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
Ridgewood's older sections, the Heights, Floral Park and Old Country Club, filled in during the early 1900s with Tudors, foursquares and Colonial Revivals, many finished out with a third-floor attic room and kneewalls rather than open rafters. Those attics were rarely brought past what builders used then, a couple inches of loose fill. Bringing one up to what current guidance calls for starts with sealing the kneewall and chase gaps, then blowing fresh insulation over what is already there.

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 Ridgewood Attics & Crawl Spaces
Ridgewood grew from a farm crossroads into a commuter suburb almost entirely between the 1890s and the 1930s, when the Heights, Floral Park and Old Country Club filled in with Tudors, foursquares and Colonial Revivals built along the new rail line. Those houses were built to last, just to standards from before modern insulation and ventilation existed.
Many attics in the Heights and Floral Park have only the thin fill that went in when the house was framed, well short of what today's standard calls for.
Full basements here usually rest on old stone or rubble walls, and the crawl spaces that do exist are almost always under a later addition that traps moisture against the framing.
Mature tree canopy over streets like the Heights puts squirrels and raccoons at roof height, where soffits, ridge gaps and slate eave edges have loosened enough over a century for bats too.
Ridgewood's steep-pitched Tudor and Colonial Revival roofs shed snow unevenly when attic heat escapes, building ice at the eaves instead of at a simple ridge line.

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 insulation does a Ridgewood attic actually need?
What New Jersey now expects in an attic runs well past what most older Ridgewood attics were ever given, and the right number for yours depends on what is already there and how the space is put together, something the inspection settles. Many Ridgewood attics, especially in the Heights and Floral Park, are still working with whatever thin layer of fill the original builders used a century ago, sometimes with nothing at all over the kneewalls.
My house has a stone foundation and a dirt crawl space under one wing, does encapsulation make sense?
Yes, and it is actually the more common call in Ridgewood than a full crawl space house. A lot of the older homes here have a real basement under the main block and a smaller crawl space under a later sunporch or mudroom addition, and that add-on section is usually the one drawing in moisture and losing heat. Sealing and encapsulating just that space closes the gap without touching the rest of the foundation.
Are there NJ rebates for insulation upgrades in Ridgewood?
Ridgewood is served by PSE&G, and insulation and air sealing upgrades are a regular category under the statewide NJ Clean Energy Program. Program details and rebate amounts change, so the most reliable step is asking what is currently available when we come out for your free estimate.
My attic still has old knob-and-tube wiring, is it safe to add insulation?
It is something we plan around rather than something that stops the job. A fair number of Ridgewood's early-1900s attics still have exposed knob-and-tube runs, and covering that wiring with insulation without addressing it first is a real fire risk, so we work around active runs, flag anything that looks compromised, and keep insulation clear of exposed splices. It is not an electrical repair we perform, just care we build into how the attic gets insulated.
What are the signs I have squirrels, raccoons or even bats in my Ridgewood attic?
Scratching or thumping around dawn and dusk, droppings along the joists, and insulation pulled into a nest are the usual signs, along with a high-pitched squeaking if bats have moved in behind the eaves. In Ridgewood the entry point is almost always up at the roofline, where century-old soffits, ridge gaps and slate eave edges have opened up enough for something to squeeze through.
How long does insulation work take in an older Ridgewood house?
It depends more on access than how big the attic is. A Colonial Revival with open rafters tends to move quickly, but a Tudor with a finished third floor and kneewalls takes longer because the crew has to work insulation into spaces a straight attic never has, and rodent contamination or old insulation that needs pulling first adds more time still. The schedule you actually get comes with your written estimate.
Which Bergen County towns near Ridgewood do you cover?
We work throughout Bergen County, with Glen Rock, Midland Park, Ho-Ho-Kus, Wyckoff, Waldwick and Paramus among the towns right around Ridgewood where our crews are out regularly. If your town borders Ridgewood, assume we cover it and ask us to confirm on the call.
Do steep old Ridgewood roofs get ice dams, and is that a roofing problem?
It is almost never the roof itself. Ridgewood's Tudors and Colonial Revivals have steep, complicated rooflines, and when attic heat escapes through gaps at the top plates or old duct chases, it melts snow from underneath even while the eaves stay frozen, building a dam that backs water under the shingles or slate. Sealing those attic air leaks addresses the cause instead of the roof surface where the water shows up.
