This company is a total scam! We were noticing a bad smell in our basement so we called them out for an inspection. They basically ended up telling us we needed a $20,000 system where they would dig a ditch around the entire house, drill holes in the wall, etc. This seemed crazy to me because our home is not that old, has never flooded, and has no leaks. So we called for second opinion and turns out we just had a dry catch in pipe in basement.... they poured water down pipe and haven't had smell since. So glad we didn't spend 20K on something we clearly didn't even need!! I don't know how these salesmen sleep at night trying to rip people off. Do not work with this untrustworthy company!
