Water Heater Repair & Installation

It's More Than Cold Showers.

Your water heater is making that banging noise again. Or maybe it's the opposite problem: you turned on the shower and waited. And waited. Nothing but cold water. Here's what most people don't realize. A failing water heater doesn't just mean cold showers. It means a 40 to 80 gallon tank of pressurized water sitting in your garage or closet, rusting from the inside out. When it finally goes, it goes fast. We've seen tanks flood entire first floors in under an hour. The water damage — before you even replace the unit — is significant and fast. Cole's Plumbing has been replacing and repairing water heaters across the DFW metroplex since 2001. We carry the most common tank and tankless units on our trucks, which means same-day installation in most cases. No waiting a week with no hot water. Call before noon and we'll be there today.

What to Expect

How It Works

From your first call to hot water flowing, here's exactly what happens.

We diagnose the real problem

Our service call gets a licensed plumber to your door. We don't guess. We test the heating elements, check the anode rod, inspect the T&P valve, and measure tank sediment. Takes about 30 minutes.

You get options, not a sales pitch

If a minor repair buys you 3 more years, we'll tell you that. If your tank is 12 years old and corroding, we'll recommend replacement and explain why. You decide.

Same-day install when possible

We stock the most popular 40 and 50 gallon tanks plus Rinnai and Navien tankless units on our trucks. Most replacements are done in 2 to 4 hours. We handle the old unit disposal too.

We test everything before we leave

Hot water at every fixture. No leaks at the connections. Gas lines pressure-tested. We don't leave until you have hot water and you're satisfied.

What Homeowners Say

200+ Five-Star Reviews.

Chad came out the same day we called. He looked at our water heater, told us exactly what was wrong, gave us a price, and got it done that afternoon. No surprises on the bill. We've used other plumbers in the area and this was by far the best experience.

Sarah M.Carrollton, TX

The last plumber we called tried to sell us a whole new system when all we needed was a valve replacement. Chad was honest about what the actual problem was and fixed it for a fraction of what the other company quoted. That's rare.

Mike R.Plano, TX

We had a slab leak and were panicking. Chad walked us through the whole process, explained what he was doing at every step, and his price was fair. He even followed up the next week to make sure everything was holding. This is the only plumber we'll call from now on.

Water Heater Repair & Installation FAQ

Straight Answers.

General rule: if your tank is under 8 years old and the problem is a faulty part, repair it. Over 10 years old with a major issue like a leaking tank? Replace it. A corroded tank can't be repaired. We'll show you exactly what we find and let you decide.

Most standard tank replacements take 2 to 4 hours. Tankless conversions take 4 to 6 hours because we need to upgrade the gas line and add venting. We handle everything in one visit.

Depends on your household. A family of 4 or more that runs out of hot water? Tankless pays for itself in 5 to 7 years through energy savings and never running out. A couple in a small home? A quality tank unit is probably the better value.

We quote every water heater installation upfront — the unit, all labor, permits, and old unit disposal are all included. No hidden fees. Call us and we'll give you a clear price before any work starts.

Yes. Call before noon and we can usually install the same day. We carry the most common units on our trucks. If you need something special-ordered, it's typically next business day.
