Our work
Kitchen renovation in Castelldefels
We replaced the old fittings with new units, an extractor hood, oven and hob, for a more modern and practical kitchen.

Does your project need painting, lacquering, plasterboard, wood floors or doors?
We can help with that too: for this work we partner with Bucaros, painting and finishing specialists in Castelldefels. Ask us for a quote and we will coordinate it.

Frequently asked questions
Your most common questions about renovations
Do you handle the whole renovation?
Yes. We carry out the technical installations and coordinate the rest of the work, so you have a single point of contact from start to finish.
Do you also do partial renovations?
Yes. As well as full renovations, we update individual rooms such as bathrooms, kitchens or utility rooms, and smaller jobs such as replacing taps or sanitaryware.
How long does a renovation take?
It depends on the size of the space and the scope of the work. When we prepare your quote, we give you an approximate schedule.
Do I need a permit from the town hall?
It depends on the type of work and the municipality. We will advise you on the procedure that applies before we start.
Do you also take care of the electrics?
Yes. We are an authorised electrical installer, so we do the electrical part of the renovation ourselves, including the certificate when needed.
Which areas do you cover?
We work in Castelldefels, Gavà, Viladecans, Sitges, Baix Llobregat, Garraf and Barcelona. If your project is somewhere else, just ask us, with no obligation.
How much does a renovation cost?
It depends on the size, the condition of the space and the finishes you choose. We visit the home or premises and prepare a clear, no-obligation quote.
