How We Get the Job Done

When Garden City homes face basement flooding or moisture issues, Diamond steps in with proven methods and years of experience. Whether it’s interior or exterior waterproofing, we attack the problem at its root so you can enjoy a dry, safe, and worry-free basement.

French Drains

French drains are designed to move water away from your home’s foundation, keeping your basement dry and safe from flooding over time.

Sump Pump Systems

Sump pumps jump into action the moment water is detected, removing it before it has a chance to pool or cause damage, especially during downpours or snowmelt.

Basement Crack Repair in Garden City

We seal up foundation cracks and waterproof both inside and out, preventing leaks, mold, and the need for costly repairs down the line.

Grated Channel Drains

These systems collect surface water and divert it away from your home. Perfect for areas with frequent rainfall, they help reduce puddles and prevent foundation seepage.

Exterior Membrane Protection

An exterior membrane wraps your foundation in waterproof armor, blocking moisture before it can reach your basement. It’s a heavy-duty solution for homes that need maximum protection.

Foundation Grading

We reshape the ground around your home to slope water away from the foundation. This simple solution can prevent major flooding and structural damage.

Window Well Drains

Window well drainage systems stop water from pooling around basement windows, protecting one of the most vulnerable parts of your home from leaks.
