Chimney Water Leak Repair
Water stains near a chimney can come from the crown, flashing, cap, porous masonry, or adjacent roofing. Locating the actual entry point comes before choosing a repair or compatible masonry water repellent.
Understanding the work
What chimney water leak repair involves
A damp fireplace or a ceiling stain near the chimney can have more than one source. The cap, crown, masonry, flashing, and adjacent roofing all deserve attention before a repair is selected. A stain's location alone does not prove where water entered.
Trace the water-entry point
Rain can enter through an uncovered flue, a cracked crown, failed mortar, or the roof connection. Nearby roof defects and condensation can produce similar symptoms. Describe when the leak appears, wind direction if known, and whether the chimney is being used; these observations help narrow the investigation.
Repair first, then consider protection
Failed flashing needs a roof-connection repair, while damaged joints or crowns need their own masonry treatment. A compatible breathable water repellent may help exposed masonry after necessary repairs. It is not a cure for structural cracks, missing flashing, or an open flue.
Local service
Professional chimney leak repair in Salem, OR
Fan Chimney Service & Masonry specializes in chimney leak repair in Salem, Oregon and the mid-Willamette Valley. If you see water stains on the ceiling or wall near your chimney, damp firebox, musty smell, or rust on the damper, we find where the water is really coming in and stop it.
Chimney leaks are often mistaken for roof leaks. The usual culprits are a cracked or missing crown, no chimney cap, failed flashing at the roofline, a missing cricket behind a wide chimney, or porous brick and mortar soaking up rain. In Oregon, where rain can last for weeks, even a small gap can cause real damage to framing, drywall, and insulation.
We trace the leak before recommending a fix, so you're not paying for a sealer when the problem is flashing. You get photos of the problem and a written estimate for the repair.

When to fix a chimney leak
As soon as you notice it. Water damage spreads behind walls and ceilings, rots framing, and accelerates masonry decay. Take photos of stains after rainfall and note when they appear — it helps pinpoint the source.
What affects the cost of chimney water leak repair
- Source of the leak (crown, cap, flashing, brick)
- Number of entry points
- Roof type and pitch
- Chimney width and whether a cricket is needed
- Interior damage (repaired separately)
- Masonry condition
Every job gets a written estimate before work begins.
Should I just caulk around the chimney?
Caulk and roofing tar are temporary at best and can hide the real problem. Lasting leak repair means proper flashing, a sound crown and cap, and healthy masonry.
