Why Hearthstone Chimney Co. of San Francisco Is Redwood City’s Preferred Chimney Repair Company
We’ve worked on chimneys in Redwood City since 1984, back when the downtown was still mostly hardware stores and the Fox Theatre was showing double features. Our technicians know the local housing stock: the 94061, 94062, and 94063 ZIP codes hold a dense mix of Craftsman cottages, postwar bungalows, and mid-century ranch homes, many with original brick chimneys that have never been professionally inspected. Warren Eckhart, our owner, still reviews photos from every Level-2 camera inspection we perform in Redwood City - documented like an engineer, explained like a craftsman.
Our customers in Redwood City return because we show them what we found. Photos they can see. A plain-English verdict. No jargon, no scare tactics. The 90-Day Done Right Promise backs every repair in writing: if it’s not right, we come back. No paperwork, no arguing.

Our Chimney Repair Services in Redwood City
Mortar Repointing
Redwood City’s older neighborhoods, especially around Farm Hill Boulevard and the 94062 hillside, see mortar joints crumble faster than flatter parts of the Peninsula. Rain gets in, freezes rarely but enough, and the lime mortar used in 1950s construction turns to sand. We grind out failed joints to proper depth and repoint with HeatShield refractory mortar, matched to the original joint profile. A typical repointing job on a Redwood City chimney runs $850-$1,400.
Spalling Brick Repair
Spalling - bricks flaking and crumbling from freeze-thaw cycling and moisture intrusion - is common in Redwood City’s 94061 and 94063 ZIP codes where chimneys lack proper crowns or caps. We remove damaged brick, install matching reclaimed or new brick where appropriate, and treat the underlying cause. In the North Fair Oaks corridor, we often find spalling caused by decades of unlined flue use: creosote-saturated brick holds moisture and deteriorates from within. Spalling repair in Redwood City typically costs $1,200-$2,200.
Chimney Waterproofing
Redwood City sits in a protected thermal pocket - warmer and sunnier than San Francisco - but that sunshine masks the real enemy: marine moisture from the Bay, especially in fog-penetrable areas near Edgewood Road and the 94062 ridgeline. We apply professional-grade breathable sealers that let vapor escape while blocking liquid water. Waterproofing a standard Redwood City chimney runs $450-$750 and prevents the spalling and mortar failure that lead to rebuilds.
Flashing Repair
The intersection where your chimney meets the roof is the most leak-prone point on any house. In Redwood City’s older stock, original flashing was often step-flashing only, without counterflashing or proper seal. We fabricate and install copper or galvanized flashing with proper reglets and sealant, integrated with your roofing. Flashing repair in Redwood City typically runs $350-$650 for standard pitches; steep or slate roofs run higher.
Chimney Rebuilding
Some Redwood City chimneys are past repointing. In the 94063 ZIP code, we’ve torn down and rebuilt chimneys where unlined flues, spalling brick, and failed mortar combined to make the structure unsafe. We rebuild with proper liners, solid crowns, and correct clearances to combustibles. A partial rebuild runs $2,200-$3,800; full rebuilds from the roofline up range $4,500-$7,500 in the Redwood City market.
Tuckpointing
For decorative brickwork and historic chimneys in Redwood City’s older neighborhoods, tuckpointing restores the fine-line aesthetic of original construction while sealing the structural joint behind it. It’s specialized work that demands matching mortar color and joint style. We price tuckpointing by the linear foot after inspection.

Trusted Brands We Service in Redwood City
We don’t use builder-grade substitutes. Our Redwood City repairs specify professional-grade materials from Olympia Chimney, Famco, and DuraFlex - brands that hold up to the Peninsula’s marine air and thermal cycling. We stock common liners, caps, and flashing components locally, so most Redwood City customers don’t wait for special orders. When we recently relined that 1952 chimney in North Fair Oaks, the DuraFlex stainless steel liner was on the truck the same morning. Done right, and we stand behind it.
Common Chimney Repair Problems We See in Redwood City Homes
- Unlined masonry flues in 1940s-1960s homes. In North Fair Oaks (94063), many postwar chimneys were built without terra-cotta flue liners. Creosote soaks directly into the brick, creating a hidden fire hazard virtually absent in newer Peninsula cities like Foster City or San Carlos. Full relining is the only safe remedy.
- Foundation micro-settling in Emerald Hills. Homes on sloped lots in the 94062 ZIP code experience seismic movement and minor foundation shifts that crack firebox mortar and offset flue tiles. Gas or smoke can leak into living spaces through these gaps. We inspect for tile offset and mortar separation with our camera system.
- Uncapped flues after gas-insert conversions. Bay Area Air Quality Management District Spare the Air burn bans pushed many Redwood City homeowners to convert wood fireplaces to gas inserts. Too often the flue was left uncapped and uninspected. Moisture and pests enter, deteriorating masonry from within while the homeowner sees nothing wrong.
- Failed chimney crowns and deteriorated caps. Original concrete crowns crack, steel caps rust through, and water enters the chimney structure. In Redwood City’s sun-exposed hillsides, thermal expansion accelerates the damage. We install Gelco and Copperfield caps with proper drip edges and crown wash.

FAQs - Chimney Repair in Redwood City
No. Many 1950s Redwood City homes, particularly in the North Fair Oaks corridor (94063), were built with unlined masonry flues as a cost-saving measure common in California’s postwar construction boom. Our Level-2 camera inspections reveal this condition regularly. If your home dates to this era and has never been inspected, call (855) 408-5567 - estimates are free, and unlined flues require relining for safe use.
Sloped lots in Emerald Hills (94062) experience foundation micro-settling and seismic movement that cracks firebox mortar and offsets flue tiles. Flatland homes don’t see this stress pattern. We inspect Emerald Hills chimneys with particular attention to tile alignment and mortar integrity at the firebox-throat junction. If you live on a hillside lot, annual inspection is prudent - call (855) 408-5567 to schedule.
Yes, and possibly more urgently than before. Many Redwood City conversions left the original flue uncapped and uninspected after Spare the Air restrictions pushed homeowners to gas. Moisture enters, pests nest, and the masonry deteriorates unseen while the gas insert functions normally. We inspect converted flues for cap installation, liner condition, and proper venting. Call (855) 408-5567 for a post-conversion inspection - estimates are free.
Repointing suffices when mortar joints are eroded but bricks remain sound and the chimney structure is plumb. Rebuilding becomes necessary when bricks are spalling, courses are shifting, or the chimney leans. We document this distinction with photos from our Level-2 inspection and give you a plain-English verdict. Most Redwood City chimneys in the 94061 and 94062 ZIP codes need repointing; unlined 94063 chimneys often need more extensive work. Call (855) 408-5567 - we’ll show you exactly what you have.
Unlined masonry flues allow creosote to penetrate the brick itself, rather than depositing on a smooth terra-cotta surface that can be swept clean. Once saturated, the brick acts like a wick - a hot fire can ignite creosote within the masonry, causing a structure fire that starts inside the chimney wall. This risk is essentially absent in lined flues. We recently repaired a 1952 brick chimney in the North Fair Oaks corridor (Veterans Boulevard area) where decades of unlined use had saturated the brick with creosote. Our crew installed a DuraFlex stainless steel liner and repointed the firebox with HeatShield mortar - the only way to bring a legacy, unlined flue up to current safety standards. If your North Fair Oaks home has never been inspected, call (855) 408-5567.
