Local risk factors in El Cajon
Because of these factors, El Cajon homeowners most often need foundation repair, water damage restoration and fire damage restoration.
Embers and smoke reach homes miles from the flames. Fire-rated roofing, ember-resistant vents and good HVAC filtration reduce damage.
Earthquakes crack foundations, chimneys and supply lines. Flexible gas and water connections and foundation bolting reduce risk.
Expansive clay swells when wet and shrinks in drought, which moves slab foundations and cracks walls, floors and plumbing.
Hard water leaves scale in water heaters, faucets, dishwashers and shower valves, shortening their lives. A softener protects new fixtures.
