No signal. Lost channels. One television working while the bedroom set breaks up. These are the calls we deal with around Finchley every day. We get more demand for aerial repairs than new installations. A failed power supply or corroded cable joint is enough to stop your viewing. We put a meter on the system before we recommend buying anything.
We bring 25 years' experience to aerial repairs across N12, N2, N6 and NW11. Tell us if the picture drops in wind or rain, which rooms are affected and when it started. Call us free on 0800 206 2385, Mon–Sat 8am–7pm. We offer same-day service where possible and a clear price before work starts.
Start with what the television is doing
When every television loses reception together, we start with the shared feed and its power supply. When one room fails, we check that room's flylead, socket and cable branch. When several channels disappear together, we check their multiplex. Those details give us a useful testing order. The meter supplies the evidence.
Rain sends us looking for split cable jackets and water inside external joints. Wind sends us looking at loose cable, moving brackets and chimney lashings. We inspect the whole route involved. Replacing a wet plug leaves the next downpour free to fill it again if the cable above still admits water.
A repair visit starts with measurements
We check signal level, MER and BER across the available multiplexes. MER measures the quality of the digital signal; BER records errors in the received data. Your television's strength bar leaves out much of that story. A strong reading alongside poor quality still produces a broken picture.
We compare the incoming aerial feed with readings after the amplifier, splitter and affected sockets. That lets us narrow down the damaged section. We explain what failed, show you the proposed repair and give you a fixed written quote. We only start the agreed work once you approve it.
The small parts that stop a whole system
Loose centre conductors, corroded connectors, failed amplifier supplies and tired wall plates all earn their place on our checklist. We check amplifier power before condemning the aerial on the chimney. We also check gain: excessive amplification overloads equipment and ruins reception. Turning a booster up is no substitute for testing.
Here is a typical Finchley repair scenario: the lounge works, the extension does not, and the owner expects a roof job. We test both outlets and the splitter feeding them. If the loss starts on the extension branch, that is where we repair. The sound roof aerial stays in service.
Cable repairs built for the next downpour
Sunlight and movement take their toll on old external coax. Once the outer jacket cracks, water follows the cable into connectors and equipment. We trace the damaged run and explain how much needs renewing. For replacement runs we use WF100 screened cable, secure it properly and weatherproof outdoor connections.
Victorian terraces in Muswell Hill and Highgate often have aerial wiring threaded through several rounds of alterations. We check routes before pulling cable. We agree where a new run will go, keep it clear of sharp edges and leave enough support to stop it knocking against brickwork in the wind.
Loose aerials, chimney lashings and storm damage
We inspect the mast, brackets, lashings and aerial itself before deciding what to retain. A sound aerial on a shifted bracket needs secure mounting and measured alignment. Broken elements or badly corroded supports need replacement. We explain the condition of each part so you know what your repair covers.
Across Hampstead and Golders Green, neighbouring roofs do not tell the whole reception story. We measure Crystal Palace reception at your property and assess the Alexandra Palace relay where appropriate. The relay carries a smaller channel selection. We explain that difference before changing the aerial's direction. Unsafe chimneys need building repairs before we attach equipment.
Interference needs its own test
We check for 4G/5G interference when the measurements point towards mobile signals entering or overloading the system. We compare reception with suitable filtering and place a required filter ahead of the equipment it needs to protect. We also inspect screening, because a poor lead lets unwanted signals straight into the television.
A filter will not mend a waterlogged cable. An extra amplifier will not rebuild damaged broadcast data. We keep the repair tied to the test results, then repeat the measurements after the work. We check pictures and sound across the multiplexes before handing the system back.
Flats, mansion blocks and booking your repair
In Hendon and Colindale mansion blocks, we first establish who owns the aerial feed. Ask whether neighbours have lost the same channels. Shared failures need access to communal equipment and authorisation from the managing agent. We arrange that access before adjusting a building's distribution system.
Before calling, try a known-working removable flylead and check the television's input. Leave roof equipment alone. Avoid repeated retunes during a signal failure: they erase channels without repairing reception. Call 0800 206 2385 with your postcode, symptoms and access details. We explain the visit and price arrangements before booking.
