Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Bonita, CA
Chimney repair in Bonita usually means dealing with a fireplace that’s been quietly aging since the Reagan administration. Most homes here were built between the 1970s and 1990s, and their masonry chimneys, prefab metal inserts, dampers, and spark screens are now at the age where failures show up. We handle the full range: cracked crowns, rusted-out caps, deteriorating flue liners, and flashing that’s let water into the chase. Acorn Chimney Sweep has served Bonita since 2015, and we carry the repair materials on the truck so we can often fix what we find the same day. Call (844) 510-0293 to talk through what you’re seeing.
Why Bonita Homes Are Different
Bonita sits against open space, and the canyon-edge and hilltop properties carry a fire-severity designation that changes how a chimney should be maintained. The job here isn’t only about creosote removal. It’s about keeping a spark from leaving the flue and landing in dry brush. Homes built into the slope near Bonita Road or along the Sweetwater River corridor deal with wind patterns that push embers sideways during Santa Ana events. A missing spark screen or a cracked spark arrestor on a cap is a single glowing ember away from a problem.
The housing stock shapes the repairs we do most. Ranches and two-story builds from the 1970s through the 1990s are common, many with masonry fireplaces that have never had a liner camera inspection. Prefab metal inserts from that era are another regular find, and on the east side especially, screens and caps are frequently gone. Without them, birds and rodents move in during the long idle stretches between winter fires. The climate is mild and basically frost-free, so creosote builds slowly from short, cool, smoky fires – then sits for months while nests and wind-blown debris pack into the flue. By the time someone calls us, the chimney often has two problems: the one they noticed and the one blocking the flue.
Styles & brands we work with
Our Main Bonita Services
Most Bonita homeowners reach out to us for one of two reasons: a fireplace that needs sweeping and inspection, or a dryer vent that’s gone too long without cleaning. Both are services we handle as core work, not add-ons.
Chimney Sweep in Bonita
A sweep in Bonita means removing creosote and clearing out whatever the Santa Anas blew in or the local wildlife dragged in. We run brushes sized to the flue, inspect the cap and screen, and note anything that’s failing before it becomes a chimney fire or a water leak. If your fireplace has been used sparingly and smells musty, the issue is often nesting debris rather than heavy creosote. Chimney Sweep in Bonita covers what to expect and what a typical local sweep costs.
Dryer Vent Cleaning in Bonita
Dryer vents here are often long runs through walls, under floors, or up through the roof, especially in the two-story builds. Lint accumulates in those runs, restricts airflow, and becomes a fuel source sitting right next to a heat source. We clean the full run from dryer to termination, verify the exterior vent opens properly, and alert you to any section that’s sagging or disconnected. Dryer Vent Cleaning in Bonita has the local specifics and pricing.

Chimney Repair in Bonita
Chimney repair in Bonita is driven by two local realities: homes old enough for original fireplaces to be failing, and a fire-risk environment where damaged caps, missing screens, and cracked liners are not cosmetic issues. The most common calls involve water getting in through a cracked crown or failed flashing, and flue liners that have spalled to the point where they can no longer safely contain the heat and gases. We inspect with a camera, show you the footage, and repair what actually needs it – which is why our Chimney Repair service starts with evidence, not a sales pitch.
Chimney Cap Installation
Signs you need it
You hear birds or rodents in the flue, or you can see daylight where a cap should be sitting.
What it costs in Bonita
Chimney cap installation in Bonita typically runs $225 to $475, depending on flue size and the cap material.
How we do it
We measure the flue, select a properly sized cap with spark-arresting mesh from our stocked Copperfield and Gelco components, secure it with mechanical fasteners, and confirm the mesh spacing meets the standard for your fuel type.
Chimney Cap Replacement
Signs you need it
The old cap is rusted through, the mesh is torn or missing, or the cap has lifted in the wind and no longer sits flush on the flue tile.
What it costs in Bonita
Chimney cap replacement in Bonita generally falls between $250 and $500, including removal of the old unit and disposal.
How we do it
We pop the degraded cap, inspect the flue tile edge for damage, and install a new cap with a proper spark screen sized for the existing flue – not a universal-fit piece that rattles loose in the first Santa Ana.
Chimney Liner Installation
Signs you need it
You see flaky tile pieces in the firebox, the masonry is spalling, or a camera inspection shows gaps between flue tiles that let heat and gas reach the chimney structure.
What it costs in Bonita
Chimney liner installation in Bonita typically runs $2,500 to $5,500, depending on the liner system and the flue’s length and shape.
How we do it
We size the flue, pull a DuraFlex flexible liner system through, connect it to the appliance or fireplace at the bottom, insulate where the code requires it, and terminate with a proper cap and flashing at the top.
Chimney Flashing Repair
Signs you need it
You see water staining on the ceiling near the chimney, damp drywall in the firebox area, or rusted metal where the chimney meets the roofline.
What it costs in Bonita
Chimney flashing repair in Bonita usually lands between $250 and $700, depending on how many sides of the chimney are involved and the roofing material.
How we do it
We remove the old flashing, install new step and counter flashing with proper overlap, seal the joints with a urethane-based sealant that handles movement, and verify the water path runs away from the chimney chase.
Chimney Crown Repair
Signs you need it
You see cracks in the concrete surface at the top of the chimney, pieces of crown missing, or water staining running down the exterior brick or stucco below the crown line.
What it costs in Bonita
Chimney crown repair in Bonita typically costs $250 to $700, depending on crack severity and whether resurfacing or partial rebuild is required.
How we do it
We chip out deteriorated crown material, build a proper overhang with a drip edge where needed, apply a bonded crown coat that sheds water, and re-bed the cap on top.

| Chimney cap replacement | $250 – $500 |

How do I know if my chimney liner is actually bad?
The only honest answer comes from a camera inspection. We push a camera up the flue and show you the footage. If the tiles are cracked, missing, or gap-spaced, that’s a liner problem. If they’re intact and the flue is sound, we’ll tell you that too and leave it alone.
Does a cracked crown really matter if it doesn’t rain much?
Yes, because the damage is slow and cumulative. Water seeps into the crack, sits in the masonry, and the occasional winter rain or marine layer condensation keeps it damp. The crown spalls wider each year, and eventually the flue tile below it starts to fail. Call (844) 510-0293 if you can see cracks from the ground.

Prices in Bonita move upward when we’re working on a steep roof, when a prefab fireplace from the 1970s or 80s has no off-the-shelf cap that fits, or when debris and nesting material have packed the flue and the job takes longer than a standard sweep. What doesn’t surprise you is the final number: we agree on the scope and price before the work starts, and you see the camera footage before anyone recommends a liner or crown repair.

FAQs About Chimney Company in Bonita
Most repair estimates in Bonita happen within a week of your call, and sweeping can often be scheduled within a few days. If you’re seeing water actively leaking into the house or you suspect a flue blockage, tell the dispatcher when you call (844) 510-0293 and we’ll prioritize the visit.
Most chimney sweeping, cap replacement, and liner work does not require a permit from San Diego County. If we’re doing structural masonry work that changes the chimney’s footprint or height, we’ll tell you before we start whether a permit needs to be pulled. HOA rules vary by development, and a cap or chase cover that alters the roofline is generally the item an HOA might want to review.
Yes. That’s one of the reasons we structured the company this way. A Bonita home with a wood-burning fireplace and an electric dryer has two separate venting systems that both need periodic cleaning, and one appointment covers both. Mention it when you book, and we’ll build the time into the schedule.
