How this works
Same process,every service.
- 01
Inspect
Someone walks the site and finds where the problem is actually coming from — not just where it shows up.
- 02
Diagnose
We name the root cause and explain it in plain language, including what happens if you do nothing.
- 03
Written scope
A specific price for a specific fix, in writing, before anyone picks up a tool. No sight-unseen numbers.
- 04
Do the work
Licensed crew executes exactly what was scoped. If something changes behind the wall, you get a call first.
Questions
Straight answers.
- How long does waterproofing take?
- Most interior drain tile jobs finish in 1–3 days depending on the length of wall affected. The exact timeline is in the written scope before we start.
- Will you need to dig up my yard?
- No — interior drain tile is installed from inside the basement, along the footing, under the slab. Nothing outside gets disturbed.
- What's the difference between interior and exterior waterproofing?
- Exterior seals the outside of the foundation before water reaches the wall; interior manages water that's already gotten in and gives it a controlled path out. We'll tell you honestly which one your situation needs — sometimes it's both.
