I’ve had this discussion a few times recently, and thought it worth raising here. In my search for a house builder a year or so ago I had a lot of expats bemoaning the sub-standard work of Thais and saying I really needed to pay the premium that falang builders charge to get quality. However, despite these warnings of dire outcomes, I found a young Thai builder and liked the quality of his previous work and his attitude toward building standards. To cut to the chase - in my area (Doi Saket, near Chiang Mai) there are a number of houses being built, and 3 that I know of well. Mine (Thai builder) and two others (falang builders). We moved into our Thai built house a month ago - it took 6 months from start to finish. We have only the most minor of gripes, and got a very good job at a good price - with quality inclusions and great attention to detail. Meanwhile falang house no. 1 that started in the same week as us, and is of a similar size and construction, still hasn’t got a roof on after 6 months, has had numerous delays, cost blow-outs and many other problems. Watching the procession of workers there, I must say I prefer my builder, who has mostly permanent staff rather than a host of subbies and day labourers. Falang house no.2 is even worse. The builder seems to have been totally incompetent. An engineer who inspected it recently recommended tearing it all down, as the work was so sub-standard as to be dangerous. The owner now has a court action in process to recover money paid to the builder, and has taken over supervising the repair & renovation of the building using local workers he has found. So, disregard the myths about inferior Thai builders. There are of course bad Thai builders, as there are of course good falang builders - and all builders are limited by the technology, training levels and materials available here. Due diligence is the name of the game, and don’t fall for the myths.
