Bricks are like hard sponges. They soak up water. In the winter, that water freezes and expands, popping the face right off the brick. It's called the freeze-thaw cycle, and it shreds chimneys.
We use a professional-grade, breathable water repellent (not a sealer!). Sealers trap moisture inside; repellents let the brick 'breathe' while stopping rain from getting in. We also redo the flashing,that metal skirt at the bottom of the chimney,because that's where 90% of leaks happen.
Common Issues We Fix
These are common problems we review during scope planning. We flag root causes, not just symptoms, and explain what drives cost or risk. If your issue is not listed, we will assess it during inspection.
Water Stains
Damp spots on your ceiling or walls near the fireplace.
White Stains (Efflorescence)
That white powder on your brick means water is moving through it.
Rusted Flashing
Old steel flashing that has rusted through or pulled away from the brick.
Loose Caps
Improper caps letting rain and critters in.
What the inspection covers
We review the visible condition, likely moisture or safety concerns, access, and the work needed to address the problem. The estimate separates recommended work from optional improvements.
Safety and site planning
We review access, prep, containment, and permit or inspection questions during scope review.
- PPE, fall protection, scaffold/ladder safety where the work requires it.
- Permit and inspection needs identified before scheduling.
- HEPA dust control where indoor or occupied areas.
- Project-specific safety and condition checks are confirmed during scope review.
Price planning
Pricing depends on access, materials, damage, and the final project scope.
The written estimate confirms the price after the condition and scope are reviewed.
- Common add-ons: access/scaffolding, premium materials, complex detailing, unforeseen rot/damage.
- Onsite inspection required before any final proposal.
Project checklist
These are common planning items we review so the estimate matches the site conditions.
- Protection: tarps, coverings, safe staging.
- Cleanup and debris handling expectations.
- Photo updates when useful for the project.
