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 Covina, CA
Sherwood Chimney Sweep handles chimney repair, sweeping, and dryer vent work throughout Covina’s 91722, 91723, and 91724 ZIP codes. Most of the chimneys we inspect here belong to homes built between the 1950s and 1970s, which means we’re usually looking at original clay tile liners and mortar crowns that have spent five or six decades under San Gabriel Valley sun. When those crowns crack and those liners spall, the fix is structural, not cosmetic. Call (833) 589-8498 if you suspect your Covina chimney has been quietly falling apart.
Why Covina Homes Are Different
Covina’s housing stock skews heavily toward post-WWII and 1960s-70s single-story tract homes, most of them stucco on slab foundations with the original masonry fireplace still in place. Those fireplaces were built with clay tile flue liners, and in many Covina homes those liners have never been touched. Fifty years of thermal cycling does real work on clay tile – sections crack, mortar joints between tiles wash out, and the liner loses its seal. We see it constantly in the older blocks off Citrus Avenue and the streets around Covina Park and Charter Oak.
The climate makes it worse. Covina gets hot, dry summers where temperatures push past 100 degrees, then long stretches of mild, mostly rainless weather. A chimney that sits unused for two or three years accumulates nesting debris from birds and squirrels, and whatever creosote is left from the last fire hardens into a glaze that’s difficult to remove with standard brushes. When rain does come, it finds every crown crack and mortar void the dry season opened up. Homeowners here often light a fire for the first time in years on a cold December night without realizing what’s inside the flue. That’s the call we get most during Covina’s brief winter.
Styles & brands we work with
Our Main Covina Services
Two services generate most of our Covina calls: the annual safety sweep on fireplaces that have sat dormant, and dryer vent cleaning in those same tract homes where the vent runs long and gets forgotten. Each is covered in more detail on its own Covina page.
Chimney Sweep in Covina
A thorough sweep in Covina usually reveals more than creosote. Because so many fireplaces here sit unused for years at a time, our technicians regularly pull bird nesting, squirrel debris, and hardened glaze out of flues in 91722, 91723, and 91724. We remove what’s there, flag any cracks or spalling we find in the liner, and give you a straight answer about whether the chimney is safe to burn. If you’ve been in your Covina home a few years and have never had the fireplace inspected, start with a Chimney Sweep in Covina.
Dryer Vent Cleaning in Covina
Most Covina tract homes route the dryer vent through the wall or up through the attic with a run that’s longer than code would permit today. Lint packs into those runs over time, and that lint is the leading cause of household dryer fires. We treat dryer vent cleaning as fire prevention work, not a side job. Our team pulls the accumulated lint, checks the exterior termination, and tells you if the vent itself should be replaced. Details are on the Dryer Vent Cleaning in Covina page.

Chimney Repair in Covina
Chimney repair in Covina is usually about restoring a mid-century masonry fireplace that has outlived its original components. Homes built in the 1950s through 1970s across 91722, 91723, and 91724 were fitted with clay tile liners that begin cracking after enough years of thermal stress, and the long hot summers here dry out the crown mortar above them. When a homeowner finally calls us after years of the fireplace sitting idle, the most common finding is a crown cracked open by heat and a flue liner that has lost structural integrity. That’s where our repair work starts, and it’s why we approach every job as though we may be rebuilding part of the fireplace, not just cleaning it. You can learn more about the full scope of what we handle on our Chimney Repair page.
Chimney Crown Repair
Signs you need it
Hairline cracks or missing chunks across the top of your chimney, water pooling inside the flue after rain, or crumbling mortar pieces on the roof below the chimney point to crown failure.
What it costs in Covina
Chimney crown repair in Covina typically runs $350 – $950, depending on how much of the crown is compromised and whether we need to rebuild it from scratch rather than patch.
How we do it
We remove the deteriorated crown surface, pack and seal the cracked areas, and apply a proper repair material that slopes water away from the flue instead of letting it sit.
Chimney Liner Installation
Signs you need it
If a sweep finds cracked or missing clay tile pieces in your Covina chimney, or if you have a hygrometer reading showing moisture passing through the flue, the liner may need replacement.
What it costs in Covina
In Covina, chimney liner installation and replacement commonly falls between $2,900 and $7,000, with the spread driven by flue length, access, and whether we’re also repairing the surrounding masonry.
How we do it
We size a liner to the flue, run it down from the top, connect it properly at the appliance, and insulate where needed so the whole system drafts correctly and safely.
Chimney Flashing Repair
Signs you need it
Water staining on the ceiling near the fireplace, damp drywall around the chimney chase, or visible gaps between the flashing and the chimney stack mean the flashing has failed.
What it costs in Covina
Chimney flashing repair in Covina is typically $450 – $1,400 depending on whether the issue is a reseal or a full replacement with new metal.
How we do it
We pull the old flashing, inspect the roofline intersection, install new step or continuous flashing as the profile demands, and seal everything with a roofing-grade sealant.
What Chimney Repair Costs in Covina
| Item | Typical range in Covina |
|---|---|
| Chimney crown repair | $350 – $950 |
| Chimney flashing repair | $450 – $1,400 |
| Chimney liner installation | $2,900 – $7,000 |
How long does chimney repair take in Covina?
Most crown and flashing repairs are done in a single visit, usually four to six hours on site. Liner installation takes a bit longer; we quote that as a one-day job unless the access is unusually tight, which does happen with some Covina tract-home roofs.
Do I need a permit for chimney repair in Covina?
Routine repairs like crown patching, flashing work, and liner installation generally move forward without a city permit in Covina. If a project expands into rebuilding the firebox or full masonry reconstruction, the City of Covina may want it permitted, and we’ll tell you before starting. Call (833) 589-8498 to talk through your specific situation.

The products we install across Covina come from the same professional trade supply chain used by certified chimney engineers nationwide.

What pushes a Covina price toward the top of each range is access; many of our local jobs involve single-story tract homes with roofs that are easy to walk, but some of the older blocks have steep pitches or chimney stacks that require more involved setup. The other factor is condition: a liner that comes out in pieces takes longer to remove, and a crown that crumbles as we open it up needs more material than the initial estimate assumed. Sherwood Chimney Sweep quotes a flat price before the sweep begins and sticks to it unless we uncover something that changes the scope, and we show you what we found before any additional work is approved.

FAQs About Chimney Company in Covina
We typically schedule Covina appointments within two to four business days. For homeowners who want a fireplace inspected before the first cold snap of the year, we recommend calling a week or two before you plan to use it, because October and November fill up quickly here. Call (833) 589-8498 to check current availability.
Yes. We cover 91722, 91723, and 91724 without added travel fees. Covina is geographically compact, but some of the hillside streets add a few minutes to the route, which we account for when we schedule the day.
Yes, and in Covina’s climate, it is actually more important. The long hot summers crack crown mortar while the fireplace sits idle, and birds and rodents build nests in flues that never see fire. A quick inspection before you light your first fire in years is cheap insurance. Call (833) 589-8498 for a free estimate.

What Covina Customers Say
"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
— Jodi Parker"Level two inspection before we bought the house. The report was detailed enough to use as a negotiating point and he explained every photo in it."
— Ruben Flores"Thorough sweep and a clear report. He was running late from the job before and arrived near the end of the window, though he did call to warn me."
— Nabil Saleh
