Why VentanaCosta
6 reasons to choose us across the Costa Blanca
Manufacturing and installing in Alicante since 2010. What sets us apart from franchised chains and resellers isn't marketing — it's our own workshop, in-house multilingual team, broad coverage and a signed warranty.
Our own workshop in Alicante
We cut Kömmerling, Salamander and Cortizo profiles in our own workshop. We don't resell — that's why we're 18-25% cheaper than chains with middlemen and we control every metre of aluminium or PVC that leaves for site.
4-language customer service
Spanish, English, Russian and German. 38% of our clients are foreign residents (British, German, Russian, Scandinavian) and we serve them in their language from the first call to the signed warranty contract.
+3,200 homes fitted
Since 2010 we have installed in more than 3,200 homes and 180 homeowners' communities across Vega Baja, northern Costa Blanca and Murcia. Apartments, seafront villas, penthouses, commercial units and full blocks.
10-year warranty in writing
Written decennial warranty on the profile + 5 years on Roto NX hardware + 2 years on perimeter sealing. Not a brochure: if condensation or any leak shows up, we come back at no cost until it's resolved.
Subsidies handled for you
We process NextGen IDAE (up to 80%), the personal income tax deduction (up to 60%), the regional IVACE Valencia line and municipal IBI rebates. We deliver before/after energy certificates and an itemised invoice ready to file.
Costa Blanca + Murcia coverage
Free site visit across the entire province of Alicante (Vega Baja, Marina Baja, Marina Alta, Alicantí) and Region of Murcia (Mar Menor, Cartagena, the capital). Our own team — no subcontracting.

Frequently asked questions
What people ask us most
10 real questions we get every week by phone, WhatsApp and form. If yours isn't here, write to us.
1. How much does it cost to replace windows in a home on the Costa Blanca?+
For a standard 70-90 m² apartment with 6-8 Kömmerling 70 AD windows: €4,500-6,800 including VAT and installation. Villa 100-150 m² with lift-and-slide door: €8,500-15,000. Premium first-line villa with Cortizo aluminium: €15,000-28,000. The final price depends on actual sizes, opening type, glazing and floor access (crane). Free site visit and fixed written quote.
2. What is the lead time from signing the quote to having the windows installed?+
10-14 working days of manufacturing in our Alicante workshop plus 1-2 days of installation. Typical total: 17-20 days from quote signing. During summer (July-August) it may extend to 25 days due to workload, and community projects of 80+ dwellings are scheduled in phases of 2-4 months with a calendar approved by the board.
3. What warranty do you offer on the windows?+
10 years in writing on the PVC (Kömmerling, Salamander, Veka) or aluminium (Cortizo, Schüco) profile, 5 years on Roto NX hardware and 2 years on perimeter sealing. If internal condensation appears in the double glazing (factory defect) or any leak from sealing, we return at no cost until it is resolved. Warranty backed by Asefave (Spanish Association of Light Façade and Window Manufacturers).
4. Which subsidies can I claim and how much do I recover?+
By stacking grants you can recover between 20% and 80% of the investment:
• NextGen IDAE: 40-80% if you demonstrate >30% energy savings (active until 31/12/2026).
• IRPF deduction: up to 60% of personal income tax, €15,000 base cap (Royal Decree-Law 19/2021).
• Generalitat IVACE (Valencia) or Region of Murcia: 35-40% additional.
• Municipal IBI rebate: up to 25%/year for 5 years.
We handle all the technical paperwork.
5. Which languages can you serve me in?+
We serve in Spanish, English, Russian and German from the first call to the signed warranty. 38% of our clients are foreign residents (British, German, Scandinavian, Dutch, Russian), so we keep multilingual staff who understand both the carpentry jargon and the nuances of the contract and the subsidy. No misunderstandings on sizes or quotes.
6. I'm a community president — how do you handle whole blocks?+
We have refurbished more than 180 communities across the Costa Blanca and Murcia (Habaneras, La Veleta, Acequión, Levante Benidorm…). The process: 1) façade technical visit and type A/B/C proposal per opening. 2) Fixed price per dwelling type + volume discount (12-18% on 50+ windows). 3) Coordination with your property manager and AGM approval. 4) Staged manufacturing and phased calendar (2-4 months). 5) Single energy certificate + invoice itemised per owner for individual subsidy claims.
7. Do you offer financing or deferred payment?+
Yes. We partner with Sabadell Consumer Finance and CaixaBank: up to 36 months interest-free (0% APR) on purchases from €1,500, and 60-84 month options with reduced APR for quotes above €8,000. Eligibility study within 24h with ID and pay slip or pension. We also accept bank transfer, card and bizum.
8. What maintenance do the windows need?+
Minimal. Once a year: vacuum the sliding tracks and wipe the frame and EPDM gasket with mild soapy water. Every 2-3 years: a drop of sewing-machine oil on the closing points of the Roto NX hardware. In very high salinity zones (first line), we recommend hosing down the aluminium every 6 months. That's it — no painting or varnishing needed.
9. Which brand should I choose: Kömmerling, Salamander, Cortizo, Schüco or Veka?+
It depends on use and budget:
• Kömmerling 70 AD: best-seller in Spain, optimal price/quality for apartments and communities.
• Salamander BluEvolution 92: top insulation, Passivhaus, Uw 0.7 W/m²K.
• Cortizo COR 70 RPT: aluminium for first-line villas with large openings and minimalist aesthetic.
• Schüco AWS 75: premium German aluminium with RC2/RC3 anti-burglary.
• Veka Softline: affordable option with certified German quality.
We recommend the right one for your home during the free site visit.
10. What does the installation process look like? Will it be a big mess?+
Fast and clean installation: 1-2 days for a full home of 6-10 windows. The crew arrives at 8:30 with protective material (plastic, blankets), removes a window, installs the new one, seals the perimeter with Sika foam and silicone, then moves to the next. No need to empty rooms — just move furniture back 1 m. At the end of the day we clean the glass and vacuum debris. You can keep living in the house during the works.
