Magnesium Chloride Application

What This Service Involves

Magnesium chloride stays effective well below the point where ordinary salt stalls, making it a smart choice for the colder outflow nights that occasionally hit Western Washington. It draws moisture from the air to keep working longer, so a single treatment can hold through an extended freeze. We favor it near landscaped grounds, newer concrete, and properties with pet traffic because it is less corrosive and less harsh underfoot. Applied as flakes or brine, it clings to the surface and resists being blown off exposed lots. This makes it a versatile tool for both pretreatment and active melting.

Benefits

Melts ice at colder temperatures than rock salt; Gentler on concrete, landscaping, and pet paws; Attracts moisture to keep working through long freezes; Available as flake or brine for flexible coverage

Our Process

1) Confirm the forecast low favors magnesium chloride; 2) Choose flake or brine based on surface and timing; 3) Apply evenly across target walkways and lots; 4) Monitor the surface and top up during extended cold

What Affects the Cost

Coverage area and product form selected; Severity of the cold event; Proximity to landscaping and pet-traffic zones; Frequency of reapplication needed; Delivery method as granular or liquid

Best Time of Year

Magnesium chloride application is favored during the colder December and January outflow events when Puget Sound lows drop toward the teens.
