OUR TESTIMONIALS
As a medium sized building contractor i employ Jason as a Quantity Surveyor to take off and provide bill of quantities for architects and clients on all my projects. All my work tends to be via referrals on high end residential projects in and around Cardiff and the Vale. I find his level of professionalism fits perfect with our business and the added comfort of the services he provides allows me to focus on the building side of life and not worry about the commercial aspects and pricing, valuations and contract disputes.
I’ve worked with Jason on a number commercial and residential projects in South Wales and find his level of service to be very exceptional. He delivers tenders for submission always on time and in a professional manner that reflects well for my companies image. The flexible nature of our working relationship is that i can I can present the services of a professional Quantity Surveyor without the extra pressure of employing a full time QS. Our relationship works perfectly and i will continue to put work his way as i grow as a building contractor.
