How much does window frame replacement cost in 2026?
Window frame replacement costs in 2026 are typically between €400 and €1,200 per frame, depending on material, dimensions, and glazing type. The biggest cost drivers are whether you choose wood, PVC, or aluminium, plus HR++ or triple glazing, the frame size, and how many frames are replaced at once. Installation complexity, access to the façade, and finishing details also affect the final budget. For a full terraced house, total project costs generally range from €3,000 to €15,000. Many homeowners replace windows and frames together, which usually lowers the cost per frame. So if you compare quotes for a complete package instead of single units, your average price often becomes more favorable.
Costs by material: wooden, PVC, and aluminium frames
Your material choice strongly affects both appearance and total replacement cost. Wooden frames usually cost €500–€900 per unit and offer a classic look with strong insulation, but they require regular painting. PVC frames are typically €400–€800 per unit and are low maintenance, which is why they are the most common choice. Aluminium frames are usually €700–€1,200 per unit and suit modern homes thanks to slim profiles and high durability. Steel frames are often €800–€1,500 per unit, mainly chosen for an industrial design style. Choosing between PVC and aluminium has a major impact on final project costs, especially when you include long-term maintenance and finishing. In practice, the best option depends on budget, façade style, and desired maintenance level.
What does it cost to replace all window frames in a house?
Whole-house costs depend on the number of frames, chosen material, and installation complexity. For a terraced house with 8–12 frames, typical ranges are €3,500–€10,000 (PVC), €5,000–€12,000 (wood), and €7,000–€15,000 (aluminium). A semi-detached home with 10–15 frames usually falls between €5,000 and €15,000. Detached homes with 15–25 frames can range from €8,000 to €25,000. The more frames you replace in one project, the lower the average price per frame, because installers often offer volume discounts. For example, 10 new PVC frames with HR++ glass generally cost €4,000 to €8,000 including installation.
When to replace old window frames and when to repair?
Replacement is usually the better choice when frames have structural issues. Clear warning signs include wood rot, draughts, cracks, poor closing, and condensation between glass layers. These issues often indicate the frames are at end of life. Minor problems—such as superficial wood rot, worn seals, or slight sticking—can sometimes be repaired cost-effectively. But when damage is widespread, replacing frames is often cheaper in the long run than repeated repairs. In most Dutch municipalities, you can replace frames without a permit if the external appearance does not materially change, but always check local rules first.
What do window frame replacement costs consist of?
Window frame replacement costs are built from several components. Around 40–50% of the total usually goes to the frame material itself. Glazing adds another major part: HR++ or triple glass is often €100–€300 extra per frame. Installation typically costs €150–€400 per frame, depending on size and access. Disposal of old frames usually adds €50–€150 per unit, while finishing work (sealing, painting, trim) often adds €50–€100 per frame. Final costs are mainly influenced by material choice, frame size, and glazing specification. That is why itemized quotes are essential when comparing suppliers.
Subsidies for window frame replacement in 2026
Subsidy can improve the business case when you replace frames and upgrade glazing at the same time. In 2026, homeowners may qualify for ISDE support when installing HR++ or triple glass during frame replacement. The amount depends on glazing type and square meters; triple glass rates can be significantly higher than HR++ rates. Make sure both the frames and glass meet current subsidy requirements and approved product criteria. Some municipalities also offer local incentives, especially when combining multiple insulation measures. Apply through mijn.rvo.nl before work starts to avoid losing eligibility.
How can you save on window frame replacement costs?
To save money, start with project scope and quote quality. Always compare at least three itemized offers, because pricing differences can be significant. Replacing all frames in one go often reduces cost per frame through volume efficiency. Choosing PVC instead of wood or aluminium can lower upfront costs. You can also save by using available subsidies, scheduling work in off-season periods, and discussing whether you can handle disposal tasks yourself. SkilledContractors helps you compare quotes quickly, so you can find the best value for your home and budget.

Can I get a subsidy for window frame replacement?

Do you need a permit to replace window frames?
In most cases, you can replace frames without a permit if the appearance of the home does not materially change. If you change material, color, or layout, a permit may be required. Always verify with your municipality.
When should window frames be replaced?
Window frames are often due for replacement after roughly 30 to 50 years. Warning signs include wood rot, draughts, condensation between panes, cracks, and poor closing windows. Minor issues can be repaired, but structural problems usually justify replacement.
What is the cost difference between PVC and wooden frames?
PVC frames are generally €100 to €200 per unit cheaper than wooden frames. Wooden frames also have higher maintenance costs because they need periodic painting. PVC is lower maintenance and widely chosen in the Netherlands.
Are windows and frames replaced at the same time?
Yes. In most projects, windows and frames are replaced together, with glass installed directly into the new frame. Replacing only glass can be cheaper, but it is less effective when the existing frame is in poor condition.
How can I save on window frame replacement costs?
You can save by replacing multiple frames together, choosing PVC, using available subsidies, and comparing at least three quotes. SkilledContractors makes it easy to find local professionals and compare offers.
