Ask for a plan that covers the whole property—not just a price for digging a trench. Before hiring, you should understand which water problems the contractor will address, where the collected water will go, and what the work involves.
Start with these questions before comparing estimates.
Does the Drainage Contractor Have Experience With Properties Like Mine?
Ask for examples involving similar slopes, long driveways, established landscaping, and multiple drainage areas. Request references, and verify licensing and insurance rather than relying on a reassuring sales conversation. The Federal Trade Commission recommends checking credentials and getting written estimates before hiring a contractor.
Project photos show the finished appearance. References give you a chance to ask how the drainage performed afterward and how the contractor handled questions during construction.
Will the Drainage Plan Address Every Wet Area on My Property?
Ask the contractor to explain each problem area separately, then show how the proposed work fits together. Roof runoff, water crossing paving, and groundwater near the foundation require attention to different collection points and drainage routes.
For example, a surface drain collects water crossing a driveway, while a buried French drain intercepts water moving through the soil. Installing the same system everywhere isn’t a substitute for understanding those differences.
Where Will My Drainage System Send the Collected Water?
Have the contractor identify the outlet before agreeing to the installation. The discharge needs to carry water away without sending it back toward the house or eroding another section of the property.
If the proposal includes a dry well, ask about soil testing, storage capacity, and overflow. A dry well relies on the ground absorbing stored water, and it needs an overflow route for runoff beyond its design capacity. Extra space on a large property doesn’t replace suitable soil conditions.
What Should a Drainage Estimate Include for a Large Property?
Request a written scope covering excavation, drain locations, materials, discharge arrangements, grading, and restoration. Written estimates should identify the work, materials, schedule, and price so you understand what you’re agreeing to.
For an established property, get specific about stone walkways, planting beds, irrigation lines, and equipment access. Ask what stays in place, what needs removal, and who puts everything back.
Also clarify whether testing, engineering, and any required approvals are included or priced separately.
What Should I Ask About Drainage Maintenance and Warranty Coverage?
Ask which collection points need cleaning, where the inspection access points will be, and what maintenance the contractor recommends. Request a simple layout showing the installed drains and connections.
Get workmanship terms in writing, including the coverage period and how to report a problem. Don’t assume that a material warranty and an installation warranty cover the same things.
