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.

Why Emberly Chimney Cleaners Oakland Is Redwood City’s Preferred Chimney Repair Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a significant share of our repair work comes from Redwood City homeowners who bought mid-century homes and discovered hidden damage the seller’s disclosure never mentioned. Our crews know the local pattern: post-1989 Loma Prieta exterior repairs that look solid from the street but conceal cracked clay flue liners inside. Redwood City customers find us through three-star reviews as often as five-star ones because we show them the camera footage before quoting a dime.
Calls are answered by a live person 24 hours a day, 7 days a week. We assign a named technician, send a text when they’re en route, and deliver a written scope, written price, and written warranty before anyone touches your chimney. That’s Haven Standard Clause 1: Have it in writing. Corrine Halstead built this practice into the company from day one.
Our Chimney Repair Services in Redwood City
Mortar Repointing
Repointing in Redwood City runs $1,200-$2,800 for a typical ranch chimney, with costs climbing when we find earthquake-era patching that hid deeper structural issues. The 60-80 year old brick in Friendly Acres and Stambaugh Hurst was laid with lime mortar that turns to powder faster than modern Portland cement, and Bay Area winter rain accelerates the decay even in Redwood City’s relatively dry microclimate. We grind out failed joints to proper depth, match the original mortar composition, and document the before-and-after under Haven Standard Clause 4. No repointing is quoted without camera evidence of the underlying brick condition.
Spalling Brick Repair
Spalling brick repair in Redwood City typically costs $800-$2,400 depending on how many courses need replacement and whether the damage traces to a cracked crown or failed flashing. Redwood City’s overnight fog and winter rains drive moisture into idle chimneys for months; when that moisture freezes in the brick faces, the surface pops off in flakes. We see this most on south- and west-facing chimneys in the older tracts near Woodside Road, where afternoon sun heats the brick and evening fog cools it fast. We source replacement brick through our Haven buying network to match color and texture, then seal with a vapor-permeable treatment that doesn’t trap moisture inside.
Chimney Waterproofing
Waterproofing a Redwood City chimney costs $450-$950 including crown sealing, vapor-permeable masonry treatment, and flashing inspection. Homeowners here assume the “Climate Best” slogan means their chimney weathers gently, but the reality is more complex: months of disuse let moisture accumulate, then winter rains find every crack. We apply treatments that breathe so trapped moisture escapes, and we never recommend waterproofing without first scoping the flue for liner damage that water may have already caused. Materials come from Copperfield and Famco, procured through Haven’s network.
Flashing Repair
Flashing repair in Redwood City runs $350-$850 for standard chimney-to-roof junctions, higher when we find corroded step flashing on low-slope mid-century roofs. The ranch homes off Middlefield Road and near Redwood Shores often have original galvanized flashing that’s rusted through after 60+ years. We replace with copper or stainless step and counterflashing, sealed with high-temperature silicone, and photograph the completed work for your record.
Chimney Rebuilding
Partial or full chimney rebuilding in Redwood City ranges from $3,500-$12,000, with most projects landing in the $4,500-$7,500 range for above-the-roof reconstruction on a standard ranch home. We rebuild only what’s necessary. If the lower courses are sound and the damage is concentrated at the crown and upper flue, we’ll tell you. Every rebuild includes a new flue liner specification, documented with camera footage of the existing liner condition, and we use DuraFlex stainless liners where the original clay tile is compromised.

Common Chimney Repair Problems We See in Redwood City Homes
- Post-Loma Prieta exterior repairs hiding cracked flue liners. The 1989 earthquake damaged thousands of Redwood City chimneys. Many got repointed and braced on the outside while the clay flue tiles inside stayed cracked. The damage is invisible until scoped, and it’s the single most common surprise we find in Friendly Acres and Stambaugh Hurst.
- Idle, damp flues producing heavy creosote on rare use. Redwood City’s sunny microclimate means fireplaces sit cold and damp for 10-11 months, then generate thick second- and third-degree creosote glaze when finally lit. The flue never dries out properly, and the first fire of winter often reveals a blockage or odor problem.
- Efflorescence and spalling from winter moisture cycles. White chalky deposits on brick signal water moving through the masonry, dissolving salts, and depositing them on the surface. Left alone, the freeze-thaw cycle pops the brick face. We see this advancing fastest on chimneys with cracked crowns or failed flashing near Woodside Road.
- Bird nesting and debris in unused flues. Chimneys that sit idle all summer become prime nesting territory. A single nest can block the flue partially or completely, and the debris combines with creosote to create a serious hazard. Our camera inspection finds this before you light the first fire.

FAQs - Chimney Repair in Redwood City
Most post-Loma Prieta repairs addressed exterior masonry and structural bracing only, leaving the interior clay flue liner untouched. In Friendly Acres we scoped a 1954 ranch whose chimney had clearly been braced and repointed after Loma Prieta - new mortar on the outside, original clay tile liner untouched inside. The camera showed a cracked tile with a second-degree creosote glaze above the smoke chamber, and the appliance venting into that stack had been pushing moisture into the break for years. We documented both on the homeowner’s screen, relined with DuraFlex, and replaced the chimney crown that was shedding water onto the spalling brick. If your chimney was “repaired” in 1989-1990, the exterior work may be sound while the liner is compromised. Only a camera inspection reveals which is which. Call (628) 300-1701 to schedule.
Yes, and Redwood City’s climate makes the case stronger, not weaker. The extreme infrequency of use creates a specific failure pattern: cold, damp flues that generate thick creosote on the rare occasions they’re lit, combined with years of bird nesting and moisture intrusion that go unnoticed because the fireplace “seems fine” all summer. NFPA 211 recommends annual inspection regardless of use frequency, and Redwood City’s idle-flue pattern is exactly why. We include the camera scan and photo record on every visit. Call (628) 300-1701 to book.
Redwood City chimneys accumulate second-degree creosote glaze rather than the fluffy first-degree type seen in colder climates with frequent use. The flue stays cold and damp for months, so when it’s finally lit, the smoke condenses into a hard, shiny layer that sticks to tile and stainless steel alike. Third-degree glazed creosote, which we find in roughly one in five Redwood City inspections, is a concentrated fuel source and the leading cause of chimney fires. Standard brushing won’t remove it; mechanical removal or chemical treatment is required. We document the creosote class on camera and explain what removal method applies before quoting. Call (628) 300-1701 for an inspection.
We don’t recommend relining without camera evidence you can see for yourself, and we deliver that evidence with a written price before any work is proposed. Haven Standard Clause 4 requires a documented photo record on every job, and Clause 1 requires a written price before work starts. If the liner is sound, we’ll say so and show you. If it’s cracked, offset, or glazed with creosote that can’t be safely removed, we’ll show you that too. Our Free Second Opinion policy means you can take our written findings and camera footage to any competitor for comparison. No hidden recommendations, no pressure. Call (628) 300-1701 if you want a second set of eyes on another company’s quote.
The white chalky deposit is efflorescence, and the crumbling is spalling - both caused by moisture moving through the brick. In Stambaugh Hurst’s mid-century ranch homes, the original chimney crowns have cracked after 60-80 years of thermal cycling, and Bay Area winter rain plus overnight fog drives water into the masonry. Redwood City’s mild reputation tricks homeowners into thinking weathering isn’t happening, but the damp winters are real. The crown needs replacement or resurfacing, the brick needs evaluation for structural soundness, and the flue needs scoping for water damage. We document all three with camera footage and deliver a written repair scope. Call (628) 300-1701 for a free estimate.
