"Mike and his assistant were very professional. They worked until eight at night to complete the job, (excellent work ethics ) both were very courteous and pleasant and a pleasure to have working at my home. The insulation in my pole barn turned out perfect, and I couldnâ t be happier. I will use them again for future projects. Rob W"

"I'm very satisfied with the quality of work this company does and the price was very fair. Aaron, the owner, was easy to talk to and after a short discussion, he knew exactly what I wanted. Mike and Dan did the insulation and even replaced a few floor boards at a nominal cost. They politely answered all my questions and you could tell they enjoy their work. If you want a professional job done at a very reasonable price, I would definitely give G.E.G. Enterprises a call."

"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

Drywall Insulation FAQs, answered by experts

Yes, it matters which side of drywall you use. One side is smooth, and the other is rough. The smooth side should be facing outward, toward the room, while the rough side should be hidden and facing the studs and framing of the house. The smooth side will be easier to apply tape, joint compound, and, later, paint to.

While you can put new drywall over old drywall, it’s not always the best option. In some cases, drywalling over drywall can make it harder to find wires and pipes behind your walls and conceal more serious problems with your walls. It can also make the room smaller. On the plus side, putting drywall over drywall can improve soundproofing and insulation. Plus, it’s often less expensive than tearing down and adding new drywall.

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.

Whether to repair or replace water-damaged plaster depends on the scale of the damage. For small, limited areas, you can often perform a repair yourself. If you choose to paint over small patches, ensure the surface is completely dry and apply a coat of antifungal primer first to prevent mold growth. However, simply painting or plastering over the damage is only a temporary solution that doesn't address the core problem. For more extensive or long-term damage, the plaster may be compromised, and there is a risk of mold. In these cases, it is recommended to remove the damaged section of plasterboard and replace it. You may consider hiring a professional for the repair, and it's worth noting that water damage is often covered by home insurance.

You should not leave drywall outside, especially overnight or in a wet, humid climate. Exposure to rain and humidity can damage the drywall, weakening its structural integrity and making it susceptible to mold growth. If you must leave drywall outside during a project, be sure to cover it with a tarp or keep it inside a storage shed to protect it. Even drywall intended for exterior projects requires a protective moisture barrier. For best results, store any extra drywall in a dry area away from the elements.
