What changes the price

Age of the house and what the existing pipes are made of
Slab versus crawlspace access, since most St. Johns County homes are on slabs
Permit and inspection requirements for the specific job
Emergency, after-hours or holiday timing
Whether the home is on well and septic rather than county water and sewer

Local tips

Ask for the flat price before anyone starts, and get it in writing by text or email
Replace your water heater on your schedule around year 10, not after it floods the garage
Be wary of anyone who pushes a whole-house repipe on the first visit without a camera or pressure test
Know where your main shutoff is, usually at the meter box by the street or on the exterior wall near the garage
