Basement Waterproofing in the Lehigh Valley, PA

Interior French drains, sump pump systems and drainage that dry a basement from the inside — so you can use the space, finish it, and stop dreading the forecast.

Basement waterproofing

Dry From The Inside Out

Most basement water comes in at the cove — the joint where the floor meets the wall — or through floor cracks, pushed up by groundwater pressure. Paints and sealers on the wall don’t stop that. An interior French drain does: it collects the water below your floor, before it ever reaches the surface, and sends it to a sump pump that moves it out of the house. It’s the proven fix, it’s done entirely from inside, and it’s the same crew that finishes basements — so the work is planned with the finished space in mind.

  • Interior French drain systems — perimeter channel below the slab
  • Sump pump installation & replacement, battery backup options
  • Drainage where water actually enters — the floor/wall joint
  • Concrete cut, hauled out & re-poured — we handle the whole job
  • Honest assessment first — gutters, downspouts & grading checked before we sell you a system
  • The right first step before any basement finish

Signs it’s time

What Water Is Telling You

  • Puddles or damp spots after rain
  • Water marks along the base of the walls
  • Musty smell that never quite leaves
  • White, chalky residue (efflorescence) on the concrete
  • Peeling paint or bubbling on basement walls
  • A sump pump that runs constantly — or died quietly

Any one of these means water is getting in. Left alone, it doesn’t get better on its own — and it rules out ever finishing the space until it’s handled.

Our process

How An Interior French Drain Works

Assess & Find The Water

We walk the basement, find where water’s entering, and check the simple stuff outside first — gutters, downspouts, grading. If the fix is out there, we’ll tell you.

Cut & Trench

A channel is saw-cut along the inside perimeter, concrete hauled out, and a trench dug below the slab at the footing.

Drain & Sump

Perforated drain pipe goes in on a gravel bed, pitched to a sealed sump basin. The pump is installed and the discharge routed safely out of the house.

Close & Restore

Fresh concrete re-poured flush with your floor. What’s left is a dry basement — ready to use as-is, or to finish.

What to expect

Straight Answers, Before We Start

Cutting concrete is loud, dusty work for a day — we protect the rest of the house, haul our own debris out, and keep you posted at every stage. Most interior drain systems are in and closed up within a few days, depending on how much of the perimeter we’re running. You get the scope, the price, and the schedule in writing before anyone picks up a saw.

After it’s dry

Then The Basement Becomes Living Space

A dry basement is the starting point for everything else — storage that doesn’t smell, a workshop, or a full finish like this one. Planning to finish yours? Waterproofing comes first; see what a finished basement looks like.

FAQ

Waterproofing Questions

Exterior systems mean excavating around your foundation — decks, porches and landscaping in the way, at several times the cost. An interior French drain manages the water that reaches the foundation from inside, which solves the problem for most homes at a fraction of the disruption. And if your water is really a surface problem — short downspouts, bad grading — we’ll tell you that first instead of selling you a system you don’t need.
It’s priced by the job, not off a chart: linear feet of drain, whether a sump pump is needed, and how the concrete has to be cut and restored all move the number. We walk your basement, measure, and give you an exact price in writing for free — so you’re deciding on a real number.
We recommend it. The storms that push the most water at your foundation are the same ones that knock out power — and a pump that can’t run is no pump at all. A battery backup keeps the system working through an outage.
Yes — that’s exactly the order to do it in. Dry first, then finish. Finishing over a moisture problem just hides it until it ruins the new work. Once your system is in, we can finish the space too — see our basement finishing page.
