The garage door on a home inspection report

Houses turn over steadily around Putnam County, and the garage door is one of the few systems an inspector can test in the time it takes to walk through the garage. What gets written is a sentence with no price beside it, so the negotiation happens over a number nobody has looked up. Here are those lines in the order a buyer or seller has to act on them, against our published Cookeville repair ranges.

What does a home inspector flag on a garage door?

Almost every garage door write-up comes from a short list of things visible or testable from the garage floor: an opener old enough to have no photo eyes, a door that fails to reverse on contact, extension springs with no containment cable through them, frayed cable at the drums, a door that will not hold itself halfway up, rust through the bottom section or soft wood in the stiles, a missing strut across a wide door, and a door sitting crooked in its opening.

None of that requires taking the door apart, which cuts both ways. The report stays honest about what was seen, and it says nothing about the condition inside the springs. A door can come back clean and still be a year out from the bang.

The flags that come back as “correct prior to closing”

The safety group, which an agent will not let go of and which happens to be the cheapest cluster on the report. An opener with no photo eyes is the oldest flag in the garage. Every opener sold since the early 90s has a pair of sensors down near the floor, so a unit with none predates them, and no accessory turns an old head unit into a new one. That is a replacement conversation at $350-$650 installed, and the one line a seller does better to fix than credit, since a new opener clears the reversal flag below with it.

The reversal test is the one the inspector physically performs. Put something solid under the open door, run it down, watch whether the door stops and comes back up on contact. Some also push up against the closing door by hand to see whether the force setting gives way. A door that keeps pressing has drifted force limits, or a travel setting that believes the floor is lower than it is. Resetting those is work on the motor unit rather than parts, done on a visit already in the garage. When the sensors or the board caused the drift, opener repair runs $95-$250.

Extension springs with no containment cable show up on older track-style doors, which around here means the detached garages behind in-town houses and the places out toward Baxter. The spring stretches along the horizontal track, and when it lets go it becomes a length of steel with somewhere to be. The containment cable runs through the middle of it and holds the pieces. Extension spring pairs run $180-$320 and include safety cables, so a set already at the end of its life clears the flag with it.

Frayed cables and a door that will not hold halfway

Two lines, one set of parts underneath them, and the pair most likely to get more expensive between the inspection and the closing. Cable fraying starts at the drum where the cable winds and reads as broken strands standing off the wrap. Early is the good time to hear it, because a cable that parts under load takes the door down crooked with it. Cable replacement is $150-$250, and both sides go together since the partner cable has the same mileage on it.

The halfway line is a spring reading taken from outside the spring. Released from the opener, a door lifted to waist height should stay where it was put. One that sags back or climbs on its own is out of balance, and the report will use that word. Read it as springs at or near the end of their count. Builder-grade springs are rated 10,000 cycles, roughly 7-10 years of normal use, and a torsion spring pair is $220-$420 installed.

Rust at the bottom, soft wood, and a door that got hit

Steel doors rust at the bottom section first, because that edge sits on a slab that stays wet for days after a plateau rain. An in-town brick ranch on its original door shows it there before anywhere else. A stain on the paint is worth nothing in a negotiation. Rust a fingernail goes through is structural, and that section carries the bottom brackets the cables pull against. One bad section on a door still in production is panel replacement at $250-$800. On a discontinued model, or once the rust has climbed into a second section, it becomes the new door conversation: $1,200-$1,800 for a single, $1,600-$3,000 for a 16x7 double.

Wood doors fail in the stiles, the vertical members at the edges of each section. Soft wood low on a stile is where the hinge screws live, and screws in punky wood are how a section sags out of square. A wood door gone soft in the stiles does not get repaired back into a good door, and an honest quote will say so.

The missing strut on a 16-foot double is the line most buyers skim. A strut is the horizontal brace across the inside of a section, and without it a wide door bows in the middle every time the opener lifts it from a single point. Adding one is hardware and a bracket on any visit that has the door open already. Left long enough, the bow cracks a section and the panel range applies instead.

A door re-hung crooked after somebody backed into it reads worst on paper and is often the smallest number on the page. It came off, went back up, and the track never got straightened, so the gaps run uneven down one side. Track repair and an off-track reset run $125-$300, and only a creased section adds the panel price to that.

How much of the list does a garage door tune-up clear?

A garage door tune-up is a maintenance visit that adjusts, lubricates, and tightens what is already hanging there instead of replacing it. On an inspection list that covers the reversal and force settings, the travel limits, photo-eye alignment, lubrication of hinges and rollers and the spring, the track bolts and hinge screws that have worked loose, and the door’s balance where the springs still have life left. On a typical report that is most of the safety group plus the crooked door, cleared in a single visit.

What it does not clear: a spring at the end of its cycle count, a frayed cable, an opener with no sensors, rust, rotten wood. Those are parts and they carry the ranges above. Twice-a-year maintenance is what keeps the list short to begin with, and it is the difference between a report that says “adjust” and one that says “replace.”

There is no flat tune-up price on this site. A visit starts at the $49-$89 service call and diagnosis, applied toward the repair when you go ahead, and whatever the door needs gets its own line at its published range, the way a written estimate reads here for any job.

Bargaining item, same-visit fix, or a whole-door conversation

The report line	How to treat it
Opener has no photo eyes	Whole-unit swap, better done than credited
Door does not reverse on contact	Same-visit fix unless a part caused it
Extension springs, no containment cable	Same visit, usually with the springs
Cable frayed at the drum	Same-visit fix, do not wait on it
Door will not hold halfway	Bargaining item, priced as a spring pair
Rust through the bottom section	Bargaining item, panel or whole door
Wood stiles soft at the bottom	Whole-door conversation
Missing strut on a wide door	Same visit, hardware only
Crooked after a vehicle strike	Same visit, track work

Most of that column is ordinary garage door repair in Cookeville, priced the same in a closing as on a Tuesday. A buyer asking for a credit against a line with no number attached is guessing, and the guess is rarely low. A seller who hands over that credit instead of a receipt pays it.

Before the response letter goes back, take a flashlight out to the garage. The model and date are stamped on the side of the opener head. The sensors are either at the bottom of both tracks or they are not. Rust either sits on the paint or comes through it, and a thumbnail tells you which. If a line matches nothing you can see from the floor, ask the inspector which version was meant. “Safety reverse inoperative” covers a settings adjustment and a dead opener both, and those sit a long way apart in dollars.
