What we do
Five services, one crew
A once-a-year sweep and a seismic-bracing retrofit get the same technician and the same crew, whether the flue sits behind a Fairbrae Eichler’s flat roof or a Murphy Avenue chimney older than the tech boom itself.
01
Chimney Sweep
Yearly creosote removal from the flue, done ahead of the season’s first fire.
02
Chimney Cleaning
The firebox, smoke shelf and ash pit: everywhere a routine flue brush skips.
03
Chimney Inspection
An NFPA-level condition check, including the pre-sale report South Bay buyers and sellers request.
04
Chimney Repair
Crown, mortar, liner and seismic-bracing work, always scoped in writing first.
05
Chimney Cap Installation
The cap and spark arrestor: the least expensive piece that heads off the costliest repair.

The dry-climate reality
What a dry summer does to a chimney crown
The Santa Clara Valley’s Mediterranean climate means a chimney here rarely fails to rain the way one does in a wetter region; it fails to sun. Months of thermal cycling and UV exposure open hairline cracks in a crown, and when the valley’s occasional heavy winter storm finally arrives, every one of those cracks becomes an entry point.
Come fall, the calculus changes again: dry, gusty Diablo winds raise wildfire and ember risk regionally, and a chimney’s spark-arrestor mesh is one small piece of that picture. We check both the crown’s condition and the cap’s mesh on every visit, whether or not either one is why the appointment got made.
A crown cracked by a dry summer fails the same way a crown cracked by frost does, once the rain finds it.
We check the crown, the flashing and the spark arrestor on every visit, whether or not any of them is why the appointment got made.

We recently purchased a 1920s Tudor and sought a Level 2 NFPA 211 examination. The tech didn't simply sweep he crawled into the attic to verify clearances against the roof framework, and documented everything in a crystal clear …

I was concerned about insurance requirements for the chimney. They performed a detailed inspection, provided a professional report with photos and video, cleaned the system, and made the small repairs needed. …

The damper on our masonry fireplace became hard to open and close. During the service they lubricated the linkage, replaced the worn rope seal, adjusted the fit for tighter closure, cleaned the throat area, and polished the glass …

Completed the full chimney cleaning today. Inspection revealed creosote glaze and some lint from the surrounding area. …

Questions
What people ask before calling
Do you publish a street address?
No. We are a service-area business with no public storefront, the same as our Google listing shows. Every job happens at the customer’s property, inside our twenty-mile radius from central Sunnyvale.
What are your hours?
Call and we will confirm today’s hours: someone answers and can tell you directly rather than a schedule printed here going stale.
Are your Google reviews real?
Every one of the 47 lives on our Google Business Profile exactly as posted, nothing trimmed, nothing hidden. The link on this page goes straight to that profile, not a hand-picked list.
Do you work on gas fireplaces as well as wood?
Yes, though the venting and burner components on a gas system need a different check than a wood-burning flue. Tell us which you have when you book.
What is included in a free estimate?
We review what you tell us and either give you a straightforward scope right away, or set up an inspection first when the situation needs a closer look. Neither path obligates you to book.
Do you serve my city if it is not on the list?
If your address falls inside roughly twenty miles of central Sunnyvale, very likely yes. Call and we will confirm before you book anything.
Tell us what changed
Tell us what the fireplace is doing that it did not do last season, and we will tell you plainly what it needs.
