Before you dig one shovel or buy one roll of pipe, get a real plan. We come to your property, shoot the grades, measure the water, and hand you an engineered drainage design built for how your yard actually floods.
Most drainage jobs fail because they were never designed — someone eyeballed a slope and buried some pipe. This evaluation gives you a documented, measured plan you can build to, hand to a contractor, or have us install.
A scaled site sketch showing drain runs, catch basins, pop-up emitters or daylight points, and discharge locations — keyed to real measurements.
Exact pipe sizes and the fall for every run, calculated to move your roof and yard water — not a one-size guess.
Every part the job needs — pipe, fittings, basins, emitters — priced and in stock locally, no freight, no waiting.
This is what separates a $500 professional evaluation from a free "we'll take a look." We bring the instruments and do the math.
We shoot elevations across the property with a laser/transit to map exactly which way water moves and where it pools — the fall you have to work with, to the inch.
We measure the roof planes and map every downspout, so we know how much hard surface is dumping water and where it lands.
We convert roof area and Northeast Florida rainfall intensity into peak flow (gallons per minute) for each downspout and collection point — sized for a real storm, not a drizzle.
Each run is matched to the flow it has to carry — 3.5", 4", or larger — using heavy-duty FDM HDPE, never thin box-store corrugated.
We set the fall on every run (minimum ~1%, about 1/8" per foot, more where grade allows) and route the system to a proper discharge — daylight, dry well, or sump.
Catch basins, sediment traps, pop-up emitters and cleanouts placed where the plan needs them — so the system performs and stays maintainable.
Call or request a time. We schedule an on-site evaluation across St. Johns, Duval, and surrounding counties.
We walk the property, shoot grades, measure the roof and downspouts, and find where the water actually goes.
We run the flow, sizing and slope numbers and design a system built for your property's storms.
You get the written plan, materials list and pricing — DIY it, hand it off, or have our crew install it.
Full professional evaluation, on-site measurements, flow & sizing calculations, and a documented drainage plan for your property.
Larger or multi-structure properties quoted after a quick call. Same-day material pickup once your plan is set.
Water that isn't moved correctly finds your foundation, your slab and your landscaping. A $500 plan built on real measurements is the cheapest insurance against a five-figure water problem — and it makes every dollar of pipe you buy actually work.
