"Standard Insulating Company sent David E to our house to a**** a problem we were having with hot spots in certain areas. David was up front with his assessment and explained everything in a way we were able to understand. The quote he emailed us was surprisingly reasonable with no hidden fees or surprises. We chose to have our insulation capped as well as radiant barrier installed. The work was scheduled less than a week later and the crew was professional, knowledgable, quick, efficient and kept the whole work area clean. I highly recommend Standard Insulating Company to anyone looking to have any type of insulation work done."

"The guys arrived on time to add insulation to my attic. The work was explained to me and completed in a professional manner. It had been suggested by Duke Energy’s audit that insulation had compressed."

"Needed a solution for a room above a garage that was hotter than the rest of the upstairs. It was recommended to add insulation to the garage ceiling, air seal the attic, and add additional insulation to the attic. Since then, the room above the garage has been the same temperature as the downstairs. Great work and wonderful solution. Price point came in on average $1000 less than most quotes we received."

"Behr was fantastic! Nick and Dakota were extremely professional and provided a fair quote. They removed the old insulation, installed new insulation in my attic, and sealed all the gaps to help improve my heating efficiency. I have nothing but positive things to say about their work."

"From the initial visit with the salesman to the production coordinators to the project managers to the boots on the ground (or roof) my experience with Home Genius Exteriors has been amazing! Tony, the Project Manager, is incredibly knowledgeable and personable. He took the time to walk me through every phase of my roof and siding replacement. He was very responsive, even during off-work hours. He addressed every concern I had and was thoughtful in his responses. He was very thorough when conducting inspections, identifying action items I didnâ t see, even if it meant additional work for his field crew at no extra cost. I canâ t say enough about the field crews for both my roof and siding replacements. They were incredible and they didnâ t treat my house as â just the next jobâ . They catered to my houseâ s needs, worked extremely efficiently, and did everything I asked of them. I would highly recommend Home Genius Exteriors for roof, siding, and gutter needs!"

"I called GSM inquiring about their HVAC and insulation services. I also asked if I could have someone perform a Manual J load calculation (surprise to me, the Manual J calc was free!) as I felt that my existing heat pump was sized too small for my home (2.5 ton dual-zone single stage heat pump for 2200sq ft 2-story house). We agreed on an appointment time, and they sent Kelly out to my house. Kelly was very nice and professional, and did a thorough job explaining what all could be done and what my options were. Due to having so little room to work inside of the mechanical closest, you would have to remove the air handler completely just to wrap all of the duct work. Since I would be removing the old air handler that was 8 years old anyway, I decided to replace the entire system with a new Amana 3-ton 18 SEER dual-zoned heat pump. Kelly also told me they could seal up the hole & the mechanical closet so that hot air could no longer enter that space as well. I agreed to their quote, and they came out a week later (it would've been sooner but GSM wanted to make sure that the new system was designed properly, so they had to architect and design the layout of the new equipment to fit the small space) to do the work. Owen and Jason came out to perform the installation. They were both very professional & thorough, and they did an excellent job with the swap out & installation of the new heat pump. When GSM told me that it would take two days to do the work, I was prepared to be miserably hot trying to sleep at night with no air conditioning. Not only did GSM bring a portable AC unit for me use that evening so that wouldn't be the case, Owen and Jason actually got the heat pump wired and working the first day so I had full AC that evening, and the portable unit wasn't needed! They also insulated the attic space & mechanical closet with spray foam and foam board so the hot attic air will no longer be an issue. All in all, my experience with GSM has been great! They've been easy to communicate with throughout the entire process, they did an excellent job with the installation of the new equipment, and now I can rest easy knowing that everything has been taken care of!"

Drywall Insulation questions, answered by experts

Depending on the place where the cutting error occurred, you may be able to fix it. Learning how to patch a hole in drywall is challenging, but if you can tape and mud drywall, you can do it. Having said that, patching is time consuming. Early in the installation process, you may find that it’s easier and far less time consuming to just start over with a new sheet of drywall, cutting a new hole in the right spot. You may be able to use part of the incorrectly cut piece elsewhere, so it’s not completely wasted.

If you want to reduce sound transmission throughout your home, soundproofing drywall is a better choice than standard drywall. However, simply installing soundproofing drywall may not completely block out noise. You’ll get the best results from incorporating it into a larger soundproofing plan that includes proper insulation and framing studs.

While it’s most common to sand plaster dry, it is possible to wet-sand plaster, too. Doing so can reduce the amount of plaster dust released into the air and make it easier to work in smaller, more delicate areas (such as around wall trim). However, some people find that wet sanding leads to more imperfections, which is why larger walls are more often dry sanded to ensure an even finish.

You should stagger drywall sheets to help prevent cracking. The joints between drywall sheets are the weak spots, so if you install drywall with seams aligned, you’ll create weak lines that run across the length of the wall and extend from floor to ceiling. But when you stagger drywall, the solid sections of panels will support the joints. This can prevent seams from cracking or separating due to fluctuating temperature and humidity, vibrations from movement inside the home, and gravity.

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.
