Water Heater Repair & Installation in Friendswood, TX
Tank, tankless, gas, or electric — our licensed team stocks Rheem, Bradford White, A.O. Smith, Rinnai, and Navien parts on the truck. Most repairs done in one visit.
Friendswood's hard water is brutal on water heaters. Our tap water runs 12–15 grains per gallon of hardness on average, which cakes calcium onto burner shrouds, coats heating elements, and cuts the lifespan of an unmaintained tank down from 12 years to about 8. When your unit finally starts making popping noises, running lukewarm, or leaking around the base, we can be in your utility closet the same day with the right replacement in the truck.
We've installed and serviced water heaters in every neighborhood from Autumn Creek and Falcon Ridge to the older ranch homes along Bay Area Boulevard. Whether you want to stay with a traditional tank or upgrade to a tankless system that handles Gulf Coast humidity and busy family demand, we'll walk you through the trade-offs honestly — no scare tactics.
Signs your Friendswood water heater needs service
- No hot water, or hot water that runs out in 5 minutes
- Rust-colored or metallic-tasting hot water
- Popping, rumbling, or hissing sounds from the tank (that's scale)
- Puddle of water around the base or the drain pan
- Pilot light won't stay lit on a gas unit
- Tripped high-limit switch on an electric unit
- Water heater is 10+ years old (average Friendswood lifespan is 8–12)
- Rotten-egg smell in hot water — usually a failed anode rod reacting with hard water
- Error codes flashing on a tankless unit

Our Process
The same steps on every job — from a $189 drain clear to a $9,000 whole-house repipe.
- 1
Diagnosis
We test element resistance, gas pressure, thermocouple, thermostat, and T&P valve to identify the true failure — not just guess.
- 2
Repair-vs-Replace
We give you the honest math. A 9-year-old tank with a bad element and rusted base is usually a replacement conversation, not a repair.
- 3
Flat-Rate Quote
Written pricing on repair or on 2–3 replacement options (tank sizes, tankless upgrade) before we start.
- 4
Install & Permit
Texas requires permits for water heater replacements. We pull them, schedule inspection, and handle it start to finish.
- 5
Test & Cleanup
Full leak test, pressure test, hot-water verification at the farthest fixture, and haul-off of your old unit.
Your Water Heaters Appointment, Step by Step
Before we arrive
A licensed dispatcher confirms your address, describes what our tech will do first, and gives you a firm arrival window. For emergencies inside 77546 we hold a 45-minute promise; scheduled water heaters visits get a 2-hour window.
On the truck
Your assigned Master Plumber arrives in a branded vehicle stocked with common water heaters parts — Delta, Moen, Kohler, Rheem, Bradford White, Uponor PEX-A — so most jobs finish in one visit without a supply-house trip.
Before work starts
You get a written flat-rate price in your hand covering labor, materials, permits (when required by the City of Friendswood), warranty terms, and cleanup responsibility. You approve in writing before we lift a wrench.
What We Service
What Affects Your Price
We don't publish fake prices to trick you into calling. We do publish the honest factors that drive real cost — so when we hand you a written quote, you know why.
Size and fuel
A 40-gal electric replacement is different pricing than a 75-gal power-vent gas unit. Bigger family, bigger heater.
Tankless conversion
Converting to tankless adds gas-line upsize, venting, and often a dedicated 120V outlet. We show the true installed cost, not just the box price.
Code upgrades
Older Friendswood installs may need an expansion tank, a proper drain pan with a drain line, or a T&P discharge extension to meet current TX plumbing code.
Access
Attic installs (very common in Pearland and Friendswood) add ladder time and safety measures compared to a garage swap.
Why This Matters in Friendswood, TX
The Clear Creek watershed sits on limestone-heavy aquifer sources, which is why homes across Friendswood, Pearland, and Alvin all get slammed with hard water. We routinely pull water heaters that are only 6 years old but have 4 inches of calcium sludge in the bottom of the tank — enough to shorten the life of a $1,600 unit by half. If we're installing a new heater in your home, we'll also tell you honestly whether a whole-house softener would pay for itself.

Frequently Asked
How long does a water heater last in Friendswood?
Because of hard water, expect 8–12 years for a standard tank and 15–20 for a well-maintained tankless. Annual flushing can add 2–4 years to either.
Do I need a permit to replace my water heater in Texas?
Yes. The state and City of Friendswood both require a permit for water heater replacement. We pull the permit and coordinate inspection as part of every install.
Is tankless worth it for my Friendswood home?
For homes of 3+ people or with big bathtubs, usually yes — you get endless hot water and 20–35% lower gas bills. For a couple in a 1,500 sqft home, a good tank is often the better value. We'll run the numbers with you.
Why is there a rotten-egg smell in my hot water?
Almost always a chemical reaction between the magnesium anode rod and sulfur bacteria in local hard water. Swapping to an aluminum-zinc anode usually solves it same day.
Can you install a heater in my attic?
Yes — most Friendswood homes have attic-mount units. Texas code requires a drain pan with a piped drain, and we always include that.
