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!

Attic Services
Cliffside Park is one of Bergen County's densest boroughs, and much of its housing is the two-family frame construction built in the 1920s through the 1940s, one attic often sitting over two separate households. Insulation up there is usually original, well under what's now recommended for Bergen County attics, and the flat porch roofs common on these lots let heat escape unevenly enough to ice up at the edge some winters.

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 Cliffside Park Attics & Crawl Spaces
Cliffside Park packs roughly 25,000 people into about one square mile, atop the Palisades, and most of that density is two-family and multi-family frame houses built in the 1920s through the 1940s. Lots are tight, attics are often shared between two households, and the borough's building boom predates any modern insulation standard.
Two-family frame houses built here from the 1920s through the 1940s often share one attic between both units, still holding close to what went in when the house was built.
Most below-grade space here is a full basement, not a crawl space, but Bergen County's clay soil keeps rim joists and the occasional crawl space damp enough to sag insulation.
Rowhouses and two-family homes sit close enough here that mice move attic to attic along shared roof lines and party walls once they find a gap at an old vent.
Cliffside Park sits exposed along the Palisades ridge, where wind finds every air leak, melting snow unevenly on the flat porch roofs common here and building ice at the eaves.

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 do mice get into a Cliffside Park attic?
Listen for scratching along the ceiling at dawn and dusk, and check for droppings and torn nesting material near the eaves. In Cliffside Park's rowhouses and two-family frame houses, mice usually move in along a shared roof line or through a gap at an old vent or soffit, since the buildings sit close enough for one opening to reach several attics at once. We seal that opening, remove any contaminated insulation, and sanitize before replacing it.
How long does an attic job take in a Cliffside Park two-family?
A straightforward insulation job in one of these attics typically wraps in a single visit. It takes more time when the crew also has to remove old or rodent-contaminated insulation first, which is common in the borough's older two-family houses, or when the shared attic layout means working around two households' schedules. You will know the exact scope before the crew starts.
Why do flat porch roofs in Cliffside Park get ice buildup?
Flat and low-slope roofs are common over porches and additions on tight Cliffside Park lots, and they read heat loss differently than a pitched roof does. Warm air leaking up from an unsealed attic collects under that flat deck and melts the layer of snow touching it, which then refreezes at the cold edge and backs up under the roofing. Sealing the attic air leaks first is the part that actually changes the pattern.
Are there rebates for insulation upgrades in Cliffside Park?
Cliffside Park is PSE&G territory for both electric and gas, and insulation and air sealing upgrades can qualify for rebates through the statewide NJ Clean Energy Program. Availability and amounts move around, so the most reliable way to know what applies to your project is to ask during the free estimate, we track the current offerings.
How much insulation does an attic need in a Cliffside Park two-family?
Current guidance calls for a lot more insulation than most Bergen County attics were originally built with, and how much a specific attic actually needs is something the walk-through inspection sorts out. Most attics we open in Cliffside Park's two-family houses hold only what went in when the house was built in the 1920s through the 1940s, well short of that guidance, and because one attic often serves both units, the gap affects two households' bills at once.
Does encapsulation matter if my Cliffside Park house only has a basement?
Most Cliffside Park rowhouses and two-family frame houses were built with a full basement rather than a crawl space, so encapsulation in the strict sense applies mainly to rear additions or porches built onto a sloped lot. Bergen County's clay soil still keeps the rim joist damp in either case, and that is where we focus, sealing the band around the foundation and insulating it correctly.
Do you serve towns around Cliffside Park?
Yes. We run daily through the Bergen County towns bordering Cliffside Park, Fairview, Edgewater, Fort Lee and Ridgefield, and just across the county line into Hudson County for North Bergen. Further up the ridge we also cover Englewood. Reach out even if your town is not named here, chances are we already cover it.
I live in a two-family house in Cliffside Park, can only my side get insulation work?
Often, yes, if the attic has a partition or the insulation can be added unit by unit, but many older Cliffside Park two-families share one open attic across the full roofline with no dividing wall up there. In that case we look at the whole space during the estimate and explain what can be treated separately versus what only makes sense done once for both units.
