Review by in Middletown, NJ
I had originally hired Jeff to remodel my master bath and then it literally became my entire house. Roof, siding, hardscaping, driveway, floors, 3 baths, den, laundry room and most recently a full gut and remodel of my kitchen. I cannot say enough about Jeff and his team. Timely, efficient, clean, they smooth seamlessly from one task to another, able to make changes mid stream, total pleasure to work with. I am sad I have no more projects left! I cannot say enough about Marathon construction, all the guys and Jeff. They care and it shows!!!

Review by in Morganville, NJ
Upon meeting with Jeff both me and my wife knew this was the guy for two of our bathroom remodels. A few contractors came for estimates and Jeff was the most personal and beat both estimates with ease. Upon starting the jobs they were always on time and professional. They cleaned up on a daily basis being that we were living through these two remodels and made sure nothing was damaged during the demo portion. Jeff isn t one of those sell the jobs and you never see him again contractor he is literally hands on and on the job daily and makes sure everything is going good in a timely fashion. He also picks up his phone at all times of the day and makes sure your extremely comfortable with what s going on and makes sure you love everything from start to finish. Not only did I meet a very knowledgeable honest contractor but at the end of the two jobs I gained a good friend. I definitely highly recommend him for any bathroom/kitchen remodel and will definitely be using him in the future for my own kitchen remodel.

Review by in Manalapan, NJ
We were nervous about doing major kitchen remodeling and adding a large sun room.... We have heard many horror stories. However, Jeff and his crew quickly showed us that it is possible to find a professional, diligent, punctual and experienced contractor who can do quality work in a timely manner and at a fair price. We love our new kitchen and sun room. Thank you, Jeff.

Project: Remodel a Bathroom
Without exaggeration, Jeff and his crew went above and beyond to make our bathroom renovation project a perfect showpiece. Jeff prides himself in being exact with his work. It was an extremely difficult original bathroom from the 1930s on the upper floor of a cape cod with funky walls, tight spaces, and a cast iron tub. We wound up with a room that's beyond what we hoped, has amazing tile work, everything solid and sharp. They didn't flinch when we accidentally bought another cast iron tub that had to be maneuvered into that crazy small space -- and it's in perfectly level -- better than the original tub. We chose a very nonstandard tile for both the tub area and floors and instead of being put off by the extra complications, they were excited about the possibilities. We've done a considerable amount of renovation and remodeling work ourselves -- renovated entire homes from the ground up, inside and out. We wanted a company that would work with the same attention to detail and quality that we do. Marathon was much more than that. They're extremely knowledgable, patient, respectful, professional, and we will absolutely use Marathon again for any upcoming projects without hesitation!

Jeff and his team are quick, efficient and very trustworthy. I bought a fixer upper and he understood my vision from the start. I am extremely pleased with his work and would highly recommend Marathon Construction!

Review by in Eatontown, NJ
I had my entire first floor renovated by Marathon Construction, including my kitchen, living room, dining room, family room, powder room, laundry room and front entry. Everything turned out amazing! I could not be more pleased. Jeff and his crew were professional, meticulous, courteous and accommodating. They take great pride in their work and do not cut corners. Jeff is the most ethical businessman I have ever worked with. I am so happy with Marathon Construction that I have hired them to renovate my entire 2nd floor as well.

Review by in Englishtown, NJ
Working with Jeff was a pleasure. He was always open and honest and very fair on his pricing. He was always on time and gave great design tips during the addition. We consistently kept changing design scope on him, and was still able to meet the timeline we discussed. I would highly recommend Jeff for any remodeling/addition/new home build you would be looking to do. Extremely professional and courteous.

Review by in Jackson, NJ
Jeff is fantastic to work with. I would highly recommend him and his crew even though one of his subs had an accident and spilled water resulting in having to paint the kitchen ceiling. Jeff made good on his commitment to fix it and had the entire ceiling painted. We love what he designed for our bathroom and couldn't be happier.

    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
