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.

AfterChimney Cleaning in Cupertino, CA
A chimney sweep in Cupertino typically costs $189-$289 for a standard NFPA 211 Level 2 inspection and cleaning, with most appointments completed in 60-90 minutes. We include a camera-scan of the flue, a written photo record, and a written price before any work starts on every visit. For Cupertino’s 1960s-1980s ranch homes with original masonry chimneys, the real concern isn’t just creosote-it’s earthquake-era cracks and animal nesting in idle flues that only a camera inspection reveals. Call (669) 291-2770 to book or get a free estimate.
Why Cupertino Homes Are Different
Cupertino’s housing stock is overwhelmingly 1960s-1980s tract and ranch-style construction from Silicon Valley’s suburban expansion, and most original brick or concrete-block chimneys have never been relined. The 1989 Loma Prieta earthquake and ongoing seismic activity along the Hayward and San Andreas faults left hidden damage-stepped diagonal cracks at mortar joints, displaced flue tiles, failed smoke-chamber parging-that looks cosmetic from the roofline but shows up immediately on camera.
The mild climate means only 10-20 nights per year justify a fire. Those low-temperature, damp-weather burns produce thick stage-2 creosote disproportionate to use, and chimneys sit idle 10+ months, inviting Vaux’s swifts, starlings, and raccoons into uncapped flues. In older neighborhoods near Monta Vista, we regularly find original masonry flues retrofitted with gas inserts or aftermarket stainless liners-sometimes unpermitted and incorrectly sized.

AfterChimney Cap & Crown in Cupertino
Most Cupertino chimneys were built without caps or with thin galvanized crowns that have rusted through after 40+ years of mild, wet winters. A proper cap keeps raccoons and starlings out of flues that sit idle most of the year, while a sound crown diverts rain from mortar joints already stressed by seismic settling. Chimney Cap & Crown work is where we prevent the water intrusion and animal damage that turn into $3,000+ rebuilds.
Cap Installation
Signs you need it
You hear scratching in the flue, see debris on the smoke shelf, or find the flue open to the sky from the roof.
What it costs in Cupertino
Standard single-flue stainless cap installation runs $189-$340; multi-flue custom caps for larger Cupertino ranches range $340-$620.
How we do it
We measure the flue tile or liner outside dimension, select a Gelco or Olympia Chimney cap with proper mesh clearance, and secure it with tapcon screws into the crown-not the flue tile-then photograph the install.
Crown Repair
Signs you need it
You see cracks wider than 1/8 inch running across the crown top, or water staining on the ceiling near the chimney breast inside.
What it costs in Cupertino
Crown crack sealing and resurfacing runs $450-$890; full crown pour for spalled or separated crowns ranges $1,200-$2,400.
How we do it
We grind out cracks to solid concrete, apply bonding agent, and trowel a sloped crown with drip edge; for full pours we form and pour 4,000-psi concrete with embedded mesh over a weekend cure.
What Chimney Cap & Crown Costs in Cupertino
| Item | Typical range in Cupertino |
|---|---|
| Single-flue cap installation | $189 - $340 |
| Multi-flue custom cap | $340 - $620 |
| Crown crack repair / coating | $450 - $890 |
| Full crown replacement | $1,200 - $2,400 |
How long does a chimney cap last in Cupertino’s climate?
Quality stainless caps last 15-25 years in Cupertino’s mild, non-freezing climate; galvanized caps typically fail in 5-8 years from winter moisture and summer UV. We install only stainless or copper from Gelco and Olympia Chimney with a written 10-year warranty.
Can a cracked crown wait until next season?
Hairline cracks can be sealed, but cracks that let water reach the brick freeze-thaw cycle will expand; in Cupertino’s wet winters, that means spalling brick and liner damage within 1-2 seasons. We document the crack width and depth on camera so you can see whether it’s a seal or a pour.
Chimney Liner & Rebuild in Cupertino
Cupertino’s original 1960s-1980s masonry chimneys were built with clay flue tiles that crack in seismic events and erode from infrequent, cool burns. When we camera-inspect during cleaning, we regularly find displaced tiles, gaps at mortar joints, and unpermitted gas insert retrofits venting into oversize flues-a carbon monoxide risk that homeowners can’t see from the hearth. Chimney Liner & Rebuild work restores safe venting with documented materials and sizing.
Stainless Steel Liner
Signs you need it
Your clay flue tile is cracked, your gas insert vents into an unlined masonry flue, or your home inspection flagged “recommend liner evaluation.”
What it costs in Cupertino
Flexible stainless liner with insulation and top plate runs $2,800-$4,500 for a typical single-flue Cupertino ranch chimney.
How we do it
We drop a camera first, measure the flue and appliance BTU rating, then install a DuraFlex or Olympia Chimney listed liner with poured insulation around it and a new cap.
Partial Rebuild
Signs you need it
Your chimney leans, shows stepped diagonal cracks at mortar joints, or has spalled brick with exposed inner courses.
What it costs in Cupertino
Tear-down and rebuild from the roofline up typically runs $3,500-$7,500 depending on height and access; full rebuilds from the ground start around $12,000.
How we do it
We scaffold to NFPA standards, dismantle to sound structure, and rebuild with matching brick and a new crown, documenting each course with photos for your record.
What Chimney Liner & Rebuild Costs in Cupertino
| Item | Typical range in Cupertino |
|---|---|
| Flexible stainless liner (installed) | $2,800 - $4,500 |
| Liner replacement (existing chase) | $1,800 - $3,200 |
| Partial rebuild (roofline up) | $3,500 - $7,500 |
| Full chimney rebuild | $12,000 - $18,000+ |
Does every old chimney need a new liner?
No-intact clay flue tiles in good condition meet code for open wood-burning fireplaces. We camera-inspect to verify; if tiles are cracked or a gas appliance has been added, NFPA 211 requires a listed liner sized to the appliance.
How long does a stainless liner last?
Lifetime-rated 316Ti stainless liners typically last 20-30 years with annual inspection; we warranty our DuraFlex and Olympia Chimney installations for 20 years and document the install date in your photo record.
