"I forgot to do this review but am glad I did because I am two years out having waterproofing services by this company. The drain and sump pump recommended by Robert Ellis is absolutely worth it. I no longer am anxious about weather forecasts because of the work done. Robert evaluated my home, gave me options and soft recommendations then allowed me space to make the best long term decision. Completely satisfied and would recommend."

"My sump pump was starting to fail. Shane was able to confirm the problem and replace the sump pump. From initial call to replacement was one day. Excellent service! After work was complete, everything was cleaned up. Overall, professional service and efficient billing/invoicing/etc. I highly recommend DB. This is the second time I have used DB and both times have been great."
