You can safely check your chimney's condition from the ground and inside the firebox without climbing a roof. Look for crumbling mortar, rusted dampers, or white staining on bricks. If you spot major structural shifts or heavy buildup, stop immediately and call Andrew C. Chimney Company.
Gathering Tools and Setting a Safe Boundary
Before you begin, gather a strong flashlight, binoculars, and a screwdriver. Most importantly, establish a 'ground rule' for this safety check: do not climb onto your roof. Seattle's frequent rainfall makes surfaces slippery, and older roofing materials can be fragile. Use binoculars to view the chimney crown and upper flashing from the safety of your yard or driveway. If you cannot see a specific section clearly, that is a sign to bring in a professional rather than risk a fall. We cover various chimney inspection Seattle , but your self-check should be visual only.
Checking Exterior Masonry for Moisture Damage
Seattle’s damp climate is harsh on historic brickwork. Using your binoculars, scan the chimney exterior for 'spalling'—bricks where the face is flaking off or crumbling. Look for moss or vegetation growing in the mortar joints, as this holds moisture against the structure and leads to decay. Check the mortar joints between bricks; if they are receding or missing, you need tuckpointing repairs. Also, look for white, powdery stains called efflorescence, which indicates moisture is moving through the masonry and evaporating.
Inspecting the Firebox and Damper Operation
Move inside and shine your flashlight into the firebox. Look for cracks in the firebricks or missing mortar joints on the interior walls. These can allow heat to transfer to your home's framing. Open and close the damper; it should move smoothly and seal tightly when shut. If it is rusted or difficult to move, do not force it. A stuck damper is a fire hazard and often signals that moisture has been entering the flue. If you notice water stains in the firebox, review our guide on chimney warning signs .
Warning Signs That Mean Stop and Call a Pro
Stop your inspection immediately if you see certain red flags. A chimney that is visibly leaning away from the house indicates a failure in the foundation. If you notice pieces of tile or brick in the firebox, the flue liner may be collapsing. Shiny, black creosote buildup that looks like tar or stalactites means you are overdue for a sweeping. Do not attempt to chip away 'glaze' creosote yourself; it is highly flammable and hard to remove. In these cases, check our pricing and schedule a visit.
Tasks You Should Never DIY
Homeowners should never attempt to sweep their own chimneys or remove creosote using shop vacs or wire brushes. Without the proper cameras and rods, you risk pushing dangerous soot into your living space or missing hidden blockages. Additionally, never attempt waterproofing or masonry repairs from a ladder. Historic Seattle homes require specialized materials that allow the brick to breathe; standard sealants can trap moisture and destroy the chimney. Leave the sweeping and mortar work to the experts at Andrew C. Chimney Company.

Frequently Asked Questions
Does the heavy Seattle rain require more frequent masonry inspections for my chimney?
Yes, Seattle’s persistent rain accelerates mortar decay in older brickwork. You should visually inspect your chimney exterior twice a year for moss growth or crumbling joints. If you see white staining, call Andrew C. Chimney Company for a professional assessment.
Why does my old fireplace smell like damp campfire when it rains in Capitol Hill?
That smell is caused by moisture mixing with creosote deposits in a cold chimney. It is common in humid neighborhoods like Capitol Hill. This indicates your chimney may have a draft issue or leaky cap; consult our troubleshooting guide or call a sweep.
Is it normal for the bricks on my chimney to look flaky or peel?
No, flaking is called 'spalling' and means water is trapped inside the brick, freezing and expanding. It is structurally damaging to Seattle homes. Do not seal it with paint; you need a pro to assess the brick integrity and potentially repair or replace the masonry.
