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!

Insulating a Bergenfield Crawl Space Floor
A crawl space with no insulation loses heat straight through the floor above it. That is the case Master Attic runs into most in Bergenfield: not the main house, which usually has a full basement, but the room added on later, built with its own crawl space and, more often than not, nothing between the joists at all.
Nothing gets installed on a guess. The bays get looked at first. Loose, missing or slipped material gets pulled out, and the rim joist and sill get closed off, since a batt laid over an open seam only solves half the problem. Once that groundwork is finished, fresh material fills the floor to what this part of New Jersey expects today, fastened so it actually stays put through a Bergen County winter.
What comes back is a number in writing, not a verbal guess: whether removal comes first, how the perimeter gets handled, and which material makes sense for that specific space. A property with a basement under the original house and an addition sitting on its own crawl space might only need the second half touched, and the walk-through is what settles that.

What We Find in Bergenfield Crawl Spaces
What tends to be behind most new crawlspace insulation calls we get in Bergenfield, NJ.
Plenty of Bergenfield's addition floors went up empty, since insulating that kind of add-on was not standard practice at the time. The room built above has lost heat directly into open air ever since, sometimes for decades before anyone checks underneath.
Batts between the joists often stop right at the sill, leaving the rim joist bare. That narrow strip runs the full perimeter of a Bergenfield crawl space and cancels out a real share of whatever insulation sits right beside it.
Near Cooper's Pond and the lower ground toward the Hackensack River, a vented crawl space stays humid enough that batts installed years back have usually let go of the joists by the time anyone calls, well before it is visible from the floor above.
Once insulation sags low enough to touch the ground under a Bergenfield addition, it becomes exactly the kind of shelter a mouse looks for, and that material has to be pulled and checked before the bay next to it gets filled.

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.
New Crawlspace Insulation in Bergenfield: Questions We Get
What goes into a new crawl space insulation job for a Bergenfield addition?
A look at the joist bays and the rim joist, gaps around the sill closed off, then batts fitted across the floor to today's standard for this area. It is a routine call on Bergenfield's later additions, rooms tacked onto an older cape or colonial with a crawl space that was framed and closed up bare underneath.
How long should a job like this take?
An empty, ready set of bays moves quickly. Material that needs pulling out first, a perimeter that needs proper wrapping, or a tighter addition opening all add time. We would rather give an honest number at the estimate than a guess before anyone has actually been underneath.
Is there a New Jersey rebate for this kind of work in Bergenfield?
PSE&G serves Bergenfield households, and insulation upgrades that reach into crawl space work have qualified for NJ Clean Energy Program support at different points. What applies to a given project depends on the guidelines active when you book, something worth checking together at the estimate.
Does the crawl space under my addition need different treatment than the basement?
The material itself does not change, but the starting point usually does. A basement that came with the original house is typically conditioned space from the start, while an addition's crawl space went up on its own foundation, sometimes with nothing insulating the floor at all, and gets evaluated as its own project.
How do you tell whether a Bergenfield crawl space is ready for new insulation?
What is already sitting in the bays gets checked first, along with the rim joist and any sign of moisture or rodent activity. That tells us if it is a straightforward install or if pulling old material and sealing gaps has to happen before anything new goes down.
Should old material always come out before new insulation goes in?
If it is wet, loose or carries signs that rodents were living in it, yes, since fresh batts against damaged material will not hold up long term. Material that has stayed dry and properly fastened can often stay right where it is while more gets built on top of it.
What Bergen County towns near Bergenfield get this same kind of work?
From Bergenfield we regularly reach Englewood, Dumont, Cresskill, Teaneck, Tenafly and New Milford, plus the wider county beyond them. A crawl space with no floor insulation under an addition is not a Bergenfield-only issue; it turns up in the same housing stock across that whole stretch.
Does encapsulation belong in the same job as new insulation?
Depends on the crawl space. A vented, damp one usually needs both, since new insulation by itself will not stop moisture from working back in. Whether a particular addition needs the barrier too gets decided on the walk-through, not settled ahead of time over the phone.
