Plumbing leaks and foundations in Leon Valley

Water under the slab

Many Leon Valley homes are 40 to 60 years old, often with original cast-iron drain lines under the slab. A cracked drain or supply line can soak the soil under one area, causing it to swell or wash out.

Why test first

If a leak is causing the movement, lifting the foundation without fixing the leak can mean the problem comes back. A licensed plumber can do a pressure test on the supply and drain lines. Some foundation companies recommend this before repairs.

Insurance angle

Normal settling is usually not covered by homeowners insurance, but damage from a sudden plumbing leak sometimes is. If a leak is found, ask your insurer before work starts.
