Hannegan Construction is a locally owned and operated residential whole-home remodeling company serving our neighbors in DC and Northern Virginia.
A dry basement is the foundation of a healthy home, and choosing the right basement waterproofing company makes all the difference in long-term protection. Hannegan Construction provides comprehensive basement waterproofing solutions designed to stop leaks, prevent moisture intrusion, and protect your home from the costly damage that water can cause.
Basements are naturally prone to water issues due to below-grade pressure, changing soil conditions, and aging foundation systems. Whether you’re dealing with damp walls, musty odors, visible seepage, or recurring flooding, our team identifies the true source of the problem—not just the symptoms. As an experienced basement waterproofing company, we analyze your home’s grading, drainage, foundation condition, and existing waterproofing measures before recommending a customized solution.
Our services include interior and exterior waterproofing, foundation crack repair, sump pump installation, French drains, vapor barriers, dehumidification, and moisture-resistant insulation. We use proven methods and high-quality materials to ensure your basement stays dry year-round, even during heavy rains or seasonal groundwater changes. Every project is engineered for durability and backed by craftsmanship you can trust.
Moisture issues can affect indoor air quality, cause mold growth, and damage flooring, drywall, and stored items. Addressing these problems early not only protects your home but also enhances your comfort and preserves long-term property value. With Hannegan Construction, you’ll have a dedicated project manager who keeps communication clear and ensures the waterproofing process is efficient and minimally disruptive.
Whether you’re preparing to finish your basement or simply want peace of mind, Hannegan Construction is the basement waterproofing company homeowners rely on for reliable, lasting results. Contact us today for an assessment and see how we can safeguard your home from moisture and water damage.
