      Shane was great. Original visit was for plumbing inspection per contract. He was upfront and honest with a few diagnosis he pointed out. We knew eventually we would start having some issues. Shane scheduled us for next day. Worked alone never missing a beat. I would request Shane if I should ever need anything again.
