Why Choose Us

Why Hempstead, NY 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

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

2

Local Equipment Staging

Weather-dependent scheduling means we plan exterior jobs around Hempstead, NY's rainy season windows when possible.

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

Comprehensive Exterior Waterproofing Solutions in Hempstead, NY

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 Hempstead, NY 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 Hempstead, NY 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.

Customer Reviews

What Hempstead, NY Customers Say About Our Exterior Waterproofing Work

Top rated local Exterior Waterproofing specialists in Hempstead, NY
★★★★★

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

— Hempstead Homeowner

★★★★★

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

— Hempstead Customer

★★★★★

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

— Hempstead Homeowner

★★★★★

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

— Hempstead Customer

FAQ

What Hempstead, NY Customers Ask Us Most About Exterior Waterproofing

What's the difference between interior and exterior waterproofing?▼

We'll recommend the right approach based on what the inspection actually finds.

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?▼

Larger projects or difficult access points can extend the timeline, which we'll outline in the written quote.
