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.

AfterFireplace Services in Martinez: What It Costs and What We Actually Find
Fireplace service in Martinez, CA typically runs $189-$289 for a standard inspection and cleaning, $340-$680 for damper repair or replacement, and $2,400-$5,800 for a full fireplace insert installation. Those are the numbers we quote most often here, and they’re written down before any work starts. If you live in the historic core near downtown or up in the hills off Alhambra Valley Road, you’re dealing with conditions most other Bay Area cities never see: Carquinez Strait downdrafts, refinery sulfur fallout, and 80-to-120-year-old flues that need more than a quick sweep. Call (980) 580-8641 and we’ll give you a written price before we touch anything.
What makes Martinez different from Concord or Pleasant Hill isn’t subtle. It’s the wind. The Carquinez Strait funnels the Delta breeze through this city with enough force to push smoke and carbon monoxide backward into living rooms, even when the flue is clean and the damper is wide open. We deal with that every week. It’s why wind-directional caps are a near-standard recommendation here, not an upsell.
But the bigger issue in Martinez’s older neighborhoods is shared flues. Many of the Craftsman and Victorian homes radiating out from downtown along Alhambra Avenue and Escobar Street were built with a single brick chimney stack serving two or even three fireplaces. When a neighbor’s gas appliance vents into that common stack, their combustion byproducts can get pulled into your wood-burning fireplace. That’s not a draft problem. That’s a contamination problem. And it’s the single most common reason we get called to this part of Contra Costa County.

Why Emberly Chimney Cleaners Handles More Martinez Fireplace Calls Than You’d Expect
Our crews are in Martinez most days of the week. The service area covers everything from the waterfront condos near Marina Vista to the mid-century ranch homes up in the hills behind Hidden Lakes Park. Dispatch is coordinated from the brand’s San Francisco Bay Area office, but the techs who show up know Martinez’s housing stock cold, because they’re here constantly.
We’ve been running camera-scan inspections as our default since 2009, long before any regulator or insurer asked for it. That’s Clause 4 of the Haven Standard: a documented photo record on every single visit, no exceptions. You see what we see. If we tell you a flue liner is cracked, you get photos of the crack. If we tell you the crown is spalled, you get photos of the spalling. We don’t ask you to take our word for anything.
Every quote is written before work starts, with the scope and the warranty in writing. That’s Haven Standard Clause 1. You don’t pay for a flashlight look and a vague warning. You get a named tech, a text when they’re on the way, and a written record when it’s done. Corrine Halstead runs our team, and she’s the one who makes sure that standard hasn’t slipped once since 2009, across more than 38,000 inspections and cleanings.
Our Fireplace Services in Martinez
Here’s what we actually do in Martinez, week in and week out. If you need something that isn’t here, call (980) 580-8641 and ask. If we don’t do it, we’ll tell you who does.
Damper Repair
Dampers in Martinez fail in two predictable ways. First, the marine moisture off the strait keeps the metal damp longer than it would inland, so throat dampers rust and seize. Second, wind-driven pressure cycles wear out the pivot hardware on older cast-iron dampers. We replace rusted or warped dampers with top-sealing models that can stop the downdraft problem at the top of the flue, which addresses both issues at once. If yours is sticking, don’t force it - a snapped damper cable is a $180 add-on that would have been a $0 inspection note.
Fireplace Conversion
Converting a wood-burning fireplace to gas in Martinez usually means dealing with a flue that hasn’t been properly maintained in decades, plus the wind problem. We handle the full conversion: gas line, log set or insert, and the flue liner work that keeps your neighbor’s exhaust out of your house on a shared stack. Most conversions here run $3,200-$6,800 depending on whether you want a vented log set or a sealed direct-vent insert. We’ll quote the exact number in writing before we start.
Gas Fireplace Service
Gas fireplaces in Martinez don’t escape the downdraft issue. A wind-driven reversal in a vented gas log setup can push carbon monoxide into the room, and without a working CO detector near the fireplace, you won’t know it’s happening. We service gas valves, pilots, thermocouples, and venting, and we always check the termination cap for corrosion from strait moisture. If you’ve got a gas fireplace that’s been running “fine” for years, but you smell something faint and acrid when the wind picks up off the water, get it checked. That’s not normal.
Wood Burning Fireplace
Wood burning in Martinez produces a creosote profile we don’t see in Lafayette or Walnut Creek. Airborne sulfur compounds from the refinery on the western edge of town settle on flue walls and bind with standard wood-smoke creosote, forming a chemically aggressive glaze that’s harder to remove and more corrosive to terra cotta liners. We see liners that looked fine five years ago showing chemical etching that has nothing to do with how often you burn. That sulfur residue also reacts differently with cleaning agents, which is why we don’t use off-the-shelf chemical treatments on Martinez flues without knowing exactly what we’re dealing with.
Firebox Repair
The firebox is the masonry box where the fire actually burns, and in Martinez’s older homes, it’s frequently the most neglected part of the system. Cracked firebrick, failed mortar joints, and fireboxes that have shifted because the lintel rusted out under marine moisture - all common here. We repair fireboxes with refractory mortar and replace damaged firebrick. If the damage extends into the smoke chamber, we’ll show you on camera before any work is recommended.
BeforeAfterTrusted Brands We Service and Stock in Martinez
We install and service fireplaces, inserts, dampers, and liners from Copperfield, DuraFlex, and HeatShield. The HeatShield liner system is particularly relevant in Martinez’s shared-flue housing, because it lets us isolate a single wood flue within an existing brick stack without tearing out the entire chimney. We keep common replacement parts and damper hardware in our local stock, which means fewer return trips when a repair needs a specific part. That matters when your fireplace is down in December and the wind is howling off the strait.
Common Fireplace Problems We See in Martinez Homes
- Shared-flue cross-contamination in attached housing. In the dense historic blocks off Alhambra Avenue and Escobar Street, multiple fireplaces share one brick chimney stack. When a neighbor’s gas appliance vents into the common flue, their exhaust gets pulled into your wood-burning fireplace. We tested this on a 1920s Craftsman off Alhambra Avenue and found the neighbor’s gas exhaust coming through the wood side of a shared stack. The fix was a HeatShield liner to isolate the wood flue, plus a crown replacement and a wind-directional cap.
- Wind-driven downdrafting from the Carquinez Strait. The Delta breeze is strong enough here to reverse smoke flow in a structurally sound chimney. Wind-directional caps solve most of these cases. We’ve seen it stop a persistent smoke problem in a single visit, on a chimney that had been swept twice by another company with no improvement.
- Sulfur residue from refinery fallout. The Martinez Refining Company on the western edge of town has been part of this area’s air chemistry for decades. Sulfur compounds settle on flue walls, bond with creosote, and eat at terra cotta liners faster than wood smoke alone. If we pull a liner tile that’s yellowed and brittle, that’s not age. That’s chemistry.
- Spalled crowns and rusted dampers from strait moisture. The persistent marine layer off the Carquinez Strait keeps masonry wet. Freeze-thaw cycles in winter produce spalling on exposed brick crowns, and dampers corrode faster than they do inland. If your chimney crown looks like it’s shedding gravel, it is. And it’s letting water into the flue.
Every one of these problems is documented with photos before we recommend a repair. You’ll see the evidence on camera. You decide what gets done and what waits.

FAQs - Fireplace Services in Martinez
The Carquinez Strait channels the Delta breeze through Martinez with enough sustained force to push smoke and carbon monoxide backward into your living space, even when the flue is clean and the damper is open. The most effective fix in almost every case is a wind-directional cap, which rotates with the prevailing wind and blocks sustained pressure from the strait side. We fit these on roughly three out of every four Martinez chimneys we service. Call (980) 580-8641 for a written quote on a cap install.
Yes. Decades of sulfur and hydrocarbon emissions from the Martinez Refining Company have deposited corrosive compounds onto local masonry, and when you burn wood, those compounds bond with the creosote into a chemically aggressive glaze. It’s harder to remove, and it accelerates the deterioration of terra cotta flue liners. That’s why we document liner condition with camera footage on every visit, not just what we can see from the top.
A shared brick stack with multiple flues is supposed to have each flue isolated, but in 80-to-120-year-old construction, the internal separation is often compromised. When a neighbor vents a gas appliance into the common stack, their exhaust can cross into your flue and emerge from your fireplace. The definitive fix is to install a continuous liner - we use HeatShield or DuraFlex - that isolates your wood flue from the shared stack entirely. It’s a one-day installation in most cases, and it permanently separates the two systems. Call (980) 580-8641 for a camera inspection to confirm what’s happening in your stack.
Every year, even if you burn infrequently. The marine layer off the Carquinez Strait keeps masonry damp, which means freeze-thaw spalling, rusted dampers, and crown deterioration happen on a different timeline here than they do in Concord or Walnut Creek. Annual camera inspection catches these things while they’re cheap to fix. Most Martinez homeowners who skip three years end up with a $1,500 crown job or a $3,500 liner replacement that could have been deferred with a $200 maintenance visit.
Older Martinez homes have throat dampers made of cast iron or mild steel, and the persistent moisture off the strait keeps them damp for weeks at a time after a winter rain. They rust, warp, and seize. If you’re fighting the damper lever every time you build a fire, the fix is usually a top-sealing damper mounted at the flue top, which also helps block wind-driven downdrafts. It’s one of the most common repairs we do in Martinez. Call (980) 580-8641 for a written quote.
