"I'm extremely impressed with Luis and Icon Insulation. After moving into a 115 year old house about 5 months ago, and having a lot of contractors doing various jobs, Luis was a breath of fresh air! I had him Insulate my attic, and then I had him back again to insulate under our floor. I would highly recommend Icon Insulation to anyone I know. They are very responsive and answered all my questions before our appointment, punctual, professional, and have a great work ethic. (Something hard to find these days.) Thank you for your great work!"

"Fantastically well! I would highly recommend America One Insulation to anyone requiring insulation removal and installation. Their team worked non-stop to remove all the old insulation in our attic; putting in a 12 hour day. David, the owner of America One Insulation, followed up prior to the team arriving (a father and son) during the removal process, as well as that evening. One could not ask for a more professional company to do business with."

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

"Excellent. The rep showed up on time and did a very thorough job, complete with photos and a write-up of all the affected areas. He also gave a quote to perform both the exclusion work and to clean & replace the soiled insulation. I will be calling them to do both jobs shortly."

Drywall Insulation FAQs, answered by experts

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

The two most common drywall thicknesses for ceilings are 1/2-inch and 5/8-inch. For most standard residential applications, 1/2-inch drywall is sufficient and widely used. It provides adequate support and is lighter and easier to handle during installation compared to thicker sheets. However, 5/8-inch drywall is often used for specific cases where additional benefits are needed. It is heavier but provides superior sound dampening and fire resistance. You should consider using 5/8-inch drywall for ceilings in commercial buildings, between a garage and a living space, or above a finished basement to meet building codes or for enhanced soundproofing.

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.

It’s always better to follow proven drywall repair tips and fix the seams that look bad. However, if you simply want to make them less noticeable until you have time to fix them, you can use paint. A darker color of paint makes bad drywall tape seams less noticeable than light-colored paint. Matte paint hides bad seams better than glossy paint does, too.

Whether you can reuse a drywall anchor depends on its type, material, and how it is removed. Plastic anchors, such as expansion or self-drilling types, are generally considered single-use because they are designed to expand and are likely to break or become deformed upon removal. Metal anchors, like toggle bolts, are more durable and can often be reused if they are not damaged during extraction. However, with toggle bolts, the toggle mechanism can fall inside the wall when the bolt is removed, making it difficult to retrieve. If an anchor is damaged or must be cut for removal, it cannot be reused regardless of its material.
