• About us


Our company has been based in Alkmaar since 1993 on the industrial estate "De Bevenkoog". What started as a contractor. Since 2000, the company has been taken over by Mike Snijders, who has focused entirely on window frames and sun blinds. The company has been located at Hazenkoog 24d in Alkmaar for more than 25 years. From here all activities are coordinated. From 2000 De Konstruktie works with permanent self-employed people who install the frames and sun blinds with all the peace of our (regular) customers.

All of these products come from suppliers based in the Netherlands and with whom the Constitution has been doing business for years. We serve both private individuals and contractors.
