"Fantastic experience. Jeremy was awesome. Very honest and trustworthy! We received several quotes for attic insulation prior to selecting Energy Allies. Cannot say enough about customer relations. Jeremy and his brother were prompt, on time, and very competent in what they do. While trying not to bash the other companies that gave us quotes, all I will say is that their quotes and knowledge based compared to Energy Allies were, at best, suspect. As far as I am concerned Energy Allies (Jeremy & his brother) deserve 10 Stars!!"

"The team was very professional and world class! They went over and above everything I could've ask for. I noticed the difference right away. My home was built in 1910. It was much quieter and I never realized just how drafty my home was. Thank you all for your hard work!!"

Drywall Insulation FAQs, answered by experts

Cracks, water damage, and holes from fixtures or impact.

A common cause of separation between a wall and the ceiling is truss lift—this can happen to the ceiling of rooms directly under the attic when the seasons change and wood building materials dry out, shrink, and shift. Roof trusses often dry out at different speeds, and if the bottom pieces dry out faster than the top pieces, they can shrink and pull the attached drywall away from ceilings and walls, causing cracks. Fortunately, truss lift is only a cosmetic problem, not a structural problem, and you can fix it by separating the ceiling drywall from the roof trusses, and patching the cracks.

Although they have similar applications, spackle and joint compound are not the same. Their primary differences lie in their composition, consistency, and ideal use cases.

Spackle is composed of gypsum and binding agents, making it thicker than joint compound. It dries quickly and is easy to sand, which makes it ideal for small wall repair projects like filling nail holes or patching minor damage.

Joint compound, also known as drywall mud, consists of limestone and gypsum. It is primarily used for large-scale projects, such as taping and finishing the seams on newly installed drywall. It tends to shrink more than spackle and can be more difficult to spread.

While both products can be used to fill small depressions and cracks, spackle cannot replace joint compound for taping and mudding new drywall. Conversely, you can often use joint compound for small patching jobs typically done with spackle.

The best tool for skim coating drywall is a skim coating blade, which can smooth out joint compound in wide stretches. While you could use a smaller drywall knife for skim coating, the smaller size means it’ll take longer to smooth out each section. Instead, consider investing in a skim coating blade for the quickest application.

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.
