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. The motor often takes the blame for a fault that sits somewhere else: the 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. The cheapest fault on this list to put right, and the first to check.
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 board in the house before touching anything, and disconnect the backup battery if one is fitted: a gate motor is mains equipment sitting outdoors, and on battery it will still drive the gate.
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.
What safety rules apply to an automated gate?
A gate with a motor on it is machinery in law, and a gate you push by hand is not. Both Directive 2006/42/EC, the instrument in force, and Regulation (EU) 2023/1230, which replaces it on 20 January 2027, use the same test: a drive system other than directly applied human effort. Both also cover an assembly that only works once it is installed in a building or a structure, which is what a gate is. That is the part people miss when they automate a gate they already own. The motor does not only make the gate easier to open, it moves the gate into rules it sat outside the day before.
Under those machinery rules the CE mark on a gate or an operator is the manufacturer's own declaration, and not a certificate issued by anyone else. No door or gate appears in the high risk annex of either instrument, so the route is internal checks with no notified body involved: the manufacturer meets the essential health and safety requirements, holds the technical file, supplies the instructions, draws up the declaration of conformity and affixes the mark. The instructions and the declaration are worth asking for and worth keeping, because they are what a repair years later gets quoted from.
Neither instrument contains the word photocell. What they require is written as a principle instead. Moving parts must be designed so that contact which could cause an accident is prevented or, where a risk remains, be fitted with guards or protective devices. A protective device has to be built into the control system so that the moving parts cannot start while a person is within reach, so that nobody can reach them while they are moving, and so that the absence or failure of one of the device's own components prevents starting or stops the moving parts.
A gate that has gone dead after a photocell failed outright is not carrying a second fault on top of the first: that is the last of the three limbs above, a missing or failed component stopping the gate. A beam that is merely blocked or knocked out of line is the other case, and it stops the gate closing rather than opening.
Both instruments also require that a guard or a protective device is not easy to by-pass or render non-operational. Disconnecting the sensor to get the gate moving again is not a temporary fix: it leaves the gate free to close on whatever is in the way, which is the outcome the requirement exists to prevent. The Directive reached Portuguese law through Decreto-Lei n.º 103/2008, since amended.
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.
Garage doors, and whether an existing one can be automated
A garage door is the same trade as a gate and a different machine. The four types that turn up here are the sectional, whose panels run back along the ceiling; the up-and-over, which tilts out and up in one piece; the roller, which winds into a drum above the opening; and the side-hinged pair, which is a gate that happens to be on a garage. Each one fails differently and each one automates differently, which is why the type is the first thing to establish.
An existing door can usually be automated, and the question is where the motor gets to push from. A sectional or a roller door takes an operator above the opening and is usually straightforward. An up-and-over needs the right kit for its mechanism and enough headroom for the arm. A side-hinged pair takes gate arms, and everything on this page about swing gates applies to it. What rules a retrofit out is almost never the motor: it is a door that no longer runs freely by hand, a spring or counterweight at the end of its life, or a frame that has moved.
Three measurements decide a garage door, and width is the one people reach for first. The number that matters is the clear structural opening rather than the door leaf, and for a sectional door the two that decide whether it fits at all are the headroom above the opening, where the panels have to run back, and the side room for the tracks. In an older garage a beam sitting immediately above the opening can leave too little of either, which is why those two are measured before a door is chosen. Width itself is set by the vehicle, the mirrors and the angle you enter at from the street, so a door that is generous on paper can still be a squeeze from a narrow lane.
On safety the position is the same as for a gate. Putting a motor on a door that was hand operated moves it into the machinery rules it sat outside the day before, and the protective devices are part of the job rather than an upgrade. Two things are worth adding for a door specifically: know where the manual release is and how it works before you need it, and use it with the power off at the house, as on a gate, and with the door down, because a door whose spring or counterweight has failed can fall the moment the operator lets go of it; and never disconnect a sensor to get a door moving again.
What moves the price is the same short list as for a gate, in a different order: the type and size of the door, whether it is a repair, an automation of what is there or a new door, the operator sized to the weight, whether there is power at the ceiling above the opening, and the safety devices, which are part of the job and not an extra. A spring or counterweight at the end of its life is what turns a quote for automation into a quote for two things, which is why it is looked at before the operator is priced.
Handyman Algarve arranges garage door repair and automation in the Algarve, and the quote is free. If you are still deciding, a photo of the door from inside the garage with the ceiling in frame answers most of the questions above before anyone comes out.
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 one. Find it before you need it. Cut the power first, at the house or at an isolator you can reach without opening the motor housing, and disconnect the backup battery if one is fitted, because on battery the motor can still drive the gate. On a sliding gate it is usually a key operated lever; on swing gates there is one on each arm and both must be freed. Re-engage it afterwards: a gate left in manual looks 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. The quote separates those three so you can see where the money is, and it is free.
What is the cost of an automatic garage door?
It depends on whether it is automating the door you have or a new door with an operator. For a sectional or an up-and-over, the size of the opening, the type of door, the operator sized to its weight and the safety devices set the price, and on an existing door in good order the automation is the cheaper job of the two. A failing spring or counterweight turns it into a quote for two things. Send the opening size and a photo, and the quote is free.
Why does my gate open but not close?
The safety photocells come first. 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 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. A motor cleaned, greased and kept level outlives one left alone.
Can a gate be opened if there is a power cut?
Yes, with the manual release, used with the mains off at the house and the backup battery disconnected. It is the only reliable answer without battery backup, which is a small addition at installation and worth it where the gate is the only vehicle access. The remote is not worth relying on, because its battery powers the transmitter and not the motor. Anyone who leaves a car inside a gated drive should know where the release key is kept, before the first power cut rather than during it.
Can you make an existing garage door automatic?
Usually yes, and the door decides how, not the motor. A sectional or a roller door takes an operator fitted above the opening. An up-and-over needs a kit made for its mechanism and enough headroom for the arm. A side-hinged pair takes gate arms. What rules a retrofit out is a door that no longer runs freely by hand, a spring or counterweight at the end of its life, or a frame that has moved, and all three are cheaper to find before the motor is ordered than after.
What are the downsides of smart garage door openers?
Three that matter. A door you can open from a phone can be opened while nobody is watching it close, and the safety devices exist because a closing door does not know what is under it. The convenience depends on your internet and on a manufacturer keeping an app alive, neither under your control. And remote access is a way into the house, so it wants its own strong password and two-factor login. None of that argues against them, only for keeping the safety kit and knowing the manual release.
What safety features should an automated gate have?
A working installation has photocells across the opening so the gate cannot close on a person or a car, obstruction detection on the control board so it stops when it meets something, a warning light while the leaf moves, and end stops so a sliding gate cannot run off its rack. Heavy leaves, and leaves that swing over ground people walk on, are where a safety edge earns its place. A gate that closes hard without stopping is a fault to fix, not a nuisance.
Do the rules for electric gates change in 2027?
Yes, and a gate that is already installed is not affected. Regulation (EU) 2023/1230 applies from 20 January 2027 and repeals Directive 2006/42/EC on the same date. The Regulation's own transitional article says member states may not impede the further making available on the market of products that were placed on the market in conformity with the Directive before that date, so nothing about an existing gate has to be re-done. What changes is what a manufacturer must do for equipment placed on the market from then on, including keeping the documentation for at least ten years and giving safety information on paper wherever non-professional users are involved.
What does it mean if a gate is said to meet a standard?
A presumption, and only that. The Directive in force says it and the Regulation that replaces it repeats it: equipment built to a harmonised standard whose reference has been published in the Official Journal of the European Union is presumed to meet the essential health and safety requirements that standard covers. It is not an approval, and it is not a third party's certificate. So the useful question to an installer is not whether a standard is named in a brochure, but which published standard the equipment was built to, and whether the instructions and the declaration of conformity come with it.
