After previous positive experiences with Ster Kozijn, we had new garage doors installed. The installers even arrived fifteen minutes earlier than expected after the long drive from Oldenzaal. Two very pleasant and courteous men. Based on the drawings, they knew exactly what they would encounter and did a fantastic job. They also cleaned up everything and explained how the locks worked. That help was necessary, because we're used to a master key that could have been used to enter anyone's home 80 years ago. But it worked, and just to be sure, I tried ten more times. Works perfectly. Thank you very much.

The gentlemen at Ster Kozijn did a great and professional job on our 1930s house. Beautiful window frames that are almost identical in design to the originals shown on the building plans. Even the neighbors had a smile on their faces when the fitters arrived cheerfully. Even minor problems were addressed and fixed immediately.

Because STER Kozijn had installed window frames in our previous home to our complete satisfaction (15 years ago), we had them installed in our current home as well. They also renovated the dormer window and cladding the facade, bargeboards, and gutters. Everything was done perfectly by the skilled installers.

Last week, Sterkozijn replaced the window frames throughout the house. The work was done very professionally by a very professional team.
