"⭐⭐⭐⭐⭐ Excellent Work by Sebastian – Jersey State Insulations We recently had insulation work completed by Jersey State Insulations, and Sebastian and his team did an outstanding job. From the beginning, Sebastian was professional, knowledgeable, and very easy to work with. He took the time to explain the process, recommended the right insulation for our space, and made sure everything was properly sealed and installed. The workmanship was clean, efficient, and done with great attention to detail. No shortcuts — just solid, quality work. Sebastian was punctual, respectful of our home, and left the area clean after the job was finished. We’ve already noticed an improvement in comfort. I highly recommend Sebastian and Jersey State Insulations to anyone looking for reliable and professional insulation services."

"The job was very well done. Gustavo and his crew were EXCELLENT. Dealing with the project Manager Taylor was EXCELLENT. One of a kind company. A unique feature that was used for installation was the inclusion of BOTH Sanford insulation and housewrap. I have not had another contractor offer me both of those. It’s always either one or the other. Home Genius is backed by the better business bureau and is a James Hardie certified installer for those looking for one."

"We had been living in our house for 5 years and although the kitchen was a new addition, every winter my wife & I had noticed how noticeably the temperature differentiated especially after the winter of 2014/15.  And because it was a dirt floor with some wood and old construction debris strewn about.  I was not so keen on staying down there.  In doing my own investigation there was some piping and insulation under floor.
So when investigating estimates we called a number of "green" companies.  Out of the three companies that came, only Frank Petrullo with Eco Green Solutions, noticed the mold and a water leak coming from fridge line.  He took the time to show me where the water was coming, how mold had proliferated on the wood floor joists and beams.  The dirt floor was somewhat moist and light was visible from outside along foundation rim contributing to the mold and moisture in crawl space.  He explained each of our options and detailed the steps in sections of each estimate.
We opted to have a plumber fix the water leak, then franks crew came in, cleaned up the mold, then layed down the crawl space membrane, finally insulating floor & rim joist.  All in under two days.  The crew showed up on time, left the open sections of the house clean, and we immediately noticed a difference in kitchen and rest of house.  Walking around bare foot in kitchen is more comfortable, the kitchen is less noisy, and house humidity is maintained.

Drywall Insulation questions, answered by experts

You can drywall an unheated garage because the material handles cold temperatures perfectly well. There are no risks or downsides to installing drywall in a garage that is not heated, and the material stands up to moisture and other elements quite well. Drywall will protect your unheated garage's electric wires and cables and add fire protection. However, for effective bonding, you should install drywall at a temperature of 55 degrees Fahrenheit or higher.

The best tool for skim coating drywall is a skim coating blade, which can smooth out joint compound in wide stretches. While you could use a smaller drywall knife for skim coating, the smaller size means it’ll take longer to smooth out each section. Instead, consider investing in a skim coating blade for the quickest application.

You can technically just paint over hairline cracks in plaster since these cracks are often harmless, but this will mostly be a waste of paint. Paint will only hide the hairline crack for a few months before it shows up again. The best solution is to repair the crack with flexible filler or joint compound before repainting.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.
