FAQ
Are waterproof bins alone enough to protect collectibles during a major flood?
Waterproof bins can help, but they’re usually not a complete solution for a major flood. In real-world flooding, water pressure, submersion time, debris impact, and contaminated water can overwhelm “water-resistant” storage. A stronger approach is layered protection:
- Elevate bins off the floor (shelves/pallets) so shallow flooding never reaches them
- Use gasketed, latching bins and bag or sleeve sensitive items inside
- Keep the highest-value pieces in the safest location (upper floors, interior closets)
- Add leak detection and a plan to move items quickly when severe weather is expected
What materials should never be stored in basements, even with moisture control?
If you have a choice, basements are risky for anything that is highly water-sensitive, hard to replace, or prone to mold/corrosion. Items collectors often avoid storing there long-term include:
- Paper goods (documents, photographs, posters, comics, trading cards)
- Textiles and leather (jerseys, uniforms, vintage clothing, straps)
- Electronics and media (game consoles, vintage audio gear, film, tapes)
- Wood items (antique furniture, framed art with wood backing)
- Metals that tarnish or corrode easily (certain coins, medals, hardware)
If basement storage is unavoidable, keeping items elevated, sealed, monitored, and away from exterior walls/plumbing helps reduce risk—but it doesn’t eliminate it.
How fast do I need to act if a leak reaches my collectibles, and what steps should I take first?
Act as soon as it’s safe—the earlier you respond, the better your odds of limiting staining, warping, corrosion, and mold. Good first steps:
- Stop the source (shut off water if needed) and cut power to wet areas if there’s any electrical risk
- Move items to a dry area and separate wet from dry to prevent transfer and contamination
- Blot—don’t rub paper and photos; avoid peeling stuck pages apart
- Increase airflow (fans/dehumidifier) and remove wet packing materials
- For paper/photos/textiles, if items are saturated or valuable, pause and contact a conservator before attempting aggressive drying
- Photograph everything and keep notes of what was affected (helpful for inventory and any future claims conversations)
