Chimney sweep and repair in Union City
Two merged towns, Alvarado and Decoto, along the Hayward Fault.
No obligation. Someone answers every day, 7 a.m. to 9 p.m.
The short answer
Union City formed in 1959 from the merger of the older towns of Alvarado and Decoto, and its chimney stock reflects that combined history, some genuinely old construction near each original town center, and postwar-through-1980s tract housing filling in the rest as the merged city grew around the BART corridor. Nation Wide Chimney Sweep & Repair scopes a Union City call the same as any mixed-age neighborhood: an inspection tells us more than the house’s decade alone.
Local specifics
What is true about Union City
- 01
Union City incorporated in 1959 by merging the previously separate towns of Alvarado and Decoto, and both original town centers retain older residential blocks distinct from the tract housing that later filled the space between them.
- 02
The city sits along the Hayward Fault, which runs through the eastern hills of southern Alameda County, making a seismic-bracing check a standard part of any inspection on Union City’s older unreinforced masonry.
- 03
Union City’s growth accelerated after BART service arrived in 1970 near the current Union City station, drawing new residential development that added to the postwar tract stock already filling in around Alvarado and Decoto.
Housing stock
What the housing stock means for the chimney work
Union City’s oldest chimney stock sits in the original Alvarado and Decoto town centers, brick construction old enough to need mortar, crown and seismic-bracing attention. The postwar and BART-era tract housing that fills the rest of the city, built mainly from the 1960s through the 1980s, runs more typical brick-and-metal-flue or factory-built construction with wear proportional to that later era.

Tyler W.
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. Everything was accepted without any issues. Very smooth process.

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 doors. The damper now moves smoothly and keeps heat inside much better on cold nights. It was a small repair but it made a big daily improvement for our family.

Completed the full chimney cleaning today. Inspection revealed creosote glaze and some lint from the surrounding area. They used powerful vacuums and brushes to clean everything installed a new mesh screen cap and parged a small void in the smoke chamber. The entire fireplace area looks refreshed and ready.

Questions
What people ask about Union City
Are Alvarado and Decoto’s chimneys older than the rest of Union City?
Generally, yes: both original town centers carry older residential stock than the postwar and later tract housing that filled in the city after its 1959 merger.
Does the Hayward Fault affect chimney inspections in Union City?
It is a real factor; the fault runs through southern Alameda County’s eastern hills, so we check seismic bracing on older unreinforced masonry as standard practice here.
