"I had a problem room that had little insulation. Cold in the winter. Hot in the summer. No attic access. Energy services group was able to drill large holes in the ceiling & outside wall and spray in insulation. Then plug the holes and spackle. Replaced canister lights with led ones. They explained to my wife what they were going to do before it happened. Then said what they actually were able to accomplish. Great communication. Quick to schedule. Cleaned up after themselves. A quality company"

"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

The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.

The cost to install drywall is between $1.50 and $3 per square foot, while shiplap installation costs between $2 and $7 on average. In most applications, shiplap installations cost more than that of putting in drywall. However, several ways exist to reduce shiplap prices, especially for small locations or accent walls, which can keep the total cost of shiplap competitive with that of drywall.

It is possible to apply plaster on the interior or exterior of your home, but we don’t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it’s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it’s usually the best option to achieve high-quality results.

If your home’s foundation shifts slightly over time, any seams in the drywall represent the weakest point in the wall, leading to cracks. If your home has significant changes in temperature and humidity, this can cause the drywall to swell and contract slightly, causing a crack at the weak point of the seam. If your drywall installer did a poor job securing the panels to the wall studs, this could cause a weak layout and cracks in the seams.

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.
