"Excellent. The JE Mountain team was professional, timely, and did great work on the timeline they promised. Then cleaned up after themselves. They did both spray and batt insulation for me and I recommend them without reservation. They’ll definitely be my first call for my next project."

"We were remodeling our basement for a rental apartment. While we had all of the drywall removed we decided it would be a good idea to sound proof the area for privacy. I did some research online and found a system and company that sold soundproofing supplies. We completed some of the work but we ran into a time crunch and decided that we needed to hire someone to help us finish. Freeman Insulation and Construction and Insulation replied promptly and was very friendly. They agreed to come out at a time that fit my schedule to go over the project in person. When they came out they were familiar with system and had no problem reviewing the instructions of the supplies I had purchased and even provided me with additional suggestions to improve the performance of the soundproofing that I had not even considered. They came back with a quote that was very reasonable after taking the time to find the best deals in town on the remaining supplies required for the project. They completed their work with no delays. The thing that set this company apart from every one else is when they came by to check up on my project and helped clean up after a messy drywall company (not affiliated with Freeman Insulation and Construction) to help me meet my deadline. This was above and beyond my expectations. Overall their communication was excellent, they were friendly, professional and courteous. The end product was better than I expected and most important, I have a happy wife at the end of the project. A huge thanks goes out to these guys for making this the smoothest part of my project!"

"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

Drywall anchors won’t work on plaster. Instead, they will more than likely cause more damage and pull out the plaster. The best type of anchors to use on plaster walls are the ones that will bite into the surrounding area, such as molly bolts and toggle bolts. Masonry anchors with expanders on the sides also work for lighter pictures.

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

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.

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.

There are six levels of drywall finish, from 0 to 5, that refer to the amount of work performed during the finishing process.

Level 0: Drywall is hung with no finishing work.

Level 1: Tape is placed over the seams between drywall sheets.

Level 2: A thin layer of mud is applied over the tape and screw holes. This level is common for utility rooms or walls that will be covered.

Level 3: A full coat of mud covers the screw holes and tape, but the surface is not sanded. This is often used in garages.

Level 4: This is the most common finish for visible interior walls. It involves applying two coats of mud over seams and screw holes, with sanding between each coat, creating a smooth surface ready for flat paint.

Level 5: This is a high-end finish for luxury homes. It includes full taping, mudding, and sanding, plus a final skim coat over the entire surface before painting.
