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!

Paramus nearly quadrupled in population during the 1950s building boom, and most of the split-levels and colonials from that decade have never had their attic insulation touched, batts far thinner than what today's guidance expects in this stretch of North Jersey. Getting a seventy-year-old attic like that current is a two-part job: close the air leaks at the top plates and duct chases, then bury them under fresh blown-in insulation.

Squirrels chew wiring and tear up insulation once they get into an attic. We remove them and close the entry points.
Squirrel Removal →A raccoon can wreck attic insulation and ductwork in weeks and leave dangerous droppings behind. Safe removal plus repair of the damage.
Raccoon Removal →Bats roost in quiet attic corners and their droppings contaminate everything below. Humane exclusion plus full cleanup.
Bat Removal →Mice squeeze in through gaps the width of a pencil, nest in the insulation and leave droppings across the attic floor. Removal, then sealing the gaps so they stay out.
Attic Mice Removal →Wildlife tears openings where the roof meets the walls, and every gap is an open door. We seal the entry points and repair the damage.
Rodent Proofing →Thin, patchy insulation lets heated and cooled air escape into the attic all year. Upgrading it cuts energy bills.
Attic Insulation →Moisture in the crawl space feeds mold and rots the framing under your floor. Encapsulation seals out the damp ground air.
Crawl Space Encapsulation →New batts fill every joist bay edge to edge, so heated and cooled air stays in the rooms below instead of bleeding into the attic. Lower bills, even temperatures.
Attic Insulation →A vented ridge lets hot, moist air escape at the peak while baffles keep the soffit intake open. Balanced airflow protects the roof deck and keeps the new insulation dry.
Attic Ventilation →The roofline gap the wildlife used is sealed with rodent-proof mesh and sealant, along with every other opening we found. Nothing gets back in.
Rodent Proofing →Droppings, nesting debris and the contaminated insulation are gone, and the framing is treated so odors and bacteria do not linger in the air you breathe.
Attic Cleanup →A sealed vapor barrier covers the ground and walls, so damp soil air can no longer feed mold or rot the floor framing above it.
Crawl Space Encapsulation →What is going wrong here
- Thin, patchy attic insulation lets heated and cooled air leak up into the attic, and the energy bill pays for every bit of it.
- Warm air pours out through the roofline gap and the ridge instead of staying where it belongs.
- Squirrels, raccoons, bats and mice have moved in; droppings and nesting cover the attic floor.
- Damp ground air rises through the crawl space and feeds mold under the floor.
What changed
- Full-depth insulation keeps conditioned air in the living space where it belongs.
- Warm attic air stays upstairs and vents out at the ridge the way it should.
- Every entry point is sealed and the attic is cleaned and sanitized; nothing lives up there but insulation.
- The crawl space is sealed and dry, so ground moisture stays in the ground.
Built Around Paramus Attics & Crawl Spaces
Paramus went from a farm township of a few thousand people to a built-out suburb of over 20,000 in about a decade, and most of that building happened before modern insulation codes existed. That single fact explains why so many Paramus attics and crawl spaces are original to houses now pushing seventy years old.
Most Paramus attics still carry the batts installed when the house went up in the 1950s or 60s, well short of the target current guidance sets now.
Split-level construction here often sets one wing over a crawl space, and Bergen County's water table keeps that ground damp enough to sag insulation out of the joists.
Older sections like Spring Valley and Dunkerhook carry mature trees that put squirrels and raccoons at roof level, where aging soffits give them an easy way in.
Bergen County averages close to double the snowfall of South Jersey, and a leaky attic here melts snow unevenly enough to build ice dams at the eaves most winters.

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.

Frequently Asked Questions
How much attic insulation does a Paramus home need?
The current guidance for an unfinished attic in North Jersey calls for real depth, well beyond what these attics were originally given. Most attics we open in Paramus fall well short of that, because they still carry the original insulation from when the house was built in the 1950s or 60s. The inspection tells us exactly how far off a given attic is.
My Paramus split-level has a crawl space and a basement, does encapsulation still matter?
Yes. A lot of Paramus split-levels have a finished basement under part of the house and an unfinished crawl space under the rest, and that crawl space is usually the weak point. Bergen County's high water table keeps it damp enough to sag insulation and send musty air upstairs even when the basement itself stays dry.
Are there New Jersey incentives for insulation upgrades in Paramus?
Paramus is PSE&G territory, and insulation and air sealing upgrades have regularly qualified for rebates through the statewide NJ Clean Energy Program. Ask us what is currently on the table when we come out for your estimate, since the specifics are not fixed from one visit to the next.
Can attic air sealing stop ice dams on a Paramus roof?
Usually, yes. Ice dams form when heat leaking into the attic melts roof snow from underneath while the eaves stay cold, and Bergen County sees close to twice the snowfall of South Jersey, so the cycle repeats all winter. Sealing the air leaks at the top plates and ceiling fixtures before adding insulation is what actually stops it, insulation alone will not.
What are the signs of rodents in a Paramus attic?
Listen for scratching at dawn and dusk, and look for droppings along the joists, nesting pockets torn into the insulation, and chewed wiring. In Paramus the entry point is almost always at the roofline, since the mature tree canopy in older sections like Spring Valley and Dunkerhook puts squirrels and raccoons right at the eaves.
How long does an attic project take in a typical Paramus colonial or split-level?
Most straightforward attics move quickly once the crew gets started. A Paramus split-level can take longer when the job also involves hauling out old insulation or cleaning up after rodents, since attic access in these houses tends to be tight. You will have the exact schedule in writing before any work starts.
Which Bergen County towns near Paramus do you serve?
All of Bergen County. Around Paramus itself that means Ridgewood, Fair Lawn, Hackensack, Glen Rock, Oradell and River Edge, where our crews already run daily. The complete town list is on our New Jersey service area page.
What causes a musty smell in a Paramus crawl space?
Almost always moisture. A vented or unsealed crawl space pulls in damp air that condenses against cooler framing, and that trapped moisture is what creates the musty smell and raises the risk of mold over time. A vapor barrier over the ground and walls, with the vents closed, cuts the moisture off at its source.
