Why Choose Us

What Sets Our Exterior Waterproofing Team Apart in Northville, NY

A lot of Northville, NY 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 Northville, NY's rainy season windows when possible.

3

Flat-Rate Excavation Pricing

Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.

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 Northville, NY 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

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

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.

Customer Reviews

Real Exterior Waterproofing Reviews From Northville, NY Property Owners

Top rated local Exterior Waterproofing specialists in Northville, NY
★★★★★

"Interior fixes hadn't worked for us — turned out the real problem was grading pushing water straight at the foundation. Exterior correction solved it."

— Northville Homeowner

★★★★★

"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."

— Northville Customer

★★★★★

"Window well kept flooding every storm. They excavated, added drainage, and resealed the window frame while they were at it."

— Northville Homeowner

★★★★★

"Footing drain from the original builder had failed completely. New one actually slopes correctly and moves water like it should."

— Northville Customer

FAQ

Exterior Waterproofing Questions We Hear Every Week

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?

Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Northville, NY water intrusion issues on their own.

How long does exterior waterproofing take?

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

Our Services in Northville, NY

The site of the village was first settled around 1786, but areas south of the village were settled around 1762. The village was once on high ground between the Sacandaga River and Hunters Creek. When the river was dammed in 1930 to form the Sacandaga Reservoir, now called Great Sacandaga Lake, the river valley became an arm of the lake. The village now lies on a peninsula surrounded by the lake, with three bridges connecting it on the west, east and south. The arm of the Great Sacandaga Lake to the east is known locally as Northville Lake or the "Little Lake".
