Moisture before finishes
Moisture needs an on-site diagnosis: condensation, water ingress and a faulty system call for different responses. New cladding cannot replace fixing the cause.
Where we work
Luxury villa renovation in Gavà Mar
On the coast, lasting material quality depends on exposure, ventilation and maintenance. We consider the home, exterior areas and services together.
Exterior works in the estimate
Terrace, garden, shading and pool are separate work packages where included. Feasibility depends on the plot and applicable rules.
How much does a luxury renovation cost in Gavà Mar?
BCN YARD guide prices excluding VAT are the same across Barcelona and the wider province: Premium from €1,000/m², Luxury from €2,000/m² and Signature from €3,000/m². The final price is set in an itemised estimate after the site visit; it depends on the state of the services, the floor area, layout changes and, for houses, the facade, roof, garden or pool.
Frequently asked questions
Why are the walls of a house in Gavà Mar damp?
Most often damp rises from below: on the coastal plain the water is shallow, and walls without a barrier absorb it by capillary action. There is also condensation from weak ventilation and leaks through the facade. First the source is identified through readings and inspection, then the fix is chosen: injection, drainage, a ventilated plinth or a new roof.
Can you build a basement in a house in Gavà Mar?
Yes, if the geotechnical report shows the water is below the basement floor, or if the design is calculated for high water: waterproofing grade 5, drainage and pumps, or a watertight tank. In that case the basement costs noticeably more. It is decided by your plot's report, not by the house next door.
Can I prune the roots of a pine next to the house?
Thin lateral roots are cut cleanly; thick ones near the trunk are not touched without an arborist, because on sand the pine loses anchorage and can fall. Before the works the drains are surveyed with a camera and the roots at the foundation are marked. Felling needs the administration's authorisation and is raised before the estimate is signed.
