The short answer

Storage units price by volume, and unit size is a decent proxy for volume.

  • 5x5: usually a quarter truck, $241.
  • 5x10: 3/8 at $338 or 1/2 at $431.
  • 10x10: 1/2 at $431 up to 3/4 at $587.
  • 10x15: 3/4 at $587 up to a full truck at $732.
  • 10x20: a full truck at $732, often two loads: $732 + $732 = $1,464.

How tightly it was packed matters more than the floor plan. A 10x10 stacked to the ceiling holds far more than a 10x15 with a walkway down the middle.

Why San Antonio fills so many of these

Storage has gone up everywhere along the growth corridors here: out the 1604 ring, up 281 toward Bulverde and Timberwood Park, along Bandera Road, Potranco and out past Alamo Ranch. There are four reasons it fills.

The garage is already full. Houses here have no basement, the attached two-car garage is the storage room, and once that is packed the overflow goes to a unit.

Deployments and PCS. Families attached to Joint Base San Antonio store a household while they are somewhere else, and then the somewhere-else becomes permanent and the unit keeps billing.

Moves that did not finish. A house sold, a downsize happened, and the difference went into a unit as a temporary measure four years ago.

Estates. Somebody's house got cleared into a unit so the family could decide later, and later never came.

The climate-control problem

This is the specifically San Antonio part, and it decides what is inside when you open the door.

A non-climate-controlled unit in this metro is a metal box in direct sun. Interior temperatures through the summer run far above the outdoor air, for months, year after year. What that does over three or four seasons:

  • Upholstery and foam break down. Cushions compact and the fabric powders.
  • Veneer lifts and glue joints let go on solid-wood furniture.
  • Particleboard swells at the fasteners and nothing stays square.
  • Electronics fail. Capacitors do not survive it.
  • Photographs, records and tape warp, stick together or fade.
  • Candles, adhesives and anything wax-based melt and get into everything else.

So the hard conversation is usually not about cost. It is that the thing being stored has already been lost, and the storage bill kept running anyway.

What gets found in there

Mostly the same list. Bedroom furniture, a mattress set, boxes of clothes, holiday decorations, a sofa, a dining set, tools, and between ten and thirty boxes of paper nobody has opened.

ItemFlat price
Sofa / Couch$126
Mattress + Box Spring Set$143
Dresser (Standard)$126
Dining Table (2-4 Seat)$103
Box of Books$45
Bag of Clothes$35
10 Bags of Debris$132
20 Bags of Debris$259
Artificial Christmas Tree$37

Once it is more than a few pieces, the volume ladder is nearly always cheaper. The quote works out both and charges the lower.

Sort before the truck, in the parking lot

The one thing that reliably saves money is deciding what stays before anything is loaded.

Do it in the drive aisle, not inside the unit. A packed unit has no floor space, so sorting in place does not work. Pull everything out, stage it, and put back only what is leaving with you.

Do the paperwork first. Storage units are where the filing boxes ended up, and they hold deeds, titles, tax records, insurance papers and photographs. Once a load has gone, it has gone.

Expect pests. Boxes stored on a concrete slab in this climate for years attract roaches and sometimes rodents, and cardboard on the floor of a non-climate unit goes soft. Bring gloves and open boxes outside.

Facility access, which decides how long it takes

Worth checking before you book, because every facility is different.

  • Gate hours and gate code. Some facilities have access hours narrower than you would expect, and the truck needs the code or an escort.
  • Drive-up versus interior. A drive-up unit with a roll-up door is the fastest job there is. An interior unit means a corridor, a freight elevator, and a cart.
  • Elevator size and availability. Multi-story climate-controlled buildings have one or two, and on the last weekend of the month everybody wants them.
  • Loading bay slots. Some facilities have two bays and a queue.
  • Office notice. Many want to know a truck is coming.

Take a morning slot in summer. A metal drive-up unit at two in the afternoon in July is not a workable environment.

The deadline version

Most storage cleanouts have a date attached, and it is usually the end of the month.

If the unit is behind on payment, facilities in Texas have a process for that which ends in the contents being sold. Deal with the operator directly and early, because once a lien process is under way your options narrow. If you are clearing the unit to stop the billing, the last day of the month is the deadline that matters, and that is the busiest day at every facility in the city.

Book the cleanout for a weekday earlier in the month if you can. Gate queues, elevator waits and bay availability are all better, and the price is the same because there is no same-day or weekend surcharge either way.

The maths worth doing

Run this before you renew again.

Add up what the unit costs you per year. Then look honestly at what is in it, knowing what a few San Antonio summers in a non-climate unit have already done to the furniture and the electronics.

For a lot of people the answer is that one cleanout at $431 for a half truck or $587 for three-quarters ends a bill that has been running for years, and the contents were already gone. Take the photographs, the documents and the two things that actually matter, and stop paying rent on the rest.

Frequently asked questions

How much does a storage unit cleanout cost in San Antonio?

By size: a 5x5 is usually a quarter truck at $241, a 5x10 runs $338 to $431, a 10x10 is $431 to $587, and a 10x15 is $587 up to a full truck at $732. A packed 10x20 is often two full loads, $732 + $732 = $1,464.

Does unit size decide the price?

Only roughly. How tightly it was packed matters more. A 10x10 stacked to the ceiling holds more than a 10x15 with a walkway down the middle, and the price follows the volume rather than the floor plan.

Is anything in a non-climate-controlled unit still usable?

Less than people hope. A metal unit in this metro runs far above the outdoor air all summer, year after year. Upholstery foam breaks down, veneer lifts, particleboard swells, electronics fail and photographs warp. Documents and photos are worth rescuing; the furniture usually is not.

What do I need to arrange with the facility?

Gate code and access hours, whether the unit is drive-up or interior, elevator and loading bay availability if it is a multi-story climate-controlled building, and whether the office wants notice that a truck is coming. Avoid the last weekend of the month if you can.

What should I do before the crew arrives?

Sort in the drive aisle rather than inside the unit, because a packed unit has no floor space. Do the paperwork boxes first, since deeds, titles, tax records and photographs end up in storage units. Bring gloves and open boxes outside, because pests are common.
