Why Choose Us

Why Leonardtown, MD Property Owners Choose SGP Waterproofing for Basement Waterproofing

Basement waterproofing mistakes usually come down to one thing: fixing the symptom instead of the source. A contractor who paints over a wet wall without checking cove joint condition or exterior grading is setting you up for the same call again in a year or two.

Licensed & Insured Crews

Every technician carries full state licensing and liability coverage before they ever step into your basement.

2

Same-Day Local Dispatch

Most inspection requests get a same-day or next-day appointment, not a two-week wait.

3

Flat-Rate Pricing, No Surprises

You get one written number before drilling starts, covering drain tile, sump basin, and discharge line.

4

Moisture-Mapping Equipment

We use pin-type moisture meters and a flashlight-and-crowbar inspection to trace water back to its real entry point.

What We Do

Comprehensive Basement Waterproofing Solutions in Leonardtown, MD

We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.

Basement

Interior Drain Tile

We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.

Basement

Sump Pump & Basin Installation

Battery backup is available for any sump system, so a power outage during a storm doesn't undo the whole fix.

Basement

Wall Crack & Cove Joint Sealing

Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.

Basement

Vapor Barrier Wall Membrane

We install membrane on masonry walls before any insulation or framing goes up, so moisture never gets a chance to reach finished materials.

Basement

Window Well Drainage

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.
