Kitchen Fitting- 1 May 2019
From the initial meeting to the completion of the job both Sam and josh were fantastic, punctual, polite and more than happy to discuss any issues. The work was completed to a very high standard and I would have no hesitation in recommending them. I have already asked them to do another job for me and certainly will in the future.
