"After contacting Jace, he came and did an assessment. He sat down and gave us a very fair bid on adding blown in insulation to our attic. We accepted the bid and he and his partner were back in a week’s time. They were very timely on arriving and were finished in their estimated time. They cleaned up the area very good. I highly recommend this company for any insulation needs."

"They were very helpful on advising on specifications. In general, I found roofers specifying roof replacement the cheapest way possible rather than what is most cost effective long-term. Once, I got multiple contractors matching on specs, GF was clearly cost competitive, particularly given no subcontractor usage. Actual install was smooth except for two things. It took more time than they budgeted for, but they handled that well and didn't try to ask for extra payment. Second, they discovered that the backing of the house's original aluminum siding was rotten when they were installing new flashing. Understandably, they didn't want to put it back up as is (which I can appreciate). Thankfully, they were able to provide a cost effective answer regarding new siding, as I didn't want to have to big that out with everything already torn up."

Drywall Insulation FAQs, answered by experts

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.

There are some instances when you can use extra drywall in your garden. Ideally, unused scraps of new drywall are best for amending soil without the concern of additional chemicals or mold. However, drywall with paint, mold, or potential asbestos requires specialized disposal by a professional and should be kept out of your garden.

You can skim coat plaster, but it’s better to repair the plaster itself. A skim coat is a thin coat of drywall joint compound spread over the surface of a wall. The result is a flat finish that looks pleasing, but part of the appeal of plaster is its imperfections and aesthetic. Skim coating is best when limited to drywall applications.

Plaster that sags or bulges, shows extensive deep cracks, or is crumbling from water damage or simply time may need replacement. Plaster walls can look a little “worn” for a long time before they need replacing. The only real way to know if it needs a replacement is to hire a professional to assess the condition of the plaster.

Knowing what causes drywall damage can help stop it before it starts. Here are some of the most common causes of drywall damage: 

  • Water damage from roof leaks or leaky pipes. 

  • Small holes caused by doorknobs, minor accidents, and rodent infestations. 

  • Wall dents stemming from moving furniture and minor accidents. 

  • Wall cracks that form from a settling foundation or seismic activity. 

  • Nail pops from nails and screws in the walls. 

  • Large holes that are caused by accidents with heavy objects, children and pets, or sporting equipment.
