Why Choose Us

Why Lawnside, NJ 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 Lawnside, NJ 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

Landscaping restoration is included in the scope, not billed as a separate surprise line item.

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

What Our Exterior Waterproofing Service Actually Covers

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

Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.

Real Exterior Waterproofing Reviews From Lawnside, NJ Property Owners

Top rated local Exterior Waterproofing specialists in Lawnside, NJ
★★★★★

"Membrane and footing drain install took three days but the wall that used to weep every storm has been bone dry since."

— Lawnside Homeowner

★★★★★

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

— Lawnside Customer

★★★★★

"Window well kept flooding every storm. They excavated, added drainage, and resealed the window frame while they were at it."

— Lawnside Homeowner

★★★★★

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

FAQ

What Lawnside, 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?▼

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?▼

Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Lawnside, 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.
