"It is rare these days to find a great company with good values. This is one of those instances; I cannot say enough, good things about the professionalism of the employees at the office and those that showed up on site to install wall insulation. They showed up at the beginning of the two hour window, which was fantastic and explained everything with upfront pricing. We even asked for additional insulation and they were able to accommodate. Our home walls are now insulated and we even noticed a difference right away. From the time of arrival to completion they were nothing but exemplary. Thanks again for running an honest and professional team! Highly recommend to anyone out there looking to insulate your home!!! Notability, they were well below other companies on pricing too!!!"

"Attic Insulation Lab worked at my house adding insulation to the walls in the garage and covered them with drywall. Their price was within our budget and we heard good things about them as well. Eran and his team of 3 additional workers did the whole job and they worked each day till they finished it. The office personal were good too. They were very flex with us in regards to the work hours and days. We do recommend this company and mainly Eran."

"Alpha insulation is a good choice. Their installation was great. The guys cleaned up all their mess. Which is a plus for me. Miguel was easy to talk to. I told him what I wanted done to my house and he gave me a great price for what I asked for. So I hired him. I would recommend alpha insulation to friends and family."

"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"I vetted several companies for this project and Insulation Commandos was by far the most thorough and professional. The installers and workmanship were top notch and the price was reasonable. Could not be happier."

"This business is great to work with! They showed up early and got right to work. They laid down protective plastic as we have blown insulation that gets everywhere. They installed attic and subfloor. I thought they would be here all day. They were down in about 3 hours. Quality work, professional and very informative and clean!"

"Fibers Insulation was extremely professional right from the first call. I chose their service from Angie’s Lust and within minutes Geovany responded. He came out on a Saturday to provide a quote and followed up days later. Members of the company were here at the designated time and did a stellar job! I insulated my garage to add better barrier for my garage to enhance a new AC unit to offset summer heat. Geovany followed up after the installation to ensure all went well. To ensure a better look, taping will be added to keep it looking great. I will recommend them to others in my gated community as I am very pleased with the result."

Drywall Insulation questions, answered by experts

There are several benefits to wet-sanding drywall, but the main perk is that it produces far less dust than dry-sanding. As a result, wet-sanding poses fewer health risks and makes less of a mess in your home. Plus, damp sponges are less abrasive than sandpaper, so there’s a smaller chance of scratching or damaging the drywall paper. Wet-sanding also creates a smoother finish than dry-sanding.

If you only have tiny holes in your drywall (for example, dents or nail marks), you probably won’t need a patch kit. Instead, you can plug the hole with a small amount of spackle. Once the spackle dries, you can sand the area and paint over it—just like you would in the steps outlined above.

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.

New plaster must be fully dry and cured before painting. The drying time for plaster ranges from 1 to 4 hours, but the curing process can take more than five days, depending on various factors, including humidity levels, temperature, the amount of plaster used, and airflow in the area. You should always apply primer before painting plaster.

Plaster is denser, harder, and more porous than drywall, so it absorbs moisture differently. This means you’ll often need more prep work, such as thorough sanding, patching, and priming with a high-quality bonding primer. Additionally, you may need more coats of paint to achieve even coverage. While the process takes more time, it helps ensure a durable and professional-looking result.
