Plumbing & gas contractor for Palm Beach County’s oceanfront estates

Builders and owners bring us in from the plumbing design to the final inspection on homes of 5,000 to 30,000 sq. ft. We do it right the first time, and we draw every pipe we run.

01The practice

Not a service company. The plumbing trade on the estate.

Southcoast specializes in plumbing and gas for luxury oceanfront estates and historical renovation projects in Palm Beach County. Our mission is to perform jobs correctly the first time, gaining trust and confidence from our builders and owners.

60+ yrsMendel family experience in Palm Beach plumbing
30,000Square feet, the largest estate homes we plumb
50 storiesHigh-rise experience, multiple towers
Since 2011Mark Timothy, Inc. has used us on every project

After the keys are handed over

We maintain and warranty the homes we complete: backflow certifications, repairs, water heater replacement and defective fixture maintenance. We can also modify existing plumbing at the owner’s request.

02How we run a job

From the architect’s first sheet to the town’s as-built file

  1. 01

    Design assist

    We help architects and engineers with the plumbing design and walk owners and designers through fixture selections.

  2. 02

    Isometric risers

    We draw isometrics for the sanitary, water distribution and gas risers, with value engineering that saves the homeowner money.

  3. 03

    Camera the existing

    On renovations we camera existing conditions first, so nothing hidden in an old house surprises the schedule.

  4. 04

    MEP coordination

    We run the coordination meeting with the builder and trades so everyone knows the piping routes through the ceilings.

  5. 05

    Our own inspections

    A pre-drywall and final checklist is completed before every official inspection, and stays in the project file.

  6. 06

    Red-line as-builts

    Every pipe size and route, water and gas, is red-lined and turned in to the city or town as the project as-built.

From our quality control manual

“Southcoast does all plumbing designs and piping routes on every project we do. We red-line all of our pipe sizing and routes to turn into the city or town building department as project as-builts.”

05The family

Four generations of Palm Beach plumbers, one family office

I started Southcoast in the late 1980s, then closed it in 1998 to work for two very large South Florida plumbing contractors. With what I learned there, I reopened the doors in June 2011.

Every Southcoast employee follows the same written standards in our Quality Control manual, so the work is the same whichever crew is on your project, from a 50-story tower to a historic oceanfront home.

My son Shaun earned his state plumbing contractor certification in 2018 and is our secondary qualifier. My daughter Heather runs the office. Southcoast will stay a family business long after I finish.
