"I could not have been more pleased by the work and the professionalism and the cost and the results. ABI was the first company to respond to my request for bids on the project. They were at the house within days of the request and were knowledgeable about putting insulation over light fixtures embedded in the ceiling. The attic did not have access from within or outside the house and they problem-solved this in a way that was a great solution. They lay down mats so as not to dirty up the carpets and stairs and they wore gear to protect themselves from the insulation. MY house was cleaner when they left than when they arrived. All of the people working on the project were professional and knowledgeable and the cost was extremely reasonable. For the first time this winter, my house feels like it can hold the heat. Looking forward to this summer, because I'm betting it will also improve my air conditioning!"

"Quality Insulation of Portsmouth did two jobs for me: They added blown in insulation to my attic last fall and installed gutters plus leaf guards this spring. Both jobs were excellently done at a reasonable cost. I would certainly recommend them and will likely use them again in the future."

"I was plagued with recurring ice dams in a few areas of my roof. After investigation, it was discovered that the insulation in a few visible areas was sub-par. Roland came in and quickly spotted the problem areas. He assured me that the could fix these problems immediately. He used a combination of rearranging existing batts, blown-in fiberglass and spray foam to seal the attic space, over the course of two visits. He's extremely personable and always called me back or answered the phone right away."

"I would highly recommend Jeremy for any home renovation needs. He is my go to contractor for anything I need done around my rental property and home. His attention to detail, punctuality, professionalism, and honesty sets him far apart from many other contractors I’ve worked with over the years. Jeremy has helped me with drywall (replacement and finishing), flooring, trim, and priming an entire unit for a repaint! Each time it was a pleasure working with him, and will definitely be working with him again in the future."

"We put off doing this project for a long time because it was a major renovation and we were worried about making the right decisions.  We were fortunate to find Todd because his combination of experience and professionalism was exactly what we were hoping for.  Todd was great to work with!  He had good ideas, helped guide us to make kitchen design choices, and asked for our input on every aspect of the project. We could not be more pleased with our new kitchen!

Drywall Insulation FAQs, answered by experts

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.

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.

There shouldn’t be any gaps between your walls and ceiling. These can be fixed with joint compound but that is only a fix, and it’s much better if your drywall fits correctly in the first place. Sometimes gaps can appear if your foundation shifts significantly but if this is the case, you have a much bigger problem than patching drywall.

While fumigation chemicals cannot pass through solid objects, they will seep into any openings in walls, doors, or other closed spaces. This allows them to get into tight places where pests may be hiding and causing damage, like termites ruining the foundation of your home. It also means that your home needs to ventilate for 48 hours before returning to ensure that no harmful chemicals remain in your space. 

Yes, as drywall mud is going to have some uneven spots and bumps after application. Such imperfections are going to be visible after everything dries and even after you paint the wall, so you want to remove them. Learning how to sand drywall, taking your time, and following drywall sanding tips can help you have the best results.
