Standing water, soggy grass, washed-out landscaping, and moisture near the foundation are all signs that water is not moving through your property as it should.
The right yard drainage contractor can identify where that water is coming from, determine where it can safely go, and recommend a solution that fits the property. The wrong contractor may simply install the drainage system they are most familiar with, whether or not it addresses the actual problem.
That is why the questions you ask before hiring matter.
You do not need to become a drainage expert before scheduling an estimate. You should, however, understand what the contractor is recommending, why they are recommending it, and what will happen once the digging starts.
Use the questions below to compare yard drainage contractors and make a more informed decision about your property.
Start With the Drainage Problem
Before discussing pipe, gravel, or equipment, make sure the contractor understands what is happening in your yard.
Water problems can come from several sources, including:
- Improper grading
- Downspouts releasing water too close to the house
- Runoff from neighboring properties
- Low areas that trap surface water
- Compacted soil that drains slowly
- Water moving toward the foundation
- A damaged or undersized drainage system
- Multiple water sources affecting the same area
A French drain may be appropriate for one property, while another may need grading, catch basins, downspout corrections, a swale, or a combination of solutions. The goal is not to choose a product first. It is to understand the water first.
1. What Is Causing the Drainage Problem?
A contractor should be able to explain more than where the puddle forms.
Ask what they believe is causing the water to collect and how they reached that conclusion. They may need to evaluate the slope of the yard, roof runoff, soil conditions, nearby hard surfaces, discharge locations, and how the area behaves during or after rainfall.
A useful answer should connect the cause to the proposed repair.
For example, if runoff is moving toward the foundation because the soil slopes inward, adding a drain may collect some water, but correcting the grade could also be part of the solution. Likewise, a catch basin will not help much if it has nowhere appropriate to release the collected water.
Be cautious when someone recommends a system before examining the full property.
2. Have You Completed Similar Yard Drainage Projects?
General excavation or landscaping experience does not always translate into drainage experience.
Ask whether the contractor has handled problems similar to yours. A yard that holds surface water presents a different challenge than a property where downspouts are overwhelming one area. Drainage near a foundation also requires different planning than drainage at the back of a large lot.
Helpful follow-up questions include:
- How often do you perform yard drainage work?
- Have you worked with similar soil and grading conditions?
- Can you show examples of completed projects?
- Can you explain what was installed and why?
- Have you worked in this community or nearby suburbs?
Local experience can be especially valuable because lot sizes, soil conditions, neighborhood layouts, and municipal requirements vary across the Chicago suburbs.
3. What Type of Drainage System Do You Recommend?
Ask the contractor to identify the specific system or combination of improvements included in the proposal.
Common yard drainage solutions may include:
- Regrading low or improperly sloped areas
- Extending or burying downspout lines
- Installing catch basins
- Installing French drains
- Adding channel or trench drains
- Creating drainage swales
- Connecting multiple drainage components
- Correcting an existing system
- Directing collected water to a suitable discharge point
The contractor should explain what each component does. You should not be left trying to decode a proposal filled with product names and construction terms.
It is also fair to ask whether another solution was considered. A good contractor should be able to explain why the recommended approach makes more sense for your yard.
4. Where Will the Water Go?
This is one of the most important questions in the entire conversation.
Collecting water is only half the job. The system also needs a safe and practical place to release it.
Ask the contractor:
- Where will the drainage line discharge?
- Will water remain on my property?
- Could the discharge create erosion or another wet area?
- Will it affect a neighboring property?
- Does the outlet remain usable during heavy rain?
- How will the discharge point be protected from clogs or damage?
A drainage system needs a workable outlet and enough fall to move water in the intended direction. French drains and similar systems also depend on proper design, slope, materials, and placement rather than the pipe alone.
If the contractor cannot clearly show where the water will go, the plan is not complete yet.
5. Did You Evaluate the Entire Property?
The visible wet spot may not be where the drainage problem begins.
Ask whether the contractor looked at:
- The grade around the home
- Gutters and downspouts
- Patios, driveways, and walkways
- Window wells
- Foundation walls
- Neighboring elevations
- Existing underground drainage
- Landscaping and retaining walls
- The proposed discharge area
Water may travel across or beneath the property before appearing in one low area. Looking only at the puddle can lead to a repair that treats the symptom instead of the source.
The contractor should also ask you questions. Be prepared to explain when the water appears, how long it remains, whether the problem has changed, and whether you have noticed basement or crawl space moisture.
Pictures and videos taken during heavy rainfall can be extremely helpful. By the time the contractor arrives, the yard may look perfectly innocent.
6. What Is Included in the Written Scope?
A verbal explanation is helpful, but the final estimate should spell out what you are paying for.
The written scope should identify details such as:
- Drainage system type
- Approximate placement and dimensions
- Pipe or basin materials
- Excavation work
- Discharge location
- Connections to downspouts or other systems
- Soil removal or redistribution
- Backfilling
- Surface restoration
- Cleanup
- Permit responsibilities, when applicable
- Warranty coverage
Ask what is not included as well.
For example, will the contractor replace disturbed sod, seed the area, restore decorative stone, move landscaping, or repair irrigation lines? There is no single correct answer, but you should know what the finished yard will look like and which restoration tasks remain your responsibility.
7. How Will You Protect My Property?
Yard drainage work often involves trenching, soil removal, and equipment moving through the property.
Ask how the crew will protect:
- Driveways and sidewalks
- Fences and gates
- Trees and established landscaping
- Irrigation systems
- Utility lines
- Patios and outdoor structures
- Areas used to access the worksite
You should also ask how underground utilities will be located before excavation begins.
Some disruption is normal. A drainage contractor should still have a plan for controlling it, keeping the work area organized, and restoring the property as closely as the agreed scope allows.
8. Are You Properly Insured?
Ask for proof of current insurance rather than relying only on a statement in a brochure or on a website.
Coverage should be appropriate for the type of excavation and drainage work being performed. You may also want to ask whether employees and subcontractors working on the property are covered.
Requirements can vary depending on the community and the type of work involved. Ask the contractor whether permits, inspections, or local approvals are necessary and who will be responsible for handling them.
A professional contractor should be comfortable answering these questions.
9. Who Will Complete the Work?
The person who provides the estimate may not be the person managing the installation.
Ask:
- Will your employees perform the work?
- Will subcontractors be involved?
- Who will supervise the project?
- Who should I contact with questions?
- Will the original estimator review the completed work?
There is nothing automatically wrong with using subcontractors. The important issue is accountability.
You should know who is responsible for the job, who understands the original plan, and who will respond if conditions in the yard require an adjustment.
10. How Much Will the Project Cost?
A useful yard drainage estimate should include more than one total at the bottom of the page.
Ask the contractor to explain:
- What labor and materials are included
- Whether restoration is included
- What could change the final price
- How unexpected underground conditions are handled
- Whether deposits or progress payments are required
- When the final payment is due
Yard drainage pricing can vary significantly based on system type, property elevation, soil conditions, access, excavation depth, and the size of the affected area.
Comparing estimates based only on price can be misleading. Two contractors may appear to quote the same project while using different materials, depths, outlet locations, or restoration plans.
Compare the complete scope, not just the number.
11. How Long Will the Work Take?
Ask for a reasonable project timeline and find out what could affect it.
Weather matters during excavation. Heavy rain can delay work, saturate the soil, or make it difficult to restore the yard. Equipment access, utility locations, permit requirements, and unexpected underground obstacles may also affect the schedule.
Questions worth asking include:
- When could the project begin?
- How many working days are expected?
- Will the system be usable immediately?
- What happens if it rains during installation?
- Will equipment or materials remain at the property overnight?
- When will the yard be restored?
12. What Warranty and Maintenance Are Provided?
Drainage warranties can differ considerably, so ask for the terms in writing.
Find out:
- What parts of the work are covered
- How long the coverage lasts
- What conditions could void the warranty
- Whether settling or surface restoration is covered
- Who to contact if water still collects
- Whether a follow-up inspection is included
You should also ask what maintenance the system will need.
Catch basins may need debris removed. Drainage outlets should remain open. Buried downspout lines and French drains may need inspection if water stops flowing as expected. Landscaping changes can also alter how water moves through the yard.
A drainage system should not feel mysterious after installation. You should know how it works and how to keep it working.
Warning Signs During an Estimate
One awkward answer does not necessarily mean a contractor is unqualified. A pattern of vague or evasive answers deserves more attention.
Pause before hiring when a contractor:
- Recommends a system without inspecting the property
- Cannot explain what is causing the problem
- Does not identify a clear discharge location
- Provides only a verbal price
- Avoids questions about insurance
- Pressures you to decide immediately
- Offers a warranty without written terms
- Cannot explain who will perform the work
- Leaves restoration and cleanup unclear
- Dismisses concerns about water reaching neighboring properties
A qualified contractor should make the project easier to understand, not harder.
How to Compare Yard Drainage Estimates
Once you have gathered estimates, place them side by side and compare the same categories.
Diagnosis
Do the contractors agree about where the water originates? When they disagree, which explanation is supported by the property conditions?
Proposed Solution
Are they recommending the same type of drainage system? Does each proposal explain why that system fits the problem?
Water Outlet
Where does each system send the water? Is that location practical during a large rain event?
Materials and Installation
Compare the pipe, basins, gravel, fabric, depth, connections, and other installation details listed in each scope.
Property Restoration
Determine what happens to the lawn, landscaping, soil, walkways, and access route after the system is installed.
Warranty
Compare what is covered, how long it is covered, and what you must do to maintain that coverage.
Communication
Consider how clearly each contractor answered your questions. The estimate process often provides a useful preview of how communication will feel once the project begins.
The lowest proposal is not automatically the wrong choice, and the highest is not automatically the most complete. The goal is to identify the plan that makes sense, is clearly documented, and addresses the actual movement of water.
Questions to Ask Yourself Before Signing
- Do I understand what is causing the water problem?
- Do I understand why this solution was recommended?
- Do I know where the collected water will go?
- Is the complete scope written down?
- Do I know what the yard will look like afterward?
- Are the price and payment terms clear?
- Do I understand the warranty?
- Do I know who will be accountable for the work?
If any answer is no, ask for clarification before signing.
A professional contractor should not make you feel uncomfortable for wanting to understand work being completed on your own property.
