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 Chimney Cap & Crown Across Millbrae
Chimney cap and crown work in Millbrae is driven by one thing most other Peninsula cities don’t deal with as hard: persistent coastal fog. A new stainless cap typically costs $245-$540 installed in Millbrae, crown repair runs $180-$420, and full crown rebuilding starts around $650 and goes up from there based on flue count and access. The fog matters because it corrodes metal components faster than heat does. If you’re seeing rust streaks on your chimney, a cap that’s pulling away, or water stains on the ceiling near the fireplace, call (980) 580-8641 and we’ll give you a written price before anything starts.
Why Emberly Chimney Cleaners Is Millbrae’s Preferred Chimney Cap & Crown Company
Millbrae homeowners don’t ask us to trust us. They ask what we found. That’s how we’ve always worked: camera down the flue, photos in hand, and a written scope with a written price delivered before any work begins. Corrine Halstead leads our crews under the Haven Standard, which means Clause 4 applies on every Millbrae visit: a documented photo record from before, during, and after. You’ll see the corroded cap fasteners, the spalled crown mortar, the damper plate that’s rusted shut. Then you’ll see exactly what we did about it.
Our response time to Millbrae runs fast because scheduling is coordinated from the San Francisco Bay Area office and crews serve Millbrae locally. The hillside streets above El Camino Real, the flat ranch tracts near Taylor Middle School, the bungalows along Millbrae Avenue: we know where the fog sits longest and where the 1960s brick chimneys are starting to show their age. Background-checked, uniformed technicians arrive with a named tech assigned, and you get a text when they’re on the way. Every visit includes a camera-scan inspection documented with photos, not a flashlight look.
Our Chimney Cap & Crown Services in Millbrae
Cap Installation
A new cap on a Millbrae chimney has to do more than shed rain. It has to stand up to chloride-laden fog, bird pressure from idle flues, and draft requirements that keep the fireplace usable when Spare the Air allows it. We install stainless steel caps from Gelco and Olympia Chimney, sized to your flue and meshed to keep nesting birds out while still letting the chimney breathe. Installation runs $245-$540 for standard single-flue work, with written pricing before we start.
Cap Replacement
If your cap is galvanized and it’s been on the chimney more than five or six years in Millbrae, it’s already failing faster than the same cap would fail in San Mateo or Redwood City. We see chloride pitting and rust-through on galvanized caps constantly here. Replacement involves pulling the old cap, inspecting the flue crown beneath it, and installing a stainless cap built for marine air. Expect $295-$580 depending on flue size, multi-flue configuration, and whether the mounting hardware also needs replacement.
Crown Repair
The crown is the concrete or mortar slab that caps the chimney chase itself, and in Millbrae crowns take a beating. Fog condensation pools into porous mortar, then the temperature swings between damp nights and dry days cause spalling, where the mortar surface flakes off in chunks. We grind out spalled material, repoint, and coat. Crown repair in Millbrae runs $180-$420 for typical repairs before coating; a full crown rebuild starts around $650. The right repair keeps water out of the flue and the smoke chamber.
Crown Coating
Crown coating is the single most useful preventive step for a Millbrae chimney that sits dormant through months of Spare the Air restrictions. A properly applied crown coating seals the porous surface, so fog condensation beads and runs off instead of soaking in. We use Gelco crown coating after grinding out spalled mortar. Coating alone runs $150-$325 for standard single-flue crowns in Millbrae. It extends the life of the crown and prevents the slow water intrusion that rots the flue liner from the top down.

BeforeAfterTrusted Brands We Service in Millbrae
We stock and install components from Gelco, Olympia Chimney, and Famco for Millbrae jobs. These aren’t generic parts. They’re specified for coastal exposure, where stainless matters and galvanized doesn’t hold up. Keeping these brands in local supply means we can typically get cap and crown work scheduled and finished without the week-plus wait that comes with special-ordering off-market hardware. If your existing cap or crown was installed under another brand and it’s failing, we’ll tell you plainly whether it’s worth repairing or whether replacement makes more financial sense.
Common Chimney Cap & Crown Problems We See in Millbrae Homes
- Rusted cap fasteners and galvanic corrosion on flashing. Marine air in Millbrae attacks the metal joints where the cap mounts and where flashing meets the chimney chase. Galvanized fasteners corrode within five to seven years, opening gaps that let fog-driven moisture run down the exterior and soak into the brick.
- Spalled and cracked crown mortar. Fog condensation pools on porous crowns, and the damp-dry cycle causes surface mortar to flake off. Once the crown surface is compromised, water reaches the flue liner and the smoke chamber. In homes on the western hillside slopes above El Camino Real, the taller chimneys and greater wind exposure make this worse.
- Rusted-shut damper plates in barely used fireplaces. We regularly replace dampers in Millbrae homes where the owner says the fireplace was “barely ever used.” The fog-laden air condensing in an idle flue corrodes the metal damper faster than occasional fires would. A corroded damper plate often signals that the cap above has also failed.
- Bird and rodent entry through missing or damaged caps. Idle flues attract nesting birds, especially starlings and sparrows. A cap with torn or missing mesh lets them in, and the nesting material in the flue creates a draft blockage and a fire hazard. Custom caps with tight, correctly sized mesh solve this without restricting draft.
Pricing for Chimney Cap & Crown in Millbrae, CA
A typical cap installation in Millbrae runs $245-$540 for a standard stainless single-flue cap with mounting hardware. Crown coating adds $150-$325 if the crown is in decent shape and only needs sealing. Full crown repair, including grinding out spalled mortar and repointing before coating, lands between $180 and $420 for most Millbrae homes. A complete crown rebuild on a large or multi-flue chimney starts at $650 and can reach $900 or more on hillside chimneys with steep access. What moves the number: flue count, roof pitch, whether the chase needs masonry repair, and whether the existing cap is a custom size that has to be matched. You’ll always get a written price before work starts, and a written warranty when it’s done.

FAQs - Chimney Cap & Crown in Millbrae
Every year, and the reason is the fog, not the fires. In Millbrae’s marine air, cap fasteners and crown mortar degrade on a five-to-seven-year cycle, and a chimney that sits cold for months between Spare the Air restrictions accumulates condensation damage that an annual visual and camera inspection will catch before the liner is involved. If you haven’t had your cap and crown checked in the last 12 months, call (980) 580-8641 and we’ll put it on the schedule with a written price before we start.
Because marine fog doesn’t care whether you burn wood. Moisture condenses inside an idle flue and corrodes metal dampers, cap fasteners, and liner components faster than occasional use would. The chimney that sits unused for months under Spare the Air restrictions is exactly the one we find with a rusted-shut damper and a failed crown. A working cap and sealed crown keep the moisture out, full stop.
Stainless survives Millbrae. Galvanized doesn’t. Near SFO the fog carries chlorides from the marine layer, and galvanized caps develop pitting and rust-through within five to seven years. Stainless caps from Gelco or Olympia Chimney cost more up front, $245-$540 installed, but they last roughly twice as long in this air. We won’t install galvanized on a Millbrae chimney if you ask us for a recommendation.
Yes. Millbrae’s post-war ranch and bungalow homes often have distinctive brick chimneys, and a custom cap can be fabricated to match the chase dimensions and the visual profile of the original cap. We measure the chase, specify the mesh and material, and install a cap that fits the masonry without looking like a generic add-on. Custom cap work in Millbrae starts around $400 and goes up with size and finish.
Yes, and it’s the most cost-effective preventive step you can take for a Millbrae chimney. Crown coating seals the porous mortar surface so fog condensation can’t soak in and start spalling. For $150-$325 on a typical single-flue crown, you get a sealed surface that won’t absorb moisture during the months the fireplace sits idle. Call (980) 580-8641 for a written quote and a camera inspection, and we’ll show you the current crown condition before any coating is applied.
Know What You’re Paying For in Millbrae
On a hillside street above El Camino Real, we replaced a corroded galvanized cap on a 1960s brick chimney where the damper plate had rusted shut from fog condensation. Our tech installed a DuraFlex stainless steel cap and applied Gelco crown coating after grinding out spalled mortar from the original crown. That job is typical for Millbrae: the cap failed first, the crown was next, and the damper had been corroding quietly for years. What you get from Emberly Chimney Cleaners is a written price, a photo record, and a warranty. No guesses.
