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.

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 needed a water valve installed for my new fridge and a new faucet installed in upstairs bathroom. Seth was amazing. He came out and really listened to me and my concerns. We even called the company that was going to deliver my new fridge so he would have a better understanding of what he needed to do his job. It made me feel at ease with the whole process. He is even coming back later in the week to install new fridge once it’s delivered. I will absolutely call them again.

Seth replaced our hose bib in the front yard and did a great job! It was hot out but he still took the time to make sure everything was good to go. I called Clarksburg Plumbing yesterday and they were able to come out next day. Very professional.

Amazing experience with Clarksburg Plumbing LLC! Our well pump needed replacement. Seth showed up right on time, was very professional, knew what he was doing and pricing was fare (they showed me all estimates upfront and explained everything). Any future plumbing needs and Clarksburg Plumbing will be my first call. I’ll also ask for Seth by name if I can get him!!

We had a pinhole leak suddenly appear in our outdoor hose bib, and Clarksburg Plumbing was able to provide next-day service, which we really appreciated. Our technician, John Brown, arrived right on time after giving us a 30-minute courtesy call. John quickly diagnosed the problem, explained everything clearly, and provided an accurate assessment of what needed to be done. He completed the repair in under two hours, and the quality of his work was excellent. Before leaving, he even took the time to share some helpful tips on how to prevent similar issues in the future. John was friendly, professional, knowledgeable, and efficient from start to finish. We couldn’t have asked for a better service experience. I highly recommend Clarksburg Plumbing and especially John Brown for anyone needing reliable, high-quality plumbing work.

Clarksburg Plumbing installed an external bib; after a couple of months there was a mechanical failure in the vacuum breaker. They responded within 24 hours, fixed it, no charge. Seth was prompt, courteous and efficient. We will be happy to use their services again.

Cris and Franklin from Clarksburg Plumbing did incredible work at our home fixing an underground water service leak. They encountered complications but went to plan B efficiently and skillfully and got the job done well and in a timely manner. They also answered all our questions patiently and taught us a lot of why they made the decisions they made. We are very pleased with their work and plan to recommend them and all of Clarksburg Plumbing to our friends and neighbors.

We had a clog in our septic line. The Clarksburg Plumbing crew located the troublesome area using a camera and then removed the clog and tested the line. They then remounted the toilet with a new wax ring and cleaned the area. Overall, a great experience!

Seth was absolutely amazing! He was very courteous and knowledgeable about his profession. He arrived on time and worked the entire time. He kept me in the loop the entire way as to what he was doing. He diagnosed two leaks within our toilet system and readily fixed them. Clarksburg Plumbing should be honored to have such an amazing employee as him.
