We hired The Professional Installer to underpin, waterproof and finish our basement. Tony, the owner was a good salesman and made many promises most of which he failed to deliver on. Tony was basically absent from the project shortly after it started leaving most of the job up to his foreman Patrick who perhaps understood how to dig but not how to properly manage things.
The bottom line: the waterproofing was not done properly and Tony was not willing to correct his mistake. We had to call in another company to fix the job done by Tony and his crew. I would not recommend the Professional Installer whatsoever.
