Now owned by AVH Foundations. Built on the same values.
Basement Worx is the waterproofing and crack repair company of the AVH Foundations family. Alex and the AVH crew took it over, kept everything homeowners trusted it for, and are building on it. Based in Hamilton, serving the same region as AVH Foundations.
How we got here
Basement Worx earned its name on a short list of values: do it right the first time, tell homeowners the truth about what's wrong, and back the work with a No Leak Guarantee. Those values are the reason AVH Foundations took the company over. They aren't being replaced. They're being kept, and held to, on every job.
Under AVH, the waterproofing crew works alongside a structural crew that has been fixing foundations across Hamilton for years. A leak that turns out to be a bowing wall or a sinking footing is handled by the same company, not handed off to a stranger. Every job gets a lead who runs it from the first visit to the last, and the crew doing the work is ours, not a subcontractor's.
Our commitment going forward is simple. The No Leak Guarantee stays on every waterproofing job. Every call and message gets a reply within a business day. Every diagnosis stays honest, even when the honest answer is a smaller job than you expected. And as Basement Worx grows across the region with AVH behind it, that standard is the one thing that doesn't change.
Alex, Owner, AVH Foundations & Basement Worx



Three rules on every job.
They're simple, they're written down, and the whole crew works to them.
Right the first time
Integrity and excellence at the core of every job, so you never deal with the same leak twice.
Honest diagnosis
If it's a leaky pipe and not a foundation problem, we'll tell you. No digging you don't need.
The No Leak Guarantee
We believe in showing, not just telling. If water comes back where we've worked, so do we.
You'll deal with the people doing the work.
Not a call centre, not a subcontractor you've never met. Every job gets a named lead, and you'll have their number.
Alex
Owns and runs Basement Worx as part of AVH Foundations. Quotes the job, stands behind the No Leak Guarantee, and brings the structural crew in when a leak turns out to be more.

The crew
