New crawlspace insulation goes into floor joist bays and along the rim joist to slow heat loss through the floor, work that matters most where a crawl space was built without any insulation at all or where what went in originally has since fallen out. In Cherry Hill that covers a wide range of houses: split-levels and ranches from the postwar decades that were built to a lighter standard, and additions or newer construction that sometimes skip the crawl space floor entirely.
We start by seeing what is actually in the bays now, not assuming. Where insulation is missing, loose or has separated from the joists, it comes out first, and any gaps or seams around the rim joist and sill get sealed ahead of anything else, since insulation laid over an open gap only blocks part of the heat loss. New batts then go across the floor to today's standard, held in place properly so the same problem does not happen again.
You get a free, written estimate that says exactly what your crawl space needs: whether old material has to come out first, how the rim joist and sill get handled, and what insulation makes sense for that specific space. The inspection is what decides, not a guess made from the driveway.
Six jobs that tend to come up once we are already under a Cherry Hill crawl space floor, covered in the same free inspection.
Four things that turn up under Cherry Hill crawl space floors more than anything else.
Some Cherry Hill crawl spaces, especially additions and a few of the town's older sections, were built without any floor insulation at all, so the floor above has been losing heat straight into open air since the day it was framed.
Floor insulation between the joists is often installed without ever wrapping the rim joist at the perimeter, which leaves a narrow gap running the length of the crawl space that undoes a good part of the insulation right next to it.
In a vented South Jersey crawl space, batts installed decades ago have had years of summer humidity to work on them, and by the time we are called out most of it has already separated from the joists it was stapled to.
Where insulation has fallen low enough to touch the ground, it turns into shelter mice will use without hesitation, and that material has to be identified and removed before we bring any new insulation anywhere near it.
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 check the joist bays and the rim joist first, seal any gaps or seams around the sill, and then install new fitted batts across the floor to today's standard. In Cherry Hill this comes up often in additions and a handful of older sections built without a floor insulation step at all.
A crawl space with empty, ready joist bays goes fast. One where old material has to come out, the rim joist needs sealing, or access is limited slows things down. We would rather tell you which one yours is at the estimate than guess at it once the crew is already there.
Cherry Hill households are served by PSE&G, where the state's clean energy programs have, at various points, supported insulation upgrades including crawl space work. Whether your project qualifies depends on the guidelines in effect when you book, which we can check with you at the estimate.
It depends on the crawl space: vented and humid ones usually need it, because new insulation alone will not stop moisture from reaching it again. We will tell you during the inspection whether your specific crawl space needs sealing too, or whether insulation on its own is enough.
What is already in the bays. We look at the condition of the rim joist and whether there is moisture or rodent activity to deal with. That tells us whether it is a straightforward new install or whether removal and sealing have to happen first, ahead of any new insulation.
If it is loose, wet or has had rodents in it, yes, because new material against contaminated or damp insulation will not hold up. Insulation that is dry and still properly fastened to the joists can sometimes stay in place while we add to it.
Camden County and the surrounding South Jersey towns, Haddonfield, Voorhees, Marlton and Moorestown among them, are all within our regular coverage. A crawl space missing floor insulation is just as common a call in those towns as it is in Cherry Hill, especially in houses built to the same era and standard.
That is usually the first thing homeowners notice, cold floors in winter directly over an uninsulated or poorly insulated crawl space. Bringing the joist bays and rim joist up to today's standard closes off where that cold was reaching the floor from underneath. Pair it with sealing at the sill and the difference is usually noticeable by the first cold snap after the work is done.
