Reviews of local pros in Marshfield, Massachusetts

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!

Mark is awesome! I had an emergency plumbing issue. I called so many other plumbers who claimed they offer 24/7 emergency service. After I talked to him, he was here in 20 minutes. Super polite and efficient!

Mark was able to help me with my heating system repair when other plumbers couldn't. The repair was done quickly and affordably. I really appreciated the extra time he took to educate me on my system and how I can best care for it ongoing to save money on heating bills and prevent wear and tear on the system. Professional and fast, I highly recommend On the Mark Plumbing! I will for sure be using them again.

I called for a no heat situation. Mark answered my call and was here within the hour. He quickly determined it was a faulty thermocouple which he replaced, all fixed. The repair charge was quite reasonable. I highly recommend On the Mark Plumbing.

We’ve worked with On the Mark Plumbing on several major projects in our home, and we can’t recommend them highly enough. Mark has been incredibly thorough and professional, always taking the time to explain things clearly, answer all of our questions, and guide us through every step. He handled our kitchen remodel, relocated our washer and dryer from upstairs to downstairs, and even laid the groundwork for our future central air system while we were in renovation mode.

Most recently, Joe from Mark’s team installed our outdoor shower, and he did a fantastic job—extremely detailed and professional.

Both Mark and Joe are not only excellent at what they do, but also genuinely kind people. Their combination of skill, reliability, and personable service makes them a team we would recommend a million times over. We’re grateful to have found such a trustworthy company to support our home projects.

Mark came the same day when our burner stopped working, which was such a relief because with three little ones we were nervous! He found the problem within minutes and was able to remedy the situation. He had a great sense of humor when we discovered our kids contributed to the broken burner. He kept everything clean as he was working and he was so professional! We appreciate everything he did and he will always be our go to for emergencies or tune ups!

Mark was very responsive to our plumbing problems. He was great about telling us when he would arrive and worked quickly. We will absolutely use Mark for any plumbing needs in the future.
