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.

Sunnyvale’s ranch-style housing stock presents a specific cap and crown problem: original 1960s chimneys in neighborhoods like Birdland were often finished with a sloped mortar wash instead of a proper concrete crown, and decades of Bay Area winter rain have cracked that thin layer, letting water erode mortar joints and spall brick faces that you’ll never see from the ground. That’s why our Chimney Cap & Crown work and liner evaluations are the two most common jobs we dispatch in Sunnyvale - the damage is hidden, cumulative, and only visible once the camera goes down the flue.
Why Sunnyvale Homes Are Different
Sunnyvale’s built environment was shaped by Lockheed and early semiconductor growth, and the housing stock reflects it: tens of thousands of single-story California ranch homes built between 1950 and 1975, most with original brick masonry fireplaces and clay-tile flue liners that have never been upgraded. Frequent real estate turnover driven by the tech economy means new buyers - often relocating engineers unfamiliar with older California construction - inherit chimneys with completely unknown service histories.
The climate compounds the neglect. Overnight lows rarely dip below the low 40s °F, so fireplaces burn for ambiance, not heat, sometimes only 3-8 times per winter. This low-and-slow pattern leaves acidic creosote condensation in flues that never fully warm, while long idle seasons between uses create prime nesting conditions for starlings and raccoons entering through uncapped or deteriorated crowns. In the Lakewood area and Birdland, we’ve pulled nests from chimneys that hadn’t been inspected since the original owner moved out in 1987.
Our Main Sunnyvale Services
These are the three services Sunnyvale homeowners book most often; each has its own dedicated Sunnyvale page with deeper detail.
Chimney Cleaning & Sweep in Sunnyvale
Our Chimney Cleaning & Sweep in Sunnyvale starts with a full NFPA 211 Level 2 inspection - camera down the flue, photo record, written condition report - because in 50-70 year old chimneys, the creosote you can’t see is usually worse than what you can. We remove Class I through III deposits, check for obstructions from wildlife, and document liner integrity before certifying the system safe to use.
Chimney Repair in Sunnyvale
Our Chimney Repair in Sunnyvale addresses spalling brick, eroded mortar joints, and water damage that originated with failed crowns or missing caps. Most repairs we quote in Sunnyvale trace back to that original mortar-wash crown detail; we rebuild with proper concrete crowns, stainless steel caps, and flashings sourced through our Haven buying network.
Fireplace Services in Sunnyvale
Our Fireplace Services in Sunnyvale cover gas conversion, insert installation, damper repair, and smoke chamber parging for homeowners who want to keep the original fireplace functional but safe. Many Sunnyvale owners are surprised to learn their damper has corroded shut or their smoke chamber has never been parged - both standard findings on our camera inspections.

AfterChimney Cap & Crown in Sunnyvale
Chimney cap and crown work is our most frequent dispatch in Sunnyvale because the original construction was inadequate and the consequences are now urgent. In Birdland and Lakewood, 1960s chimneys were topped with a sloped mortar wash - not a poured concrete crown with proper overhang and drip edge - and that thin layer has cracked, admitting rain that spalls brick and erodes mortar joints from the top down. The damage is invisible from street level and only revealed when our camera inspection documents flaking liner tiles, stained smoke chamber walls, or rusted damper frames. Our Chimney Cap & Crown service replaces these failed assemblies with proper concrete crowns, stainless steel or copper caps, and integrated spark arrestors.
Crown Repair
Signs you need it
Cracks or missing chunks in the concrete crown top, water stains on the firebox walls, or spalled brick faces on the chimney exterior above the roofline.
What it costs in Sunnyvale
Crown repair in Sunnyvale typically ranges from $450 to $1,200 depending on whether we’re sealing hairline cracks or pouring a new crown with proper reinforcement and overhang.
How we do it
We grind out damaged material, form and pour a new concrete crown with minimum 2-inch overhang and drip edge, then seal it with a breathable waterproofing agent before installing the cap.
Cap Replacement
Signs you need it
Rust holes in a galvanized cap, a cap blown off in wind, or animal nesting debris visible in the firebox indicating no cap or a failed screen.
What it costs in Sunnyvale
Cap replacement in Sunnyvale runs $280 to $650 for standard stainless steel single-flue models, with multi-flue or custom copper caps priced higher.
How we do it
We measure the flue tile or crown footprint, fabricate or source a properly sized cap with integrated mesh screen, and secure it with masonry anchors or a skirt that sheds water past the crown edge.
What Chimney Cap & Crown Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Crown repair (seal minor cracks) | $450-$650 |
| Crown replacement (pour new) | $850-$1,200 |
| Stainless steel cap (single flue) | $280-$450 |
| Stainless steel cap (multi-flue) | $480-$650 |
| Crown coating (preventive) | $350-$550 |
Can a cracked crown wait until next year?
Usually not in Sunnyvale - our wet winters seep through cracks, freeze-thaw cycles expand them, and by spring you’re looking at liner damage or interior water stains that cost far more than crown repair. Call (650) 229-6358 for a camera inspection and written quote.
Will a new cap stop all water intrusion?
A cap stops rain entering the flue directly, but without a sound crown with proper overhang, water still runs down the chimney exterior and enters through porous brick or failed flashing - we assess both before quoting.
Chimney Liner & Rebuild in Sunnyvale
Chimney liner work in Sunnyvale is driven by age, not abuse: original clay flue tiles in 1950s-1970s ranch homes have endured decades of thermal cycling, earthquake micro-movements, and acidic creosote condensation from low-temperature burns, and they crack or spall without warning. Because these chimneys were built before modern venting requirements, many lack liners entirely or have deteriorated tiles that no longer contain combustion gases. Our Chimney Liner & Rebuild service installs stainless steel or flexible liners rated for all fuel types, with full camera documentation of the before condition.
Stainless Steel Liner
Signs you need it
Visible cracks or missing pieces in clay flue tiles on camera inspection, smoke odors in upstairs rooms, or a home inspector flagging the chimney as unlined in a sale transaction.
What it costs in Sunnyvale
Stainless steel liner installation in Sunnyvale ranges from $2,800 to $4,500 for a standard masonry fireplace, including demolition of damaged tile, insulation wrap, and top plate.
How we do it
We remove damaged clay tiles with specialized breakers, measure the flue precisely, drop a 316Ti stainless steel liner with corrugated flex sections as needed, insulate with ceramic blanket, and seal with a top plate and proper termination.
Partial Rebuild
Signs you need it
Significant spalling or missing brick above the roofline, a chimney lean visible from the yard, or mortar joints eroded to finger-width gaps that compromise structural stability.
What it costs in Sunnyvale
Partial rebuild in Sunnyvale typically runs $3,500 to $6,500 depending on height, scaffolding needs, and whether the crown and cap also require replacement.
How we do it
We dismantle to sound masonry, salvage reusable brick where possible, rebuild with matched materials and proper bonding, install a new concrete crown, and cap before documenting with photos.
What Chimney Liner & Rebuild Costs in Sunnyvale
| Item | Typical range in Sunnyvale |
|---|---|
| Stainless steel liner (standard fireplace) | $2,800-$4,500 |
| Flexible liner (with offsets) | $3,200-$5,000 |
| Liner replacement (remove old, install new) | $3,500-$5,500 |
| Partial rebuild (above roofline) | $3,500-$6,500 |
| Full chimney rebuild | $8,500-$15,000 |
Does every old chimney need a new liner?
Not necessarily - we camera-inspect first, and if clay tiles are intact with no gaps or spalling, we document that and recommend continued maintenance. Only damaged or missing liners require replacement, and we show you the camera evidence before quoting.
How long does a stainless steel liner last?
A properly installed 316Ti stainless liner carries a lifetime warranty and typically outlasts the homeowner; we back our installation with the 365-Day Done Right Promise and a written warranty under Haven Standard Clause 1.

We stock caps, liners, and repair materials from Gelco, Olympia Chimney, and Famco through our Haven buying network, with most standard sizes available for next-day installation. Custom copper or specialty caps typically arrive within 3-5 business days. See our brands for the full lineup.
