Schrijver Damp Control has proven such a success for us. We first used the company when we bought a house in 2007 and had such good results, that when we moved to this new address we know we wanted them to repeat the magic! The crew who came to do the installation were friendly, informative, helpful and hardworking. Also quite importantly they cleaned the site when they were finished, taking the rubble away and it all clean and tidy. We recently had the follow-up recheck results – one year since installation which shows a significant drop in the damp levels and which will continue to keep the walls damp free!
