A Mobile garage is not an indoor room
Garage cabinets fail for one reason on this coast: they were specified as though the garage were part of the house. It is not. A garage has no air conditioning, a door that opens directly to outside air several times a day, and a concrete slab that condenses moisture on its surface during humid spells. That is a completely different environment from the kitchen twenty feet away.
The numbers make the point. NOAA's 1991 to 2020 climate normals for Mobile Regional Airport record a mean dew point of 72.0 degrees on 15 July against 39.4 degrees on 15 January, a 32.6 degree seasonal swing, with annual precipitation of 66.15 inches. Inside the house, air conditioning flattens most of that. In the garage, nothing does. The USDA Forest Products Laboratory's own guidance is explicit that its recommended interior moisture figures assume buildings without unusual moisture sources, and a garage on the Gulf Coast is precisely an unusual moisture source.
What actually survives in a Mobile garage
| Material | Holds up? | Notes |
|---|---|---|
| Powder-coated steel | Excellent | Indifferent to humidity. Dents rather than swells. Heaviest and usually dearest |
| Exterior or marine grade plywood, fully sealed | Excellent | Waterproof adhesive. Wants every cut edge sealed, including the back of the toe kick |
| Cabinet grade plywood, fully sealed and wall hung | Good | The usual practical answer. Failure comes from unsealed edges, not from the panel |
| MDF, fully sealed, wall hung | Fair | Flat and cheap, but any breach in the seal at a cut edge ends it |
| Melamine with unsealed cut edges | Poor | The exposed core wicks moisture at every unbanded edge |
| Bare particleboard | Fails | Swells permanently. Not worth installing in an unconditioned Gulf Coast garage |
Assessment based on the exposure described above: unconditioned air with a 32.6 degree seasonal mean dew point swing (NOAA 1991 to 2020 normals, Mobile Regional Airport) and a slab that condenses in humid spells.
Laying out a garage that has to keep a car in it
Start by subtracting. The garage door track and the opener rail take the ceiling and the wall nearest the door. The water heater, the electrical panel and the hose bib each take a patch of wall that has to stay clear for access. The car doors take a swing radius on each side. What is left after all of that is the wall you can actually use, and in a standard two car garage it is usually the back wall plus one side.
Zone by weight and frequency
Heavy and bulky goes low, ideally in deep base cabinets or on a floor-standing plinth unit. Things in weekly use go between about 36 and 60 inches where you can reach them without moving anything. Seasonal, light and rarely used goes high, above 72 inches, including up into the roof structure if the trusses allow. That ordering is obvious once stated and almost never followed, which is why most garages have the Christmas decorations at knee height and the daily tools on the top shelf.
The bench
A bench at 36 inches with drawer banks underneath and closed storage above is the standard arrangement and it works. Two refinements are worth the money: a sacrificial top layer of hardboard or thin plywood screwed over the structural top, which you replace in an afternoon every few years instead of ruining the bench, and a power strip run along the back of the bench at splashback height rather than relying on one outlet at knee level.
Why wall hung is the default here
Three reasons, only one of which is about moisture. First, a cabinet held off the slab does not wick condensation up through its bottom panel, which is the failure mode described above. Second, you can sweep, blow or hose the floor without working around a toe kick that collects everything. Third, a wall hung run visually gives the floor back, which is most of the psychological benefit people are actually buying.
The requirement is fixing into framing. Garage walls are frequently unfinished, which actually helps: the studs are visible, so there is no guessing. Where the wall is finished, the studs get located properly rather than trusted to drywall anchors, because a loaded garage cabinet carries real weight and a drywall anchor carries almost none of it.
The one place floor standing wins is a heavy bench or a tool chest housing, where the load path straight into the slab is genuinely better. Even there, levelling feet or a plinth that holds the carcass an inch or two clear of the concrete solves the moisture problem without giving up the load capacity.
What garage cabinets cost in Mobile, AL
There is no published dataset that separates garage cabinetry from other cabinetry, so the honest framing is to anchor against general published cabinet figures. HomeAdvisor's 17 June 2026 national installed ranges are $100 to $300 per linear foot for stock, $150 to $650 for semi-custom and $500 to $1,200 for custom. A garage run generally prices below a kitchen of equivalent length because the finish standard is lower, there are fewer doors and drawers, and there is no countertop.
| Run | Linear feet | At $150 per ft | At $650 per ft |
|---|---|---|---|
| One wall of wall-hung uppers | 10 ft | $1,500 | $6,500 |
| Uppers plus a bench and drawer bank | 14 ft | $2,100 | $9,100 |
| Two walls, uppers, bench and tall units | 22 ft | $3,300 | $14,300 |
Our arithmetic against HomeAdvisor's national semi-custom per linear foot range, 17 June 2026, used here as the closest published reference. No dataset publishes garage cabinetry separately, and none publishes anything specific to Mobile, Alabama.
The cost guide carries every published figure with its publisher and date attached.
Before you commission a garage run
- Open the garage door fully and measure the lowest point of the door and the opener rail.
- Mark the water heater, the electrical panel and any hose bib, and keep required access clear.
- Park as you normally would and mark the car door swing on the floor with tape.
- Measure the tallest and heaviest item you need to store before any shelf height is fixed.
- Decide wall hung or floor standing per section, rather than for the whole run.
- Confirm the cabinet material, and specifically that every cut edge is sealed or banded.
- Ask whether the bench top has a replaceable sacrificial layer.
- Plan where power goes, because a new circuit is electrical work and not cabinetry.
Garage cabinets across Mobile County and the Eastern Shore
The specification does not change much across the region, because every garage from Saraland to Gulf Shores sees the same unconditioned coastal air. What does change is the building: older Mobile houses often have a detached garage or a converted carport with limited usable wall, while newer construction in Daphne and Spanish Fort tends to have attached two or three car garages with plenty of wall and a slab that runs level to the door.
Related work: outdoor kitchen cabinets shares the unconditioned-air problem, and laundry and mudroom is often the same project seen from the other side of the door. Full service area, or start at contact.
