We provide professional waterproofing and flashing services designed to protect your chimney from Western North Carolina's challenging weather conditions. Our preventative maintenance solutions stop water penetration before it causes expensive structural damage.
The Danger of Water Damage to Chimneys
Water is the number one enemy of masonry chimneys. When water infiltrates your chimney structure, it can cause:
- Accelerated deterioration of brick and mortar
- Rusting of metal components like dampers and liners
- Deterioration of the firebox assembly
- Rotting of adjacent wood framing
- Staining of interior walls and ceilings
- Mold and mildew growth
- Damaged wallpaper and paint near the chimney
- Cracked flue lining system
- Collapsed hearth support
The freeze/thaw cycles common in Western North Carolina's climate make chimneys particularly vulnerable as water expands and contracts within the masonry structure.
Professional Chimney Waterproofing
The ChimneySaver Advantage
We exclusively use ChimneySaver waterproofing products—the first line of defense specifically designed for masonry chimneys. Unlike generic sealers from home improvement stores, ChimneySaver offers:
- Superior Protection: Reduces water penetration by 99.9% according to ASTM testing standards
- 100% Vapor Permeability: Allows the chimney to "breathe," letting water vapors escape rather than trapping moisture inside
- Siloxane-Based Formula: Creates an invisible barrier that protects without changing the chimney's appearance
- Long-Lasting Performance: Provides 10+ years of protection with proper application
- UV Stability: Resistant to breakdown from sun exposure
Our Waterproofing Process
- Thorough Cleaning: We prepare the masonry surface by removing all dirt, efflorescence, and previous sealers
- Repairs First: We address any existing masonry damage before waterproofing
- Professional Application: We apply the product according to manufacturer specifications for optimal coverage
- Complete Coverage: We treat all exposed masonry surfaces, including the crown, chimney shoulders, and brickwork
- Careful Protection: We shield surrounding areas from overspray during the application process
Expert Flashing Installation and Repair
Flashing is the watertight junction between your chimney and roof that prevents water from entering at this critical vulnerability point. Proper flashing consists of multiple components working together to channel water away from the intersection.
Flashing Services We Provide
- New Flashing Installation: Complete systems for new construction or full replacement
- Flashing Repair: Addressing damaged or improperly installed existing flashing
- Custom Metal Fabrication: Creating flashing components in our metal shop to fit your specific chimney dimensions
- Step Flashing: Installing layered metal pieces that integrate with roof shingles
- Counter Flashing: Cutting and installing the upper components that secure into the chimney masonry
- Cricket/Saddle Installation: Building water-diverting structures for chimneys on the downslope of a roof
Signs of Flashing Failure
- Water stains on ceilings or walls near the chimney
- Rusted or separated metal flashing components
- Missing or damaged caulking at flashing seams
- Loose flashing that has pulled away from the chimney
- Visible gaps between the roof and chimney
- Water in the fireplace after rain
Comprehensive Water Protection
For complete chimney water protection, we recommend a combination of:
- Proper Crown Construction: A correctly built crown with adequate overhang and slope
- Quality Chimney Cap: A well-designed cap that keeps rain from entering the flue
- Professional Waterproofing: ChimneySaver application to all masonry surfaces
- Expert Flashing: Properly installed and sealed flashing systems
- Regular Inspections: Annual checks to catch minor issues before they become major problems
