How much does it cost to replace windows?
The costs for replacing window frames average €550 per window, including labour and materials. The price varies between €550 and €850 per window, depending on the window type, dimensions, and chosen material. Material costs average €400 per window, while labour costs are €50 per hour.
Overview of window replacement costs
Description | Price |
|---|---|
Average cost of labour and materials per window | €550 |
Price range per window | €550 - €850 |
Material costs per window | €400 |
Replacement window (product) | €200 - €1,000 |
Labour costs | €50 per hour |
These prices provide a realistic idea of what to expect when replacing windows. The wide range in product prices is because uPVC windows are cheaper than wooden or aluminium variants. The size of the window also plays a significant role in the total costs.
When you install new windows, the costs include removing the old frames, installing the new windows with glass, and finishing. For those specifically choosing to replace glass in existing frames, a different price structure applies. The price for installing double glazing in existing wooden windows is usually lower because the frame is retained.
All mentioned prices include 21% VAT and labour.
Costs of replacing windows per type
The costs for replacing frames depend heavily on the chosen material and the type of window. Aluminium and uPVC (vinyl) are generally the most affordable options, while wooden frames and special window types such as bay windows and egress basement windows are significantly more expensive.

Price-determining factors for replacing windows
The costs for replacing frames vary greatly per situation. What is a standard job for one home may require more time, materials, or expertise for another property.
Frame material type
The chosen material affects both the purchase price and the lifespan. Aluminium and uPVC frames are usually cheaper, while wooden frames cost more due to the level of processing and maintenance. Fibreglass and composite materials fall in between in terms of price but often offer a longer lifespan.
Glass type and insulation value
Energy-efficient windows with double or triple glazing cost more than single glass. Low-E coatings and gas fills such as argon or krypton further increase the price but lower your energy bills. The investment often pays for itself through lower heating costs.
U-value of the window
The U-value indicates how well a window insulates. Old windows often have values of 3.0 W/m²K or higher, while modern HR++ windows are below 1.0 W/m²K. The lower the U-value, the better the insulation and the higher the material costs.
Window dimensions
Larger windows are disproportionately more expensive. The extra weight requires sturdier construction, longer installation time, and sometimes even extra help. A large window 2 metres wide costs more than two smaller windows 1 metre wide.
New construction versus renovation
Renovation windows are placed in existing frames and are often faster and cheaper to install. With new construction windows, you replace the entire frame, which requires more work but results in a completely new system.
Customisation and non-standard sizes
Standard sizes are more economical than custom work. Older properties or monumental homes often have non-standard sizes, which entails longer production times and higher costs.
Window type and complexity
Bay windows, skylights, and windows on higher floors require more expertise and time. For windows on upper floors, the professional charges an average of €50 extra per window for an additional hour of work. Tilt-and-turn windows are easier to install than sliding doors or fixed glass sections.
Accessibility and preparation
If the workplace is easily accessible and free of obstacles, the professional works faster. Remove curtains and furniture near the windows before the job begins.
Urgency versus planning
Urgent jobs are more expensive because the professional has to adjust their schedule. Plan your job in advance to save costs.
Weekend and evening work
Work during the weekend or in the evening costs more due to higher rates. Choose weekdays during the day if possible.
Regional differences
In large cities, costs are often higher than in rural areas due to more expensive labour costs and parking issues. These price differences can be up to 15 per cent.
Condition of existing frames
If there is wood rot or water damage, the professional must first repair or strengthen the frame before the new window can be installed. Addressing small problems like drafts or condensation early is more cost-effective than repairing major damage later.
Platform and transparency
With Zoofy, you know what you pay in advance, without call-out charges or surprises afterwards. You work with local professionals who can be on-site quickly.
Additional costs and surcharges
Extra costs are situation-dependent. At Zoofy, you do not pay call-out charges, but certain circumstances may incur a surcharge.
Urgency surcharge: For urgent tasks, a surcharge often applies as the professional must adjust their schedule.
Weekend surcharge: Work during the weekend is more expensive than during the week.
Windows on higher floors: For installing new windows on upper floors, a surcharge of €50 per window applies for an extra hour of work.
Removal and disposal: The removal and disposal of old frames and glass is often not included in the quote. Verify this beforehand.
How does the professional work when replacing windows?
The task follows a set sequence of preparation, disassembly, and installation.
Inventory and measurement: The professional assesses the situation and takes exact measurements of the existing openings.
Disassembly of the old window: The old window and, if necessary, the frame are carefully removed, preventing damage to the walls.
Preparing the opening: The opening is cleaned and checked for damage. Repairs are carried out to ensure a solid base.
Installing the new window: The new window is placed level and square in the opening to ensure it closes and turns properly.
Sealing and insulating: The joints are sealed for an airtight finish. Good sealant joints are essential to prevent drafts, moisture, and heat loss.
Finishing and inspection: The finish is checked and the window is tested for proper operation.
Installation time varies from 1 to 6 hours per window, depending on complexity.
How can you save on replacing windows?
Address small problems early: Drafts or condensation indicate poor insulation. Repair this before wood rot or larger damage occurs.
Clear the workspace: Remove curtains and furniture near the windows so the professional can start immediately.
Plan smartly: Do not book on the weekend or as an urgent task, as higher rates apply. Plan preferably in spring or autumn.
Choose standard sizes: Custom work requires longer production times and higher costs. Standard sizes are more affordable.
Replace only the glass: When frames are still in good condition, consider only glass replacement.
Inquire about subsidies: The ISDE subsidy supports energy-efficient home improvements. Check the conditions like the minimum U-value.
Book via Zoofy: You get a fixed rate in advance, without call-out charges and without surprises.
Common problems with old windows
Old windows can cause various problems that affect comfort, energy costs, and the state of your home.
Condensation between double panes
Permanent condensation between double panes points to a failed seal of the glass. The insulation layer is compromised, allowing moisture to enter and significantly reducing the insulation value.
Drafts with closed windows
Drafts with closed windows indicate poor gap sealing, worn weather strips, or warped frames. This results in heat loss and an unpleasant cold airflow.
High energy costs due to outdated windows
Outdated windows with high U-values let a lot of heat escape. Installing new windows with modern insulation values often pays for itself through lower heating costs.

A reliable professional ensures correct installation, allowing you to benefit from your new windows for years.
Certifications: Check if the professional has relevant certifications like KOMO or VCA.
