Tri-Cities Home Improvements works regularly in the Highlands neighborhood of Kennewick where homes sit on slopes above the Columbia River. Older properties here often have galvanized or early copper lines that corrode faster from the mineral content in Benton County water. Winter freezes along the river corridor crack those lines while summer heat bakes the soil and shifts foundations slightly each year.
Access to many Highlands homes runs along narrow driveways and tight side yards that back up to the Columbia River bluffs. Our crews know which streets allow truck entry and which require smaller equipment to reach cleanouts without tearing up landscaping. We handle everything from slab leaks to sewer line repairs that come up after the cold snaps common in this part of the Columbia Basin.

Plumber in Highlands — Local Notes
- •Many Highlands homes built in the 1970s and 1980s still have original galvanized supply lines that restrict flow and fail during freezes.
- •Sloped lots and shallow crawlspaces expose pipes to wind off the Columbia River making insulation and heat tape common requests each November.
- •Hard water scale builds quickly on fixtures because Highlands sits on the same aquifer that serves most of Benton County.
- •Dry summers crack clay soil around foundations allowing roots to reach sewer lines faster than in flatter Kennewick neighborhoods.
