"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"

"G.E.G. did a great job installing blow in insulaltion in my attic. They were quick and prepared. My only wish is they would have been able to pull up more of the unused attic flooring and gotten more insulation under it, though they were able to increase insulation in other areas."

"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."

"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

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.

You can take a few steps to save money on drywall installation, even when hiring a professional to do the bulk of the work for you. These ideas include the following:

  • Buy the drywall and other materials yourself to avoid product markup and delivery fees

  • Ask about discounts if you use the same company to tape, spackle, and paint

  • Hire drywall professionals in the winter when demand is the lowest

  • DIY as many parts of the project as possible, like replacing insulation and painting

Whether Venetian plaster increases your home's value often depends on the buyer's preference. As a purely aesthetic upgrade, it doesn't add structural value in the same way a kitchen or bathroom remodel might. However, its beautiful and attractive appearance can make a home more appealing to potential buyers, possibly leading to more interest, higher offers, and increased competition when you sell.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

Plastering and skimming are two different techniques for finishing walls. Plastering involves applying a thick layer of a plaster mixture—typically containing gypsum, lime, cement, sand, and water—to create a new surface. This process often requires multiple coats and is used for repairing significant damage or creating decorative textures. Skimming, on the other hand, is a technique that involves applying a thin layer of drywall compound or joint compound over an existing surface to smooth it out, covering minor imperfections, small cracks, or uneven textures for a polished look. Plastering is generally more costly and labor-intensive than skimming. Although some people use the terms interchangeably, they refer to different processes and materials.
