- ▸Wall repair: Drywall patching/painting can add $1,000–$3,000 if not in scope.
Why replace polybutylene
The clock is ticking
Polybutylene piping was installed in millions of U.S. homes between 1978 and 1996, including thousands across Middletown, Bear, and Newark. Chlorinated municipal water reacts with the plastic from the inside out — and the failure point is invisible until a pipe bursts behind a wall.
A single overnight burst can cause $20,000+ in water damage. A planned repipe is almost always cheaper than the emergency you're trying to avoid.
FAQ
Common questions
How much does it cost to replace polybutylene pipes in Delaware?
Most Delaware homes fall between $4,000 and $15,000 for a full polybutylene repipe. The biggest cost drivers are total square footage, fixture count, foundation type (slab vs. crawlspace), and whether you choose PEX, CPVC, or copper. Our calculator gives you a personalized range in under 60 seconds.
Is replacement covered by insurance?
Polybutylene is generally not covered as a planned upgrade, but resulting water damage from a PB failure often is. We help document inspections so homeowners can pursue claims when applicable.
How long does a polybutylene repipe take?
A typical single-story home takes 2–4 days. Multi-story or slab-foundation homes can take 4–7 days. We work room-by-room to keep at least one bathroom usable throughout.
CPVC, PEX, or copper — which should I choose?
We recommend CPVC for most Delaware repipes: it's chlorine-resistant, rigid, and a proven long-term performer. PEX is a flexible alternative with fewer joints. Copper lasts longest and adds resale value but costs 3–5x more in materials and labor.
