We know Hillsborough’s homes: tall masonry stacks, multiple flues, and steep rooflines that make a proper cleaning more than a brush-on-a-rope job.

Hank Delano runs our crews, and every technician arrives background-checked and in uniform. We don’t dispatch a salesperson with a truck. We dispatch a sweep who can explain what they’re seeing, show you the camera footage, and tell you straight what needs work now and what can wait.

Why Flint Chimney Sweep Is Hillsborough’s Preferred Chimney Sweep Company

Hillsborough homeowners tend to ask the same three things when they call us: what’s the flat price, who exactly is coming to the house, and what happens if the repair doesn’t hold. Those are fair questions, and we answer all three before the appointment is booked. Every job gets a written price before work begins, with the full Chimney Sweep scope laid out in plain English. The number on that paper is the number you pay.

We’ve been at this since 2002 as part of the Garrison Partners family of independently owned chimney companies. That matters for one practical reason: we operate under The Garrison Standard, which means the same written guarantee terms follow us everywhere we work. If a covered repair fails within one year, we return at no charge. No re-inspection fee, no argument.

Hank Delano has overseen work on chimneys from Eucalyptus Hill to Ralston Avenue and every winding street in between. Our techs understand what those deep Hillsborough lots mean for chimney life: oak and madrone debris piling into spark arrestors, wildlife trying to make an offseason home inside the cap, and moisture working into crowns that sit exposed above the tree line. We plan the job around the actual stack in front of us, not a generic chimney in a textbook.

Gas Fireplace Cleaning in Hillsborough

Gas Fireplace Cleaning in Hillsborough homes is a different job from a traditional firewood sweep, and it’s one we handle regularly across the area. Gas units don’t produce creosote, but they do accumulate fine soot, dust, pet hair, and sometimes mineral residue from the gas line itself. In Hillsborough’s older hillside estates, we often find gas fireplace units that have been installed into original masonry fireboxes, which means the venting runs through a clay tile flue that still needs periodic inspection even though the fuel source has changed.

A gas fireplace cleaning in Hillsborough typically runs $149 – $219 depending on the unit. That includes the glass removal, cleaning the firebox and log set, clearing the burner ports, and checking the pilot assembly. We’ll also run a quick visual on the entire flue path.

What the Cleaning Includes

We disassemble the glass front, pull the log set out carefully, and clean each burner port so the flame pattern returns to even blue instead of uneven yellow. The pilot tube gets cleared of debris. If the unit burns a yellow or orange flame after cleaning, that’s a ventilation or gas pressure issue and we’ll tell you what an HVAC or gas technician should look at next.

When a Gas Fireplace Needs Attention

If you use the gas fireplace more than a few times a week during Hillsborough’s damp winters, an annual cleaning is reasonable. If it’s a decorative unit that runs twice a year, every two years is fine. The real issue with gas units isn’t soot. It’s blockage in the venting or a cracked heat exchanger that lets carbon monoxide leak into the living space. A camera inspection catches that.

Chimney Maintenance in Hillsborough

Chimney Maintenance in Hillsborough is the part most homeowners skip, and it’s the part that saves real money in the long run. Maintenance means more than sweeping. It means catching a spalling brick crown before water gets behind the chase, re-caulking a top plate that’s starting to separate, and keeping the damper moving freely. On Hillsborough’s older estates with tall, exposed stacks, those small repairs buy years of service life.

A maintenance visit in Hillsborough typically runs $129 – $199 when we’re already on-site for a sweep, and $199 – $299 as a standalone call. We always provide the written price before the work starts.

What We Check on Every Maintenance Visit

We inspect the crown for hairline cracks, check the flashing where the chimney meets the roofline, test the damper operation, and look for any rust on the cap or spark arrestor. The camera goes up if any single check shows something we can’t see clearly from the top or firebox. A maintenance visit is not a formal inspection, but it catches the same early-warning failures.

What Can Actually Wait

Hairline cracks in a wash get worse with every freeze-thaw cycle, so a crown sealing job in September beats a water-damaged chase in March. Hillsborough’s heavy winter rain and occasional morning frost make this more urgent than a homeowner in a drier climate might expect. But here’s the straight answer: if the flue was swept within 18 months, you haven’t burned more than a cord since, and there’s no water staining on the ceiling, you can put off maintenance until the next burning season. We’ll tell you that plainly, even if it means we don’t book the work.

Trusted Brands We Service in Hillsborough

When a Hillsborough chimney needs a liner or repair component, we spec materials by the job, not by what’s left on the truck. We work with DuraFlex stainless steel liners for flue relining and upgrades, HeatShield for masonry flue restoration when the liner can be repaired rather than replaced, and Olympia Chimney and Famco caps and dampers where a crown-level fix is needed. We keep common parts stocked for Hillsborough jobs since the multi-flue stacks here mean a three-flue cap isn’t a special order, it’s a Tuesday. If we don’t have the exact part on the truck, we tell you before you’ve paid anything and we give you a date on the written quote.

Common Chimney Sweep Problems We See in Hillsborough Homes

• Glazed creosote on tall multi-flue stacks. Hillsborough’s larger homes often have three or more flues running through a single masonry stack. We routinely find second-degree glazed creosote above the smoke chamber because the flue is too tall for a standard brush to clear effectively. A camera tells us what’s actually still caked on.
• Oak, madrone, and leaf debris in the cap and spark arrestor. The deep lot setbacks and heavy canopy in neighborhoods off Ralston and Crystal Springs mean caps fill with leaves, twigs, and sometimes whole bird nests between seasons. This restricts draft and pushes smoke back into the house.
• Cracked crowns on exposed chimneys. A crown that takes direct weather all winter cracks eventually. Water works its way into the chase, and by the time you see plaster damage near the fireplace, the rust has already started on metal components.
• Wildlife entry through damaged side screens. We’ve pulled raccoon and squirrel nesting material out of chimneys in the Chateau Drive and Skyfarm areas more times than we can count. If you’ve heard scratching behind the firebox surround, the cap screen is likely compromised and needs a proper cap replacement.
