A single point of contact for studying works and maintenance in buildings: from a specific incident to a planned intervention to present to the owners.
Request an assessment of this serviceQuotes to present at the owners' meeting
Separate line items, measurements, alternatives and scope to make comparison easy. Tell us if you need to separate urgent works from improvements.

Diagnosis of leak sources, repair of junctions, review of water drainage and work on shared networks.

Documentation of the work
Request a quote, planning, payment terms and documentation applicable to the works and installations.
Planned maintenance
Groups incidents by zone and priority to plan orderly work, avoiding mixing an urgent repair with a full renovation.

Barcelona and metropolitan area · Scope, availability and conditions are confirmed in the quote.
ELECTRICAL INSTALLATIONS IN BARCELONA
Make sure your installation meets what you need.
Electrical renovation for homes, premises and common areas. Before proposing new points or a board, the condition of the installation and the planned loads must be reviewed.
Request an assessment of this serviceBoards and circuits
Circuit study, protection, earthing and load distribution. Avoid extending uses without checking existing capacity.
Home renovations
Light points and sockets, kitchen, air conditioning and provision for future equipment. Coordinate chases and conduits before closing walls.
Shops and offices
General and product lighting, workstations, machinery and emergency needs depending on the use of the premises.
Owners' communities
Staircase and walkway lighting, timers, presence detection and review of common installations according to scope.
Do you need a CIE or electrical certificate?
The documentation depends on whether it is a new installation, a modification or an existing supply. The case should be checked before quoting.
Execution and certification
Regulated works and their certificates must be carried out by qualified or authorised professionals or companies, as applicable. No certificate can be issued without the necessary checks.
To prepare an assessment
Send photos of the board without opening covers, the use of the property and the planned equipment. Do not handle conductors or protections to take photos.
Barcelona and metropolitan area · Scope, availability and conditions are confirmed in the quote.
TERRACES · ROOF DECKS · ROOFS
The solution starts by finding where the water comes from.
Repair of terraces, walkable roofs and community roof decks. Not every stain needs the same intervention: we check the substrate, slopes, joints and drainage.
Request an assessment of this serviceLeak diagnosis
Study junctions with walls, parapets, drains, joints and special points. The interior stain can appear far from the water entry point.
Waterproofing
Choose a system compatible with the substrate, use and final finish. Base preparation and edge finishing are part of the work.
Flooring and slopes
Assess ponding, loose pieces, slopes and the condition of existing layers before replacing only the visible finish.
Community terraces
Distinguish private use, common elements and the scope to be approved by the owners. Avoid contracting a solution without defining authorisations.
Before covering up damp
Sending photos of the inside, the outside and of when the problem appears helps plan the inspection. Remote assessment does not replace a diagnosis.
Works compatible with use
Plan access, removal of materials, protection of homes and weather conditions. Drying and curing depend on the system chosen.
Finish and checks
Define flooring, junctions, drainage and checks suited to the work; keeping drains and joints clear is part of later care.
Barcelona and metropolitan area · Scope, availability and conditions are confirmed in the quote.
AIR CONDITIONING · HOME AND BUSINESS
Split or ducted. The solution that fits your space.
Installation and renewal of air conditioning for homes, shops, offices and hospitality. Selection depends not only on square metres: use, insulation, sun exposure and occupancy also matter.
Request an assessment of this serviceSplit and multi-split
An option to air-condition one or several rooms when the routing and unit location allow it. Check drainage, noise and maintenance.
Ducted air
Distribution through a false ceiling and grilles. Check available height, routing, return air, insulation and access to the unit.
Commercial air conditioning
Assess split, cassette or ducted systems according to layout, capacity, opening hours, activity and premises. Air conditioning does not replace the ventilation required.
Pre-installation during the renovation
Before ceilings are closed, define the route for pipes, drains, power supply, return air and maintenance access points.
What the proposal must include
Equipment model and performance, installation, supports, planned routes, drainage, electrical and masonry works, commissioning and exclusions.
Outdoor unit and permits
Check the façade, common elements, building protection and noise before choosing a location. Installation on any balcony is not automatically valid.
Equipment replacement or new installation
Tell us whether there is a pre-installation and send photos of the units and visible routes. Reusing them requires checking compatibility and condition.

// CLIENT GUIDE
How to hire a renovation in Barcelona
A clear six-step process, so you always know what is being done, how much it costs and what you need to decide.
1. Technical visit
We measure the home or premises, check the condition of the installations and detect damp or structural problems before quoting.
2. Itemised quote
Each line item is shown separately (demolition, masonry, plumbing, electrics, finishes), so you can compare fairly with other quotes.
3. Permits and documentation
Depending on the scope of the works, an Assabentat, a Comunicat or a licence may be needed. We check this before starting, not halfway through the works.
4. Written contract
The contract covers the timeline, payment terms, materials, guarantees and public liability insurance. No verbal agreements.
5. Execution and follow-up
We work with a trade-by-trade schedule and a site manager who keeps you informed of progress and of any change before making it.
6. Handover and guarantee
We review the finished works with you, hand over the final documentation and put the guarantee for each job in writing.
// FLATS AND PREMISES IN BARCELONA
Common problems in renovations of old buildings
What we usually find when opening walls and floors in Barcelona, and how it is solved before the works are closed.
Damp in old flats
In old buildings in Barcelona, rising damp at ground-floor level and leaks from terraces or downpipes are common. The cause must be treated before painting.
Old electrical and gas installations
Many flats still have wiring without earthing or with insufficient power for kitchens and air conditioning. Renewing the installation is one of the most important items in a renovation.
Bathroom and kitchen ventilation
Without an adequate extraction duct, condensation and mould appear. We plan this during the design of the renovation so that it does not fail once finished.
Floor slabs and partition walls
Before removing a partition wall, check whether it is load-bearing. In buildings over a hundred years old, the structure requires a prior technical assessment.
Noise and living alongside neighbours
Works in communities require notifying neighbours and respecting noise hours. We schedule noisy work within the permitted slots and communicate the timetable.
Construction waste
Rubble must be taken to an authorised waste manager. We take care of the skip, transport and paperwork so that you have no responsibility for it.

Regulations and Permits in Barcelona
We handle all the paperwork. These are the regulations in force from Barcelona City Council (2026) that we manage for your peace of mind.
1. Assabentat d'Obres (works notice)
Mandatory free procedure for minor works (painting, floors, tiling) that do not alter the layout or structure.

In Barcelona, noisy works are only permitted Monday to Friday, 8:00–20:00. Weekends are prohibited.

The City Council requires a deposit to ensure rubble is taken to an authorised landfill (Decree 89/2010).
