Chimney Repair Seattle: Expert Restoration & Masonry Work

Professional repairs for Seattle's wet climate challenges. Master certified technicians. 45+ years of local expertise.

Why Seattle Chimneys Need Special Attention

Seattle's unique climate accelerates chimney deterioration through constant moisture exposure

37" Annual Rainfall

Every gap and crack in your chimney will leak. Water damage is the #1 chimney problem in Seattle.

Freeze-Thaw Cycles

Winter freezes expand water in cracks, widening them. Spring thaws repeat the cycle—accelerating deterioration.

Aging Homes

Many Seattle homes are 50-100+ years old. Original chimneys show their age and need professional restoration.

Common Chimney Problems in Seattle

Issues we repair most frequently in Seattle homes

Water Leaks Around Flashing

Most common leak source. Seattle's heavy rain finds every gap. Water runs down inside chimney and walls.

Cracked/Deteriorating Mortar

Freeze-thaw cycles crack mortar. Water enters, freezes, expands, and widens cracks—leading to complete joint failure.

Damaged Chimney Crown

Concrete cap cracks from weather. Water runs down inside chimney instead of off the sides—causing internal deterioration.

Spalling Bricks

Water penetrates bricks, freezes, forces pieces to break off. Creates more openings for water—accelerates once started.

Damaged Chimney Liner

Liners crack from heat stress and age. Damaged liner allows hot gases into surrounding walls—fire hazard.

Missing/Damaged Cap

Without a cap, water enters freely. Birds and squirrels nest. Debris blocks the flue. All easily preventable.

Flashing Repair & Replacement

Flashing is where your chimney meets the roof—where most leaks start. We repair or replace using proper techniques:

  • Remove old, deteriorated flashing completely
  • Inspect roof and chimney surfaces for hidden damage
  • Install new flashing with proper overlap and professional sealing
  • Use roofing cement and metal flashing that matches your roof
  • Test the repair to ensure no leaks remain

Typical Cost: $400-800 • Prevents $3,000+ in water damage

Mortar Repointing

Repointing removes deteriorated mortar and replaces it with fresh mortar matched to the original:

  • Remove failed mortar from joints to proper depth
  • Clean joints of debris and old mortar fragments
  • Apply new mortar matched in color, composition, and strength
  • Tool mortar for proper drainage and finished appearance
  • Allow proper curing time and weather protection

Typical Cost: $1,500-3,000 • Restores structural integrity for decades

Chimney Crown Repair & Replacement

The crown is your chimney's primary defense against water entry from above:

Minor Repair:

Small cracks sealed with flexible, weather-resistant sealant that accommodates thermal expansion without re-cracking.

Major Replacement:

Extensive damage requires removal and rebuild with proper slope, overhang, and modern materials that withstand Seattle weather.

Typical Cost: $800-1,500 • Prevents internal chimney deterioration

Additional Repair Services

Firebox Repair

High-temperature refractory materials stop smoke leaks and ensure safe operation.

When Repair is Better Than Replacement

Professional repair often restores function and safety at a fraction of replacement cost

Repair When:

  • Damage is localized to specific areas
  • Structure is fundamentally sound
  • Flashing, crown, or mortar issues only
  • Liner replacement solves safety concerns
  • Costs $400-3,000 vs $5,000+ replacement

Consider Replacement When:

  • Extensive spalling throughout the chimney
  • Major structural issues or severe leaning
  • Foundation settling affecting chimney stability
  • Repair costs approaching replacement costs
  • Chimney unsafe and beyond economical repair

We'll be honest about this after inspection. Most Seattle chimneys benefit from targeted repair rather than full replacement.
