Frequently asked questions

Can’t find yours? Call us and we will explain.

How much does a full renovation cost in Mataró?

It depends on the size, the condition of the property and the finishes. That is why we visit your home for free and give you a fixed, itemised quote instead of a per-square-metre price that changes later.

How long does the work take?

As a guide, a bathroom takes two to three weeks, a kitchen three to four, and a full flat renovation two to four months. We give you the schedule in writing before we start.

Can I see the result before we start?

Yes. We prepare a 3D visualisation with the layout, materials and finishes so you can decide with confidence.

Do you handle building permits?

Yes. We tell you whether your project needs a prior notice or a licence from your town hall, and we prepare the paperwork.

Do you use your own team?

Yes. The work is carried out by our own team, coordinated by a single site manager who is your contact from start to finish.

Is there a fee for the visit and the quote?

No. The technical visit and the quote are free and without obligation.
