Short answer
RV and oversized garage doors in Houston are usually 12 to 14 feet tall, heavier than standard doors, and need springs, tracks and openers rated for the weight. The key decisions are the opening size, the headroom inside the building, and whether to use a wall-mount or heavy-duty trolley opener.
What makes an oversized door different
A door for an RV, boat or shop is not just a bigger garage door. Its sections are heavier, it needs stronger springs and often two of them, its track may run high up the wall, and its opener has to lift far more weight without straining. Wind load matters more too, because a tall, wide door is a big surface.
We size every part to the door rather than scaling up residential hardware, and we measure the building's headroom and side room first, because those decide the track and opener before anything else.
What an oversized door install includes
- Measuring the vehicle and the opening
- Checking headroom and side room
- Confirming framing strength
- Sections and hardware sized for the door
- Springs rated for weight and cycles
- Track type chosen for the building
- Opener rated for the door, with backup
- Balance and auto-reverse testing
What drives the cost of an oversized door
Oversized doors are priced by size and construction more than anything else.
- 1
Height and width. Bigger doors need heavier sections and springs.
- 2
Insulation. Insulated sections cost more and run quieter.
- 3
Track type. High-lift and vertical-lift track add cost.
- 4
Opener. Wall-mount and heavy-duty openers cost more.
- 5
Framing. Reinforcing a steel building opening adds labor.
RV and boat doors
Motorhomes, fifth-wheel trailers and boats on trailers need openings typically 12 to 14 feet tall, and often wider than a standard double door. Insulated steel sections keep the bay cooler for stored vehicles. We measure the tallest point of the vehicle, including roof air units and antennas, before sizing the door, because an opening that is a few inches short is a costly mistake. Windows high on the door add light without reducing security. We also plan the approach and the slab apron, since a long vehicle needs room to swing in straight.
Tall shop and barn doors
Workshops, barns and steel buildings use tall sectional doors for equipment, tractors and work trucks. These doors see heavy use and the occasional bump, so we use sturdier sections, heavier hinges and rollers, and springs rated for more cycles. On steel buildings, the framing around the opening has to be strong enough to carry the track and springs, and we check it before installing. Where tractors and trucks back in often, we add bottom-section guards and post protectors so a bumped track does not take the whole door out of service.
Openers for heavy doors
Oversized doors need openers rated for their weight and height. Wall-mount openers suit tall doors with high-lift track, because they turn the shaft directly and leave the ceiling clear. Heavy-duty trolley openers suit standard-lift doors with ceiling space. On doors this size, battery backup matters even more than at home, because lifting a tall door by hand in an outage is hard work even when it is balanced. We also fit the opener's safety sensors and set the force and travel limits for the door's weight, then test the reverse.
How an oversized door project runs
Measure
Vehicle height, opening, headroom and side room.
Specify
Sections, springs, track and opener sized to the door.
Order
Door made to size; lead time confirmed.
Install
Framing checked, door, track, springs and opener fitted.
Balance and test
Door balanced by hand, opener and reverse tested.
Tall doors on the northwest side
Tomball, a city of 12,341 at the 2020 census, sits up SH 249 from our service office, and the areas around it are where we see the most detached shops, barns and tall garage bays. Owners there store RVs, boats and equipment, which means doors well above standard height and openers sized for them. We size every oversized door from measurements, not from a standard door scaled up.
How long the project takes
Oversized doors are usually made to order, so the maker's lead time is the longest part. Installation typically takes one to two days, longer if framing has to be reinforced or an outlet added for the opener.
Brands we service and install
Oversized and RV doors are available from Clopay, Amarr, C.H.I. Overhead Doors, Raynor and Wayne Dalton, and we size the springs and opener to each one.
