"The estimate was for thousands of dollars less than other Waterproofers. There was one company who was less - he refused to do the job as the basement was small, and the home older so the basement will never be a finished basement. Down Under was easy to arrange financing through Chase. The worker arrived as scheduled. There was a problem with my sewer pipe and the company worked about my need to schedule a plumber and worked about his schedule. Then they returned to set up the washer and dryer after the cement cured. They job was completed as quickly as possible considering my sewer pipe situation."

" Walt was a great guy. He came in and worked with us on the windows we wanted replaced. He also gave us good counsel when we were thinking about not doing the bathroom area. When the team finished he made sure they came back to reconnect the washer and dryer for me and stop up an open pipe to prevent water from sneaking in. The job took down our finished basement but there is no more odor when it rains! I check everytime."

I contracted Down Under Waterproofing to reinforce my foundation using carbon fiber. I researched, did my homework, and contacted two manufacturers, one being Fortress Stabilization. They sent Down Under Waterproofing's information. Walter represented the company, came to our house, gave us an estimate, had an engineer write up drawings, picked up the permit, and had the whole basement done in two days. The turn around time was two weeks between initial consultation and completion. It relieved us greatly because this was a real estate transaction.
