Rodent proofing in Princeton Junction means closing the roofline and crawl space openings a rodent actually used, not chasing the animal after it is already inside. Squirrels and raccoons follow the hardwood tree cover that still edges Grovers Mill and Wellington Estates down onto the roof, then work at a soffit or fascia gap until it opens. Around Windsor Hunt, where split-level and raised-ranch houses sit low over a crawl space, the same pressure shows up at ground level instead, at the vents and skirting rather than the eaves.
Once an opening is confirmed, whatever used it, mice, squirrels, raccoons or bats, gets cleared out first. The opening then gets sealed for good, galvanized mesh, sheet metal or sealant sized to that specific gap instead of a generic patch over the whole soffit run, so nothing can use it again before the visit moves on to anything else. Only then does any insulation ruined by the nesting get pulled and the area sanitized.
The number of openings on a given attic or crawl space, and what closing them actually takes, is not something we guess at over the phone, it is what the inspection is for. A 1920s Berrien City original with one soffit gap is a different job than a bigger colonial near the newer sections with several points of entry, and both get a free written estimate before anything starts.
The related work that most often comes up once an opening is found and sealed in Princeton Junction, every visit starting with a free inspection.
The four conditions that bring us out for rodent proofing work across Princeton Junction most often.
West Windsor's old farmland left behind a hardwood tree canopy that still edges Grovers Mill and Wellington Estates, and squirrels and raccoons ride those branches straight onto the roof. From there, a loose soffit joint on an older Berrien City house is usually all it takes to get inside.
Not every Princeton Junction rodent problem starts at the roof. Windsor Hunt is full of split-level and raised-ranch houses over vented crawl spaces, and mice work through those same vents that let in summer humidity, nesting along the rim joist where nobody notices until the smell reaches the floor above.
Insulation that a rodent has nested in does not get reused. Once the opening it used is sealed for good, that section comes out, whether it is a stretch of attic floor over a colonial's bonus room or the batts along a crawl space rim joist, and the area gets sanitized before any new material goes in.
Cold weather pushes wildlife toward the warmest gap it can find, and an attic over a heated Princeton Junction living room is exactly that. Squirrels and raccoons that spent the fall working a soffit joint tend to move in once the first hard freeze hits, and an opening found in October rarely waits until spring.
Better insulation. Sealed gaps. Cleaner air. Lower bills.

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.
It starts with finding every active opening, whether that is a soffit or fascia gap on the roofline or a vent along a crawl space foundation. Once the opening is confirmed, whatever is using it is removed along with what it nested in, and the gap itself gets closed with material sized to fit it, not a patch stretched over the whole run.
Two things move the needle: the count of active openings, and the condition of whatever material sits around them. A single soffit gap on a straightforward attic goes quickly, while a job that also needs contaminated insulation removed or crawl space skirting rebuilt takes longer. That estimate spells out the expected timeline before a crew is booked.
Rodent proofing on its own is not usually a rebate line item, but the insulation or air sealing work that often follows it can be. West Windsor sits in PSE&G's territory, where New Jersey's Clean Energy Program sometimes layers additional incentives on top of what PSE&G already offers. We will check what currently qualifies once we understand the full scope of the job.
Heavy thumping and scratching around dawn and dusk tends to mean a squirrel or raccoon came in through the roofline, while quieter scurrying at night and small droppings scattered along the joists point toward mice, which more often work in at a foundation gap or a sill. The inspection confirms which one it is before we recommend anything.
The walkthrough covers the entire roofline and foundation, not only the spot where droppings turned up, because a Princeton Junction house with one active opening usually has one or two more that have not been used yet. Every gap gets marked, and the estimate covers all of them so a second call for a different opening a season later does not happen.
Sealing happens first: the opening gets closed for good so nothing can slip back in, and that holds true for the entire visit, not just the beginning of it. Only where a rodent actually nested in the insulation does that material come out afterward, pulled and the area sanitized once the seal is already in place. Insulation that has not been touched can usually stay exactly where it is.
A squirrel, raccoon or mouse has no idea where West Windsor ends, so our rodent proofing calls run all over Mercer County: Princeton, Plainsboro, East Windsor, Hightstown and Cranbury are all regular stops, and Route 1 carries us as far as North Brunswick in Middlesex County.
Not on its own. A roofline seal stops what is coming in above, but a Princeton Junction crawl space with vents or skirting gaps still has its own way in from the ground, particularly on the split-level and raised-ranch houses near Windsor Hunt. We check both areas during the same inspection and treat them as separate openings even when the same trip covers both.
Free inspection and a written estimate, no obligation.
