Chimney Sweeping in Lake Arrowhead, CA

Chimney Sweeping for Lake Arrowhead Homeowners

Lake Arrowhead presents a different set of chimney problems to the rest of the mountain, mostly because of the size of the houses. Alongside the original 1920s Arrowhead Woods cabins there is a large stock of substantial lakefront and ridge homes, and those routinely carry three or four flues on a single structure — an open great-room fireplace, a master bedroom fireplace, a wood stove in a lower level, and a furnace or water heater flue sharing the same chase. Owners typically know about the one they light. The furnace flue and the guest-room fireplace nobody has used since 2009 are the ones that turn up blocked, unlined or full of nesting material. The other local factor is occupancy: many of these homes are second residences or vacation rentals, so problems go unnoticed for months at a time and small faults — a displaced cap, a hairline crown crack, a jackdaw's nest — get a full season to become expensive before anyone is there to see them.

Multi-flue chimneys are the norm rather than the exception here, which makes a multi-flue cap and a properly cast crown a much better investment than they are on a single-stack cabin — one cap protects the whole crown surface. Arrowhead Woods carries architectural review through the property owners' association, so anything that changes the visible exterior, including a new cap profile or a rebuilt stack, is worth checking against those rules before we start. Second-home and rental occupancy also shifts the maintenance schedule: we recommend scheduling inspection at the start of the season rather than when the owner happens to be up, because an unoccupied house does not report its own problems.

Creosote is what is left when wood gas leaves the fire unburned and condenses on a cooler flue wall. It starts as a light soot you can brush off, dries into a flaky crust, and — if the flue runs cold, the wood is wet, or the fires are damped down overnight — hardens into a glazed tar that behaves like a fuel lining the inside of the chimney. Glazed creosote ignites around 450°F, and a flue fire burns well past 2,000°F, which is far more than clay tile liners are built to survive. Most tile cracks from a chimney fire, and most homeowners never knew they had one. Sweeping removes the fuel before it can do that, and the inspection that comes with it is what tells you whether last season already did damage.
