We found damp mouldy drywall in our basement and decided we needed to waterproof. Edgar and his team did the full house from the outside, applying multiple layers of protection, weeping tile system and installing a sump pump. They did an excellent job and I would not hesitate to recommend them. Basement is noticeably better after only a few weeks. Went out of their way to minimise disruption. Thorough site visit and diagnosis of the problem, fair price, good cleanup of what can be a very messy job.
