A garage door in Washington County works harder than most. Long hot summers, strong afternoon sun, wind, and fine red dust all wear on springs, rollers, seals, and sensors. Most of the checks below take a few minutes and need nothing more than a rag, a 2x4, and a can of garage door lube. The safety tests come from the monthly routine published by DASMA, the door and opener makers' trade group. For why doors wear the way they do here, see our desert heat and dust guide.
Safety first: Everything on this list is look, clean, lube, or test. Never loosen, adjust, or remove springs, cables, or the bottom brackets. If a check fails, stop and call 435-773-8856.
1. Look over the springs, cables, and hardware
How often: Monthly, with the door closed.
What to look for: A gap in a torsion spring above the door, stretched or uneven extension springs along the tracks, frayed or rusty lift cables at the bottom corners, and loose hinges or brackets. Door makers' trade group DASMA lists this visual check as step one of its monthly routine.
If something is off: Look only. Do not touch, adjust, or loosen anything on the springs, cables, or bottom brackets. They hold the weight of the door under tension. See warning signs before a spring snaps and cable repair.
2. Test the door balance by hand
How often: Every month or two.
How: Close the door, pull the opener's red release cord, and lift the door by hand to about waist height. A balanced door lifts smoothly and stays put about 3 to 4 feet off the floor. That is the balance test DASMA describes.
If it fails: If the door drops, shoots up, or feels heavy, the springs are worn or out of adjustment. Reconnect the opener, but do not keep running a heavy door, since it wears out the opener fast. See spring repair.
3. Run the 2x4 reverse test
How often: Monthly, and after any repair or adjustment.
How: With the door open, lay a 2x4 flat on the floor under the middle of the door and close it with the remote. The door should touch the board and go back up. DASMA and the UL 325 opener standard both call for this exact test.
If it fails: If the door presses down on the board and stops, or does not reverse, stop using the opener until it is adjusted. Turning up the force setting to make a stiff door close is a safety problem, not a fix.
4. Clean and test the safety sensors
How often: Monthly, and after a windstorm.
How: Wipe both lenses with a soft dry cloth. Check that both lights are steady. Then start closing the door and wave something through the beam. The door should stop and go back up. The beams should sit no higher than 6 inches off the floor.
Why it matters here: Red dust on the lenses and low sun hitting a west-facing door are two of the most common reasons a door here will not close. See keypads, remotes and sensors and garage door won't close.

5. Wipe the tracks clean, but do not grease them
How often: Monthly, more often after wind.
How: Wipe the inside of both tracks with a dry rag and pull out any sand, leaves, or old grease. Look for dents, bends, or loose track brackets.
Why no grease: Grease in the tracks grabs dust and turns into a paste the rollers have to push through. If a track is bent or pulling away from the wall, call before it throws a roller. See off-track door repair.
6. Lubricate the moving parts, not the tracks
How often: A few times a year. Check your door's manual for its schedule.
What gets it: Hinge pivots, roller bearings (steel rollers), the torsion spring coils, and the bearing plates at the ends of the spring shaft. Use a garage door lube or a light silicone or lithium spray and wipe off the extra.
What does not: The tracks, nylon roller wheels, and the opener belt. A light spray on the spring coils is fine. Adjusting the springs is not. More on this in noisy door, rollers and hinges.
7. Check the rollers and hinges for wear
How often: Every few months.
What to look for: Wobbly or cracked rollers, flat spots, rollers that do not spin, or hinges with cracks or loose bolts. Grinding, popping, or squealing as the door moves is the usual early sign.
If something is off: Worn rollers make the opener work harder. The bottom rollers sit in brackets connected to the cables, so leave those to a technician.
8. Check the bottom seal before summer and after monsoon storms
How often: Spring, and again after the late summer storms.
How: Close the door and look for daylight under it or along the sides. Check the rubber for cracks, flat spots, or stiffness.
Why it matters here: The bottom seal sits on hot concrete in direct sun and gets sand ground into it every cycle. A cracked seal lets in dust, blowing rain, bugs, and scorpions. See weather seals and insulated doors.

9. Check the opener, remotes, and keypad
How often: Monthly when you do the reverse test.
What to look for: An opener that hums, strains, or quits on hot afternoons. A loose chain or a frayed belt. A remote with a short range or a faded keypad. Swap the remote and keypad batteries once a year. Heat runs them down faster.
If something is off: A tired opener is often a sign of a heavy door, so do the balance check first. See signs your opener is dying and opener repair.
10. Know when to stop and call a pro
Stop using the door if: You heard a loud bang, a cable is loose or frayed, the door hangs crooked, it came off the track, or it failed the reverse test.
Leave these to a technician: Springs, cables, bottom brackets, drums, and track rehanging. These are under real tension and cause serious injuries. See repairs you should not DIY, or if it cannot wait, emergency garage door repair.
Quick schedule
- Every month: Look over springs and cables, run the 2x4 reverse test, wipe and test the sensors, wipe the tracks.
- Every few months: Balance test, lubricate hinges, roller bearings, and springs, check rollers and hinges.
- Before summer: Check the bottom and side seals, swap remote and keypad batteries, listen to the opener on a hot afternoon.
- After monsoon storms or big wind: Clear sand and debris from the tracks and the floor under the door, wipe the sensors, recheck the seal.
- Once a year: A professional tune up, or more often if the door runs a lot.
Maintenance notes by area
- St. George: From Bloomington and Green Valley to Little Valley, SunRiver, and Desert Color, west-facing doors take the most sun. Seals and keypads wear first, and late sun can confuse the sensors.
- Washington: In newer neighborhoods like Washington Fields, Coral Canyon, and Sienna Hills, construction dust packs into photo eyes and tracks. Wipe them more often while building is going on nearby. See Washington City garage door repair.
- Hurricane: Near Sand Hollow, Dixie Springs, and Copper Rock, wind-blown sand scores cables and packs sensors. Rentals and garages with boats or side-by-sides cycle the door a lot, so springs and rollers need checking more often. See Hurricane garage door repair.
- Ivins: In Kayenta and on the Snow Canyon side, red dust on the sensor lenses and in the tracks is the usual culprit. See Ivins garage door repair.
- Santa Clara: Wind off the river corridor and hillsides pushes grit into photo eyes and the bottom seal. See Santa Clara garage door repair.
Leeds, Toquerville, and La Verkin are covered by request. See all service areas.

FAQ
How often should a garage door be serviced in St. George?
Do the quick checks on this list once a month. Once a year is a good rhythm for a professional tune up, or more often if the garage is your main entry or the door runs a lot, like a rental near Sand Hollow.
What does a garage door tune up include?
A tune up usually covers a spring and cable inspection, balance check, lubrication of hinges, rollers, and springs, a look at the tracks and hardware, an opener force and limit check, and the safety reverse and sensor tests. We quote it on the call.
Should I grease my garage door tracks?
No. Wipe the tracks clean with a dry rag. Grease in the tracks catches dust and sand and makes the rollers drag. Lubricate the hinges, roller bearings, and springs instead.
What is the best lubricant for a garage door?
A garage door lube or a light silicone or lithium spray. Skip heavy grease and plain WD-40, which is more of a cleaner. Check your door and opener manuals first.
Can I adjust my own garage door springs?
No. Springs and cables hold the weight of the door under tension and are the most dangerous parts to work on. Look, do not touch, and call if a spring or cable looks wrong.
How much does garage door maintenance cost?
We do not post prices. The cost depends on what the door needs, so call or text 435-773-8856 for a free estimate, and see our service fees page for how calls are quoted.
