"Working with Vortex was a great experience. The crew was totally professional and very experienced and did an excellent job spraying closed cell insulation in the new addition to our house. When they were done the job site was left totally spotless. Their prices are very reasonable/competitive. We are very pleased with the work they did and how easy it was to work with them. We will certainly use them again in the future."

"American Attic was everything they promised. Met with the owner , Sam, within a day to get a quote for removal of old insulation, rodent control and install of new insulation. He was professional and explained everything in detail of what was work was going to be done and how long it would take. We scheduled within a week at a reasonable price. His crew were neat, organized and finished on time! We were notified of some extra things that were found while they were on the job but were not pressured to have those things done. We recommend American Attic to friends or family and would definitely use them again."

"When Insulation Alliance came, they were very professional. They laid down plastic everywhere in the hallway and the bedroom. They cleaned out the whole attic. They took out the old insulation and put in the new Insulation which was R 44. They cleaned up everything and everything was clean when they left. They also sanitized the attic. You will not be disappointed that you hired."

Drywall Insulation FAQs, answered by experts

Whether it’s better to screw or glue drywall depends on your specific budget and project timeline. Professional drywall installers are more likely to use screws and fasteners than adhesives, but it takes longer. But if you are DIYing your drywall installation, glue is a perfectly fine choice if you’re willing to pay extra for adhesive.

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.

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.

Yes, as drywall mud is going to have some uneven spots and bumps after application. Such imperfections are going to be visible after everything dries and even after you paint the wall, so you want to remove them. Learning how to sand drywall, taking your time, and following drywall sanding tips can help you have the best results.

Yes, small, superficial cracks are normal as homes settle. Older homes have a higher chance of showing signs of settling through hairline cracks from temperature changes, moisture changes, and soil shifting. However, larger cracks, or discolored cracks from water damage, may signify a bigger problem that requires reparations and preventative measures.
