Where the Water Goes Matters Most
Clean gutters collect the water. Downspouts bring it down. But if the downspout ends a foot from your foundation, all that collected water lands in the worst possible spot. Bethesda's clay-heavy soil holds water against basement walls instead of draining away. That is how a working gutter system still leaves you with a damp basement: the gutters did their job, and the last two feet undid it.
Drainage solutions fix the last two feet. Extensions, splash blocks, and regrading carry roof water four, six, ten feet out — past the foundation backfill and into the yard where it can soak in harmlessly.
What We Install
Hinged extensions. Rigid extensions that flip up for mowing and flip down for rain. The workhorse solution — simple, tough, and easy to live with.
Fixed extensions. For downspouts along beds and borders where nothing needs to move. Set once, done.
Splash blocks. Simple concrete or plastic blocks that spread the discharge and stop it from digging a trench at the foundation.
Grading fixes. Sometimes the ground itself slopes toward the house. We regrade the soil along the foundation so surface water runs away, not toward.
The Basement Connection
If your basement gets damp after heavy rain, check your downspouts before you call a waterproofing company. We see it constantly: thousands of dollars quoted for interior drains when the real problem is four downspouts ending at the foundation. Extensions are the highest-value water work we do, dollar for dollar. Our guide on gutters and basement water walks through the full picture.
A Word on Buried Drains
Some companies push buried drain pipe for every downspout. Sometimes it is right — a downspout with nowhere to daylight above ground, for example. But buried drains clog with leaves and roots, freeze in winter, and cost real money to dig up and fix. We recommend them only when surface solutions genuinely will not work, and we will tell you why if that is your situation.
How It Works
Step 1 — Free visit. We trace every downspout, watch where water lands, and check grading around the foundation.
Step 2 — Written estimate. Extensions, blocks, grading — itemized. Every home is different — contact us for a free written estimate.
Step 3 — Install. Most drainage jobs finish in a few hours.
Step 4 — Rain test. We run water through the system and confirm it lands well away from the house.
The Drainage Walk-Through: What We Check
Every drainage visit starts the same way: we walk every downspout from gutter to ground during or right after rain if possible, because water tells the truth. Here's what we're looking at. Exit points: where does each downspout actually discharge? A foot from the foundation is a fail; four to six feet out is the minimum pass. Extensions: present, connected, and pointing the right way — or knocked loose by the mower three summers ago. Splash blocks: still under the discharge, or migrated across the yard. Grading: does the ground slope away from the house for the first several feet, or has it settled into a moat? Collection points: low spots where multiple downspouts' water converges — these need a plan, not just an extension.
We also look at what's around the discharge: mulch beds that wash out every storm, walkways that ice over in winter, neighbor's property lines (your water is your responsibility), and wells or septic drain fields on larger lots. Drainage isn't just about moving water away from your foundation — it's about putting it somewhere it can't cause a different problem.
The walk-through ends with a simple sketch: every downspout, where its water goes now, and where it should go. Most drainage plans are a mix of extensions, re-aimed discharge, and small grading fixes. Boring work, honestly — but it's the work that keeps basements dry.
