Introduction
Renovating the electricity in your home is an essential step to ensure both the safety of occupants and the compliance of the dwelling with regulatory standards. Whether as part of a partial or complete renovation, it is essential to rely on a qualified professional to intervene effectively and without compromising quality. MASCOSY Electricité, a local company in Istres, supports homeowners in all their electrical projects, from the initial audit to the validation of work according to the NFC 15100 standard.
Why Is It Necessary to Renovate the Electricity in a House?
The electricity in an old dwelling generally no longer meets current safety and comfort requirements. The obsolescence of installations, wear of materials, and the evolution of equipment needs (heating, multimedia, home automation, etc.) make regular upgrades essential. An outdated installation presents high risks of short circuits, fires, or electrocutions, as highlighted in the annual report of the National Observatory of Electrical Safety (ONSE).
In France, it is estimated that around 7 million homes have an electrical installation with at least one critical anomaly (source: promotelec.com). To ensure the safety of occupants and comply with regulations, it is therefore essential to plan a renovation as soon as signs of wear or obsolescence appear.
When to Consider a Complete or Partial Electrical Renovation?
Several situations justify an intervention on the electrical installation of a dwelling:
- Presence of defective or non-compliant outlets or switches
- Outdated electrical panels lacking differential circuit breakers
- Absence of grounding or protection devices against overcurrents
- Modification of the internal distribution during renovation work
- Desire to improve the comfort and safety of occupants
Property diagnostics, mandatory during the sale or rental of a property, can also reveal the need for compliance or correction of anomalies. At MASCOSY Electricité, each intervention begins with a precise analysis of the existing situation, followed by recommendations tailored to the context of the dwelling.
The Standards to Follow: NFC 15100 and Installation Safety
The NFC 15100 standard governs all technical requirements related to electrical installations in housing. It notably imposes:
- The presence of 30mA differential devices for personal protection
- Balancing of circuits and separation of uses (lighting, outlets, appliances)
- Installation of a compliant electrical panel, easily accessible, with clear identification of circuits
- Compliance with distances and safety volumes in wet rooms (bathrooms, kitchens)
Failure to comply with these requirements can lead to a refusal of conformity (Consuel) during the sale or rental, exposing the owner to major risks in the event of a disaster. To ensure regulatory compliance, MASCOSY Electricité carries out all work in strict adherence to the NFC 15100, with systematic validation of installations.
Planning the Work: Approach, Quote, and Organization
An electrical renovation, whether partial or complete, requires rigorous organization to limit disruptions in the daily lives of occupants. MASCOSY Electricité offers transparent and structured project management, including:
- Conducting an initial on-site diagnosis
- Providing a detailed and transparent quote within 72 hours
- Planning interventions according to the owner's availability
- Clear information on the duration of work and any power outages
- Waste management and site cleaning at the end of the intervention
To obtain a personalized and free quote, it is recommended to prepare the housing plans, the list of equipment to be installed or protected, and any access constraints in advance.
What Work to Include in an Electrical Renovation?
An electrical renovation can include several types of services, depending on the initial state of the installation and the expectations of the owner:
- Replacement or addition of outlets and switches
- Installation or renovation of an electrical panel
- Grounding or correction of grounding defects
- Installation of an indoor or outdoor lighting system
- Modification or balancing of the TGBT for tertiary premises
- Compliance and corrections following a property diagnosis
- Lifting of reservations for sale or rental
