What can I say - excellent in all respects. Definitely deserves the 5 stars. Actually deserves 6 stars. Very pleasant to deal with. Kept appointments. Explained what the issue was and how he proposed to address it in words I understood. Gave me a worst case estimate and (fortunately) the job was simpler. Had great equipment - ground penetrating radar and video. Efficient and effective. If (God forbid) we have a blocked drain again, we will call Pat immediately. Recommend him to your friends - I will be.
