Who They're For and What They Solve
Drainage and stormwater management is the engineered control of water movement across and beneath a property. It combines subsurface systems that intercept groundwater with surface work that redirects rainfall by gravity, sending both to a safe discharge point instead of letting them collect against structures.
Property owners need it when rainfall arrives faster than soil can absorb it. Clay-heavy soil, flat or reverse grading, downspouts discharging beside foundations, and hardscape that blocks natural flow all create the same result: water with nowhere to go and no path out.
Left alone, trapped water works downward. It saturates footings, seeps into basements and crawlspaces, drowns root systems, and undermines patios until they settle and crack. Correcting the flow path early costs a fraction of repairing the structural damage that follows.
Is It Time?
Most property owners notice these before they know what causes them.
Our Services
We use four core methods, selected by where your water originates and where it can legally go.
A perforated pipe set in a gravel-wrapped trench that intercepts groundwater below the surface and carries it to discharge. This is the right method when soil stays saturated between rains or water surfaces mid-slope. Result: the water table drops and soil dries out.
Reshaping soil contours so gravity moves water away from structures, often with a shallow vegetated channel to guide flow. Best when grading is flat or pitched toward the building. Result: rainfall leaves the area before it can collect.
Inlet boxes and buried piping that capture concentrated runoff from roofs, driveways, and low points, then carry it underground to a safe outlet. Best for high-volume, single-point water. Result: no more discharge pooling beside your foundation.
Underground chambers that hold runoff and release it slowly into surrounding soil. Used when no street or property-line discharge point exists, or when retention volume is required. Result: compliant storage with no surface flooding.

Why Homeowners Choose Mr. Local Services
We walk the property, identify the actual water source, and measure existing slope before quoting anything. Most assessments are scheduled within two business days of your call.
You receive a fixed written price covering materials, labor, discharge, and restoration. No hourly billing, no mid-project change orders, no surprises after the digging starts.
If water returns to the treated area within five years, we come back and correct it at no charge. That warranty is why we calculate slope instead of estimating it.
Trenches are backfilled, grade is matched, and sod or seed is replaced. Your property looks finished when we leave not like a worksite someone abandoned.
How It Works
Call 951-458-6466 and describe where water collects. We schedule an on-site visit, typically within 48 hours.
We help you choose layouts, fixtures, tile, and finishes that fit your style and budget, then finalize a clear project plan and timeline before work starts.
You get the recommended method, system layout, materials, timeline, and one fixed price. Most residential projects run two to four days.
We excavate, install to calculated slope, water-test the system under flow, backfill, and restore turf and grade before final walkthrough.
Pricing
We publish real numbers because guessing wastes your time. Final pricing depends on four measurable factors.
Cost factors: total system length, excavation depth, soil type and rock content, and distance to a viable discharge point.
Typical ranges: French drain systems run $2,200–$6,500 for most residential runs. Surface grading and swale work runs $1,800–$5,000. Catch basin and downspout drainage runs $1,400–$4,200. Dry wells and retention systems run $3,000–$9,500.
Commercial and compliance-driven projects are quoted after site review. Every number you receive is flat-rate and in writing before we dig. Call for your free assessment and exact figure.
It depends on whether water is sitting on the surface or held in the soil. Our assessment determines which, and regrading is often the cheaper correct answer.
Most residential drainage systems are completed in two to four working days, including excavation, installation, water testing, and full turf restoration.
No. We backfill, match existing grade, and replace sod or seed across all disturbed areas as part of the quoted flat-rate price.
Yes. Our 5-Year No-Standing-Water Warranty covers the treated area. If water returns, we return and correct the system at no charge.
Yes. We are a licensed landscape contractor, grading and erosion control certified, and carry $2M general liability plus workers' compensation.
Often yes, and it saves money. If you are already planning changes, our landscape design services page shows how drainage is built into the plan from the start rather than retrofitted later.
Call 951-458-6466. We schedule your free on-site assessment, usually within 48 hours, and quote a fixed price after.
Every storm that passes moves more soil and more moisture toward your foundation. Book your free assessment now and get a flat-rate written plan backed by our 5-year warranty.
