Trustworthy, Efficient, and Skilled Drainage Solutions
“Smart Contracting is hands down the best drainage contractor we’ve worked with. From start to finish, they were incredibly prompt, arriving on time every day and staying on schedule. Not once did we experience any hidden fees or unexpected charges – they kept every aspect of the invoicing transparent and clear.
Their reliability and professionalism made the entire process stress-free. Smart Contracting was always available to address any questions we had, and the quality of their work was outstanding. We won’t hesitate to use their services again and highly recommend them to anyone in need of trustworthy, efficient, and skilled drainage solutions.”

Excellent Job!
“We had our Quake damaged drains replaced. This is a very inconvenient thing to do when you only have a single driveway for property access. They kept the inconvenience down to a minimum and ensured the site was safe at the end of every day. Other properties in the area had theirs done by other contractors around the same time and the level of care and overnight site safety we received became very obvious when compared with these other contractors. I would definitely use them again. They did an excellent job and I'm glad to have had the opportunity to compare their work to other options around the area to see I made the correct choice.”
— Andrew McMillan
Friendly, Prompt, Professional and Super Informative
“Mike and his team were exceptional! They were friendly, prompt, professional and super informative. They let us know about things that would benefit us, that no one else had bothered to bring to our attention. I would highly recommend this crew - they were awesome!”
