Chimney Sweep & Repair in San Mateo

Peninsula Spanish revivals, stucco chimneys and salt-air corrosion.

Chimney service built around San Mateo homes

The mid-Peninsula is full of 1920s and 1930s Spanish and Mediterranean homes with stucco-clad chimneys. Stucco hides everything — including the cracked brick and rusted steel behind it — which makes camera inspection especially valuable here.

San Mateo Park and Baywood homes typically have decorative stucco chimneys over brick cores. Foster City is built on bay fill with newer prefabricated fireplaces and metal chases that corrode in salt air. Hillsborough estates often have multiple flues in a single stack, and we frequently find flues cross-connected in ways that push smoke into a second room.

Salt-laden air off the bay eats galvanized chase covers, dampers and caps faster than inland cities. We specify stainless steel for anything exposed on the Peninsula because galvanized parts here can fail in under a decade.

What we do most often in San Mateo

  • Stucco chimney crack repair and re-coating
  • Stainless chase cover and cap fabrication
  • Multi-flue separation and smoke testing
  • Full camera scanning of concealed masonry

San Mateo chimney questions, answered

Why does smoke come out of a different fireplace in my house?

That is a cross-connected or improperly separated multi-flue chimney, and it is common in older Hillsborough and San Mateo Park homes. We run a smoke test to prove the path, then separate the flues with dedicated stainless liners.

How do you inspect a stucco chimney without damaging it?

Almost entirely with a camera from inside the flue plus exterior moisture and crack mapping. We only open stucco when the scan shows a structural problem, and then we patch and texture to match.

Why does my chimney cap keep rusting?

Galvanized steel is not appropriate this close to the bay. We replace failed caps and chase covers with 304 stainless, which typically outlasts the roof it sits on.

Do you serve Burlingame, Foster City and San Carlos too?

Yes — our Peninsula crew covers the corridor from Daly City down to Menlo Park, including Burlingame, Millbrae, Foster City, Belmont and San Carlos.
