Woburn's neighborhood names are informal and overlap — Four Corners blends into what locals also call West Woburn, and the homes here share the same mid-century character.

Homes and plumbing in Four Corners

  • Mid-century ranches, capes, and colonials. Much of the area was built in the mid-1900s, when copper water lines were standard. Aging copper can develop pinhole leaks, and one pinhole often means the line is thinning elsewhere.
  • Basement floors are slabs. Water and drain lines often run under the basement floor. A leak there is a slab leak even though the house has a basement.
  • Older drains. Some homes still have cast iron drains under the basement slab. Cast iron rusts from the inside and can crack after decades of use.
  • Additions on slabs. Later additions and garages are commonly built on their own slabs, with pipes running underneath.

Common slab leak problems in Four Corners

  • A higher bill with no change in how much water the household uses.
  • Cracks newly appearing in floors or walls.
  • Warm spots on the floor, often a hot water line leak.
  • Damp carpet, hardwood that cups, or loose tiles near the leak.
  • Running water sounds with everything switched off.
  • Musty smells or mildew near baseboards or in the basement.
  • Pressure down at several fixtures at once.

How detection works

Four Corners homes are mostly mid-century with copper lines under basement floors, so detection usually starts on the supply side: meter and pressure tests, then acoustic listening and thermal imaging to find the pinhole. Drains under the floor get a camera inspection and hydrostatic test. Our slab leak detection page explains each test.

Slab leak FAQs for Four Corners

Is Four Corners the same as West Woburn?

The names overlap. Locals use Four Corners for the Lexington Street and Cambridge Road area, and West Woburn for the wider western side of the city. Either way, if you are in Woburn, you are covered — call (781) 483-8802 and ask.

How do I know if the leak is a water line or a drain?

Check the meter with everything off. If it moves, the leak is likely a supply line, often the mid-century copper under the basement floor. If it is still but you smell sewage or see damp spots near drains, the drain line is the likely cause.

What should I do first if I think I have a slab leak?

First, shut off the main water valve if water is visible, usually in the basement near the meter. If the floor feels warm, turn off the water heater as well. Then call (781) 483-8802 for help.
