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.

AfterFast, Reliable Chimney Sweep Across Palo Alto
A standard chimney sweep in Palo Alto typically runs $189 – $289 for a wood-burning fireplace, and most jobs are completed in 60 – 90 minutes. If you have a vented gas fireplace or direct-vent insert, gas fireplace cleaning runs $129 – $199. We’re Flint Chimney Sweep, part of the Garrison Partners family founded in 2002, and we serve Palo Alto from our San Francisco Bay Area office with background-checked, uniformed technicians. Call (830) 251-4560 for a written price before any work starts.
Palo Alto’s housing stock genuinely complicates chimney work. In Professorville and Crescent Park, you’ll find 1920s and 1930s masonry fireplaces with real flues, aged mortar crowns, and dampers that haven’t been touched in decades. Drive three minutes toward Midtown, and you’re in 1960s Eichler territory where most homes were built without a chimney at all. That split means two different service calls, two different tool sets, and an inspection checklist that changes block to block. We know which checklist applies before the truck arrives, because we ask the right questions on the phone.
Why Flint Chimney Sweep Is Palo Alto’s Preferred Chimney Sweep Company
Palo Alto homeowners keep telling us the same thing about previous chimney companies: the price changed at the door, or the crew never showed. That’s the problem our process removes. Every job gets a written price before any tool comes off the truck. The number you approve is the number on the invoice. Period.
Hank Delano leads our team, and he holds every technician to the same standard we’ve run since 2002: if it’s not done right, we make it right. That’s not a slogan. It’s a written guarantee on every repair, valid for 365 days from the service date. If a covered repair fails within that year, we return and fix it at no charge. No argument, no second invoice.
We also answer the phone. A live person picks up 24 hours a day, 7 days a week. No voicemail trees, no callback forms. When you call about a chimney sweep in Palo Alto, you talk to someone who can schedule the visit and answer your questions that same call.
Gas Fireplace Cleaning in Palo Alto
Gas Fireplace Cleaning in Palo Alto is one of the most common calls we field, and the reason is simple: a large share of homes here don’t have wood-burning flues at all. Eichler homes in Midtown and South Palo Alto were built with radiant heat, and many later added direct-vent gas fireplaces from brands like Gelco. Those units don’t get swept the way a masonry flue does. The work involves removing and cleaning the firebox glass, checking the vent termination outside, cleaning the burner and pilot assembly, and verifying the logs are positioned correctly. A standard gas fireplace cleaning in Palo Alto runs $129 – $199, depending on the unit.
Glass and Burner Service
Build-up on the inside of the glass is the first sign your gas unit needs attention. White film that won’t wipe off is mineral deposit from combustion. Soot streaking on the glass points to burner misalignment or a clogged air shutter. Our techs clean the glass with the right non-abrasive compounds and check the burner ports for blockage before putting everything back.
Vent Termination Check
Direct-vent units pull combustion air from outside and push exhaust out through a side-wall or roof termination. Leaves, spider nests, and even Palo Alto’s damp winter air can clog that termination and cause the unit to shut down. We inspect and clear the termination on every gas fireplace call because a blocked vent is a carbon monoxide risk, not just a performance issue.
Chimney Maintenance in Palo Alto
Chimney Maintenance in Palo Alto means something different depending on which side of El Camino you live on, which is why our Chimney Repair - Palo Alto approach adapts to your home’s specific needs. On the masonry side, maintenance is about water. Winter rain and tree debris from oaks and redwoods in Crescent Park and Professorville land on mortar crowns, soak into spalling brick, and eventually leak into the firebox. A maintenance visit for a masonry chimney focuses on the crown, cap, and flashing, not just the flue. On the gas side, maintenance is about the vent termination and burner condition. The work we do differs, but the price structure doesn’t: you get a written quote before we begin, every time.
Annual Sweep and Inspection
We recommend an annual sweep when you burn wood more than a couple times a month through the winter. For occasional burners, every other year may be enough. The deciding factor isn’t time, it’s the thickness and type of creosote on the flue walls. The inspection tells us which applies to your fireplace, and we’ll give you a straight answer, not a blanket recommendation.
Creosote and Soot Removal
First-degree creosote is a light, flaky deposit that brushes off without much effort. Second-degree is thicker and harder, and third-degree is a tarry glaze that a standard brush won’t remove. When we find third-degree creosote, the job scope changes, and so does the price. That’s why we never quote a flat sweep price before the inspection. We’ll tell you what we found, show you the camera images, and give you the exact cost before any cleaning begins.
Trusted Brands We Service in Palo Alto
We work with professional-grade chimney materials including Chimney Sweep-grade liners and components from Olympia Chimney, Famco, and Copperfield. When a Palo Alto home needs a replacement damper, a new cap, or a flue liner repair, we specify the material by the job, not by what’s cheapest to stock. We don’t maintain inventory in Palo Alto itself, but our Bay Area supply chain means most parts arrive within one to two business days. For repairs on gas units, we service and clean direct-vent systems including Gelco units common in Midtown and Eichler neighborhoods.
Common Chimney Sweep Problems We See in Palo Alto Homes
- Water intrusion through spalling mortar crowns on pre-1960 masonry chimneys. Professorville and Crescent Park have original brick stacks from the 1920s and 1930s. Decades of seasonal rain have worn the mortar crown down, and water gets behind the brick. A sweep removes creosote, but it does nothing for a cracked crown or missing cap. We check both on every masonry call.
- Third-degree creosote glaze in wood-burning fireplaces that get frequent use. Homes near the Stanford campus and in Barron Park burn wood regularly through the winter. When the flue gets hot and cools repeatedly, the creosote hardens into a shiny, tar-like coating. It will not come off with a brush, and it’s a serious chimney fire risk. Camera inspection confirms it, and we adjust the scope and price before cleaning.
- Direct-vent gas fireplaces mistakenly booked as wood-burning sweeps. Eichler homes in Midtown and South Palo Alto have no masonry flue. The fireplace is a sealed gas unit. If we arrive without the right adapters and glass tools, the visit is wasted. We ask what kind of fireplace you have on the phone, and we bring the right equipment the first time.
- Rusted or stuck dampers in older masonry fireplaces. Palo Alto’s damp winter air, combined with a flue that’s left open through summer, corrodes the damper frame. We’ve seen dampers in Professorville that hadn’t moved in 20 years. A damper that won’t seal is an energy leak in winter and a pathway for pests and downdrafts in summer. We free and lubricate them during standard sweeps when possible.

FAQs About Chimney Sweep in Palo Alto
No. If you burn wood fewer than three or four times per winter, an inspection every 24 months is usually sufficient. The question is creosote thickness, not time. Light use produces light buildup, and light buildup rarely becomes a fire hazard inside two years. What changes the answer is moisture, not use. Older masonry chimneys in Professorville and Crescent Park develop cracks and spalling even when you never light a fire, and those need eyes on them annually if there’s been heavy rain. Call (830) 251-4560 and tell us your burn frequency, and we’ll tell you plainly whether this is the year to inspect or whether you can wait.
Look at the firebox. If you see a gas pipe, ceramic logs, and a glass front, you have a gas fireplace. If you see a brick floor, an iron grate, and a metal or steel damper handle above the firebox, you likely have wood-burning. Homes in Midtown and South Palo Alto, especially Eichler builds, are mostly gas. Homes in Crescent Park and Professorville are mostly masonry wood-burning. Still unsure? Call (830) 251-4560 and describe what you see. We’ll tell you what you have and what it costs before we come out.
First-degree is a light, flaky, gray or brown powder that brushes off with a standard sweep. Third-degree is a hard, glossy, tar-like coating that forms when flue temperatures cycle high and low repeatedly. It does not come off with a brush, and it requires chemical treatment or mechanical removal. Yes, it changes the price. A third-degree creosote removal typically adds $150 – $300 to a standard sweep in Palo Alto. We’ll show you the camera image before we quote, so you never take our word for it without seeing it yourself. Call (830) 251-4560 for an exact quote.
Usually, yes. If your chimney has first-degree creosote only, your damper works, and your cap and crown are intact, there’s no urgency. Sweeping in spring is fine. The work cannot wait if you see water stains on the ceiling near the fireplace, smell smoke inside the house after a fire, or your carbon monoxide detector goes off. Those are active problems. A camera inspection will tell you which situation you’re in, and you’ll see the images yourself. Call (830) 251-4560 to schedule an inspection, and we’ll give you an honest answer on timing.
No. We do not offer same-day service. Our Palo Alto sweeps are scheduled, typically within a few business days, and the visit starts with a written price before any work begins. That process takes time, and we won’t compress it to rush a job out the door. If you have an urgent concern, like water actively leaking into the firebox or a carbon monoxide alarm, call (830) 251-4560 and we’ll tell you exactly what to do until we get there, and we’ll prioritize your visit without cutting corners.
