Why Choose Us

What Sets Our Exterior Waterproofing Team Apart in Towson, MD

A lot of Towson, 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.

What We Do

Comprehensive Exterior Waterproofing Solutions in Towson, MD

Every Towson, MD Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.

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

Soil that slopes toward the foundation instead of away from it is one of the most common Towson, MD water intrusion causes, and it's often the cheapest fix on this list.

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.

FAQ

What Towson, MD 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?

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?

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