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 Alcott Chimney Sweep Is Broadmoor’s Preferred Gas Fireplace Repair Company
Since 2002, Alcott Chimney Sweep has worked on the same aging masonry throughout Broadmoor that other companies avoid. This neighborhood’s housing stock is remarkably uniform: small single-story and split-level homes built in the late 1940s and early 1950s, nearly all with original brick fireplaces and clay-tile-lined chimneys now exceeding 70 years of service. That uniformity works in your favor. Our technicians have seen the same failure patterns on Amador Avenue, Longview Drive, and the side streets off Broadmoor Avenue dozens of times, so we diagnose faster and with far less guesswork.
We’re part of the Threshold Group family of home-service companies, and every technician who comes to your door is background-checked, identity-verified, uniformed, and announced to you by name and photo before arrival. That’s the Threshold Standard, not an optional upgrade. You’ll know who’s coming before the truck parks on your street. Ruben Castellano leads our team with one rule: show the customer the evidence, explain it in plain English, and put the price in writing before touching anything.
Our Gas Fireplace Repair team serves the entire Broadmoor community from our Los Angeles dispatch office, and we schedule Broadmoor visits with realistic arrival windows so you’re not waiting around all day. We answer our phones around the clock with a live person, which matters when your fireplace smells like burnt plastic at 11 p.m.
Our Gas Fireplace Repair Services in Broadmoor
Gas Fireplace Burner and Log Set Repair
When a Broadmoor homeowner’s gas logs won’t stay lit, the cause is rarely the log set itself. In most Broadmoor homes we service, the original clay flue liner has cracked from decades of marine-layer moisture, and the resulting draft reversal or moisture intrusion is what’s fouling the burner or killing the flame. We repair and replace burners, thermocouples, thermopiles, gas valves, and pilot assemblies, but we always inspect the flue above the firebox. Fixing the burner without checking the liner is like patching a tire that’s still got a nail in it.
Flue Liner Inspection and Remediation
Broadmoor sits squarely in the Pacific fog belt on the western San Mateo Peninsula, which means your chimney masonry stays damp far more days per year than chimneys in Redwood City or San Jose. That persistent wet-dry cycling accelerates mortar joint erosion and clay flue tile cracking. When we find a failed liner, we use HeatShield cast-in-place resurfacing to restore a continuous, insulated flue passage without tearing out your Broadmoor home’s brickwork. This is the same professional-grade material certified chimney professionals specify, and we include camera documentation so you see the before-and-after with your own eyes.
Level 2 Inspection for Fuel Conversion
Converting a wood-burning Broadmoor fireplace to gas, or restoring a gas fireplace that once burned wood, is more involved than swapping log sets. San Mateo County and CAL FIRE require a Level 2 inspection whenever a fireplace changes fuel type, and we perform this inspection to the letter of the code. We evaluate the flue liner condition, smoke chamber, damper operation, firebox refractory panels, and venting path, then document everything with photographs. If the liner is compromised, we tell you plainly and show you the camera footage before any remediation is recommended.
Damper Repair and Replacement
Original 1950s dampers in Broadmoor tract homes often seize open after decades of fog-driven corrosion. An open damper doesn’t just waste heated air; it draws constant marine-layer damp air up the flue year-round, accelerating spalling of the firebox brick and corroding gas burner components even when you never use the fireplace. We replace seized dampers with correct-fit models and verify the seal with a smoke test before we leave.

Trusted Brands We Service in Broadmoor
We service and install gas fireplace equipment from Famco, Copperfield, and Gelco, and we use DuraFlex and HeatShield products for liner work. These are the brands chimney professionals specify, not box-store substitutes. Because we work on so many Broadmoor chimneys with identical original construction, we keep common parts for 1950s-era fireplaces on hand, which shortens turnaround when your burner or damper needs replacing. If your gas log set or insert came with the house and you’re not sure what brand it is, we’ll identify it during the diagnostic visit and source the correct parts rather than adapting something that mostly fits.
Common Gas Fireplace Repair Problems We See in Broadmoor Homes
- Cracked clay flue liner from fog-belt moisture. The heavy marine layer on the western San Mateo Peninsula keeps chimney masonry damp far more days per year than inland communities. That continuous wet-dry cycling opens cracks in the original clay tiles, letting moisture reach the smoke chamber and damper assembly and corroding gas burner components even in fireplaces that are rarely used.
- Creosote dripping onto gas log sets. Many Broadmoor chimneys burned wood for decades before gas logs were installed. Second-degree creosote left behind from those years can soften and drip down when the chimney warms, fouling burner orifices and creating a fire hazard on top of a new gas log set.
- Seized-open 1950s dampers. Original dampers in Broadmoor’s tract homes are now over seven decades old. Many have seized open, drawing constant damp marine air up the flue and accelerating spalling of the firebox brick behind gas inserts. You’ll notice the fireplace holds a draft even when closed, or you hear a rattle when the wind picks up off the ocean.
- Spalling firebox refractory panels. The fog-belt wet-dry cycling that cracks clay liners also destroys the refractory panels lining the firebox. When these panels start crumbling, the firebox loses its heat shield, and the gas log set operates against deteriorating masonry. We replace these with correct-spec refractory panels matched to the original firebox dimensions.

FAQs – Gas Fireplace Repair in Broadmoor
It depends on the scope. Broadmoor is unincorporated San Mateo County, not City of Daly City jurisdiction. Repairs confined to the burner, gas valve, thermocouple, or log set rarely trigger permit requirements. But any repair that touches the firebox structure or flue liner falls under San Mateo County and CAL FIRE permitting authority, which catches many Broadmoor homeowners off guard when they call for what they assume is a simple fix. We tell you during the diagnostic visit whether your repair triggers a permit, and we can advise on the application. Call (336) 863-3889 and we’ll assess your situation honestly.
Often yes, and it’s one of the most common issues we find in Broadmoor’s 1940s and 1950s tract homes. The original clay tile liners were sized and rated for wood-burning temperatures and exhaust. When you switch to a gas log set without verifying the liner’s condition, you risk moisture intrusion from the fog belt corroding the burner, plus potential carbon monoxide issues if the flue is compromised. A Level 2 inspection confirms whether your existing chimney can safely serve the gas appliance. We’ll show you the camera footage and recommend remediation only if the evidence supports it. Call (336) 863-3889 to schedule your inspection.
Annually, and in Broadmoor we mean it more than in most places. The National Fire Protection Association recommends annual inspection for all chimneys, but Broadmoor’s persistent Pacific fog adds a layer of urgency: marine moisture cycles through 70-year-old masonry year-round, not just seasonally. Damage that takes 20 years to develop in Redwood City can appear in half that time along the western San Mateo Peninsula. A yearly inspection catches liner cracks, damper corrosion, and refractory panel spalling before a repair becomes a replacement. Most Broadmoor inspections run $95 to $145. Call (336) 863-3889 to book one: if it’s been more than a year, it’s time.
That smell almost always means creosote is heated and off-gassing somewhere in your Broadmoor chimney, even if you’ve never burned wood yourself. Most Broadmoor chimneys burned wood for decades before gas logs were installed, and the creosote tar left behind can reactivate when the fireplace heats up, producing a sharp, chemical odor. It can also indicate that moisture from the fog belt has saturated old creosote deposits, and that material is now dripping down onto your gas burner. This is a fire hazard and a carbon monoxide concern. Stop using the fireplace and call (336) 863-3889: we’ll inspect, identify the source, and tell you honestly what needs to be done.
Yes, and this is the part most Broadmoor homeowners don’t expect. Your chimney masonry absorbs moisture from the marine layer nearly every morning and evening, then dries during the day. That constant wet-dry cycling cracks clay flue tiles and mortar joints from the inside out, all year round. Once moisture reaches the smoke chamber and damper assembly, it corrodes the damper metal and can rust the gas burner components in an unused fireplace. We regularly find significant flue damage in Broadmoor homes where the fireplace hasn’t been lit in years. The fix starts with an inspection and camera documentation. Call (336) 863-3889.
