Seattle Storage Tip: Damp, Mild Weather and Mildew
Seattle rarely gets extreme heat or cold, but its long, damp months create a different problem: moisture. Months of drizzle and high humidity can lead to mildew on fabrics, mattresses, books and leather, and rust on metal. A climate-controlled unit with humidity control is worth it for anything you care about. Use plastic bins instead of cardboard, leave space between items for air to circulate, and make sure gear like tents, kayaks and bikes is completely dry before you store it.
Where to Look for Storage in Seattle
In-city neighborhoods such as Capitol Hill, Ballard, Fremont, Queen Anne, the U District and SoDo are convenient but tend to have higher prices and fewer large units. For more space for the money, look in Renton, Kent, Everett, Lynnwood, Shoreline and Tacoma. Eastside cities like Bellevue, Redmond and Kirkland are convenient for tech workers but rarely cheap.
Wherever you rent, visit or check photos and reviews for cleanliness, lighting, gated access, video surveillance and access hours. See our checklist of warning signs when choosing a storage unit.
How to Save on Storage in Seattle
- Time it right. Demand peaks in summer, when most moves happen, and around the end of the University of Washington school year in June. Booking in fall or winter usually gets you better availability and pricing.
- Look for move-in specials. Many facilities offer a discounted or free first month. Compare the price after the promotion ends, not just the first month.
- Don’t overbuy space. Pack tightly, stack boxes to the ceiling and use a smaller unit if you can.
- Skip climate control only where it’s safe. Tools, bins and outdoor gear can go in a cheaper drive-up unit.
- Ask about price increases. Some facilities raise rates after a few months. Ask how often rates change before you sign.
