If you've lived in Lake Mary for even one summer, you know what the heat and humidity feel like the moment you step into your garage. That thick, sticky air doesn't just make it uncomfortable to grab your bikes or tools. it's quietly working against every metal component in your garage door system, especially the springs.
Lake Mary sits in Seminole County where summers are long, hot, and relentlessly wet. Temperatures push into the low 90s while humidity regularly tops 80 percent. That combination is hard on steel. Garage door springs. whether torsion springs mounted above the door or extension springs running along the tracks. are made from large-gauge steel coil, and steel oxidizes fast in a warm, humid Florida garage. The result is rust, and rust leads to premature spring failure.
Most garage door springs are rated for around 10,000 cycles under normal conditions. In a typical household that opens and closes the door a few times a day, that translates to roughly 7,10 years of service life. But in Central Florida, that timeline can be cut short significantly.
Moisture in the air penetrates the coil surface and begins a chain reaction of oxidation that weakens the steel from the inside out. Once rust forms, the effective strength of the spring is reduced even before you can see visible damage. You might hear a squeaking or grinding sound as the door operates. that's often the first warning sign. A reddish-brown discoloration on the coils is a visual cue that rust is already taking hold.
Neighborhoods like Hanover Woods and Heathrow, where many homes were built in the 1980s and early 1990s with mature tree canopy overhead, see this problem frequently. Shade from oak trees keeps garages cooler but also traps moisture, especially during and after the afternoon thunderstorms that roll through from June through September.
Torsion springs mount horizontally above the garage door opening. They're under significant tension at all times and do the heavy lifting when your opener activates. Extension springs run along the horizontal tracks on each side of the door and stretch to store mechanical energy.
Both types are vulnerable to rust in Lake Mary's climate, but torsion springs tend to be more commonly used on the heavier doors found in the larger single-family homes throughout the area. If you're in one of the custom homes off Rinehart Road or in the Woodbridge Lakes community, you almost certainly have torsion springs. Regardless of type, when a spring fails, the door typically won't open. or worse, it closes suddenly and unsafely.
Never attempt to adjust or replace springs yourself. They're under extreme mechanical tension and can cause serious injury if released improperly. This is a job for trained technicians every time.

The single best thing you can do between professional tune-ups is keep your springs properly lubricated. Here's what works in Florida's climate:
- Use white lithium grease or a silicone-based spray. not WD-40. WD-40 is a degreaser and will strip the lubricant barrier your springs need. Apply a proper garage door lubricant to the full length of the coil every three to four months, or more often if you notice any squeaking. - Inspect for surface rust visually every few months. Light surface rust can sometimes be addressed early; deep corrosion that has eaten into the coil means the spring needs immediate replacement. - Lubricate rollers, hinges, and cables at the same time. These components face the same humidity-driven wear and contribute to how hard the opener motor has to work.
If the rust has progressed to actual corrosion. where the coil surface looks pitted or eaten away. stop using the door and call a professional before the spring snaps. Our FAQ page covers common questions about spring lifespan and what replacement typically involves.
Here's a straightforward piece of advice most homeowners aren't told: if one spring breaks, replace both. Torsion springs are typically installed as a pair, and if one has failed from wear and humidity exposure, the other is likely at a similar stage of fatigue. Replacing just the broken one means you'll likely be calling for service again within weeks or months.
This is particularly relevant for homeowners in established Lake Mary subdivisions where the original springs have been in place since the home was built. A home from 1995 in a community near Lake Mary Boulevard that still has its original springs is on borrowed time.
Homesowners across the Seminole County area. from Lake Mary out to Longwood and Winter Springs. deal with the same climate-driven spring wear. It's not a sign of a defective door; it's just the reality of maintaining mechanical hardware in subtropical Florida. The difference is whether you stay ahead of it or wait for the door to stop working on a Monday morning when you're already late.

How often should I lubricate garage door springs in Lake Mary? Given the high humidity throughout the year, every three months is a practical target. If you hear squeaking or notice the door moving less smoothly, don't wait for the scheduled interval. apply lubricant right away. Always use white lithium grease or a silicone-based product, never WD-40.
How do I know if my spring is broken versus just worn? A broken torsion spring typically produces a loud bang (often described as a gunshot sound) and leaves the door unable to open more than a few inches. A worn spring may cause the door to feel unusually heavy when lifted manually, or the opener motor may strain and slow down during operation. Either situation warrants a professional inspection.
Is it safe to use my garage door if I think a spring is damaged? No. Operating a door with a compromised spring puts excessive strain on the opener motor, cables, and tracks, and creates a genuine safety risk if the spring snaps under load. Disconnect the opener and call for service before using the door again.
