"Mark Draper, of Huts and Castles, has just completed a total remodel job for me. Not only is his craftsmanship excellent, he is honest, dependable, and always very pleasant. No matter how rough the problems got to be he always had a smile and could repair everything I would recommend Huts and Castles and if I remodel another home I shall use only Mark at Huts and Castles. You cannot go wrong using Huts and Castles.."
