Downspout & Drainage Work in Salem, Keizer and the Mid-Willamette Valley
Perfect gutters that dump water at the base of the wall are not doing their job. An inch of rain on a 1,500 square foot roof is roughly 900 gallons, and in a Salem winter storm all of it exits through three or four downspouts. Where that water lands decides whether your crawl space stays dry and your foundation stays put.
Underground downspout lines run $150–$350 per downspout — call (503) 555-0142 for a number on your address.
The Last Six Feet Are the Ones That Matter
Soil in the Willamette Valley carries a lot of clay, which swells when wet and shrinks when it dries. Pour hundreds of gallons into it against a foundation wall every storm, all winter, and that cycle works away at concrete and mortar. Crawl spaces stay damp, cold joints weep, and mould follows. None of it happens quickly, which is exactly why it gets ignored — the damage from a bad discharge point shows up years after the cause. Four feet from the wall is the usual minimum, six is better, and on a lot that slopes toward the house you need a buried line.
What We Do With Roof Water
Downspout Extensions
Matching extensions clipped to the existing elbow, or hinged and roll-out versions on tight side yards where a fixed extension gets knocked loose by the mower.
Re-Routing Downspouts
Moving an outlet to a better discharge point — away from a walkway, a doorway or the low corner of the lot where water already collects.
Buried Drain Lines
Solid PVC trenched from the downspout to a daylight point or a dry well. The proper fix on a flat lot, and the one that actually keeps water off the foundation.
Pop-Up Emitters & Catch Basins
A bubbler at the end of a buried run lets water surface well clear of the house; a catch basin collects surface water where the yard sheds toward the wall.
Clearing Blocked Lines
Silt settles in buried pipe over years and plugs it, usually at a bend. We snake and flush the run, and camera-check it when a blockage keeps coming back.
Downspout & Drainage Work Prices in Salem, Oregon
Drainage work is quoted after we have seen where the water goes now and where it needs to go instead. These are the ranges we quote most often.
| Work | Priced | Typical range |
|---|---|---|
| Downspout extension, fitted and secured | each | $45 – $120 |
| Hinged or roll-out extension | each | $60 – $140 |
| Re-route a downspout to a better outlet | each | $95 – $250 |
| Underground downspout line, complete | per downspout | $150 – $350 |
| Buried line where trenching is longer than usual | per linear foot | $15 – $35 |
| Pop-up emitter at the end of a buried run | each | $30 – $85 |
| Catch basin | each | $60 – $180 |
| Dry well, gravel or plastic tank | each | $300 – $900 |
| Snake and flush an existing buried line | per line | $150 – $400 |
| Camera inspection of a repeat blockage | per line | $150 – $300 |
Every drainage job starts with a look at the whole system: if the gutter above the problem downspout is undersized or blocked, we will tell you, because moving the discharge point will not fix a trough that overflows.
What moves the price up or down
- Trench length and what is in the way — a driveway, a patio or mature roots all add labour.
- Soil: our clay digs slower than sandy ground and needs a proper gravel bed.
- Where the water can legally and sensibly go — daylight at a slope, a dry well, or a municipal connection.
- Whether an existing buried line can be reused or has to be replaced.
These are the ranges we quote most often, based on published 2026 cost data for Salem and the Portland metro and on our own jobs. They are estimates, not a quote — every price is confirmed in writing after we have seen the property, and it does not change afterwards unless you ask for extra work.
