Had MTC install a shower last year. Price was good, shower was installed in a reasonable timeframe.
After complaints of a leak from the downstairs neighbours, I discovered a year later that a hidden seam was left uncaulked, resulting in significant water damage to the bathroom, and the apartment below.
At this point I found out that MTC's "warranty" is worth only the paper it's written on. MTC readily answers the phone, service is friendly, and they happily promise to get back to me, schedule an appointment, and show up for scheduled appointments. Delivering on those promises however, is something else. It took months to get someone to even have a look, and 6 months later, still no one has shown up to start repair work.
