  1. Tim Schoenfeld (via Google) -

    Here you not only get an offer, but also a precise, individually planned terrace according to all your wishes when you first contact us. Nothing was left unaddressed. The concept BETTERWOOD convinced me, as does my finished terrace. Many thanks again to the team and their performance.

  2. Marcus Bonin (via Google) -

    Very good advice; individual appointment coordination and on time, goods (terrace wood) really good and everything as expected. Gladly again!
