Questions

Asked before every job.

Straight answers. If yours isn't here, call and ask. You'll get someone who does this work, not a script.

Interior or exterior waterproofing, which do I need?
Exterior waterproofing stops water before it reaches the wall and is the most permanent fix. Interior systems manage water that gets in and are often the practical choice for finished basements or tight lots. We recommend the one that actually fits your house, not the most expensive one.
How fast can you come out?
Call or text a photo and we'll usually get eyes on it within a couple of business days, sooner for active leaks.
Will my basement really stay dry?
That's what the No Leak Guarantee is for. If water comes back through an area we've waterproofed, we come back.
Do I need to tear out my finished walls?
Not always. Crack injection is done from inside with minimal disruption, and exterior work happens outside. When we do need access, we tell you exactly where and why before we start.
What does crack repair cost?
Most single crack injections are a same-day job. We quote in writing after seeing it.
