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!

Crawlspace & Basement Cleanup in Princeton Junction
Crawlspace and basement cleanup in Princeton Junction covers two different kinds of space that show up in town in roughly equal measure: the vented crawl spaces that sit under Windsor Hunt's split-level and raised-ranch houses, and the full basements under most of the colonials built from the 1960s on. Both collect the same kinds of problems over enough years, just in different amounts and locations.
A typical cleanup clears out debris, insulation gone soft or moldy with damp, and anything left behind by whatever has been living down there, then sanitizes the space so a musty smell or a scattering of droppings does not keep coming back after the visible mess is gone. Water stains or standing moisture get noted as part of the same trip, since a cleanup that ignores the source just resets the clock on the same problem.
How much cleanup a specific crawl space or basement needs depends on how long it has gone unattended and what has been getting into it, which the inspection covers before the estimate is written. The estimate is free either way, whether the job is a quick clearing out or a fuller cleanup ahead of new insulation or a vapor barrier.

What We Find in Princeton Junction Crawl Spaces and Basements
The four conditions behind most crawlspace and basement cleanup calls in Princeton Junction.
A basement or crawl space holding onto moisture for a while tends to announce itself upstairs first, a persistent staleness in the air that no amount of opening windows in the room above seems to clear. By the time anyone notices it, the source has usually been sitting for a season or more.
Once insulation drops from the joists in a Windsor Hunt crawl space or a colonial's basement ceiling, it tends to gather whatever else has been sitting nearby, dust, old building material, sometimes nesting debris, into one pile that a straightforward sweep will not fully clear.
A crawl space or basement with droppings scattered along the joists or foundation sill has usually had more than one animal pass through over time, not a single incident, and a cleanup that only clears the mess without checking the entry point tends to see the same problem return.
Discoloration on a foundation wall, floor joist or subfloor is a record of where water has been getting in, and it is usually the first thing we check before starting a cleanup, since clearing debris without addressing where the moisture came from just delays the same mess from building back up.

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.
Crawlspace & Basement Cleanup in Princeton Junction: Questions We Get
What does a crawlspace or basement cleanup actually involve in a Princeton Junction house?
Debris and fallen or contaminated insulation come out first, along with whatever a rodent or raccoon left behind, then the space gets sanitized so a musty smell or scattered droppings do not linger after the visible mess is gone. Water staining or an active moisture source gets flagged as part of the same trip rather than ignored.
From start to finish, how long does clearing out a crawl space or basement usually take?
How long the space has gone without attention is the biggest factor in the schedule. A light cleanup with minimal debris moves quickly, while a basement or crawl space carrying multiple seasons of fallen insulation, standing moisture or a wildlife history takes longer to clear properly. Your written estimate spells out the timeline for that specific space before anyone starts.
Are there rebates that apply to crawlspace or basement cleanup in West Windsor?
A cleanup by itself is not the rebated step, but West Windsor falls under PSE&G's service area, and any insulation or vapor barrier work added afterward can sometimes draw on utility efficiency incentives. Exactly what applies gets sorted out once we know what the space itself needs.
What's the difference between cleaning a crawl space and cleaning a basement in Princeton Junction?
A crawl space cleanup usually deals with a smaller, harder to access area where ground moisture and vent gaps are the main drivers, the sort of layout found under most of Windsor Hunt. A basement cleanup covers more open floor space and often follows a water event or a longer stretch without attention, common under the colonials that make up most of the rest of town.
How do you decide how much cleanup a crawl space or basement needs?
The inspection looks at how much debris and old insulation is down there, whether wildlife has been using the space, and where any moisture is coming from, before recommending a plan. A basement under a colonial and a vented crawl space under a raised ranch rarely need exactly the same scope of work.
Do you install new insulation or a vapor barrier as part of the cleanup?
Not automatically, but it often makes sense once the space is cleared, sanitized and dry, since insulation or a vapor barrier going in over a clean crawl space or basement holds up far better than material installed over debris. Whether either one is worth adding gets discussed at the inspection, before anything is decided.
What other Mercer County towns do you clean out crawl spaces and basements in?
West Windsor is not the only stop for crawlspace and basement cleanup calls out of Princeton Junction. Cranbury, Hightstown, East Windsor, Princeton and Plainsboro get the same crews on a regular basis, and Route 1 extends that coverage up into North Brunswick in Middlesex County.
How often does a crawl space or basement need to be cleaned out?
It depends on how the space is built and what keeps getting into it. A well-sealed space with no active moisture or wildlife problem can go a long stretch without needing another cleanup, while a vented crawl space with a recurring humidity or rodent issue tends to need attention again sooner. The inspection is what tells you which situation your house is in.
