Professional Drainage Solutions on Long Island

Standing water, soggy lawns, and flooded basements are more than a nuisance — they’re a threat to your property’s foundation, landscape, and value. Complete Landscaping & Masonry designs and installs comprehensive drainage systems that solve water problems permanently, not temporarily.

Long Island’s flat terrain, high water tables, and clay-heavy soils create drainage challenges that generic solutions can’t fix. Our team conducts thorough site assessments to identify water sources, flow patterns, and soil permeability before designing a system that addresses the root cause — not just the symptoms.

We install French drains, dry wells, channel drains, catch basins, sump pump discharge lines, and regrading solutions for residential, commercial, and HOA properties throughout Nassau and Suffolk Counties. Every system is designed to handle Long Island’s heaviest rainfall events.

Why Choose Us

Why Our Drainage Systems Work

Root Cause Analysis

We don't guess — we assess water sources, soil permeability, and flow patterns to design a system that solves the actual problem.

Engineered for Long Island

Our systems account for Long Island's high water tables, clay soils, and flat terrain — conditions that require specialized drainage approaches.

Foundation Protection

Proper drainage protects your home's foundation from hydrostatic pressure, preventing costly structural damage and basement flooding.

Multiple System Types

French drains, dry wells, channel drains, catch basins, and regrading — we use the right combination for your specific conditions.

How It Works

Our Drainage Process

1

Site Assessment

We evaluate water sources, soil conditions, grade, and existing drainage. We may conduct a percolation test to measure soil absorption rates.

2

System Design

Based on our assessment, we design a drainage system using the right combination of French drains, dry wells, catch basins, and grading.

3

Excavation

Trenches are dug to proper depth and slope, with careful attention to existing utilities, irrigation lines, and landscape features.

4

Installation

Perforated pipe, filter fabric, and gravel are installed per design specifications. Dry wells and catch basins are set at calculated locations.

5

Restoration

Trenches are backfilled, sod is replaced, and the landscape is restored. We test the system with water to verify proper flow before completion.

Common Questions

Drainage FAQs

How much does a French drain cost on Long Island?

French drain installations typically cost $30-$60 per linear foot on Long Island, depending on depth, soil conditions, and accessibility. A typical residential French drain system runs $3,000-$8,000.

What's the difference between a French drain and a dry well?

A French drain collects and redirects water along a trench. A dry well is a collection point where water percolates into the surrounding soil. Most effective systems use both — French drains to collect water and dry wells to disperse it.

Can you fix a wet basement from the outside?

In many cases, yes. Exterior French drains, regrading, and downspout extensions can redirect water away from your foundation without interior waterproofing. We assess whether an exterior solution will solve your specific problem.

Do I need a permit for drainage work?

Most residential drainage work doesn't require a permit, but connecting to municipal storm drains or making significant grade changes may require approval. We handle any necessary permits.

How long does drainage installation take?

Most residential drainage projects take 2-5 days. Complex systems with multiple dry wells and extensive trenching may take up to 2 weeks.
