"⭐⭐⭐⭐⭐ 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."

"We are extremely satisfied with the whole process of our house being insulated. First we had the walls done, and then a couple weeks later we had our attic insulated. The crew were so nice, friendly, and knowledgeable. We are very satisfied with everything. Thank you, everyone."

"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."

"Although I am pleased with the company & service provided overall (spray foam insulation), I was disappointed to find 17 bags of old insulation had been left in my yard! I was told it would be would hauled away when the job was complete. When I contacted the company, Dave advised it would be picked up...I'm still waiting ?"

"Travis was,very reasonable, punctual and did the job very efficiently, leaving no mess behind. My family room wood floor is now insulated below in the crawl space, eliminating the previously cold floor we had before the insulation. The insulation also protects the wood floor by adding a vapor barrier. We are very pleased and would recommend Travis and Enviro Foam Tek."

Drywall Insulation questions, answered by experts

A utility knife is sharp enough to score the drywall and it may work in a pinch for outlet box holes. However, one of the best tools for drywall when you need to make exact cuts for an outlet box quickly is a drywall saw. This handheld tool has a longer blade than a utility knife, so it penetrates the thickness of the drywall easily. The design of its handle and the teeth in its blade make it easier to control while cutting quicker than you can with a utility knife.

Vinegar and bleach are effective options for removing mold from drywall. Vinegar is a better choice if you have a smaller mold issue while bleach is best if you have a larger mold problem. If the area you're cleaning has limited ventilation, using vinegar would be a better option. In that case, you could mix vinegar with baking soda to remove more stubborn mold growth.

Deciding whether to repair or replace drywall can be tricky, but your top considerations should be the extent of the damage and what caused the damage. For instance, if you need to repair a small hole caused by a doorknob that hit the wall, you can safely patch it without a second thought. However, if you have significant drywall damage caused by water damage, it’s best to thoroughly remove the drywall to inspect and repair the pipes behind it before replacing it.

Yes, applying a texture can hide minor imperfections and irregularities in drywall, but it will not cover significant damage like nail marks or screw holes. The best texture depends on the size of the flaws. For minor imperfections, popular choices like orange peel, sand, or popcorn texture are effective. For larger imperfections, you may need a more prominent style, such as a knockdown or trowel finish, to conceal them effectively.

It is possible to apply plaster on the interior or exterior of your home, but we don’t recommend it. Plaster is easy to apply in theory, but in reality, it can be a challenging material to work with, and it’s difficult to get the finished product to look clean, even, and smooth. Many DIYers end up calling in a professional afterward to touch up the area or even redo it entirely because of mistakes they made in the process. Hiring a plaster pro will cost more, but it’s usually the best option to achieve high-quality results.
