Plumber in Olympia, WA
Home Comfort Alliance’s licensed plumbers fix leaks, clear drains, replace water heaters and update fixtures in Olympia homes. Jobs are dispatched from our Sumner branch, and every repair starts the same way: we find the cause, then give you a written price before any work begins.
Olympia sits at the southern tip of Puget Sound, where winters are wet and mostly mild but can turn sharply cold. Cold snaps like that are when exposed pipes in crawlspaces and on exterior walls split. The city has also been shaken by strong earthquakes, most recently the 2001 Nisqually quake, which is why water heater straps and flexible gas connectors matter here.

Common plumbing calls in Olympia homes
- Frozen or split pipes after a hard freeze, most often in crawlspaces, garages and hose bibs on the north side of the house.
- Slow or backed-up drains from grease, roots in older clay or cast-iron lines, or a sagging section of sewer pipe.
- Water heaters at the end of their life, usually showing as rusty water, rumbling, or a slow leak at the base.
- Running toilets and dripping faucets that quietly raise the water bill.
- Galvanized supply pipe in older homes near downtown and on the east and west sides, which narrows with rust and drops water pressure over time.
- Low water pressure from a failing pressure regulator or a partly closed main valve.
When a plumbing problem can’t wait
Shut off the main water valve and call us if water is spreading and you can’t stop it at a fixture valve, a pipe has burst, sewage is backing up into a tub or floor drain, or you smell gas near a water heater. For a gas smell, leave the house first and call 911 and PSE from outside. Knowing where your main shutoff is before you need it saves the most damage; our plumbers will show you on any visit.
Water heaters: repair, replacement and heat pump models
Most tank water heaters last around 10 to 15 years. When yours is near the end, we price three paths side by side: a like-for-like gas or electric tank, a tankless gas unit for continuous hot water, or a heat pump water heater, which uses far less electricity than a standard electric tank.
- PSE rebate: a qualifying heat pump water heater installed on or after January 1, 2026 can earn a $1,000 PSE rebate, or $1,100 with Efficiency Boost (PSE heat pump water heater rebate). Home Comfort Alliance is a PSE Trade Ally approved contractor for water heaters.
- Earthquake straps: every water heater we install is strapped to the wall and connected with flexible lines, which matters in a city with Olympia’s earthquake history.
- Permits: the City of Olympia requires a permit for water heater work (City of Olympia, What Do I Need?), and we pull it.
Sump pumps and wet crawlspaces
With as much rain as Olympia gets, crawlspaces and basements on low or poorly drained lots can collect water through the winter. A sump pump moves that water out before it soaks insulation, rusts ductwork or rots floor framing. We install new pumps, replace failed ones, add check valves so water doesn’t flow back into the pit, and can add a high-water alarm so you hear about a problem before the crawlspace floods. Pumps that run constantly or cycle every few minutes usually point to a failed float switch or a missing check valve, both simple repairs. More on our sump pump page.
Fixtures, repiping and remodel plumbing
We replace faucets, toilets, shower valves, garbage disposals and hose bibs, and we repipe homes when old galvanized or failing lines make spot repairs a losing game. For a remodel, we rough in new supply and drain lines and set fixtures once the finishes are done. Anything that changes the plumbing layout is permitted through the City of Olympia inside city limits, or Thurston County outside them.
Hose bibs, crawlspace lines and freeze protection
Outdoor faucets are the first thing to fail in a freeze. A standard hose bib holds water right at the wall, so a hose left connected on a cold night can split the pipe inside the house, and the leak often isn’t noticed until the next time the faucet is turned on in spring. We replace old bibs with frost-free models that shut off inside the heated wall, add insulation to exposed crawlspace lines, and fit shutoff valves so outdoor lines can be drained for winter. See our hose bib replacement page for more detail.
If a pipe has already frozen, don’t use an open flame on it. Open the faucet it feeds, warm the pipe gently with a hair dryer or space heater kept clear of anything flammable, and call us if you see bulging, frost that won’t melt, or water where it shouldn’t be.

Olympia plumbing FAQ
How much does a plumber cost in Olympia?
Our plumbing dispatch fee is $99, and the plumber quotes any repair on site before work begins. Drain cleaning is $148 (the dispatch fee is charged separately) and a standard water heater flush is $230, or $150 when added to a furnace, AC or heat pump tune-up (prices as of November 2026). For comparison: Seattle-area data puts a typical plumbing repair between $284 and $760, with most around $522, and hourly rates of $150 to $200 (Angi, July 2026). We give a written price after diagnosing the problem.
Do I need a permit for a water heater in Olympia?
Yes. The City of Olympia requires permits for water heater and gas appliance work. We pull the permit and meet the inspector.
How do I keep pipes from freezing in Olympia?
Insulate pipes in crawlspaces and garages, disconnect hoses and cover hose bibs before the first freeze, keep the heat on when you travel, and let a faucet drip on the coldest nights. Olympia’s record low is minus 8°F, so hard freezes do happen.
Is there a rebate for a heat pump water heater in Olympia?
Yes. PSE offers $1,000, or $1,100 with Efficiency Boost, for a qualifying heat pump water heater installed on or after January 1, 2026. Home Comfort Alliance is a PSE Trade Ally approved contractor for water heaters.
Do you serve Lacey and Tumwater too?
Yes. Our Sumner branch covers Olympia, Lacey, Tumwater and nearby Thurston County addresses.
Should I repipe a house with galvanized pipe?
If the house still has galvanized supply lines and you are seeing low pressure, rusty water or repeated leaks, repiping with PEX or copper usually costs less over time than chasing individual leaks. We inspect the lines and give you a written repipe price alongside repair options so you can choose.
What warranty comes with your work?
We support the manufacturer’s warranty on covered equipment parts, and our labor warranty covers installations for 1 year from installation. Home Comfort Club members (monthly membership starting at $15 a month) with a new system installed by Home Comfort Alliance get extended labor coverage for as long as their membership stays active, up to 5 years from installation.
