Spring is the best time to inspect and maintain your garage door. After a New England winter — the freeze-thaw cycles, the road salt tracked in, the ice that forms at the bottom seal — your door has been through stress it doesn't get the rest of the year. Thirty minutes of attention now prevents the majority of repair calls that happen in summer and fall.
This checklist covers everything: what to look at, what to do, and what to hand off to a professional. Run through it every May and you'll dramatically extend the life of your springs, cables, opener, and weatherstripping.
Want us to do this for you? Our Summer Ready Inspection ($169 service call) includes a full professional inspection, lubrication, balance test, and safety checks — book anytime.
What You'll Need
- Silicone-based garage door lubricant spray (not WD-40)
- Clean dry cloth or paper towels
- Rubber mallet or small hammer
- Flat-head screwdriver
- A 2x4 or piece of scrap wood (for the balance test)
- Bright flashlight or headlamp
The 10-Point Spring Checklist
Visual Inspection — Springs, Cables, and Hardware
What to look for. Stand inside the garage with the door closed and inspect the torsion spring (horizontal bar above the door). Look for any gaps, cracks, or visible deformation in the coil. Then look at the lift cables running along both sides of the door — they should be taut and free of fraying or kinking.
Check the hardware. Look at the hinges, rollers, and track brackets. Loose bolts are common after a winter of thermal expansion and contraction. Any bolt you can turn by hand is too loose.
If you see a gap in the spring or frayed cable — stop the inspection and call for service before operating the door again. A compromised spring or cable can fail suddenly during operation.
Tighten Loose Hardware
What to tighten. Use a socket wrench or screwdriver to check every bolt and nut on the door hinges, track brackets, and opener mounting hardware. The opener itself is typically mounted to a joist — verify those lag screws are snug.
What not to tighten. Do not touch the bolts on the bottom brackets (the L-brackets at the bottom corners of the door). These are under cable tension and are dangerous to adjust. Leave them alone.
Lubricate Moving Parts
What to lubricate. Apply a silicone-based spray lubricant to: the torsion spring (along the full length of the coil), all hinges, all rollers (the axle shaft — not the nylon wheel itself), and the top of each track where the rollers make contact.
What not to use. WD-40 is a solvent, not a lubricant — it cleans grease off surfaces and leaves metal components dry. It also attracts grit and dirt that accelerates wear. Use only silicone-based or white lithium grease products designed for garage doors.
What not to lubricate. Do not spray the track interior — the rollers ride inside the track and lubricant there causes them to slip and bind. Do not spray the bottom weatherstrip seal.
Test the Door Balance
How to do it. Close the door, then pull the red disconnect cord to disengage the opener. Manually lift the door to about waist height (3–4 feet off the ground) and let go. A properly balanced door will stay in place with minimal drift. If it falls to the floor or shoots up toward the ceiling, the spring tension needs adjustment.
What it means. An out-of-balance door puts enormous strain on your opener motor — it's effectively lifting a heavier load than it was designed for, every single cycle. This is the primary cause of premature opener failure.
Do not adjust the spring yourself. Spring tension adjustment requires winding bars and specific technique. If your door fails the balance test, this is a pro-only fix. Schedule a service call — balance adjustment is usually minor and inexpensive when caught early.
Inspect and Clean the Rollers
What to look for. Rollers take the most wear of any door component. On nylon rollers, look for cracked or chipped nubs around the wheel edge. On steel rollers, look for pitting, rust, or a worn-down profile. Either type should spin freely with no wobble or binding.
How long do they last? Steel rollers last 5–7 years; nylon rollers 10–15 years. But Massachusetts winters accelerate wear — salt, humidity, and temperature swings are harder on rollers than most climates.
If they look worn. Replacement is a minor repair — a full set of 10 rollers typically runs $100–$175 installed. Replacing before they fail entirely prevents the door from jumping the track.
Test the Safety Auto-Reverse
The mechanical test. Place a 2x4 flat on the floor in the center of the door opening. Close the door using the opener. When the door contacts the board, it should immediately reverse direction and fully open. If it doesn't reverse, the closing force limit needs adjustment.
The photo-eye test. Close the door and wave your leg through the photo-eye beam (about 4–6 inches off the floor). The door should reverse immediately. If it doesn't, check sensor alignment (see Step 7).
Why this matters. Federal law has required auto-reverse since 1993, but malfunctioning sensors are responsible for a significant share of garage door injuries. This is the most important safety test on the list. If either test fails, do not use the door until it's fixed.
Clean and Align Safety Sensors
What to do. Wipe both sensor lenses (the small units at each side of the door, near the floor) with a dry cloth. Check that the indicator lights are solid — amber on the sending unit, green on the receiving unit. Blinking lights indicate misalignment.
Realigning sensors. Loosen the wing nut on the sensor bracket, adjust slowly until the green indicator is solid, then retighten. If both sensors look clean and aligned but the auto-reverse test still fails, the sensor wiring may be damaged and a tech visit is needed.
Inspect Weatherstripping and Seals
Bottom seal. The rubber gasket at the bottom of the door takes the most abuse — direct contact with the ground, ice, and UV exposure. Look for cracking, brittleness, or sections that no longer make full contact with the floor. A failing bottom seal lets in water, pests, and cold air.
Side and top weatherstripping. Run your finger along the vinyl strips on both sides and the top of the door frame. If they're brittle, tearing, or pulling away from the frame, they need replacement. This is a DIY-friendly repair — weatherstrip is sold at hardware stores and typically costs $20–$40 for a full set.
Massachusetts winter context. A gap in the bottom seal is also the leading cause of garage doors freezing to the ground overnight. Replacing a worn seal before next winter prevents this.
Check Door Panels for Damage
What to look for. Walk the full width of the door and look for dents, cracks, or sections pulling away from the panel frames. Minor cosmetic dents are usually not structural — but deep creases or sections with visible bending can affect how the door flexes through the track.
Rust and corrosion on steel doors. Spring is a good time to catch surface rust before it penetrates. Small spots of rust on a steel door can be treated with a rust converter, primed, and repainted. Left untreated, surface rust becomes structural rust within 2–3 seasons in coastal South Shore environments.
When to replace panels vs. the whole door. Individual panels can sometimes be replaced, but matching panels for older doors gets difficult after 10+ years. If your door is 15+ years old and showing significant damage, a full replacement often makes more sense than panel-by-panel repair. See 5 signs you need a new door for more on this decision.
Test Opener Features and Backup Battery
Backup battery. If your opener has a battery backup unit, test it now. Unplug the opener from the wall and verify the door still operates. Backup batteries typically last 3–4 years. During a nor'easter when the power goes out, this is what lets you get your car in or out.
MyQ / smart home features. If your opener is connected to a smart home system, test the remote connection and verify notifications are working. These systems use WiFi that occasionally drops the opener device.
Remote and keypad. Test every remote and the exterior keypad. Replace any remote batteries that feel sluggish or require multiple presses. Keypad battery replacement (usually a 9V) is straightforward — consult your opener manual for the replacement interval (typically 1–2 years).
Do not adjust torsion springs or cable tension yourself. Items 1–10 above are all safe for a homeowner to inspect and perform — except for anything involving the spring tension itself. If your balance test fails, or if you see damage to the spring or cables, call a professional. The stored energy in a wound torsion spring makes it dangerous to adjust without proper training and tools.
