Reframing it

“Which is cheaper?”is the wrong comparison.

It compares two numbers that are not measuring the same thing, which is how people end up doing the expensive thing twice.

A repair figure and a replacement figure are not comparable, because they buy different quantities of time. A repair buys you the remaining life of everything you did not replace. A new door resets everything and starts a fresh clock on all of it.

The comparison that actually works is cost per year of service. Not a figure we are going to publish — this site publishes none, and the honest reason is that neither number exists until somebody has measured your opening. But the arithmetic is yours to do once you have both quotes, and it is simple: divide each option by the number of years you can reasonably expect it to last, and compare those.

That is where the decision usually resolves, because the two options often look close on the invoice and are nowhere near each other per year.

The input that dominates it is one thing: how old are the other three assemblies? A garage door is four systems on four clocks, and on the overwhelming majority of doors they were all installed on the same day. Replacing a spring on a door whose rollers, track and opener are the same age buys you the interval until the next of them goes — which may not be long. The four-clocks model is set out in full here.

None of that makes replacement the right answer. Very often it does not: a sound door with one failed part and years left in the rest is a repair, plainly. The point is that the calculation is about remaining life across the whole assembly rather than about the fault in front of you.

We will not quote either option before somebody has seen the door, and the reason is on our pricing page rather than repeated here. What we will do is quote both at the same visit, which is the part that makes the comparison possible.

Common situations

Where the answer is usually clearand where it genuinely is not.

Most repair-or-replace questions are not close once the whole assembly is considered. These are the ones we are asked about most.

Only two rows in that table are genuinely close. That is typical: most of these questions resolve quickly once somebody has looked at the whole door rather than the broken part — which is what the diagnosis guide is for.

Beyond the door itself

Three things that move the answerand none of them is the fault.

Once both options are on the table, three considerations change the calculation more than the immediate failure does, and two of them catch people out.

Whether the profile is still manufactured

This decides most damaged-section questions on its own, and age is a poor guide to it — some fifteen-year-old profiles are still current products and some eight-year-old ones are long gone.

If the profile is current, a section swap is straightforward and the result is invisible. If it is discontinued, you are choosing between a visibly mismatched panel on the largest surface at the front of your house and a new door. Establish this before anything else, because it can end the discussion immediately.

Whether the opener comes into scope

This is the one that surprises people at the worst moment. California has required battery backup on residential garage door openers since July 2019, and a replacement door may not be connected to an existing opener that does not have it.

So on the replacement side of your comparison, the opener may not be optional. If yours predates the rule, it belongs in the replacement quote — and a quote that omits it is not comparable to one that includes it. The rule and how to check your own unit has its own guide.

Note the asymmetry: this affects only the replacement option. Repairing an existing door does not trigger it.

Whether you are the one who gets the remaining life

If you are selling within the year, the arithmetic inverts. Cost per remaining year is a poor guide when the remaining years are somebody else’s, and the relevant questions become whether the door is safe, whether it works, and how it looks from the kerb.

In that situation the usual answer is to repair it to sound and safe rather than to replace it — with the honest caveat that on most tract elevations here the garage door is the largest single surface a buyer sees, so a genuinely tired door is doing visible work against the house.

Whether that is worth addressing is a conversation for your agent rather than for us. What we can tell you is whether the door is sound, which is the part that turns up in an inspection report.

None of the three is about the part that failed, which is the point of this page. The fault gets you the visit; these decide the outcome.

The practical offer

We quote bothand tell you which we would do.

Where both options are genuinely viable, you get both in writing from the same visit: what the repair covers and explicitly what it does not, and what a replacement would involve. Plus the answer to the question above — what we would expect to fail next, and roughly when.

We will also say which we would choose and why, and that recommendation is frequently the repair. Six of the nine failures we are called out to most are part-level, so a door that needs one thing doing and has years left in the rest is the common case rather than the exception.

The measure and the assessment are free either way, and free whether you go ahead with either. We cover the whole of Riverside County from one shop in Riverside, and the person who answers the phone is the person who comes and looks at it.
