Clay-loam soil at the base of the foothills. Terrain is slightly more varied than the plains cities, with some hillier lots near Coal Creek and the western edges of town. Slopes may need different head types and zone configurations.
Good to know: Louisville has the highest median home value in the area at ~$835,000. Homeowners here invest in their properties. The Marshall Fire rebuilds mean many homes now have brand new irrigation systems with smart controllers.
Louisville homeowners care about their properties. With median home values over $800K, a well-maintained sprinkler system protects a serious investment. We understand Louisville's hillier terrain near the foothills and adjust zone layouts accordingly.
A sprinkler blowout costs $95 for up to 8 zones (+$7 per additional zone). For Louisville and the rest of the Front Range, the window is late September through October, before the first hard freeze.
Louisville splits into two very different jobs. The Marshall Fire rebuilds have new systems on smart controllers, and those need the controller wintered properly along with the lines cleared. Putting a smart controller into standby is not the same as switching a mechanical timer off. The rest of Louisville is long-established, with mature trees whose roots run alongside the irrigation lines, so a freeze crack there is a harder repair to dig out.
