Chimney Repair in Fontana — You See the Footage Before You Get a Price

Trusted Chimney Repair for Fontana Homeowners

Fontana homes work hard through hot summers and the occasional cold, windy night when you actually light a fire. When a chimney stops drafting properly or water starts staining the ceiling near the flue, the problem is rarely the firebox alone. It’s usually the cap, crown, flashing, or liner. That’s where we come in. Ashwood Chimney Sweep has repaired chimneys across Fontana, Rialto, Bloomington, and the surrounding Inland Empire communities for years, and we handle everything from cracked crowns to full liner replacements using professional-trade materials only. One call to (833) 805-3229 gets an honest assessment and a repair that’s done right, not patched.

Chimney Cap Installation

Chimney cap installation is the single most effective way to keep water, birds, and debris out of a flue that doesn’t already have one. A properly fitted cap sits on top of the flue tile or crown and keeps rain from running down the inside of your chimney, which is a leading cause of liner damage in Fontana homes. We install stainless steel and copper caps from Olympia Chimney and Copperfield, the same manufacturers specified on commercial buildings and high-end custom homes. Installation typically runs $180 to $340 depending on flue size and whether the crown needs prep work first.

Why We Use Trade-Grade Caps

Big-box caps are thin, short-lived, and often don’t fit correctly. We stock caps from Olympia Chimney and Copperfield because they’re built for decades of sun exposure, rain, and the occasional Fontana dust storm. The material difference is obvious when you hold them side by side.

A Cap Pays for Itself

Water is the most expensive problem a chimney can have. A $250 cap prevents thousands in masonry and liner damage down the road. If your flue is uncapped or has a rusted-out Home Depot special on it, fix it before the next rainy season.

Chimney Cap Replacement

Chimney cap replacement is needed when an existing cap has rusted through, blown off in high winds, or simply no longer fits after crown or flue work. Fontana gets strong Santa Ana winds each fall, and we regularly see caps that have shifted or detached entirely. We remove the old unit, inspect the flue and crown underneath, and install a correctly sized replacement from Copperfield or Olympia Chimney. Most replacements run $190 to $400, depending on flue dimensions and whether the old cap was secured properly or just caulked in place.

When Replacement Beats Repair

If the mesh is intact but the top is warped, a cap can sometimes be salvaged. But once the base flange rots or the screening tears, replacement is the only honest fix. We’ll show you the old cap and explain exactly why it failed before quoting the new one.

Custom Sizing for Odd Flues

Older Fontana homes often have non-standard flue openings. We measure on-site and order the correct cap rather than forcing a universal fit. A loose cap rattles all winter and invites animals inside.

Chimney Liner Installation

Chimney liner installation involves replacing or adding the inner lining of your flue, the surface that contains smoke, heat, and combustion byproducts. Fired clay tile liners crack over decades of use, and Fontana’s temperature swings don’t do old masonry any favors. When a liner has gaps or cracks, the chimney is no longer safe for fires. We install DuraFlex flexible stainless steel liner systems, which are certified for wood-burning, gas, and oil applications. A full liner installation typically runs $2,500 to $4,800 depending on chimney height, flue diameter, and accessibility, and we stock the components to get it done without waiting on a distributor.

DuraFlex: What We Use and Why

DuraFlex is a professional-grade liner system unavailable at retail outlets. We’re stocked and certified to install it, which means your liner comes from a manufacturer that supplies chimney contractors, not weekend DIYers. The material is 316L stainless steel, built to handle high heat and corrosive flue gases.

When HeatShield Makes More Sense

Not every damaged liner needs full replacement. If your clay tile liner has minor cracks or spalling but is structurally intact, we can restore it with HeatShield, a specialist-grade product we apply directly to the flue walls. This costs significantly less than a full liner and can extend the life of your chimney by years.

Chimney Flashing Repair

Chimney flashing repair addresses the metal transition where the chimney meets your roof, the most common source of chimney-related roof leaks in Fontana. Flashing fails when the metal corrodes, caulk dries out, or roofers install it incorrectly in the first place. We remove the old flashing, prep the masonry, and install new step and counter flashing that’s properly interwoven with your shingles. Repairs typically run $450 to $900, while full flashing replacement on a larger chimney can reach $1,200.

Why Caulk Isn’t the Fix

We see chimneys every season where someone ran a bead of caulk along the flashing line. It fails quickly because chimneys expand and contract with heat. Proper flashing is metal, not sealant, and needs to be cut into the mortar joints to work correctly.

Water Goes Where It’s Invited

If you’re painting over a water spot on your ceiling near the chimney, the leak has been there a while. By the time flashing repair becomes visible inside the house, drier areas around your firebox have usually been exposed to moisture too. We fix the flashing and inspect what the water may have touched on its way down.

Chimney Crown Repair

Chimney crown repair fixes the concrete or mortar slab on top of your chimney, the first line of defense against water. Crowns crack for a lot of reasons: sloppy original mixing, no expansion joint, or decades of freeze-thaw cycles that stress the material. Once water gets into the crown, it seeps into brick and causes spalling and leaks. We rebuild or reseal crowns with a proper bond break and overhang so water sheds away from the chimney. Crown repair typically runs $350 to $800, depending on the size of the crown and the extent of the damage.

What a Good Crown Looks Like

A correct crown overhangs the brick by at least two inches and slopes away from the flue. A flat crown or one without a drip edge is a leak waiting to happen. We see dozens of Fontana chimneys with this problem every year.

Sealant as a Short-Term Fix

A flexible crown sealant, applied correctly, can buy a few extra years if the crown hasn’t structurally failed. But if the slab is cracked through or the mortar under it is washing away, the crown needs a full rebuild, not a coating.

Chimney Repair Companies

Chimney repair companies in Fontana fall into a few groups: sweep-only outfits that will document problems but can’t fix them, masonry contractors who understand brick but not flue dynamics, and full-service operations like Ashwood Chimney Sweep that handle the entire system. If you’ve gotten a red-flag inspection report and been told to call someone else, that’s the difference. We assess, quote, and complete the repair under one roof, and we’re the company other local inspectors refer people to.

What to Ask Before Hiring

Ask whether the company handles liners directly or subcontracts. Ask what brand of liner they install. Ask if they can show you the damage with a camera. If the answer to any of these is vague, get a second opinion. We show you photos of every problem before we quote a fix.

One Crew, One Standard

When the inspector and the repair tech are different people from different companies, details get lost. Ashwood handles the whole flue, not just the easy parts, and the same person who diagnoses the issue does the repair. That’s how you avoid paying for a problem that never gets solved.

Chimney Masonry Repair

Chimney masonry repair covers the brick, mortar, stone, and structural elements of the chimney itself, the parts that hold everything together. Fontana’s heat, wind, and occasional rain wear down mortar joints over time, and spalling brick, where the face of the brick pops off, is common on older homes in the city. We repoint deteriorating mortar, replace damaged bricks, and rebuild sections of chimney that have shifted or cracked. Masonry repair costs range from $500 for small repointing jobs to $3,000 or more for significant rebuilds of the chimney’s upper section.

Repointing vs. Rebuilding

Repointing means cutting out bad mortar joints and replacing them with fresh mortar matched to your existing color and strength. If bricks themselves are failing or the stack is leaning, you need partial rebuilding. We’ll tell you straight which one your chimney needs and why.

The Mortar Match Matters

Too many masons use modern Portland cement mixes on older chimneys, which traps moisture and causes bricks to fail faster. For homes built before the 1960s, we use softer lime-based mortar that allows the wall to breathe. It’s a detail most Fontana chimney companies skip.

Brands We Service

We repair and service chimneys across Fontana built by every major manufacturer. Whether you have a wood-burning fireplace from Majestic or Superior, a gas insert from Heatilator or Heat & Glo, or an older masonry fireplace that predates today’s popular brands, we can diagnose and fix the problem. Our repair materials come from Famco and Copperfield, professional chimney supply houses that require contractor credentials to buy from.

We install DuraFlex liners and stock caps from Olympia Chimney. We also work with Gelco for select masonry repair products. If you have a Heatilator, Heat & Glo, Majestic, Superior, Vermont Castings, or any other make, call us at (833) 805-3229 to schedule an inspection and get an honest recommendation.

Signs You Need a Pro Right Now

• Water stains on the ceiling near your chimney. This means water is getting past the flashing, crown, or cap and traveling down through your home. The longer it runs, the more wood and drywall get damaged. It won’t dry out on its own.
• Crumbling brick or mortar on the chimney exterior. If you see pieces of brick or mortar on your roof, in the gutters, or at the base of the chimney, the structure is actively failing. Spalling brick exposes the inner chimney to more moisture, accelerating the damage.
• A strong smell of smoke in the house after a fire. This often indicates a drafting problem that could be a partial blockage, a failing liner, or an improperly sized cap. Draft issues concentrate carbon monoxide inside the home instead of venting it outside.
• Visible cracks in the flue liner during a flashlight check. Clay tile liners crack from years of expansion and contraction. Once cracked, the liner can no longer safely contain the heat and gases from your fire. This is a safety issue, not cosmetic.
• A rusted or missing chimney cap. An open or rusted-out cap lets rain pour directly down the flue. It also invites birds, squirrels, and other animals to nest inside, creating blockages and odors. Rust means the cap has done its job and needs replacement.

Our Process, Step by Step

When you call Ashwood Chimney Sweep for chimney repair in Fontana, here’s what happens:

1. 1
   We schedule a full inspection. Every repair starts with a camera inspection of the flue. We run a high-resolution camera through the entire length of the chimney so you can see exactly what we see, not just hear about it from a distance.
2. 2
   We show you the evidence. After the inspection, we review the photos with you on-site. You’ll see cracks, gaps, water damage, or animal activity before we talk about any repairs. Nothing gets recommended without proof you can look at yourself.
3. 3
   We quote the work in writing. Every quote is itemized with the specific materials and labor included. We tell you what’s urgent and what can wait. You’ll never get a vague estimate that balloons after we start.
4. 4
   We complete the repair with trade-grade materials. Liner work uses DuraFlex. Caps come from Olympia Chimney or Copperfield. Masonry repair uses mortar matched to your chimney’s age and original composition. No shortcuts, no bargain-bin materials.
5. 5
   We inspect our own work before we leave. We run the camera again after the repair, show you the before and after, and explain what was done. If we also cleaned the chimney, you’ll see a clean flue with no debris remaining.
