"Attic Fanatics did an outstanding job from start to finish! The team was professional, punctual, and explained every step of the process clearly. They removed the old insulation, sanitized, sealed air leaks, and then installed new insulation — everything was done with attention to detail and care for our home. What impressed me most was how clean they left the job site and how much cooler and more comfortable our home feels now. They even shared before-and-after photos so we could see the difference in our attic. It’s rare to find a contractor that goes above and beyond like this. I would highly recommend Attic Fanatics to anyone looking for attic insulation or ductwork — you won’t be disappointed!"

They explained all my options clearly, offered fair pricing, and followed through on everything they promised. The crew worked efficiently, respected my home, and completed the job exactly as scheduled. They also helped me secure an FPL rebate, which was a huge added benefit and showed how knowledgeable they are about available energy‑saving programs. Overall, the service was smooth, honest, and high‑quality. I highly recommend them to anyone looking for reliable insulation work."

Drywall Insulation questions, answered by experts

Choose a drill bit that is the size of the screws of the anchors you will use. You aren’t drilling through metal or concrete—hopefully—so any standard twist, wooden or all-purpose drill bit will work fine. It’s also important to have a screwdriver capable of drilling through the drywall and into the stud. The good news is most available drills, even the older ones, can do this with no issue.

You can put certain types of plaster over other types, but doing so isn't always the best idea. For example, putting a coat of gypsum over lime plaster is possible, but doing so will limit the lime plaster's breathability and potentially affect its performance.

Since cement plaster tends to leave a textured surface, no matter how much you smooth it, some people prefer to use gypsum plaster as a topcoat over cement plaster, creating a smoother surface.

Damp plaster does dry out, although the drying time depends on several factors, including the type of plaster, the surrounding temperature, moisture content, and the extent of the dampness. Sometimes, it can take weeks or months for wall plaster to dry naturally.

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.

In some minor cases, you can DIY drywall repair with minimal time and money spent. This method is best when you have a hole made by a singular problem, such as accidental furniture moving, and not a continuous problem, like a rodent infestation. 

Knowing what product to use is crucial. For example, small holes only need spackle, whereas large holes might need a new piece of drywall. You can flex your DIY abilities on this project, but if you’d like a second opinion or have a more significant problem, it’s best to call in a drywall repair pro.
