Good afternoon. We bought the house already with waterproofing. But soon we started having plumbing problems. And that is our fault. The wife was inattentive and poured waste into the sewer, which clogged our drains. We called the previous owners and they gave us the contacts of the company that repaired their drainage pump and made waterproofing - POM Waterproofing https://pomwaterproofing.ca/exterior-waterproofing/. They also seem to offer plumbing services. Thank you for cleaning everything up so quickly. They also made a diagnosis of the entire plumbing system.
