Initially he was ok but quality of work meant I had to keep asking him to come back to fix the work. Difficult to get him back even though work guaranteed for 12 months.

I wanted a Church Font removing from my garden and this company performed the task with ease. Both of them disposed of the font and cleared the area with no trouble at all. Cannot praise their work ethic enough, polite, pleasant and courteous. Although the font was large they managed to break it up and take away all the remains. Would heartily recommend and they seem to cater for all jobs concerning the garden. Well done lads and thank you.

All electrical work and gas work is all completed by approved and qualified tradesmen. My main trade is joinery but in the 20 years of being in the building game I have gained the experience in each aspect in the building game which has its advantages when project managing a job whilst being on site working.
