Your service. Our craftsmanship.
Your request
What would you like to use again reliably?
Choose the appropriate situation. We will take over your selection in the service request.

Clings or slips
The wing scrapes against the frame or can only be moved with force.

Air leakage at the window
Have the seal, pressure, and connection tested together.

Handle or locking mechanism
The handle jams, turns erratically, or does not lock reliably.

Multiple windows
Maintenance and repair for several rooms or an entire building.
Repair with discretion
First understand. Then systematically restore it.

A window is more than its handle.
Hardware, wing position and sealing affect each other. Therefore, we look at the entire window. Only then can it be assessed whether a setting is sufficient, whether a wear part can be replaced, or whether further work is necessary. A photo helps with preparation; the diagnosis is made on the existing element.
Our services
What we check for your system.
Set up and check
We control operation, locking, and wing position and adjust the setting to match the existing system.
Restoring fittings
The handle, gearbox, scissors and other components are assessed based on their condition and the available replacement part solution.
Appraisal of seals
We are checking whether a seal is worn out or the cause of the draught is elsewhere.
Plan maintenance
Moving parts, attachments and wear are checked. Proper maintenance depends on the system in place.
Insights into our work
From the detail to the usable system again.
Records from the PLANIGRAPH service show damage, expert work, and specific installation situations.



Costs and decision
A suitable solution begins with an honest assessment.
Not every problem requires the replacement of the entire system. Condition, workload, access, and spare parts determine which repair is advisable. We will discuss the next steps and the planned work with you. A preliminary photo assessment does not replace an on-site examination.
Simply ask for an offer
This is how we prepare your service.
1 · Send situation
Describe the problem. Photos of the complete system, details and easily identifiable markings are helpful; a photo is not a prerequisite for a request.
2 · Grouping together
We are examining which details are still missing and how the deployment can be prepared.
3 · Schedule to be agreed upon
The scope, access, and urgency will be taken into account. A date request will be personally coordinated.
4 · Perform properly
The agreed work will be carried out on-site. The results and any further requirements will be discussed in a transparent manner.
Companies and municipalities
A contact person for your entire fleet of equipment.
Multiple premises, buildings, or locations? We support governments, companies, and public contracting authorities with repair and planned maintenance. Please provide us with the number, location, and usage of the affected facilities. This way, access, contact points, and procedures can be prepared together.

Repair & Maintenance
Maintenance maintains functionality and can prevent consequential damage.
As with mechanically-stressed components, regular inspection is worthwhile. We check function, wear and adjustment and only recommend the work that is technically necessary.
- Checking, cleaning and lubricating fittings
- Adjust the windows and make them operable
- Suitable seals and wear parts are replaced
- Check safety features and consider retrofit options
Well prepared
Your questions before the service appointment.
Do I have to install a new window right away?
Not automatically. The condition, repair costs and availability of replacement parts are crucial. We show which repairs are worthwhile for the existing window.
Do you repair windows from other brands as well?
Yes, our service is brand-agnostic. Whether a specific repair is possible is determined by the system in question.
Which photos help you?
A general view showing the visible problem area and the existing hardware markings. Please do not remove anything and do not move the blocked wing for the photo.
Can I report multiple windows together?
Yes. Please specify the number, rooms and the respective problems. For larger quantities, we can coordinate a joint pick-up and maintenance.
How much does a window repair cost?
This depends on the nature of the defect, accessibility, workload, and the parts required. These points are clarified before the agreed work is carried out.
