Dénia, capital of the Marina Alta, blends a lively port and marina, a historic old town beneath the castle and kilometres of coast between Las Marinas and Les Rotes. That variety shows in the renovations: beach apartments in Las Marinas, town flats near the market and port, and villas with pools on the slopes of the Montgó and at Marquesa or La Sella. Each type needs a different approach, and we tackle them all to a fixed price.
The Montgó is Dénia's great backdrop. Its lower slopes hold villas owned by Spanish and international buyers seeking views, quiet and a pool. We renovate these homes with efficiency in mind — insulation, climate control, large windows — and take care over how they sit on the plot: porches, terraces and pool form one unit with the house, making the most of the area's exceptional climate.
Second homes are central to our work in Dénia. Many owners spend only part of the year here and need a contractor they can trust to manage the build in their absence. We offer a written fixed-price quote, an English-speaking project manager and regular photo reports, so you can renovate your Las Marinas flat or your Montgó villa from northern Europe.
Pool construction and renovation is a much-requested speciality in Dénia. We build bespoke concrete pools, renew old shells, replace coping and lining, and modernise filtration with efficient equipment. We integrate the pool with terraces, outdoor showers and seating areas, because in Dénia the outdoors is enjoyed much of the year.
We carry out full and partial renovations turnkey: new plumbing and electrics, kitchens and bathrooms, porcelain floors, paint and carpentry, all under one responsible manager. For an 80 m² apartment the typical timescale is 6 to 8 weeks; for a villa, depending on scope, 2 to 5 months. We work with a choice of finishes and a fixed price that does not change apart from alterations you approve.
We cover all of Dénia and the neighbouring areas of Jávea, Benissa and Calpe. Every project is handed over with a written 2-year guarantee and the backing of more than 15 years renovating on the Costa Blanca. From the free site visit to handover, you have one point of contact and the reassurance of a price agreed from the outset.

Frequently asked questions about renovating in Dénia
Do I need a building licence from Dénia town hall?
An interior renovation in Dénia is handled as a declaración responsable (minor works) with Dénia town hall. Pools, extensions and structural changes need major works and a project. We manage whichever licence applies for you.
Do you build pools in Dénia?
Yes. We build bespoke concrete pools and renovate existing shells: coping, lining, efficient filtration and integration with terraces and seating areas. Ideal for villas on the Montgó, Marquesa and La Sella, making the most of the local climate.
Do you manage second-home renovations remotely?
Yes. Many Dénia owners live away part of the year. We assign an English-speaking project manager, coordinate by email and video call and send photo reports. You approve finishes and stages without travelling.
