Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Flint Chimney Sweep Is Hayward’s Preferred Chimney Repair Company
Hayward’s housing stock runs older than most of the East Bay. Many of the brick and stucco chimneys we inspect in the B Street corridor, Tennyson-Alquire, and the hills off Carlos Bee date back to the 1920s through 1950s. Those chimneys have been through decades of seismic settling on the Hayward Fault, and they tell a story in their mortar joints. We know what to look for because we’ve repaired thousands of them.
Every Hayward job runs on Chimney Repair protocols that were built around documentation. You get a written price before work begins, a camera inspection with a photo report you keep, and a 365-Day Done Right Promise in writing. If a covered repair fails within one year, we return at no charge. No argument, no re-quote. Our technicians are background-checked and uniformed, and a live person answers our phone around the clock. That matters when you’re looking at a roof leak on a rainy February night in Hayward.
The crews you’ll see in Hayward are dispatched from our San Francisco Bay Area office, which means we’re not routing anyone in from out of state. We’re in Hayward weekly, and we know which streets near the Hayward Plunge and Weekes Park have the older two-story brick stacks that need crown work after the rainy season.
Chimney Liner Installation in Hayward
Chimney liner installation in Hayward is a repair we recommend most often for homes where seismic hairline cracks in the flue tiles have gone unaddressed for years. A flue liner is the inner channel that carries smoke and combustion gases safely out of the house. When it cracks or erodes, those gases can seep into wall cavities or living space. In Hayward, the combination of earthquake movement and bay fog corrosion means liners in pre-1960 chimneys fail earlier here than in drier inland cities.
A standard chimney liner installation in Hayward runs $1,800 – $2,800 for a typical single-story run, including the new liner, insulation, and top plate. We use DuraFlex stainless liners sized to the appliance and the flue, never one-size-fits-all. Before recommending a liner, we run a camera inspection and show you the footage. If the tiles are intact and only the crown is cracked, we will tell you that and quote the crown repair instead. You should never be pressured into a liner you can’t see evidence for.
HeatShield Resurfacing as a Lower-Cost Alternative
When the original clay tiles have minor spalling but the flue structure is still sound, HeatShield cerfractory resurfacing can restore the liner at about $1,200 – $1,800. It is not right for every Hayward chimney, but it is worth an honest look before we discuss tear-out and replacement.
Signs a Hayward Liner Has Failed
Watch for white staining on the exterior brick near the top of the chimney, a draft that reverses when windows are open, or a sulfur smell after the fire dies. Those often show up after a wet winter, and in Hayward the rain plus fog cycle makes them more common than homeowners expect.
Chimney Flashing Repair in Hayward
Chimney flashing repair in Hayward is one of the most common jobs we book after the first heavy rain of the season. Flashing is the metal seal where the chimney meets the roof, and it fails in two ways here: galvanized flashing from mid-century builds simply corrodes, and the small seismic shifts from the Hayward Fault break the seal even when the metal looks fine. Water then follows the chimney down into the attic and along the firebox wall.
Flashing repair in Hayward typically runs $450 – $950 depending on how many courses of shingles have to be lifted and whether we’re replacing step flashing, counter-flashing, or both. We use copper or heavy-gauge aluminum, not thin box-store material. A written quote comes before any work starts, and the price on the invoice is the price you approved. If you’re seeing water stains on the ceiling near the fireplace or damp brick above the roofline, call (830) 251-4560 to schedule a camera inspection.
Why Hayward Roofs Stress Flashing
Many Hayward homes have shallow roof pitches, and when rain comes off the East Bay hills it hits those low slopes hard. Combined with decades of minor fault movement, that repeated loading works flashing loose faster than in neighboring cities on flatter ground.
Rebuilding vs. Patching
We will patch flashing that has real life left in it, but when the metal is pitted through or the step flashing has pulled free of the mortar line, patching just moves the leak down the stack. A proper rebuild is done once, and it’s covered by the 365-Day Done Right Promise.
Trusted Brands We Service in Hayward
We carry HeatShield and Gelco materials on the trucks we dispatch into Hayward, which means no two-week parts wait for most liner repairs and crown coats. Olympia Chimney caps and dampers are another stock item, because they fail often on older Hayward flues and we’d rather have them on hand. These are professional-grade trade brands, not retail hardware, and we specify them by what the job needs, never by what we make more margin on. You can look up any of them independently.
Common Chimney Repair Problems We See in Hayward Homes
- Seismic hairline cracks in crowns and mortar joints. The Hayward Fault runs through the city, and decades of small movements open gaps you cannot see from the ground. Those cracks let water in, which rusts dampers and erodes flue tiles from the inside out.
- Bay fog and rain corroding chimney caps and spark arrestors. A missing cap lets water soak the brick and rust out the damper assembly, causing spalled brick faces and a damper that will not seal, which then lets carbon monoxide drift into the living space.
- First-degree creosote curing into third-degree glaze. In Hayward’s rarely used fireplaces, light creosote deposits sit through damp winters and harden into a tar-like glaze that is far more expensive to remove and raises chimney-fire risk.
- Spalling brick on pre-1940 stacks. Brick from older Hayward buildings absorbs more water than modern units, and repeated wet-dry cycles in fog and rain cause the faces to pop off. We repoint and rebuild these stacks regularly along B Street and in the flats near Tennyson.
Pricing for Chimney Repair in Hayward, CA
Here are the ranges Hayward homeowners should expect. A standard mortar repointing job runs $500 – $1,200. Crown repair or rebuild: $350 – $800. Chimney cap replacement with a stainless unit: $180 – $400 installed. Flashing repair: $450 – $950. Full flue relining with DuraFlex: $1,800 – $2,800. HeatShield resurfacing: $1,200 – $1,800. A Level 2 camera inspection, which most insurance-claim and real-estate situations require, runs $249 – $399.
What moves the number is access and condition. A two-story stack on a steep gable costs more in labor than a single-story on a shallow pitch. Badly spalled brick costs more than clean mortar joints. We never quote blind over the phone for repair work, because the honest price depends on what the camera shows. The estimate is free, and it includes the written quote before any work starts.

FAQs About Chimney Repair in Hayward
Once a year is the honest answer, and in Hayward it matters more because of the seismic settling. The Hayward Fault’s small movements open hairline cracks that would not appear on a chimney in a geologically quieter city, and those cracks are exactly what an inspection catches before a liner or crown fails. If you burn more than two cords a season, inspect every year. If you burn rarely, every other year is usually acceptable, but after any significant earthquake with a Hayward epicenter, schedule a Level 2 inspection even if everything looks fine. Call (830) 251-4560 to book one.
Most Hayward repairs fall between $350 and $2,800, and the inspection that tells you what you actually need costs $249 – $399 for a Level 2 camera scope. The estimate is free, and that estimate includes the written quote before any work begins. We won’t charge you one price and then add “necessary” work at the door. Call (830) 251-4560 for an exact figure on your chimney.
Often we can fix just the crown and flashing, and in Hayward that is true for a large share of the homes we visit. The flue liner only needs replacement when the camera shows cracked tiles, eroded mortar joints between tiles, or gaps that let combustion gases escape the flue. We show you the footage and explain what you’re seeing. If the liner is sound, we say so, and the crown and flashing repair is what gets quoted. No upsell, no pressure. Call (830) 251-4560 and we’ll show you the camera view ourselves.
Third-degree creosote is a hardened, tar-like glaze that forms when lighter creosote deposits sit through repeated wet and dry cycles, which Hayward’s damp winters and foggy springs encourage. It is the most difficult stage to remove and the most likely to fuel a chimney fire. The way to avoid it is annual sweeping before the deposits cure, especially in Hayward fireplaces that see only occasional use. If you suspect a heavy glaze, call (830) 251-4560 for a sweep and inspection before you light another fire.
We do not promise same-day service, because a proper repair requires a camera inspection, a written quote, and the correct materials on the truck before we start cutting into your roof or crown. What we do offer is scheduling inside a firm window, a live person on the phone around the clock, and repair work completed on the first visit once the scope is agreed. In Hayward’s rainy season, we prioritize active leaks. Call (830) 251-4560 and we’ll get you on the schedule.
What a Hayward Chimney Repair Actually Looks Like
Hayward sits on the Hayward Fault, so decades of minor seismic shifting have left many early-1900s stucco and brick homes with hairline cracks in the chimney crown and mortar joints that let water into the flue. That is a repair need driven by earthquake wear, not just fire wear, and it changes how we approach almost every Hayward chimney. We look for the crack pattern that says “fault movement” rather than “age,” because the fix is different: you stabilize the crown and repoint the joints, then seal the cap, rather than simply cleaning and patching.
We got a call from a homeowner near Hayward’s B Street corridor who’d noticed brick flakes on the roof after a rainstorm. Our tech found a cracked chimney crown and spalling mortar at the top of the stack, and water had been running down into the firebox. We rebuilt the crown, repointed the spalled joints, and installed a new stainless chimney cap to keep out the rain and the birds. A follow-up Level 2 inspection with our camera confirmed the flue liner was dry and intact. Job done, no surprises.
That is the standard we run on every Hayward job: written price first, camera evidence in your hands, and a guarantee in writing. Hank Delano set the expectation that every homeowner should know exactly what is being done to their chimney and why, and that standard applies from the first phone call to the final photo report.
