What does it cost to replace window frames?

The cost of replacing window frames varies significantly by material. uPVC frames cost €350–900 per frame including installation. Wooden frames €450–1,100 per frame. Aluminium frames €600–1,500 per frame. For an average house (8–12 frames) you pay €4,000 to €12,000 including HR++ glazing.

Which is better: uPVC or wooden frames?

uPVC frames are maintenance-free, cheaper, and thermally efficient. Wooden frames have a warmer appearance and are easier to repair but require regular painting (every 5–8 years). For a modern home without heritage status, uPVC generally offers the best value for money.

What is the difference between HR++ and triple glazing?

HR++ glass (double) has a U-value of approximately 1.1 W/m²K and is the standard for frame replacement. Triple glazing (HR+++) has a U-value of 0.6–0.7 W/m²K — better insulating but approximately 25–40% more expensive. Triple glazing is worthwhile for new builds or renovations where the facade is also well insulated.

Do I need a permit to replace window frames?

When replacing frames in the same location with the same material, you generally do not need a permit. If you enlarge the frames, change the facade, or the property has heritage status, an environmental permit is usually required.

How long do new window frames last?

uPVC frames last 30–50 years without major maintenance. Wooden frames can last just as long if painted regularly. Aluminium frames are virtually unlimited in lifespan and rust-proof.

Are there subsidies for frames with HR++ glass?

Yes. Through the ISDE subsidy you can receive a contribution for HR++ glazing as part of an energy-saving package. The subsidy is approximately €25–50 per m² of glass. Apply via rvo.nl after completion.

Smart savings

How to keep costs down

Replace only the glass if the frame itself is still in good condition — this easily saves €200–400 per frame.
Have all frames replaced at once: contractors charge less per frame for larger jobs.
Combine with the ISDE subsidy: receive approximately €25–50 per m² of glass back via rvo.nl.
Choose uPVC if you want the best value for money — thermally just as good as aluminium at a lower price.
Schedule replacement in autumn or winter — contractors are less busy and prices may be slightly lower.
