"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

"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."

"Unfortunately, when the techs started the process, the insulation already in the walls prohibited the addition of the foam. I cannot begin to tell you how disappointed I was, as the job they had done on our tiny addition was remarkable. However, isn't it wonderful to have a company tell you the truth!"

"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 that sags or bulges, shows extensive deep cracks, or is crumbling from water damage or simply time may need replacement. Plaster walls can look a little “worn” for a long time before they need replacing. The only real way to know if it needs a replacement is to hire a professional to assess the condition of the plaster.

Plastering and skimming are two different techniques for finishing walls. Plastering involves applying a thick layer of a plaster mixture—typically containing gypsum, lime, cement, sand, and water—to create a new surface. This process often requires multiple coats and is used for repairing significant damage or creating decorative textures. Skimming, on the other hand, is a technique that involves applying a thin layer of drywall compound or joint compound over an existing surface to smooth it out, covering minor imperfections, small cracks, or uneven textures for a polished look. Plastering is generally more costly and labor-intensive than skimming. Although some people use the terms interchangeably, they refer to different processes and materials.

Certain drywall textures, like sand and sometimes popcorn, can be smoothed by applying skim coats, sanding the walls, or chipping away the texture. However, it’s worth considering removing the texture and starting with a blank canvas. Smoothing textured walls requires a lot of sandpaper and elbow grease and can take longer than just outright removing the texture.

You can technically just paint over hairline cracks in plaster since these cracks are often harmless, but this will mostly be a waste of paint. Paint will only hide the hairline crack for a few months before it shows up again. The best solution is to repair the crack with flexible filler or joint compound before repainting.

You should leave a gap between drywall sheets because they naturally expand and contract along with the building framing as temperature and humidity change. Most pro drywall installers leave a gap of about ⅛ inch between drywall sheets, allowing the sheets to expand, contract, and shift without cracking or becoming damaged. If you don’t leave enough gaps between slabs, the edges will press against each other when they expand, and the pressure can cause visible cracks.
