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
South Plainfield's population jumped from about eight thousand to nearly eighteen thousand between 1950 and 1960, and the capes, ranches and split-levels built through that boom in Avon Park, Holly Park and near Samptown were finished to standards set long before today's attic targets. Getting one caught up to what today's guidance expects starts with sealing the top-plate air leaks, then building fresh insulation over them.

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 South Plainfield Attics & Crawl Spaces
South Plainfield's population grew from about eight thousand to nearly eighteen thousand in the 1950s alone, and most of the borough's capes, ranches and split-levels trace back to that single decade. They were solid builds for their time, just insulated to standards set long before today's targets for this part of New Jersey.
Most South Plainfield attics were framed during the borough's population boom and still hold close to their original insulation, well under what today's guidance calls for.
Ground near the Barnes Preserve and the Bound Brook headwaters keeps the water table high, and crawl spaces there draw in humid air through open vents most of the year.
Wetlands along the Barnes Preserve keep squirrels and raccoons active near rooflines borough-wide, and aging soffit seams on 1950s-built capes and ranches have started to separate with age.
Capes with a finished half-story vent poorly around the kneewalls, so warm air leaking past them melts roof snow unevenly and refreezes into ice dams along the eaves each winter.

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 South Plainfield attic actually need?
Current standards call for considerably more depth than most attics of this age were ever originally built with, and the right target for your house depends on what the inspection finds up there. Most of the capes and ranches we open here, especially in Avon Park and Holly Park, are still running on what went in when the borough was built out in the 1950s, a fraction of what current guidance calls for.
Why do crawl spaces near the Barnes Preserve stay so damp?
The preserve marks the headwaters of the Bound Brook, and the lower-lying streets nearby sit close to that water table. Vented crawl spaces pull humid air in through the openings all season, which is why insulation comes loose from the joists and floors above start to feel cool and musty. A sealed vapor barrier closes off both the vents and the ground.
Are there rebates for insulation upgrades in South Plainfield?
South Plainfield is PSE&G territory, and between the statewide NJ Clean Energy Program and occasional PSE&G-specific offers, insulation and air sealing rebates do come around. Availability and amounts shift from program to program, so ask us what is currently open when we come out for the free estimate.
Why does the upstairs of my South Plainfield cape run so hot in summer?
Capes with a finished half-story depend on the small kneewall attics tucked behind the knee walls, and those triangular spaces are often the last part of the house anyone thinks to check. When they are thin or gapped, heat pools under the roof deck and pushes straight into the bedrooms below. Insulating and sealing those kneewall spaces is usually what fixes it.
What does a rodent problem look like in a South Plainfield attic?
Scratching or running sounds around dusk, droppings scattered along the joists, chewed wiring, and insulation pulled into a nest. Squirrels and raccoons here tend to come in off the tree cover near the Barnes Preserve, working through soffit seams that have loosened on capes built in the 1950s and 60s.
How long does insulation work take in a typical South Plainfield cape or split-level?
A single-story cape or ranch attic usually moves along quickly once the crew has access. Split-levels take a bit longer because the attic space is broken into sections, and pulling out old insulation first or cleaning up rodent damage stretches the job out further. The written estimate lays out what to expect for your house.
Do you serve towns around South Plainfield too?
Yes, we work throughout Middlesex County as well as the bordering Union County towns, reaching Edison, Piscataway, Plainfield, Scotch Plains, Dunellen and Metuchen along with South Plainfield itself. Our crews are out in this part of central New Jersey on a regular basis, so scheduling an estimate nearby is usually quick.
