What does it cost to close a transom window?
Closing a transom window costs on average between €5 and €150, depending on the method you choose and whether you carry out the task yourself or outsource it. The cheapest option is applying adhesive film yourself for €5 to €15, while having the glass replaced by a professional brings the highest costs.
Overview of costs for closing a transom window per method
| Method type | Execution | Price indication |
|---|---|---|
| Apply transom adhesive film | DIY | €5 - €15 |
| Apply wooden board to transom | DIY | €15 - €25 |
| Apply plasterboard to transom | DIY | €10 - €20 |
| Apply HPL board to transom | DIY | €20 - €40 |
| Replace glass in transom | Outsource job | €100 - €150 |
The table shows that DIY solutions are significantly cheaper than outsourcing the job. The difference lies mainly in the labour costs charged when replacing glass by a professional. With DIY methods, you only pay for the material.
The price for sealing a transom window in DIY projects is calculated per unit and depends on the type of material you choose. Adhesive film is the most accessible, while HPL board (High Pressure Laminate, a wear-resistant board material) is more expensive but offers a higher-quality finish. If you choose to have the transom closed by replacing the glass, you pay for both the new glass and the professional's labour.
All prices include 21% VAT. For DIY options, only material costs are included.

Price-determining factors for closing a transom window
The costs for closing a transom window vary greatly per situation. Various factors influence the total price, from your choice of material to the moment you plan the job. Below you can read what determines the price and how you can save costs.
Chosen method
The method you choose has the greatest influence on costs. Applying adhesive film costs only €5 to €15, while replacing glass by a professional costs €100 to €150. The difference lies in the complexity of the work and the required skills.
DIY or outsource
If you close the transom window yourself, you only pay material costs. When hiring a professional, labour costs are added. For glass replacement, the labour time is longer because the old glass must be removed and the new glass placed accurately.
Material type
The choice of board material influences the price. Plasterboards cost €10 to €20, wooden boards €15 to €25, and HPL boards €20 to €40. HPL is more expensive but provides a more professional and wear-resistant result.
Urgency versus planned work
Urgent repairs cost more than planned jobs. The professional must adjust their schedule and possibly move other work, resulting in higher labour costs. Plan your work ahead to avoid extra costs.
Timing of execution
Work on weekends is more expensive than during the week. Professionals often charge a surcharge for work outside office hours because this falls in their own time.
Complexity of the task
Applying adhesive film is a simple task that takes little time. Replacing glass or applying board material requires more craftsmanship and time, which translates into higher costs. With glass replacement, the old glass must be carefully removed without damaging the door or frame.
Region
In large cities, rates for professionals are often higher than in rural areas. This is due to higher business costs and travel times. The difference can amount to dozens of pounds for the same job.
Preparation and accessibility
If the door and transom are freely accessible, the professional can get straight to work. If furniture must first be moved or if the transom is difficult to reach, this costs extra time and therefore more money.
Material quality
Cheap material seems attractive but can show wear faster. Qualitatively better material is more durable and saves costs in the long run because you do not have to replace it again.
Removal of old material
When replacing glass, the old glass often has to be disposed of. Some professionals charge a small surcharge for this, especially if it involves large pieces of glass that must be specially disposed of.
Local professional versus travel distance
A local professional charges less or no travel time. For professionals further away, extra costs are added for the time they are on the road.
Guarantee and aftercare
Professionals who offer a guarantee on their work often indirectly include this in their rate. This does provide certainty that any problems will be resolved free of charge.

- For the complete removal of a transom window and replacing the frame, costs are on request and depend on the specific situation
How does the professional proceed when closing a transom window?
Closing a transom window follows a series of fixed steps where the old glass is replaced by new material.
- Remove glazing beads: The professional removes the glazing beads on the sides of the glass pane with a flat screwdriver.
- Remove glass pane: The glass pane is gently pressed down, compressing the springs. The top glazing bead snaps loose and the glass pane is tilted forward at an angle and removed.
- Measuring: The length, width, and thickness of the glass pane are measured for the replacement material. These measurements are crucial for an accurate fit.
- Place new material: The bottom glazing bead is slid onto the new material (glass, wood, plaster, or HPL). The material is placed back into the frame at an angle while the springs are pressed.
- Finishing: Once the material is vertical, the left and right glazing beads are screwed back into place. The task takes an average of 30 minutes to 1 hour.
How can you save on closing a transom window?
There are several ways to lower the costs for closing a transom window without compromising on quality.
- Choose the right method: Applying adhesive film costs only €5 to €15 and is ideal if you only want to block light without permanent adjustments.
- Do it yourself if possible: Simple tasks such as applying film or board material can often be done yourself, saving labour costs and only paying for material.
- Plan ahead: Do not book on the weekend or as an urgent job, as you will pay surcharges. Weekday planned work is always cheaper.
- Combine jobs: Do you have multiple transom windows or other small tasks? Perform these at the same time for more efficiency and lower total labour costs.
- 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 reasons to close a transom window
People choose to close a transom window for various reasons, from practical objections to aesthetic preferences.
Too much light
A transom window allows unwanted daylight through, which can be particularly disruptive in a bedroom or home office. The extra light can disturb your sleep or affect the readability of computer screens. By closing the transom, you can decide for yourself how much light enters.
Privacy
The transom window offers too little privacy, especially from neighbours or public spaces. Passers-by can easily look in, which gives an unpleasant feeling. Covering the transom window increases your privacy without needing curtains or other solutions.
Modernisation
A ceiling-high door without a transom window gives a more modern look. Many current living styles feature sleek, minimalist doors without transoms. The cost of closing it is limited compared to the visual improvement it provides.
