So I had a leak in my shower and my plumber gave me the option which involved putting hole in ceiling below. I came across wingtite and decided I’ll give it a try. I do lots preparation before I start a project and since I had brass drain it was going to be little more difficult. I called the wingtite tech support left a voicemail and got call back in minutes. Greg was awesome and very informative. Gave me tips and confidence that is can be done. It’s actually not super easy with brass drain removal but I got it done. It’s was not too bad. Few hours but I took my time. I gave it 24 hours for silicone to dry and just got out of the shower and no leaks. I’m extremely pleased. Would definitely recommend.
