Had two amazing experiences with DrainWorks and Chris Léger and can't recommend them enough. Super clean work, very knowledgeable and incredibly courteous and professional.
The first time, we had a bathroom sink that rusted out to the point that the entire cold water handle broke off in my hand. Couldn't fix it myself so I called DrainWorks. DrainWorks sent Chris Léger and he did an amazingly thorough and expert job of installing a completely new tap/faucet combo. He suggested I change out the drain/trap combo leading into wall as well as he could see that it was starting to rust out but I opted to not do it to save cost. Bad idea, because exactly as Chris predicted it might, the drain/trap combo broke about 3 months later, creating a giant leak.
So, we had DrainWorks/Chris come back a second time to replace the drain/trap and all the piping going to the wall. He did an equally amazing job the second time around and never even said "I told you so" :)
