Crawlspace Encapsulation in New Jersey

We provide professional crawlspace encapsulation to seal out moisture, improve air quality, and enhance energy efficiency for your New Jersey home.

Overview of Crawlspace Encapsulation

Crawlspace encapsulation from A1 Everlast involves sealing your home’s lower levels with a heavy-duty vapor barrier. This comprehensive process prevents moisture from rising through the soil, effectively turning a damp, dark space into a clean, dry, and conditioned environment in NJ.
Our New Jersey technicians also seal vents and insulate walls to stop humid air from entering. This system works in tandem with dehumidifiers to maintain a consistent environment, protecting your home’s wooden structure and improving the overall health of your local living space.

Importance of Crawlspace Encapsulation for New Jersey Homes

In New Jersey, humid crawlspaces are breeding grounds for mold, rot, and wood-destroying pests. These issues can compromise your home’s structural integrity and release harmful allergens into the air your family breathes, leading to poor indoor air quality.
Encapsulation by A1 Everlast provides a permanent solution to these common NJ problems. By controlling moisture levels, you protect your flooring from warping and reduce energy bills, as your HVAC system won’t have to work as hard to maintain a comfortable temperature.

Back in 2020 A1 Everlast demo’d my dad’s front stairs and rebuilt a beautiful stone porch & set of stairs in its place. They were a great bunch of guys knowledgeable, kind, quick & skilled. Unfortunately due to the weather & a lot of rain the stairs sustained a little damage. Since my dad passed away in 2024 I reached out to Tim to inquire about the 10yr warranty they had given for their workmanship. I can’t say enough about Tim. He was so apologetic & went to work right away to resolve the problems we were encountering. All while he himself was dealing w/ a private health issue within his family. Thank you Tim for everything I highly recommend A1 Everlast for all concrete and stair/porch work! They are #1

We had a great experience with A1 Everlast. They rebuilt our fireplace box, installed a new liner, and added a new crown, and everything was done with excellent attention to detail. John was especially attentive throughout the process and made everything feel simple and stress-free.

The team was very professional, respectful, and easy to work with. We also really appreciated how quickly they were able to get started—coming out the very next day after inspecting our chimney.

Overall, we’re extremely happy with the quality of the work and would highly recommend A1 Everlast to anyone needing chimney repairs or restoration!

What a great experience! We called for an estimate on waterproofing the basement. Bob was timely, professional, and friendly. We were scheduled at our convenience - no excessive waiting and not rushed. Altogether the job was completed efficiently and they cleaned up after themselves. Thanks again!

If you are looking for a contracting company that actually delivers on its promises, look no further than A1 Everlast. From start to finish, my experience was nothing short of exceptional, and that is largely thanks to Anthony.
In an industry where it’s hard to find people you can trust, Anthony is a breath of fresh air. His professionalism was evident from our very first meeting; he arrived on time, respected my property, and communicated clearly throughout the entire process. What impressed me most was his depth of knowledge. He didn't just give me a quote; he took the time to explain the technical aspects of the job, offered intelligent solutions for my specific needs, and ensured I understood exactly what was being done and why.
Perhaps most importantly, Anthony operates with a level of honesty that is rare to find. A number of contractors I've come across in my years of being a real estate investor have attempted to fabricate issues just to secure a job to perform. It was intuitively clear to me that after speaking with Anthony this was not the case. His assessment was genuine and tailored to my specific needs. Words cannot explain how pleased and satsified I am in dealing with A1. To many more, thanks Everlast and just as importantly thank you Anthony!

I had a great experience with this company. Tim came to my house to provide a roofing estimate and explained everything clearly and honestly. He was professional, knowledgeable, and took the time to answer all my questions. The repair work was done carefully and efficiently, and the pricing was fair. I really appreciate his reliability and attention to detail. I would definitely recommend Tim to anyone needing roofing estimates or repairs.

We had Bob come and take a look at our chimney and roof as we are first time home buyers and wanted to ensure the chimney was in working order. we also noticed with our roof a small soft spot on our ceiling that he was able to find out that there was a small portion on our roof that needed some work to stop the issue. He was personable, professional, and ensured that all our questions were answered/ satisfied. 10/10 would recommend giving Bob a call!

Very responsive, professional, and punctual team. I called Anthony in the morning, he was at the house that same afternoon, and had workers on site by 9 a.m. the following day to repair a gas/carbon monoxide leak. He estimated the job would be done by 3 p.m., and it was completed by 1:30. Highly recommend them — 100%.

Chimney repair due to water damage and age. They also installed a new damper. Timmy, Carlos, and Victor were all excellent. They did the job with excellence and they did it quickly. From the time I called to the time they signed the contract was quick, the price was reasonable, and they were just a pleasure to work with. Once we signed the contract, they arrived to do the job as scheduled only days later. They were on time. They were polite and courteous.They did a great job and cleaned up very neatly afterwards. No hassles.
