Why Choose Us

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

A lot of Grandville, MI 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

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 Grandville, MI'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 Grandville, MI Exterior Waterproofing Work

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

Exterior

Foundation Excavation & Membrane Installation

This is the most comprehensive Grandville, MI waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.

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 Grandville, MI 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.

Written Excavation Quote

Excavation, Membrane & Backfill

Excavation, membrane installation, and backfill for a typical residential wall section usually take a few days depending on access and weather.

FAQ

What Grandville, MI 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.

Excavation typically goes down to the footing, which varies by home but is often four to eight feet depending on foundation depth.

Is exterior waterproofing more expensive than interior?▼
