"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."

"From the initial visit with the salesman to the production coordinators to the project managers to the boots on the ground (or roof) my experience with Home Genius Exteriors has been amazing! Tony, the Project Manager, is incredibly knowledgeable and personable. He took the time to walk me through every phase of my roof and siding replacement. He was very responsive, even during off-work hours. He addressed every concern I had and was thoughtful in his responses. He was very thorough when conducting inspections, identifying action items I didnâ t see, even if it meant additional work for his field crew at no extra cost. I canâ t say enough about the field crews for both my roof and siding replacements. They were incredible and they didnâ t treat my house as â just the next jobâ . They catered to my houseâ s needs, worked extremely efficiently, and did everything I asked of them. I would highly recommend Home Genius Exteriors for roof, siding, and gutter needs!"

"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 FAQs, answered by experts

You can skim coat plaster, but it’s better to repair the plaster itself. A skim coat is a thin coat of drywall joint compound spread over the surface of a wall. The result is a flat finish that looks pleasing, but part of the appeal of plaster is its imperfections and aesthetic. Skim coating is best when limited to drywall applications.

You should not leave drywall outside, especially overnight or in a wet, humid climate. Exposure to rain and humidity can damage the drywall, weakening its structural integrity and making it susceptible to mold growth. If you must leave drywall outside during a project, be sure to cover it with a tarp or keep it inside a storage shed to protect it. Even drywall intended for exterior projects requires a protective moisture barrier. For best results, store any extra drywall in a dry area away from the elements.

In most cases, no, you won’t need a permit to replace drywall. If you’re changing the floorplan of your home by adding or removing walls during the drywall project, then you might need a permit, but replacement or repairs usually doesn’t require a permit. Your drywall professional should be able to confirm whether or not a permit is required for your project. If it is, it’s likely to add between $50 and $150 to your total cost. Keep in mind that you will need permits if you plan to install new electrical wiring or plumbing lines behind your new drywall.

Cracks, water damage, and holes from fixtures or impact.

The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.
