This beautiful classic colonial home had aged very gracefully, but had a few water filtration issues thanks to some old plumbing stacks in the roof that the squirrels had helped along. We removed all the damaged lead plumbing stacks and, In its place, we installed premium metal flashing with neoprene seals. The end result was completely waterproof and left the squirrels with years of work ahead of them to get the stacks back in that shape again.
