Replacing uPVC window frames in Rotterdam
Replacing window frames in a Rotterdam home, commercial property or larger construction project may require close coordination. Access may be limited, the building may have several users, or other trades may be working at the same time. ACS Montage removes and installs uPVC window frames and agrees in advance how the work will fit the schedule.

The installation
A workable approach for every type of location
Rotterdam has a wide range of buildings and working conditions. Every project still starts with the same essentials: accurate measurements, an accessible work area and clear agreements about the work. Before starting, we discuss which window frames will be replaced, the route for bringing in materials and who the on-site contact will be. In an occupied building, we take daily routines into account; on a construction site, we follow the agreed logistics and safety rules.
After removing the old window frame, we check the exposed opening. We position, secure and align the uPVC frame, then test the windows and doors to ensure they operate properly. We also check that the surrounding connections match the agreed finish. If the conditions on site differ from what could be seen beforehand, we report this promptly to the client or site manager rather than making assumptions.
Before work starts
Agreements that help prevent delays
Loading and unloading
On busy streets or construction sites, we agree in advance where materials and tools can be unloaded safely and conveniently.
Access to rooms
Make sure the agreed rooms or work areas are accessible on time. This prevents delays and last-minute changes to the day's schedule.
Site coordination
On larger projects, we follow the agreed work sequence and coordinate any overlapping work with the site manager or contractor.
