Hannegan Construction is a locally owned and operated residential whole-home remodeling company serving our neighbors in DC and Northern Virginia.
Whether your home is settling unevenly or you plan to dig deeper, this method helps stabilize your home’s foundation and prevent further movement.
Beam and base underpinning is one of the most reliable ways to reinforce a home’s foundation—especially in older properties or when preparing for structural changes like basement renovations or additions. Hannegan Construction offers beam and base underpinning services to homeowners across Washington, DC, and Northern Virginia who need added support beneath their homes.
Beam and base underpinning involves installing a reinforced concrete beam beneath the existing foundation wall. The beam helps spread the load more evenly, while a series of concrete bases (or “pads”) are added underneath to support the beam. This combination creates a new, stronger foundation system underneath your home—without needing to rebuild the original structure.
It’s a method often used when:
The existing foundation is shallow or deteriorating
The soil has shifted or eroded over time
A home addition or basement excavation is planned
Structural engineers recommend extra load-bearing support
This type of underpinning is common in DC rowhomes, aging properties, and homes with visible signs of structural stress. If you’re seeing wall cracks, sloping floors, or struggling with doors and windows that don’t open or close properly, beam and base underpinning might be part of the solution.
We also recommend it when doing deeper basement digs, especially when converting a crawl space into usable living space or creating a walkout.
At Hannegan Construction, we don’t overcomplicate things. Our team focuses on practical, straightforward solutions that match your project and budget. We work efficiently, often on short notice, and aim to keep things moving without unnecessary delays or red tape. We can also coordinate with structural engineers if needed to make sure everything’s done safely and to code.
If you think your home may need structural support or you’re planning a renovation that involves foundation work, reach out to us. We’re based in Reston and serve all of Northern Virginia and Washington, DC. We’ll take a look, explain your options, and give you an honest recommendation.
