In clay soils, which is more cost‑effective: lot grading or interior drainage retrofits?
For clay soil, regrading your yard is the cheaper way to keep water away from your foundation and cut down on upkeep, as long as there’s nothing in the way. Indoor fixes like French drains cost more upfront, mess up your house more, and need regular attention.
Basically, sort out the yard’s slope first. If water still gets in, then think about indoor solutions.
The most cost-effective solution depends on your specific situation, including property size, soil conditions, and budget. Consult with a professional to determine the best approach for your needs.
