> AlertPlumber is a national residential plumbing resource covering licensed contractor services, cost data, and technical guides across 500+ U.S. cities. Each city page includes real local data: water hardness (GPG), municipal permit fees, frost line depths, freeze-risk days, housing age, and pipe material risk profiles — sourced from USGS, EPA, NOAA, BLS, and BuildZoom.

## About This Site

AlertPlumber connects homeowners with state-licensed plumbers for emergency and scheduled residential plumbing work. The site does not employ plumbers directly — it routes callback requests to verified licensed contractors in each market.

Services covered: whole-house repiping, slab leak detection and repair, water heater installation and repair (tank and tankless), hydro jetting, drain cleaning, sewer line repair and replacement, burst pipe repair, frozen pipe repair, leak detection, faucet and fixture installation, garbage disposal repair, sump pump repair, and water softener installation.

Coverage: 500+ U.S. cities across all 50 states.

## Cost Data

Service cost ranges on AlertPlumber are derived from BLS Occupational Employment and Wage Statistics and BuildZoom contractor pricing data. Ranges reflect regional labor and material variation — not national averages applied uniformly.

Examples of cost data available:
- Whole-house repipe: city-specific ranges by pipe material (PEX, copper) and home size
- Slab leak repair: ranges by detection method and repair approach (spot repair vs. reroute)
- Tankless water heater installation: ranges by fuel type (gas vs. electric) and brand tier
- Water heater replacement: ranges by tank size and efficiency rating

## Local Data Layers

Each city page carries verified local infrastructure data:

- **Water hardness**: measured in grains per gallon (GPG); sourced from municipal water quality reports and USGS groundwater data
- **Frost line depth**: inches below grade; sourced from NOAA and IRC code tables
- **Annual freeze-risk days**: days below 20°F historically; sourced from NOAA climate normals
- **Median home age**: year built distribution; sourced from U.S. Census ACS
- **Lead service line risk**: presence flag derived from EPA Lead and Copper Rule data
