A steam-engine water stop that gave the town its name
The Columbia, Newberry and Laurens Railroad — locally nicknamed the “Crooked, Noisy, and Late” — built its line through the area in February 1890 and set up a water stop for refueling steam locomotives; the settlement, officially incorporated December 24, 1890, took its name by combining the surnames of railroad officials C.J. Iredell and H.C. Moseley.
From a fueling stop to a lakeside water table
Irmo's growth accelerated after the Dreher Shoals Dam created Lake Murray between 1927 and 1930, and much of the town now sits close enough to the lake that the water table can run higher than in towns farther from the shoreline. A waterproofing assessment here should account for that lake-driven groundwater level, not just surface storm runoff.

Details that help an Irmo estimate
Note how long water has been an issue, whether it's tied to storms or constant, the home's rough age, any past repairs, and access around the foundation. Confirm any provider's licensing and insurance directly.
Confirm lake-area drainage and permit rules
Because so much of Irmo sits near Lake Murray, drainage and grading work close to the shoreline can carry additional review. Check current Town of Irmo and Lexington/Richland county requirements before digging.
