"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."

"Contacted Master Attic via Angi and Alex, the technician came to evaluate our attic and crawl space (2 separate spaces in our house). We heard critter noises and our upstairs was hot in the summer. The insulation was original to the ~30 year old house, so we know it's about time to get it done. Alex checked both spaces and showed us photos of problem areas. We have an estimate and Alex explained the details of the work involved. The team came within the week (we lucked out to take the spot of a cancellation), and everything was done as expected. There was a lot of work to remove old insulations, vacuum all debris, sanitize the space, seal all air gaps, install baffles, rodent proof, and install new insulation. The work was completed in around 6 hours, the spaces are now clean and tidy - quite unbelievable given how they were before. We went for the heavier insulation which is reflected in the project cost."

Drywall Insulation FAQs, answered by experts

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.

Most drywall used for interior walls of homes is 1/2-inch thick. This size strikes a balance of being easy to handle and hang while being thick enough for the durability needed on interior wall applications.

Whether a drywall anchor can be reused depends on its material, type, and the method of removal. Plastic anchors, including expansion and self-drilling types, are generally designed for single use as they tend to break or deform upon removal. Metal anchors, such as toggle bolts, are more durable and may be reusable if they are not damaged during extraction. However, with toggle bolts, the toggle piece can fall into the wall cavity when the bolt is removed, making it difficult to retrieve. If an anchor is damaged during removal, for instance by having its head cut off, it cannot be reused regardless of the material.

Yes, professionals often repair minor wall openings made for insulation injection to restore the surface.

Deciding whether to repair or replace drywall can be tricky, but your top considerations should be the extent of the damage and what caused the damage. For instance, if you need to repair a small hole caused by a doorknob that hit the wall, you can safely patch it without a second thought. However, if you have significant drywall damage caused by water damage, it’s best to thoroughly remove the drywall to inspect and repair the pipes behind it before replacing it.
