Interior vs exterior waterproofing: which does your home need?

Contractors in Trumbull County usually propose one of two approaches, and the choice changes cost, disruption, and results.

Interior systems include perimeter drain channels along the footing, a sump pit, and a pump. They manage water that is already at the wall and floor. The work happens inside, with part of the slab cut and replaced. It is generally less disruptive to landscaping, decks, and driveways.

Exterior systems involve excavating along the foundation, cleaning and sealing the wall, with membrane or coating, and installing drain tile and gravel. This stops water before it reaches the wall. It costs more in labor and tears up yards, patios, and plantings, and it is limited where the house sits close to a property line or has attached structures.

Some homes need both, or just simpler fixes like regrading, gutter extensions, and downspout drains. Ask any contractor why they chose their approach for your house, not just what they sell.
