Chimney sweep and repair in Hayward
Postwar tract stock sitting directly on the Hayward Fault’s own trace.

The short answer
Hayward sits directly on the fault that carries its name, and that geology is inseparable from how Nationwide Chimney Sweep & Repair San Francisco approaches a Hayward chimney inspection: the city’s own hall of records famously shows a visible offset in its foundation from decades of slow fault creep, and the U.S. Geological Survey treats the Hayward Fault as one of the most likely in the country to produce a major, damaging earthquake in the coming decades. Most of Hayward’s housing is postwar tract construction built through the 1950s and 1960s as the East Bay’s population boomed, running factory-built fireplace systems rather than older site-built masonry — but on a chimney that predates that boom, the structural connection to the house framing is a genuinely local concern here, not a generic upsell.
Local specifics
What is true about Hayward
- 01
Hayward’s own City Hall and former Hall of Justice building show visible structural offset from decades of slow, continuous ‘fault creep’ along the Hayward Fault, which runs directly beneath parts of the city rather than nearby it.
- 02
The U.S. Geological Survey’s regional earthquake forecasting places a high probability on a major rupture of the Hayward Fault within the coming decades, and the fault’s 1868 rupture — before Hayward’s major postwar growth — was itself a significant, damaging Bay Area earthquake in its own right.
- 03
Cal State East Bay’s hillside campus overlooks Hayward from land close to the fault’s trace, and the surrounding hillside neighborhoods carry a mix of postwar and later construction quite different from the flatland tract housing that makes up most of the city below.
Housing stock
What the housing stock means for the chimney work
The bulk of Hayward’s housing dates from the postwar tract boom of the 1950s and 1960s, concentrated in flatland neighborhoods like Cannery and Fairview, and runs factory-built, metal-flue fireplace systems rather than site-built masonry. Older pockets near downtown and the Mission-Foothill corridor carry earlier-1900s construction with a genuine masonry firebox, and on that older stock specifically, the chimney’s structural tie to the house framing is worth checking directly — Hayward sits on the fault line itself, not simply near a seismic risk described in the abstract.

Jennifer Garcia
Heavy Stage 3 creosote had built up within an inadequately sized flue pipe, but a vigilant technician cleaned it away, preventing catastrophic fire dangers.
Miguel Reynolds
Last winter we got a weird burning smell every time we used the fireplace. They cleaned a thick coating of soft creosote from the higher tiles and the stench is completely gone now.
Leonardo Madden
Most sweepers only glance up with a flashlight. This team established a thorough monitor and pointed out minor gaps in the mortar parging, and brushed the smoke chamber till it appeared brand new.
Rhiannon Wimer
Punctual, polite, and thoroughly professional. They treat your home with total respect and deliver world-class service every single time.
Questions
What people ask about Hayward
Does sitting on the Hayward Fault itself change what an inspection should cover?
On an older masonry chimney, yes — we check the structural connection between the chimney and the house framing specifically, since Hayward sits directly on the fault’s trace rather than simply near it.
Is most Hayward housing masonry or factory-built?
Mostly factory-built — the bulk of the city’s stock is postwar tract construction from the 1950s and 1960s, which runs metal-flue systems. Older pockets near downtown carry genuine masonry fireboxes instead.
Do factory-built systems need the same attention as masonry near a fault?
Less structurally, but they still need the manufacturer-listed cap and a working chase seal — a mismatched part can void the manufacturer’s listing regardless of seismic considerations.
Do you cover all of Hayward, hillside and flatland both?
Yes — Mission-Foothill, Cannery, Fairview, downtown Hayward and every other Hayward neighborhood sits inside our twenty-mile radius from central San Francisco.
