Henderson is unincorporated Adams County along the South Platte River north of Thornton, at about 5,030 feet, the lowest ground in this part of the county. A post office has operated here since 1894, and the area was once called Henderson Island, which tells you how the river treats it. Pieces have been annexed by Thornton, Brighton, and Commerce City, but the core is still county: 1970s and 1980s ranches on acre lots, some on wells and septic, and newer two-stories on the higher ground east of Riverdale Road. The May 30, 2024, hailstorm dropped hail larger than limes here.
This site connects Henderson homeowners by phone with an independent local water damage provider.
A Henderson house on a well and septic has two extra questions after a flood: whether the well head took surface water and whether the drain field is saturated. Neither is the cleanup crew's job, but both change what happens next in the house, and the person who answers the phone should hear about them.
A basement that took groundwater when the river and the water table came up together is a basement flooding cleanup. A ranch on a crawl space with a supply line that froze under the floor is a frozen pipe cleanup. A hail-bruised roof that leaked into the attic is roof leak and hail water damage.
The county's Riverdale Regional Park and Fairgrounds sits on the river bottom here, connected to the South Platte River Trail, and the same bottomland runs under the older Henderson lots. Rebuild permits for an unincorporated Henderson address are filed with Adams County, not any of the three cities that surround it.
Call (720) 735-3725 and say what you found. An independent local water damage provider serving Henderson picks it up from there.
Water pumped out of a finished or unfinished Thornton basement, then the bottom of every wall and the slab metered to see what stayed wet.
Standing water pulled off carpet, tile, wood, and concrete on any floor of the house, with the first moisture readings taken the same visit.
Air movers and dehumidifiers set from daily readings until subfloor, studs, and drywall reach their dry target in a dry-climate house.
Cleanup after a supply line froze in a garage wall, crawl space, or north-facing wall during an arctic night and split when it thawed.
A failed supply line, a cracked fitting, or an old galvanized run in a 1950s ranch let go, and the rooms it soaked get pumped out and dried.
The tank in the basement utility corner rusted through overnight, and the floor, framing, and stored boxes it soaked get dried out.
Wet attic insulation, ceilings, and walls dried after a hailstorm, a wind-torn shingle, or an ice dam let meltwater into the house.
A high Thornton Water bill, a warm patch on a slab floor, or a damp spot with no visible source tracked to the pipe behind it before walls open.
