About French Drain Installation & Repair
Interior and exterior French drain systems — professionally designed for your property's specific drainage needs.
Interior and exterior French drain systems for basements, crawl spaces, foundations, and yards. We design drainage systems based on the specific water flow patterns of your property — accounting for soil type, grading, and water table levels. Our French drains use commercial-grade pipe, proper aggregate, and filter fabric to prevent clogging and ensure decades of performance.

Frequently Asked Questions
Interior French drains are installed inside the basement perimeter along the footer to collect water that has already entered and direct it to a sump pump. Exterior French drains are installed outside the foundation to intercept water before it reaches the walls. Both have appropriate applications — the right choice depends on your specific water source, property conditions, and budget. We evaluate and recommend based on what will actually solve the problem at your Birmingham property.
French drain costs depend on the length, depth, whether it is interior or exterior, soil conditions, and any obstacles like utilities or landscaping. We provide detailed evaluations for Birmingham properties and include all associated work in our proposals — excavation, materials, backfill, and site restoration.
