Copper Replacement Option in New Castle
Some homeowners choose Type L copper for its long history and rigid feel. We solder with lead-free solder or use pressed fittings for faster installation. Copper costs more than PEX and takes a little longer to install. We help you weigh the options for your budget and water conditions.

PEX Pipe Installation in New Castle, DE
PEX (cross-linked polyethylene) is a popular choice for polybutylene replacement due to its flexibility, durability, and resistance to corrosion and freezing. It is also more cost-effective than copper and easier to install, reducing labor time. Our team in New Castle, DE specializes in expert PEX piping installation, providing a reliable and long-lasting plumbing solution for your home.
Polybutylene to PEX Transition in New Castle, DE
Transitioning from polybutylene to PEX is a popular and cost-effective solution for many homeowners in New Castle, DE. We utilize specialized transition fittings and techniques to seamlessly connect your existing main water line to the new PEX system. This ensures a watertight and code-compliant connection, providing a complete upgrade to a modern, durable plumbing material throughout your home's interior. This transition offers the benefits of PEX without the need for extensive excavation or disruption to your main service line.
Copper Pipe Replacement in New Castle
For homeowners who prefer a traditional, sturdy solution, copper piping is an excellent alternative to polybutylene. Copper is very durable, resistant to bacteria growth, and has a proven track record of longevity. While typically a higher investment than PEX, copper offers superior strength and reliability. We provide precise copper pipe installation services across New Castle.
Polybutylene Replacement Costs in New Castle, DE
Replacing polybutylene with PEX in an average home often costs $5,000 to $12,000, depending on size and bathrooms. Copper systems typically cost more. Adding a yard service line replacement often adds $1,500 to $4,000. Compared to repairing water damage from a burst, a planned replacement is usually the better investment.
Full Home Repiping with PEX in New Castle
When a home with polybutylene pipes sits on a slab foundation, repiping becomes a more complex process. Our team specializes in full home repiping using PEX (cross-linked polyethylene), a flexible, durable, and corrosion-resistant material. PEX is an excellent choice for Delaware homes, as it resists freezing better than rigid pipes and expands to accommodate temperature changes. We carefully plan the repipe to minimize disruption, often running new lines through attics or existing wall cavities, ensuring a complete and long-lasting upgrade for your entire plumbing system.
