Magnesium Chloride Spreading

What This Service Involves

Magnesium chloride has become a favorite across Puget Sound properties that border landscaping, rain gardens, or pet-heavy walkways because it is gentler than sodium or calcium chloride while still melting ice in the mid-20s and below. The material attracts moisture and stays workable in the damp, humid conditions that define a Western Washington freeze. Our crews apply it in granular or pre-wetted form on sidewalks, entrances, and HOA common areas where runoff sensitivity is a genuine concern. Its lower corrosivity also helps protect the exposed rebar and decorative concrete common in newer developments.

Benefits

Less corrosive to concrete, rebar, and metal railings than rock salt; Gentler on adjacent lawns, shrubs, and rain-garden plantings; Works well in the humid, damp air of a Puget Sound freeze; Easier on pet paws in condo and apartment walkways

Our Process

1) Survey the site for landscaping and pet-traffic areas that need a milder deicer; 2) Remove standing snow so the product reaches the ice surface; 3) Apply magnesium chloride in granular or pre-wetted form at label rates; 4) Inspect treated zones and reapply lightly if freezing drizzle returns

What Affects the Cost

Material cost, which sits between rock salt and calcium chloride; Whether granular or pre-wetted liquid form is chosen; Extent of landscaping-adjacent pavement needing gentle treatment; Reapplication frequency during lingering freezing drizzle; Site accessibility for spreader equipment

Best Time of Year

Magnesium chloride sees steady use from December through February on properties where landscaping and pet safety are priorities.
