Erosion control, drainage, and washout repair for properties throughout Quechee, Woodstock, Windsor, and Hartland, areas that see real storm and river-related damage each season. Thompson Site Services responds quickly to washouts and builds long-term drainage solutions so the same problem doesn't come back after the next storm.
Understanding Erosion & Washout Repair
Vermont and New Hampshire have seen a number of serious flooding and storm events in recent years, and hilly terrain combined with heavy rainfall can overwhelm drainage systems that weren't built for today's storm intensity. The result is washed-out driveways, undermined foundations, failing retaining walls, and new channels cut across properties that never used to have a drainage problem.
Fixing erosion properly means addressing the cause, not just the symptom. That usually means regrading, adding or upgrading drainage, or building a retaining structure suited to the site, rather than trucking in fill that washes out again in the next storm. Larger projects that disturb an acre or more of land in Vermont also require a stormwater construction permit, and work near a stream may need additional review.
How We Get It Done
Site Assessment
We evaluate the source of the erosion or washout, including slope, drainage patterns and water flow.
Plan the Fix
We design a solution suited to the site, whether that's grading, drainage installation, retaining walls or slope stabilization.
Stabilize & Repair
Our crews regrade, install drainage, or build retaining structures to correct the underlying problem.
Restore the Site
Disturbed areas are restored with appropriate material to prevent future erosion.
Follow-Up as Needed
Severe storm damage sometimes calls for a return visit once conditions settle to confirm the fix is holding.

Frequently Asked Questions
Why does the Upper Valley see so much erosion and washout damage?
Vermont and New Hampshire have seen a number of major flooding events in recent years, and hilly terrain combined with heavy rainfall can overwhelm drainage that wasn't built for today's storm intensity.
Do I need a permit for erosion control work?
Larger projects that disturb an acre or more of land in Vermont require a stormwater construction permit, and work near streams may need additional review. We can help identify what applies to your project.
Can you respond quickly after a storm?
Yes. Washout and storm damage is one of our emergency response priorities, and we aim to get to affected properties as quickly as possible to prevent the damage from getting worse.
Will fixing the erosion actually stop it from happening again?
Our goal is always to address the underlying cause, whether that's grading, drainage or water flow, rather than a temporary patch that fails in the next storm.
