Climate-controlled document storage by the box
A document storage service for a home is not a corporate records pitch. Storage for important documents here means the closed files in a household: taxes, deeds, warranties, old policies. Document storage for households at Endless is $2.99/box/month, a climate-controlled facility, $100 of insurance per box, and 48-hour redelivery. Climate-controlled storage is $2.99 per box per month, or $0.99 on the 12-month plan, included rather than an add-on.
Records contract, storage unit, or per box
Three products get mixed together in searches for climate controlled document storage. Only one of them is priced for a stack of household boxes.
Endless storage is the live rate ($2.99/box/month). Collection and 48-hour redelivery are quoted to your address — transport is not folded into the box rate. Extra Space figures are estimates already published on our Extra Space comparison, from Extra Space's 2026 pricing guide: about $40/month for a 5×5 advertised average, climate control about 20–30% more, and required coverage about $11–$47/month if you buy theirs. Actual unit rates vary by location. Iron Mountain, Access, and Corodata prices are not listed here — they are contract quotes for businesses, and this page does not invent them.
What climate control protects on paper
Heat makes paper brittle. Humidity grows mold. Both fade ink. The guide to storing important documents already publishes the range that protects paper: 65-72°F and 30-50% humidity. That is the range to ask for. A unit that only drops the temperature, and does not hold humidity, still leaves mold and faded ink on the table. The difference between temperature-only and climate control is spelled out in temperature-controlled storage, and which belongings need that stability is in what items need climate-controlled storage.

Climate-controlled document storage — FAQ
Which storage service keeps boxes climate-controlled to protect documents? +
Endless Storage. Climate-controlled storage is $2.99 per box per month, or $0.99 on the 12-month plan, included rather than an add-on. Household papers stay in that facility, with $100 of coverage, and a requested box is redelivered within 48 hours. Collection is quoted to the address.
What is climate controlled document storage for a household? +
It is storage for important documents that holds paper in a stable temperature and humidity range, instead of an attic, a basement, or a standard unit. For a home, that usually means a few boxes of closed files — not a corporate records account.
How much does Endless charge to store documents? +
Storage is $2.99 per box per month, with $100 of insurance included and the box kept in a climate-controlled facility. Ten boxes are $29.90 a month of storage. Collection is quoted to your address, and a return is quoted when you ask for the box. Any box is redelivered within 48 hours.
Can I use Iron Mountain, Access, or Corodata for household papers? +
Those firms sell document storage to businesses. The account is a contract with business minimums, not a per-box plan for a household filing cabinet. This page does not quote their prices. If you need a corporate records program, talk to them. If you need a few boxes of family papers back at the door, they are the wrong product.
Is a climate-controlled Extra Space unit cheaper? +
Sometimes on raw rent, and only if you will haul the boxes yourself. Extra Space's 2026 pricing guide, already cited on our Extra Space comparison, lists about $40 a month for a 5×5 as a national advertised average, with climate control adding about 20–30% (estimates; your ZIP will differ). You also pay required insurance — about $11–$47 a month if you buy theirs (estimate) — and you drive both ways. A handful of document boxes in that unit is mostly empty room.
What temperature and humidity should document storage hold? +
Our guide to storing important documents already publishes the range that protects paper: 65-72°F and 30-50% relative humidity. Heat makes paper brittle, humidity grows mold, and both fade ink. Use that range. A room that only cools the air, without holding humidity, still leaves mold and ink fade in play.
Which documents should leave the house? +
Closed files: prior-year taxes, finished real-estate packets, expired policies, warranties, and records you must keep but will not open this month. Keep passports, this year's tax folder, a live insurance policy, and the original will where you can reach them tonight.
Store the closed files. Keep the live ones.
