If your Lexington basement takes on water every spring, you're in good company. Groundwater and snowmelt put real pressure on foundations in this part of the metro, and the fixes are well known.
About basements in Lexington
Lexington is a small, mostly postwar city where ramblers on block foundations are common.
Common problems in postwar and 1960s to 1980s homes
- Block walls with stair-step or horizontal cracks
- Clay drain tile that has silted up or broken
- Water seeping in where the wall meets the floor
- Pumps that have run for decades with no backup
Homes from these years often get new interior drain tile and a new sump pump, with cracked walls sealed or braced. A horizontal crack or a wall that bows inward needs a structural assessment first.
Services in Lexington
- Basement waterproofing: Stop groundwater and seepage before they reach your floor, walls and belongings.
- Sump pump installation and backup: New pumps, second pumps and battery backups for homes where the pump never rests.
- Interior drain tile: Collect groundwater at the footing and carry it to the sump before it reaches the floor.
- Foundation crack repair: Seal cracks that leak and have structural cracks looked at before they spread.
- Basement dehumidifiers and moisture control: Whole-basement dehumidifiers that keep damp, musty air in check all summer.
