How long does a full installation in Cartagena take?+
From quote sign-off to handover: 10-14 working days of manufacture + 1-2 days of installation per home (average flat). Add 3-5 weeks for Historic Centre projects to handle the Municipal Heritage paperwork. For 50+ flat communities we plan blocks of 2-3 weeks each.
Does the on-site survey cost anything?+
No. On-site survey + fixed quote are free and no-obligation across all of Cartagena, Cabo de Palos, La Manga, Playa Honda, Santiago de la Ribera and nearby towns like San Pedro del Pinatar, Los Alcázares and Mazarrón.
Can you fit windows in my La Manga flat that won't rust in 3 years?+
Yes. The key is the QUALIMARINE certificate: a lacquering specifically designed for extreme marine environments with additional pretreatment and a coating thickness of ≥ 60 microns. Combined with stainless Roto NX hardware, we guarantee 25+ years without visible rust in La Manga. It costs a little more but spares you redoing the work in 4-5 years.
I live in a Modernist building in the Historic Centre — can you replace my windows?+
Yes, with permission from Cartagena's Municipal Heritage Office. We prepare a technical report with photo-montage, approved RAL specification and a traditional mullion pattern. We use wood-effect uPVC or aluminium lacquered in a historic colour. Typical approval time: 3-5 weeks.
Can you prepare the paperwork for Region of Murcia subsidies?+
Yes. We provide: itemised invoice by chapters, before-and-after energy certificate where required, installer's declaration, product datasheets and CE + QUALIMARINE marking. That gives you everything for NextGen IDAE Region of Murcia, IRPF, INFO and the Cartagena IBI rebate.
Why does it cost more in La Manga than in Cartagena city?+
For two reasons: logistics (single access road, slower transport, tower unloading by lift) and material (certified QUALIMARINE lacquering for extreme salinity costs 18-22% more than standard lacquering). The typical surcharge is +25% compared to an equivalent home in the Ensanche or Los Dolores.
How does payment work? Do you accept finance?+
We accept bank transfer, card and Bizum. Standard payment terms: 50% on signing and 50% on installation completion (not before). For larger La Manga or Mar Menor villa projects we can split into 3 milestones. If you need bank finance, we can recommend lenders with preferential rates for energy refurbishments.
What happens to my old rusted La Manga windows?+
We dismantle them, remove them and take them to an authorised waste facility in the Region of Murcia. The rusted aluminium is recycled. Removal cost is included in the quote — it does not appear as an "extra" at the end. If your homeowners' association needs a waste-management certificate, we provide it.
Which is better in Cartagena: PVC or aluminium windows?+
On the seafront PVC wins in most cases: salt air does not corrode it, it insulates better per euro spent (480-720 €/m² installed vs 620-1,150 €/m² for aluminium) and lasts 40+ years on the Mediterranean coast. Thermal-break aluminium (Cortizo COR 70 with QUALIMARINE coating) makes sense for very large openings and slim-frame sliding systems. We install both, plus mixed PVC-aluminium windows — we recommend the material based on orientation, floor height and opening size, not on a catalogue.
How much do PVC windows cost in Cartagena?+
As an installed reference in Cartagena: 480-720 €/m² with Kömmerling profiles, low-emissivity double glazing and Roto hardware. A 50-80 m² apartment with 5-7 windows usually comes to €5,000-7,000 (VAT included); a villa or bungalow with full glazing, €8,500-13,500. Measurement and a written quote are free, with no obligation.
Which PVC window brand is best?+
We fit German Kömmerling profiles (70 AD and 76 AD) with steel reinforcement and Roto NX hardware — the combination that performs best on the coast for wind resistance (up to class C5), water tightness E1200 (9A) and spare-part availability. For aluminium we work with Cortizo. Everything is CE-marked with a 10-year written guarantee.
How do you clean and maintain PVC windows by the sea?+
Frame and glass: warm water with neutral soap — never solvents, acetone or abrasive pads. On the seafront, rinse the salt off 3-4 times a year. Hardware: a drop of neutral oil on hinges and locks once a year. EPDM gaskets are maintenance-free and can be replaced in minutes if they ever lose elasticity.
What is the installation like and how long does it take?+
It starts with a free laser-measured survey. We manufacture to size and install: a typical home project takes 2-4 weeks from order to handover, with the installation itself done in 1-2 days and no wet works. We remove and dispose of the old windows, seal the perimeter and leave the home clean the same day.
Can PVC windows have roller shutters and mosquito screens?+
Yes. We integrate roller shutters with an insulated compact box (foam-filled aluminium slats), belt or motorised operation with remote and home automation, and roll-up or fixed-frame mosquito screens — including on sliding systems. Everything is made together with the window, in the same colour and under the same guarantee.
Do PVC windows insulate against noise and heat?+
That is their strongest point. With acoustic glazing 6/16/3+3 (Rw 42 dB) we have cut 65 dB of outdoor noise down to 23 dB indoors on the seafront. Thermally, the profiles we fit comfortably beat the required Uw ≤ 2.2 W/m²K and noticeably cut air-conditioning and heating bills.
Do I need a permit to replace windows or enclose the terrace in Cartagena?+
Replacing windows without altering the opening is minor works: a simple prior notification (declaración responsable) to Cartagena town hall is enough. Terrace enclosures depend on municipal rules and your community statutes. We prepare and file the paperwork in both cases.
What are glass curtains and how much does a terrace enclosure cost?+
Glass curtains are frameless tempered-glass panels that fold away completely: the terrace is enclosed without losing the view or the light. The price depends on linear metres, height and glass; after a free survey you get a fixed written quote.
What is a bioclimatic pergola and how much does it cost?+
A bioclimatic pergola is an aluminium structure with adjustable louvres that control sun and airflow, with optional rain and wind sensors. Combined with glass curtains it makes the terrace usable all year round. Price depends on size and options; survey and quote are free.
