A stairlift from a serious manufacturer, looked after, has a long life in it. The parts that wear are replaceable, and the parts that are expensive generally do not wear.
What does not wear out
The rail. It is steel, it does not move, and on a straight lift it is the single most expensive component. This is why a used curved rail does not make sense, since that rail was built for a different staircase.
What does
Batteries. Consumables rather than failures, typically a couple of years in normal use. The commonest reason a lift stops working, and the cheapest thing to fix.
Drive components. Gears and the drive assembly, over a long time and a great many trips.
Upholstery. Cosmetic, replaceable.
Sensors and switches. Occasionally, and they are tested at each service.
What shortens it, in order
Parking away from a charging point. By a distance the most common. These charge at parking points, so a lift left partway up the stairs is a lift not charging. Bruno and Harmar both design around this.
Ignoring a new noise. Nearly everything we get called out to fix was audible months earlier.
Skipping the annual service. Outdoors this is the difference between a lift that lasts and one that does not, because fixings loosen with thermal movement and grit finds anything that slides.
Adding lubricant. Harmar’s drive uses a nylon polymer gear rack requiring no grease, and adding some attracts grit. Our service page covers what actually needs doing.
What does not shorten it
Use. These are built to run many times a day, and a lift used regularly is usually in better condition than one that sat idle for two years. If somebody has been avoiding using theirs to make it last, tell them to stop.
When to repair and when to replace
Repair while parts are available and the rail is sound, which is most of the time.
Replace when the platform is no longer supported and parts cannot be had, when the person’s needs have changed beyond what the lift is rated for, or when a repair approaches a meaningful fraction of a new unit on an already old machine.
We will tell you honestly which of those you are in, including when the answer is that your existing lift has years left.
Buying with the long term in mind
- Capacity with headroom rather than to the limit, because a lift running near its rating every trip wears faster.
- A manufacturer that will still exist. Parts availability in ten years is a real consideration.
- An installer who services what they sell, since the company that fitted it knows the configuration.
- The paperwork kept. Model, serial, warranty. The serial number is the first thing any service department asks for.
The honest answer on warranties
Manufacturer warranties on structural components are frequently long, sometimes lifetime; on batteries they are short, because batteries are consumables. Read which is which rather than the headline.
And ask who honors it. A warranty from a company that does not service what it sells is a piece of paper. Replacement consumables and general home equipment ship free from our online shop.
Outdoor equipment ages differently
Everything above applies with the timescale shortened. Sealed controls, corrosion protection and drainage are what an outdoor build adds, and annual service is the difference between a lift that lasts and one that does not.
In the Southeast it is heat and humidity rather than cold that does the damage, and pollen and grit working into anything that slides. Using the cover when parked is the cheapest thing that extends its life, and it takes two seconds.
What a well-maintained lift looks like after ten years
Rail sound. Batteries on their fourth or fifth set. Upholstery possibly replaced. Drive components original or replaced once. Running quietly, stopping where it should, sensors working.
That is an ordinary outcome rather than an unusual one, and it is the argument for buying decent equipment and servicing it rather than buying the cheapest thing available.
Selling a house with one in it
A working lift with its paperwork is a straightforward thing to hand over. Keep the model number, serial number and warranty terms somewhere findable, because that is what lets the next owner get it serviced without starting from scratch.
Our service team picks up equipment other companies installed regularly, including where the original installer has gone out of business.
The single habit that matters most
Park it at a charging point. Every time, not most times.
If we could pass on one piece of advice to everybody who owns one of these, it would be that. It costs nothing, takes no effort, and prevents more service calls than everything else on this page combined. Smaller replacement items and general home equipment ship free from our online shop.
