Hannegan Construction is a locally owned and operated residential whole-home remodeling company serving our neighbors in DC and Northern Virginia.
If you’ve noticed cracks in your walls, uneven floors, or doors that won’t close quite right, it could be a sign that your foundation needs attention. Hannegan Construction offers practical foundation repair services for homeowners across Washington, DC and Northern Virginia. We keep things simple, explain what we see, and help you decide what fix makes the most sense for your home and budget.
Not every crack means trouble—but some do. Common signs that may point to a foundation issue include:
Cracks in drywall or exterior brick
Floors that feel sloped or unlevel
Gaps around windows or door frames
Water seepage in the basement or crawl space
Foundation walls that bow or shift over time
If you see one or more of these, it’s worth having someone take a look. We’ll walk the property with you and let you know what we find—no pressure, no upsell.
We specialize in helping homeowners address foundation problems quickly, affordably, and with minimal disruption. We’re not a corporate franchise and don’t use scare tactics to push expensive solutions. Instead, we focus on the most effective repair for your situation: patching cracks, stabilizing footings, or underpinning sections that have shifted.
We commonly repair:
Poured concrete and block foundations
Crawl space and basement foundations
Slab settling issues
Water-damaged or deteriorating foundation walls
We can advise if more extensive work—like underpinning—is needed to prevent future movement.
Older homes, shifting soils, heavy rains, and dense urban construction all contribute to foundation issues in this area. We’re based in Reston and work throughout DC, so we’re familiar with the conditions that affect homes here. Whether you’re in a 100-year-old row home or a 1990s colonial, we’ve likely seen something similar before.
Call us if you suspect a foundation problem—or just want peace of mind. We’ll take a look, explain what we see, and let you know your options.
