How to regularly maintain your garage?

The biggest moving object in your house, your garage door is utilized frequently throughout the day, at all hours, and in all weather conditions. Take the time to perform routine preventative care and maintenance on your garage door if you want to ensure that it runs properly for many years to come. Here are some suggestions for all homeowners:

Look and Listen

  • Seeing your garage door operate every time you use it is the most crucial preventive measure you can take. Is it jerky at times or is it flowing smoothly? Does it produce noises when it operates, such as grinding or scraping? Do the springs, pulleys, and cables on either side of the system appear to be symmetrical?

Tighten up the Hardware

  • In a typical year, a garage door opens and closes over a thousand times. That much movement and vibration have the potential to dislodge the hardware. With a socket wrench, check and tighten each roller bracket’s bolt.

Test the Garage Door Balance

  • The garage door opener will work harder and last less time if your garage door is not properly balanced.
  • Manually raise the door about halfway up after disconnecting the opener by pushing the release handle (often a red wire). The counterweight system (springs) is out of balance if it moves despite being counterbalanced. It’s best to leave the garage door spring adjustment to the experts.

Inspect and Replace the Rollers

  • Whether made of steel or nylon, the rollers need to be checked twice a year and replaced approximately every seven years, or even more frequently if your garage door is used frequently.
  • Rollers that are worn, chipped, or broken need to be replaced right away. Any roller brackets that are not directly connected to the cable system must be taken out and put back in place to do this.

Replace the Weatherstripping

  • To keep the elements out of your home, replace your door’s bottom rubber weather seal strip as soon as it becomes brittle or broken. In hardware and home improvement stores, weather stripping is offered by the foot. With the wide angle of the flange within the door, just cut to size and fit into the grooves.

Lubricate the Moving Parts

  • Maintaining the oil on your garage door parts will provide your system with years of trouble-free operation, and it only takes 10 minutes a year! Apply white lithium grease to the chain or screw of the opener, and coat the overhead springs with a spray lubricant that can be purchased from your garage door professional.

Check the Cables

  • The high-tension cables that raise your door should never be tampered with since they have enough force to murder and maim people. Nonetheless, you can inspect them to determine when to call in a professional. Examine the area close to the bottom roller bracket for damage and broken strands.

Test the Auto-Reverse Safety Features

  • Mechanical and photocell mechanisms are both present. Place a piece of wood or a block on the ground in the door’s path to test the mechanical feature. The door should turn around and go back up again if it strikes the thing as it is coming down. Close your door and simply put your leg through the opening to test the second system, a photoelectric one with beams on either side. You should invert the door.
  • It’s time to get a new garage door opener if your opener is older than 20 years since it might not have these fundamental safety features.

Clear the Tracks

  • Verify that the tracks on either side of the door are clear of obstructions, and if you feel inclined, verify the plumb with a level. A qualified garage door technician must do any significant track changes.

Groom Your Garage Door

  • Don’t forget to look at the actual door. Checking for warping and water damage in addition to chipped and peeling paint is necessary for wooden doors. There may be rust stains on steel doors that require sanding, priming, and painting. Regularly wash your garage door with a gentle all-purpose cleaner while you wash your automobile.

Keep in mind that your garage door makes up around one-third of the outside of your home. If you don’t have the time to perform this type of check-up, get in touch with a garage door expert to arrange a tune-up service call. He will cure everything… flawlessly!
