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.
Fast, Reliable Gas Fireplace Repair Across Palo Alto
Gas fireplace repair in Palo Alto typically runs $180 – $450 for common fixes like thermocouple or thermopile replacement, igniter repair, and burner cleaning, while larger jobs like a chase cover replacement or a full log set swap land in the $600 – $1,400 range. Most repairs in Palo Alto take our team under two hours on site, and we carry common parts for the brands homeowners here actually have, so we’re not sending you back to a showroom in San Jose for a part. When your gas fireplace won’t light, won’t stay lit, or keeps tripping its safety switch, call (336) 863-3889 and talk to a live person who can schedule you, not a voicemail.
If you live off University Avenue, up in the hills, or anywhere between Old Palo Alto and the Stanford border, you’re about 20 to 40 minutes from our Bay Area crews, depending on traffic. We know the houses here because we work on them constantly, and we know which repairs show up again and again in this specific climate. More on that below.
Why Alcott Chimney Sweep Is Palo Alto’s Preferred Gas Fireplace Repair Company
We’ve been servicing gas fireplaces and chimneys since 2002, and the work our Gas Fireplace Repair team does in Palo Alto is a constant part of that. The homes here are not like the newer subdivisions further south. In Old Palo Alto, Professorville, and Crescent Park, we’re working on 1920s Spanish Revivals and Craftsman bungalows where the gas fireplace was retrofitted into a chimney originally built for wood. That retrofit is rarely seamless, and it’s where a lot of nuisance problems start.
Every technician who comes to your Palo Alto home is background-checked and identity-verified under what we call the Threshold Standard. That’s not an optional add-on. You get the technician’s name and photo before the appointment, and they show you a photo ID badge when they arrive. If you’re home alone, or you’ve got young kids, or you just want to know exactly who’s walking through the door, this is how we’ve operated for years. Ruben Castellano set that standard across the company, and it doesn’t change by city.
We also give you a written price before any work starts, and every repair comes with a written guarantee. If a repair we make fails within the coverage period, the second visit is free. It’s our 365-Day Done Right Promise, and it applies whether we’re replacing a thermocouple in a gas log set or rebuilding flashing on a Professorville chimney crown. We’ve always treated Palo Alto customers the same way we treat everyone: straight answers, real dollar figures, no vague assurances.
Our Gas Fireplace Repair Services in Palo Alto
Gas Fireplace and Gas Log Set Diagnosis
Most Palo Alto service calls start the same way: the fireplace won’t light, starts and then shuts off after a minute, or fires up but the flame looks weak and lazy. We diagnose the full ignition sequence from the wall switch or remote to the gas valve, thermopile, pilot assembly, and burner. In Palo Alto homes, especially the older ones near Embarcadero Road and Waverley Street, we often find that a moisture problem higher up the chimney is actually causing the safety switch to trip, not the gas valve itself. We find the actual cause before we touch anything.

Chimney Cap, Crown, and Flashing Replacement
This is the repair we do most often in Palo Alto, and it’s the one most people never see coming. Galvanized chimney caps and standard steel flashing pitted and rusted by bay-area marine-layer moisture fail within a few seasons here. When that happens, water trickles down the flue and lands in the firebox, which trips spill switches and corrodes burners. We replace them with stainless steel caps and copper or stainless flashing that actually holds up in this climate. The difference in material cost is modest; the difference in how long it lasts is years.

Level 2 Camera Inspection of Clay Flue Liners
Palo Alto’s pre-1940s neighborhoods, specifically Old Palo Alto, Professorville, and Crescent Park, carry a hidden legacy from the 1989 Loma Prieta earthquake: offset and cracked clay tile flue liners. These homes passed visual chimney inspections for decades because the damage is inside the flue, not visible from the roof. A Level 2 camera scope shows exactly what’s going on, and we show you the footage. You don’t take our word for it. If the liner is sound, we tell you that plainly. If it isn’t, you see it yourself before any recommendation is made.

Gas Log Set and Burner Replacement
When a gas log set’s burner ports corrode from disuse, or the logs themselves crack from repeated heating and cooling, replacement is often the cleaner fix than repeated patching. We carry and install professional-grade log sets and burners from brands including Famco and Copperfield, which means parts designed for long service life, not a box-store set that needs replacing in three years. For Palo Alto’s Eichler-era homes with decorative fireplaces that have sat dormant for years, this is often the first real service the unit has ever had.

Trusted Brands We Service in Palo Alto
We service and install a focused set of professional trade brands we know well: Famco and Copperfield for gas log sets and components, DuraFlex for flexible liner systems, and HeatShield for flue resurfacing. We keep common repair parts for these brands on our service vehicles, so when we diagnose a Palo Alto fireplace on the first visit, we can usually complete the repair that same visit rather than ordering a part and coming back in two weeks. That matters when you’re using your fireplace on a foggy December evening and it quits.
Common Gas Fireplace Repair Problems We See in Palo Alto Homes
- Rusted-through galvanized chimney caps and chase covers. Palo Alto’s marine layer drives moisture into aging metal components all year round, even when you’re not using the fireplace. Pinhole leaks show up faster here than almost anywhere else in the Bay Area, and by the time you see staining on the ceiling near the fireplace chase, the cap has usually been leaking for months.
- Safety spill switches tripping for no apparent reason. Water tracking down from a failed chase cover or crown lands near the firebox and triggers the spill switch that shuts the unit down. The fireplace doesn’t actually have a gas problem, it has a water problem. We trace the water to its source instead of just replacing the switch and hoping.
- Cracked clay flue tile liners from Loma Prieta damage. Homes in Professorville and Crescent Park that haven’t had a camera inspection since 1989 often show offset liners that restrict draft and create a carbon monoxide risk. This damage is invisible from the outside and won’t show up on a standard visual check.
- Corroded burner ports in seldom-used fireplaces. Eichler-era Palo Alto homes with decorative gas fireplaces often go five or ten years without any service. The gas valve still works, but the burner ports corrode and clog from disuse and coastal moisture, which means the flame pattern is uneven and lazy, and the unit may not stay lit. A burner service or replacement usually resolves it.

FAQs – Gas Fireplace Repair in Palo Alto
Every two years at minimum, and every year if the fireplace is a primary heat source or the chimney is original to a pre-1940s Palo Alto home. The marine layer here corrodes chimney caps, flashing, and gas components faster than drier inland climates, so the standard “once every few years” advice from a national website doesn’t match what we actually see in Old Palo Alto and Crescent Park. Give us a call at (336) 863-3889 and we’ll tell you honestly whether an inspection is due or whether you can safely wait another season.
In our experience across Palo Alto, the most common cause of repeated spill switch trips is moisture reaching the firebox from a failed chimney cap, chase cover, or flashing. The marine layer rusts galvanized chimney components here within a few seasons, and the water that gets through lands where it shouldn’t and trips the safety switch. Fix the water problem first, and the switch usually stops tripping. We’ll scope the flue and show you exactly where the water is getting in before quoting any repair.
A visual inspection looks at what’s visible from the roof and the firebox, but it cannot see inside the flue liner. Professorville and the surrounding pre-1940s Palo Alto neighborhoods have clay tile liners that were never re-inspected after the 1989 Loma Prieta earthquake, and we regularly find offset or cracked tiles on camera that were completely invisible from the outside. A Level 2 camera inspection costs $250 – $400 and gives you footage you can actually look at yourself. Call (336) 863-3889 to schedule one, especially if you’re buying or selling.
Yes, and the reason is specific to Palo Alto. The marine layer and winter fog drive moisture into the chimney structure all year, even when the fireplace sits dormant. That moisture works on the mortar, the damper, the smoke chamber, and the gas burner ports, which corrode from disuse. A fireplace used three times a year doesn’t need aggressive sweeping, but it does need periodic inspection and component service. We’d rather see you once every two years than have you discover a rusted chase cover in escrow.
Yes, it does, and it happens constantly here. In a city where median home prices routinely exceed $3 million, a chimney flagged during inspection can freeze a transaction while buyers and sellers negotiate who pays for repairs. That’s why pre-listing chimney certification has become a near-routine step for Palo Alto realtors. We regularly service gas fireplaces in homes that are about to list, and we provide the written inspection and repair documentation escrow wants to see. If you’re selling, call (336) 863-3889 before the buyer’s inspector does.
