthens the ceiling structure, minimizing the risk of cracks over time.

It’s always better to follow proven drywall repair tips and fix the seams that look bad. However, if you simply want to make them less noticeable until you have time to fix them, you can use paint. A darker color of paint makes bad drywall tape seams less noticeable than light-colored paint. Matte paint hides bad seams better than glossy paint does, too.

Applying spackle is a simple DIY project that most people can complete in just a few hours. Even homeowners who have little DIY experience can complete this project in an afternoon. However, if you're uncomfortable with the project or don't have the time, you can always hire a pro to help.

Your walls are likely cracking due to fluctuations in the temperature outside. Drywall tends to expand and contract when temperatures and humidity levels change, and this repeated movement can lead to cracks in your walls, particularly around door frames. If you have multiple diagonal cracks, you may want to have your foundation inspected, as cracks can also be a sign of a bigger issue.
