How Much Does It Cost to Replace Windows? Prices and Key Factors in 2026

One of the most frequent questions we receive is: how much will it cost to replace the windows? The honest answer is that there is no single price, because there are many factors that influence the final budget. But we can give you a clear orientation of the current price ranges.

General price range per window

The cost of a new window ranges between 300 and 1,200 euros per unit, including profile, glass, hardware and installation. A standard single-leaf PVC window without a blind starts at around 340 euros, while one with a motorized blind can be around 600 euros.

Prices according to the profile material

PVC offers the best relationship between thermal performance and price. Kömmerling profiles, manufactured with their own formulation for the Spanish climate, do not need painting, do not corrode with the sea breeze and are 100% recyclable.

Increase according to the type of glass

The shutter box: a worthwhile cost

The blind box is the great forgotten element in many budgets, but on the Costa Blanca, where blinds are essential, it is a key element:

• Standard PVC box: Usually included
• RolaPlus box (hermetic): +50 – 150 EUR over the standard
• Basic motorization: +60 – 100 EUR
• Home automation motorization (LinePlus Könect): +100 – 200 EUR

An airtight box like the RolaPlus o VariNova from Kömmerling eliminates thermal bridges in the shutter area, which in many homes is where the most energy is lost.

Other factors that influence the price

• Size of the opening: Larger windows = more profile and more glass
• Type of opening: Tilt and turn costs more than simple hinged
• Number of leaves: Two leaves cost more than one
• Security hardware: +50 – 100 EUR for RC2
• Special finishes: Wood imitation foils or RAL colors
• Installation difficulty: Difficult access, heights, additional work

How much do you save by changing windows?

According to IDAE, efficient windows can reduce the energy bill between a 25% and a 40%. In an average home in the Marina Alta, this can mean savings of 300-600 euros per year in air conditioning, which means that the investment pays for itself in 5-8 years.

In addition, there are tax deductions and renovation plans that can reduce the cost of the investment. Consult us and we will inform you of the aid available in the Valencian Community.
