Why Choose Us

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

A lot of Riverdale, MD 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 Riverdale, MD 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

Comprehensive Exterior Waterproofing Solutions in Riverdale, MD

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 Riverdale, MD 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 Riverdale, MD 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

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?▼

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 Riverdale, MD 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.
