This basement was dark, old, and had flooded several times with rainwater and/or sewage. We hauled away many loads of ruined possessions, wood paneling and drywall.
We then fixed the 8-foot crack in the basement wall using the Simpson Strong-Tie CRACK-PAC Epoxy Injection Kit. (That’s a separate story involving excavation of the front yard.)
We removed all the floor tiles, cleaned the concrete walls and floor, sub-contracted the services of a plumber and an electrician, strapped the water heater to the walls, replaced the clothes dryer vent, and added new pilasters, a lighting soffit, Cat6 ethernet wiring and coaxial cable, and fresh paint.
The homeowner placed the renovated house on the market and received multiple offers the first day.
