We decided to use Dima Plumbing to install a replacement toilet (that we bought) based on HomeStars recommendations, and we were not disappointed. John provided a competitive estimate prior to booking, showed up on time, was courteous throughout, and took care in installing, even adjusting a pipe escutcheon (hole cover) that we didn't realize beforehand would interfere with the new toilet's larger bowl. He was also upfront when asking us to approve an additional item (cutoff valve replacement, which we suspected might be necessary) rather than surprising us with it on the invoice.
As of this review a few days after installation, the new toilet seems to be working well, and we wouldn't have any difficulty recommending John for future work.
