"We’re building a new 1000 SF home and these guys did a great job. Easy to communicate with, showed up when they said they would and knocked the entire job out in a day. City insulation inspection passed without any issues the next day. SPF was even kind enough to upgrade to higher R-value insulation in some of our 2x8 walls at no added cost. Highly recommend!"

"I was given several recommendations from Angi list, the most professional one of the 4 contacts I received was from David of EVERGREENPRO INSULATION. I needed to have a couple of interior walls insulated for soundproofing done. David was responsive, answered all my questions and gave me a reasonable quote. The other companies I talked to quotes were inline with Davids but the customer service just wasn't there like Davids. I even had one company tell me my project was too small for them to do..... Really? The next insulation project I need done I will just call David from EVERGREENPRO INSULATION and give them the job. A great job done by David and Jamie and would recommend and use them again."

"I recently hired HM insulation to help clean up from a leaky pipe and put new insulation in as well as insulating the pipes. They were very knowledgeable and knew just what to do. I highly recommend them for quality and going beyond to help with whatever issues we had. Prices are excellent and their crew was very helpful and cordial. We will hire them again if we need any other place insulated! Thanks guys!!"

"I've worked with many companies over the years doing upgrades to veterans homes and other home insulation projects but this company really stood out above the rest. Absolutely exceptional! Professional, high quality, competitively priced and his team did the work beyond my expectations. Completely removed old, contaminated insulation, treated the entire attic to remove mold and other contaminates and then replaced with top quality insulation "to code." I'll be recommending them for any future projects when restoring homes."

"Sergio and his crew timely completed a complex insulation installation. Near Me Insulation LLC gets highest marks for flexibility in terms of traveling from Burlington to Glacier and completing the work with the highest skill level. The inside of my Ski Barn in Glacier has a height of 35 feet at the peak--several rooms with outside walls needed insulation. Sergio and crew also wrapped pipes and replaced window flashing with great care and expertise. Highly recommended contractor--reasonable price."

"I had insulation blown in between my floor joists supporting the main floor of the house. Installation was timely and meticulous. Mesh fabric was installed tight and secured with staples driven in with an air gun, evenly spaced 1 inch apart. Insulation blown in, filling the space between the joists and every crevice. The fabric gave my cellar a finished look, resembling a drywall ceiling. They left the job clean and better than when they started. They used top-of-the-line materials, tools and equipment. I highly recommend Proficient Insulation Solutions."

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.

Most drywall used for interior walls of homes is 1/2-inch thick. This size strikes a balance of being easy to handle and hang while being thick enough for the durability needed on interior wall applications.

For maximum stability, install grab bars on wall studs, as this will adequately support the weight. However, if you don't have access to studs, you can get by with wall anchors. If opting for the latter, choose specialty hollow wall anchors. 

Yes, you can put paneling over textured walls. Of course, this will come down to personal preference and the type of paneling you want to install. From board-and-batten to shiplap and wainscoting, there are plenty of options to choose from.

A jigsaw is commonly used to cut holes in drywall. It offers versatility and precision, making it suitable for creating circular or irregular openings. When equipped with the right blade, a jigsaw can swiftly and cleanly cut through drywall, making it a good choice for DIY projects.
