Excellent both in the prep work as well as in the final product. Very professional and good PR as well. Highly recommended for all. Another plus point, monitoring personally done by the owner throughout the work in progress on a timely basis. Keep up the excellent work 3DI!

3DI did a renovation on my balcony and backyard - replaced the balcony railing with a 6-panel glass wall with doors; tiled the yard turning it into a porch; and put up a tiled roof over the porch.
One word to describe the workmanship: EXCELLENT. (So much so that the neighbours asked for 3DI's number.)
If you are serious about quality, 3DI is the one for you.
