What our Clients Say

We could not have wished for a better team to work on the adaptations to our home. Not only was their work of top quality, but their consideration for our family was second to none. They kept the site tidy, kept us up-to-date and kept talking to us, always obviously keen to get things just right for us. Adapting a home for a family member with disabilities could have been a very stressful process, but we were in a great pair of hands with BS Knapp and it was just great.
