Why Choose Us

Why Maple Shade, NJ Property Owners Choose SGP Waterproofing for Exterior Waterproofing

A lot of Maple Shade, NJ exterior waterproofing failures trace back to a footing drain that was installed without proper slope, which means it never actually moved water the way it was supposed to. We verify slope during installation, not just at design.

1

Licensed Excavation & Waterproofing Crews

Exterior work involves excavation near the foundation, and every crew member is trained and insured for that specific scope.

2

Local Equipment Staging

Excavation equipment and membrane materials are staged locally so an exterior project doesn't wait on out-of-town logistics.

3

Flat-Rate Excavation Pricing

Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.

4

Dimpled Membrane & Footing Drain Systems

We install dimpled membrane rated for below-grade use, paired with a footing drain that ties into your existing or new drainage system.

What We Do

The Full Scope of Our Maple Shade, NJ Exterior Waterproofing Work

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

Exterior

Foundation Excavation & Membrane Installation

This is the most comprehensive Maple Shade, NJ waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.

Exterior

Footing Drain (French Drain) Installation

We slope footing drains correctly during installation, since a flat or reverse-sloped drain simply won't move water.

Exterior

Exterior Grading Correction

Soil that slopes toward the foundation instead of away from it is one of the most common Maple Shade, NJ water intrusion causes, and it's often the cheapest fix on this list.

Exterior

Window Well Excavation & Drainage

Window wells collecting water get excavated, fitted with a gravel bed, and tied into the exterior drain system so they stop acting as a funnel toward the foundation.

Exterior

Downspout & Gutter Extension

This is often bundled with grading correction since the two issues usually show up together.

FAQ

What Maple Shade, NJ Customers Ask Us Most About Exterior Waterproofing

What's the difference between interior and exterior waterproofing?

Interior systems manage water after it enters; exterior systems stop water from reaching the wall in the first place, which is more invasive but often more permanent.

Will excavation damage my landscaping?

We discuss landscaping impact during the estimate so there are no surprises.

How deep do you need to excavate?

Excavation typically goes down to the footing, which varies by home but is often four to eight feet depending on foundation depth.

Is exterior waterproofing more expensive than interior?

We'll walk through both options and their trade-offs so you can make an informed choice.

Can you fix grading without a full exterior membrane project?

Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Maple Shade, NJ water intrusion issues on their own.

How long does exterior waterproofing take?

A typical residential wall section with membrane and footing drain work takes a few days depending on access and weather conditions.
