Encapsulating a crawl space in Freehold means sealing it off from the ground and the outside air with a heavy vapor barrier, not just laying plastic over the dirt. The clay-heavy ground under most of Monmouth County drains slowly and stays wet for long stretches, and township ranches and colonials built with a crawl space instead of a basement sit directly on top of it, so the barrier has to climb the walls and wrap every pier, not just cover the floor.
Before the barrier goes down, we check what is already in the crawl space. Old insulation that has absorbed moisture or gone moldy comes out, foundation vents get sealed instead of left open to outside humidity, and any debris or rodent activity gets cleared so the liner sits against a clean surface. Skipping that step is why some encapsulation jobs fail early, the barrier ends up sealing a problem in rather than keeping one out.
There is no charge for the estimate, and what you get in writing covers exactly what we find, whether that is a straightforward install over a clean crawl space or a job that needs cleanup, insulation replacement and rim joist sealing first. A Freehold crawl space under a newer colonial and one under an older borough foundation rarely need the exact same scope, which is what the inspection sorts out.
The insulation, cleanup and exclusion work that usually goes alongside a Freehold vapor barrier install, starting from the same free inspection.
Four reasons a Freehold, NJ crawl space ends up on our encapsulation list.
Monmouth County's clay-heavy ground stays saturated through much of the year and swells and shrinks across freeze-thaw winters, and an unsealed crawl space under a Freehold house sits right against that moisture with nothing between the dirt and the framing above it.
Township ranches and colonials built through the postwar decades mostly rest on crawl spaces, while some older borough properties have masonry foundations that trap the same dampness against the walls instead of the floor. Either way, the fix is the same barrier, applied where the moisture actually sits.
Older crawl space designs relied on foundation vents to keep air moving, which sounds reasonable until a Monmouth County winter pushes cold, damp air straight through them and onto the framing above. Sealing those vents instead of relying on them is a big part of what makes encapsulation work.
A damp, unsealed crawl space is an easier place for mice and other small animals to get comfortable than a dry, sealed one, and Freehold's foundation vents and skirting gaps give them a way to reach it. Encapsulation closes off both the moisture and most of the access at once.
Dry ground. Sealed walls. Cleaner air upstairs. Lower bills.

Master Attic did a phenomenal job with our attic insulation and duct replacement. We had a loss from smoke damage from a neighboring fire and we were met with compassion and excellent customer service from Danny Jones and Jorge Diaz. We chose them for their quality of work, expertise and fair pricing and they got the job done promptly. Thank you for the excellent work and we will be recommending you highly!
We just had our attic insulation replaced, and the entire experience was pleasant from start to finish. Robert is knowledgeable, honest and easy to work with at the initial estimate period. Roberta and his crew did a great job replacing the attic insulation for our house. They were very professional, efficient and respectful. They did everything that needed to be done and left the space clean and in excellent condition. I am very happy that I chose Master Attic and would highly recommend them.
Dan Jones and the Ronald crew did a great job from start to finish! I had original insulation in my attic with no electricity, not an easy job. Our upstairs was very hot in the summer and cold in winter. With having central air, we still needed AC units and space heaters to manage. Dan set up a great plan to eliminate that. He and his crew were able to come and finish the job shortly after we first met. They were quick, clean and managed to crawl into small spaces to remove old insulation and install fresh insulation. We have already noticed a major difference! Highly recommended!!
We hired Master Attic to clean out debris, mice, old insulation, and replace with new insulation in both our attic spaces. Roberto and his crew did a phenomenal job. They were extremely professional, polite, and did a fantastic job. They invited my husband to see the attic after each step, and took pictures on their phone to show me since I could not get up in the attic. They took the time to protect the space with plastic sheeting before the job up in the attic, and then cleaned up everything perfectly afterwards. I highly recommend them!
Great job by the team. Cleaned out the entire attic and replaced all the old insulation with new fresh insulation. Made a huge difference. Alex was great to work with and was very professional. Would highly recommend.
Awesome experience from start to finish. Rob provided a great assessment and capabilities overview, arrived on time and was very generous and thorough in explaining the work. I signed on the spot. A crew of six arrived (again, on time) and completely transformed our attic space - thoroughly cleaned out the old insulation (looked spotless afterwards), sanitized the space, sealed it/rodent proofed it, added baffles and of course, replaced the insulation and added more in areas that needed it. Completed the whole job in half a day and we are delighted with the result. Thank you, Master Attic team, for a job very well done! Highest recommendation.
What a great experience I had with this company and its employees. It started with initially interacting with Joe who came out for the estimate. He was funny because he came down from my attic and said "have you seen up there". I laughed because I had and I knew it was bad. He was no pressure and no nonsense. Gave me an estimate and said if I wanted we could have the work done next day. I wasn't ready for that but after some schedule juggling I told him we could be ready. Joe had his guys out next morning with the best part being Jorge calling me to advise he was about thirty minutes out. I appreciate when I am given a heads up as to ETA. Three of them arrived Jorge set out plastic and covered exposed furniture. Jorge, Angel and Gonzalo were all polite and worked hard to complete the task. They worked efficiently and were done quickly. Jorge made sure he included me in each step of the process and when I saw the finished product I was amazed. I can actually use my attic for storage if I choose to do so. I did not realize when they were here that they also do work on crawlspace areas. I will be calling them back to see what they can do for my crawlspace which easily rivals the diasaster called my attic. I recommend at least giving this company and its employees an opportunity to help you.
Great company to work with. From beginning to end, Dan came out, spent plenty of time with me going over everything that needed to be done, and the process of everything that needed to be updated it both attics. His professionalism was top notch, answered all my question and concerns. When it came time for George and his six-man crew to do the work their quality of workmanship was well above average, they were here the whole day, and I don't think they even had a lunch break (hopefully I don't get him in trouble). They all worked and everyone knew what their job was, they removed all the insulation, cleaned, spray foamed all holes and top plates, re-insulated both attics and cleaned up like they weren't even here. Will definitely use them again.
Master Attic remediated a bat issue for us back in October and I can’t say enough about what a wonderful job they did. The work was guaranteed and they encouraged us to call if we say any further evidence of bats. Well, there were a few droppings in the attic and they quickly responded to our concerns. Jose’s crew came out on a SUNDAY, inspected the attic, and sealed up several spots that could be entry points. They were professional, efficient, and kind. I would highly recommend them. You will not be disappointed.
A heavy vapor barrier gets fastened down over the dirt floor and run up every foundation wall, seams get taped, and vents and other openings are closed off so outside moisture and air stop reaching the space. Where the insulation underneath has failed or the crawl space needs cleaning first, that work happens before the barrier goes in, not around it.
Not necessarily. Batts that are still dry and have not been nested in can often stay put while the barrier goes in around them. Where the material has absorbed ground moisture or gone moldy, though, it comes out first, because sealing a barrier over wet material just traps the problem instead of solving it.
Freehold falls in JCP&L territory, and New Jersey has periodically run Clean Energy Program incentives touching moisture and insulation projects like this one. Ask what is currently active when we are out for the inspection, since the list is not identical from one year to the next.
It will not undo an active flood. What encapsulation handles is the slow, year-round dampness a sealed crawl space normally deals with. A storm that leaves standing water calls for pumping it out and letting the space dry completely on its own, and that part comes before any vapor barrier work starts. Once dry, the barrier takes over and keeps the clay-soil moisture from building back up.
We look at how wet the ground is, what shape any existing insulation is in, where the vents sit, whether the foundation has cracks, and whether rodents have been active, since Monmouth County's clay soil and the township's crawl space construction both play into what a given house needs. What gets recommended, and how much of it, depends entirely on that walk-through.
Two things drive the timeline most: how easy the space is to access, and how much old insulation or debris needs clearing out first. A clean, dry space with straightforward access moves faster than one that needs cleanup or removal ahead of the barrier. Your written estimate lays out the schedule for the specific job before any work begins.
Yes, across Monmouth County, including Marlboro, Manalapan, Millstone Township, Howell and Colts Neck, and Jackson, a county over in Ocean County. Whether the crawl space sits under a borough Victorian or a township ranch, the same inspection and installation crew handle it.
There is no fixed number we can promise. What holds it up over time is a correct install, seams taped, the rim joist covered, vents actually sealed rather than just closed. Beyond that, use and whatever happens in the crawl space afterward play a role. On any later visit to a Freehold property, we will take a look at how the barrier is holding.
Free inspection and a written estimate, no obligation.
