Interior drain tile, sump basins, and vapor barrier wall systems installed by technicians who've done this hundreds of times in Lansing, MI basements.

We've seen enough Lansing, MI basements to know that a wet spot in one corner rarely tells the whole story. Before we recommend drain tile or a sump upgrade, we trace the water back to where it's actually entering, not just where you noticed it.
Every technician carries full state licensing and liability coverage before they ever step into your basement.
Most inspection requests get a same-day or next-day appointment, not a two-week wait.
No hourly billing and no change orders once your basement floor is already open.
Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.

We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.
We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.
Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.
The cove joint where the floor meets the foundation wall is one of the most common Lansing, MI leak points, and we seal it as part of every interior system.
A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.
Window wells that hold water after a storm are a direct pressure point against the glass and frame — we add gravel beds and drain lines tied into the main system.

You describe what you're seeing — a wet spot, a musty smell, standing water — and we get a rough read on urgency before dispatching anyone.
A technician walks the basement with a moisture meter, checking walls, floor, and cove joints to trace the water back to its actual source.
We explain the reasoning behind the recommended system so you know exactly what you're paying for and why.
You'll get warranty paperwork and a walkthrough of how the system works so you know what to expect going forward.
