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 Fireplace Services Across San Mateo
Fireplace service in San Mateo runs $149 to $450 for most cleanings and inspections, with damper repairs starting around $185 and firebox repairs typically landing between $400 and $1,200 depending on what the camera reveals. We schedule San Mateo appointments within a few days, and every visit includes a documented photo record before we recommend anything. If you own one of the 1940s-to-1970s homes in Baywood, Beresford, or east of El Camino Real, your fireplace was likely built with a clay tile flue liner that has now been through 50 to 80 years of Bay Area seismic settling. Call (980) 580-8641 for a written price before any work starts.

Why Emberly Chimney Cleaners Is San Mateo’s Preferred Fireplace Services Company
We built our name on one practice: camera-scan documentation on every chimney we touch. In 2009, we made that the default on every inspection, and it became Clause 4 of the Haven Standard we work under today. That means you see the inside of your flue liner, firebox, and smoke chamber before you spend a dollar on repairs. Our Fireplace Services team has inspected and cleaned more than 38,000 chimneys since then, and every one of those jobs had a written scope, a written price, and a written warranty delivered before the work began. That is not negotiable.
San Mateo customers often tell us the same thing: another company quoted them a new liner after five minutes with a flashlight and no photos. Our answer is always the same. If we cannot show you the crack on camera and give you a written price for the fix, we do not recommend the repair. That discipline matters most in San Mateo specifically, because our clay flue liners and older masonry components take real abuse from salt-laden marine fog and decades of seismic settling near the Crystal Springs corridor. The three-star reviews on our San Mateo jobs usually say the same thing too: thorough, expensive if there is a real problem, and worth it because the evidence was on the screen. Corrine Halstead, who leads our Bay Area operations, insists on this standard on every call we run from Millbrae down to San Carlos.
Our Fireplace Services in San Mateo
Gas Fireplace Service
Gas fireplace service in San Mateo typically runs $175 to $350. Most gas units in Baywood and Beresford homes are 10 to 25 years old, and the salt-laden marine fog east of El Camino Real accelerates corrosion on thermopiles, pilot assemblies, and valves. We clean burners, test gas pressure, check the logs for proper flame pattern, and verify the venting with a camera where accessible. If we find a corroded thermocouple making the unit shut off mid-burn, we show you the part and give you a written price before replacing it.
Wood Burning Fireplace
Wood burning fireplace cleaning and inspection in San Mateo runs $149 to $250 for a standard masonry unit. Here is what most San Mateo homeowners do not realize: your wood fireplace may have sat idle for an entire winter because of BAAQMD Spare the Air alerts, and that is exactly when moisture, raccoons, and rust do their worst work. A visual sweep alone misses all of that. Our Level 2 inspection runs a camera down the flue and through the smoke chamber, documenting what is actually there before anything gets recommended. We also inspect the firebox for spalling brick, which is common in San Mateo because damp Bay air sits inside chimneys between burns and weakens mortar over time.
Fireplace Insert
Fireplace insert installation in San Mateo runs $2,800 to $6,500 depending on the unit and the condition of the existing firebox. This is one of the best upgrades for Bay-side homeowners because a sealed insert solves the two problems this climate creates: marine fog exposure and idle dampness. We source inserts and components through our buying network with DuraFlex and Copperfield, but only quote an install after a camera inspection confirms the firebox and chimney can support one. If the existing firebox has spalling or the flue liner has fractures from seismic activity, that gets addressed in the same written scope, not as a surprise add-on later.
Damper Repair
Damper repair in San Mateo runs $185 to $525 depending on whether we can replace the plate in place or whether corrosion has eaten into the throat assembly. This is the single most common fireplace service call we get in San Mateo between mid-November and late January. Here is the pattern: the first Spare the Air restriction lifts after a long stretch, the homeowner opens the damper to light a fire, and the damper will not move. Salt-laden marine fog has seized the galvanized plate. We replace or refurbish the assembly, lubricate the hinge points, and photograph the repair. Then we confirm the damper actually opens and seals before we leave.
BeforeAfterTrusted Brands We Service in San Mateo
We work on all major brands and fuel types across San Mateo, and we stock common replacement parts locally for faster turnaround. We procure through Famco and Copperfield for dampers and top-sealing products, and DuraFlex for stainless liners when a replacement is actually needed. We do not push specific brands for the sake of margin. We quote the part based on what the camera shows the flue needs, and we write the brand, the model, and the price on the quote before you commit. If you have an old insert you inherited with the house in Beresford or a masonry fireplace off Hillsdale Boulevard that has been dormant for years, we can likely source what it needs without a long wait.
Common Fireplace Problems We See in San Mateo Homes
- Rusted-shut galvanized dampers. Salt-laden marine fog off the Bay corrodes the thin galvanized steel on dampers until the plate binds. If you haven’t opened yours since last spring, do not force it. Forcing a seized damper can break the handle or send rust flakes into the firebox and smoke chamber. Call us and we will inspect it before you lose the first legal burn night.
- Raccoon and bird nests in uncapped flues. When your fireplace sits unused for weeks during Spare the Air season, raccoons move in. They build nests in the smoke chamber and block the draft. Lighting a fire with a raccoon nest in the flue can push smoke into the house and, in the worst case, start a chimney fire. We removed a raccoon nest from a Baywood ranch last November. The damper had seized, the nest was packed in tight, and the clay flue liner showed hairline fractures from decades of seismic settling near Crystal Springs.
- Hairline clay flue liner cracks from seismic activity. The San Andreas Fault runs through the Crystal Springs corridor just west of San Mateo, and decades of minor ground movement have left hairline fractures in countless clay tile liners. These cracks let heat and gases reach the masonry around the flue. A Level 2 camera inspection is the only way to confirm liner integrity before you light the first fire of the season.
- Spalling firebox brick from trapped Bay moisture. Because San Mateo winters stay mild and fires are infrequent, firebox brick stays damp for months. Moisture gets absorbed, then releases slowly, causing the brick face to flake off. It sounds minor. It isn’t. Spalled brick in the firebox can allow heat to transfer to the surrounding framing. We repair fireboxes with proper refractory mortar, not a thin cosmetic patch.

FAQs - Fireplace Services in San Mateo
Yes, and this is the most common mistake we see in San Mateo. A fireplace that sits unused for months in damp Bay air is more likely to have animal nesting, rusted dampers, or moisture-damaged mortar than one that burns regularly. Before you light the first fire after a burn ban ends, schedule a Level 2 camera inspection. We will show you what is inside before you put a match to anything. Call (980) 580-8641 and we will schedule it.
Salt-laden marine fog from the Bay carries corrosive air into your chimney, and galvanized damper plates rust faster in San Mateo than they do in inland cities like San Carlos or Belmont. The fix is usually a replacement plate or a top-sealing damper that closes off the flue from the top of the chimney, where the fog does the most damage. We will show you the corrosion on camera and quote the repair in writing before we start. Call (980) 580-8641 for a free estimate.
Do not light the fire. Raccoons and birds nested in inactive flues during long Spare the Air stretches, and burning with a nest in the smoke chamber can cause a chimney fire or force carbon monoxide into the house. Call us. We remove the animals humanely when possible, inspect the flue with a camera, and repair whatever damage the nest caused. Every visit includes a documented photo record. Call (980) 580-8641 first.
Yes, and it is one of the reasons we run a camera through every flue we inspect. The San Andreas Fault passes through the Crystal Springs corridor just west of San Mateo, and decades of minor seismic settling have left hairline cracks in many clay tile liners. You cannot see these from the firebox. A Level 2 inspection documents whether your liner is intact or whether you need a stainless replacement. If we recommend one, you get the camera images. No exceptions. Call (980) 580-8641 for an inspection.
It means your fireplace might be legally unburnable on many winter nights, which has a side effect we see constantly in San Mateo: chimneys sit idle in damp Bay air for weeks, and the dampness accelerates rust, mortar decay, and animal nesting. The program itself does not damage your fireplace. Inactivity in a marine fog environment does. The answer is not to burn when prohibited. The answer is to have the chimney inspected before the first legal burn so you do not lose that first clean-air night to a seized damper or a raccoon nest. Call (980) 580-8641 and we will get it checked.
