"Amazing response and amazing job done, in a short amount of time. I have known for awhile that I needed more insulation in the attic. I started to search for insulation companies in the area. I quickly started seeing a pattern with reviews on other companies. All of them were, "called 15 times, never called back", "agreed on a start date but never showed up", "showed up but didn't know what was needed"... I was dreading making any decision on who to call. But then finally a company stood out above all the rest, Energy Nerds. I called Mike and left a message. He called back within an hour and even apologized for not calling back sooner! What?!? I called him on a Friday afternoon, he said he would be out Sunday afternoon and the job was completed by that evening! Truly amazing work done in a short amount of time. Mike and Dustin are great friendly people. Very knowledge in cutting edge technology to help you save money with energy costs. Mike is well informed so if you have any other energy saving needs, please talk with him. I would not hesitate to hire them again. Truly a pleasure to work with."

"Prompt callback to set up a inspection of our attic needs. Was super knowledgeable and explained the differences between the different blown in materials we could use. When he came to blow in the extra insulation, he was efficient and got it done in a very reasonable time and cleaned up all messes. Very friendly and polite contractor! Will recommend to everyone! Thanks for the great service you provided!"

"The installers were careful, courteous, & thorough. They left the premises clean & uncluttered. I can't wait to see the difference in our heating bill. They installed spray foam in the rim joist, a small ceiling in the basement & the walls in a crawl space."

"We needed our attic insulation replaced after the 2020 derecho. McKee came in as the lowest bid with better quality (higher R value) than 2 other local companies. They also spotted some roof issues that the other companies did not and we were able to get that fixed prior to McKee starting the insulation job. Weston and his crew were fabulous during the work, being very respectful of the fact we are still working from home. McKee also recommended some improvements (canned light and speaker covers as well as access hole covers) to further improve our overall rating. Install and cleanup were both top notch I would highly recommend McKee for this type of work!"

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Drywall Insulation FAQs, answered by experts

To hide drywall edges, you need to properly apply drywall tape and multiple layers of joint compound. These materials hide the seams between drywall sheets and fill the holes from drywall screws, leaving behind a smooth, flat finish to paint over. Apply joint compound smoothly, and finish the job by sanding the walls to make sure you fully hide drywall edges and other imperfections.

There are a few ways to figure out if your walls are plaster or drywall, but the pushpin method is probably the easiest option. To try it, choose a part of your wall where you can insert a pushpin or thumbtack without leaving an obvious mark. If it goes in easily, you have drywall. But if the wall is tough to penetrate, that’s plaster.

Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

The age of your home can clue you in to whether you have plaster or drywall ceilings. Homes built after the ‘70s are more likely to have drywall ceilings and walls, while older homes have plaster. You can also do the pushpin test: A pushpin will go into drywall, whereas it’s much harder to push one into a plaster wall. If you’re still unsure, ask a drywall professional to let you know which type of ceilings and walls you have.
