Stop Water Before It Causes Damage

Professional storm water drainage installation to control runoff and protect your property from flooding.

When heavy rain hits your property, water needs somewhere to go. Without a drainage system designed to handle the flow, runoff pools near your foundation, washes out driveways, and leaves your landscaping submerged and eroded. You notice the puddles that refuse to drain, the gullies forming along your slopes, and the settling that threatens the stability of everything you built.


Stanley Excavation & Grading installs storm water drainage systems that redirect runoff away from structures and vulnerable areas. Each system is customized to your property's slope and flow patterns, integrating with grading and erosion control to ensure water moves where it should. The installation includes trenching, pipe placement, catch basins, and outlet points that work with your land rather than against it.


Schedule a drainage evaluation to see what your property needs and how the system will be laid out.

How the system moves water off your property

The crew begins by mapping the areas where water collects and identifying the natural flow paths across your lot. Trenches are cut to the depth and grade needed to carry water away from your foundation, driveway, and planted areas. Perforated pipe, solid pipe, or a combination of both is installed depending on whether the goal is collection, transport, or both.


Once the system is in place, runoff that used to flood your yard is intercepted and routed to a safe discharge point. You see dry ground where water used to sit, no more erosion cutting through your lawn, and a foundation that stays protected during storms. Drainage systems are designed to protect foundations, driveways, and landscaping over the long term.


The installation also accounts for future maintenance access, so the system can be inspected and cleared without excavation. Filter fabric and gravel bedding prevent soil from clogging the pipes. If your property has steep grades or multiple drainage issues, the system integrates with retaining walls and regrading work to address everything at once.

Homeowners usually want to know how the system will fit their property, what the work involves, and how long it takes before they see results.

Questions people ask before they call

What does a storm water drainage system actually do?

It collects runoff from rain and snowmelt and moves it away from your foundation, driveway, and landscaping through underground pipes and graded channels. You stop seeing standing water and erosion in areas where drainage was poor.

How do you decide where the drainage pipes go?

The layout is based on your property's slope, soil type, and where water naturally flows or pools. Stanley Excavation & Grading evaluates the site and designs a system that works with the existing grade and directs water to a safe outlet.

How long does installation take?

Most residential drainage systems are installed in one to three days depending on the size of the area and complexity of the layout. You can use your yard again as soon as the trenches are backfilled and compacted.

What happens if the system gets clogged?

Properly installed systems include filter fabric and gravel to prevent soil infiltration, and access points are placed for cleaning if needed. Routine inspection keeps the pipes clear and the system working as designed.

Can drainage be added to a property that already has grading issues?

Yes, drainage installation is often combined with regrading to correct slopes and ensure water moves in the right direction. The two services work together to address both surface flow and subsurface runoff.

If water is pooling on your property or you see erosion forming after every storm, a drainage system can stop the damage before it reaches your foundation or hardscaping. Contact Stanley Excavation & Grading to request a drainage evaluation and get a system designed for your site.
