Monahan Masonry

About

Monahan Masonry is a masonry contractor based in Cedarburg, Wisconsin, serving Ozaukee County and the North Shore areas (including communities of Port Washington, Saukville, Grafton, Cedarburg, Mequon, Thiensville, Bayside, River Hills, Fox Point, Brown Deer, Glendale, Whitefish Bay, and Shorewood). The company focuses on masonry restoration and chimney repair for residential and commercial properties.

Chimney services include targeted repairs, routine maintenance, and full restoration to resolve typical problems from Wisconsin winters, aging components, and everyday use. These include:

• Chimney repair — Restoring deteriorated mortar joints, replacing spalled or damaged bricks, and performing full or partial chimney rebuilds to ensure long-term structural integrity and weather resistance.
  
• Chimney inspections — A detailed evaluation to identify problems such as cracked flue liners, deteriorated mortar joints, or blockages, allowing issues to be caught before they worsen and helping maintain safety and structural integrity.
• Chimney leak repair — Work to locate and correct sources of water entry, which may involve repairing cracked crowns, faulty flashing, or worn mortar to stop interior water damage, staining, or mold growth.
• Flashing repair — Restoration of the seals where the chimney meets the roof, using methods like re-caulking for minor gaps or installing new stepped and counter-flashing when damage is more extensive, to provide effective waterproofing against weather and thermal movement.
• Chimney cap replacement — Removal of a damaged concrete crown and installation of a new one using high-strength concrete mixes, reinforcement, expansion joints, and an overhanging drip edge to protect the chimney structure from rain, snow, and water penetration.
• Liner Installation — Installation of code-compliant stainless steel chimney liner systems to safely contain and vent combustion gases, improve drafting, reduce creosote accumulation, and limit heat transfer to surrounding materials.

These services emphasize structural safety, prevention of water intrusion, and preservation of the chimney's function and appearance in local homes. The company uses established chimney repair techniques and materials suited to the region's climate.

Masonry repair provides thorough fixes, preventive maintenance, and structural restoration to correct widespread issues from freeze-thaw damage, long-term settling, moisture, and natural wear. These include:

• Tuckpointing — Careful removal of deteriorated, cracked, or eroded mortar joints weakened by freeze-thaw cycles, weathering, and moisture, and replacement with fresh, matched mortar to restore the bond between bricks or stones, prevent water intrusion, strengthen the wall, and preserve appearance.
• Brick repair — Targeted removal and replacement of cracked, spalled, loosened, or displaced bricks, impacts, or long-term moisture exposure, using locally sourced matching replacements reset with proper mortar to reinforce the structure, stop progressive damage, and maintain uniform strength and look.
• Lintel replacement — Removal and replacement of rusted or failed steel lintels over windows and doors, where moisture causes rust expansion that cracks masonry and leads to sagging. Temporary shoring is used, and a new steel beam with corrosion-resistant coating is installed to restore load-bearing support, prevent displacement, and ensure long-term stability.
• Stone masonry repair — Restoration of natural stone affected by cracking, joint erosion, or displacement from weathering and settling. This includes repointing joints, or replacing deteriorated stones with matching material to improve weather resistance, maintain structural integrity, and preserve natural texture and appearance.
• Building restoration — Comprehensive commercial masonry repair of aging structures with cracked facades, spalling brick or stone, or shifting elements from settlement and wear. Damaged areas are addressed and reinforced with compatible materials to revive structural soundness, enhance weather protection, and extend the building's life while respecting its original design.
• Historic restoration — Specialized repair of older or historic buildings where age, prior alterations, or incompatible fixes have caused deteriorating mortar or weathered stone. Period-appropriate techniques and matching original materials are used to preserve architectural heritage, avoid mismatches, and protect the property's historical value.
