We set up home cinema in Sant Joan Despí. We visit your property, assess the work, give you a clear price, and get started. The fuse box has ceramic fuses instead of modern circuit breakers. The fuse box lacks a residual current device (RCD) or only has a main one protecting all circuits. RCDs trip frequently for no apparent reason, indicating they are old. The fuse box has fewer than 4-5 circuits for a whole home. The regulation requires a minimum of 5 circuits (lighting, general sockets, kitchen, washing machine, bathroom, and air conditioning). The fuse box is overloaded and has no space for adding electric car chargers or other modern equipment.

How we work

Call us, message us on WhatsApp, or request your quote online – we'll reply in under 10 minutes during working hours. After an initial assessment, the electrician will provide a fixed written quote detailing labour and materials. No work will begin without your prior approval, and the agreed price will not change unless unforeseen issues arise that you authorise. You will receive a fixed written quote before work begins, with a clear breakdown of labour and materials.

When to call for home cinema in Sant Joan Despí

The RCD protects people. It detects the difference between the current entering and leaving the installation. If this difference exceeds 30 milliamps, it means something or someone is earthing current, and the RCD trips in less than 30 milliseconds. This is what prevents electrocution when a fault in the washing machine causes the metal casing to become live and you touch it. Both components are in all modern fuse boxes but protect different things. The circuit breaker, also called an automatic switch, protects against overloads and short circuits. If you connect too many appliances to one circuit or if two wires touch due to a fault, the circuit breaker trips and cuts off power. Its function is to protect the installation's wiring and prevent fires. A highly requested upgrade today is combining motorised blinds with an integrated roller mosquito net in the same housing. This allows both the blind and the mosquito net to be operated independently, both hidden when not in use. It is the standard solution in modern new builds. For renovations of existing homes, it requires replacing the entire housing with a new, deeper one to accommodate both systems.

Materials and brands

If the blind slats are cracked, discoloured, and brittle (typical of blinds over 25-30 years old exposed to sun), repairing them piece by piece becomes uneconomical. Replacing the entire blind with a modern model costs two to three times more than just changing the cord. In return, you get another 25-30 years without problems. Modern slats are injected and filled with polyurethane, much more insulating than the old hollow ones, thus improving thermal insulation. And you can request factory-integrated motorisation. 30 days on repairs. Somfy motors with a 5-year official manufacturer warranty. Integration is done via an app. Download the manufacturer's app, connect the device to your WiFi, and then add it as an associated device via Google Home or Alexa. Once done, you can use commands like 'turn off the living room light' or 'raise the kitchen blind', and it works.

Indicative price

The price for home cinema setup in Sant Joan Despí typically ranges between €74 and €999. The final amount depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. It begins with a technical visit from an authorised electrician who diagnoses the fuse box and installation. They measure the actual wire gauge, identify overloaded circuits, and detect any existing earth leakages. They provide a fixed quote with a breakdown of costs. Call us, message us on WhatsApp, or request your quote online – we'll reply in under 10 minutes during working hours.

Frequently asked questions

How long does a full fuse box upgrade take?
For a standard 80-100 m² flat with 5-7 circuits, between 4 and 8 hours. For large houses or properties with more circuits, it can take a full day.
Is a power cut necessary?
Yes, throughout the entire job. We schedule it during working hours (9 am to 2 pm) to minimise disruption. If you have critical equipment, we will coordinate separately.
What is a 'boletín' and what is it for?
It is the official document signed by an authorised installer, certifying that the installation complies with the REBT (Low Voltage Electrical Regulations). You need it for the electricity company and your insurer.
Can I add circuits without changing the whole fuse box?
Yes, sometimes, if the existing fuse box has space and the overall installation can support it. We will assess this during the initial visit.
Do you work with an authorised installer?
Yes, all interventions requiring a 'boletín' are signed by an authorised installer registered in the Valencian Community.
