Why Choose Us

Why Pontiac, IL Property Owners Choose SGP Waterproofing for Basement Waterproofing

We've seen enough Pontiac, IL 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.

1

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

No hourly billing and no change orders once your basement floor is already open.

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 Pontiac, IL

Every Pontiac, IL Basement Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.

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

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.

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.
