We recently had some water damage. It wasn't a massive job which made it hard to find someone to help, but Mike and Jono were keen and happy to do the work! They did a great job and organised the whole job for us! Definitely recommend Reinholt for any job small or large!

Johno recently installed your new shower. He was on time, kept to the quote was really friendly, tidy and great to deal with. We would definitely use Johno and his team on any other jobs we may have in the future. We really like the name is so easy to remember.
