Fast, Reliable Chimney Sweep Across Covina
A chimney sweep in Covina typically runs $189 – $289 for a standard fireplace with a Level 1 inspection included, and most Covina homes are back to safe burning within a couple hours of our tech arriving. We work throughout 91722, 91723, and 91724, from the mid-century tracts off Citrus Avenue to the hillside pockets above the 210. Walnut Chimney has spent years pulling bird nests, clearing decade-old creosote, and finding cracked clay-tile liners in Covina fireplaces, and the single most important thing we tell homeowners here is this: nobody should recommend a reline until you’ve seen the problem with your own eyes on a camera screen. Call (855) 341-3461 for a free estimate, and we’ll book a sweep that fits your schedule before the first cold snap.

Why Walnut Chimney Is Covina’s Preferred Chimney Sweep Company
Most of Covina’s fireplaces sit in mid-century tract homes that haven’t seen a professional sweep in years, sometimes decades. That’s not a criticism of the homeowners. It’s what happens when a fireplace gets lit five or six times a winter and nobody thinks about it the other eleven months. Russ Dempsey built Walnut Chimney around the idea that a sweep call should end with a homeowner understanding exactly what’s going on inside their flue, not with a vague warning and a quote for thousands of dollars of work they can’t verify. We’re the company Covina homeowners call when they want a straight answer about their chimney.
We run a camera down every flue we sweep, and we show homeowners what we’re seeing. If the clay-tile liner in your 1962 tract home off Barranca is cracked and spalling at the joints, you’ll see it on-screen before anyone talks about HeatShield resurfacing or a DuraFlex liner. That approach has earned us a steady stream of calls from Covina homeowners who got a quote elsewhere and wanted a second set of eyes before spending money.
Our techs know Covina’s housing stock. The 91722 and 91723 tracts were built fast in the 1950s through the 1970s, and the fireplaces in those homes share common failure patterns: rough smoke chambers, sticky dampers, and clay liners that crack after repeated hot-cold cycles. The 91724 hillside homes, built later, lean more toward prefab metal fireboxes with factory flues. Different problems, different fixes, and we bring the right materials for both. Call (855) 341-3461 if you’re in Covina and need a sweep or a straight answer about what’s going on inside your chimney.
Styles & brands we work with





Chimney Services in Covina
Chimney Services in Covina means more than running a brush up and down a flue. It’s a full-system check: firebox, damper, smoke chamber, flue, and cap. A standard sweep and Level 1 inspection in Covina runs $189 – $289, and a Level 2 inspection with video documentation runs $350 – $550, which is the inspection Covina homeowners ask for after a chimney fire, before buying a mid-century home, or when they’ve skipped sweeps for ten years and want to know what they’re actually dealing with.
Sweep With Camera Inspection
Every Covina sweep we do includes a camera run through the flue and a photo report emailed to you afterward. We document what we find: creosote thickness, liner condition, any nests or debris. If something needs repair, you’ll have the images to prove it, not just a tech’s word.

Creosote And Soot Removal
Creosote removal in Covina homes typically runs $150 – $250 as part of a sweep when the buildup is first-degree and brushable. If we find heavy glazed creosote from years of smoldering fires, that’s a separate discussion. We’ll show you the flakes on the camera screen and explain what it takes to get your flue back to safe condition before recommending anything.

Chimney Sweep Certified in Covina
Chimney Sweep Certified work in Covina means the person on your roof knows how to identify a spalling clay-tile liner, a corroded factory flue, and a smoke chamber that’s been dumping smoke back into the living room for years. Our techs trained for this, and Russ Dempsey holds them to a standard that a lot of Covina homeowners tell us they haven’t found elsewhere. Fireplace cleaning runs $150 – $225 in Covina, and a full sweep with Level 1 inspection lands in that $189 – $289 range I mentioned up top.
Level 1 And Level 2 Inspections
A Level 1 inspection in Covina is $189 – $289 when paired with a sweep, and it covers what’s accessible: the firebox, damper, flue, and cap. A Level 2 inspection, $350 – $550, adds video documentation of the flue interior and the exterior structure, including the attic, crawlspace, and roof flashing. We push for Level 2 on older Covina homes when we suspect liner damage or when the chimney hasn’t been used in years.
Annual Sweep Scheduling
The smart move in Covina, especially in 91722 and 91723, is to book your sweep before Thanksgiving. The first cold snap after Thanksgiving triggers calls from homeowners who discover their long-dormant fireplaces are blocked by nests or won’t draw at all. Get on our calendar in October and you’ll avoid the rush.

Trusted Brands We Service in Covina
When a Covina fireplace needs repair beyond a sweep, we don’t just pick one product and hope it fits. We work with tried-and-tested brands like HeatShield for ceramic resurfacing, DuraFlex for flexible liner systems, and Famco for caps and covers. That means your 1960s clay-tile flue gets a fix matched to the actual condition of the tile, not a generic liner crammed into whatever space we find. We keep common parts in our truck for the repair patterns we see most in Covina: cracked caps, corroded dampers, and deteriorated mortar at the flue joints. When we’re on your roof in Covina, we either have what we need or can get it quick. We’re not waiting on a warehouse across the country.

AfterCommon Chimney Sweep Problems We See in Covina Homes
- Bird and squirrel nests in flues on mature lots. The valley oaks and eucalyptus shading Covina’s 1950s and ’60s tracts make chimney caps attractive nesting sites every spring. We routinely pull nests, and sometimes whole desiccated carcasses, out of flues on 91722 homes that haven’t been swept in a decade.
- Cracked and spalled clay-tile liners. Covina’s original clay liners weren’t built for decades of heating-cooling cycles. We find hairline cracks at the joints on fires that still look fine from the firebox, and nobody should be recommending a reline without showing you the camera footage. We show it.
- Stuck dampers on mid-century fireboxes. The damper on a 1960s Covina fireplace often seizes after years of disuse. That’s usually a minor repair job, not a liner replacement. We’ll show you which is which before you spend a dime.
- Soot and debris accumulation on dormant fireplaces. Most Covina chimneys see light, intermittent burning. The real work here is clearing years of soot, first-degree creosote, and nest debris from flues that haven’t been touched since the Clinton administration, clearing the blockages so the first fire of the season actually draws.
Pricing for Chimney Sweep in Covina, CA
In Covina, a standard chimney sweep with a Level 1 inspection runs $189 – $289. Fireplace cleaning alone runs $150 – $225. A Level 2 inspection with full video documentation runs $350 – $550. Creosote removal for first-degree buildup is included in the sweep price; heavy glaze is priced separately after we document exactly what we’re dealing with. What changes the price in Covina is mostly the height and pitch of your roof, how long it’s been since the last sweep, and whether we’re also pulling nests or clearing a blocked cap. Homes off Citrus Avenue and Barranca in 91722 tend to be single-story, which keeps things simpler; some of the hillside 91724 builds have steeper roofs that take more time to access safely. Call (855) 341-3461 and we’ll give you a straight number before we come out, not after.

FAQs About Chimney Sweep in Covina
You should expect a thorough sweep that clears decade-old soot, first-degree creosote, and quite possibly a bird or squirrel nest. A sweep like this in Covina typically runs $189 – $289, and we’ll run a camera down the flue to document the liner condition. If we find cracks or spalling, you’ll see it on-screen before anyone talks about repairs. Call (855) 341-3461 for a quote on your specific home.
Yes, and here’s why: dormant fireplaces in Covina still accumulate soot, creosote, and nest debris, and the liner cracks we see on mid-century clay-tile flues happen even with light use. A Level 1 inspection with your sweep catches blockages before the first cold snap, and a Level 2 at $350 – $550 gives you video proof of your flue condition. The alternative is discovering the problem the first time smoke rolls back into your living room. Call (855) 341-3461 to schedule.
In Covina homes, smoke spillback usually comes down to a blocked flue from nests or debris, a stuck damper, or a rough smoke chamber on a 1950s – 70s firebox. We’ve also seen cracked clay-tile liners collapsing inward and choking the draft. We diagnose it on-site, show you the problem on camera, and either sweep it clean or give you a straight answer on what’s needed. Call (855) 341-3461 and we’ll come take a look.
Most Covina chimneys carry first-degree, brushable creosote: flaky, sooty, and dry. That’s the result of light, intermittent burning on long-dormant fireplaces. You don’t see the heavy glaze deposits common in mountain towns where fires burn all day and night. But any creosote, even first-degree, is combustible, and we clear it every sweep. If you suspect buildup, call (855) 341-3461 and we’ll confirm it safely.
If your Covina flue needs relining, we use DuraFlex liner systems for structural relining and HeatShield for ceramic resurfacing of damaged flue interiors. The right fix depends on what we find on camera: cracked clay tile, spalling joints, or a flue that’s too far gone for resurfacing. We’ll recommend the specific fix for your flue and show you why. Call (855) 341-3461 for a free estimate.
If your Covina fireplace hasn’t been swept in years, or you’re seeing smoke back into the room, call Walnut Chimney at (855) 341-3461. We’ll book a sweep, show you what’s in your flue, and give you a straight answer about what needs work and what can safely wait. Free estimates. No surprises. Serving all of Covina, including 91722, 91723, and 91724.
