Owner · Central Coast Plumber Since 1992
Meet Mark Wallace
I have been in the plumbing work since fifteen, digging ditches. You can say it's in my DNA.
Started my company in 1992 at the ripe age of twenty four. From new residential homes to new commercial buildings, restaurants, remodels, repair, or replace. Anything plumbing related. My goal was to provide for my family in the best and most honest way possible. I'm family-oriented. Having my son helping me after school or on weekends, to now being partners. Our utmost goal is to provide friendly quality service. We are always trying to build our repeat customer fan base. To be known as "Your friendly neighborhood plumber". Someone that won't up-charge or take advantage of your plumbing situation.
I understand plumbing is stressful and inconvenient. Our mission is to make the experience as painless as possible. No job is too small or too large.
Give us a call and let us help you.
