Garage Door Panel and Section Replacement in San Diego

When one section can be replaced

A sectional door is usually four or five horizontal sections hinged together. Each one can come out and be replaced on its own, so a bumper dent or a cracked panel does not automatically mean a new door.

Section replacement makes sense when:

• The damage is limited to one section, sometimes two.
• The maker still offers your model in your color and panel design. Clopay, Amarr and Wayne Dalton are the common steel doors here.
• The rest of the door is straight, the springs and cables are sound, and the tracks are not bent.

The bottom section takes most of the hits: bumpers, lawn mowers, and the car that rolls forward one foot too far. If that just happened, our guide to a garage door hit by a car covers what to do first.

Matching your door: make, model, color and design

A new section has to match its neighbors in height, thickness, panel pattern, color and the profile of the joints between sections. A close guess leaves a section that does not seal or does not line up.

So we identify the door first. Many doors carry a maker's label on the inside, and when it is gone the panel design, thickness and insulation narrow it down. We measure section height and door width and photograph the joint profile.

Two honest limits. Colors fade, so a new white section can look brighter than a door that has had twenty summers of sun. And when a model is discontinued, no matching section exists. Then the choice is painting the door so a near match blends in, or a new door.

How a section swap goes

1. Identify and measure. Photos first, then a visit to measure and confirm the model.
2. Quote and order. You get a measured quote. Once you approve it, the section is ordered to match.
3. Swap. With the door closed and the spring tension released, we take out the damaged section, move the hinges, rollers and any strut to the new one, or renew worn ones, and set it in place.
4. Rewind and balance. The springs are wound back, the door is balanced, and the opener settings and safety reverse are tested.

Safety: the bottom section carries the bottom brackets, which hold the lift cables under full spring tension. Never unbolt them, and never try to take out a section with the springs wound. This is not a do-it-yourself job.

Cracks, bows and struts

Not every damaged section needs replacing. Some problems are fixed in place.

• Bowed sections. Wide doors can sag in the middle over the years. Struts are steel stiffeners bolted across the inside of a section, and a 16 ft door usually has one or two across the top section. A strut added to a section that has started to bow stops the sag before it cracks.
• Cracks at the opener bracket. The opener pulls on the top section at one point, and thin steel can crack around it. An operator reinforcement bracket and a strut spread that load.
• Torn hinges. Hinges that crack or pull loose are covered on the rollers and hinges page.

Split or rotted panels on wood doors are a different job, covered on the wood and custom doors page.

Section or a new door: how we call it

We would rather fix the door you have. But a section is a special order, and past a certain point the money is better spent on a new door.

• Replace the section when one section is damaged, the model is still made and the rest of the door is sound.
• Look at a new door when two or more sections are damaged, the model is discontinued, the steel is rusting through, or the springs, cables and rollers are all due at the same time.

We are not a licensed contractor. Garage door repairs under $1,000 in labor and materials do not require a California contractor license (Business and Professions Code section 7048), and we stay inside that line. A new garage door is a job for a licensed contractor, and we say so. If a section job would cross that line, we tell you before anything is ordered. Our repair or replace guide lays out the trade-off.

Panel repair across San Diego County

Section replacement works well on the steel sectionals of 1990s and 2000s tract homes, from Eastlake and Otay Ranch to the newer streets of San Marcos. Those are often standard builder models, which improves the odds that a matching section is still made.

Older neighborhoods are a different story. In Clairemont and other 1950s and 1960s tracts, the door may be a replacement from any decade, and older steel models are often discontinued. Some homes still have one-piece tilt-up doors, which have no sections at all.

Many HOA communities, San Elijo Hills among them, set rules on door color and style. Send us yours and we check the match against them before ordering.
