Diagnosis and installation for standing water, downspout runoff, soggy lawns and patio drainage problems.
DCM Outdoor evaluates where the water originates, how it travels across the property and where it can be discharged safely before recommending a drain. Solutions may include grading corrections, catch basins, solid downspout piping, French drains, channel drains, swales or coordinated patio repairs.
We evaluate roof discharge locations, visible flow patterns, existing grades and the proposed patio elevation. We inspect observable drainage patterns and may recommend a licensed surveyor or engineer when elevations or stormwater requirements require one.
Roof, irrigation, surface sheet flow, groundwater saturation, or runoff from an adjacent area.
Where water wants to go today — and whether a safe daylight, basin or approved connection exists.
Trench routes, hardscape cuts, plant protection and practical installation access.
A legal, workable outlet — not “off the yard” onto a neighbor or unapproved public structure.
Whether HOA review, municipal stormwater rules, permits, engineering or surveying apply to the scope.
Dry wells or infiltration devices are only recommended where soil and groundwater conditions allow infiltration — Charleston-area soils vary property to property.

DCM Outdoor will not intentionally redirect runoff onto an adjoining property. Projects involving public drainage systems, easements, rights-of-way or significant grading may require approval or design by the applicable municipality or another qualified professional.
Charleston County manages applicable runoff through permitting and inspections; work that affects a county right-of-way or public drainage structure may need review under the Charleston County Stormwater Program. City or town rules may also apply depending on the address.
We are building a dedicated drainage case library (standing water after rain, trench and bedding, verified outlet, finished grade, and results after the next storm). Until those five documented projects are published, here is related hardscape and site work photography.
Every lot proves different — discharge distance, depth, hardscape cuts and restoration drive price more than pipe brand.
We quote after a drainage inspection — not from a photo of a puddle. Educational cost context also lives on the yard drainage guide.
Catch basins and channel drains need periodic debris clearing. French-drain performance depends on keeping silt out of the envelope and protecting the outlet. Downspout ties should stay connected after storms and gutter cleaning.
Workmanship and materials coverage are stated in your proposal for the installed scope. Drainage performance still depends on storm intensity, groundwater, irrigation habits and any later grade changes on the property — we do not promise a yard that never holds water after every coastal storm.
The fastest path to local authority is documenting five Charleston-area drainage projects with: standing-water condition after rainfall, flow assessment, trench and bedding, pipe and basin materials, verified outlet, finished grade and sod, results after the next heavy rain, and a customer review that mentions drainage or standing water.
Until those pages are live, browse related outdoor living work on our work, patio flooding context on patio flooding, and slope basics on paver patio drainage & slope.
Read verified feedback on our reviews page. Map Pack leaders win with years of Google reviews and strong Business Profiles — DCM is building drainage-specific reviews from real installs, not invented quotes here.
Donovan leads drainage inspections and coordinates installation with patio, landscape and outdoor living scopes when those are part of the same project. When elevations, stormwater design or regulated connections require a licensed surveyor or engineer, DCM coordinates that professional rather than implying DCM performs professional land surveying or engineering.
Common causes include roof downspouts discharging near the foundation, flat or reverse grades, builder berms and fences that trap runoff, hardscape that drains poorly, neighboring runoff, and soils that drain slowly after rain. Soil conditions vary by property — we diagnose your lot rather than assuming every Lowcountry yard behaves the same.
Yes. Catch basins, solid downspout piping, French drains, channel drains, swales, dry creek beds, targeted regrading and paver drainage or re-pitching are all in scope when they fit the diagnosis.
No. DCM Outdoor will not intentionally redirect runoff onto an adjoining property. Public systems, easements, rights-of-way or significant grading may need municipal approval or another qualified professional.
Usually yes when standing water or poor pitch already exists. We evaluate roof discharge locations, visible flow patterns, existing grades and the proposed patio elevation so you are not cutting new pavers later. Related: paver patios.
Minor downspout and grading work often falls in the high hundreds to low thousands. French drain systems with proper outlets commonly run mid single-digit thousands and up. Integrated grading and hardscape pitch fixes can reach five figures. We quote after inspection.
Use the yard drainage guide to learn how systems work, French vs channel to compare options, patio flooding for hardscape symptoms, and flood-zone landscaping for planning considerations — then hire from this service page.
We will walk the property, identify source and outlet options, and tell you whether the fix is grading, a targeted drain, patio re-pitch — or coordination with another professional — before you buy pipe you do not need.
