Your crawlspace is one of those areas in your home that you don’t often think about, but it is always working hard
Protect your crawl space from moisture, mold, and wood rot with expert encapsulation services in New Jersey, Pennsylvania, and Delaware.
Your crawl space may be out of sight, but it directly impacts your home’s air quality, energy efficiency, and structural integrity. Without proper moisture control, crawl spaces often develop mold, mildew, and rot, leading to expensive repairs and health risks.
Our professional encapsulation system seals out ground moisture, helps eliminate musty odors, and improves long-term home protection from the ground up.
Crawl space encapsulation is the process of sealing your crawlspace with a heavy-duty vapor barrier along the floor and walls. We also seal off vents and gaps to block outside moisture, air leaks, and pests.

I had a great experience dealing with Dan Jones from Master Attic LLC. Dan was extremely professional, knowledgeable, responsive, and genuinely helpful throughout the entire process. What impressed me most was his communication and follow-up — he took the time to explain everything clearly, answer my questions, and continued to follow up afterward without ever making me feel pressured. Dan is very personable and clearly takes pride in what he does. It was a pleasure dealing with someone who approaches customers with this level of professionalism and attention. Dan Jones is an excellent representative of Master Attic LLC, and I would absolutely recommend speaking with him if you’re considering attic work. Five stars for Dan!Posted on Google![]()

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!Posted on Google![]()

Inquire View profile Your team from start to finish was exemplary! Alex's assessment and explanation of my attics situation, and the corrective measures met and exceeded all of my concerns and then some. Jose, once on site, was remarkably thorough in his evaluation of my attic, and addressed all questions and advice eloquently and concisely prior to starting work. Despite a hiccup with their insulation blower (all it needs is an new control board-call me!), everything went amazingly quick! About two hours after your crew left, I already noticed a difference! If I could give you folks SIX STARS, I would.Posted on Google![]()

Very professional job done Jesus, Ronald C, and crew. Tapped down plastic around the entire entrance way, walls and everything. Cleaned up all the garbage and vacuumed the floors after taking the plastic down. Installation of baffles, rodent proofing, and new insulation all completed within about 7hrs. Clear communication throughout the process. Even cleaned up and insulated the crawl space. Was end of July so they worked in the heat as well. Sealed all the air gaps even under the insulation. Sprayed disinfectant spray to remove rodent smell. Installed metal wiring inside any possible openings and even went onto the roof to nail in some loose siding that had gaps.

Moisture barrier encapsulation is the process of sealing off areas—like crawl spaces or basements—with a moisture-resistant barrier (usually heavy-duty plastic sheeting or vapor barriers) to prevent water and vapor intrusion. This creates a controlled environment, reducing the risk of moisture-related issues.
Moisture barrier encapsulation is important because it:
Prevents mold, mildew, and wood rot caused by excess moisture
Protects your home’s structural integrity
Improves indoor air quality by limiting the spread of allergens
Enhances energy efficiency by reducing humidity and HVAC load
Encapsulation is typically installed in:
Crawl spaces
Basements
Under floors in homes built over damp or poorly ventilated ground
These areas are most vulnerable to moisture infiltration from the ground.
Common materials used in encapsulation include:
Heavy-duty polyethylene vapor barriers (6 to 20 mil thickness)
Seam and edge sealing tape
Mechanical fasteners or anchors
Spray foam or rigid foam insulation (optional)
Dehumidifiers for climate control
Drainage systems such as sump pumps or French drains, if needed
