Why Ashby Chimney San Jose Is Union City’s Preferred Chimney Inspection Company
We’ve inspected hundreds of Union City chimneys since 2002, and the pattern here is consistent: older tract homes with original masonry flues, moisture working its way through crowns and caps, and homeowners who never got a straight answer from the last guy who showed up. That last part is what keeps us busy. Union City homeowners call us after a no-show, after a quote that doubled at the door, after a repair that cracked again in six weeks. They want a company that writes the price down before work starts and puts the guarantee in writing when the job’s done. That’s how we’ve always worked.
Every inspection gets a written price before we step on the roof. Every repair gets a written guarantee. If a repair fails inside the guarantee period, we come back free. That’s the 365-Day Done Right Promise, and it applies to every job we do in Union City. Background-checked technicians in uniform, live phone answers around the clock, and no voicemail roulette. You know who’s showing up and what it costs before the ladder comes off the truck.

Chimney Flue Inspection in Union City
Chimney Flue Inspection in Union City is the part of the job that finds what you can’t see from the hearth: cracked clay tile liners, creosote glazing, and gaps where heat and carbon monoxide escape into the chimney chase. In older Union City homes, especially along the Mission Boulevard corridor, clay tile liners crack from decades of seismic settling on the Hayward Fault. A flue inspection with a camera is the only way to see that damage before it becomes a chimney fire or a carbon monoxide leak. Most flue inspections here run $199 to $449 depending on whether we’re running a camera through a single flue or a multi-flue chase.
Camera Inspection for Clay Tile Liners
The older Decoto and Alvarado homes often have original clay tile liners that haven’t been inspected once since the house was built. A camera scan shows every crack, joint offset, and spalled tile face, and you watch the footage with us on the spot. If the liner is compromised, we show you the video before we ever quote a repair.
Flue Inspection Before Home Sale
Real estate transactions in Union City usually require a Level 2 camera inspection, especially for homes built before 1980. Realtors and home inspectors call us for this because the report includes timestamped photos and a written summary they can hand to the buyer. If you’re selling, don’t wait until escrow to find out your flue liner is shot. Get the inspection done before the buyer’s inspector flags it.
Chimney Fire in Union City
Chimney Fire in Union City is the emergency every older tract home risks when creosote builds up in an unlined or damaged flue. The marine layer pushes moisture into chimneys here, and wet creosote burns hotter and sticks harder than the dry powder you’d find in an inland climate. Most chimney fires we respond to in Union City started in flues that hadn’t been inspected in five to ten years. A Level 1 inspection after any chimney fire runs $250 to $450, and a Level 2 camera inspection after a structural fire runs $400 to $700 because we’re documenting every inch of the flue for insurance.
Signs a Chimney Fire Already Happened
Look for puffy or honeycombed creosote, warped metal caps, cracked flue tiles, or discolored masonry on the exterior. If you hear a loud rumble like a freight train from the chimney and see flames shooting from the top, call 911 first. Then call us once the fire is out. We’ll document the damage and tell you what’s safe to repair versus what needs replaced.
Prevention Starts With Inspection
We recommend an annual Level 1 inspection for anyone burning wood in Union City, even if it’s only a few fires a year. The salt air here corrodes caps and flashing faster than inland homes, and moisture-damaged liners fail sooner. Catching a cracked tile or corroded cap early costs a few hundred dollars. Waiting until the fire happens costs thousands.
Trusted Brands We Service in Union City
We repair and replace components from HeatShield, Gelco, and Olympia Chimney, which matters because the materials we use are built for coastal conditions. HeatShield’s resurfacing system works well in Union City where relining is often the most economical fix for cracked clay tile liners. We keep common parts stocked for fast turnaround on Union City jobs, so we’re not waiting a week on a flue tile or cap while your fireplace sits unusable. When we quote a repair, we tell you the brand and show you the part before it goes in.
Common Chimney Inspection Problems We See in Union City Homes
- Cracked clay tile liners from Hayward Fault settling. Decades of seismic movement along the fault crack the rigid clay tiles in older chimneys, letting heat and gases escape. Camera inspection is the only way to see the damage, and HeatShield resurfacing often saves a liner without a full rebuild.
- Corroded galvanized caps and flashing from salt air. The marine layer accelerates rust on galvanized components, usually within 5 to 7 years. We replace them with stainless steel, which holds up to the coastal exposure far longer.
- Efflorescence and spalling on exterior masonry. Moisture from the marine layer wicks through the brick and leaves white mineral deposits, then the brick face pops off in freeze-thaw cycles. This is structural decay, not a cosmetic issue, and it gets worse every year it’s ignored.
- First-degree creosote from occasional burning. Homeowners who burn a few fires a year still get creosote buildup, especially with wet wood or a restricted draft. Annual inspection catches it before it becomes a tar glaze that’s far harder to remove.

FAQs About Chimney Inspection in Union City
Once a year, even with light use. The salt air and marine-layer moisture in Union City corrode caps and flashing year-round, whether you burn or not. An annual Level 1 inspection catches rusted components and early creosote before they become expensive problems. Call (669) 266-5073 to schedule yours before burning season.
Stainless steel, full stop. Galvanized caps fail within 5 to 7 years in the salt air that drifts over Union City from the Bay. Stainless holds up for decades and costs only marginally more up front. We stock stainless caps and can install one the same day as your inspection.
The Hayward Fault runs along this side of the Bay, and decades of minor seismic settling crack rigid clay tile liners. Homes in Decoto built in the 1950s and 60s are especially prone because the liners are original and the mortar has degraded. A camera inspection shows the exact extent, and HeatShield resurfacing often fixes it without a full rebuild. Call (669) 266-5073 and we’ll show you the footage ourselves.
A Level 1 inspection covers the accessible portions of the flue and fireplace, runs $189 to $349, and is the right choice for an annual check when nothing has changed. A Level 2 inspection adds a full camera scan of the flue interior, runs $299 to $599, and is required for real estate transactions or after a chimney fire or seismic event. We’ll tell you which one you need and why, with the price in writing before we start.
Yes. The marine layer carries salt and moisture that accelerate mortar decay, especially on crowns and flashing, and you’ll see white efflorescence streaking down the brick as the first sign. Left alone, the crown cracks and lets water into the chimney structure. We repair crowns with a waterproof sealant, and the work carries the same written guarantee as everything else we do. Call (669) 266-5073 for a quote.
What Union City Homeowners Should Ask Before Any Inspection
Here’s the street-level guide we promised. Before any company inspects your Union City chimney, ask three questions. First, will the price be written down before the technician arrives? Second, will there be photos or video of every finding, or just a verbal summary? Third, does the repair quote carry a written guarantee, and for how long? On a 1960s tract home in Decoto, our tech found a corroded galvanized chimney cap and spalling brick on the crown, with efflorescence streaking the exterior masonry from decades of marine-layer moisture. We replaced the cap with a stainless steel unit, repaired the crown with a waterproof sealant, and noted first-degree creosote in the flue, catching it before it became a tar glaze. That’s the kind of detail you should expect in a report. If a company can’t answer those three questions, call someone who can. Call (669) 266-5073 and ask for Nathan Corliss. He’ll give you straight answers before we ever book the appointment.
