Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

We work in Walnut every week, and we know exactly what these homes look like inside the flue. A fireplace service visit with a camera inspection typically runs $189 to $279 in Walnut, and everything is quoted in writing before we start. Call (980) 580-8641 to schedule.

Why Emberly Chimney Cleaners Is Walnut’s Preferred Fireplace Services Company
Emberly Chimney Cleaners built its name on one practice: camera documentation before and after every job. Since 2009, we’ve completed more than 38,000 chimney inspections and cleanings, and every single one included a photo record the homeowner kept. That’s Clause 4 of the Haven Standard, and it’s non-negotiable for us. Walnut homeowners tend to research before they call, and we respect that. You’ll get a named technician, a text when they’re on the way, and a written scope before anything gets touched.
Our crews serve Walnut directly from the Los Angeles coordination office, so scheduling is straightforward and we’re typically on-site within a few days of your call. The homes along Grand Avenue, up toward the Puente Hills, and through the Snow Creek and Three Oaks neighborhoods all share similar chimney profiles, and our techs know what to look for on a 1978 tract home versus a 1985 custom build. Background-checked, uniformed technicians show up with the equipment to actually diagnose, not just guess.
Our Fireplace Services in Walnut
We handle the full range of fireplace work, but in Walnut, most of our calls fall into a handful of categories. Here’s what we see most often. Every one of these starts with a camera down the flue and a written price before work begins.
Gas Fireplace Service
Many Walnut homeowners have converted original wood-burning fireplaces to gas, or bought homes where the conversion was done years ago. Gas fireplaces need regular service too: burner cleaning, pilot assembly checks, glass gasket replacement, and venting inspection. A typical gas fireplace service in Walnut runs $149 to $249 depending on the unit and what’s been neglected. If you smell gas or the flame looks lazy and yellow, call before you use it again.
Wood Burning Fireplace
Wood burning fireplaces are still common in Walnut, especially in the larger homes along the hills. The real work here is creosote removal and firebox inspection. In Walnut’s inland climate, people burn infrequently and at low temperatures during cold snaps, which produces exactly the kind of incomplete combustion that leaves heavy creosote deposits. A wood burning fireplace cleaning and inspection typically runs $189 to $279 in Walnut. We document everything with the camera before we recommend anything beyond a sweep.
Fireplace Insert
Fireplace inserts, both gas and wood, are popular upgrades in Walnut homes where owners want actual heat output instead of just ambiance. We service existing inserts and install new ones in existing masonry or factory-built fireplaces. An insert service visit in Walnut typically runs $179 to $299 depending on what’s involved. We use Famco and Copperfield components where appropriate, and we’ll never recommend an insert without first verifying the existing flue can handle the venting requirements.
Damper Repair
Dampers fail in predictable ways on 40-plus-year-old Walnut fireplaces: rusted hinges, warped plates, broken chains or handles. A damper that won’t open or seal properly costs you heat in winter and lets air escape year-round. Damper repair or replacement in Walnut typically runs $129 to $349, depending on whether we’re repairing the existing damper, installing a top-sealing damper, or replacing the entire assembly. We’ll show you the condition on camera before we touch it.
BeforeAfterTrusted Brands We Service in Walnut
We stock and source materials from DuraFlex, HeatShield, and Copperfield through our buying network, which keeps prices honest for Walnut customers. That means faster turnaround on common fireplace components: dampers, caps, liners, and gas components. If your fireplace uses a specific manufacturer’s part, we’ll tell you what we’re ordering, what it costs, and when it arrives. No vague “parts are on order” without a date or a price. That’s Clause 1 of the Haven Standard: written price, written scope, written warranty before work starts.
Common Fireplace Services Problems We See in Walnut Homes
- Spalling clay flue tiles. Walnut’s 1970s and 1980s fireplaces were typically built with clay tile liners. After 40 to 50 years of thermal cycling, those tiles crack and flake, leaving gaps where heat and gases can reach the surrounding masonry structure. This isn’t a scare tactic; it’s what the camera shows us on a large share of first-time inspections in Walnut.
- Rusted or collapsed spark arrestors. Walnut sits against the Puente Hills in a Los Angeles County High Fire Hazard Severity Zone. Original steel spark arrestors from the 1970s and 1980s have rusted through or collapsed entirely on many homes, and on hillside-facing properties that’s a code enforcement issue, not just a maintenance annoyance.
- Backdrafting during Santa Ana wind events. Hillside homes along the Puente Hills edge catch dry, gusty Santa Ana winds that push down flues and force smoke back into living spaces. Homeowners often mistake this for a damper problem when the real issue is a damaged chimney cap, a blocked flue, or wind-driven debris packed into the smoke chamber.
- Creosote accumulation from short, low-temperature burns. Walnut’s cold snaps are real but brief, so people light fires for a few hours at a time. That produces the kind of low-temperature, incomplete combustion that leaves Class I and sometimes Class II creosote deposits. Class I is brushable; Class II is flaky and harder to remove; Class III is glaze and dangerous. We’ll tell you which you have and show you the footage.

FAQs - Fireplace Services in Walnut
Because they were built with clay tile liners, and clay tile doesn’t last forever. In Walnut’s housing stock, the original liners have been through four or five decades of heat cycling, and the mortar joints between tiles fail first. Once a joint opens up, heat and moisture get behind the tiles and the deterioration accelerates. We see spalling tiles and cracked mortar on a significant share of first-time inspections in Walnut homes from this era. The fix is either a HeatShield resurfacing or a DuraFlex stainless steel liner, and we’ll show you camera footage of the damage before we recommend either.
Yes. Walnut sits in a Los Angeles County High Fire Hazard Severity Zone, and LA County Fire enforces spark arrestor requirements on homes in that zone. Homes backing up to the Puente Hills slopes are subject to defensible-space inspections, and a missing or crushed spark arrestor on those properties is a citation risk. We get called to Walnut’s eastern and northern edges specifically to fix this before re-inspection. A new stainless steel cap with an integral spark arrestor typically runs $350 to $650 installed, and it clears the deficiency.
Santa Ana winds hit the Puente Hills edge hard, and they push down flues on hillside-facing homes. When that happens, smoke backs up into the house even if the damper is fully open. Homeowners often mistake this for a damper problem. It’s usually a damaged or missing chimney cap, a blocked flue from wind-driven debris, or both. We diagnose it with a camera and a draft reading, not a guess. Call (980) 580-8641 if your fireplace smokes during wind events; the fix is often less expensive than people assume.
You need it more than the person who burns every weekend. Infrequent, short-duration fires at low temperatures produce incomplete combustion, which leaves heavier creosote deposits than hot, sustained burns. In Walnut’s climate, that’s exactly the use pattern most fireplaces see. A chimney that’s used three times a year can build up more dangerous creosote than one used three times a week. The NFPA standard is an annual inspection regardless of usage, and we follow it. Clause 4 of the Haven Standard requires a documented photo record on every visit, so you’ll see what we see.
First-degree creosote is a fine, sooty powder that brushes off easily. Second-degree is flaky and requires more aggressive removal. Third-degree is a hard, glazed, tar-like coating that is highly combustible and requires chemical treatment plus mechanical removal. In Walnut, the low-temperature, short-burn pattern on many fireplaces tends to produce first- and second-degree deposits, but on hillside homes where Santa Ana winds cause backdrafting, we sometimes see third-degree forms quicker than expected because of incomplete combustion patterns. We’ll identify the class with the camera and tell you what it means before recommending any treatment. Call (980) 580-8641 for an exact assessment.
If you’ve got a fireplace in Walnut that hasn’t been looked at in years, the best time to have it inspected is before you light the first fire of the season. Call (980) 580-8641 and we’ll schedule a Level 2 camera inspection with a written report and a photo record you keep. No pressure, no upselling, just the footage and the facts.
