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 Chimney Liner & Rebuild for San Mateo Homeowners
A chimney liner or rebuild in San Mateo typically costs $1,800 for a stainless steel liner installation up to $8,500-$15,000 for a full chimney rebuild, with most liner replacements completed in one to two days. Since 2009, Level Two Chimney San Mateo has completed more than 38,000 chimney inspections and cleanings across the Peninsula, and every liner and rebuild job starts with a camera-scan NFPA 211 Level 2 inspection, a written price before any work begins, and a documented photo record when it’s done. Call (650) 600-3117 for a free estimate - estimates include the camera inspection and written scope at no charge.
San Mateo’s coastal climate brings salt air and seasonal moisture that accelerates liner deterioration in masonry chimneys, particularly in older homes near the Bay in neighborhoods like Baywood-Aragon and Shoreview. We’ve found clay tile liners cracked by thermal shock in homes built during the 1960s and 1970s housing boom, and we’ve documented corrosion in stainless steel liners installed without proper condensation management facing the Pacific breeze. Our technicians are background-checked, uniformed, and assigned by name - you’ll get a text when we’re on the way, and our live phone support runs 24 hours a day, 7 days a week.
What Our Chimney Liner & Rebuild Service Includes
Stainless Steel Liner
A stainless steel liner is a continuous metal flue pipe inserted through the existing chimney structure to contain combustion gases and protect masonry from heat and corrosive byproducts. In San Mateo, we install stainless steel liners when clay tile flues have cracked, shifted, or suffered spalling - surface flaking caused by freeze-thaw cycling and salt air exposure - or when a new high-efficiency appliance requires a correctly sized flue. Our stainless steel liners are sourced through our Haven buying network from DuraFlex and Olympia Chimney, with gauge and alloy selected based on your fuel type and appliance rating, and every installation includes a smoke test, draft reading, and the documented photo record required by Clause 4 of the Haven Standard.
Flexible Liner
A flexible liner is a corrugated stainless steel tube that navigates offsets and bends in chimney structures where a rigid pipe cannot pass, common in San Mateo’s hillside homes in Sugarloaf and Laurelwood with angled or stepped flue paths. We specify flexible liners from DuraFlex when the existing chimney has non-linear construction, when relining must work around structural obstructions, or when a top-down installation minimizes interior disruption. Our crews measure the flue path with a video camera before ordering material - no guesswork on length or diameter - and the written scope specifies alloy grade, insulation wrap if required for zero-clearance, and the warranty term before we start.
Liner Replacement
Liner replacement removes a failed or incompatible existing liner and installs new material matched to your current heating appliance and fuel type. We’ve replaced liners in San Mateo that were incorrectly sized for converted gas inserts, liners damaged by chimney fires in wood-burning systems, and original clay liners degraded by decades of condensation in oil-to-gas conversions in the Parkside and Beresford neighborhoods. Every replacement starts with our NFPA 211 Level 2 inspection to document why the existing liner failed - so the new one doesn’t - and ends with a written warranty and the 365-Day Done Right Promise.
Partial Rebuild
A partial rebuild addresses structural failure limited to the chimney crown, upper courses of brick, or the top few feet of flue liner while preserving sound lower structure. In San Mateo, we see partial rebuild needs after water intrusion through deteriorated crowns - common where Pacific fog drives moisture into hairline cracks that expand with winter temperature swings - or where seismic movement has shifted the top section of older chimneys in the San Mateo Village area. Our partial rebuilds include tear-down to sound masonry, installation of a poured concrete or pre-formed crown with proper overhang and drip edge, and matching brick or stucco finish to existing exterior.
Full Chimney Rebuild
A full chimney rebuild dismantles the existing structure to the roofline or foundation and constructs new masonry, flue system, and exterior finish to current California Building Code and NFPA 211 standards. We perform full rebuilds in San Mateo when structural integrity is compromised by long-term water damage, seismic shifting, or advanced spalling throughout the stack - conditions we’ve documented in pre-1950s homes in Aragon and in chimneys with failed flashing that allowed decades of concealed rot. Every full rebuild includes engineered footing if required, a new stainless steel or properly insulated liner, a cricket on the upslope side for wide chimneys, and the complete photo record archived under Clause 4 of the Haven Standard.
Liner Repair
Liner repair addresses localized damage - small cracks, gaps at joints, or minor corrosion spots - without full replacement, when the liner’s overall condition and remaining wall thickness support restoration. We use HeatShield cerfractory sealant for certain clay tile repairs and localized stainless steel patching where appropriate, but we won’t recommend repair over replacement unless the camera evidence shows the liner can safely perform for its expected service life. In San Mateo, liner repair is sometimes viable in newer installations with isolated mechanical damage or in chimneys with limited use patterns; we’ll show you the footage, explain the numbers, and write the price for both options so you decide.

Brands We Service for Chimney Liner & Rebuild
We source and install materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield through our Haven buying network, with pricing kept honest by volume agreements and direct relationships. We’ve installed hundreds of DuraFlex flexible liners in Peninsula homes with offset flues and angled chimney paths, and we stock common diameters and termination components for same-day starts when the inspection is complete. Our HeatShield applications follow manufacturer specifications for surface prep, thickness, and cure time - we don’t cut corners on a product whose performance depends on installation discipline.
Whether your existing liner is from Famco, Copperfield, or any other manufacturer, we can evaluate its condition, match or upgrade its specification, and document the result. We don’t require you to use our preferred brands - we require that whatever goes in your chimney meets NFPA 211, carries a written warranty, and is installed to a written scope you approve before work starts. That’s Haven Standard Clause 1: have it in writing.

AfterSigns You Need Chimney Liner & Rebuild Right Now
- White staining or efflorescence on exterior brick indicates water moving through the masonry, dissolving salts, and depositing them on the surface. In San Mateo’s fog-driven climate, this often means the liner has cracked or the crown has failed, allowing moisture to saturate the chimney structure and accelerate freeze-thaw damage during winter cold snaps.
- Flakes or pieces of clay tile in the firebox or cleanout mean the flue liner is spalling - shedding material under thermal stress or age deterioration. These pieces obstruct draft, create hotspots in adjacent masonry, and can block the flue entirely; we’ve documented chimney fires in San Mateo homes where spalling debris ignited accumulated creosote.
- Strong smoke odor when the fireplace is not in use suggests downdraft or negative pressure pulling air down a damaged or improperly sized flue, often combined with liner gaps that allow smoke smell to permeate living spaces. This is common in tightly sealed modern homes in the Bay Meadows and Hillsdale areas where HVAC systems compete with chimney draft.
- Rust stains on the chimney face or metal components signal persistent water intrusion, typically through a failed crown, deteriorated flashing, or liner breach that’s allowing combustion condensation to contact steel components. Salt air from the Bay accelerates this corrosion in San Mateo compared to inland climates.
- Visible cracks in the chimney crown or missing mortar joints create entry points for water that will destroy the chimney from the top down. A cracked crown in October becomes saturated masonry by January, and by the following winter you’re looking at partial or full rebuild rather than crown repair - we’ve traced the progression in dozens of San Mateo inspections.
Our Chimney Liner & Rebuild Process - Step by Step
- 1
NFPA 211 Level 2 Inspection with Camera Scan - We lower a high-resolution video camera the full length of your flue to document liner condition, joint alignment, creosote classification, and any obstructions or structural anomalies. In San Mateo, we specifically look for salt-air corrosion patterns, seismic displacement at offsets, and condensation damage from high-efficiency appliances vented into oversized flues. You receive the footage and a written condition report before any work is discussed.
- 2
Written Scope, Written Price, Written Warranty - Based on the inspection findings, we prepare a single-document proposal with exactly what we’ll do, what materials we’ll use, what it costs, and what warranty applies. Haven Standard Clause 1 requires this in writing before work starts - no verbal estimates, no “we’ll see when we get into it” pricing. For liner and rebuild work, we also provide a Free Second Opinion on any competitor’s written estimate if you want comparison.
- 3
Scheduled Execution with Named Technician - Once you approve the scope, we book the work with a background-checked, uniformed technician assigned by name. You get a text when they’re en route, and they arrive with the specified materials - no supply-house runs on your clock. For liner installations, we typically schedule one to two days depending on roof access and liner length; full rebuilds are staged with weather contingency.
- 4
Installation with Ongoing Documentation - During the work, we photograph critical stages: liner insertion and connection, insulation wrap placement, crown pour and finish, brick coursing and joint profile. These images become part of your permanent record under Haven Standard Clause 4, available on request for insurance, real estate transaction, or your own reference. We perform smoke tests and draft readings on every liner installation to verify performance before we leave.
- 5
Final Walkthrough and Archived Record - We review the completed work with you, explain what was done and what maintenance schedule applies, and deliver your final documentation packet: photos, readings, written warranty, and our 365-Day Done Right Promise. If anything isn’t right, we make it right - no argument, no delay. The record stays in our archive, and you can call (650) 600-3117 any time for clarification or follow-up.
How Much Does Chimney Liner & Rebuild Cost in San Mateo?
A typical stainless steel liner installation in San Mateo runs $1,800-$3,400 for a straightforward single-flue replacement with standard roof access and no structural modifications. Flexible liner installations in offset chimneys range $2,200-$4,100 depending on length, diameter, and whether insulation wrap is required for zero-clearance compliance. Partial rebuilds - crown replacement, upper course rebuild, and new cap - generally fall between $3,500 and $6,500. Full chimney rebuilds in San Mateo start around $8,500 and can reach $15,000 or more for multi-flue structures with complex scaffolding, historic matching requirements, or engineered footing work.
| Service | Typical Range in San Mateo | What Drives the Price |
|---|---|---|
| Stainless steel liner (rigid) | $1,800 - $3,400 | Flue diameter, height, roof access, appliance connection type |
| Flexible liner | $2,200 - $4,100 | Length, offsets, insulation requirement, termination style |
| Liner replacement (tear-out and install) | $2,800 - $5,200 | Existing liner material, disposal, structural repairs needed |
| Partial rebuild (crown to top courses) | $3,500 - $6,500 | Height of rebuild, brick matching, crown type, flashing integration |
| Full chimney rebuild | $8,500 - $15,000+ | Flue count, height, footing condition, scaffolding, finish match |
| Liner repair (HeatShield or patch) | $800 - $2,400 | Extent of damage, access, whether full replacement is more economical |
What affects your specific price: flue height and diameter (taller chimneys in hillside neighborhoods like Sugarloaf require more material and longer rigging), roof pitch and access (steep roofs or limited setback add scaffolding cost), existing liner material and condition (concrete or heavily corroded steel takes longer to remove), and whether the installation requires NFPA 211-compliant insulation or special termination for your appliance type. We don’t estimate by phone - we inspect, we camera-scan, we write the price. That’s the only way to avoid the low-ball opener that balloons once the crew arrives.
How to avoid overpaying: get the inspection and written scope from any provider, then bring us the written estimate for a Free Second Opinion. We regularly find that competitor quotes omit necessary components - proper insulation, code-compliant termination, or crown repair - or specify undersized liners that will fail prematurely. Our written price includes everything required for a compliant, warranted installation; nothing is added after the fact.
What’s included in our free estimate: the NFPA 211 Level 2 camera inspection, the written condition report, the scope proposal with material specifications, and the price. No charge, no obligation. Call (650) 600-3117 to schedule.
