Water damage is one of the most destructive and costly problems a property owner can face. At Cordon Construction LLC, we provide comprehensive waterproofing and repair services designed to protect your home or business from moisture intrusion, leaks, and long-term structural damage.
Our waterproofing solutions cover everything from basement and foundation waterproofing to exterior wall sealing and drainage system installation. We use proven techniques and high-quality waterproofing materials to create a lasting barrier against water penetration — keeping your property dry, safe, and structurally sound year-round.

Our waterproofing work comes with a satisfaction guarantee for your peace of mind.
Our waterproofing and repair process starts with a thorough inspection of your property to identify all existing and potential water entry points. We then develop a customized waterproofing plan that addresses your specific vulnerabilities — whether it’s a leaking basement, a cracked foundation, or poor exterior drainage. Our team executes the solution using proven methods and high-grade materials, ensuring every treated surface is fully sealed and protected. We follow up with a final inspection to confirm the integrity of all waterproofing work before project completion.
Signs include visible moisture, damp walls, musty odors, or visible cracks in your foundation walls.
Most residential waterproofing projects are completed within 2–5 days depending on the size and severity of the issue.
Absolutely — we specialize in waterproofing solutions for both new construction and older properties throughout Maryland.
We first repair all existing damage and then apply waterproofing solutions to prevent future issues completely.
