One of the DMV's Most Experienced Underpinning Teams
With over 170 completed basement lowering and underpinning projects, Go Pro Construction brings proven structural expertise to one of the most specialized services in residential construction: basement lowering, underpinning, and crawl-space conversion.
Over 170+ Successful Underpinning Jobs Since 2010
Basement lowering and underpinning is not a service most general contractors offer — and for good reason. It requires advanced structural knowledge, precise phased sequencing, and strict adherence to engineering and safety standards at every step. Done wrong, the consequences are severe. Done right, it unlocks space that most homeowners never thought possible.
Go Pro Construction has completed more than 170 basement lowering and underpinning projects across the DMV, including the structural underpinning of a 124-year-old foundation and the creation of a full basement apartment from a 2-foot crawl space in an occupied DC rowhouse. That depth of experience across foundation types, jurisdictions, and project conditions is what separates a capable team from a qualified one.
What Basement Lowering & Underpinning Makes Possible
Whether your basement is too low to finish, your crawl space is too shallow to use, or you’re planning a high-end upgrade like a golf simulator, basement lowering creates the headroom you need without moving or rebuilding above.
- Basement floor lowering: Excavation and underpinning performed to increase ceiling height and create code-compliant living space within existing structures.
- Foundation underpinning: Structural reinforcement of existing footings executed in carefully controlled phases, with structural integrity verified at every stage.
- Crawl-space-to-basement conversions: Transformation of shallow crawl spaces into full-height basements, including projects in occupied rowhomes, attached homes, and structurally sensitive properties.

Basement Lowering & Underpinning Frequently Asked Questions
Underpinning is the process of extending or reinforcing an existing foundation to allow the basement floor to be lowered. It requires precise phased excavation which includes removing and pouring concrete sections in a carefully controlled sequence so the structure above is never left unsupported. It demands advanced structural knowledge, strict engineering oversight, and experience reading how a specific foundation will respond at each phase. Very few general contractors in the DMV are equipped to do it correctly.
More than 170 across the DMV region, making Go Pro one of the most experienced underpinning teams in the area. Projects have ranged from standard ceiling-height expansions to the structural underpinning of a 124-year-old foundation and a full basement conversion from a 2-foot crawl space in an occupied DC rowhouse.
The average project runs approximately 180 days. That timeline is driven by engineering requirements, mandatory inspection intervals between phases, and concrete curing periods that cannot be shortened. We are transparent about this from the first conversation — this is not work that should be rushed, and we don’t rush it.
In most cases, yes. Go Pro has completed underpinning projects in occupied homes, including rowhouses where homeowners continued living on the floors above. Site conditions, scope, and local requirements all factor into whether in-home occupancy is feasible — we assess this during the pre-construction phase and plan accordingly.
Yes. We have converted crawl spaces as shallow as 2 feet into fully usable basement apartments, including in occupied DC rowhouses. The process involves careful excavation, underpinning, new drainage and moisture systems, and a finished concrete floor — all engineered and permitted through Go Pro.
Several high-value upgrades integrate naturally into the new floor system: insulated floating slabs for thermal performance, radiant heated floors via in-slab water pipes, sub-floor French drains, and sump-pump systems for long-term moisture control. These are most cost-effective when incorporated during construction rather than added later.
Yes. Engineering, permit applications, inspection scheduling, and coordination with local authorities are all managed in-house by Go Pro — across Maryland, DC, and Virginia. Given the structural nature of this work, permitting is extensive, and our familiarity with the process across all three jurisdictions is a meaningful advantage.
