A burst supply line at 2 a.m. A water heater that gives out the morning of a dinner party. A drain that won't clear. A bathroom remodel that needs to come in on schedule. Different problems, same right answer. For 25+ years, Tampa Bay homes and businesses have called Cass Plumbing first — because the first call is the one that decides everything that happens next.
Anyone with a wrench can show up. Not everyone can diagnose a slab leak without opening four floors looking for it. Not everyone can replace a 50-gallon water heater on the same day you called. Not everyone has the licensing, insurance, backflow certifications, and code expertise to handle commercial work without creating a problem worse than the one they were hired to fix.
The cost of a plumbing problem isn't the price on the invoice — it's the price on the invoice plus everything that happens while you're waiting for the right person to arrive. Cass Plumbing exists to compress that timeline. We answer the phone. We dispatch the right tech with the right tools. We diagnose accurately, quote in writing, and fix it the first time. That's the entire product.
We've spent a quarter century building the standard of service Tampa expects from a plumbing company. Six things define how we work — and they apply on every job, from a $200 toilet swap to a $50,000 commercial repipe.
Plumbing emergencies don't keep business hours. Our dispatch line is staffed around the clock — nights, weekends, holidays — by actual people, not bots or voicemail. When you call us at 3 a.m. with water rising in a utility room, a qualified technician is on the way before you finish describing the problem. Every minute of water damage compounds, and we treat every emergency call with the urgency the clock demands.
No diagnostic fees. No mystery charges. Before any work begins, you get a clear, line-item estimate explaining what we found, what we recommend, and what every piece costs. The decision is yours — and it's an informed one.
We don't bill you to show up at your door. You pay only for the work we do — no travel surcharges, no after-hours fees that quietly inflate the invoice, no fine print. The meter doesn't start the moment you pick up the phone.
Quality plumbing isn't a luxury. Find a lower price from a licensed competitor and we'll work with you to make it right.
Parts and labor backed by some of the strongest written guarantees in the trade. If it fails on us, we fix it.
Boot covers, floor protection, complete cleanup. Your space goes back the way we found it — or cleaner.
The cheapest call you ever make is the one to a company that does it right the first time. Here's what's actually different.
From a single dripping faucet to a full commercial repipe, our licensed technicians handle the entire spectrum of residential and commercial plumbing work — using the same hardware, the same protocols, and the same warranties regardless of job size.
Cass Plumbing is the top-recommended plumber for Tampa on Best Plumbers — the nation's leading independent plumbing directory and review platform for licensed plumbing professionals across the United States. The recognition isn't paid for or self-nominated. It's earned through verified customer feedback and consistent service quality, evaluated by an independent third party that exists for one reason: to help homeowners and businesses identify the plumbers actually worth calling.
Same-day plumbing response is only possible when your plumber is already in the area. We staff dedicated local offices in each of the three counties we serve — meaning when you call, you're not waiting for a truck to drive in from somewhere else.
