Drain Cleaning FAQ
Can I unblock an outside drain myself?
This is the drain job with the best DIY odds, because exterior drains almost always block at the top with leaves and grit rather than somewhere buried.
Short answer
Often yes, because outside drains usually block at the top where you can reach. Lift the grate and clear out the leaves, silt and grit by hand or with a trowel, then look into the chamber below. If water drains away once the debris is gone, that was the whole problem and the job is twice-yearly maintenance from then on. If the chamber stays full, run a garden hose in hard and try a hand auger from the chamber toward the outfall. Stop if the blockage is more than a few feet along, if it smells of sewage rather than stagnant water, or if several outside drains are backed up together. Those point to the buried run or a shared line and need a camera to locate.
Clearing It, Step by Step
- Lift the grate. Most lift straight out; some are screwed. Expect it to be heavier and dirtier than it looks, and wear gloves.
- Scoop the chamber out by hand or with a trowel. Leaves, silt, grit, roof granules and the odd tennis ball. This alone resolves the majority of blocked yard and area drains.
- Flush with a garden hose at full pressure, aimed into the outlet rather than straight down. If the water runs away freely, you are done.
- If the chamber holds water, try a hand auger fed into the outlet pipe, or a pressure-washer sewer jetter kit if you have one; a short run of exterior pipe is exactly where those kits work.
- Put a leaf guard over the grate and clear it twice a year, once in late autumn and once in spring. That converts a recurring problem into a five-minute task.
When It Is Not the Grate
Three signals mean the blockage is in the buried run rather than the chamber, and they change who should be doing the work:
- Several exterior drains backed up at once. They share a line, and the shared line is the problem.
- It smells of sewage rather than stagnant water. Stormwater and foul drainage should be separate. Sewage smell at a yard drain suggests a cross-connection or a failing line nearby, and that is worth investigating properly.
- Water rising out of the drain rather than failing to enter it. Something downstream is full.
Roots are the usual cause in the buried run, because exterior drains are shallow and sit close to landscaping. Locating the blockage needs a camera, which is part of the scope on our drain cleaning page, and if the pipe has been displaced by roots it moves into pipe repair.
Why This Matters More in a Freeze-Thaw Climate
A blocked exterior drain in Northern Colorado is not just a puddle. Water that cannot get away pools against the foundation, soaks the backfill, and then freezes and expands through the winter, which is how you get foundation movement and water finding its way into a basement. A yard drain, window well or driveway trench that is slow in October is worth half an hour before the first hard freeze rather than in spring.
The same logic applies to the systems that keep water out of the basement once it is there. If you are already seeing moisture at a basement wall or floor drain, sump pump repair and battery backup is the companion job, and the seasonal drain schedule covers what else is worth doing before winter.
