Fast, Reliable Chimney Inspection Across Sunnyvale
Chimney inspection in Sunnyvale typically costs between $189 and $489 for a standard Level 1 or Level 2 inspection, and most appointments are completed within 90 minutes. If you own a 1950s or 60s ranch home off El Camino Real, Mathilda Avenue, or near the Sunnyvale Community Center, that fireplace has likely never had its flue liner examined. A Sunnyvale Chimney Sweep from Ashby Chimney San Jose serves local homeowners with inspections that show you exactly what’s inside your chimney, on camera, before you light a fire. Call us at (669) 266-5073 to schedule.
Why Ashby Chimney San Jose Is Sunnyvale’s Preferred Chimney Inspection Company
Sunnyvale has more original post-war masonry fireplaces per block than almost any city in Santa Clara County. Those chimneys are 55 to 70 years old now. Nathan Corliss and our technicians understand what that means, because we see it every week: cracked clay flue tiles from seismic settling, crowns with spalling along the back edge, and missing rain caps on homes that haven’t been inspected since they were built. We don’t come to Sunnyvale to upsell you. We come to show you the actual condition of your flue, with a camera, and give you a written price for only what it actually needs.
Our team answers the phone live, 24 hours a day. You call, a person picks up. You’ll get a written price before any work starts, and every inspection includes a written report with photos. No surprises at the door. Sunnyvale customers keep calling us back because the number we quote is the number on the invoice.
Our Chimney Inspection team is background-checked and uniformed, so you know exactly who’s walking in. And we back every repair with the Kingswell Guarantee: if a covered repair fails during the guarantee period, we return and fix it at no charge. That’s the 365-Day Done Right Promise in writing.
Styles & brands we work with
Chimney Inspection Services in Sunnyvale
Chimney Inspection Services in Sunnyvale cover three levels defined by the National Fire Protection Association: Level 1 for chimneys in continued use with no changes, Level 2 when the property is being sold or after an event like an earthquake, and Level 3 when hidden damage is suspected and access is required. Most Sunnyvale homeowners booking a first inspection on a 1960s ranch need a Level 2, because the home has changed hands or the chimney hasn’t been examined in decades. A Level 1 inspection in Sunnyvale runs $189 to $249. A Level 2 camera inspection runs $319 to $489 depending on flue height and access.
Real Estate Inspection Support
If you’re buying or selling a home in Sunnyvale, a Level 2 inspection with video documentation is the standard. We provide a written report the buyer and seller can both understand, with clear photographs. We’ve inspected homes near Raynor Park, Cherry Chase, and De Anza Boulevard where the seller had no idea the original clay liner was cracked until our camera showed it.
What a Sunnyvale Inspection Includes
Every inspection covers the firebox, damper, smoke chamber, flue liner, crown, and exterior masonry. We check for creosote loading, water intrusion, and structural shifting. You get a written summary before we leave, not a call back next week.

Chimney Flue Inspection in Sunnyvale
Chimney Flue Inspection in Sunnyvale focuses on the liner, the clay or steel tube that vents combustion gases out of your home. In this city, where most flues are original single clay tiles installed between 1950 and 1970, a flue inspection is often where we find hairline cracks from decades of minor earthquake movement. Those cracks matter, because they let heat, sparks, and carbon monoxide reach the surrounding masonry and framing.
Camera Inspection
We run a video scan the full length of your flue so you can see every crack, offset, and glaze deposit. You watch the screen with us. Nothing is hidden. In Sunnyvale, a camera flue inspection is $319 to $489 as part of a Level 2, and it’s the only way to accurately document seismic stress cracks in clay liners.
Flue Condition Reports
After the scan, we give you a written report with still images and a plain-English explanation of what we saw. If your flue is fine, we say so and put it in writing. If it needs a HeatShield liner repair or a new stainless liner, we quote it separately, with the Kingswell Guarantee covering the repair.
Trusted Brands We Service in Sunnyvale
When a Sunnyvale chimney needs repair after an inspection, we don’t improvise with whatever’s in the van. We use materials from HeatShield for cast-in-place liner repairs, Olympia Chimney for caps and dampers, and Gelco for specialty chase covers and stainless components. These are recognized chimney-trade manufacturers, and we stock common Sunnyvale sizes so the repair doesn’t stall while parts ship. If you’ve had a liner crack in a 1960s flue, HeatShield is the repair we quote most often, because it restores the full length of the original clay without tearing out masonry.
Common Chimney Inspection Problems We See in Sunnyvale Homes
- Cracked clay flue tiles from seismic settling: Sunnyvale sits a few miles from the San Andreas and Calaveras faults. Minor movement over six decades leaves hairline cracks that are invisible without a Level 2 camera scan, and those cracks can let carbon monoxide into the home.
- Spalled crowns without rain caps: Many original Sunnyvale chimneys were built with no cap. Rain settles on the crown, slowly eroding the mortar, and water travels into the smoke chamber. By the time you see a water-stained ceiling, the crown has been failing for years.
- Third-degree creosote glaze: Fireplaces used for ambiance rather than consistent heat can develop a hard, shiny creosote glaze that a standard brush cleaning cannot remove. It’s a fire hazard, and it requires chemical treatment or mechanical removal we identify during inspection.
- Unlined or under-lined flues in older tracts: Some post-war Sunnyvale chimneys were built with a single clay tile and never upgraded. That’s legal to maintain, but it means the margin for error is zero. We document what’s there and tell you plainly whether it’s safe to burn.

FAQs About Chimney Inspection in Sunnyvale
Every year, no exceptions. A 60-year-old masonry chimney in a seismically active area can develop a cracked flue tile or shifted crown in a single season. Annual inspection catches it before it becomes a fire or carbon monoxide problem.
Cracked clay flue tiles from decades of minor seismic settling. These cracks are invisible without a video scan, and they can let combustion gases leak into the wall cavity. A HeatShield liner repair is the standard fix we quote when we find one. Call (669) 266-5073 to schedule your inspection.
If you’ve used the fireplace within the past year and nothing has changed, a Level 1 at $189 to $249 may be adequate. But if the home changed hands, if the chimney hasn’t been examined in years, or if you felt any noticeable shaking from a recent earthquake, a Level 2 is the responsible choice. We’ll tell you which level you actually need, not which one makes us more money.
Yes. A missing rain cap means water has been entering the flue directly, and that is often how crown spalling and efflorescence start. We’ll document the water entry in your written report and quote a proper Olympia Chimney cap in the same visit. The cap itself is one of the cheapest repairs we do in Sunnyvale.
First-degree creosote is a fine, brushable powder. Third-degree is a hard, glazed deposit that resembles tar and can ignite at much lower temperatures. Many Sunnyvale fireplaces are used lightly but consistently, which can produce exactly the conditions for glaze. If we find third-degree creosote during inspection, the fireplace is not safe to burn until it’s been removed. Call (669) 266-5073 and we’ll walk you through it.
What We Actually See Inside a 1950s-60s Sunnyvale Chimney
Because Sunnyvale sits just a few miles from the San Andreas and Calaveras faults, minor seismic settling means unlined or single-flue-tile masonry chimneys in 1950s-60s ranch homes are often hiding cracked flue liners or shifted crowns that only a Level 2 inspection with a video scan reveals. That’s not a theory. Our crew drove out to a ranch house off El Camino Real near the Sunnyvale Community Center, where the homeowner had just bought the place and wanted the original 1959 fireplace checked before first use. We found a single clay flue tile with a hairline crack from decades of seismic settling, a crown with spalling along the back edge, and no rain cap, so water had been seeping into the smoke chamber, leaving efflorescence on the firebox wall. We documented it with a Level 2 camera scan, quoted a HeatShield liner repair and a new custom crown, and left the owner with a clear report before they ever lit a match. That’s what a Sunnyvale inspection actually looks like.
