"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.

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

You can paint over plaster, but repair any damage to the plaster first, or the paint will crack and bubble. You should also prepare the surface of the plaster to accept paint, which gives your paint job the best chance of looking good and lasting a long time. Before applying the color you want, apply a coat or two of primer. Additionally, use latex paint, and choose a latex paint with a satin finish for areas with dampness, like bathrooms.

Drying alone can take 1 to 4 hours to dry to the touch per plaster layer, but some types of plaster take several hours longer to dry. However, this doesn’t mean the job is done because plaster doesn’t fully harden until it cures, which can take a few days to a couple of weeks. It may take even longer if you’re building a new, pretty thick plaster wall. Allow the plaster to cure before painting it.

There shouldn’t be any gaps between your walls and ceiling. These can be fixed with joint compound but that is only a fix, and it’s much better if your drywall fits correctly in the first place. Sometimes gaps can appear if your foundation shifts significantly but if this is the case, you have a much bigger problem than patching drywall.

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.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.
