Henderson's slabs
Henderson sits on the southeast side of the Las Vegas Valley, next to the city of Las Vegas. Its older core dates from the middle of the last century. Most of the city, though, was built from the 1980s onward, in large planned communities with shared landscaping and associations.
Green Valley is among the earlier of those, built through the 1980s and 1990s. Anthem and Seven Hills followed, and newer neighborhoods fill the south and southwest. Single-story and two-story plans share the same basic construction: a slab with supply lines beneath it.
Copper is the typical supply line in the 1980s to 2000s homes, some of the earliest fall in a polybutylene era, and newer builds often have PEX. Your home may differ, and the technician confirms it.
What is under Henderson slabs, decade by decade
Homes from the 1970s and earlier tend to have copper that has often been repaired or rerouted already. Through the 1980s and 1990s, copper stays typical and a polybutylene era shows up in some homes. From the 2000s on, copper and PEX both appear.
None of that tells you what is under your floor. The technician confirms the material with a look at the entry point and the manifold. Boom-era home slab leaks sets the decades out in full.
The warm spot on the floor
A patch of floor that feels warm underfoot, especially in the morning or when no one has run hot water, is a classic sign of a hot line leaking under the slab. It may be small or may cover a room.
Note where it is, which way it spreads and whether it changes through the day. Then read warm spot on floor. Do not open the floor yourself.
Ground, grading and access
Parts of Henderson are flat and parts slope, and lots on slopes were graded and filled before building. Caliche is common, as it is across the Valley. Both affect how a crew opens the slab and where it prefers to reach a line.
Where the ground is hard or the leak is under tile or cabinets, a reroute may be easier than a spot repair. Where the leak is in an open hall, a spot repair is often the most direct option. The crew explains the trade-off before work starts.
The second leak
A second leak, on the same line or a nearby one, changes the conversation. A single leak is a repair. A second suggests the line may be wearing in more than one place.
That is when reroute and repipe come up. Repeat slab leaks covers what a second leak tells the crew.
Pools, drip lines and the first check
Henderson has a high share of homes with pools and drip-irrigated yards. Both can raise a bill and both can move the meter, so they come first in any leak check.
Switch the irrigation controller off, check the pool level over a day and read the meter. If it still moves, the loss is on the house side and the slab is a candidate. The crew does not repair pools or irrigation.
What to have ready when you call
Have the year the home was built, the community name, the room where you notice the sign and the meter readings if you took them. Mention earlier leaks and what was done.
If your community has a gate, have the code or the visitor process ready. If there is an association, check your documents about work on your property or call management.
What Henderson callers usually report
The most common first report from a Henderson planned community is a warm patch near a bathroom or in a hallway, often noticed barefoot in the morning. The next most common is a bill that has crept up over two or three months while the household did nothing differently.
A third group hears water at night. In a two-story Henderson plan, the sound can seem to come from a wall upstairs when the leak is actually in the line beneath the ground floor. The crew listens at several points before marking anything.
Associations, gates and scheduling
Many Henderson neighborhoods have an association and a gate. A leak crew needs to be on the visitor list, and some associations ask for notice before work that affects the exterior. Check your documents or call management, and give the crew the entry details.
If the work will open a floor, tell anyone sharing the home about the plan and the noise. Ask the crew how long each stage is expected to take, from locating through to the closed floor.
Older Henderson streets
Not all of Henderson is planned-community housing. The older streets near the center have smaller homes from the middle of the last century, where lines have often been reworked. A leak there tends to raise the same repair question as in older parts of Las Vegas: spot repair where the pipe is reachable, reroute where it is not.
A Henderson visit, step by step
The crew arrives, asks the year built and the community, and walks the house with you. They read the meter with everything off, then isolate the hot side from the cold side and test pressure on each.
With the line identified, they listen across the floor and use a thermal camera on hot lines. The spot is marked, the options are explained with prices, and nothing is opened until you agree.

Henderson slab leak questions
Do Green Valley homes have copper under the slab?
+
Many homes of that period do, though remodels and repairs vary. The technician identifies the material on site.
Can a Henderson home on a slope still have a reroute?
+
Often yes. The route depends on attic space and layout, and the crew explains it before work starts.
Do I need HOA notice?
+
Check your community documents and call management. The crew can tell you what they will be doing.
What is a polybutylene era?
+
A period when a plastic pipe called polybutylene was used in some homes. Many have been repiped since. The technician confirms what is in your home.
Is a second leak normal?
+
It is common in homes of this age. A second leak near the first can point to wear along that line, and that is when reroute comes up.
Can I call about Henderson at night or on a weekend?
+
Yes. The line is answered 24/7, including nights, weekends and holidays. If anything here is unclear for your place in Henderson, ask on the call.
Could a pool or irrigation line be the source in Henderson?
+
It could be. Shut off irrigation and pool fill lines and test the meter again before assuming the leak is under the floor. Mention that you are in Henderson so the person who answers can keep it in context.
Could a high water bill in Henderson have another cause?
+
It could. Seasonal watering and fixture leaks are common explanations. If the bill keeps rising and the meter moves while water is off, a hidden leak becomes more likely. It applies to Henderson in the same way it does elsewhere.
