"I recently had the pleasure of working with H&L Insulation that was hired to blow fiberglass insulation into my attic, and I couldn't be more impressed with their professionalism. From the moment he arrived, he was punctual, courteous, and well-prepared. David took the time to explain the process to me and answered all of my questions patiently. He worked efficiently and meticulously, ensuring that every corner of the attic was properly insulated. He also made sure to clean up thoroughly afterwards, leaving no mess behind. Overall, his attention to detail and commitment to quality were outstanding. I highly recommend their services to anyone in need of attic insulation!""

"Claudio and his team did the blown insulation in my attic today and they did an AMAZING JOB; I am very happy with their work. He is very professional and answered all my questions from start to finish, he arrived at the time he said he would and cleaned up to a point that you would not even know they were here. :) I would most certainly refer them I would give 10 stars if I could. I got two other estimates, and his price was by far the best!"

"This company beat the socks off another company I considered. For one fee, Green Energy removed ALL the blown in and batt and rolled insulation. On the second day, they installed the spray foam. I had another contractor look at the job - and he said he wished he had hired them for his house. If Green Energy had a yard sign - because I would proudly display it. Sweet people and an excellent job. So glad for this recommendation."

"Kendrick and Allen installed blow-in insulation above a bedroom ceiling in my condo in May-2016. These two guys were polite, prompt, professional and cleaned up when they were finished. I feel like I got a fair price for a very provfessional job. I would highly recommend calling them for insulation work.."

Drywall Insulation FAQs, answered by experts

The best tool for skim coating drywall is a skim coating blade, which can smooth out joint compound in wide stretches. While you could use a smaller drywall knife for skim coating, the smaller size means it’ll take longer to smooth out each section. Instead, consider investing in a skim coating blade for the quickest application.

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

If your home was built before the 1940s and was not remodeled in the past 50 or so years, you probably have plaster walls. Aside from assuming, there are some practical ways to tell if you have plaster walls, including the following: If you knock on the wall and it feels solid, not hollow, if you can’t insert a thumbtack easily, if there are cracks that look like spiderwebs, or if your home has curved, arched, or swirled walls, doorways, or window openings.

If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.

Plaster walls typically last between 30 and 70 years, but depending on the quality of the materials and the moisture levels in the building, they can last for over 100 years. With expert application and consistent maintenance, plaster can even last for centuries. To extend its lifespan, it is important to have the plaster professionally installed, address any water damage promptly, and repair small cracks as they appear. Regular inspections by a professional can help identify and address concerning cracks before they become significant issues.

If the holes in the plaster are small, you can fill them with layers of patching plaster until they’re filled. After it dries, you can sand the plaster and paint over it. If the hole is much larger, consider using bonding plaster first and then a layer of patching plaster, completing the process with sanding and a layer of paint.
