Why Choose Us

Why Wallingford, PA Property Owners Choose SGP Waterproofing for Exterior Waterproofing

Exterior work only pays off if the membrane, footing drain, and grading are all addressed together — fixing one without the others often leaves the underlying pressure problem unresolved. We scope the full picture before recommending excavation.

1

Licensed Excavation & Waterproofing Crews

We call in utility locates before any digging starts, standard on every Wallingford, PA exterior job.

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

Membrane seams are overlapped and sealed to manufacturer spec so the barrier performs as designed for decades, not just years.

What We Do

Comprehensive Exterior Waterproofing Solutions in Wallingford, PA

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

We excavate to the footing, apply a dimpled waterproof membrane directly to the foundation wall, and backfill with proper drainage material.

Exterior

Footing Drain (French Drain) Installation

A perforated footing drain collects groundwater at the base of the foundation and routes it away before it can build pressure against the wall.

Exterior

Exterior Grading Correction

We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.

Exterior

Window Well Excavation & Drainage

We also inspect and reseal the window frame itself while the well is open.

Exterior

Downspout & Gutter Extension

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

Real Exterior Waterproofing Reviews From Wallingford, PA Property Owners

Top rated local Exterior Waterproofing specialists in Wallingford, PA
★★★★★

"Interior fixes hadn't worked for us — turned out the real problem was grading pushing water straight at the foundation. Exterior correction solved it."

— Wallingford Homeowner

★★★★★

"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."

— Wallingford Customer

★★★★★

"Appreciated that they called in utility locates before digging near our gas line."

— Wallingford Homeowner

★★★★★

"Footing drain from the original builder had failed completely. New one actually slopes correctly and moves water like it should."

FAQ

Exterior Waterproofing Questions We Hear Every Week

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?▼

Some disruption is unavoidable near the foundation, but we restore grading and replant where reasonable as part of the scope.

How deep do you need to excavate?▼

We measure your specific foundation during the on-site inspection rather than assuming a standard depth.

Is exterior waterproofing more expensive than interior?▼

Generally yes, since it involves excavation, but it addresses the source of water intrusion rather than managing symptoms after entry.

Can you fix grading without a full exterior membrane project?▼

We'll recommend starting there if the inspection suggests surface water is the primary cause.

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.
