WarrantyWorkmanship warranty
AvailabilitySame-week visits
HoursMon–Fri 8am–6pm
When a boiler goes out during a Seattle cold snap, waiting a week isn't realistic. We book most repair calls within one to two business days and call 20 to 30 minutes before arrival. On visit day, expect the technician to diagnose the problem first, walk you through the likely cause and cost before starting any work, and complete most single-part repairs the same visit so heat and hot water are back on without a second trip.
Local knowledge
What's different about boiler repair in Seattle
Here is what our techs actually see on Seattle jobs, season after season.
Many Seattle homes in neighborhoods like Ballard, Wallingford, and Beacon Hill still run older cast-iron boilers original to houses built before 1980, and parts for these units sometimes have to be special-ordered.
Seattle City Light serves most homes inside city limits, and older electrical panels can trip when a boiler's circulator pump or igniter draws power during startup, which shows up as a no-heat call.
The Pacific Northwest's long damp season from October through April keeps boilers running nonstop for months, which is exactly when worn gaskets, low pressure, and pressure relief valve failures tend to show up.

How a Seattle boiler repair visit works
1
Call and Same-Day Triage
Call (206) 427-8907 and describe what's happening - no heat, banging, an error code. We give you a rough sense of the likely cause and a two-hour arrival window, usually within 24 to 48 hours.
2
On-Site Diagnosis
The technician checks system pressure, inspects the ignition system, and looks for leaks or corrosion before touching anything, then explains what's actually wrong.
3
Upfront Estimate
You get a written estimate within the $250 to $1,500 range based on the parts your unit actually needs, so there are no surprise add-ons once work starts.
4
Repair and Test
Most repairs - igniters, circulator pumps, zone valves, thermostats - are finished in the same visit. We run a full heating cycle afterward to confirm the boiler holds pressure and temperature.
5
Follow-Up Notes
Before leaving, you get a summary of what was replaced and a heads-up on any part that's aging and likely to need attention next heating season.

Straight answers
Boiler Repair in Seattle — FAQ
How fast can someone get to my house in Seattle for a boiler repair?
Most Seattle calls are scheduled within 24 to 48 hours, and we give a two-hour arrival window with a call ahead of time. No-heat situations during the winter months are prioritized for same-day service when possible.
What's the most common boiler repair in Seattle homes?
A lot of Seattle houses built between 1920 and 1970 still run older gas boilers, so igniter failures, stuck zone valves, and low pressure from small leaks are what we see most often in areas like Ballard and Wallingford.
Do you handle boiler repairs outside Seattle too?
Yes, we cover Seattle along with Bellevue, Redmond, Kirkland, Sammamish, and Issaquah, all from the same scheduling system, so response times across King County stay consistent.
What should I do before the technician arrives?
Clear a path to the boiler closet or utility room, note any error codes showing on the display, and jot down roughly when the problem started. That information helps us diagnose faster once we're on site.
