A gate that opens and will not close, a motor that hums and does nothing, remotes that stopped working after a power cut, or a manual gate you want automated. Tell us whether it slides or swings and send a photo of the motor, and you get a free quote before anyone comes out.
Electric gate work in the Algarve covers repairing motors, control boards, photocells, remotes and racks on sliding and swing gates, automating gates that are currently opened by hand, and servicing the ones that still work. Most faults here are not the motor: they are safety sensors, corrosion and a gate that no longer runs level. Handyman Algarve quotes electric gate repair and automation in the Algarve for free, in English or Portuguese.
What usually goes wrong
Photocells. A blocked or misaligned beam stops the gate closing. Cheapest fault on this list and the most common.
Remotes and receivers. Flat batteries, a receiver that lost its memory after a surge, or a remote that needs reprogramming.
The rack and pinion on a sliding gate. Sand, grit and rust wear the teeth, and a worn rack makes a noise long before it fails.
Wheels, rollers and the track, when a sliding gate drags or lifts. This is a gate problem the motor then gets blamed for.
Water in the motor housing or the control box, which is what winter rain does to a seal nobody has looked at in ten years.
Swing gate arms and hinges that have dropped, so the leaves no longer meet and the motor is fighting geometry.
Supply faults, from a tripped circuit at the house to a cable damaged by roots or by a trench dug for something else.
A gate motor that has rusted where it sits
Cut the power at the house before touching anything: a gate motor is mains equipment sitting outdoors.
Use the manual release so the gate can be opened by hand while the fault is dealt with, and check the release still moves freely.
Look at where water reaches the unit. Rain running off a pillar into an unsealed housing is the usual cause, and no repair lasts unless that is fixed too.
Photograph the motor, the rack and the label with the make and model, since that decides whether the part exists or the unit is replaced.
Automating a gate that opens by hand
Three questions decide whether it is simple or not. What does the gate weigh and how long is it, which sizes the motor. Is there power at the gate, because a drive of thirty metres may mean a trench and armoured cable, and that is often the largest item on the quote. And is the gate itself in good enough condition to automate, because a motor applies the same force at the same speed thousands of times, and it will find every worn hinge and every sagging leaf. A gate that is stiff by hand does not become smooth with a motor: it becomes a motor with a short life. Where the gate needs work first, that gets said before the motor is quoted, not after.
Sliding or swing, and why it matters here
A sliding gate needs a clear run alongside the wall for its whole length, and it needs a level track, which is why it suits flat driveways and wide entrances. Swing gates need space to open into and a drive that does not rise steeply just inside the gate, since a leaf that fouls the ground is the classic cause of arm and hinge failure. Many Algarve properties sit above the road on a rising drive, and that is exactly the case where an underground swing motor or a sliding gate solves a problem that a surface arm will keep having. The decision is made at the gate rather than from a catalogue.
What determines the price?
For a repair, as of 2026, it is what has failed and whether the part is a stock item: photocells, a remote or a receiver are small, a control board is more, and a motor is the top of the range. Age matters as much as the fault, since a discontinued unit can mean the sensible repair is a new motor of a different make with new fittings. For automation, it is the motor sized to the gate, the power supply to the gate position, the fitting, and the safety kit, which is not an optional extra. Battery backup, an intercom, a keypad or a second remote are priced alongside so the whole picture is visible at once.
A photo of the motor and its label, plus whether the gate slides or swings and roughly how long it is, is usually enough to quote a repair without a visit. See how it works for the process from request to finished job.

Frequently asked questions
How do I open an electric gate manually?
Every automated gate has a manual release, and finding it before you need it is worth five minutes. On a sliding gate it is usually a key operated lever or a cover on the motor housing that disengages the pinion from the rack. On swing gates the release is on each arm, so both sides have to be freed. Turn the key, move the lever to the release position, then push the gate by hand. Remember to re-engage it afterwards, because a gate left in manual will not respond to the remote and looks exactly like a failed motor.
What does it cost to automate an existing gate?
It is quoted as three parts: the motor kit sized to the gate, the electrical supply to the gate position, and the fitting. The gate itself decides the motor, because weight, length and whether it is sliding or swinging change the unit. The supply is what people underestimate, since a gate at the end of a drive may need a trench and armoured cable back to the house. As of 2026 the quote separates those three so you can see where the money is, and it is free.
Why does my gate open but not close?
Nine times out of ten it is the safety photocells. They are the two small sensors facing each other across the opening, and if their beam is broken or misaligned the control board refuses to close, which is exactly what it is designed to do. Look for a spider web, a plant, a parked car, or a lens fogged with dust. Also check whether one has been knocked out of alignment, since a few millimetres is enough. If the cells are clear and it still refuses, it is the board or the wiring to the cells.
How long does a gate motor last?
A good motor lasts many years, and what kills them early here is rarely the motor itself: it is water and grit. Rain running down a pillar into an unsealed housing, sand in the rack of a sliding gate, and a foundation that has settled so the gate no longer runs level all shorten the life of a motor. On a coastal property, salt air adds corrosion of the rack, the pinion and the fixings. Motors that are cleaned, greased and kept level outlive the ones that are simply left alone.
Can a gate be opened if there is a power cut?
Yes, with the manual release, and that is the only reliable answer unless a battery backup is fitted. Battery backup is a small addition at installation and a common retrofit, and it is worth it for a property where the gate is the only vehicle access. What is not worth relying on is the remote, because it powers the transmitter and not the motor. Anyone who leaves a car inside a gated drive should know where the release key is kept.
What safety features should an automated gate have?
Photocells across the opening so it cannot close on a person or a car, force limiting on the control board so an obstruction stops the gate, a flashing light or warning while it moves, and mechanical stops so a sliding gate cannot come off its rack. Anything with heavy leaves near a public path also wants edge protection. A gate that closes hard on an obstruction without stopping is not a nuisance, it is a fault to fix, and it is the first thing checked on a service visit.
