Lodi is one of Bergen County's most densely built boroughs, and most of that density is two-family houses from the 1940s and 50s, many sharing one attic under a kneewall half-story. That attic usually still holds the thin batts it was built with, nowhere near what is recommended here now. Getting it current means sealing the party-wall gaps first, then blowing in fresh 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.

What changed
At 2.3 square miles, Lodi is one of Bergen County's smallest, most densely built boroughs, and most of its roughly 26,000 residents live in two-family houses that went up during the borough's 1940s and 50s growth. That density and that housing type explain most of what Master Attic gets called out for here.
Most two-family Lodi attics still hold the thin batts installed when the house went up, a fraction of what is now recommended for attics in this area.
Lodi's two-family houses run mostly on full basements rather than crawl spaces, so an uninsulated rim joist is usually the first place cold air and moisture reach the room above.
Attached two-family construction means a mouse that gets into one attic can move into the attic next door through a shared kneewall or roofline seam, a route this housing creates.
The flat or low-slope roof sections common over Lodi's second-floor units hold melting snow longer than a pitched roof would, and heat leaking up from below starts the melt-refreeze cycle.

BeforeAfterHear What Our Customers Are Saying
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.

Most attics we open in Lodi are still sitting at the thin batts installed when the two-family house went up, often back in the 1940s or 50s.
It changes where the work happens more than what gets done. Most two-family houses here run on full basements, so instead of a vapor barrier under a crawl space, the fix usually starts at the rim joist, the framing band where the basement meets the first floor and where an uninsulated rim joist loses the most heat. If part of the house does sit over a crawl space, we treat that separately with encapsulation.
Lodi is in PSE&G territory, and insulation and air sealing upgrades have periodically qualified for rebates through the statewide NJ Clean Energy Program. Because a two-family house often needs more material than a single-family home of the same footprint, ask us what is currently available when we come out for your free estimate.
They can. A flat or low-slope section over a second-floor unit holds melting snow longer than a pitched roof would, and heat escaping from an uninsulated attic underneath is usually what starts that melt. Sealing the air leaks at the ceiling before adding insulation keeps that section colder and more even through the winter, the strongest defense against ice building up at the edge.
Scratching along the ceiling at night, droppings scattered across the insulation, a nesting pocket torn out of the batts, and chewed wiring are the usual signs. In Lodi's attached two-family houses, mice often move in through a shared kneewall or a gap where a flat roof section meets the main roofline, not through the foundation.
Most attic jobs wrap up in a single visit, longer if old insulation has to come out first or there is rodent contamination to clean up. Shared attics over two-family houses need extra coordination since access usually runs through one unit's hatch for the whole space, so we schedule around both households before work starts.

A kneewall is the short, angled wall separating a room's usable floor space from the low, sloped part of the attic behind it, common in the half-story second units built onto so many Lodi two-family houses. Left uninsulated, that wall is one of the biggest sources of a cold or hot upstairs unit, since it faces the same open attic air as the roof deck above.
Insulation is not just for winter. Here is how the right insulation level keeps summer heat out of your rooms and your cooling bills in check.
