Roller Shutter Door Maintenance: The Schedule That Prevents Breakdowns

Tohier — Sun, 16 Aug 2026 09:32:49 +0000

Roller shutter doors fail slowly and then all at once. The curtain that jumps its guide on a Monday morning was stiff for a month first; the barrel bearing that seizes was squealing from June. Almost every emergency callout we attend was preventable, and usually for a fraction of what the breakdown cost.

This is the schedule we work to on our own service contracts, adapted for South African conditions — which are harder on a door than the manufacturer’s manual assumes.

Why the local conditions matter

Three things wear doors out faster here than in the climates these products were designed for.

Highveld dust and summer storms. Fine grit gets into the guides and acts as a grinding paste. Then a thunderstorm washes the remaining grease out.
Coastal salt. Within a few kilometres of the sea, galvanised steel corrodes at the fixings and cut edges. This is why we specify heavier galvanising or aluminium on coastal work.
Load-shedding cycles. Operators that switch to battery and back several times a day age faster, and a door driven on a flat battery stops halfway more often than anyone expects.

Monthly: two minutes, no tools

Whoever opens up in the morning can do this.

Listen. Run the door through one full cycle and pay attention. New grinding, squealing or knocking is the door telling you something a month before it stops.
Watch it land. The bottom rail should meet the floor evenly across its width. A curtain that touches down on one side first is running out of square, and that is what eventually pulls it out of the guides.
Sweep the threshold. Grit at the bottom of the guides gets dragged up the full height of the door every cycle.
Test the safety stop. On a motorised door, put a block of wood under the closing curtain. It should stop and reverse. If it does not, take the door out of service until it is fixed.

Quarterly: fifteen minutes with a torch

Clean the guides properly

Wipe the full length of both guide channels with a cloth, then re-lubricate with a silicone or dry PTFE lubricant. Do not use a general water-dispersant spray. It feels right for a week and then leaves the channel drier than before, because it has stripped what grease was left. Dry PTFE is the correct product because it does not attract dust — which is the entire problem in a Gauteng winter.

Check the fixings

Go along the guide brackets and the barrel brackets with a spanner. Vibration works fasteners loose over hundreds of cycles, and a guide that has drifted 3mm out of parallel is the reason a curtain starts jumping. On coastal sites also look for rust bleeding out from under bracket washers — that is corrosion working from the inside.

Look at the slats

Bent slats near the bottom are usually forklift or reversing damage. A single bent slat can often be replaced without stripping the curtain, and it is worth doing early: a bent slat rides badly in the guide and drags the ones above it out of line.

Motorised doors: exercise the backup

Run the door on battery once a quarter. Batteries fail flat, not gradually, and a backup that has quietly died is worth nothing on the day you need it. Also test the manual override release so that everybody on site knows where it is and how it works.

Annually: the proper service

This is the visit worth paying for, whether we do it or someone else does. It should cover:

Barrel and bearings. Bearing wear is the fault that turns a repair into a replacement if it is left. It announces itself as a rumble or squeal from the barrel housing.
Spring tension. The counterbalance inside the barrel loses tension over years. A correctly balanced curtain should hold roughly halfway with the motor released. An unbalanced door puts every bit of that extra load through the operator.
Curtain alignment and end locks. Slats should sit square with their end locks intact. Missing end locks let slats creep sideways in the guides.
Bottom rail and weather seal. The bottom rail stands in whatever water sits on the threshold, so this is where corrosion begins. Seals perish in UV and are cheap to replace.
Operator, limits and safety systems. Travel limits drift; safety edges and photo-eyes need testing, not assuming.
Fire-rated doors: a compliance inspection including the drop test and the release mechanism. This is a legal requirement, not a nicety, and insurers ask for the certificate.

How often, by how hard the door works

Domestic garage, a few cycles a day: annual service.
Shopfront, open and closed once a day: annual, twice yearly at the coast.
Warehouse or loading bay, dozens of cycles a day: every six months, quarterly if forklifts pass through.
Cold store or dusty production line: quarterly. These environments are brutal on seals and guides.
Fire-rated doors: per the certificate, typically annually, and it must be documented.

The five faults that cause most breakdowns

Dry or dirty guides. Cheapest to prevent, most common cause of a jumped curtain.
Worn barrel bearings. Audible for months before failure.
Lost spring tension. Kills operators by making them do the springs’ work.
Corroded bottom rail. Standing water plus a perished seal.
Impact damage nobody reported. Someone clipped it with a pallet jack and said nothing.

Four of those five are found by a torch and a spanner. The fifth is found by asking the staff.

What a breakdown actually costs

The repair invoice is rarely the expensive part. A warehouse door stuck open overnight is a security problem; a shopfront shutter stuck closed on a Saturday morning is a day of trading. Weighed against that, a service visit is cheap insurance — which is why most of our commercial clients run a service contract with scheduled visits rather than waiting for the phone call.

Keep a record

Keep a simple log per door: date, what was done, what was replaced, what was flagged for next time. It tells you when a door has moved from maintenance to replacement territory instead of you finding out through a third repair in a year. For fire-rated doors the log is not optional — you will be asked for it.

If yours is overdue

We service and repair roller shutter doors on any make, including doors we did not manufacture, across all nine provinces from our works in Tarlton, Krugersdorp and branches in Cape Town and George. If you are not sure when yours was last looked at, that is usually the answer in itself.

Send us the door count and your town and we will come back with a schedule and a price. If something has already stopped working, we run 24-hour emergency callouts.

Garage Door Not Closing? 9 Faults, and Which Ones You Can Fix Yourself

Tohier — Sun, 16 Aug 2026 09:31:59 +0000

A garage door that will not close is one of the few household faults that is genuinely urgent — you cannot leave the house open and you cannot always leave the car out. The good news is that most of the causes are cheap, and about half of them you can diagnose from the driveway in under five minutes. Here is how we work through it on a callout, in the order we check.

Before anything else: is it the door or the motor?

Pull the manual release cord and try to move the door by hand. This one test splits the problem in two.

The door moves smoothly by hand. The mechanism is fine. You have a motor, power or safety-sensor problem — faults 1 to 4 below.
The door is heavy, sticks, or will not budge. The motor is not your problem. You have a spring, cable, roller or track fault — faults 5 to 9.

A balanced door should hold its position roughly halfway up when released. If it slams down or shoots up, the counterbalance is out. Stop there and call someone: a door under wrong spring tension is the one part of this list that genuinely hurts people.

1. The safety sensors are misaligned or blocked

This is the single most common cause, and the easiest to fix. Two photo-eye sensors sit near the floor on either side of the opening. If the beam between them is broken, the operator refuses to close — it will usually open again immediately and flash a code on the motor head.

Check: a bin, a bicycle wheel, a coiled hosepipe, a broom, even a spider web or a heavy build-up of dust on the lens. Then check the little indicator LEDs: one steady light on each sensor means aligned; a flickering or dark light means they are out of line. Loosen the bracket, nudge until both are steady, tighten.

Also worth knowing: low winter sun shining directly into a sensor can wash out the beam for twenty minutes a day. If the fault only happens at the same time each afternoon, that is why.

2. The close-limit setting has drifted

The operator learns how far to travel. If it thinks the floor is lower than it is, the door touches down, senses resistance, and reverses — because it assumes it has hit a child or a car. You will see the door go all the way down then come straight back up.

There is a limit adjustment on the motor head, usually two screws or two buttons marked up and down. Small adjustments only. If you overshoot the other way, the door will press into the slab and strain the opener.

3. The remote or wall button has failed

If the wall button works and the remote does not, it is the remote: replace the battery first, then re-pair it. If neither works but the motor has power, the receiver or the logic board is the suspect. If the door closes only while you hold the wall button down, the operator is in a fault mode that deliberately requires constant pressure — that is the unit telling you a safety circuit is unhappy, so go back to fault 1.

4. No power, or a tripped unit

Obvious, and still worth ruling out. Check the plug, the socket and the DB board. After a surge — and we get plenty — an operator can trip internally and need a full power cycle: switch it off at the wall for a minute, then back on. If the unit runs on battery backup after load-shedding and never switched back to mains, it will eventually go flat and stop mid-cycle.

5. A broken spring

Torsion springs sit above the opening; extension springs run alongside the tracks. They are what makes a 90kg door feel like 10kg. When one breaks you often hear a bang like a gunshot from the garage, and afterwards the door is enormously heavy and may close crooked or not at all.

Do not attempt this yourself. A wound torsion spring stores a great deal of energy and the winding bars have to be handled correctly. This is the repair we most often attend after somebody has tried it. Springs are also fitted in matched pairs; replacing only the broken one leaves you replacing the other within months.

6. A frayed or off-drum cable

Lift cables run from the bottom bracket to the drum at each end of the torsion shaft. If one frays or jumps its drum, one side of the door lags, the door goes out of square in the tracks and jams. You will see the door hanging visibly lower on one side.

Look at the bottom brackets and the cables with a torch. Any fuzzy or kinked strand means the cable is on its way out. Cables are inexpensive; the damage a snapped one does on the way is not.

7. Worn rollers, or something in the track

Rollers wear out, especially the nylon ones. A worn roller binds in the track and the door judders, squeals or stops. Run a torch along both tracks looking for a dent, a loose bracket, a screw head that has worked proud, or a build-up of hardened grease and grit.

A track dent is often the result of a reversing bumper. It can sometimes be tapped straight; if the track is kinked, replace that section rather than fighting it.

8. The tracks have come out of alignment

Vertical tracks should be plumb and parallel, at an even distance from the door edge along their full length. Bolts that have vibrated loose over years let a track drift outward, and the door then binds at one particular height every time. Loosening the bracket bolts, tapping the track true and re-tightening solves it — but if you are unsure, leave it, because a track pushed the wrong way will drop the door.

9. Cold, dirt and a dry bottom seal

The unglamorous one. Grit packed into the bottom seal or under the track, or a rubber seal that has perished and stiffened, will stop a door seating properly and trigger the reverse. Sweep the track channel, wash the seal, and lubricate the rollers, hinges and springs with a proper garage door lubricant — not a general water-dispersant spray, which strips the grease and leaves the parts drier than it found them.

What you can safely do yourself

Clean and realign the photo-eye sensors.
Replace remote batteries and re-pair the remote.
Clear the tracks and the bottom seal, and lubricate moving parts.
Power-cycle the operator.
Make small limit adjustments, one turn at a time.

What to leave alone

Anything involving torsion or extension springs.
Lift cables and bottom brackets, which are under spring tension even when the door is down.
Realigning tracks on a door you cannot hold safely.
Opening the motor head beyond the limit adjusters.

When to call

Call if the door is heavy by hand, if you can hear a spring has gone, if a cable looks frayed, or if the door is closing crooked. Those four are not “watch it for a week” faults — a door that is out of balance puts load on every other component, so a R900 spring left alone becomes a bent track and a burnt-out operator.

We run 24-hour emergency callouts and repair garage doors of any make, including doors we did not fit. Most faults on this list are resolved in a single visit with parts off the van. If you would rather get ahead of it, a yearly service catches all nine of these before they strand you.

Not sure which fault you have? Send us a photo of the door and the motor head and we will tell you what we think it is before anyone gets in a van.

Roller Shutter Doors vs Garage Doors: Which One Should You Fit?

Tohier — Sun, 16 Aug 2026 09:30:31 +0000

It is the first question on almost every quote request we get: should this opening take a roller shutter door or a garage door? The two words are often used interchangeably in South Africa, which does not help. They are different products, built differently, and the right answer is usually decided by the building rather than by preference.

The difference in one paragraph

A roller shutter door is a curtain of interlocking horizontal slats that curls around a barrel above the opening. A garage door is a broader category covering several mechanisms — sectional panels that stack under the ceiling, a single tip-up panel, side-hinged leaves, sliding leaves, and yes, roll-up curtains too. So a roll-up garage door is a roller shutter fitted to a house. The useful comparison is not shutter versus garage door, but which mechanism suits this opening.

Start with headroom, not looks

Measure from the top of the opening to the ceiling, or to the nearest beam, pipe or light fitting — whichever is lower. That single number eliminates most of the options before you have thought about anything else.

Under 300mm. A roll-up door or side-hinged leaves. Nothing else fits.
300mm to 450mm. A sectional door becomes possible, often with a low-headroom track kit.
Over 450mm. Everything is on the table.

People routinely order a sectional door on looks, then discover the roof truss sits 250mm above the lintel. Measure first.

What each does best

Roller shutters win on space and security

Because the curtain coils rather than travelling backwards, a roller shutter frees the entire ceiling void. In a warehouse with racking to the roof, a workshop with an overhead crane, or a garage with a flat concrete slab, that is not a nicety — it is the only thing that works. Shutters also take the heaviest specification: industrial curtains span openings a sectional door cannot, and security shutters with anti-lift brackets are genuinely hard to force.

Sectional garage doors win on sealing and noise

Slats have to move against each other to curl, so a shutter cannot seal like a panel door. If the garage is attached to the house, has been converted into a room, or sits under a bedroom, an insulated sectional door is a different experience: full perimeter seals on all four edges, a foam core that damps the boom, and a garage that stays close to house temperature.

Appearance goes to the panel doors

On a residential street a slatted curtain reads as commercial. Timber, full-view aluminium and flush steel panel doors are what people choose when the door is part of the elevation rather than a hole to close.

Cost, honestly

Across a typical single domestic opening, a manual steel roll-up sits at the bottom of the range and an insulated aluminium sectional at the top, with a gap of several times between them. Motorisation adds a broadly similar amount to either. Our price guide gives ranges by door type; the reason we do not publish a single figure is that opening size drives cost more than door type does, and openings vary far more than brochures admit.

Maintenance and repairs

Both need an annual look. Shutters fail at the guides, the barrel bearings and the bottom rail. Sectional doors fail at the springs, rollers, cables and seals. Neither is meaningfully cheaper to keep going — the difference is that shutter faults tend to stop the door entirely, while sectional faults often announce themselves first as noise or a door that runs crooked. We repair both, on any make.

A quick decision table

Warehouse, factory, loading bay: industrial roller shutter.
Shopfront that must be secure overnight: security or perforated shutter, the latter if you want the window display visible after hours.
Detached domestic garage, no headroom: roll-up garage door.
Garage attached to the house or converted: insulated sectional.
Coastal property, any of the above: aluminium, not galvanised steel.
Heritage or face-brick home where the door must look right: timber or woodgrain aluminium, tip-up or sectional.

Motorisation, and what load-shedding does to it

Both families take a standard operator, but they are not the same motor. A roller shutter uses a tube or side motor driving the barrel; a sectional door uses a rail-mounted operator pulling a trolley. Two things matter more than brand.

Balance before power. A motor is sized to move a balanced door, not to overcome a badly sprung one. Bolting an operator onto a door that is already heavy to lift by hand is the fastest way to burn one out. We correct the balance first, every time.
Battery backup is not optional here. With the schedule this country runs on, a door with no backup is a door you will eventually be standing outside in the rain. Every operator we fit comes with battery backup and a manual override release.

Ask for rolling-code remotes rather than fixed-code. A fixed code can be captured from the street and replayed later; rolling code cannot. We motorise existing doors of both types.

Where compliance decides for you

If the opening is a fire separation — a warehouse divided into compartments, a plant room, a shared basement — the choice is made for you. Only a fire-rated roller shutter carries a rating, and it has to be certified, installed to the certificate and inspected on a schedule. No garage door does this. If an insurer or a local authority has asked for a rating, the conversation ends there.

Similarly, an opening a forklift passes through several hundred times a day is a shutter opening. Panel doors and their tracks do not enjoy that duty cycle, and the repair bill will tell you so within a year.

Five mistakes we see most often

Ordering a stock size. South African garages built before the 1990s are rarely square. A stock door forced into an out-of-square opening leaves the daylight gap down one side that everyone notices afterwards.
Choosing steel at the coast. Within a few kilometres of the sea, galvanised steel will bleed rust at the fixings long before its time. Aluminium removes that failure mode.
Forgetting the swing space. Tip-up and side-hinged doors need clear ground in front. Measure it before you fall in love with the look.
Insulating a detached garage. If the garage stores a car and a lawnmower, put the money into a heavier gauge or better locking instead.
Skipping the annual service. Every expensive door failure we attend started as a cheap one somebody ignored — a dry guide, a frayed cable, a seal that had perished.

Common questions

Can a roller shutter be fitted to a normal house garage?

Yes, and it is very common. Fitted to a home it is usually called a roll-up garage door. It is the standard answer where there is no headroom for a sectional door.

Which is more secure?

A security-specified roller shutter, provided it has anti-lift brackets and the guides are properly fixed into the reveal. A sectional door with a locking bar into both tracks is close behind. An unbraced door of either type is not secure regardless of material.

Which lasts longer?

In similar conditions and with the same maintenance, roughly the same — well over a decade inland. The variable is not the door type, it is whether anyone services it and whether the material suits the environment.

Can you convert my existing door to the other type?

Usually, yes. Converting a tip-up to a sectional or a sectional to a roll-up is routine work; what changes is whether the existing frame and lintel can carry the new mechanism. Send us a photo of the opening and we will tell you what is involved.

The short version

Roller shutters buy you space, span and security. Sectional garage doors buy you sealing, quiet and appearance. Measure your headroom, decide whether the garage is part of the house, and check how far you are from the sea — those three answers will pick the door for you far more reliably than a brochure will.

What we need to quote you

Three numbers and one photograph: opening width, opening height, clear headroom, and a picture of the opening from outside. From that we can tell you which mechanisms actually fit before anyone talks about money. We manufacture at our own works in Tarlton, Krugersdorp and install through branches in Cape Town and George, so the company that answers the breakdown call in five years is the company that built the door.

Send us the measurements and a consultant will call you back, usually within two working hours.
