What does it cost to install window frames?
Installing window frames costs an average of between €2,000 and €7,150 per project, including labour and VAT. The exact price depends mainly on the dimensions of your windows and the type of frame you choose. Smaller frames are logically more affordable than larger projects where several windows are replaced at the same time.
Costs of window frame installation per dimension
Dimensions in cm | Price indication |
|---|---|
160 x 130 | €2,000 - €4,000 |
300 x 150 | €2,500 - €5,000 |
340 x 130 | €4,550 - €7,150 |
This table shows what you can expect for different frame sizes. The costs for plastic window frames are usually at the lower end of these ranges, as plastic is generally more affordable than wood or aluminium. For larger dimensions or multiple frames installed at once, the costs can naturally increase.
The price of plastic window frames is attractive due to lower material and maintenance costs, but dimensions remain the biggest determining factor. If you want to estimate the costs of replacing window frames and windows, it is wise to first know the exact sizes of your windows. The affiliated professionals charge per project and take the specific situation at your home into account.
Please note: The prices mentioned include 21% VAT and labour. These are indicative prices based on previously completed jobs via Zoofy.
Costs of window frames per material type
The choice of wood, aluminium, or plastic influences not only the purchase price but also the maintenance costs and lifespan of your window frames. The costs for plastic window frames are often the most attractive due to the combination of price, maintenance, and insulation value. Wooden frames have a characteristic appearance but require maintenance every 5-7 years and last 30-40 years. Aluminium frames are strong and modern, lasting 40-50 years with minimal maintenance, but insulate less well. Plastic window frames are low-maintenance, last 25-35 years without painting, and are available in various colours.
Material | Maintenance | Lifespan | Insulation value |
|---|---|---|---|
Wood | Paint every 5-7 years | 30-40 years | Good |
Aluminium | Minimal | 40-50 years | Moderate |
Plastic | Low-maintenance | 25-35 years | Good |
Price-determining factors for installing window frames
The total price for installing window frames is determined by several factors. Below you can read which aspects influence the costs and why one job turns out more expensive than another.
Dimensions and surface area
Dimensions strongly determine the price of your window frames. Larger frames require more material and longer labour time. A frame of 160 x 130 cm is installed faster than a large frame of 340 x 130 cm, which directly affects the price.
Material type and profile choice
Wood is more expensive to purchase than plastic due to higher raw material prices and processing time. A block profile gives a classic look but is solid. A slim profile provides more light in modern homes but requires more precise production work, which increases the price.
Type of glazing
HR++ glass consists of two layers and is standard in many homes. HR+++ glass has three layers and insulates better, but increases the purchase price due to the extra material and higher weight. Better insulating glass does lower the energy bill.
Window type and operation
A fixed window is the simplest and most economical because no pivot points or hinges are needed. A tilt-and-turn window has a more complicated construction with more hardware and adjustment mechanisms, causing the price to rise. A bottom-hung window is often used in high places and requires special hanging constructions.
Standard sizes versus customization
Standard sizes are more economical because they are produced in larger series. Deviating sizes or special finishes increase costs because machines must be precisely adjusted and production time increases.
Height and accessibility
Window frames on the first or second floor are harder to install than on the ground floor. The professional may need scaffolding, and for flats, a crane is sometimes even needed to bring material up. This increases the labour time and rental costs for equipment.
New construction versus renovation
With new construction, old window frames do not need to be removed and the walls are still clean. With renovation, extra activities such as checking for moisture damage, adjusting masonry, and repairing plasterwork occur, which increases the costs.
Removing old window frames
In older homes, window frames are often less securely attached than in new builds, but they can also be grown into the masonry. Time-consuming removal without damage to walls or rebates increases labour time and thus the total price.
Urgency and planning
Urgent jobs are more expensive than planned work because the professional must adjust their schedule and possibly postpone other jobs. If you plan your window frames in time, you can save on labour costs.
Weekend or evening hours
Work at the weekend costs more than during the week due to weekend surcharges. Evening jobs after 18:00 also often involve extra costs.
Regional price differences
In large cities, the price for plastic window frames is often higher than in rural areas. This is due to higher parking costs, longer travel times, and generally higher operational costs for professionals in urban areas.
Preparation of the workplace
Ensure the workplace is clear and accessible. Remove curtains, window decorations, and move furniture away from the windows. This saves the professional time and prevents you from paying extra hours for preparatory work.
Addressing problems in time
Addressing small problems such as drafts or condensation in time is more economical than repairing major damage such as wood rot. If you wait too long, the costs for replacing window frames can rise significantly due to extra repair work on frames, plasterwork, or even insulation.
Extra costs and surcharges when installing window frames
Extra costs are situation-dependent. At Zoofy, you do not pay call-out charges.
Installing ventilation: Installing ventilation in the frames costs an average of €40 to €60 per metre and ensures better air circulation and less chance of mould.
Locks and hinges: A lock with the 'secure living' police quality mark costs approximately €80, while a simpler lock is available from €10.
Plastering and finishing: When replacing window frames, damage can occur to plasterwork or tiles around the window, meaning repair work by a plasterer is invoiced separately.
Disposal of old window frames: Ask in advance whether the disposal of old window frames is included in the costs or calculated separately.
Urgency surcharge: A surcharge often applies to urgent jobs because the professional must adjust their planning.
Weekend surcharge: Work at the weekend is more expensive than during the week due to weekend surcharges.
How does the professional work when installing window frames?
Installing window frames follows a fixed set of steps that ensure a solid end result.
Intake and measurement: The professional assesses the existing situation and measures accurately. During renovation, they check for moisture damage or wood rot in the existing frames and cavity wall.
Advice and ordering: Based on the measurement, the professional advises on material (wood, aluminium, or plastic), profile type, and glazing. Then the frames are ordered from the factory. Costs are definitively determined in this phase.
Production and delivery: Standard frames have a shorter delivery time than custom-made ones. Count on several weeks of production time before the frames are delivered.
Removing old window frames: During renovation, the professional first carefully removes the old frames and checks the cavity wall for moisture problems or insulation defects.
Installation and finishing: The new frames are placed level, firmly secured, and all seams are sealed for optimal insulation. The customer checks with the professional whether windows function smoothly. Installing one window frame takes a few hours.
How can you save on the installation of window frames?
There are several ways to lower the costs for window frames without compromising on quality.
Address problems in time: Solving small problems like drafts or condensation immediately prevents wood rot and larger damage. This saves significantly on costs in the long run.
Prepare the workplace: Remove curtains and window decorations yourself, move furniture away, and protect valuable items from dust. This saves the professional time and keeps labour time low.
Plan during the week: Do not book the job at the weekend or as an urgent task. Planning during the week saves on surcharges.
Replace multiple frames at once: When replacing several frames at once, you benefit from economies of scale and a more favourable total price.
Book via Zoofy: You get a fixed rate in advance, without call-out charges and without surprises. You only pay after the job is completed.
Common signs that window frames need replacing
Problems with window frames often arise gradually due to wear, moisture, or age.
Drafts despite draft strips
If you still experience drafts despite draft strips, the frames may be deformed or worn. This leads to energy loss and an uncomfortable indoor climate. Replacing the frames solves this structurally.
Condensation between double glazing
Moisture between the glass layers indicates a broken seal. The glass or frame must be replaced to prevent moisture problems and mould formation.
Difficult-to-close windows
Windows that no longer open or close smoothly indicate subsided or warped frames. This affects not only the ease of use but also the burglary resistance of your home.
Wood rot or moisture damage
Visible rot spots or soft spots in wooden frames require quick replacement to prevent further damage to walls and insulation. Waiting increases costs significantly.
High energy bill
Poorly insulating frames let heat escape. New frames with HR++ or HR+++ glass lower heating costs and improve living comfort immediately.
