Encapsulation in Yardley means covering the crawl space ground and every wall with a heavy sealed liner so moisture stops working its way up into the joists, the subfloor and eventually the air above. Being this close to the river and the old canal, the borough's older sections deal with a soil moisture load that towns further inland rarely see, and a fieldstone or brick foundation from that era rarely came with any barrier built in at all. Lower Makefield's newer developments use poured block more often, which handles bulk water better but still breathes humidity through the wall and any vented opening left uncovered. What encapsulation solves is that everyday dampness, which is a different problem than a crawl space genuinely underwater; a space still holding floodwater needs it pumped and the ground dried before a liner is ever on the table.
The floor gets covered edge to edge first, seams taped and the liner run up every wall and pier to a sealed termination point. Foundation vents and the crawl door get closed off or sealed rather than left open to outside air, since a vented crawl space just pulls the same humid air back in every summer. Where the existing insulation has already gone soft or moldy from years of that moisture, it comes out before the barrier goes down, not after.
Every crawl space calls for something a little different depending on its size, its foundation type and how much moisture is already sitting on the ground, so the estimate is built around what the inspection actually finds rather than a standard package. It is free, written and covers the vapor barrier, the sealing work and any insulation replacement the space still needs once it is dry.

Four recurring reasons a Yardley crawl space ends up needing encapsulation.
Sitting this close to both the river and the canal, Yardley's soil rarely dries out the way ground further from the water does, and a vented crawl space pulls that extra humidity straight inside. That moisture works into the wood framing long before anyone notices a smell upstairs.
The historic district's older foundations are mostly fieldstone or brick, laid without any real moisture barrier, while Lower Makefield's developments sit on poured block that handles bulk water better but still breathes humidity through the wall itself. Encapsulation gets fitted to whichever one is underneath.
Crawl space insulation exposed to years of ground moisture goes soft, drops away from the subfloor and eventually grows mold, which is why so much of what we pull out during an encapsulation job is not salvageable. New insulation only goes back in once the space is dry and sealed.
Foundation vents built to code decades ago now do the opposite of what a crawl space needs, drawing in humid outside air all summer and giving squirrels, mice and the occasional groundhog a way into the crawl space itself. Sealing them is part of what makes encapsulation work.
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.
We line the floor and walls with a heavy vapor barrier, seal every foundation vent and the crawl door, and address any insulation that has already been damaged by ground moisture. Historic district crawl spaces usually need extra attention at an older fieldstone or brick foundation wall, while a Lower Makefield crawl space on poured block seals up faster once the vents are closed off.
Prep work plays into it more than anything else. A dry, accessible crawl space with sound insulation moves quickly, while a larger space, wet ground or insulation that needs pulling first adds time. Your specific timeline gets spelled out in the written estimate before any work starts.
Yes, in the sealing details. A fieldstone or brick foundation wall from the 1800s has more joints and an uneven surface to seal the barrier against, while a Lower Makefield poured block wall is more uniform and usually faster to finish. Both foundation types get the same floor to wall coverage in the end.
There is no maintenance schedule to keep, the liner is a permanent fixture rather than a wear item. What can change things years down the line is the building itself: a fieldstone foundation settling slightly, or a seam near a pier getting disturbed if other work happens under the house later. Because our crews end up back under Yardley properties for other reasons fairly often, an encapsulated crawl space usually gets a quick look whenever that happens, rather than being forgotten about once the job is done.
The inspection looks at what kind of foundation is underneath, how saturated the ground or framing already is, whether the existing insulation is salvageable, and how the space is currently vented. Two crawl spaces on the same Yardley street can need noticeably different work depending on grading, foundation age and how the water table sits underneath them.
When it does, yes. Insulation that has gone soft, moldy or fallen away from years of ground moisture gets removed first, because sealing a vapor barrier over damaged material just traps the problem underneath it. Dry, sound insulation can sometimes stay in place while the rest of the crawl space gets sealed around it.
Langhorne, Newtown, Washington Crossing, Middletown Township and Morrisville are all regular stops, along with Bensalem and the rest of the eastern Pennsylvania towns Master Attic serves. A crawl space job anywhere in this stretch of Bucks County gets the same crew and the same materials.
It can be done together or separately, depending on the budget and what the inspection finds. Some Yardley crawl spaces just need the ground and walls sealed because the existing insulation held up fine, while others need new insulation once the space is dry. We quote both so it is your choice how to sequence it.
