A standard interior drainage and sump system installs in 1 to 2 days. Crack injection is a few hours. Crawl space encapsulation runs 1 to 3 days. Exterior excavation runs 3 to 7 days depending on lot access. Same- or next-week scheduling is typical in Greater Cincinnati.
More detail
A typical Cincinnati interior drainage day runs crew arrival around 7:30 AM, saw-cutting the perimeter slab and breaking out concrete through the morning, digging the trench to the footer and setting the drain tile in gravel by early afternoon, installing the sump basin and pump and the wall drainage membrane, then pouring the slab back flush late in the day; a full-perimeter system or one requiring finished-wall removal extends into a second day. Single-crack injection is a half-day visit, a few hours of port-setting, injection, and cure. Crawl space encapsulation runs 1 to 3 days depending on square footage, whether standing water has to be addressed first, and whether old fiberglass batting and debris need removal and disposal. Exterior excavation is the long job at 3 to 7 days, governed almost entirely by lot access, the depth of the footer, weather (you cannot leave an open excavation through a multi-day Cincinnati soaker), and how much landscaping or hardscape has to come out and go back. The slab-pour-back on an interior system needs above-freezing cure conditions, so a hard cold snap can shift the finish step. Booking 1 to 3 weeks ahead is the comfortable lead time during the wet spring peak; emergency calls for an actively flooding basement get prioritized within Cincinnati-area capacity. Free on-site assessments produce a written, fixed-price quote good for 30 days, and warranty terms are confirmed in writing before any work begins.
