How often should I have my garage door serviced?

We recommend having your garage door professionally serviced at least once a year, ideally before the cooler months when the door may work harder. Regular maintenance includes lubrication of all moving parts, spring tension adjustment, safety sensor testing, track alignment check, and hardware tightening. Annual maintenance helps prevent unexpected breakdowns, extends the life of your door, and ensures safe operation. Homeowners can also perform monthly visual inspections and lubrication between professional services.

Our technicians respond quickly to emergency calls, typically arriving within 1-2 hours during normal business hours. For after-hours emergencies, we prioritize calls involving security issues or safety hazards. Call us at 619-566-2904 for emergency assistance.

What are the signs that I need a new garage door?

Consider replacing your garage door if you notice: excessive noise during operation, frequent breakdowns requiring multiple repairs, visible damage like dents, cracks, or warping, poor energy efficiency causing drafts, or if the door is over 15-20 years old. A new door can improve curb appeal, increase home value, and provide better insulation and security. We offer free consultations to help you decide between repair and replacement.

How long does garage door installation take?

A standard garage door installation typically takes 3-5 hours, depending on the complexity.

San Marino sits in the San Gabriel Valley with a classic Southern California Mediterranean climate. mild, wet winters and short, hot, arid summers where temperatures regularly push into the upper 80s and low 90s. From June through September, the sun is relentless, humidity drops off sharply, and garage doors on south- or west-facing homes bake in direct sunlight for hours every day.

Most homeowners don't think about their garage door until something stops working. But the truth is, that kind of sustained heat and UV exposure creates a slow, predictable set of problems. and catching them early is a lot cheaper than dealing with them after a full breakdown.

Here's what's actually happening to your door during San Marino summers, and what you can do about it.

What the Heat Is Doing Right Now

Panel Warping and Finish Fading

Wood panels are especially vulnerable in hot, dry weather. Extended sun exposure can cause them to warp, crack, or check along the grain. particularly if the finish hasn't been refreshed in a few years. But wood isn't the only material at risk: even steel and aluminum doors can become extremely hot to the touch in direct sun, which causes paint and finishes to fade faster, especially on south-facing doors. Once a finish starts breaking down, moisture infiltration and rust become the next problem.

If your door's paint is peeling, bubbling, or noticeably faded on one side, that's more than cosmetic. it's the door's protective layer failing.

Weather Stripping Drying Out

Weather stripping is one of the most overlooked components on a garage door, and it's one of the first things to go in a hot, dry climate. Prolonged heat exposure causes rubber and vinyl seals to become brittle, crack, or pull away from the door's edges and bottom. Once that seal is gone, dust, debris, and hot air enter your garage freely. and in San Marino, where summer afternoons can hit 90°F, that means your garage (and anything stored in it) is getting significantly hotter than it needs to.

Check your bottom seal and side trim at least once a year. If it's cracked or missing sections, replace it before the next summer season.

Springs and Hardware Wearing Faster

Heat accelerates the breakdown of lubrication in all of your door's moving parts. springs, rollers, hinges, and cables. When lubrication thins out or evaporates, metal-on-metal friction increases, and parts wear out faster than their rated lifespan suggests they should. Torsion springs in particular are under constant tension, and a combination of heat stress and inadequate lubrication is a common reason they fail earlier than expected.

Broken springs are one of the most common garage door problems and require immediate professional attention. it's not a safe DIY fix. Our post on signs your garage door needs professional repair covers this and other warning signs in more detail.

Opener Motor Overheating

Your garage door opener feels the heat too. Higher temperatures can cause the motor to run hotter than designed, which shortens its operational life over time. The lubrication inside the drive mechanism also breaks down faster in heat, making the system work harder on every cycle. If your opener has been making more noise than usual or is slower to respond during summer afternoons, heat stress on the motor is worth investigating.

Practical Steps to Protect Your Door This Season

Lubricate moving parts before summer. Use a silicone-based or lithium-grease spray on springs, rollers, hinges, and the track. Avoid WD-40. it's a solvent, not a lubricant, and it can actually strip existing grease. Do this in spring before the heat sets in, and again in fall. This is one of the most impactful things you can do yourself, and our garage door maintenance tips post walks through the full routine.

Inspect and refresh your door's finish. For wood doors especially, a UV-resistant sealant or paint coat every couple of years makes a real difference in preventing warping and cracking. For steel doors, a UV-resistant paint or reflective coating helps reduce surface temperature and slows fading.

Check the weather stripping. Run your hand along the bottom seal and side trim. If it's stiff, cracked, or pulling away from the frame, replace it. It's inexpensive material and straightforward to swap out.

Consider insulation if you don't have it. Insulated garage doors aren't just a winter upgrade. they reduce heat transfer into your garage significantly during summer, which keeps your space cooler, protects stored items, and takes some of the strain off your opener. If your current door is uninsulated, it's worth factoring into your next replacement decision.

Schedule a summer tune-up. A professional inspection before peak heat can catch issues. worn springs, fraying cables, misaligned sensors. before they become mid-August emergencies. Garage Door San Marino serves homeowners throughout San Marino and into surrounding areas like South Pasadena, and our team is familiar with how the local climate affects these systems.

Frequently Asked Questions

Q: How often should I lubricate my garage door in a hot climate like San Marino? A: Twice a year is a good baseline. once in spring before summer heat sets in, and once in fall. If your door is used heavily (multiple cycles per day), or if you notice squeaking or sluggish movement, lubricate sooner. Stick to silicone-based sprays or white lithium grease on moving metal parts.

Q: My garage gets extremely hot in summer. Will an insulated door actually help? A: Yes, meaningfully so. An insulated door with a decent R-value (R-12 or higher is worth targeting for San Marino's climate) acts as a thermal barrier, reducing how much heat radiates into your garage from the door surface. It won't turn your garage into an air-conditioned space, but it can drop interior temps noticeably and reduce strain on your opener motor.

Q: How do I know if my garage door spring is about to fail? A: Common warning signs include the door feeling unusually heavy when you disengage the opener and lift manually, the door not staying up on its own, visible gaps or separation in the spring coil, or a loud bang from the garage (which is often a spring snapping). If you notice any of these, stop using the door and call a professional. a broken spring under tension is a serious safety hazard.
