Why Choose Us

What Sets Our Exterior Waterproofing Team Apart in Olney, MD

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 Olney, MD's rainy season windows when possible.

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

The Full Scope of Our Olney, MD Exterior Waterproofing Work

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

Soil that slopes toward the foundation instead of away from it is one of the most common Olney, 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

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

How It Works

Our Four-Step Exterior Waterproofing Dispatch Process

01

Call & Exterior Symptom Review

We ask about grading, downspout placement, and where interior water is showing up to narrow down the likely exterior cause.

02

On-Site Excavation Assessment

A technician walks the exterior perimeter, checks grading slope, and identifies where excavation would be needed for a membrane or footing drain fix.

03

Written Excavation Quote

You'll see linear footage, membrane type, and footing drain scope broken out with pricing before any digging starts.

04

Excavation, Membrane & Backfill

We restore grading and any disturbed landscaping as the final step before calling the job complete.

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?▼

We'll walk through both options and their trade-offs so you can make an informed choice.

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.
