Local knowledge / 02

What Granite Falls homes
throw at us.

This is the housing stock we know best — because it's ours.

01

Well and septic country

A big share of homes here run on wells and septic. We work on pressure tanks, well-fed fixtures, and keep drain work septic-safe.

02

Foothills freeze-thaw

Cold snaps hit the foothills harder. Exposed crawlspace lines and hose bibs freeze — we insulate, add heat tape, and fit frost-free bibs before winter does its thing.

03

Farmhouses next to new plats

A 1920s farmhouse with galvanized pipe can sit a quarter mile from a 2020s build with PEX. We're fluent in both.

04

Off the gas grid

Beyond the city's natural gas reach, propane rules. Tanks, regulators, appliance hookups — permitted and pressure-tested.
