"They removed the old fiberglass insulation and sprayed foam insulation on the underside of my roof.  They also sprayed the rim joists of my basement.  So far the house seems much less drafty.

"Comprehensive estimate, especially compared to another estimate that I got which was cheaper. I ended up getting our house insulated with MetroNY given how detailed and the time and effort spent on giving me the right estimate for the job. The insulation was professional and the manager, Billy, was super polite and took extra time to understand what was going on in between the walls and floors. We now have the added benefit that the noise from the train that runs through our back yard is muffled thanks to the insulation. We await the cold of the winter to see if it worked. Antoinette"

Drywall Insulation questions, answered by experts

Eco-friendly options reduce environmental impact and often improve indoor air quality.

You should not leave drywall outside, especially overnight or in a wet, humid climate. Exposure to rain and humidity can damage the drywall, weakening its structural integrity and making it susceptible to mold growth. If you must leave drywall outside during a project, be sure to cover it with a tarp or keep it inside a storage shed to protect it. Even drywall intended for exterior projects requires a protective moisture barrier. For best results, store any extra drywall in a dry area away from the elements.

A jigsaw is commonly used to cut holes in drywall. It offers versatility and precision, making it suitable for creating circular or irregular openings. When equipped with the right blade, a jigsaw can swiftly and cleanly cut through drywall, making it a good choice for DIY projects.

While you can put new drywall over old drywall, it’s not always the best option. In some cases, drywalling over drywall can make it harder to find wires and pipes behind your walls and conceal more serious problems with your walls. It can also make the room smaller. On the plus side, putting drywall over drywall can improve soundproofing and insulation. Plus, it’s often less expensive than tearing down and adding new drywall.

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).
