Question 1

My house has three fireplaces but we only ever use the one in the great room. Do the others still need sweeping?

Accepted Answer

They need looking at, but not necessarily the same service. That's the normal setup here — a big masonry or oversized prefab firebox in the main room plus a bedroom unit and something on the patio. The great room flue is the one building real creosote and the one that actually needs the brush. The bedroom and patio units, if they've been converted to gas logs or sit unused for years, mostly need an inspection: checking the cap, the damper position, whether animals or debris got in, and whether a gas conversion was done correctly. We'd rather tell you a flue is clean than sweep something that doesn't need it.

Question 2

We're in a Very High Fire Hazard Severity Zone. What does that mean for my chimney?

Accepted Answer

Mainly the spark arrestor. Every flue needs a code-compliant arrestor screen in good condition, and that gets enforced here — it also comes up during insurance inspections and at sale. After Woolsey, a lot of owners in this area found out their caps had corroded mesh, missing screws, or gaps at the crown where embers could get in or out. We check mesh condition, how the cap is fastened, and the seal where it meets the crown on every visit. If the arrestor is failing, we'll say so and show you a photo of it rather than just writing it on a sheet.

Question 3

What usually goes wrong on Calabasas chimneys?

Accepted Answer

Cap and flashing wear, more than anything. These hillside and canyon lots get sustained wind that works at the cap fasteners, lifts flashing edges, and drives rain sideways into the joint between the chase and the roof. On the prefab chases common in homes built from the '70s through the 2000s, we see rusted chase covers that pond water, cracked crown mortar on masonry stacks, and deteriorated flashing seal. The second thing is gas conversions done without addressing the damper — a flue left wide open bleeds conditioned air year round, and a damper clamped shut on a gas log set is a safety problem.

Question 4

Can you come out same day?

Accepted Answer

Sometimes, usually not during the burn season. October through December is when everyone calls at once, and in Calabasas it bunches up further because the AQMD curtailment period runs Nov 1 through Feb 28 — people want their fireplace ready for the nights they're allowed to use it. Outside that window, same-day or next-day is often workable. If you have an active problem like smoke pushing into the room, a visible cap failure after a wind event, or water coming down the flue, tell us that when you call and we'll prioritize it over routine cleanings.

Question 5

What drives the cost on a house like mine?

Accepted Answer

Count of flues is the biggest factor here, since so many Calabasas homes have two or three. A single annual sweep on a regularly burned great room firebox is straightforward. Adding a bedroom unit and a patio fireplace costs more, though the additional flues are usually less than the first one because we're already on site. Roof access matters too — steep hillside rooflines and tall chases take longer to work safely than a single-story roof. And if the chimney hasn't been swept in many years, or a gas conversion left debris and old refractory behind, the first visit runs longer than the ones after it.
