Can I repair my garage door by myself?

Yes, you can. There multiple DIY steps you can take to facilitate your garage door’s reliable operation on a daily basis. Not only will your garage door be happier, routine maintenance saves money because well-maintained, automatic garage doors are less likely to require expensive repairs or replacement parts.

That being said, be careful. Garage doors are heavy, cumbersome and dangerous. Never tackle a DIY garage door repair unless you are 100% confident you can do the job.

Further down the page, we’ve provided a string of videos demonstrating some of the safer, homeowner-friendly, DIY maintenance tasks. If you don’t feel entirely confident, consider that a sign it’s time to contact a licensed garage door repair technician.

Please Note: Many garage door warranties are voided without proof that maintenance and repairs were performed by a licensed professional. If this is the case for your garage door, it’s worth it to let professionals do the work so your parts and/or door replacement are covered should you need to file a warranty claim.

What does a typical garage door maintenance appointment include?

We refer to routine maintenance appointments as “service, lube and adjustment” appointment – and that pretty much sums it up. While there, the technician will:

  • Provide a complete inspection of the entire system
  • Open/close the door repeatedly  – using both manual and remote buttons – testing timing, listening for unusual sounds or watching for tension, hiccups or vibrations that shouldn’t be there
  • Tighten nuts and bolts
  • Lubricate all hinges, rollers, bearings and springs
  • Ensure safety devices are working properly
  • Check and adjust door balance if needed
  • Assess all seals and weather-resistant equipment, replacing as necessary
  • Look for any wear or fraying of cables
  • Lubricate the motor rail
  • Check and reset operator limits

If we feel your door is outdated, unsafe or that repair/replacement costs will become excessive in the near future, we’ll make recommendations about new, automatic door systems for your consideration.

Common Residential Garage Door Problems & Quick Solutions

Here are some of the most common issues we’re frequently called about, as well as DIY solutions.

The remotes aren’t working

The “lock” feature on your wall button was accidentally engaged. Press it and hold it down for three, full seconds and see if that does the trick. If not, you may need to re-program your remote.

My remote operates the neighbor’s garage, or vice versa

Whenever a new garage door is installed, there’s a chance a neighbor’s remotes share the same frequency. This can also happen whenever you replace a remote control or key fob. All you have to do is re-program the remotes, and that should do the trick. Then, walk outside, use them – and keep an eye out up and down the street to make sure you have a unique combination engaged.

My garage door is making a hideous, screeching sound

Yes, it is awful – and it’s a sign the door track requires lubrication and – potentially – an adjustment the door hasn’t been serviced in a while. Use silicone spray to lubricate all of the door’s moving parts. If your door is older, the worn, steel ball bearing rollers might be the culprits, in which case replacing them with nylon-coated rollers is the solution.

The door starts, stops and reverses – while the light flashes and blinks

Oops! Sounds like someone or something knocked the laser safety sensors out of whack. Typically located at the base of each side of the track, these sensors have to be aligned to communicate. Here’s a video showing you how to re-align safety sensors when they’re out of whack.

There’s a gap under the garage door that didn’t used to be there

In some cases, this is simply a concrete issue – has it cracked, settles, bubbled up, or eroded? In other cases, you may need a limit adjustment or a new astragal. If the concrete isn’t the issue, contact us to schedule a service appointment. (925) 671-7606.

Please continue scanning below to watch more videos demonstrating DIY fixes. And, again, when in doubt, contact the residential garage door pros at R&S. We look forward to getting your garage door back on track.


The door starts to go down then reverses and goes back up and the lights start blinking.
