I get this question all the time from homeowners across the Washington metro area:
“Bob, we’ve got standing water in the yard—is that something we need to fix right away? Or is it just normal?”
And like most good questions in home care, the answer is: it depends.
Some puddles are harmless. Others? They’re red flags for deeper problems that could end up costing thousands if ignored.
After 42 years helping folks across D.C., Maryland, and Northern Virginia, I’ve seen how confusing water issues can be. So in this article, I’m going to give you the full picture: – When standing water is normal and harmless – When it’s a problem – How we investigate it – What smart fixes look like – And a few real homeowner stories to show you how it plays out in the real world
Because when it comes to water, you want to get ahead of it—not chase it.
When Standing Water Is Not a Big Deal
Let’s start with the good news.
1. Temporary puddles after rain
If you’ve just had a solid D.C.-style thunderstorm and you’ve got a few puddles that disappear within a day, that’s normal.
Why? Because even healthy soil needs time to absorb water. In fact, some standing water means your system is doing what it’s supposed to—slowing and spreading the flow instead of letting it all rush away at once.
2. Low spots in your lawn (far from the house)
Got a shallow dip in the back corner of the yard? As long as it doesn’t hold water for more than a day or two, and it’s not affecting foot traffic, landscaping, or structures—you’re probably fine.
These can be graded out later or used for intentional drainage.
3. Rain gardens or designed collection areas
Some yards are designed to hold water temporarily—especially if you’ve got a dry well, rain garden, or bioswale. These areas are like nature’s sponge. As long as they’re working properly, they’re a good thing.
When Standing Water Is a Real Problem
Now, let’s talk about when those puddles are a warning sign.
1. It lasts more than 48 hours
If water hangs around for days after a storm, it’s not draining properly. That can: – Drown your grass and plants – Create mosquito breeding grounds – Lead to soil saturation (which we’ll talk about in a minute)
One client in Falls Church had a side yard that looked like a rice paddy after every storm. What started as a nuisance turned into a mold issue under their siding—and eventually a basement leak.
We fixed it with a combination of French drains and a simple grading correction. But they told me afterward, “We wish we’d called you two years ago.”
2. Water pools near your foundation
This is a big one. If water is pooling near your home’s foundation, it’s not a matter of if—it’s a matter of when it causes problems.
Water in the wrong place leads to: – Foundation cracks – Wet basements and crawl spaces – Mold and mildew – Structural shifting
One family in Silver Spring had a beautiful home, but water was pooling along the back wall. After a few years, they noticed musty smells and uneven flooring. We discovered the soil was oversaturated, and hydrostatic pressure was pushing water right through the foundation.
We installed a perimeter drain, redirected the downspouts, and added a dry well. The home dried out, the smells disappeared, and their next home appraisal went up $15,000.
3. It’s ruining your landscaping or hardscaping
Water doesn’t just sit still. It flows. And if it’s flowing through your flower beds or hardscape areas, it’s doing damage every time it rains.
Common signs include: – Washed-out mulch – Exposed roots – Sinking pavers or cracked patios
We helped a homeowner in Arlington who lost $4,000 in landscaping installs after a single summer storm. They didn’t know that their neighbor’s runoff was crossing their yard. A properly designed swale and collection basin solved the problem—and they’ve had zero plant loss since.
4. It’s in a high-traffic or functional area
Standing water near a walkway, driveway, or patio isn’t just inconvenient—it’s a hazard.
You’d be shocked how many homeowners we’ve worked with who slipped or tracked mud indoors week after week. One client in Alexandria had a toddler who slipped on a water-slicked flagstone path. That was their “enough is enough” moment.
5. You’re seeing multiple red flags
If you’ve got standing water and: – Overflowing gutters – Downspouts dumping near the house – Water in the basement – Sump pump that discharges right into the yard
…you’ve got a drainage system that’s failing—and it needs a pro.
What Causes Standing Water in the First Place?
There are usually multiple contributing factors, including: – Improper grading (yard slopes toward the house) – Clay soil that doesn’t absorb water quickly – Compacted soil from construction or foot traffic – High water tables in certain parts of the DMV – Short downspouts or sump pumps that discharge too close to the foundation – Lack of drainage pathways to move water downhill
Understanding the why is the key to solving the how.
What We Look For During a Drainage Evaluation
At AskBobCarr.com, when we do a drainage evaluation, we assess: – Where the water is coming from (roofs, neighbors, grade) – Where it’s pooling – Soil type and how fast it drains – How close the issue is to your foundation or living spaces – How it affects landscaping, usability, and safety
We don’t show up with a cookie-cutter solution. We design based on: – The age of the home – Your long-term plans – Local code requirements – Smart water management practices
And we explain it all in plain English.
Real Homeowner Stories
Case 1: “The Trampoline Pond” in Rockville A family called us about water that pooled under their kids’ trampoline. The yard was flat, the soil was dense, and runoff from uphill was collecting in one spot. We installed a simple French drain with an underground pipe to the back corner. The trampoline stayed dry, the lawn came back, and the kids could play again.
Case 2: Basement Wall Mystery in Vienna This homeowner noticed one basement wall staying damp, even though it hadn’t rained in days. We traced it to standing water from a nearby garden bed that sloped toward the house. We re-graded, moved the bed, and installed a gravel trench. Wall dried out, and the humidity levels dropped by 40%.
Case 3: HOA Trouble in Springfield A homeowner was getting letters from the HOA because standing water from her yard was spilling onto a shared sidewalk. She had no idea what to do. We worked within the HOA’s drainage easement, created a swale, and piped her downspouts farther downhill. The letters stopped, and she told us, “That was the first good night’s sleep I’ve had in a while.”

Bottom Line from Bob Carr
Not all puddles are a problem.
But when standing water lingers, spreads, damages landscaping, or sneaks toward your foundation? That’s not something to ignore.
