Grading & Regrading
Reshaping the ground so surfaces slope away from the house and toward a planned outlet.
Trade 11 · Drainage & Grading
Site drainage and grading solutions that move water intentionally and protect the finished work.
Sub-services
Reshaping the ground so surfaces slope away from the house and toward a planned outlet.
Shallow, shaped channels that carry surface water across the yard.
Perforated pipe in drain rock that collects and carries subsurface water.
Inlets that collect water from low spots, patios and driveways.
Piping roof water away from the foundation to a planned outlet.
Drainage planned with patios, walls and turf so finished surfaces stay sound.
Drainage & Grading
In our wet climate, water that has nowhere to go ends up in the wrong place: standing on a lawn, against a foundation, behind a wall or under a patio. Over time that causes settling, erosion and damage.
The fix starts with understanding where the water comes from and where it should go. We plan the outlet first, then the path to get water there.
What good looks like
Make it yours
Swales and grading handle surface water; French drains and area drains handle subsurface or collected water.
Options include daylighting to a lower area, connecting to an approved storm system or infiltrating where the soil allows.
Solid pipe carries water; perforated pipe collects it. Inlets and basins are chosen for the flow and the traffic.
Some drainage is buried; some, like rock-lined swales, can be a landscape feature.
Some swales and rain gardens use plants to slow and absorb water.
Suppliers & collections
Pipe, basins, fabric and related drainage products come from suppliers we work with or can source through. We confirm availability and specifications during design and estimating. Product availability, colors and pricing can change, so a saved link is a selection request, not a guarantee.

Explore all materials6 Steps
We walk the property in wet conditions where possible and look at grades, downspouts, soil and problem areas.
We identify where the water can go and what approvals or rules apply.
Trenches or swales are cut to the planned slope so water moves by gravity.
Pipe is set with proper bedding, wrapped or lined with fabric where needed and surrounded by drain rock.
Connections are completed and the system is tested with water to confirm flow.
The surface is restored, final grades are shaped and the site is cleaned.
Workmanship coverage and credentials are confirmed in writing with your proposal.
Factors, not prices
A single wet spot differs from drainage across a whole yard.
Longer runs to a suitable outlet mean more trenching and pipe.
Hard digging, rock and soil removal change the groundwork.
Swales, French drains, basins and pipe all carry different scope.
Narrow access and long carries affect labor and equipment.
Restoring lawn, planting or hardscape after trenching is part of the work.
Every property is different. After we assess yours, your proposal sets out the written scope, options and pricing assumptions.
Drainage & Grading
It depends on the cause. We assess where the water comes from and recommend what will help. Some conditions may need additional steps or professional engineering.
We plan an outlet first, which could be a lower area on the property, an approved storm connection or an infiltration area where soil allows. Local rules affect the options.
Yes. Routing downspouts away from the foundation to a planned outlet is a common part of drainage work.
Some do. Catch basins and inlets can collect debris and may need occasional cleaning. We review care at the walkthrough.
The extent of the problem, outlet distance, soil, system type and access all play a role. You receive a written scope and pricing after the assessment.
