New Homeowner Garage Door Checklist: The First 30 Days

A new house comes with a garage door you know nothing about. You don't know how old the opener is, who still has a remote, or when anyone last looked at the springs. The garage door is also one of the main ways into the house, so it is worth a little attention early.

This checklist spreads the work over your first month. None of it takes long, and none of it asks you to touch the parts that are dangerous to adjust.

Day one: lock down access

You have no way of knowing how many remotes the last owners handed out. Neighbors, dog walkers, cleaners and relatives may all have one. Resetting the opener is the single most important thing on this list.

• Clear the opener's memory. Most openers have a learn or program button on the motor unit. Holding it down for several seconds usually erases every paired remote and keypad. Check your opener manual for the exact steps.
• Re-pair your own remotes. Once the memory is cleared, program the remotes you kept, one at a time.
• Change the keypad code. If there is a keypad outside, set a new code. Don't use an obvious one like the house number.
• Reset your car. If your car has built-in garage buttons, program them to the opener. If you bought the car used, clear its old settings first.
• Check for an app. Some openers connect to Wi-Fi and a phone app. Reset the Wi-Fi connection and set it up under your own account so the previous owner no longer has access.

Week one: get to know the door

Find the label on the opener motor. It usually shows the brand, the model number and sometimes the date it was made. Write those down or take a photo. With the model number you can usually find the manual online. It is worth keeping.

Next, find the manual release. It is usually a red cord with a handle hanging from the opener rail. Pulling it disconnects the door from the opener so you can move the door by hand, which is what you do when the power goes out. Only pull it with the door fully closed. If a door with weak or broken springs is open when you pull it, the door can drop fast. We cover the full steps in how to open your garage door during a power outage.

Last, show everyone in the house how the door works, where the wall button is, and why kids should never play with the remote or run under a closing door.

Week two: test the safety features

Openers made for homes today have two safety features you should test right away and then once a month.

• The photo eye sensors. These sit a few inches off the floor on each side of the door. Start closing the door, then wave something like a broom handle through the beam. The door should stop and go back up.
• The auto-reverse. Lay a 2x4 board flat on the floor where the door lands. When the closing door touches it, the door should reverse. If it doesn't, stop using the opener to close the door and have it checked.

If either test fails, stop using the opener to close the door until a professional checks it. If you don't see any sensors at all, the opener is likely old enough that it is missing basic safety features, and it is worth replacing. Our garage door safety guide explains more, and repair or replace your opener can help if it is getting up there in age.

Week three: a careful look over

With the door closed, stand inside the garage and look. Don't touch the springs or cables. You are checking for:

• Springs. Look at the springs above the door or along the tracks. A visible gap in the coil means a spring has broken. Stop using the door.
• Cables. Look at the cables running down each side to the bottom corners. Fraying, rust or slack is a reason to call a professional.
• Rollers and hinges. Look for cracked, wobbly or worn rollers and loose hinge screws.
• The bottom seal. Look for daylight under the closed door, cracks or a seal that has gone hard.
• Sound and movement. Open and close the door and listen. Grinding, popping or jerky movement all mean something. Our guide to common garage door noises explains what each sound usually points to.

Week four: basic care and a professional check

Lubricate the hinges, roller bearings and springs with a lubricant made for garage doors. A light coat is enough. Wipe the tracks clean, but don't grease them. Snug up any loose hinge screws, but leave the bottom brackets alone, since those connect to the cables.

Then book a professional inspection. A home inspection before closing usually looks at the garage door, but it is a general check of the whole house. A garage door visit goes deeper on the parts that carry the weight: springs, cables, balance, the opener's force and travel settings, and the safety features. Here is what a tune-up actually checks. It gives you a baseline, so you know what you are working with instead of guessing.

What to leave alone

Springs, lift cables and bottom brackets are under high tension. They are the parts most likely to cause a serious injury if handled wrong. Don't adjust, loosen or replace any of them yourself. If something looks off, stop using the door and have it looked at. Our list of spring warning signs is a good one to read once.
