The work

Fireplace Repair in Sunnyvale

We repair cracked firebox panels and masonry, parge rough smoke chambers, fix or replace dampers, and service gas fireplaces, valves and pilot assemblies. Pellet stoves and inserts are serviced too.

If smoke comes into the room, we find out why before we fix anything. The cause is often the damper, the smoke chamber or the flue size, not the firebox.

See the full fireplace repair page for every detail of the work.

Why it matters here

Fireplace Repair in the California climate

Northern California has mild, wet winters and long, dry summers. The ground moves, the sun is strong, and wildfire season brings embers.

Earthquakes crack masonry chimneys at the roof line and loosen the crown. Many towns require a spark arrestor cap, and a cracked flue tile is the most common finding after a quake.
