Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Trusted Chimney Sweep for Sunnyvale Homeowners
A chimney sweep in Sunnyvale removes the creosote and soot that build up inside your flue with every wood fire, and that residue is the reason chimney fires start. We clean fireplaces and wood stoves throughout Santa Clara County, and we also inspect the flue liner, crown, cap, and damper so you know exactly what condition the system is in before burning season. Kurt Jessup leads our team, and he built the company around a straightforward idea: inspect, explain, then repair. No pressure, no mystery. Call (833) 593-7116. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Chimney Sweep Services
Chimney Sweep Services cover the mechanical removal of creosote, soot, and debris from the interior of your flue, plus a visual inspection of the chimney’s accessible components. We recommend a sweep before the first fire of fall and any time you notice a strong campfire smell inside the house or black flakes dropping into the firebox. A standard sweep in Sunnyvale typically runs $180 to $340 depending on flue height, accessibility, and how much buildup has accumulated since the last cleaning. The written estimate we provide before work begins sets the final price.
Wood-Burning Fireplace Sweep
This is the classic job: brushes sized to your flue, drop cloths protecting the hearth and floor, and a HEPA-filtered vacuum running throughout. We clean from the top or bottom depending on roof access, and we always check the smoke chamber where creosote tends to collect unnoticed.

Wood Stove Flue Cleaning
Wood stoves burn hotter and cleaner than open fireplaces, but the connector pipe and flue still need attention every year. We remove the baffle, clean the connector, and sweep the full liner so the stove drafts correctly and burns efficiently.

Chimney Cleaning
Chimney Cleaning is the physical removal of combustion byproducts from the flue, smoke shelf, damper, and firebox. Glazed creosote, the tar-like third-stage buildup, can’t be brushed out with standard methods and often requires chemical treatment or mechanical removal with specialized tools. Our team handles all three stages of creosote, and we document what we remove so you can see it. Typical chimney cleaning in Sunnyvale costs $180 to $340, and the estimate we give before starting is the price you pay.
Creosote Removal
Creosote forms when wood smoke condenses against cooler flue walls. Stage one is flaky and brushes out easily. Stage three is glossy and hardened, and it’s the form most likely to fuel a chimney fire.
Smoke Chamber Cleaning
The smoke chamber sits between the firebox and the flue, and it’s where a surprising amount of debris gets trapped. If your fireplace has a smoky smell even when it’s cold outside, this is often the cause. We clean it during every sweep.
Fireplace Cleaning
Fireplace Cleaning addresses the firebox itself: removing ash, charred wood remnants, and the soot that blackens the brick or refractory panels. It’s done alongside a full flue sweep because a clean firebox with a dirty flue still leaves you exposed to chimney fire risk. Homeowners in Sunnyvale usually pay $180 to $340 for a combined fireplace cleaning and chimney sweep, depending on the level of buildup and the size of the firebox.
Firebox Ash Removal
Ash should be removed regularly, but never while the fireplace is hot or when live coals are present. We vacuum, bag, and remove ash so your hearth is ready for the next fire, and we check the firebrick for cracks while we’re there.
Glass Door Cleaning
Wood-burning fireplace doors collect a cloudy film that glass cleaner won’t remove. We use a specialized cleaner that lifts combustion haze so you can actually enjoy the fire you’re paying to burn.
Chimney Services
Chimney Services encompass everything beyond the basic sweep: inspections, cap and crown repair, damper work, leak diagnosis, and full liner repairs. When we find cracked flue tiles during a sweep, we can often restore the flue with HeatShield rather than recommending a full reline, which saves Sunnyvale homeowners a significant amount of money. Depending on the scope, chimney services in this area typically run from $180 for a basic sweep and inspection up to several thousand for major liner or masonry work. Every job gets a written estimate before we begin.
Chimney Cap and Crown Repair
The crown is the concrete slab at the top of the chimney, and when it cracks, water gets into the masonry. We repair crowns with proper expansion joints and install caps that keep rain, birds, and debris out of the flue.

Flue Liner Inspection and Repair
Cracked clay tiles or a missing section of liner means heat and gases can reach combustible framing. We camera-inspect the flue and show you the footage. If the damage is moderate, HeatShield resurfacing can often restore the liner’s integrity.
Chimney Sweep Certified
Chimney Sweep Certified means a technician has completed formal training and demonstrated competence in safe flue cleaning and inspection methods. Certification matters because improper sweeping damages liners and misses the glazed creosote that standard brushes can’t remove. Our lead, Kurt Jessup, has spent more than a dozen years in the trade, and every inspection follows a consistent checklist so nothing gets skipped. A certified chimney sweep in Sunnyvale generally charges $180 to $340 for a standard cleaning and inspection, with the price confirmed in the written estimate.
Why Certification Matters
An untrained sweep can scar a clay liner with the wrong brush or leave the chimney looking clean while creosote hides in the smoke chamber. Certified training covers the full system, not just what’s visible from the roof.
What We Check on Every Job
Flue liner condition, smoke shelf accumulation, damper operation, crown cracks, cap installation, and clearances to combustibles. We photograph or video what we find so you’re never asked to take our word for it.
Gas Fireplace Cleaning
Gas Fireplace Cleaning addresses the soot, dust, and ceramic log deterioration that affect gas-burning units even though they produce far less residue than wood fires. Gas fireplaces don’t create creosote, which means they don’t need the same frequency of sweeping, but the logs, burner, and pilot assembly still need annual attention. A gas fireplace cleaning in Sunnyvale typically runs $120 to $250 depending on whether the unit is direct-vent, B-vent, or ventless. We set the final price in the written estimate before work starts.
Ceramic Log and Burner Cleaning
Gas logs develop a white film that dulls their appearance and can eventually clog the burner ports. We remove, clean, and reposition the logs, then verify the burner flame pattern is even and blue, not yellow and lazy.
Venting System Check
Even gas fireplaces need a clear vent path. We inspect the vent run for blockages, corrosion, or improper connections that could send carbon monoxide back into the living space.
Chimney Maintenance
Chimney Maintenance is the routine upkeep that prevents expensive repairs later: annual sweeps, seasonal inspections, cap and crown touch-ups, and damper adjustments. A well-maintained chimney in Sunnyvale’s mild climate still needs attention every year because creosote accumulates regardless of how cold the winters get. Budget $180 to $340 per year for a standard maintenance visit, though repairs found during the visit get their own estimate. Staying ahead of problems costs far less than emergency liner replacement.
Annual Inspection
Every chimney should be inspected at least once per year, even in a mild climate. We watch for liner cracks, water intrusion at the crown, and wildlife nesting. Sunnyvale attics and chimneys attract birds and squirrels, and a blocked flue is a carbon monoxide risk.
Seasonal Preparation
Before the first chilly night, we sweep the flue, test the damper, check the smoke shelf, and make sure your firebox is free of debris. That way the first fire of the season is a warm one, not a smoky one.
Brands We Service
We work with professional-grade components from manufacturers that certified chimney engineers specify, not anonymous hardware-store substitutes. DuraFlex flexible liner systems are one we install regularly, especially in chimneys with offsets or unusual geometry where a rigid liner would require major masonry work. The flexibility lets us adapt the liner to the actual path of your flue rather than trying to force a one-size solution.
HeatShield is another material we handle in-house, and it gives Sunnyvale homeowners a meaningful alternative to full relining. When flue tiles show cracking but the structure is still sound, we apply HeatShield to resurface and seal the damaged sections. We also work with Olympia Chimney, Famco, and Copperfield components in cap, crown, and venting repairs. Whether you have a chimney that runs on these brands or any other make, we can help.

AfterSigns You Need a Pro Right Now
- Strong smoky smell with no fire burning. This often means creosote or debris is trapped in the smoke chamber and the chimney isn’t drafting correctly. It’s also a sign moisture has gotten into the flue and is interacting with the creosote.
- Black flakes dropping into the firebox. Those flakes are pieces of creosote detaching from the flue walls, which means enough has built up to become a chimney fire hazard.
- Slow-burning fires and visible smoke in the room. When smoke can’t exit the chimney properly, it rolls back into the living space, which points to a blockage or an undersized flue that needs a professional look.
- Water staining on the ceiling or walls around the chimney. A cracked crown or flashing problem lets rain into the chase, and water plus masonry equals long-term structural damage.
- Animal sounds or nesting material visible at the top of the chimney. Birds, squirrels, and raccoons can block a flue completely, which sends carbon monoxide back into the house. Call us to inspect and install a proper cap.
Our Process, Step by Step
1. We schedule the call. When you phone (833) 593-7116, we answer 24/7. We ask about your fireplace or stove, when it was last swept, and what you’ve noticed inside the house.
2. We inspect before we sweep. Every job starts with a visual check of the firebox, damper, flue, cap, and crown. We’re looking for damage that could turn a routine cleaning into a bigger problem if we swept right over it.
3. We sweep and vacuum. Brushes sized to your exact flue remove creosote and soot, while a HEPA-filtered vacuum runs continuously. Drop cloths protect the hearth and surrounding floor. We clean the smoke chamber too, not just the flue.
4. We show you what we found. Camera inspections document the flue’s condition after sweeping. If we recommend repairs, we show you the footage and explain what it means. Nothing gets recommended without evidence you can see.
5. We quote and schedule repairs only if you want them. The estimate for any follow-up work is written, itemized, and pressure-free. If the chimney is clean and sound, we say so and recommend a next inspection date.
How Much Does Chimney Sweep Cost in Sunnyvale?
A typical chimney sweep in Sunnyvale runs $180 to $340, with the final number depending on flue height, roof pitch, the amount of creosote present, and whether the home has one fireplace or several. A simple single-story home with a straight flue usually falls at the lower end of that range. A two-story chimney with a steep roof pitch and heavy stage-two or stage-three creosote will land higher.
What affects the price most is the condition of the flue. If we discover cracked tiles or a failing liner during the sweep, the repair work is quoted separately, and you get camera evidence before any recommendation is made. Some companies quote a low sweep price and then pile on repair estimates. We’d rather show you the footage and let the chimney speak for itself. The free estimate includes the inspection, the sweep price in writing, and any repair recommendations with line-item costs, so you’re never surprised.
