The Morning After Closing
You're standing in the garage of your new place, coffee in hand, and you hit the button for the first time as the actual owner. The door groans halfway up, hesitates, then jerks the rest of the way. Or maybe it closes a little crooked, leaving a gap at one corner. The inspector checked a box that said the door "operates," but operating and operating correctly are two different things. Garage doors are one of the most-skipped areas in a general home inspection, because most inspectors run the opener once and move on. Here's what to actually check yourself, especially heading into a Lenawee County winter where ice, salt, and deep cold will find every weak spot.
The Walk-Through Checklist
1. The Balance Test
Pull the release cord to disconnect the opener, then lift the door by hand to waist height and let go. A properly balanced door stays put. If it drops like a stone or flies upward, the torsion or extension springs are worn or mismatched to the door's weight. This is one of the most commonly missed items because it requires manually operating the door, which most inspectors skip in favor of just pressing the remote.
2. Cable and Spring Condition
Look at the cables running alongside the tracks down to the bottom brackets. Fraying strands, rust, or visible kinks mean the cables are near failure. Check the springs above the door for gaps between coils or flat spots on one side — signs of uneven wear that often means one spring is newer than the other, a red flag that a previous repair was done cheaply.
3. Bottom Seal and Weatherstripping
Crouch down and look at the rubber seal along the bottom of the door. In this part of Michigan, road salt spray and slush get flung up from car tires all winter, and a cracked or flattened seal lets that salty water pool under the door instead of shedding it. A failed bottom seal in January means ice buildup right where the door meets the floor, which can freeze the door shut overnight.
4. Track Alignment and Rust
Sight down each track from the bottom. Gaps between the rollers and the track, visible bends, or rust flaking off onto the floor all point toward tracks that have been knocked out of alignment, often from someone backing into the door at some point. Surface rust on tracks is common after a hard winter of salt exposure, but pitting or rust that's eaten into the metal means the track itself may need replacing, not just cleaning.
5. Roller Material and Wear
Cheap plastic rollers get brittle and crack in sustained cold, which is exactly the stress this region puts on a door from December through March. Nylon rollers hold up better. If you see cracked, chipped, or visibly worn rollers, budget for replacement before winter rather than after a roller fails and the door comes off track.
6. Auto-Reverse Safety Function
Place a 2x4 flat on the ground where the door closes and trigger it. The door should reverse immediately on contact. Also wave something in front of the photo-eye sensors near the floor while the door is closing — it should stop and reverse. A door that doesn't reverse on either test is a genuine safety hazard, not a minor fix, and it's one of the most overlooked items in a standard walkthrough.
7. Insulation Value of the Door Panel
Knock on the door panel. A hollow sound usually means a single, uninsulated steel skin. If the garage is attached to the house, an uninsulated door lets a lot of cold radiate into that shared wall during deep-freeze stretches, and it won't hold up as well against the temperature swings between a cold garage and a warm thaw.
8. Apron and Floor Drainage
Step outside and look at the concrete apron right in front of the door. Cracks or a slope that directs water back toward the garage instead of away from it will cause problems during spring thaw, when snowmelt and mud push moisture right up against that bottom seal. This isn't something most inspectors flag because it's technically outside the garage door system, but it directly affects how long your new seal and bottom panel will last.
When to Call Clinton Garage Door
If your walk-through turns up an unbalanced door, worn springs, or cables that look questionable, don't keep running the opener and hoping it holds — a failed spring under tension can cause real damage or injury. Clinton Garage Door can come out, test the balance properly, and handle Spring Replacement with correctly matched springs rather than a mismatched patch job. If everything's functional but showing its age, our Preventive Maintenance service covers lubrication, hardware tightening, and a full inspection of tracks, rollers, and seals before winter puts real stress on all of it.
