Yes, Trinity is quite good in terms of fixing workmanship issue. I bought my unit sub-sale but lucky was still under warranty. The water pipe in the master bedroom toilet leaked badly and water came out of the wall.

The developer hacked the wall and fixed the leak in about 2 weeks. Took 2 days of hacking to find the leak causing multiple holes in the wall. However, they managed to cement and fit back the tiles nicely. You can't differentiate before and after hacking. Good job!
