“We have had Wisecracks do a couple of jobs for us and I can’t say enough good things about them and their employees. Wisecracks did a great job with minimum disruption to the household. The workers preforming the work were knowledgeable, pleasant and explained each step they needed to complete. I will recommend Wisecracks to family and friends which is the best review I could give, thanks Wisecracks for a job well done!”

“ have had 4 different foundation cracks fixed by wisecracks now. Every time it has been a great experience. A year later the cracks are still totally sealed and show no signs of leaking or breaking down, and Wisecracks offer a lifetime guarantee if they do! Friendly people who do a good, careful job and leave the space clean! Thanks to Dan especially. Great work.”

“Regarding the job you completed last summer, just to let you know there wasn’t a drop of infiltration through the cracks, which remain perfectly tight. Although I wouldn’t wish to require your services again, I wouldn’t hesitate to call if I did, or recommend you. Thanks for your expert work.”
Russell Dmytriw, P.Geo.
“Great company to deal with, lots of knowledge in the basement waterproofing business. They take time to explain to you a solution to your problem. I already have recommended them and will continue in the future.”
