Fit-out specialists
The basics
Get it right the first time
A commercial fit-out sets the tone for your space, your workplace, restaurant, retail shop, office, salon, or hotel, and the plumbing is the part nobody sees until it goes wrong. We handle it end to end: reading your architect or contractor plans, pulling the right permits, running new supply, drain, and gas piping, setting fixtures, and passing inspection. Doing it right the first time means no leaks behind finished walls, no failed inspections, and no costly rework after you open.
What we do
Fit-out plumbing services
Everything your new commercial space needs, from the pipe in the walls to the fixtures on the wall.
Plumbing Rough-In
Supply, drain, waste, and vent piping run to your plans before walls close, the foundation of the whole job.
Fixture Installation
Toilets, sinks, faucets, water heaters, and specialty fixtures set, connected, and tested.
New Piping & Repiping
New water, waste, and gas lines, or replacement of existing piping that will not meet your build.
Plan Review & Permits
We review the plumbing on your plans, pull the permits, and coordinate the inspections for you.
Kitchen & Bar Build-Outs
Food-service plumbing done right: grease traps, gas, pre-rinse, prep sinks, and equipment hookups.
Restroom Build-Outs
New and ADA-compliant restrooms, from rough-in to fixtures, built to code for public use.
How it works
From plans to plumbing
A clear path from blueprint to a space that is ready to open.
1
Review the plans
We study your plans, flag any plumbing issues early, and give you a clear scope and estimate.
2
Permit & schedule
We pull the permits and coordinate with your GC and trades to keep the project on track.
3
Rough-in the piping
We run supply, drain, waste, vent, and gas lines to code before the walls close.
4
Set fixtures & inspect
We install and test fixtures, then handle final inspection so you are cleared to open.
Why it matters
The cost of getting it wrong
Fit-out plumbing is buried in walls and floors. Mistakes are expensive to fix later, so we get it right up front.
Failed inspections
Plumbing that is not to code fails inspection and delays your opening, and your revenue.
Leaks behind finished walls
A rough-in mistake found after drywall and tile means tearing it back open. Get it right the first time.
Undersized or wrong piping
Lines that are too small or wrong for the use cause pressure and drainage problems from day one.
Code and ADA misses
Commercial and ADA requirements are strict. Missing them means rework and liability.
Schedule delays
Plumbing that falls behind holds up every other trade. We coordinate to keep you on track.
Patchwork from multiple plumbers
One crew that owns the whole fit-out avoids the gaps and finger-pointing of piecemeal work.

I had a great experience with Tyler when he came out to replace our toilet flushing system. From start to finish, Tyler was incredibly courteous, professional, and knowledgeable. He walked me through what needed to be fixed, answered all my questions patiently, and completed the job efficiently. It’s rare to find such high-quality service and attention to detail. Everything is working perfectly now, and he left the work area completely clean. I highly recommend Tyler for any plumbing needs!

Absolute best plumbers I have ever used. Needed them a few times recently and each time they were so professional, kind and resolved each problem the first time around. This last issue took them several hours to fix. They explained everything along the way and gave a very fair price for a lot of work. They also work very cleanly! I will never use another plumber! I wanted to add a new review but I could not so I am editing my previous one. I had to use Clarksburg Plumbing again today and like last time, they were exceptional. I was fortunate enough to have John and Madeleine as my service technicians. I will always request them going forward. They are kind, professional and knowledgeable! I am sure the company knows how fortunate they are to have them as part of their team!

We thank Clarksburg Plumbing again for superior, high quality and friendly service! ----- Clarksburg Plumbing visited us last week to repair an external spigot that had been leaking. The work involved creating a little inside access panel. Within and without, a nice, neat job by Charlie and his understudy apprentice, Chris. Problem solved and happy campers here! ----- UPDATE: Plumber John Brown presented himself on time and got right to work replacing my Mom's ancient leaky kitchen faucet with a new store-bought one that I provided. During the process, Mr. Brown detected and showed me two other problem areas contributing to the water leaks: a cracked drain pipe and then rusted threads on the sink trap. He efficiently and expertly repaired all three elements to our full satisfaction. Plus, John is a super nice guy, completely honest and classy enough to laugh at all my corny jokes! The next time you need any plumbing work in your home or business, I strongly endorse John Brown and anyone on the Clarksburg Plumbing team! UPDATE 2: John and his understudy Maddie visited, and quickly solved the problem of a pinhole leak in copper tubing leading from our hot water heater. He advised us on other plumbing needs, for which we have scheduled and will otherwise follow-up. Thank you Clarksburg Plumbing for your top quality people - John Brown in particular - and performance.

Tevon, Noah, Markell, and Morrow were sent by Clarksburg Plumbing LLC to repair an outside broken waterline They arrived at the appointed hour and completed the work in about 3 hours. I was very impressed with them and I would like to recommend all four of these very professional and friendly technicians. Clarksburg Plumbing is a fantastic organization; the office staff, Katie and Charlotte, who helped me are the best.

Thank you to Seth, who came on Wednesday and fixed one of our two toilets and fixed our primary bedroom shower. And thank you to Charlie, who came today and replaced our other toilet and replaced our garbage disposal. You are both lifesavers! Our weekend (and going forward) will be MUCH nicer now that we can use our bathrooms (and garbage disposal) again. Highly recommend Clarksburg Plumbing.

GREAT service and expertise! John and Maddie just installed a water filtration system to our home. The process took one day to install and then they came back from the 48 hour install period to ensure everything was working well. John was familiar and knowledgeable about the water system we bought. Maddie and John kept our space clean, clearly explained how to ensure longevity for our system to last, and the difference it will make in our home. We appreciate their hard work and professionalism. This is our second time using Clarksburg plumbing. We would highly recommend their company to our family and friends.

John Brown was knowledgeable, responsive and pragmatic. He saved us time by diagnosing then recommending best course of action. We are now waiting for the estimate for the project and will be going with Clarksburg Plumbing on our 1948 cap cod renovation. Highly recommend this company’s knowledge, professionalism and responsiveness.

Franklin and his crew showed up promptly and communicated great with us to help limit disruption with the tenants at 4 of our building. Unfortunately for us a second water main leak occurred the day before. But luckily for us they were able to stay on site another 2 days and knock the second one out, even staying till 8pm to find the line and get it repaired. These will be the guys I request for our next time needs

Seth and Brady did a fantastic job replacing our water heater. They were professional, courteous, and detail oriented. They arrived on time and did careful, clean work all the way through. We have worked with Clarksburg Plumbing on smaller items before this and would be very happy to utilize their services in the future, as well.

We were very happy with the service we received today from John and Maddie. They were both very professional, ran the necessary tests to confirm the issue, and explained what they were doing step by step. They wore the protective booties to keep the floor nice and dry from the rainy weather too. Thank John and Maddie for all your help!
