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 Los Altos Hills’s Preferred Chimney Repair Company
Los Altos Hills homeowners rarely have a simple chimney. Homes here sit on one-to-two-acre parcels with mature valley oaks and redwoods pressing close to the roof, and that greenery creates problems most city chimneys never see: leaf litter, rodent nesting, and sustained moisture against brick and mortar. We know the neighborhoods, from the winding drives off Stonebrook Court to the ridgeline properties near the Los Altos Hills Golf & Country Club, and we schedule accordingly. Crews reach Los Altos Hills from our San Francisco Bay Area office, and every technician arrives in uniform, background-checked, and holding a camera, not a clipboard of vague recommendations.
Hank Delano has built the repair side of this business on a simple rule: no work gets quoted without camera evidence. You see the cracked flue tile. You see the spalling brick face. You see the exact joint that’s failed. When you approve a repair, the number on the written estimate is the number on the invoice. That’s the Garrison Standard, and it applies to every job in Los Altos Hills, no exceptions.
Chimney Crown Repair in Los Altos Hills
Chimney Crown Repair is the most common repair we quote on hillside properties in Los Altos Hills, because the chimney crown, the concrete cap at the very top of the chimney, takes the full force of every freeze-thaw cycle and every wet-season rain from November through March. When a crown cracks or separates, water seeps into the brick below, and that’s where the real damage starts. In Los Altos Hills, a cracked crown on an exposed hillside chimney typically runs $850 to $2,600 to repair, depending on whether we’re resurfacing the crown or rebuilding the top courses of brick beneath it.
When the Crown Can Wait
Not every cracked crown needs immediate attention. If the crack is hairline, the damage is cosmetic, and we can document that with photos, we’ll tell you plainly: this can wait until spring, and here’s what to watch for. But if water has been tracking through the crown into the flue or firebox, that’s not a wait-and-see situation. The one-year guarantee applies to crown work whether we do it in August or February.
What Crown Repair Actually Involves
We don’t patch over a failing crown and call it done. The old surface comes off, we build up proper slope and drip edge so water sheds away from the flue, and we use a crown-specific sealant that flexes with temperature swings. In Los Altos Hills, where ridge lines expose chimneys to temperature shifts of twenty-plus degrees in a day, that flex matters.
Chimney Repair Companies in Los Altos Hills
If you’re comparing Chimney Repair Companies serving Los Altos Hills, the differences come down to two things: what they document, and what they guarantee. We put a written price in your hands before any tool comes off the truck. We inspect with a camera and hand you the photos, not a verbal description. And every repair carries a 365-day guarantee in writing. Mortar repointing on a typical Los Altos Hills chimney runs $1,200 to $3,000, and tuckpointing, which is repointing done to match decorative mortar joint profiles, runs $450 to $900 for a partial chimney face. Flashing repair at the roofline runs $500 to $1,800 depending on whether we’re patching or replacing the flashing and counter-flashing on a steep, wooded-lot roofline.
How We Quote Repairs
The price you approve is the price you pay. We don’t arrive with an estimate and discover, oh, a whole extra liner issue once we start. The camera inspection happens first, you review the photos with our technician, and then you get a written estimate with the scope specified line by line. If something changes mid-repair, we stop and put the change in writing before proceeding.
What the One-Year Guarantee Covers
If a covered repair fails within 365 days of service, we return and fix it at no charge. No argument, no re-bid, no fine print about the chimney’s age or the weather. That’s the Done Right Promise, and it’s included on every repair we do in Los Altos Hills, from crown resurfacing to full chimney rebuilding.
Trusted Brands We Service in Los Altos Hills
We stock and install professional-grade chimney materials, not whatever’s cheapest at the supply house. When a Los Altos Hills chimney needs a new cap or a damper repair, we use Olympia Chimney and Famco hardware. When flue relining is called for, we specify DuraFlex liners sized to the existing masonry, not the other way around. Keeping local stock for Los Altos Hills means most common hardware replacements happen in a single visit, not a week after a part ships from somewhere else.
Common Chimney Repair Problems We See in Los Altos Hills Homes
- Debris and animal nesting in flues. Wooded parcels off El Monte Road and Page Mill Road produce constant leaf litter, and valley oaks are essentially squirrel apartment buildings. A blocked flue shows up as poor draft or a musty smell near the firebox long before any creosote becomes an issue.
- Spalling brick and cracked crowns from freeze-thaw cycling. Chimneys on exposed hillsides go through more wet-dry and freeze-thaw cycles than valley homes, and the brick face pays for it. Once a brick face starts spalling, water enters the structure and accelerates everything else.
- Flashing failures at steep rooflines. The intersection of chimney and roof on a heavily wooded Los Altos Hills lot is where water likes to travel. Failed flashing lets moisture track down into the smoke chamber and present as a draft problem, not a leak.
- Rodent and bird nests behind dampers. Even chimneys that have never had a fire get used as housing. We routinely pull nests out of flues on homes where the fireplace has been decorative for a decade.

Mortar repointing runs $1,200 to $3,000 for a full chimney face, and tuckpointing runs $450 to $900 for partial sections.

We were called to a home off Stonebrook Court where the owner noticed a faint musty smell near the firebox even though the fireplace had sat cold all season. Our tech ran a camera up the flue liner and found a squirrel nest and a loose mortar joint behind the smoke chamber, not a creosote problem at all. We pulled the nest, re-seated the damper, and documented the joint with photos before quoting a crown repair. The owner approved a flat price before we scheduled the follow-up, and we told them the crown work could wait until the rains actually arrived.

FAQs About Chimney Repair in Los Altos Hills
In Los Altos Hills, annual is the honest answer, not because of creosote buildup but because of debris. The large, heavily wooded parcels with mature valley oaks and redwoods mean leaf litter, twigs, and rodent nesting find their way into flues regardless of how often you burn. We recommend a Level 1 inspection once a year, even for fireplaces that sit cold, because blockages on these lots show up independent of use. If the camera shows a clean flue, we’ll tell you plainly and won’t sell you a sweep, but don’t skip the inspection just because you don’t burn. Call (830) 251-4560 to book, and we’ll put the price in writing before the visit.
First-degree creosote is a light, dusty soot that brushes off easily with a standard sweep. Third-degree, or glaze, is a hard, shiny, tar-like coating that forms when a chimney burns through serious temperature cycles, and it requires rotary cleaning heads or chemical treatment to remove, which costs more. In Los Altos Hills, our techs see less glaze than homes in colder climates because burn seasons here are shorter and fires are often occasional. The camera inspection tells you which condition your flue actually has before you pay for anything. Call (830) 251-4560 and we’ll explain exactly what we find with the photos in front of you.
Sometimes, yes. If a crown crack is hairline and not letting water through, or if flashing has a minor gap that hasn’t yet caused moisture intrusion into the smoke chamber, we’ll say so and document it with photos, and we’ll tell you what to watch for. But if water has already been tracking into the flue or firebox, waiting risks structural damage that turns an $850 crown repair into a $3,000 rebuild. The camera tells the truth either way. Call (830) 251-4560 for an inspection, and we’ll tell you honestly what can wait and what can’t.
Yes, every inspection and every repair quote includes a camera run up the flue, and the photos are yours to keep. You see the crack, the nest, the spalled brick, the missing mortar joint, whatever it is. We don’t ask you to take our word for it. In Los Altos Hills, where homeowners are rightly skeptical of being told they need thousands of dollars of liner or masonry work they can’t verify, the camera is the difference. You get the report, and the written quote matches what the photos show. Call (830) 251-4560 to schedule.
No, and no reputable shop should promise it. A proper repair starts with a camera inspection, then a written quote, then you decide. We schedule Los Altos Hills repairs on a normal booking window, not a same-day rush, because the jobs involve masonry work that cannot be done well in an afternoon. What we do offer is a live person on the phone 24/7, a booked appointment window we hit, and a written price before any work starts. Call (830) 251-4560 for a free estimate, and we’ll give you a straight answer on timing.
