"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"Tempest insulation with Fernando are going to be my go to team for any future insulation needs. I used tempest for a R44 blown in insulation. Fernando was on time for the estimate, sent me a follow up with responses to all my questions and began the work at 8 am on the dot! He and his crew were timely, professional, clean and were in and out of my place in less than a day and cleaned up everything after themselves. I would highly recommend them!"

"I was referred to this company from a friend that used them in the past. I needed to remove part of drywall and replace the insulation inside due to a leak from one of the pipes. At first I called the office and told them what the problem was. The office sent Juan to my house to check and see the job. Juan came over the following day and looked the problem. He was able to give me a quote on the spot. 
The price seem to be fair so I hired them for that job. Juan than scheduled me for 2 days later and he told me that it will take 1 day to complete and another day to paint. 
I was happy with the fact that he came over when he said he will and he did complete the job the same day. The paint work was completed the following day and I?m happy with the results.

"Every person that came into our home from Tri-County was very professional and respectful.  They covered everything with plastic before removing the insulation and again when blowing it back in.  They cleaned up and disposed of the plastic, vacuumed the attic and cleaned up after themselves such that  you would never have known they were here.  The job of sealing the attic was done so well that the inspector made a comment that he had never seen a job done as well as this and ask who had done the work.  He gave them very high praise.  

The salesman we had, Bryan Zailer, was very knowledgeable and helpful.  He would call back immediately if we had a question and stop by to check on things.  I would highly recommend Tri-County to everyone for their insulation needs."

Drywall Insulation FAQs, answered by experts

The tool you use to sand plaster will depend on the size of the project. If you’re just working on a small section of your wall to get rid of an uneven spot on the surface, hand-sanding might work. However, for larger projects, a drywall sander can make a huge difference when it comes to both time and elbow grease—and an orbital sander can help for detailed areas such as around ceiling fans.

If you're comfortable hanging drywall yourself, you may be comfortable finishing it. But it's worth noting that finishing drywall adds several steps to the process and a lot of waiting time. Hiring a drywall installer may be the way to go if you'd rather spend your time doing other things or are nervous about leaving a rough surface.

Venetian plaster is a highly durable wall finish that becomes a rock-like substance once dried, making it last longer than most other wall finishes. Its lifespan can range from decades to centuries, potentially lasting a lifetime. Key factors influencing its longevity include the quality of the initial application, whether it's properly sealed against moisture, and how the wall is maintained and treated (e.g., how often it is touched or bumped). Due to its mineral content, it can also develop a patina over time.

If you suspect black mold is inside your walls, do not punch a hole in the drywall yourself to look. Call a mold inspection expert to help you. Some signs of a potential black mold infestation inside the wall include an unexplained musty, damp smell. Some people liken it to rotting vegetables. You may smell it most strongly through a wall outlet. If you and your family are experiencing constant coughing or symptoms that feel like an unexplained allergy, it could indicate black mold behind a wall.

Plaster can be a difficult DIY to master, especially if you plan to plaster an entire room, rather than patch a small area. Before you begin a plaster DIY project, you need to know which tools and type of plaster to use. It's also important to know how to prepare the surface and apply the plaster for a smooth finish. If that all sounds like a lot of work, you may prefer hiring a local plaster repair contractor to do the job.
