"We badly needed insulation in our attic. We got three quotes. Weather Shield was not only the most reasonable, but the only company in which the owner both gave us the quote and installed the insulation with colleague. We could not have asked for more professionalism or better service. Would highly recommend Gus."

"We needed to rehab a family member's attic and crawlspace that had no ventilation and mold/moisture as a result. Jay came in and based on his experience, he assessed exactly what was needed to fix all of the problems. His team came in and created proper ducts for the kitchen and bathroom vents, cleared all of the soffit vents, added more roof caps, added baffles, removed all of the old insulation and added new insulation (to R49) and removed ALL of the mold. Looked like a brand new attic! His team also removed all the mold in the crawlspace and placed a vapor barrier down there, and covered all of the walls with foam insulation - problems also fixed in crawl. All of this was completed at a reasonable price. We were so pleased and impressed with ARC's work that we had our own attic worked on. The ARC team assessed my home for proper ventilation and insulation and worked magic in the attic (added soffit vents, baffles, sealed all gaps, raised insulation levels to R49) and added new roof caps. While the crew was working on the attic, they noticed that the ceiling drywall had detached from the attic joists (and informed me that the drywall was sagging). Rather than blowing it off as someone else's problem, not saying anything and just adding the insulation (which would have made the ceiling cave into the house), his team spent 6 extra hours adding screwing the drywall back in place (raised ceiling 1/2" back up. I can't thank them enough for catching this and informing me. Their honesty and integrity impressed me, along with their expertise and knowledge of proper ventilation and insulation. Both levels of my house are now the same temperature and my furnace is working less to heat the house. I can't thank them enough. ARC's team kept me informed each step of the way during both jobs, they were extremely quick in their responsiveness and were professional and on time during both jobs. Thanks Jay - we are sending more referrals your way."

"Jim Clay gave the most comprehensive quote for our insulation project. He suggested a couple of options which thought would help regulate the temperature in our home. He explained everything that ARC insulators would be doing to our home. He told us about rebates that would be credited to our bill because of a blower door pressure test and gas appliance combustion test. He presented a well-written quote. The technician for the tests and the technicians who did the insulation work showed up on time. They explained everything they were doing thoroughly. When the work was done, we did a thorough walk-thru before the techs left. We are satisfied with the work performed. We are satisfied with the money we paid. We would recommend ARC Insulation to anyone seeking recommendations."

"Alex and his team were prompt and they did a very good job on the insulation project. The team worked well together and they were efficient. They picked up the trash in the attic before blowing the new insulation. The work was done with complete satisfaction and I highly recommend this company. Keep up the great work!"

"I am very happy with the work done by Green Attic Insulation. David and Charlie were very friendly, professional, responsive, and flexible in working with my changing needs. I originally was looking into insulation but then discovered there was mold in my attic. As the job grew, David, Charlie, and their team worked with me to address the additional parts of the job. I really appreciate their knowledge and the thorough job they did. They took many pictures of their progress and kept me informed each step of the way. Thank you very much!"

"I have dealt with several home improvement companies and individuals. Home Genius Exteriors was a breath of fresh air. They were pleasant and professional from the initial phone call and meeting to the installers. They presented all of the information, answered all questions and everything was done within the window of time that we discussed and agreed to. I am very pleased with the results. The color match was perfect and the installation was efficient and neatly done. I highly recommend this company."

"I'm proud to hear my son, Robert Wolfrum, is working for Perma-Seal. I first used Perma-Seal in the 80's for a foundation crack repair in our South Holland, IL home and then again at our Tinley Park, IL home. Both experiences were memorable and professional and fixed our basement water problems. It is good to know that my son is working for a reputable company that has been doing quality work for decades. I was surprised to hear that they do insulation and concrete leveling."

"The Home Genius Exteriors team does excellent work. From the initial quote to the final walk through they are professional, patient, and, perhaps most importantly, available. I'm not completely "roofing naive" and I can say that their craftsmanship is top notch. They are a bit pricey in my opinion BUT I believe it to be a "you get what you pay for situation." You will certainly be in safe and certain hands with Mike, Walter, Luis and company. I would 100% keep them in mind for future projects."

Drywall Insulation FAQs, answered by experts

You should not leave drywall outside, especially overnight or in a wet, humid climate. Exposure to rain and humidity can damage the drywall, weakening its structural integrity and making it susceptible to mold growth. If you must leave drywall outside during a project, be sure to cover it with a tarp or keep it inside a storage shed to protect it. Even drywall intended for exterior projects requires a protective moisture barrier. For best results, store any extra drywall in a dry area away from the elements.

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.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.

Drywall insulation costs around $1,800, on average, but prices can range from $500 to $4,500, depending on a few different factors. The following things are important considerations to make when pricing out your insulation project:

  • Square footage of insulation

  • Type of insulation 

  • Climate in your area and the insulation R-value required

  • Whether or not your walls are already finished

  • Accessibility of the area 

  • Whether or not you need old insulation removed first

To properly clean and maintain your skip trowel drywall texture, dust the surface weekly with an electrostatic duster or vacuum with a soft brush attachment. Never scrub the surface. You can remove stains by gently applying a mild detergent solution with a paint roller, removing it with a damp roller, and drying with a dry roller. To cut down on cleaning frequency, avoid indoor smoking and limit the use of fireplaces.
