River and lake water that enters a building is contaminated. We extract it, remove porous materials that cannot be saved, clean and disinfect, and dry the structure with air movers and dehumidifiers while logging moisture readings.
In late February 2019 Lake Erie surged to 175.9 m at Port Maitland, and the Grand River Conservation Authority issued a flood warning. Basements, crawl spaces and garages near the water are the places to check after high water or an ice jam.
How We Handle Losses in Dunnville
Dunnville properties near the Grand River, Byng Island and Port Maitland face ice-jam flooding, lake surges, wind, basement flooding and winter pipe bursts. Wet materials left in place can lead to mould if drying is delayed.
Mould usually follows water in Dunnville homes. A basement that took on water and was not dried to verified targets, a slow leak inside a wall, or a crawl space that stays damp through a humid summer can grow mould within days. We contain the area, remove affected materials, HEPA clean, and correct the moisture source. After a fire, we board up, remove firefighting water from the basement, clean soot, and treat smoke odour in ductwork and wall cavities so it does not return. Storm calls in Dunnville usually mean roof tarping, board-up, and drying ceilings and walls after wind-driven rain or ice dams. Every job is documented with photos and daily moisture readings, which your adjuster can review and which show when the structure is actually dry.
