So far, very disappointed with Megasealed.
With the initial work being completed in 2009, leaks started to reoccur early 2012. I called Megasealed, in order to have a warranty consultant attend my address and assess the issue. An appointment was made for approximately two weeks later.
Having taken the morning off work, the warranty consultant did not show. A call to Megasealed indicated that no such booking was recorded on their systems.
When the warranty consultant finally did show (two weeks later), consultant was quick to dismiss Megasealed's work being the cause of the problem; this is despite me pointing out cracks and gaps in the Megasealed product . The Megasealed consultant indicated that the leak was a plumbing issue. I called a plumber, and, to Megasealed's credit - there was a small leak coming from behind the tap spindle. This was promptly addressed. Of note is that the leak would only occur when the shower was actually running.
Still convinced that the Megasealed product was defective, I taped up the drain to the shower, and filled it with water from a bucket - negating the need to use any of the shower taps. Sure enough, despite being properly taped off, the shower hob was empty the next morning; and the leak even more prominent than before. The fact that the shower hob had longer exposure to water (as opposed to a quick 5 minute shower), meant that clearly the Megasealed product was not performing to the standard its manufacturers claim it should.
I left a voice message for the warranty consultant, however my phone call wasn't returned. Due to a busy schedule, I have not been able to follow up this problem until now, and I am finding the leak is getting worse.
I understand that problems can occur, which is what a warranty/guarantee is for. However, Megasealed do not deliver on their guarantees, and as such I would exercise caution in using them for shower repairs.
