French Drain and Yard Drainage Cost & Process in Alabama

A French drain and yard drainage project in Alabama should start with a written scope that separates the core job from optional upgrades. In scope for this guide: diagnosing runoff, laying out swales, catch basins, French drains, downspout extensions, solid or perforated pipe, gravel, fabric, discharge points, daylight outlets, sump tie-ins where allowed, backfill, and surface restoration. The contractor should also define dust control, protection of existing finishes, work hours, debris removal, daily site cleanup, product allowances, and who communicates inspection dates. This is the practical middle of the market: more than a single repair visit, but less than a custom whole-house reconstruction.

Out of scope unless the proposal says otherwise: foundation structural repair, basement interior waterproofing, sewer work, municipal storm connection, retaining walls, major grading, irrigation redesign, and landscaping beyond disturbed areas unless included. Those items can be legitimate, but they change risk, schedule, permits, and the trades required. The safest contract names the prime contractor, each licensed trade, the products or allowances, payment milestones, and the conditions that trigger a written change order. Alabama licenses general contractors statewide through the Alabama Licensing Board for General Contractors and electricians through the Alabama Electrical Contractors Board. Plumbing and HVAC are licensed through the Alabama Plumbers & Gas Fitters Examining Board and Board of Heating, Air Conditioning & Refrigeration Contractors. For this project, relevant credential checks commonly point to: Alabama Licensing Board for General Contractors; Alabama Plumbers & Gas Fitters Examining Board.

The state-content-2026-06 costBand for Alabama lists General contractor remodel at $5,000 low, $25,000 typical, and $75,000 high. Drainage is priced below a remodel but rises with trench length, depth, pipe type, gravel volume, fabric, basins, discharge distance, machine access, soil disposal, and restoration. After that project adjustment, a planning range for this French drain and yard drainage project is $900 low, $5,500 typical, and $15,000 high.

Use those figures as a budget screen, not a quote. The low end assumes standard access, ordinary finishes, no major hidden damage, and a clean permit path. The high end reflects premium materials, difficult access, older homes, multiple inspections, structural or utility coordination, and change orders discovered after opening walls, roofs, or equipment spaces. For bid comparison, ask each contractor to separate labor, materials, permit fees, allowances, disposal, access assumptions, and change-order rates so a low headline price does not hide missing scope. For larger scopes, ask whether the bid assumes owner-supplied products, occupied-home protection, temporary utilities, final cleanup, disposal, and return trips after inspections. Confirm mobilization, warranty exclusions, sales tax assumptions, and documentation responsibilities separately for every bid before signing.

Drainage work may need permits when discharge reaches a storm system, right-of-way, wetlands, slopes, easements, or neighboring properties. Some cities restrict sump and downspout connections. The state licensing source matters because a contractor license or registration is not the same thing as a project permit. Alabama licenses general contractors statewide through the Alabama Licensing Board for General Contractors and electricians through the Alabama Electrical Contractors Board. Plumbing and HVAC are licensed through the Alabama Plumbers & Gas Fitters Examining Board and Board of Heating, Air Conditioning & Refrigeration Contractors. Home improvement is registered separately through the AG's Home Builders Licensure Board for residential work over $10,000. The project-specific licensing notes in the seed say: required at or above $50,000 through Alabama Licensing Board for General Contractors; Required for commercial jobs >=$50K and swimming-pool work >=$5K. required at or above $10,000 through Alabama Home Builders Licensure Board; Residential builder license required for residential work over $10,000. required through Alabama Plumbers & Gas Fitters Examining Board

For permits, verify the authority having jurisdiction before signing: city building department, county building department, consolidated permit office, or in some areas a separate utility or fire review. Ask who pulls the permit, whose license appears on it, whether owner-builder filing is allowed, which inspections occur before work is covered, and whether final approval is required before final payment. Keep the permit card, inspection approvals, and stamped plans or online permit record with the contract.

Small drainage runs can take one to three days, while design review, utility marking, saturated soil, heavy equipment access, permits, and surface restoration can create a two- to six-week window. Alabama projects must account for humid summers, thunderstorms, and heat exposure during material handling. Build in float for afternoon storms, high attic temperatures, and seasonal demand spikes after severe weather.

Because permit review is municipal rather than one statewide queue, treat the timeline as two tracks: approval and inspection scheduling on one side, materials and crew availability on the other. A contractor who gives a firm start date should also name the permit filing date, long-lead products, inspection hold points, and weather or utility conditions that can move the calendar.
