Pricing & Estimates
How much does chimney cleaning service cost?
Chimney cleaning cost depends on the type of chimney, how much creosote has built up, and whether the flue is straight or has an offset.
A standard sweep on a clear, accessible flue runs less than a heavily glazed one that needs extra passes. We don’t post flat prices because quoting blind leads to surprises, and we’d rather look first. When we arrive, we inspect the firebox, flue, damper, and cap, then give you an upfront number before any work starts. Estimates for a sweep are free. If the inspection turns up a repair need, we explain what and why, and you decide. Call (855) 341-3461 for an exact quote.
Do you offer free estimates?
Yes, we offer free estimates on chimney sweeping and on the repairs we diagnose during a visit.
For a sweep, the estimate covers the full scope of work. For repair work, we inspect and explain what we found before quoting: a cracked crown, a damaged flue tile, a loose cap. You get the estimate with no obligation. We don’t pressure you into a decision on the spot, and we don’t add line items you didn’t approve. A clean chimney is a measurable thing, and so is a fair quote.
Why don’t you list prices on this page?
We don’t list flat prices because two chimneys of the same size can need very different amounts of work.
A prefab fireplace with a straight run sweeps quickly. A masonry chimney with heavy creosote and a warped damper takes longer and may need repair work before it’s safe to use. Posting a single number would mislead half the people reading it. We quote after inspection, in writing, before we start.
Service & Scheduling
Do you offer emergency chimney cleaning service?
We handle urgent chimney and vent calls, including situations where you have a strong creosote smell, visible smoke backing into the room, or an animal stuck in the flue.
Some of these are true safety issues and some aren’t, so call and describe what you’re seeing. We’ll tell you honestly whether it can wait for a scheduled visit or needs attention sooner. If we can get to you quickly, we will. For a blocked flue or a fire risk, don’t burn anything in the fireplace until it’s inspected.
How fast can you respond?
Response time depends on the season and your location, and we’ll give you a realistic window when you call.
Fall and winter are our busiest months because that’s when people start using their fireplaces again. We schedule in order of need, and genuine safety issues move to the front. When you call (855) 341-3461, we’ll tell you the next available slot instead of a vague promise.
What areas do you serve?
We serve homeowners across the Garden Grove area and surrounding communities.
If you’re not sure whether you’re in our service area, call and give us your city or ZIP code. We’ll confirm before you book. We don’t send technicians to areas where we can’t show up reliably.
Do you clean dryer vents too?
Yes. Dryer vent cleaning is one of our three core services, not an add-on we hand off to someone else.
The NFPA cites dryers as a leading cause of home fires, and lint buildup is the main culprit. We clean the full vent run from the dryer connection to the exterior cap, and we check for crushed or disconnected ducting while we’re in there. If your dryer takes two cycles to dry a load or the outside vent flap barely moves, it’s worth a look.
Can you sweep my chimney and clean my dryer vent in the same visit?
Yes. We combine chimney sweeping and dryer vent cleaning in a single appointment whenever scheduling allows.
Both hazards live in the same house and many homeowners forget one while focusing on the other. Handling both in one visit means one trip, one technician, and both fire risks addressed. Just tell us when you book that you want both, so we allot the right amount of time.
Licensing & Trust
Are you licensed and insured?
Yes, Walnut Chimney is a licensed and insured chimney and vent service company.
We carry the insurance that protects your home while we work in it. If you’d like documentation before your appointment, ask us and we’ll send it. You should expect any company working on your chimney to show proof before they start, and we’re glad to.
Do you guarantee your work?
Yes, we stand behind our work. If something we serviced or repaired isn’t right, call us and we’ll address it.
We diagnose before we quote, and we don’t hand back a chimney we consider unsafe. If a repair needs a follow-up visit to make right, we take care of it. Our goal is that you understand what was done and why, and that the result holds up through the burning season.
What payment methods do you accept?
We accept common payment methods including major credit cards, checks, and cash.
Payment is due when the work is complete. If you’re scheduling a larger repair, ask about payment details when you book. We’ll confirm what we accept for your specific job so there’s no confusion on the day of the visit.
Who works on my chimney?
Our own technicians do the work. We don’t subcontract chimney sweeps or repairs to outside crews.
That matters because the person sweeping your flue is also the person who spots a cracked tile or a failing crown, and the same company handles the fix. There’s no hand-off to a separate contractor, no gap between what the sweep found and what the repair crew was told.
Specific Services
Do you handle chimney cleaning and sweeping?
Yes, chimney sweeping is our most-requested service. We remove creosote, soot, and debris from the flue and firebox.
We use drop cloths and a sealed HEPA vacuum so ash stays in the flue and out of your living room. After the sweep we inspect the damper, smoke chamber, and cap and report what we find. If you’re due, you can read more about a Chimney Sweep in Walnut and what a thorough visit covers.
How often should I have my chimney swept?
Most chimneys should be swept once a year, and more often if you burn frequently or use green or soft wood.
The National Fire Protection Association recommends an annual inspection, and a sweep whenever there’s a meaningful buildup of creosote. Creosote comes in stages, from light soot to a glazed, tar-like coating that’s harder to remove and more combustible. If you burn several cords a season, a yearly sweep may not be enough. When you’re not sure, an inspection settles it.
Do you handle chimney repair?
Yes, chimney repair is one of our three core services, and we use professional-grade materials matched to each job.
We use DuraFlex flexible liner systems for relining flues, HeatShield ceramic resurfacing to restore damaged flue interiors, and Gelco and Famco components for caps, covers, and venting. Olympia Chimney and Copperfield round out the material lineup for liners and related parts. That means we pick the right material for the repair instead of forcing one brand to fit every problem. Most basic sweep companies can’t offer HeatShield resurfacing at all, since it’s a repair-level capability. We repair what we find, from the firebox to the cap.
What chimney repairs do you handle most?
The most common repairs are flue relining, crown and cap replacement, damper repair, and masonry repointing.
Cracked crowns let water in. Missing or damaged caps let rain, birds, and debris down the flue. Deteriorated flue tiles create gaps that let heat and gases reach combustible parts of the house. Each of these has a specific fix:
- Flue relining: A DuraFlex liner restores a safe, code-compliant path for smoke and gases.
- Flue resurfacing: HeatShield ceramic material repairs the interior without a full rebuild.
- Crown repair or rebuild: Seals the top of the chimney against water intrusion.
- Cap replacement: Gelco and Famco caps keep weather and animals out while allowing proper draft.
Not every problem is visible from the ground, which is why we inspect before we quote. If you suspect a cap issue, call us and we’ll take a look.
What’s the repair process if my flue needs relining?
A reline is a defined sequence, and we walk you through each step before we start.
It’s a repair, not a patch, so we don’t skip steps to save time.
- Inspect the flue. We check the interior for cracking, gaps, and deterioration.
- Size the liner. We measure the flue and confirm the correct appliance venting requirements.
- Prep the interior. We clean and, if needed, resurface with HeatShield before installing anything.
- Install the liner. We fit the DuraFlex system and connect it at the top and bottom.
- Verify and review. We confirm draft and clearances, then walk you through what was done.
The same brand-matching logic applies whether you need a full liner or a single cap, which is why we keep multiple professional brands on hand rather than one.
Do you handle fireplace services?
Yes, we service the fireplace as part of chimney work: sweeping the firebox, checking the damper, and inspecting the smoke chamber.
We focus on fire safety and function. When we visit for a sweep, we inspect the parts you rely on every time you light a fire and tell you what condition they’re in. If something’s worn, we explain the repair. If you’re not sure your fireplace is ready for the season, a visit answers that.
Do you handle chimney caps and crowns?
Yes, we repair and replace chimney caps and crowns using professional-grade components.
The cap keeps out rain, birds, and debris. The crown seals the top of the chimney against water. When either fails, water finds its way into the masonry and the damage spreads. We source caps and covers from Gelco and Famco so the replacement actually fits your chimney. If you’ve noticed a crumbling crown or a missing cap, call us at (855) 341-3461 for an estimate.
Does my chimney really need an annual inspection?
Yes. An annual inspection catches problems early, before they turn into expensive repairs or safety hazards.
Creosote buildup, cracked flue tiles, a loose damper, or a failing cap all start small. A yearly look keeps you ahead of them. It’s also the honest way to know how often your particular chimney needs sweeping, since burn habits and wood type change how fast creosote collects.
Why Choose Walnut Chimney
Why should I choose one company for sweeping and repairs instead of two?
One company means the person who finds a problem is the person who fixes it, which removes the gap between a sweep and a repair.
We sweep, repair, and clean dryer vents under one call. The technician who sees a cracked crown during your sweep can quote and handle the repair instead of writing a note and handing it to a separate contractor. That removes the game of telephone and the waits between multiple companies. Professional-grade materials, including DuraFlex and HeatShield, are on hand because we do the repairs ourselves.
What brands do you work with?
We use DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield.
Each one covers a different part of the job. HeatShield handles flue resurfacing. DuraFlex and Olympia provide flexible liner systems. Gelco and Famco supply caps, covers, and venting components, and Copperfield rounds out the lineup. Naming the brands matters because it shows we choose the right material for the repair rather than forcing one product on every chimney.
Is dryer vent cleaning part of the service, or separate?
It’s a core service, not a side offering. We treat dryer vent cleaning as part of whole-home fire safety.
Lint accumulates in the duct run and the exterior cap, and it’s a documented fire risk. Many homeowners think about the chimney and forget the dryer vent, even though both are listed as fire hazards. Combining chimney sweeping, repair, and vent cleaning under one company lets us address both hazards in the same call.
Still Have Questions?
If you didn’t find your answer here, we’d rather talk it through than have you guess. Whether it’s a creosote smell, a cap you’re not sure about, or a dryer that takes two cycles to dry a load, call us and we’ll tell you what we think the visit needs. Call (855) 341-3461 for a free estimate, and we’ll schedule a time that works for you.
