Replace Old Pipes and Restore Full System Function
DNI Heating and Air provides complete re-piping services for homes and businesses in Boulder, Colorado to replace old or damaged plumbing systems.
When your plumbing system is old enough that leaks, low pressure, and water quality issues have become routine, individual repairs stop being a long-term solution. Galvanized pipes corrode from the inside, polybutylene pipes become brittle and crack, and aging copper can develop pinhole leaks that multiply over time. Re-piping replaces the entire system or major sections of it, which restores water quality, improves pressure, and eliminates the cycle of repeated repairs that never fully resolve the underlying problem in your Boulder property.
>DNI Heating and Air performs full re-piping services in Boulder from start to finish, replacing old or damaged pipes with modern materials that resist corrosion and provide reliable performance. The process includes removing the old piping, installing new lines throughout your home or building, securing all connections, and testing the system for leaks and proper flow. Re-piping improves water quality, restores water pressure to all fixtures, and increases energy efficiency by reducing heat loss in hot water lines.
If your plumbing system is outdated and causing ongoing problems in Boulder, reach out to discuss re-piping options and schedule an assessment of your current system.
New Pipes Eliminate Corrosion and Restore Consistent Flow
Re-piping in Boulder involves accessing the existing plumbing system, removing old pipes, and installing new lines that run to all fixtures, appliances, and water-using areas in your property. The new piping is typically made from copper or PEX, both of which resist corrosion and provide long-term reliability. All connections are secured with approved fittings, and the system is pressure-tested to confirm there are no leaks before walls are closed and finishes are restored.
Once re-piping is complete, you will notice that water pressure is strong and consistent at every faucet and shower, water runs clear without rust or sediment, and there are no leaks dripping behind walls or under floors. Hot water arrives faster because the new pipes retain heat better, and your water heater operates more efficiently without the buildup and blockages that often occur in old corroded lines.
Re-piping requires access to walls, ceilings, or floors where the old pipes are located, which means some drywall or surface materials may need to be opened and later repaired. The scope of the work depends on the layout of your plumbing system and whether the entire system or only certain sections need replacement. The project is planned to minimize disruption, and water service is restored as quickly as possible during the installation process.

You Probably Want to Know What This Project Involves
Re-piping is a major project, and homeowners often have questions about how long it will take, what kind of disruption to expect, and whether the entire system needs to be replaced. The answers depend on the condition of your current plumbing and the size of your property.
How do I know if my property needs re-piping?
You should consider re-piping if you experience frequent leaks, low water pressure throughout the property, discolored or rusty water, or if your home has old galvanized or polybutylene pipes. These symptoms indicate that the plumbing system has reached the end of its useful life.
What type of pipe is used during re-piping?
We typically use copper or PEX piping, both of which are durable, resist corrosion, and meet Boulder building codes. The choice depends on your property layout, budget, and specific system requirements.
How long does a re-piping project take?
Most residential re-piping projects are completed within three to seven days, depending on the size of the property and the complexity of the plumbing layout. We work efficiently to restore water service and minimize the time your home is affected.
Will you need to open walls and ceilings?
Yes, accessing the old pipes typically requires opening walls, ceilings, or floors where the plumbing runs. We make access openings as small as possible and coordinate with you to repair and restore surfaces after the new pipes are installed and tested in Boulder.
How does re-piping improve energy efficiency?
New pipes reduce heat loss in hot water lines, which means your water heater does not have to work as hard to maintain temperature. This lowers energy use and can reduce your monthly utility costs over time.
Re-piping is a comprehensive solution that resolves chronic plumbing problems and provides decades of reliable service without the need for frequent repairs. If your Boulder property is dealing with ongoing leaks, poor water quality, or low pressure caused by aging pipes, contact DNI Heating and Air to schedule an evaluation and discuss a full re-piping plan.
