"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."

"We had ARC Insulation out to our house for mold remediation and insulation installation recently. We would like to extend our appreciation and overall endorsement of their services. Adrian and Eleazar arrived at our house on time and promptly prepared the house for the installation. They took extra care to insure that the procedure would be completed safely, cleanly, and accurately. We were impressed with their professionalism, knowledge, and work ethic. Both employees were personable and displayed a willingness to perform a job which would represent the company in a favorable light. It is reassuring that there are companies which are committed to a high degree of professionalismâ ¦and ARC Insulation is one of them. We highly recommend them for those looking for mold remediation and/or insulation. We would not hesitate to use ARC Insulation again if the need should arise. An enthusiastic five stars."

"Daniel and his brother are very professional, know what they are doing and are great problem solvers and equally as important, really care about the work they are doing. They found that a bathroom vent was not installed properly and ended up going to Home Depot twice to hookup the vent properly. They did the right thing and got it done right. I will be working with Daniel and Mendieta Insulation again and I will refer them to family and friends."

"It went really well. Robert Carroll really knows his stuff. Hire this guy. I say that without reservation of any kind. Don't look any further, believe me, I did. This is the smartest guy. He is honest, dependable, offers fair pricing, and his team can do all the work. I got several estimates from A+ rated insulation companies, but Robert was more knowledgeable than the other companies. He was the only one to point out that my soffits were not vented. Apparently, my house was built on the day no one was inspecting. The builder never cut open the soffits. That meant there was zero airflow going through my attic. The attic fan could run all day, but without air to move, it would not do any good. Only Robert noticed this and offered a solution to fix the problem! I asked some of the other A+ companies if they would vent the soffits and they all said they don't do that work, but they would be happy to add more insulation, which would not fix the problem if the attic was not vented."

"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!"

"We reached out to Dan with the issue of freezing pipes and cold rooms in our old house. Dan inspected the house and proposed a plan to remedy these issues. Aside from the more traditional air sealing and insulation solutions, Dan also recommended insulating the area of our house above our soffit, which was difficult to access but that appeared to be a major insulation issue. I should add the other firms we requested quotes for did not identify this area in their proposal. I firmly believe the proposals from the other firms would not have fixed our issues. Dan worked for ~2 weeks on air sealing our attic and house, adding insulation to our attic, removing our soffit and adding insulation and reinstalling soffit. Work was done well and within budget and at a fair price. Dan is very easy to work with and takes pride in his work. We are very happy to report our pipes have not frozen and the cold rooms are no longer cold - would highly recommend Dan to others - he went above and beyond."

"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."

"We used Perma Seal for several big projects—waterproofing our basement and replacing our concrete back yard and sidewalks. We had drain tiles, sump pumps and a dehumidifier installed, along with extensive concrete work outside. We dealt with a variety of crews and found everyone to be very communicative, professional, and knowledgeable. They did great work and kept us informed at every step of the process. When we had a questions, they were very responsive. All in all, we'd recommend and use them again."

Drywall Insulation FAQs, answered by experts

Drying alone can take 1 to 4 hours to dry to the touch per plaster layer, but some types of plaster take several hours longer to dry. However, this doesn’t mean the job is done because plaster doesn’t fully harden until it cures, which can take a few days to a couple of weeks. It may take even longer if you’re building a new, pretty thick plaster wall. Allow the plaster to cure before painting it.

You can paint over plaster, but repair any damage to the plaster first, or the paint will crack and bubble. You should also prepare the surface of the plaster to accept paint, which gives your paint job the best chance of looking good and lasting a long time. Before applying the color you want, apply a coat or two of primer. Additionally, use latex paint, and choose a latex paint with a satin finish for areas with dampness, like bathrooms.

In some minor cases, you can DIY drywall repair with minimal time and money spent. This method is best when you have a hole made by a singular problem, such as accidental furniture moving, and not a continuous problem, like a rodent infestation. 

Knowing what product to use is crucial. For example, small holes only need spackle, whereas large holes might need a new piece of drywall. You can flex your DIY abilities on this project, but if you’d like a second opinion or have a more significant problem, it’s best to call in a drywall repair pro.

Deciding whether to repair or replace drywall can be tricky, but your top considerations should be the extent of the damage and what caused the damage. For instance, if you need to repair a small hole caused by a doorknob that hit the wall, you can safely patch it without a second thought. However, if you have significant drywall damage caused by water damage, it’s best to thoroughly remove the drywall to inspect and repair the pipes behind it before replacing it.

Both plaster and drywall are durable wall finishes, but they differ significantly in installation, cost, performance, and aesthetics.

Installation & Cost: Drywall installation is faster and more affordable, typically costing $1.50 to $3 per square foot. It uses premade sheets, making it a more accessible DIY project. Plastering is a labor-intensive craft that requires specialized skills, pushing costs to $2 to $10 per square foot. It involves applying a wet paste over a lath framework.

Durability & Performance: Plaster is generally more durable, longer-lasting, and provides superior soundproofing. It is also a better insulator, which can help reduce energy costs. Drywall is easier to remove for future renovations.

Aesthetics: Drywall provides a smooth, uniform surface ready for paint or texture. Plaster offers a high-end, naturally textured look that can hide imperfections and is often preferred for achieving a classic or historic aesthetic.

Which is better? The choice depends on your priorities. Drywall is ideal for those prioritizing a lower upfront cost, faster installation, and DIY potential. Plaster is the better option for a higher-end project where durability, soundproofing, and a unique, premium finish are more important than the initial cost.
