Hi, I’m Bob Carr. I’ve been walking Maryland properties for decades — and nothing frustrates me more than seeing good people spend thousands on drainage systems that either don’t work or were never needed in the first place.
You deserve the truth before you invest in any drainage solution.
Let me walk you through the most overpriced drainage fixes I see in Maryland, and show you what we recommend instead — based on field-tested results, not just a fancy estimate.
1. Massive French Drains Where a Gutter Extension Would’ve Done It
Price tag: $7,000–$12,000
Real solution cost: $1,200–$2,500
The red flag: When the main water problem is coming from one or two downspouts.
What we see: A full-yard French drain system installed when all the water was caused by a single downspout dumping next to the house.
Better fix: Extend the downspout 30 feet underground, slope it properly, and let it discharge into a pop-up or daylight outlet. Done right, this often solves the core issue — no trench, no overkill.
Example: In Crofton, a family paid over $8,000 for a drainage network that didn’t help. The real culprit? One clogged downspout near their back patio. We cleared it, added a 20-ft extension underground, and the yard dried up in 48 hours.
2. Pipe Systems Installed in Clay With No Soil Prep
Price tag: $6,000–$15,000
Real value delivered: 20–30% performance
The red flag: Contractors installing drains without checking the soil.
Why it fails: If the soil doesn’t absorb water (clay-heavy or compacted), those drains can’t disperse it. You’ve just moved the water underground — where it still sits.
Better fix: Regrade the yard, amend the soil, and redirect surface water before installing any pipe.
Real-life example: A yard in Bowie had 3 drains but still flooded. We rebuilt the top 8” of soil and cut a swale for overflow. No more standing water — and no new pipes needed.
3. Decorative Swales That Look Great But Don’t Move Water
Price tag: $3,000–$7,000
Effectiveness: Mostly aesthetic
The red flag: Gravel-filled trenches with no slope or destination.
Why it fails: Looks good on paper, but water either skips over the swale or gets trapped because the layout wasn’t tested.
Better fix: Always check the grade. Use swales where gravity helps — and tie them into a functioning outlet, like a dry well or vegetated buffer.
4. Crawl Space Encapsulation Without Exterior Drainage Correction
Price tag: $12,000–$30,000
Real fix missed: The water source
The red flag: Contractors selling encapsulation without even walking the exterior grade.
Why it fails: If water still flows toward your home, all that plastic and insulation is just a band-aid. You’re sealing moisture inside instead of keeping it out.
Better fix: Fix the slope, extend your downspouts, and redirect water before sealing your crawl space.
Case example: In Annapolis, we pulled back a $20K encapsulation and found active puddles underneath. No outside work had been done. We regraded the slope, tied downspouts into buried lines, and gave the crawl real protection.
5. “One-Size-Fits-All” Drain Systems That Ignore the Yard’s Layout
Price tag: $10,000–$20,000+
What’s missing: A custom plan
The red flag: Same pitch, same system, every time.
Why it fails: Drainage isn’t one-size-fits-all. Your yard has its own slope, soil, runoff path, and history.
Better fix: Start with a walk. Read the water. Design a system for your yard — not a preset bundle.
Real Homeowner Story: Davidsonville, MD
A homeowner had flooding around their detached garage and paid $14,000 for a big-name company to fix it. Two years later — the water was back.
What we found: – Pipes installed level — no slope – No outlet – Grade still sloped toward the garage
What we did: – Sloped all pipes properly (minimum 2%) – Regraded away from the building – Built a swale and dry well system
Result: Flooding stopped. And the homeowners got back $10,000 worth of peace of mind.
Their words: “We assumed the first system didn’t work because of the rain. Turns out, it didn’t work because it was never designed to.”
Bob Carr’s Drainage Buyer’s Guide
Here’s what to ask before you sign a drainage estimate:
✅ Have they walked the entire property and tracked the water?
✅ Did they test your soil for compaction or clay?
✅ Can they explain the root cause before offering the fix?
✅ Is there a visible outlet for the system?
✅ Are they reusing or repairing failed systems — or starting clean?
✅ Did they talk about slope, surface water, and grading?
✅ Will the system handle heavy Maryland rain (1–2” storms)?
✅ Do you understand where the water is going after it leaves the pipe?
Why this matters: Every “yes” means they’re planning a fix based on your yard — not just selling you equipment.
