03 How we work

No surprises halfway through

What you can hold us to from the first call. Tap each point for the details.

01The price you sign is the price you pay

The quote itemises profile, glass, hardware, removal of the old window and installation. If anything changes when we measure, you will know before we manufacture, not at the end.

02We tell you which profile you don’t need

A flat in Valencia doesn’t need a passive-house profile. We compare Rehau, Gealan, Decco and MegaLine with you and recommend what makes sense for your climate and budget.

03Windows in the warehouse, not on a waiting list

The most requested MegaLine 600 sizes are in stock. If your opening fits, there are no weeks of production to wait for.

04We take the old one away and leave it clean

We remove the old window, install, seal and take the waste with us. All you do is open the door.

05We speak Spanish, English and Ukrainian

Ask in whichever language you are comfortable with: the person who answers is the one who handles your order.

What our clients say

A highly recommended company, attentive at every step. The windows are good quality and better priced than elsewhere. The fitters are very professional.
Andrés Alcaide
My problem was the constant noise outside my window: a bar and a railway line with electric and freight trains. After replacing the windows, the difference is incredible. It is much more comfortable now, no noise. I'm very happy!
Katerina Smitnova
Very good service by phone and WhatsApp from the start, and despite a complicated quote and measurements, everything turned out perfectly. Very experienced installers who don't waste time: they get on with the job and solve any issues very quickly. A very reliable company.
Francisco Ruiz
Very good quality windows and excellent service from the sales rep, always on top of everything. The installation went very well, and they came back to fix some finishing details without any problem. I appreciate how well and how quickly they responded to my needs. I will work with them again next time.
Claudia Ríos
Very professional and great work. You can also contact them with any question and they reply straight away and sort everything out. 100% recommended!

07 Questions

What people ask us every week

01Are measuring and the quote free?

The quote for your sizes is completely free. A technician’s measuring visit costs €50; if our team does the installation, that amount is deducted from the installation cost.

02How long until I get my windows?

Standard sizes in stock ship in 48–72 h. Made-to-measure windows take up to 40 days after the first payment and signing the contract. If an express order is possible in your case, production takes 15 days.

03Do you work all over Spain?

Yes, we deliver and install across mainland Spain, and we also ship to the Balearic Islands.

04Which profile should I choose?

For flats and renovations 70–74 mm is usually enough (MegaLine 600, Gealan S 8000, Rehau Euro-Design 70). For houses or noisy areas we recommend 80 mm or more (Gealan S 9000, Decco 82, Rehau Synego 80). We will explain it for your specific case.

05Can I buy just the window, without installation?

Yes. We sell to homeowners and professionals. Installation, if you need it, is signed under a separate contract.
