Chimney Repair for Hayward homes
The Hayward Fault runs directly beneath this city, through neighborhoods and under houses, and it is the single most relevant fact about chimneys in Hayward. Unreinforced masonry stacks in the older parts of town, particularly the pre-war housing around downtown and up in the Hayward Highland, have spent decades on ground that moves, and stair-step cracking through mortar joints is something we find here more often than anywhere else we work. Much of the rest of the city is 1950s and 1960s tract housing in Fairway Park, Mount Eden and Southgate, with lighter stacks that are also unbraced above the roofline. Any Hayward inspection we do includes a specific look at whether the stack has shifted relative to the house.
The Hayward Fault runs directly through the city, making seismic assessment central to chimney work here. Pre-war unreinforced masonry near downtown and in the Highland shows stair-step joint cracking more frequently than elsewhere in our area. Extensive 1950s-1960s tract housing with unbraced stacks above the roofline.

Process
How the visit works
Diagnose the cause
Inspection first, including the roof and the flue, so the quote addresses the reason and not just the visible damage.
Scope and quote in writing
What we will do, the materials, the access needed and the price. Free, and yours to compare.
Protect the site
Roof and grounds protected before the work starts, and access arranged so nothing is dropped where it should not be.
Carry out the repair
Repointing, crown rebuilding, liner replacement, flashing, cap fitting or a full rebuild, depending on what the diagnosis found.
Water test and photograph
Where the repair addressed a leak we test it, and you get before and after photographs on completion.
Questions
FAQs
Should I be worried about my chimney because of the Hayward Fault?
It is worth an honest look, particularly if the house predates the war and the stack is unreinforced brick. The part above the roofline is unbraced and is where damage concentrates. Existing cracks or a lean are the signs that matter most.
What is stair-step cracking?
Cracking that follows the mortar joints diagonally in a staircase pattern rather than running straight through the bricks. It indicates the structure has moved, which around here usually means ground movement, and it is a reason to have the flue camera-inspected rather than just the outside looked at.
How do I know whether it needs repointing or rebuilding?
It depends on how deep the failure goes. If the mortar has eroded but the bricks are sound and the stack is straight, repointing is the answer. If bricks are spalling, the stack is leaning, or the structure has moved, rebuilding the affected section is the safer and often cheaper long-term option. The inspection tells us which.
My chimney leaks when it rains. Where is the water coming from?
Usually one of four places: a cracked crown, missing or failed flashing where the chimney meets the roof, porous or unpointed brickwork, or a missing cap letting rain straight down the flue. They present identically inside the house, which is why we diagnose before quoting.
