Plumbing reviews in Marshfield, Massachusetts

Mark was quick to respond, upfront about pricing, and was here within a short time. This has been consistent over the years I have used his company. I highly recommend!

On the Mark Plumbing had my pipe fixed within 2 hours of it breaking and me calling after 8 pm… super responsive, nice, and professional. He explained what happened and how he was going to fix it. Everything was fixed quickly and you can’t even tell he was here - expect for the shiny new pipe and replacement valve! Saved me from having to deal with a morning of getting ready for school and work without water!

Mark did a great job! Replaced my well pump and installed a water filter system. It looks great and easy to access.

The entire process from quote to installation went flawlessly. Mark was very responsive and got us a quote in 24 hrs. Jarod arrived and completed the job of removing and replacing our tankless natural gas water heater on the exact date and time promised. I asked about replacing a shower valve and faucet which he also did on the same day.
Great service and very friendly plumbing experience. Highly recommend On the Mark Plumbing Marshfield, he also was the best quote we received from 3 vendors for the same product

Mark is professional smart and fixed our plumbing issues! The best!!! Thanks Mark !

Mark did a great job installing my new central AC along with a high efficient heating system! Would highly recommend!

Mark is the kindest guy I’ve met and worked with. He works with your budget and is fair. He does great work and is promptly on time. Very happy! Thank you!

I cannot say enough good things about Mark and his work in our home. He was so professional, thorough, and knowledgeable. Highly recommend this company!

New customer. We had a no heat situation on one of three zones. Called Mark at 8AM Fri after Thanksgiving. Told him not an emergency, just looking to get on his schedule. He was able to squeeze us in and had the system running fine with a new thermostat by 10:30AM. Can't beat that!

I can’t say enough good things about Mark, he is so knowledgeable and trustworthy. I would recommend him to anyone.

Mark installed a Mitsubishi heat pump. Most competitive bidder, clean, timely competent work. I’d recommend him. Second job he’s done for us , we’re very satisfied

Could not recommend On the Mark Plumbing higher! We have now used them in two homes and will continue to use them. They are clean, courteous on time, and do great work but most importantly for me, I always get an honest breakdown of what the work is - dumbed down for a non-tradesman -, what it will cost, and if it is a NOW, soon, or get to it eventually problem.

On The Mark Plumbing is a one man show of total competence and skill. Mark came to my home and installed a gas combo boiler/tankless hot water heater. I highly recommend him to anybody with confidence. He has incredible expertise in his field, very knowledgeable and he takes the time to do the job right. He answered all of my thousands of questions and always with a smile. He made sure to always lock the bulkhead behind him and left everything clean, probably cleaner than when he arrived! He was extremely receptive when I mentioned the condo association frowns upon driving on the grass, so he walked back and forth from his truck out front to the job site around a long row house building out back countless times. From taking out my old system, to climbing on the roof, to his pipe work, tedious yet flawless, he does it all!

We now have heat and on demand hot water effortlessly, all while saving money. For that, I'm truly thankful!

He's also Mass Save certified. So if you're thinking about going high efficiency to get that rebate, go with Mark! You will be thankful you chose him over the other guys!

Full disclosure: I might be biased since the owner is my brother-in-law, but trust me when I say I wouldn’t be writing this if the work wasn’t great. Not only is he incredibly talented, but his approach to customer service is exceptional. When I first purchased a house, the first thing to go was the waste water pipe in the basement (which is the absolute worst). He helped us manage a dirty job cleanly and efficiently. On the Mark Plumbing, Heating & Cooling is the real deal—highly recommend!

This is the 2nd time I have had to call Mark for an emergency and there is no doubt, On the Mark is the best crew in town. They are pleasant to speak to, very detailed with their work, and Mark is a great guy. 10/10 experience using On the Mark both times.

Mark came by and performed a number of services for me, install a new main water filter, install two hose bibs, and relocate a toilet supply. He was very receptive to some of my requests, and went out of his way to make sure the job was done to my satisfaction. He even consulted with a foundation guy to determine if one of my desires was feasible...turns out it was not advised. His work is exemplary, very clean, and tidy, he left the areas he worked in cleaner then when he started. I would hire him in a hart beat for any other plumbing work.

Mark is one amazing young man with the heart of gold. My daughter and I truly appreciate his timely help Sunday night 10 pmish Eastern time! May God bless him and his family with happiness and health:) Angels do exist ❤️

I have a Rinnai heating system and, after a dozen different heating specialists, Mark is the only one who was able to repair and maintain it. He actually had to correct other heating contractors' work. He is professional, meticulous, and consistent. I am so happy to have found On The Mark!

Mark answered my first call and came out within hours. Great quick service and very reasonably priced, especially same day! Lifesaver!

10 stars!! Same day emergency service during a nor'easter no less. Mark is professional and was on time and explained everything about why the heat stopped working. He is phenomenal. Do not hesitate, call him if you need him!!

Mark has consistently demonstrated exceptional dedication and expertise in his field. Over the years, he has been our go-to expert for a variety of projects, providing invaluable assistance during several urgent situations. His approach is not just professional, but also genuinely passionate, which clearly reflects in the quality of his work.

One of the most impressive aspects of Mark's service is his ability to quickly identify the most efficient, logical, and cost-effective solutions. He's always just a call away, ready to tackle any challenge with a well-equipped and knowledgeable mindset.

What sets On The Mark Plumbing apart is the personalized attention and trustworthiness Mark brings, something that's often missing with larger companies. If you're seeking reliable, top-notch plumbing services, I highly recommend going with Mark. You won't be disappointed!
