"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 FAQs, answered by experts

Plastering lasts for around 15 to 20 years without needing repairs or maintenance in most cases, and with proper upkeep, plastering can last a lifetime—sometimes more than 100 years. Plaster repair costs between $1 and $3 per square foot, and you may need these services once every 15 to 20 years or so unless you have a harsh climate where humidity changes are a constant issue. You can also opt to skim-coat plaster for between $0.90 and $1.30 per square foot, which may serve you better in the long run.

According to the EPA, mold grows within 24 to 48 hours if left untreated after a water leak. So unless you notice the leak and stop it right away, you only have a day or so before mold is a real concern. If you don’t notice the leak, it can take about three weeks for the mold spores to become visible. That means you’ve likely had an active mold infection for a few weeks by the time you notice discoloration.

You can paint over drywall mud about 24 hours after application, but the exact timing depends on factors like humidity, temperature, and the thickness of the mud. For the best results, ensure the mud is completely dry to the touch and has changed from a darker gray to a lighter, chalky white. Don’t forget to sand and prime the drywall surface before you paint to create a smooth, even finish.

The age of your home can clue you in to whether you have plaster or drywall ceilings. Homes built after the ‘70s are more likely to have drywall ceilings and walls, while older homes have plaster. You can also do the pushpin test: A pushpin will go into drywall, whereas it’s much harder to push one into a plaster wall. If you’re still unsure, ask a drywall professional to let you know which type of ceilings and walls you have.

Look for flaking paint or air bubbles that burst and then flake away. Paint will begin to flake after being exposed to minimal moisture or water, so it’s a good indicator of any water damage. If you notice your paint starting to flake, feel the plaster underneath to see if it is soft or damp.
