We diagnose the actual water source before we quote anything — no guessing, no upsell, just a plan sized to your basement.
We've seen enough Edison, NJ 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.
We're bonded and insured for both residential and light commercial basement work across Edison, NJ.
Most inspection requests get a same-day or next-day appointment, not a two-week wait.
You get one written number before drilling starts, covering drain tile, sump basin, and discharge line.
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 Edison, NJ leak points, and we seal it as part of every interior system.
We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.
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.
You'll see drain tile footage, sump specs, and labor broken out separately, not one vague lump-sum number.
Most residential basement jobs finish in one to three days, and we test the sump pump under load before we leave.
