"This work was performed in Groveland, FL, 34736. Capstone Insulation was great. The VP came out, went through the attic, and described the work to be done. This included thermal imaging to find air transfer locations, air sealing between the attic and living spaces, installing baffles over the inside soffit vents, installing and air sealing recessed lighting covers (for fire safety), installing new insulation, and pre- and post-insulation air flow testing. The installation crew was very competent and friendly. They performed the initial air flow test and all the pre-insulation work on day 1. They came back the next day to install the insulation and perform the final air flow test. The VP provided me with a video of the Day 1 work and a video of the final outcome. All of this work was done at a price point that I thought was reasonable (about $2/sq. ft.)."

"Deli Brothers Insulation came to my home and did an absolutely marvelous job from start to finish. From the moment they arrived, their professionalism was clear—they were punctual, polite, and ready to get to work. Not only did they complete the insulation quickly and efficiently, but they also kept the work area spotless, which I really appreciated. Their team was extremely knowledgeable, answering all of my questions and explaining the process so I felt informed every step of the way. It’s rare to find a company that delivers both top-quality workmanship and outstanding customer service, but Deli Brothers Insulation truly exceeded my expectations. I would highly recommend them to anyone looking for reliable, clean, and expert insulation services."

"Dennis and his crew are awesome! I called Dennis because I had condensation coming from an electrical outlet in one bedroom. In addition, my pantry and closets would always feel humid and warmer than the rest of the house. He came out and diagnosed the problem in an honest, professional manner: it turns out the builder of my house never did the air sealing under the attic insulation, so he took care of that. I also had him do wall-injected insulation on the wall that is hit by the sun all day, as well as add more attic insulation for energy efficiency. Dennis is responsive, knowledgeable, and won't sell you stuff you don't need. I'll be recommending him to neighbors who have houses built by the same builder, and who probably have the same problem I did."

Drywall Insulation FAQs, answered by experts

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.

There are several things you should not do when installing drywall. Common mistakes include: adding too many screws, over-sanding, not adding backing support, and installing drywall unevenly. You also should avoid screwing into the same place twice, installing Sheetrock with tapered edges on the outside, and making too many joints.

It doesn’t matter which way you lay drywall, and you can choose to install it horizontally or vertically depending on the size of the wall and how tall the ceiling is. It’s easier to lay drywall sheets vertically if you have a taller ceiling, but laying sheets horizontally makes it easier to apply joint compound.

Your walls are likely cracking due to fluctuations in the temperature outside. Drywall tends to expand and contract when temperatures and humidity levels change, and this repeated movement can lead to cracks in your walls, particularly around door frames. If you have multiple diagonal cracks, you may want to have your foundation inspected, as cracks can also be a sign of a bigger issue.

Yes, cabinets are installed over drywall. The drywall must be in good condition, and you must ensure that the wall can handle the weight of the cabinets. Secure the cabinets to studs and use proper anchoring devices, like toggle bolts.
