Carpentry- 17 Oct 2025
Nico did a fantastic job. The new wardrobe doors look amazing and fit perfectly after adjusting to fit the older door frames which had settled and moved slightly out of alignment over the years. Better than the original ones. The bedroom doors were replaced and fitted to open to the correct side of the rooms. The broken stair was expertly cut and fitted and matched perfectly to the rest of the stariway. Very solid and completely squeek free. Built to last a very long time. Nico is very reliable, dependable and highly skilled. I highly recommend him for any carpentry work needed.
