French Drains & Two New Sump Pumps
“The basement in our 1960's home had been leaking water for years and we finally made the decision to get it fixed for good. We're really happy we went with Down Under Waterproofing. They explained that a new french drain system with two sump pumps would stop our water concerns in the basement. Once a date was set, Walt and his team were on time and completed the job in the 4 day estimate that was given and our basement has been dry ever since. Down Under gave us the best price and did exceptional work. They've also been easy to contact after the job was complete for any questions we've had. I would highly recommend!”
French Drain + Sump PumpsRetaining Wall Repair Before a Home Sale
“Wow, I could not have been happier with the work. I was very concerned as we were selling the house and it was discovered that a retaining wall behind my property needed repair. This was a really big job and I did not want to lose my buyers. Walter could not have been more accommodating. They came in on time, finished on time and at the cost quoted. I was not even around to ensure that the work was being done, but it was. My buyer was extremely happy with the outcome and the sale of the house went through without a hitch.”
Retaining Wall RepairCracked Basement Wall Waterproofing
“The work that Down Under did was by far the best work I ever seen. I had one neighbor come by to look at the work as it was being done and she said it was a great job. Max and the crew did what I considered to be above and beyond to make sure the water will not enter into the basement... Each day Max would explain what had been done and what they would do the next day. They arrived each day on time and if they were going to be late I was informed. Also the basement wall was sealed in a way no water will come through.”

“You can't do better than Down Under for your masonry needs! We were selling our home and the steps to the back door were falling apart and needed a speedy repair. Max came over and handled the work easily and professionally. He was quick, friendly, fairly priced and the steps look perfect. I would absolutely use them again. Do not hesitate to call them for masonry work!”
