Grading + Drainage
Water problems rarely fix themselves.
Standing water, erosion, soggy turf, and foundation concerns are symptoms. The real work is understanding where the water comes from, how it moves across the property, and where it can safely go.
We evaluate the entire site before recommending a solution. That may include grading, collection, conveyance, downspout management, or a combination designed specifically for your property.
What the service includes
A complete approach to grading + drainage.
Grading Solutions
Thoughtful elevation changes help move surface water while preserving usable lawn and existing landscape features.
Drainage Systems
French drains, catch basins, solid pipe, channel drains, and discharge points are selected for the actual problem.
Downspout Management
Roof water is captured and carried away from foundations, planting beds, walks, and chronically wet areas.
A real drainage transformation
From active problem to lasting solution.
Good drainage work is rarely about one visible drain. It is about reading the property, building the right path for water, and restoring the landscape so the solution feels like it belongs there.

Why the details matter
Water always finds a path. We make sure it is the right one.
A drain in the wrong place can simply move the symptom. Our approach begins with the larger water story—source, volume, elevation, soil, and discharge—so the solution protects the whole property.
Built correctly underground
The details you may never see are the ones that make the system last.
Proper trenching, pipe selection, downspout connections, slope, and discharge planning determine whether a drainage system actually solves the problem.

Training that reaches the jobsite
A team that understands the why.
Anyone can bury a pipe. The real value is understanding why the water is there, how it moves across the property, and where it can be directed responsibly. That knowledge does not stop with the owner. We have invested in NDS Professional Drainage Contractor training for multiple members of our team, so the people assessing, planning, and installing your system share a deeper understanding of drainage—not just a set of instructions.
Better diagnosis
We look beyond the visible puddle to identify sources, grades, volume, soil, and flow paths.
Thoughtful system selection
Materials and drainage components are chosen for the actual site conditions—not from a one-size-fits-all recipe.
Knowledge at every step
The people installing your system understand why each component is there, how it should perform, and what proper installation requires.
Our process
Clear from the first conversation.
We make the next step easy to understand, keep expectations realistic, and stay accountable through completion.

Walk the property, discuss when the issue occurs, and identify visible symptoms.

Study grades, sources, flow paths, soil, and safe discharge options.

What Clients Say About Our Drainage Solutions
“We has drainage issues with some existing underground downspout drains. Tom came up with some solutions to get the outlets further from the home and prevent standing water where they terminate. Brennans also installed a channel drain across a sidewalk to prevent the flower beds from filling with rainwater during thunderstorms.”
