"Courteous, diligent, professional and fair priced. Without reservation I would highly recommend Q-insulation. They installed rock wool insulation in all the ceilings and on the vertical attic walls in our historic brick victorian. They were prompt, on time and treated my home like it was their own. Thank you Valeria and the crew."

Drywall Insulation questions, answered by experts

If you suspect black mold is inside your walls, do not punch a hole in the drywall yourself to look. Call a mold inspection expert to help you. Some signs of a potential black mold infestation inside the wall include an unexplained musty, damp smell. Some people liken it to rotting vegetables. You may smell it most strongly through a wall outlet. If you and your family are experiencing constant coughing or symptoms that feel like an unexplained allergy, it could indicate black mold behind a wall.

It’s highly recommended to use studs for a TV mount. The last thing you want is to be watching your favorite show when the TV falls off the wall. Studs are much stronger than drywall and quite a bit stronger than drywall anchors but, if you can’t find the studs or there simply aren’t any where you need them, you can use drywall anchors. It’s extremely important to make sure the anchors are rated for the load of the TV. We recommend using anchors that are rated far beyond the weight of whatever you’re hanging. Our suggestion is metal drywall toggle anchors. 

While not always necessary, you can glue a drywall ceiling in addition to using screws or nails. Drywall is typically secured to ceiling joists with fasteners, which is often sufficient. However, adding construction adhesive can offer benefits like preventing sagging, bridging gaps, and reducing air leaks for better energy efficiency. It may also be used for specific acoustic or insulation needs. On the other hand, many professionals advise against it because properly placed screws make the drywall structural, glue doesn't add strength, and it makes future repairs or replacements significantly more difficult. Ultimately, it's best to follow local building codes and project-specific requirements to decide if adhesive is right for your ceiling.

There are several benefits to wet-sanding drywall, but the main perk is that it produces far less dust than dry-sanding. As a result, wet-sanding poses fewer health risks and makes less of a mess in your home. Plus, damp sponges are less abrasive than sandpaper, so there’s a smaller chance of scratching or damaging the drywall paper. Wet-sanding also creates a smoother finish than dry-sanding.

In most cases, no, you won’t need a permit to replace drywall. If you’re changing the floorplan of your home by adding or removing walls during the drywall project, then you might need a permit, but replacement or repairs usually doesn’t require a permit. Your drywall professional should be able to confirm whether or not a permit is required for your project. If it is, it’s likely to add between $50 and $150 to your total cost. Keep in mind that you will need permits if you plan to install new electrical wiring or plumbing lines behind your new drywall.
