About
Who comes to the house
Who the business is, what it will and will not claim, and the reviews behind it.
Who we are
Nation Wide Chimney Sweep & Repair sweeps and repairs chimneys out of Sunnyvale, covering the wider Santa Clara Valley. There is no walk-in office: the business operates entirely at the customer’s address, wherever the job is.
Five services make up the work: sweeping, cleaning, inspection, repair and cap installation. Any of the five gets scoped by the same technician, and whichever one a job calls for, the same crew handles it.
What we will confirm, and what we will not
The facts on this page are the ones we can actually stand behind: a 5.0 rating from 47 Google reviews, counted 2026-08-26, and a twenty-mile service radius from central Sunnyvale. Our hours are not yet confirmed for this listing, so call and we will confirm today’s hours directly. We do not publish a licence number, a certification body or a founding year, because none of those is confirmed for this business, and we would rather leave a fact blank than invent one.
The reviews behind it
All 47 reviews on our Google Business Profile are five stars, and every one is visible on the profile itself; we link straight to it rather than a curated excerpt.
“A thorough inspection of the chimney liner found early signs of deterioration that had the potential to grow more severe. By providing timely advice, larger repairs were avoided.” — Anthony Reyes, Google review
“Our prefab metal chimney started making a whistling noise on windy days. These guys climbed up safely and discovered the chase cover had loosened, allowing air to rush through gaps. …” — Jill Bullock, Google review
How a visit actually goes
Nothing touches a firebox before drop cloths are down. A sweep or cleaning runs on a sealed HEPA vacuum from start to finish, and a repair never begins on a verbal, driveway estimate: the scope gets put in writing first, every time.
Where we work
The service area is a twenty-mile radius from central Sunnyvale: the Santa Clara Valley floor from San Jose to Palo Alto, a slice of the mid-Peninsula, southern Alameda County around Fremont, and the Santa Cruz Mountains up to Ben Lomond. If an address falls just outside that circle, call and we will confirm coverage before booking anything.

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 …
