GRIDON the contractor for Expats

GRIDON has always had a natural link with the Expat community in The Netherlands. Not in the least because of being Expat ourselves, but also because the company language is English. This means communication is easy. But we also offer our “Expat service” for novice expats, facilitating them with all our knowledge how to get around and about in renovation and housing in The Netherlands. Many Expats have been extremely pleased with working with us and have become longstanding relations.

We welcome you to become the next!
