PVC windows FAQ: 12 clear answers

These are the questions customers ask us most often, in the showroom and on the phone, before replacing their windows. Short, clear answers with no small print.

1. How long does a PVC window last?

A quality PVC window, properly installed, lasts for several decades. The first thing that needs attention over the years is usually not the profile but the hardware and seals, which can be adjusted or replaced without changing the window.

2. Can PVC windows handle the Valencian sun?

Yes, if the profile is good. Quality profiles include UV stabilisers and steel reinforcement inside. Cheap profiles, on the other hand, can yellow or warp. Find out how to tell them apart in how to choose quality PVC windows.

3. Is building work needed to replace windows?

Usually no major work is needed. The old window is removed, the new one is fitted into the same opening and sealed. In most cases there is no need to touch tiles or repaint walls.

4. How long does installation take?

The installation itself is quick: a typical flat is usually finished in one or two days, depending on the number of windows. We give you the manufacturing lead time in your quote.

5. Do I need a permit to replace my windows?

In most municipalities a simple notification or declaration of minor works ("declaración responsable de obra menor") to the town hall is enough, but each ayuntamiento has its own rules, so check with yours. If you live in a building with a community of owners, also check whether the statutes require a specific colour or model for the façade.

6. Can I have one colour outside and another inside?

Yes. It is very common to use the colour required by the community outside and white, or a finish that suits your home, inside.

7. Why is there condensation on my new windows?

New windows are far more airtight than old ones, so household moisture (showers, cooking, breathing) no longer escapes through gaps. The answer is to air the room for a few minutes a day; the tilt position is perfect for this. If condensation appears between the panes, that is a glass defect and is covered by the warranty.

8. Double or triple glazing?

In Valencia's climate, 24 mm double glazing with low-E glass is enough for most homes. 32 mm triple glazing pays off if you have a lot of outside noise or a very exposed façade.

9. Can I add a shutter with the new window?

Yes. We can make the window with its own roller shutter and box, manual or motorised. Doing everything at once is cheaper and cleaner than two separate jobs.

10. Which opening type should I choose?

Tilt-and-turn is the most versatile for almost any room. Sliding is ideal when there is no room to open inwards, such as on balconies and terraces. See all the options in types of PVC windows.

11. Are PVC windows safe for health?

Yes. Current EU-made profiles are lead-free and comply with European chemicals regulations. We explain it in detail in are PVC windows toxic?

12. How do I find out what they will cost?

Measure the width and height of the wall opening and use our online price calculator: choose the window type, glazing, colours and extras and see the price instantly. To understand what drives the price, read the PVC window price guide.
