"They showed up exactly when they said they would. They were efficient, neat and made sure to send me pictures in the various stages of execution. And they cleaned up better than when they found the area. I would highly recommend them. I wish he did more than insulation because he would be my go-to guy for all house related needs."

Drywall Insulation FAQs, answered by experts

Plaster is a pretty tough surface, but it can still sustain damage from things like bumping against it, water issues, dampness, extreme humidity changes, and plain old age. Most plaster walls last hundreds of years and will only be taken down to the base layer when major repairs are required. Being cautious around the wall, not placing furniture against it, and ensuring stable humidity are all great ways to reduce possible damage.

If you already have plaster walls and ceilings, adding new plaster costs $2 to $10 per square foot. For an average-sized room, that would come out to $1,200 to $10,000. However, the cost to replace plaster with drywall is higher—running between $720 and $1,250 for a 10-by-8-foot wall or ceiling (not including drywall finishing).

Yes, you can hammer a nail into a wall stud. But before you do, it’s important to confirm that you’re actually nailing into a stud—and not wiring, pipes, or ductwork. To check, find a few more studs in the wall, then measure to make sure they’re either 16 or 24 inches apart.

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.

On average, drywall installation costs around $2,000, with a typical range of $400 to $6,000, including materials and labor. The final price depends on several factors. The most significant is the size of the area, as many contractors charge per square foot. Other cost factors include the complexity of the job (e.g., cutting around multiple windows and doors, corners, or curved walls), accessibility, location, the thickness of the drywall, the height of the room, and the desired level of finish. The level of finish can range from simply hanging the drywall to taping and mudding the seams and painting the walls.
