Groot in Kozijnen

Groot in Kozijnen – production partner for professional construction

Groot in Kozijnen is not only an installation company but a production partner for construction professionals seeking reliability. From our own production site in Berkhout (West Friesland), we supply PVC window frames, doors, and sliding doors to contractors, dormer manufacturers, and prefab and timber frame builders throughout the Netherlands.

We collaborate with clients who build serially and require fixed dimensions, predictable delivery times, and clear communication. Because we produce in-house, we keep communication direct and speak the same language as the workshop floor. No extra links, no noise, but clarity in planning, coordination, and delivery.

Our clients choose Groot in Kozijnen because they want to continue building without surprises. We engage in the preliminary phase, carefully coordinate details, and consistently deliver as agreed. This way, we form a stable link within the construction process, where continuity and reliability are essential.

Besides our business clients, well-prepared private customers can also order directly from us. Installation is then carried out by the customer themselves or through their own contractor, fully in line with our role as a producer.
