Hi, I’m Bob Carr. Over the years, I’ve seen homeowners ignore what looks like a “little washout” on the edge of their lawn — only to end up with major damage months later.
Erosion doesn’t go away. It gets worse, faster, and more expensive every season you wait.
It might look like a small bare patch now. But if water keeps running through that zone, you could be looking at lost landscaping, exposed pipes, foundation damage, and even property code violations.
Let me show you what erosion really is, how it starts, where it spreads, and why fixing it now always costs less than fixing it later.
What Erosion Actually Is
Erosion is when water wears away the surface of your yard, stripping off topsoil and carving channels into the ground.
Common erosion symptoms: – Bare patches where grass won’t grow – Exposed roots or underground pipes – Mulch that washes out after every storm – Fence posts or patio edges shifting over time – Silt building up on walkways or drains
One client in Bowie said, “We thought the mulch was just blowing away in storms.” But the runoff from their uphill neighbor had been carving a groove behind the shrubs for over a year. By the time we were called in, the fence posts were tipping and the AC pad had cracked. All from “just a little washout.”
Where Erosion Starts (and Spreads)
Erosion usually starts small — at a gutter downspout, the edge of a hill, or a low point where water naturally collects.
But it spreads fast: – From turf into flower beds – From mulch beds into patios or pathways – From side yards toward your home’s foundation – From one season into the next, getting deeper every time
We call it the creep. It doesn’t happen overnight. But it never stops unless you stop it.
Real Homeowner Example: Severna Park, MD
A homeowner had a small erosion trench forming behind their garage. It was maybe 3 inches deep. They said, “We’ll deal with it in spring.”
Spring came. The trench was now 9 inches deep, exposing the concrete footer of the garage pad. Water was pooling at the base.
Our fix: – Installed a swale to redirect surface water – Rebuilt the slope with fresh topsoil and jute mat – Seeded and reinforced with deep-root native grass
Had they waited another year? The pad would have cracked, requiring demo and pour. The delay saved them over $12,000.
Why Waiting Costs You More
- Deeper Damage = Bigger Fixes
A shallow trench is easy to fill and reroute. A deep cut might require excavation, regrading, and wall reinforcement. - Washed Away Soil = Harder Restoration
You can’t just throw grass seed on a gully. You have to rebuild the root zone, reestablish grading, and stabilize the surface. - Hidden Erosion = Infrastructure Risk
We’ve seen erosion expose gas lines, crack sewer pipes, and undermine patios. These aren’t just cosmetic issues — they’re real hazards. - Foundation Impact = Big Money
When erosion shifts water toward your house, hydrostatic pressure builds. That leads to leaks, basement mold, and costly repairs. - Permitting & Code Issues
In many counties, serious erosion near property lines or stormwater easements must be repaired by licensed contractors with permits.
The AskBobCarr.com Fix Strategy
Here’s what we do when we diagnose erosion:
- Full Property Walkthrough
We trace water flow, slope, and discharge. We walk the yard in dry and wet conditions to understand what’s happening. - Identify Source & Exit
We find out where water is entering the erosion path — and where it’s trying to leave. - Choose the Right Fix Type: – Swales – French drains – Retaining edging – Dry creek beds – Geo-mesh erosion matting – Native plant restoration
- Build for Long-Term Performance
We fix the grade. Reinforce with real materials. And install systems that disappear into your landscape.
One job in Millersville involved a downhill backyard that eroded a full foot near the fence. We built a natural-looking rock swale, added native plants, and reset the grade — the homeowner said it looked better and stayed dry for the first time in years.
Real Homeowner Story: Annapolis, MD
A home on a sloped lot was losing its lawn near the water-facing edge. Over time, the bank dropped by 2 feet, exposing tree roots and threatening their patio.
We installed: – A natural stone retaining wall – Native plantings with deep roots – A catch basin and micro-swale system
Before: They couldn’t let their kids play near the edge, and they feared losing their patio in the next big storm.
After: Their lawn is stable, their view is safe, and they turned the edge into a beautiful feature garden.
FAQs About Erosion
Q: Can’t I just fill the eroded area with more dirt?
A: You can, but if you don’t fix the water source, the problem will return — and often worse.
Q: Is erosion really dangerous to foundations?
A: Absolutely. It removes soil support, exposes footers, and channels water toward the structure.
Q: How long does it take to fix?
A: Most residential fixes take 1–3 days. Larger rebuilds can take a week.
Q: What does it cost?
A: Small erosion fixes start around $2,500. Complex restorations with walls or drains range $7,000 to $15,000+.
Q: What if it’s a shared issue with a neighbor?
A: We’ll work with both parties to design a solution that benefits both properties and complies with local codes.
Q: Can I do it myself?
A: Small fixes are possible, but erosion is usually deeper than it looks. We’ve been called in to fix a lot of well-meaning DIYs gone wrong. Always start with a walkthrough.
Erosion Red Flags Checklist
✅ Bare or thinning grass on slopes
✅ Mulch that won’t stay put after storms
✅ Soil or silt collecting near walkways
✅ Downspouts emptying into low spots
✅ Fence lines or retaining walls that lean
✅ Roots or pipes exposed near the surface
✅ Patio edges or steps sinking

Final Thoughts From Bob
Erosion is slow — until it isn’t. One big storm can undo a season of growth. And one more season of waiting can turn a $2,000 fix into a $12,000 repair.
The fix doesn’t have to be massive. But it has to be right. We’ve helped hundreds of Maryland homeowners stop erosion early — and save thousands in the process.
Let us walk the property, trace the water, and build a fix that works with your yard — not against it.
