Fitchburg Garage Doors: Repair or Replace an Old Door

Quick answer: Repair an old door when the door itself is sound and only moving parts have failed, like springs, cables, rollers, or the opener. Replace it when a wood door has rot in more than one section, rust has eaten through a steel door, or the maker no longer builds panels for your model. A new 9-foot single door usually runs $900 to $1,500 installed.

Prices are planning ranges, not quotes. The real number depends on door size, the shape of the opening, and what the tech finds once the door is open.

Fitchburg is a city of about 30,000 people just south of Madison in Dane County. Its garages run from older homes with decades-old doors to newer subdivisions where the steel is barely broken in. If your door is on the older end, you will face this choice sooner or later. For help in person, see our Fitchburg garage door repair page.

The choice is rarely about the one part that just broke. It comes down to the whole door: what it is made of, how much life the panels have left, and whether you can still get parts. Walk through the checks below before you spend money either way.

Start with the door, not the broken part

A snapped spring or a frayed cable feels like the big problem, but those parts are standard. A tech can replace them on nearly any door, old or new. What decides repair versus replace is the condition of the sections, the stacked panels that make up the door.

So before you think about the part that failed, look at the door face inside and out. Sound sections mean a repair is money well spent. Sections that are rotted, rusted through, or badly bent mean you may pay for a repair and still need a new door soon.

Wood doors: how to check for rot

Wood doors can last a long time, but only with paint or stain kept up every few years. Once water gets in, rot follows.

Rot almost always starts low. Snowmelt, rain, and road salt splash against the bottom section all winter, and water sits where the door meets the floor. To check, press a flat screwdriver into the bottom rail and the lower corners of each section. Firm wood pushes back. Soft wood gives, flakes, or crumbles.

A small soft spot in one place can sometimes be cut out and patched. The bigger worry is rot in the rails and stiles, the frame pieces where the hinges and brackets bolt on. If those are soft, the screws have nothing to hold. A door in that shape can pull apart under the load of the springs and opener.

Wood also matters for the springs. A wood door is often heavier than a steel one of the same size. Springs are sized to the weight of the door, so anyone working on a wood door has to match them to it.

Steel doors: where rust starts

Older steel doors fail in a different way. Rust starts at the bottom edge, where salty slush collects, and at any deep scratch that cuts through the paint.

Light surface rust can be sanded, primed, and painted. Rust that has made holes, or steel that flakes away at the bottom, is a bigger problem. Pay close attention to the spots where the bottom brackets and hinges attach. Those points carry real force, and thin, rusted steel there is a safety issue.

Dents are a separate question. A single dented section on a sound steel door can often be replaced on its own, if you can still get one.

Can you still get parts?

This question settles more repair-or-replace choices than any other. The moving hardware is easy. Springs, cables, rollers, and hinges are made to standard sizes and fit most doors.

Sections are different. A replacement section is ordered from the maker of your door, and the wait depends on them. Look for a sticker on the inside of the door, often on an end stile or the top section, that names the maker and model. If the maker has dropped that model, or is no longer in business, a matching section may not exist. Sections have to fit together at the joints, so a close match from a different door rarely works well.

When one section is damaged and no match exists, replacing the whole door is usually the only clean fix.

Insulation and how you use the garage

Most old wood doors and single-layer steel doors hold very little heat. An insulated steel door has a foam core between two steel skins. That core also makes the door stiffer and quieter when it runs.

Whether that matters comes down to how you use the space. If the garage is attached, the door is part of the barrier between the cold and your house. If you work out there in winter, you will feel the difference. A detached garage used only for parking may not need insulation at all. Weigh it against your own use rather than paying for it by habit.

Safety checks on an older door

Some old doors have safety gaps that need fixing whichever way you go.

Many older doors hang on extension springs, the long springs above each track. Check for a steel cable threaded through each one and tied off at both ends, since it holds a broken spring in place. If you find no cable, have one put in with any repair.

Look at the opener too. Openers sold before 1993 may lack photo eyes, the floor sensors that stop the door from closing on a person or pet. An opener without them should be replaced. We install LiftMaster openers, and replacing the door is a good time to update the opener as well.

The cost math

Add up what the door needs now, plus what is likely coming soon. Then compare it to a new door.

A matched pair of torsion springs usually runs $320 to $420.
Rollers, cables and other parts are priced after we see the door.
A new 9-foot single door usually runs $900 to $1,500 installed.
A new 16-foot insulated steel door usually runs $1,400 to $2,400 installed.

Check the wood around the opening too. If the wood jambs the tracks bolt into have rotted, we may need to replace them first.

One way to think about it: if an old door needs repairs that add up to about half the price of a new door, and the sections are showing their age, the new door is often the better spend. If the sections are sound and only a spring broke, repair it and keep the door.

What a replacement looks like

If you go with a new door, we install Haas and C.H.I. steel doors. Both offer insulated models and carriage-style faces that look like wood from the street. The tech measures the opening, the headroom above it, and the side room before quoting, because those numbers decide which door and tracks will fit. The estimate is free. The quote spells out what happens to the old door.

If you choose repair, ask the tech to note anything else that looks worn, like cables or rollers. That gives you a clear picture of what the next few years may cost.

Frequently asked

Can an old wood garage door still be repaired?

Often, yes. If the wood is solid, the moving parts can be swapped on almost any door. That means springs, cables, rollers, hinges, and tracks. Repair stops making sense when rot has reached the rails that hold the hinges, or when more than one section is soft.

How do I check my garage door for rot?

Press a flat screwdriver into the bottom rail and the lower corners of each section. Sound wood resists. Rotted wood feels soft, gives way, or crumbles. Also look for peeling paint, dark stains, and gaps where the panels meet the frame, since those let water in.

Can I replace just one damaged section of my door?

Sometimes. A replacement section is ordered from the maker of your door, and the wait depends on them. If the maker no longer builds your model, a matching section may not exist. In that case a full new door is usually the better choice.

Is an insulated garage door worth it?

It depends on how you use the garage. For an attached garage, or one you work in during winter, an insulated door keeps the space warmer and makes the door stiffer and quieter. For a detached garage used only to park, a non-insulated door may be all you need.
