What Local Customers Say About Williams Plumbing

Diagnose It First

What is your water heater doing

Some of these are a straightforward repair. Some of them mean the unit is near the end. Here is what each one usually points to.

No hot water at all

Could be the thermostat, the element, the pilot or the gas control. Often repairable.

Hot water runs out much faster than it used to

Usually sediment build up inside the tank taking up space that should hold hot water.

Water is pooling around the base of the tank

If the tank itself is leaking it cannot be repaired and it needs replacing. Call now, not later.

Rusty or brown hot water

Often the anode rod or corrosion inside the tank. Worth looking at quickly.

Banging, rumbling or popping sounds

Sediment hardened on the bottom of the tank. Sometimes flushable, sometimes a sign the tank is done.

Pilot light will not stay lit

Commonly the thermocouple or the gas valve. Usually a repair rather than a replacement.

The unit is over 10 years old and acting up

At that age it is worth an honest conversation about repair against replacement before you spend money on it.

The Real Question

Should you repair it or replace it

Here is roughly how we look at it when we are standing in front of your unit.

Repair usually makes sense when:

Replacement usually makes more sense when:

If your unit can be repaired sensibly, we will tell you that, because a customer who was dealt with straight is a customer who calls us again. If it genuinely needs replacing we will explain why and show you what we are looking at.

What We Handle

Water Heater Services

Water Heater Repair

You call or send the form. Tell us what is happening and where you are.

Hot Water Tank Replacement

When the existing tank is no longer practical to repair, discuss replacement options with a plumbing professional.

Water Heater Installation

Professional installation for a new water heating system that fits the home's requirements.

Tankless Water Heater Service

Repair and installation for tankless systems, including sizing advice for your household.

Choosing a System

Tank or tankless

A standard tank.

Lower cost to buy and install, simple to service, and it does the job for most households. It holds a set amount of hot water, so if several people shower back to back you can run it down and wait for it to recover.

Tankless.

Heats water as it flows, so it does not run out, and it takes up far less space. Costs more upfront and the installation is more involved, particularly if the existing venting and gas supply need work. Makes most sense in a busy household or where space is tight.

Tell us how many people are in the house and how the hot water gets used, and we will tell you honestly which one fits. We install both.

The Offer

Free written estimate on replacement, no charge for the visit when you book the repair

You get the full price in writing before anything starts, including taking the old unit away. No extras added at the end and no pressure to decide on the spot.

Financing options available on replacement units, so you are not paying it all at once.
