Guardamar del Segura is known for its vast pine forest over the dunes, its beaches and the mouth of the Segura river. It is a second-home destination with a mixed clientele: Spanish families from inland and from Madrid, and expats who buy an apartment or villa in the urbanisations near the coast.
The setting of dunes, river and sea makes humidity a factor to control on every job. We pay particular attention to waterproofing terraces and roofs, treating rising damp on ground floors and commercial units, and ventilating bathrooms and kitchens. We replace worn frames and fittings with salt-resistant materials.
The most common project is a full refresh of a second-home apartment: open kitchen, walk-in shower bathroom, hard-wearing floors and efficient air conditioning. We use low-maintenance finishes designed for homes used heavily in summer and left closed for part of the year.
In the villa and bungalow urbanisations we carry out full renovations, porch enclosures, pools and outdoor renovations. The good climate invites outdoor living, so we give prominence to terraces, porches and solariums with paving and protection suited to the area's sun and wind.
A good share of owners live away from Guardamar for much of the year. We manage the project remotely with a fixed-price quote, regular photo reports and communication by email and video call, so you follow progress without travelling. For international clients, English-speaking communication makes the whole process easier.
We handle the licence with Guardamar del Segura town hall. Interior renovations go by responsible declaration or minor works, while extensions, pools or facade changes need a major works licence and a technical project. We take care of all the paperwork so the job starts in order.
Every renovation is delivered on price and on time, with a final clean, certificates and a 2-year guarantee. We also work in Torrevieja, Santa Pola and Ciudad Quesada, to the same standard, with particular attention to damp control.
