"⭐⭐⭐⭐⭐ 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

If your home was built before the 1940s and was not remodeled in the past 50 or so years, you probably have plaster walls. Aside from assuming, there are some practical ways to tell if you have plaster walls, including the following: If you knock on the wall and it feels solid, not hollow, if you can’t insert a thumbtack easily, if there are cracks that look like spiderwebs, or if your home has curved, arched, or swirled walls, doorways, or window openings.

If you have an unfinished basement or attic, you could examine the backs of any finished walls to check, too.

Plaster that sags or bulges, shows extensive deep cracks, or is crumbling from water damage or simply time may need replacement. Plaster walls can look a little “worn” for a long time before they need replacing. The only real way to know if it needs a replacement is to hire a professional to assess the condition of the plaster.

If your home’s foundation shifts slightly over time, any seams in the drywall represent the weakest point in the wall, leading to cracks. If your home has significant changes in temperature and humidity, this can cause the drywall to swell and contract slightly, causing a crack at the weak point of the seam. If your drywall installer did a poor job securing the panels to the wall studs, this could cause a weak layout and cracks in the seams.

You can put certain types of plaster over other types, but doing so isn't always the best idea. For example, putting a coat of gypsum over lime plaster is possible, but doing so will limit the lime plaster's breathability and potentially affect its performance.

Since cement plaster tends to leave a textured surface, no matter how much you smooth it, some people prefer to use gypsum plaster as a topcoat over cement plaster, creating a smoother surface.

Drywall tape is made of paper, while drywall mesh is made of fiberglass or metal. Drywall mesh patches are suitable for repairing small holes in drywall, while paper drywall tape holds a crease better for corners. You need joint compound to adhere drywall tape to the wall, while mesh patches may be self-adhesive.
