Contractor Quote Checklist
Yard Drainage Quote Checklist Before Approval
Short answer: a yard drainage quote should explain where the water comes from, where it will go, what slope or drain system is being used, how deep and long any trench will be, who handles 811 utility marking, whether downspouts are included, what soil and debris will be removed, how grass, mulch, hardscape, and irrigation will be restored, what maintenance is required, what the warranty excludes, and what conditions trigger a change order. Do not approve a quote that simply says “install French drain” without a water-path plan.
Drainage quotes can sound confident while still leaving the homeowner exposed. One contractor may propose regrading, extending downspouts, adding catch basins, and restoring the lawn. Another may propose a French drain in the lowest area without explaining whether it has enough slope, a safe discharge point, or a maintenance plan.
The expensive mistake is paying for a drain that moves water from one problem area to another. A quote should show the diagnosis, not just the fix.
This checklist does not estimate local yard drainage cost. Drainage work depends on soil, slope, access, trench depth, pipe length, discharge point, hardscape, landscaping, and local rules. The goal is to help homeowners compare scope before signing.
Start With The Water Source
Before choosing a drain, the quote should identify the source of the water. A wet yard may be caused by roof runoff, downspouts, poor grading, compacted soil, a neighbor’s slope, driveway runoff, sump discharge, irrigation leaks, high groundwater, or a clogged existing drain.
- Where does water collect?
- When does it collect: during storms, after irrigation, or continuously?
- Does roof runoff discharge near the problem area?
- Are downspouts, sump lines, or driveway slopes contributing?
- Is the issue surface water, subsurface water, or both?
- Has an existing drain failed?
If the quote jumps straight to a product, the homeowner may be buying a guess.
Map Where The Water Will Go
Drainage work needs a destination. Moving water toward a neighbor, sidewalk, driveway, foundation, septic area, or erosion-prone slope can create another problem.
EPA’s green infrastructure resources and Soak Up the Rain materials are useful reminders that stormwater should be managed thoughtfully. A homeowner still needs local code and site-specific advice, but the quote should not ignore runoff destination.
- Where will the drain discharge?
- Is daylight discharge possible?
- Will water enter a storm drain, dry well, swale, rain garden, or approved outlet?
- Are local stormwater rules, HOA rules, or permits involved?
- Will the project create erosion at the discharge point?
- Will the discharge freeze across a walkway or driveway?
A drainage plan without a discharge plan is incomplete.
Separate Grading From Drain Installation
Some yards need grading before they need pipe. Others need a drain because grading alone cannot move water far enough. The quote should separate these scopes.
- Is soil being added or removed?
- What areas will be regraded?
- What slope is being targeted?
- Will grading affect patios, fences, sheds, trees, or AC pads?
- Is topsoil included?
- Is seeding, sod, mulch, or erosion control included?
Regrading can disturb landscaping and hardscape. If restoration is excluded, the lower quote may only be cheaper on paper.
French Drain Quotes Need Cross-Section Detail
“Install French drain” is not enough. The quote should describe the trench and materials.
- Trench length
- Trench depth and width
- Pipe type and diameter
- Perforated or solid pipe sections
- Fabric wrap or soil separation method
- Stone type and depth
- Cleanout locations
- Discharge point
- Surface restoration
A shallow decorative trench and a properly scoped subsurface drain are not the same job.
Catch Basins Need Maintenance Access
Catch basins can help collect surface water, but they can also fill with leaves, mulch, and sediment. The quote should explain basin size, grate type, pipe connection, and cleaning access.
- How many basins are included?
- Where will they be placed?
- What grate type will be used?
- What pipe connects the basin to the outlet?
- Can the basin be cleaned easily?
- Will mulch, leaves, or lawn debris clog the system?
If the system cannot be maintained, it may fail after the first season of debris.
Downspout Routing Should Be Written Clearly
Downspout extensions are often part of yard drainage work, but they are not automatically included. The quote should say which downspouts are included and where they go.
- Which downspouts are being extended?
- Will the line be solid pipe, pop-up emitter, daylight outlet, or other discharge?
- Will the line connect to a French drain or stay separate?
- Are cleanouts included?
- Will buried lines cross tree roots, utilities, patios, or walkways?
- How will roof debris be kept out of the system?
Mixing downspouts into perforated pipe without explanation can overload or clog the system.
Utility Marking Is Not Optional When Digging
Drainage work often requires trenching. The Pipeline and Hazardous Materials Safety Administration’s Call Before You Dig guidance points homeowners to 811 before digging so buried utility lines can be marked.
- Who requests 811 marking?
- When will marking be requested?
- Will the contractor adjust the layout if utilities conflict?
- Who handles irrigation, landscape lighting, private drains, or invisible fence lines?
- What happens if hand digging is required near marked utilities?
Public utility marking may not cover private lines. The quote should explain that risk before excavation starts.
Trenching And Excavation Risk Should Be Scoped
Even a residential drainage project can involve trenching, heavy soil, roots, rocks, narrow access, and equipment damage. OSHA’s trenching and excavation guidance is aimed at worker safety, but it highlights why trenching is real construction work rather than a simple yard chore.
- Will work be hand-dug or machine-dug?
- What access path will equipment use?
- Will plywood or mats protect lawn and hardscape?
- How will tree roots be handled?
- What happens if rock, buried concrete, or old pipe is found?
- Are trench settlement repairs included?
The quote should say what hidden conditions are included and what becomes extra.
Soil, Sod, And Landscape Restoration Can Be A Large Scope
Drainage work can leave piles of soil, torn sod, disturbed mulch, cut edging, and damaged irrigation. The quote should say what the yard will look like when the crew leaves.
- Is excavated soil hauled away or reused?
- Is excess clay or wet soil disposal included?
- Will lawn be seeded, strawed, sodded, or left rough?
- Are mulch beds, edging, plants, and decorative stone restored?
- Who repairs irrigation lines or landscape lighting?
- Is final grading included after trench backfill settles?
A quote that excludes restoration should be compared against the cost of hiring someone else to clean up the yard.
Hardscape Crossings Need Their Own Line Item
Drain lines may need to cross sidewalks, patios, driveways, retaining walls, edging, or fences. That work can change the price and risk.
- Will any concrete or pavers be removed?
- Will the contractor tunnel under hardscape?
- Who restores pavers, gravel, concrete, or edging?
- Will the project affect fences or gates?
- Are permits needed for work near public sidewalks or curbs?
Do not assume hardscape repair is included unless it appears in writing.
Maintenance Should Be Part Of The Buying Conversation
Drainage systems are not maintenance-free. Grates clog, outlets block, sediment accumulates, roots grow, and pop-up emitters can get covered.
- What parts need cleaning?
- How often should basins be checked?
- Where are cleanouts located?
- Can the homeowner flush the line?
- What signs show the system is clogged?
- Is maintenance required to keep the warranty valid?
If the system requires annual cleaning, the homeowner should know before approval.
Warranty Language Should Match The Drainage Reality
Drainage warranties can be narrow. A contractor may warranty workmanship but not guarantee that every storm, soil condition, neighbor runoff issue, or groundwater problem disappears.
- What is warranted: pipe, labor, grading, outlet, or system performance?
- How long does the warranty last?
- Are clogs excluded?
- Are extreme storms excluded?
- Are neighbor runoff, groundwater, or changed landscaping excluded?
- What maintenance is required?
A drainage quote should be honest about limits. Overpromising is a warning sign.
Payment Schedule And Change Orders Need Guardrails
Drainage contractors may ask for a deposit, progress payment, and final payment. The homeowner should connect payment to visible milestones.
- Deposit amount
- Material delivery or start date
- Excavation completion
- Pipe, stone, basin, and outlet installation
- Backfill and restoration
- Final walkthrough
The FTC’s home improvement scam guidance is relevant for any residential contractor project. Be careful with vague scope, pressure, cash-only requests, and large upfront payments without clear contractor details.
Yard Drainage Quote Review Table
| Quote Area | What Should Be Written | Why It Matters |
|---|---|---|
| Water diagnosis | Source of water, collection area, timing, and likely cause. | The fix should match the real problem. |
| Discharge plan | Where water exits or infiltrates, plus local rule assumptions. | A drain cannot simply move water to a worse place. |
| Drain system | Pipe, stone, fabric, basin, cleanout, trench depth, and length. | Product names alone do not define the scope. |
| Utility marking | 811 responsibility and private-line risk. | Drainage work usually involves digging. |
| Restoration | Soil handling, lawn repair, mulch, irrigation, and final grading. | Cleanup can be a large hidden cost. |
| Warranty | Workmanship, performance limits, clog exclusions, and maintenance. | Drainage systems have realistic limits. |
Questions To Ask Before Approval
- What water source is this quote solving?
- Where will the water go after the work?
- Is the solution grading, French drain, catch basin, downspout routing, or a mix?
- What trench length, depth, pipe, stone, fabric, and cleanouts are included?
- Who calls 811?
- Who handles private irrigation or landscape lighting lines?
- What soil, sod, mulch, and hardscape restoration is included?
- What maintenance is required?
- What drainage result is not guaranteed?
- What hidden conditions trigger a change order?
Approval test: before signing, the homeowner should be able to point to the water source, the drain path, the discharge point, the excavation area, the restoration scope, and the warranty limits on the written quote.
Red Flags In A Yard Drainage Quote
- The quote names a French drain but does not show where water discharges.
- No one discusses slope.
- Downspouts are ignored even though roof runoff is part of the problem.
- 811 marking is not mentioned.
- Private irrigation or landscape lighting lines are ignored.
- Restoration is vague.
- Cleanouts and maintenance are not discussed.
- The contractor guarantees that the yard will never be wet again.
- Payment is front-loaded before materials or work begin.
FAQ
What should a yard drainage quote include?
It should include the water source, proposed drain path, discharge point, grading scope, pipe or basin details, trench depth and length, 811 utility marking, private-line responsibility, soil handling, lawn and landscape restoration, maintenance needs, warranty limits, payment schedule, and change-order rules.
Is a French drain always the right yard drainage fix?
No. Some problems are better addressed with downspout extensions, regrading, swales, catch basins, surface drains, soil improvement, or a combination. The quote should explain why the proposed method matches the water source and discharge path.
Who is responsible for calling 811 before drainage work?
The quote should say who requests 811 marking and when. Public utility marking may not cover irrigation, landscape lighting, private drain lines, invisible fence, or other private lines, so that responsibility should also be written.
Should yard drainage quotes include lawn restoration?
They should clearly state whether restoration is included. Drainage work can disturb soil, sod, mulch, plants, edging, irrigation, and hardscape. If restoration is excluded, the homeowner may need a second budget.
Why do yard drainage quotes vary so much?
They vary because one quote may include diagnosis, grading, pipe, stone, fabric, basins, downspouts, cleanouts, utility precautions, soil disposal, restoration, and warranty, while another may only include a basic trench or drain line.
