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.

AfterTrusted Fireplace Services for San Mateo Homeowners
Fireplace Services - San Mateo typically range from $180 for a gas fireplace tune-up to $2,800 for a full firebox rebuild, with most repairs completed in a single visit. At Level Two Chimney San Mateo, we’ve inspected and serviced more than 38,000 fireplaces and chimneys since 2009, and every job starts with a written price before any work begins. Call (650) 600-3117 to speak with a live person - we answer calls 24 hours a day, seven days a week.
San Mateo’s mild, marine-influenced climate creates a specific problem for fireplace owners: moisture from Pacific fog and winter rains seeps into masonry and gas valve assemblies during long off-seasons, then accelerates corrosion and spalling once fall burning starts. In neighborhoods like Baywood-Aragon and Hillsdale, we regularly find firebox deterioration that went unnoticed because the fireplace “looked fine” from the living room. Our NFPA 211 Level 2 inspection catches what a visual check cannot - a camera down the flue, documented photo record, and written findings you can review before deciding on any repair.

What Our Fireplace Services Service Includes
Gas Fireplace Service
Gas fireplace service covers burner cleaning, pilot and thermopile testing, gas pressure verification, and venting inspection to confirm safe exhaust flow. You need it when the pilot won’t stay lit, the flame pattern looks uneven, or you smell any gas odor near the unit. At Level Two Chimney San Mateo, we use a digital manometer to check inlet and manifold pressure against manufacturer specs, then provide the readings and a written scope before touching a valve - Haven Standard Clause 1 requires it.
Wood Burning Fireplace
Wood burning fireplace service includes firebox inspection, damper function check, smoke chamber evaluation, and creosote assessment to determine sweep needs. You need it before your first fall fire, after any chimney fire event, or if you notice smoke backup into the room. In San Mateo’s older homes near Downtown and Shoreview, we often find degraded mortar joints and Class III glazed creosote - the hard, tar-like deposit that resists standard brushing and requires rotary removal.
Fireplace Insert
Fireplace insert service addresses the specific venting connection between the insert and existing chimney liner, plus combustion air supply and gasket integrity. You need it when the insert smokes, the blower runs loud, or the liner connection has shifted from thermal expansion cycles. We remove the insert to inspect the direct-connect collar and liner top, document any gaps with photos, and quote reconnection or liner extension work in writing - no surprises after we’re in your home.
Damper Repair
Damper repair restores the metal plate that seals your fireplace from outside air when not in use and opens fully for proper draft during operation. You need it when the damper won’t open or close completely, makes grinding noises, or leaks cold air year-round. In San Mateo homes built between 1950 and 1980, we frequently find throat dampers rusted through from decades of salt-laden fog intrusion; we quote top-sealing damper replacement when repair isn’t economical.
Firebox Repair
Firebox repair addresses cracked or missing refractory panels, deteriorated mortar joints, and heat-damaged brick that compromises the fire-containing structure. You need it when you see cracks wider than 1/16 inch, chunks of firebrick missing, or mortar falling into the hearth. We use HeatShield refractory restoration systems for panel resurfacing when appropriate, or source matching firebrick through our Haven buying network for rebuilds that restore structural integrity.
Fireplace Conversion
Fireplace conversion changes your existing wood-burning fireplace to gas, or upgrades an older gas system to modern direct-vent or vent-free operation. You need it when wood burning is restricted by local ordinance, you want thermostat-controlled heat, or the existing wood system is too deteriorated for safe use. We handle gas line coordination, burner selection from approved manufacturers, and permit-compliant installation - with a written price covering the full scope, not a low opening bid that balloons.
Brands We Service for Fireplace Services
We’ve serviced and repaired hundreds of HeatShield refractory systems in San Mateo County, from minor panel resurfacing to full smoke chamber parging. The ceramic coating requires specific surface prep and cure-time protocols; our technicians are trained to HeatShield’s application standards and stock the bonding agent and casting mix for same-visit completion when conditions allow.
We also maintain strong parts access through DuraFlex for flexible liner connections on fireplace insert installations, and source Famco termination caps and draft regulators for gas fireplace venting corrections. Whether your unit is HeatShield, DuraFlex, Famco, or any other make - Majestic, Heatilator, Napoleon, Regency, or a brand that’s been out of production for decades - we can diagnose it, source parts through our network, and fix it with a written warranty.

- Persistent gas odor or sulfur smell near the fireplace. Even a faint rotten-egg odor indicates a gas leak or incomplete combustion that can produce carbon monoxide. We treat these calls as priority response and perform electronic leak detection, pressure testing, and venting verification before declaring the system safe.
- Smoke entering the room during operation. Backdrafting means the chimney isn’t pulling exhaust properly - from damper malfunction, blocked flue, negative pressure from modern HVAC systems, or house-tightening renovations. In San Mateo’s compact lots, neighboring structures can also create wind-related downdraft that requires a specific cap solution.
- Cracked or spalling firebrick with visible gaps. Heat escapes through cracks into surrounding framing, creating pyrolysis risk over time. We document crack patterns with camera photos and measure clearances to combustibles as part of every firebox evaluation.
- Pilot light that won’t stay lit or flames that burn blue then yellow. Yellow tipping indicates incomplete combustion and elevated carbon monoxide production. Our gas service includes thermopile millivolt testing, thermocouple replacement, and burner orifice inspection to restore proper flame chemistry.
- White efflorescence or rust stains on exterior masonry. These are moisture intrusion signatures that accelerate liner deterioration and can freeze-thaw crack the crown. In San Mateo’s wet winters, we see this progression regularly in homes without proper chimney cap protection.

Several factors push prices higher or lower in this market. San Mateo’s hillside homes in Sugarloaf and western hills often require additional roof safety equipment for chimney-top work. Homes built 2015-2025 may have factory-built fireplaces with specific OEM parts that cost more than generic alternatives but maintain warranty coverage. The biggest cost control is getting a written estimate with scope before work starts - the practice that defines our company - so you can compare apples-to-apples with any competitor’s quote. We also offer a Free Second Opinion on any written estimate you bring us.
Every estimate we provide is free and carries no obligation. What we quote is what you pay - no trip charges added after arrival, no “while we’re here” upsells. The price includes the camera inspection, photo documentation, and our 365-Day Done Right Promise.
