Water Damage Restoration · Foundation Repair · Garage Door Repair
Hard water leaves scale in water heaters, faucets, dishwashers and shower valves, shortening their lives. A softener protects new fixtures.
Bathroom Remodeling · Kitchen Remodeling · Water Damage Restoration
Hail bruises shingles, dents gutters and garage doors and cracks skylights. The damage often leaks months later, so inspect after every big storm.
Severe storms lift shingles, drive rain under flashing and push on garage doors. Wind-rated materials and solid nailing patterns pay off here.
Heavy snow loads and ice dams force water under shingles and into ceilings. Attic insulation and ventilation are the long-term fix.
High humidity feeds mold in bathrooms, attics and crawl spaces and makes air conditioners work harder to dry the air.
Heavy rain and flooding soak floors, drywall and foundations. Standard homeowners policies exclude flood, so check your coverage.
Water Damage Restoration · Mold Remediation · Foundation Repair
A long heating season puts heavy hours on furnaces and heat pumps, and cold snaps stress garage door springs and pipes.
Basements are common here, which adds seepage, sump pump and mold risk below grade.
