Top Dog found the source of our leak when others couldn’t and fixed it - quickly and on budget. Professional and punctual, I highly recommend them!

Rod was professional and patient, sharing his knowledge and answering all my questions. His team quickly found out why our basement was flooding with every rain and fixed it for us - fast! I can’t say enough good things about Top Dog!

After getting a huge water bill, it was obvious there was a leak, but not obvious where. Rod came out right away and found the issue on day one. I wish I could give them 6 stars!

Rod and his team were on time (actually early!), professional, and most importantly did excellent work. They quickly found the problem, fixed it and left my house as clean as when they arrived.

Top Dog found the leaks in the roof of our historic home and repaired it fast. They treated my property with respect and cleaned up, leaving it free of debris. I highly recommend hiring them!

Soon after buying our new house we realized that we had a significant slab leak. The pricing was in line and the work was beyond our expectations. We were so happy with Top Dog that we hired them to finish our basement!
