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 Danville, CA
Danville chimney work leans heavily toward inspection and documentation, especially for the 1980s-2000s executive homes along Diablo Road and the Blackhawk corridor. We spend more time proving gas fireplaces and inserts were vented correctly than scraping creosote off flue walls. If you’re selling, insuring, or just bought a home with a masonry or factory-built fireplace, call (833) 736-8208. We answer 24/7, and the estimate is free.
Why Danville Homes Are Different
Danville sits in the San Ramon Valley with hot, dry summers and mild winters. Chimneys idle for months, gathering creosote, bird nests, and the occasional squirrel stash, then get fired up on the first cool evening in October. The dry, breezy late-summer pattern also means wildfire embers are a real concern, so caps and spark arrestors matter more here than in foggy parts of the Bay Area.
The housing stock drives most of our Danville work. Large 1970s-2000s luxury and executive homes dominate, many with tall multi-flue chimneys that are genuinely difficult to reach safely. In Blackhawk and along Diablo Road, we routinely find factory-built fireplaces where the chase cover has leaked into the attic, turning what the homeowner thought was a simple sweep into a water-intrusion repair. The big inventory is not older housing; it’s gas inserts installed decades ago in affluent homes that now change hands quickly. Pre-sale and insurance inspections demand documentation, not just a brush through the flue.

Our Main Danville Services
Most Danville homeowners call us for two things: a documented sweep before a sale or the start of burning season, and dryer vent work they’ve been putting off. Both deserve a proper look, not a checkbox.
Chimney Sweep in Danville
A thorough Chimney Sweep in Danville means more than running a brush up the flue. We inspect the liner, damper, cap, and firebox, and we document what we find, because Danville buyers and insurers increasingly ask for a written record. Gas inserts and wood-burning fireplaces both get the same careful treatment. If your chimney has sat idle through a long San Ramon Valley summer, a sweep before that first fall fire catches creosote buildup and any nesting before it becomes a problem. We repair what we find, so you won’t need a second contractor for minor fixes.
Dryer Vent Cleaning in Danville
Dryer vents are a fire hazard, not a minor chore. Dryer Vent Cleaning in Danville clears the lint that builds up faster in larger homes with longer vent runs, which describes a lot of Danville’s executive houses. We use Famco venting products when sections need replacing, and we check the termination point outside the home. A clogged vent makes your dryer run hotter and longer, and in a valley with this much dry fuel around, that’s not a risk worth taking. This is a named, dedicated service for us, not an afterthought.
Chimney Repair in Danville
Chimney repair in Danville is often a documentation job as much as a structural one. Gas fireplaces and inserts in the 1980s-2000s upscale homes along Diablo Road and in Blackhawk were installed and vented years ago, and homeowners ordering pre-sale or insurance inspections need proof the system is sound. The dry summers and idle seasons mean creosote and animal nests accumulate, but the real repair calls come from chase covers leaking into attics, cracked crowns, and liners that have simply aged out. We handle the full scope of Chimney Repair work, from the liner to the cap.
Chimney Cap Installation
Signs you need it
Birds nesting in your flue, water in the firebox, or a cap missing after a windy valley storm all point to needing a new cap.
What it costs in Danville
A new chimney cap in Danville typically runs $350 to $800, depending on the flue size and whether we’re fabricating a custom fit for a tall multi-flue chase.
How we do it
We measure the flue or chase, set the cap with mechanical fasteners, and confirm the spark arrestor mesh meets the standard for your fireplace type.
Chimney Liner Installation
Signs you need it
Cracked flue tiles, a failed camera inspection, or gas exhaust smell back in the living space means the liner has failed and needs replacement.
What it costs in Danville
Full liner installation here usually lands between $2,500 and $6,000, with DuraFlex or Olympia Chimney liner systems specified for the job.
How we do it
We remove the old liner when needed, size the new one to the appliance, and install it with a proper insulated setup where the chimney passes through living space.
Chimney Flashing Repair
Signs you need it
A water stain on the ceiling near the chimney or damp drywall in the attic after rain points to failed flashing at the roofline.
What it costs in Danville
Flashing repair in Danville typically costs $450 to $1,200, depending on roof pitch and access on these taller two-story homes.
How we do it
We pull the old flashing, cut new step and counter flashing to fit, and seal the joint with a roofing-grade sealant that holds up to valley sun.
Chimney Crown Repair
Signs you need it
Cracks across the concrete crown, pieces missing from the top, or water running down the inside of the flue are all signs the crown has failed.
What it costs in Danville
Crown repair here usually runs $500 to $1,500, with resurfacing common on the wide masonry crowns of 1980s-2000s custom homes.
How we do it
We clean the crown, fill cracks with the right mix, and strike a proper slope so water drains away from the flue instead of pooling.
What Chimney Repair Costs in Danville
| Item | Typical range in Danville |
|---|---|
| Chimney cap installation or replacement | $350 – $800 |
| Chimney liner installation | $2,500 – $6,000 |
| Chimney flashing repair | $450 – $1,200 |

Do I really need a new liner?
Only if the old one is cracked, separated, or not rated for your appliance. We don’t recommend liners without camera evidence you can see for yourself, and we’ll tell you honestly when a HeatShield resurfacing will extend the existing liner’s life instead. Call (833) 736-8208 for an exact quote. Estimates are free.
How often should a chimney be swept in Danville?
Once per burning season, which here means before you light the first fire in fall. A heavy-use wood burner may want a mid-season check, but most Danville homes with occasional fires do fine with an annual sweep and camera inspection. Call (833) 736-8208 to book yours.
Brands We Service in Danville
We stock and install professional-grade chimney and venting materials, including Gelco, Olympia Chimney, Famco, and Copperfield. When a Danville job needs a cap, a liner component, or a venting piece, we’re pulling from our brands rather than whatever generic part the supply house had on the shelf, which means tighter fits and less waiting for correct parts.

Often yes, and the answer depends on your specific HOA’s rules. Exterior work like caps, crowns, and chase covers sometimes needs a quick architectural review. We’ll work with you on what the job involves so you can get the approval you need, and we never start exterior work without knowing the property’s requirements.
The honest answer depends on what the camera shows. A cracked liner, a leaking chase cover, or a missing cap will all flag on an inspection. If you know you’re selling, have us do a pre-sale level sweep and camera check first. We repair what we find, so you go into the sale with the documentation the inspector and insurer will ask for.

What Danville Customers Say
"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."
- Ramon Hernandez"Cap keeps the birds out now, which after two springs of scratching noises is worth every penny."
- Nathan Thompson"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
- Yolanda Vargas
