"I had an excellent experience with this insulation company and their crew. From start to finish, they were professional, timely, and extremely organized. 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."

"Rep. checked entire system. He found several wires not connected properly and fixed this. He also made recommendations regarding the attachment of the panels to the rood that would provide more stability and leakproofing. The representative appeared to know what he was doing - much better than others, including the representative who was engaged by the roofer (who replaced our rood due to hail damage) to disconnect/connect the panels."

Drywall Insulation questions, answered by experts

A utility knife is sharp enough to score the drywall and it may work in a pinch for outlet box holes. However, one of the best tools for drywall when you need to make exact cuts for an outlet box quickly is a drywall saw. This handheld tool has a longer blade than a utility knife, so it penetrates the thickness of the drywall easily. The design of its handle and the teeth in its blade make it easier to control while cutting quicker than you can with a utility knife.

Very little. One inch of water can stain walls, warp wood, and create a perfect environment for mold growth. One to two inches of water can do significant damage to drywall, insulation, and electrical systems. Anything over that is considered an extensive flood, often resulting in severe structural damage.

While it’s most common to sand plaster dry, it is possible to wet-sand plaster, too. Doing so can reduce the amount of plaster dust released into the air and make it easier to work in smaller, more delicate areas (such as around wall trim). However, some people find that wet sanding leads to more imperfections, which is why larger walls are more often dry sanded to ensure an even finish.

You can technically just paint over hairline cracks in plaster since these cracks are often harmless, but this will mostly be a waste of paint. Paint will only hide the hairline crack for a few months before it shows up again. The best solution is to repair the crack with flexible filler or joint compound before repainting.

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.
