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 Orange, CA
Chimney repair in Orange usually means one of two jobs: rebuilding a cracked crown on a 1920s Craftsman near the Plaza, or replacing a rusted cap on a 1960s ranch off Chapman. Walnut Chimney has served Orange since 2017, and the work here splits cleanly between unlined historic brick and mid-century factory-built flues. Both need a technician who knows which material belongs where. Our crews carry Copperfield caps, HeatShield resurfacing compound, and DuraFlex liner systems, so when we open a flue and find damage, we can repair it that day instead of handing you a referral. Call (855) 341-3461 to get an Orange chimney looked at before burning season.
Why Orange Homes Are Different
Old Towne Orange is the largest intact turn-of-the-century historic district west of the Mississippi, and the Craftsman and Victorian homes surrounding the Plaza were built between roughly 1900 and 1930. Their original brick chimneys have no modern flue liner. The inside of the flue is raw masonry, often mortared with lime-based mix that has been eroding for a century. When we sweep a chimney on Maple or Orange Street, we are checking for missing mortar joints, spalling brick, and clearances to wood framing that were never up to any code because no code existed when the house went up. Exterior repairs near the Plaza can also trigger historic-preservation review, so the work needs to look right as well as function right.
The eastern and northern reaches of Orange, particularly around Chapman Avenue and the 92867 and 92868 ZIP codes, are a different animal entirely. Those are mid-century ranch tracts with factory-built metal fireboxes and pre-fab flues. Those systems fail differently: rusted caps, warped dampers, cracked refractory panels. The climate makes its own contribution. Orange gets long, dry stretches where fireplaces sit idle for months, then a few weeks of winter use that deposits a fresh layer of creosote over the old. Add Santa Ana wind and dry brush conditions, and a chimney that has not been inspected in three years is a measurable fire risk, not a vague one.
Styles & brands we work with





Our Main Orange Services
Most Orange homeowners call us for one of two things: a sweep on a fireplace that has not been used in years, or a dryer vent that takes two cycles to dry a load. Both are fire-safety issues, and both are covered in detail on their own pages.
Chimney Sweep in Orange
In Old Towne, a sweep is rarely just a sweep. The original unlined brick flues hold creosote differently than modern clay liners, and the long dry spells between fires mean deposits harden in stages. Our technicians remove the buildup and check the masonry at the same time, because in these homes the structural condition of the flue matters as much as the soot level. Homes in the 92865 and 92866 ZIPs, closer to the historic core, tend to need more careful interior work than the newer builds further east. Full details are on our Chimney Sweep in Orange page.

Dryer Vent Cleaning in Orange
Dryer vents in Orange homes run long in ranch layouts, and the lint that builds up inside is a leading cause of home fires, which the NFPA has documented for years. We treat dryer vent cleaning as a core safety service, not an add-on, and we can do it on the same visit as a chimney sweep. That way both fire hazards in the home get addressed in one trip. See our Dryer Vent Cleaning in Orange page for what the job involves and why it matters here.

Chimney Repair in Orange
Chimney repair in Orange comes down to age. A century-old unlined brick flue near the Plaza fails from the inside out, while a 60-year-old factory-built firebox off Tustin Avenue fails from the top down. The climate compounds both: years of heat cycling followed by long idle stretches, then Santa Ana winds that drive rain sideways into cracked crowns. Walnut Chimney handles the full range, and because we carry HeatShield, DuraFlex, and Copperfield materials on our trucks, most repairs get completed on the first visit. Our Chimney Repair service covers everything from a missing cap to a full flue resurfacing.
Chimney Cap Installation
Signs you need it
You can see daylight through the top of your flue, or birds and debris are getting in.
What it costs in Orange
Chimney cap installation in Orange typically runs $200 to $450 depending on flue size and cap material.
How we do it
We measure the flue opening, set the correct Copperfield or Gelco cap with the right screen mesh, and secure it so Santa Ana gusts cannot lift it off.
Chimney Cap Replacement
Signs you need it
The existing cap is rusted through, bent, or has mesh that is torn open enough for birds or embers to pass.
What it costs in Orange
Replacing a worn or rusted chimney cap in Orange costs between $250 and $500 including the new cap.
How we do it
We remove the old cap without damaging the crown, match the new cap to the flue dimensions, and fasten it with stainless hardware rated for Orange’s dry heat and wind.
Chimney Liner Installation
Signs you need it
Your flue has no liner at all, like most Old Towne originals, or the existing clay liner is cracked, flaking, or shifting.
What it costs in Orange
Chimney liner installation in Orange ranges from $900 to $2,500 depending on flue length, access, and whether we use a rigid or flexible system.
How we do it
We size the correct DuraFlex liner to the flue, feed it down from the top, connect it at the appliance, and insulate where clearance to framing is tight in older Orange homes.
Chimney Flashing Repair
Signs you need it
You see water stains on the ceiling near the chimney, or the metal flashing where the chimney meets the roof is pulling away or corroded.
What it costs in Orange
Chimney flashing repair in Orange typically falls between $350 and $800, with full replacement running higher if the roofline is steep.
How we do it
We remove the old flashing and sealant, install new step and counter flashing with the correct overlap, and seal the joint so wind-driven rain from the Santa Anas cannot push water under the shingles.
Chimney Crown Repair
Signs you need it
The concrete or mortar crown on top of the chimney is cracked, spalling, or missing chunks, letting water soak into the masonry below.
What it costs in Orange
Crown repair in Orange costs between $300 and $900, depending on whether we patch, resurface, or recast the entire crown.
How we do it
We clean out the damaged material, rebuild the crown with the proper overhang and drip edge, and finish it with a water-shedding surface that stops the freeze-thaw cycling Orange winters put on masonry.
What Chimney Repair Costs in Orange
| Item | Typical range in Orange |
|---|---|
| Chimney cap installation | $200 – $450 |
| Chimney cap replacement | $250 – $500 |
| Chimney liner installation | $900 – $2,500 |
| Chimney flashing repair | $350 – $800 |
| Chimney crown repair | $300 – $900 |
Two things push prices up in Orange. The first is working on century-old masonry in Old Towne, where we often discover hidden clearance problems or missing liners behind the soot. The second is access: steep rooflines on some Craftsman Victorians and tight side yards on mid-century lots both add labor. Walnut Chimney gives a flat price sweep before we book, so the quote you approve is what you pay.
Is my old Orange chimney safe to repair, or do I need a full rebuild?
Most unlined brick chimneys in Old Towne can be made safe by resurfacing the flue with HeatShield rather than rebuilding from scratch. We assess the brick, mortar, and clearances during the inspection, then tell you plainly whether repair is enough. When the masonry itself is sound, a liner or resurfacing job restores safe function without the cost of demolition. Call (855) 341-3461 and we will show you the camera evidence before quoting anything.
Do I need a permit for chimney repair in Orange?
Simple repairs like cap replacement or crown patching generally do not require a permit in Orange. Larger liner installations or structural rebuilds near the Plaza may need sign-off, and historic review applies to exterior work in Old Towne’s protected district. We know which jobs trigger review and can tell you on the inspection call. Our repair quote includes that local reality, not a surprise after the fact.
Brands We Service in Orange
Walnut Chimney works with DuraFlex, HeatShield, and Copperfield systems, keeping common components on the truck for Orange jobs. We stock caps, liner sections, and resurfacing compound locally, so a standard repair does not wait on a parts order. Learn more about our brands and the warranty coverage each one carries.

What Orange Customers Say
"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."
— Luis Garcia"Creosote buildup was worse than I realized. He measured it, showed me the glazing on the flue with the camera, and was honest that we were closer to a chimney fire than I wanted to hear."
— Renee Mercer"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."
— Justin Nguyen
