Can anyone recommend a builder to make a doorway and install a door in an outside wall?

I can recommend K. Song. He has done various items of building work for me over many years, most recently last month. He lives in Sansai. Please PM me for his telephone number.

We used a good builder for our extension and roof. PM me if you want his details, he doesn't speak much English so it helps if you have a Thai person who can talk to him.
