About

At 4M Plumbing, we do things differently — and it starts with our story. We’re a family-owned, locally operated plumbing company rooted right here in San Antonio. Our name, 4M, comes from our founder Bart Morales’s biggest pride: his four children — the “four Ms” who inspired him to build a business grounded in honesty, hard work and treating people right.

Our team brings over 37 years of plumbing experience to every service call, big or small. We opened 4M Plumbing to create a company that combines big-company expertise with affordable pricing and neighborly care. If you’re tired of high-pressure sales, hidden fees or companies who treat you like another job ticket, we’re the team you’ve been looking for.

Our Mission: Plumbing That Puts People First

When plumbing goes wrong, it’s stressful enough — you shouldn’t have to worry about surprise costs or pushy upsells on top of it. Our mission is simple: deliver honest, reliable plumbing services that make your day easier, not harder.

We believe you deserve upfront pricing, licensed professionals who know their craft and solutions that fix the issue the first time. Whether we’re replacing an aging water heater, detecting a hidden slab leak or installing a bathroom plumbing fixture, we do it with integrity and care.

Services Backed By Strong Warranties, Fair Financing And Free Estimates

At 4M Plumbing, we don’t just promise quality work — we back it up. Every service we provide is supported by clear, dependable warranties that protect your investment long after we pack up our tools. We stand behind our repairs and installations because we know you deserve confidence and peace of mind. Our warranty options include:

• 2-year warranty on new installation work
• 1-year warranty on plumbing repairs
• 90-day warranty on drain cleaning services

We also understand that plumbing problems aren’t always planned for in the family budget. That’s why we make it easier with financing options, so you can spread out payments when you need to. On top of that, you’ll get free estimates upfront before we proceed with services. No guesswork, no surprises — just honest pricing you can trust.

Emergency Plumbing When You Need It Most

Plumbing troubles don’t stick to a schedule — and neither do we. At 4M Plumbing, we know a burst pipe, sewer backup or sudden leak can happen anytime, day or night. That’s why we proudly offer emergency plumbing services for homeowners and businesses throughout San Antonio.

Always Standing By Our Core Values

At 4M Plumbing, our work is guided by five core values:

• Transparency — We believe in clear pricing, honest advice and no surprises.
• Affordability — We deliver high-quality work at fair, competitive rates.
• Respect — We treat every home and business like it’s our own.
• Integrity — We stand behind our work and always do what’s right.
• Community — We’re committed to giving back to the city that supports us.

These are the principles we live by, day in and day out.
