"I needed insulation put into existing walls without any remodel. They came and did blown in fiberglass from the exterior walls. They did a great job and were super friendly. Some issues came up during the job with my interior drywall because the sheetrock was installed incorrectly. They didn’t hesitate to come in and fix the problem. They cleaned up after themselves before leaving where you couldn’t even tell they were there. I noticed an immediate difference in sound and comfort in the house. I am very impressed with how friendly and professional they were. The job was quick and effective. Highly recommend."

"Everything went according to plan. Crawlspace insulation was replaced and closed space was sealed up. A air inducer was also installed. The environment is totally different down there now and is much closer to the temperature of the house. I kept my vapor barrier the same."

"Insulation Commandos insulated my garage drywall, and I had a great experience working with them. Tony was especially helpful in explaining the available options and recommending the solution that best fit my garage and specific needs. He was knowledgeable, professional, and even managed to fit me into his schedule on short notice, which I greatly appreciated."

"I had recently bought a house and wanted to know if my upstairs insulation was doing its job. I found Koons Crawls Space Solutions through Angie's List. Literally within minutes of requesting a quote, Tim got back to me. He was able to come out the same day and check out my attic insulation. He was by far the fastest to respond. Unlike the large well-known company that first gave me a quote, Tim gave me his honest opinion that my current insulation was fine and we didn't need more. He showed me how the big-name company was looking to make some money rather than address my personal needs. I still had him quote me what it would cost to do the same work the larger company quoted, and Tim's price was significantly less. I highly recommend Tim from Koons Crawl Space Solutions. He saved me thousands!"

"MGs Roofing was absolutely amazing to work with from the start! Mike and Matt did all of the leg work for us from inspection to contacting insurance to installation and follow up. Prompt, reliable and professional. In these busy times, it is much needed and refreshing and the model for conducting excellent business! We had a new roof within a week! All work completes in one day. I work from home and besides some hammering, hardly knew they were hereâ ¦. and the outcome is a stunningly beautiful, great quality, architectural shingled roof that adds beauty to our modern farmhouse. The process was simple yet professional from beginning to end. Thank MGs Roofing for our amazing new roof. Pics here donâ t do it justice! Swing on by and have a look. 5701 Cornwallis Road in Garner, NC. Highly recommend MGs Roofing for all your roofing needs!"

"We recently worked with Evergreen Foam & Insulation on a new construction project where they applied spray foam insulation to the walls and roof deck. Their team was professional, efficient, and maintained clear communication throughout the process. The quality of their work met our expectations, and they completed the job on schedule without any issues. The attention to detail during application was excellent, and the site was left clean and ready for the next phase of construction. We’re pleased with the results and look forward to working with Evergreen Foam & Insulation on future projects."

Drywall Insulation questions, answered by experts

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.

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.

Applying spackle is a simple DIY project that most people can complete in just a few hours. Even homeowners who have little DIY experience can complete this project in an afternoon. However, if you're uncomfortable with the project or don't have the time, you can always hire a pro to help.

Yes, you can use drywall repair techniques for some types of plaster damage. Tiny holes and small cracks in plaster can be patched in similar ways to drywall. You apply the necessary compound to fill the hole, wait for it to dry, then sand it down. For larger damage, like water damage or mold, you need to use plaster-specific techniques and materials.

With its breathability and flexibility, lime plaster is among the most durable of all plaster types. It's also fire-resistant and has a proven track record, as people have been using it for thousands of years.

However, all plaster types will last for many years with the right care and treatment. Proper preparation and installation will also help ensure your plaster walls look great for as long as possible.
