Most chimney problems are preventable. Crown failures, water damage, animal nests, creosote buildup, dryer vent fires — every one of them can be caught early with the right maintenance cadence. Here’s the schedule we recommend for San Diego homes.

October — pre-burn inspection and sweep

The single most important date on the chimney calendar. Schedule before you light the first fire of the season.

What to do:

  • CSIA Level 1 inspection ($89) for any chimney you’ll use this season
  • Sweep service if you didn’t sweep at the end of last season ($189 for standard masonry, $269 for stove)
  • Stage 2 creosote removal if camera scan shows it ($200–$400 add-on)
  • Cap inspection from the roof — verify spark arrester mesh is intact, no rust-through, no animal damage
  • Damper test — opens fully, seals when closed, handle works smoothly
  • Smoke alarm and CO detector test on the same floor as the fireplace

Why October: fall is when the busy season starts. Schedule by mid-October to avoid the November–December rush. Sweeps book 3–4 weeks out by Thanksgiving.

November — homeowner pre-burn checklist

Once the inspection is clean, run through the homeowner pre-burn checklist before the first fire:

  • Damper fully open, you can see daylight up the flue
  • Firebrick has no cracks wider than 1/16”
  • CO detector and smoke alarm working
  • Wood is fully seasoned (split and stacked 12+ months)
  • A rolled newspaper torch is ready for flue priming
  • Window opens slightly during first fires to relieve negative pressure if needed

First fire of the season should be small — let the flue and masonry warm up gradually before a full load.

December–February — burn season hygiene

During heavy use months, weekly maintenance:

  • Empty ash pan when it’s 2/3 full (leave a 1-inch ash bed in masonry fireboxes — it reflects heat into the fire)
  • Burn only fully seasoned hardwood (oak, almond, eucalyptus split and stacked 12+ months)
  • Open the damper fully for the first 30 minutes of every fire
  • Don’t smother fires with green logs to make them last — that’s the recipe for Stage 2 creosote
  • Note dry times on the dryer — creeping past 60 minutes = dryer vent needs cleaning

If you see any of these, call mid-season:

  • Smoke spilling into the room
  • Black flakes accumulating on the smoke shelf
  • Visible water in the firebox after rain
  • Animal sounds from the chimney
  • Glass on the wood stove blackening fast

March — shoulder season check

The end of the burn season is the right time for the last sweep of the year (if you’re on annual cadence) and any repair work that doesn’t need to wait.

What to do:

  • Final sweep of the season if you used the fireplace heavily
  • Schedule repair work — crown rebuilds, tuckpointing, flashing repair all benefit from being done in the shoulder season when masons aren’t booked solid
  • Annual stove service — gasket inspection, baffle clean, catalyst check (cat models)
  • Take photos of the chimney exterior for your records — easier to spot changes year over year

Why March: scheduling repair work in spring means it’s done before fall, you avoid the summer heat that makes roof work miserable, and you have time to deal with any surprises the inspection turns up.

April–June — repair season

If your fall inspection or spring sweep flagged anything, this is the time to address it:

Common spring repair work:

  • Crown rebuild or sealing ($400–$2,400) — best done before summer heat
  • Cap replacement ($225+) — quick install, no scheduling pressure
  • Tuckpointing ($350–$1,800) — masons available, weather cooperative
  • Flashing repair ($450–$1,400) — coordinate with roof work if needed
  • Liner installation ($1,200–$4,500) — major work, give it spring scheduling time

What can wait until next year:

  • Cosmetic-only mortar joint repair
  • Crown sealing on hairline cracks (still serviceable)
  • Decorative work

July–August — dryer vent cleaning

While we’re on the maintenance calendar, annual dryer vent cleaning belongs here. Heat season makes it less convenient, but the vent itself is at its driest and easiest to clean.

What to do:

  • Schedule dryer vent cleaning ($149 wall-vented, $249 roof-vented)
  • Inspect the lint screen housing — vacuum out the slot the screen slides into
  • Note dry times for the year — if they’ve crept past 60 minutes, schedule sooner

If you’re scheduling chimney work in spring, ask about adding the dryer vent to the same trip — saves a separate visit fee.

September — pre-season scheduling

The best time to schedule the October inspection. Sweeps are still available without the rush. You get first pick of mornings and weekends.

If you’ve been on the fence about a repair from spring, this is the deadline — anything not booked by mid-September gets pushed past the start of burn season.

Annual cost summary

For a typical San Diego household with a single fireplace on annual cadence:

  • Annual Level 1 inspection: $89
  • Annual sweep: $189 (often credited from inspection)
  • Annual dryer vent cleaning: $149
  • Total annual maintenance: ~$330

Plus repair work as needed (see the chimney repair cost guide for ranges).

If you have a wood stove insert or pellet stove, add $80 to the annual sweep service ($269 instead of $189).

If you skip annual service and let buildup compound, you’re looking at $750+ for Stage 3 creosote removal, $1,200+ for crown rebuild, $2,400+ for stainless reline when problems finally surface — usually all at once.

Maintenance plan vs. à la carte

We don’t currently offer a maintenance plan with discounted bundling. Each visit is priced à la carte, and we book a year out for clients who prefer to lock in the schedule. Most clients book the October slot at the end of their previous October service.

Some sweeps offer annual maintenance contracts at a small discount. The math usually works for heavy users (Backcountry, East County) who’d benefit from priority scheduling. For typical use, à la carte is fine.

Bottom line

The annual chimney maintenance calendar:

  • October: Inspection + sweep before burn season
  • November: Pre-burn homeowner check
  • December–February: Use season hygiene, watch warning signs
  • March: Final sweep, schedule repair work
  • April–June: Repair season — crown, cap, masonry, liner, flashing
  • July–August: Dryer vent cleaning
  • September: Schedule next October’s inspection

Total cost is roughly $330/year for inspection + sweep + dryer vent. Repair work as needed.
