Why Choose Us

Four Reasons Our Exterior Waterproofing Clients Don't Call Anyone Else

A lot of London, OH 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

We call in utility locates before any digging starts, standard on every London, OH 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

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

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

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

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

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

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

FAQ

Frequently Asked Questions 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.
