Our biggest advantage to you, the customer, is that the people on-site, in the office, and the directors still have that old-fashioned pride in our work. Our crew are full-time wages staff and we have worked together, in some cases, for over thirty years. To ensure continuity, productivity and the best way of carrying out the job on-site, we also employ younger staff. We value our staff highly and have a very low turnover. This is how we can guarantee consistency in our jobs that other companies can only dream about.
