The issues that bring most homeowners to our door — and the ones we fix every week.
01
Discolored water from the tap
Rusty or brown water often means the old pipes are corroding inside.
02
Frequent pinhole leaks
Small leaks popping up in different spots usually mean the pipes are failing.
03
Low water pressure
Years of mineral buildup inside old pipes can choke off flow throughout the home.
04
Outdated galvanized or polybutylene pipes
Older pipe materials are prone to corrosion and unexpected failures.
05
Banging noises in the walls
Loose or aging pipes can knock against framing when water moves through them.
06
Visible corrosion on exposed pipes
Green or white buildup on fittings is an early sign pipes are wearing out.
Frequently asked questions.
Straight answers to what homeowners ask us most. Still unsure? Call — we’re happy to talk it through.
Signs include frequent leaks, low pressure, rust-colored water, climbing water bills, visible corrosion, and recurring clogs. Schedule an assessment.
Most projects require permits from the City of Allentown Bureau of Building Standards & Safety. Our team handles applications and inspections.
Municipal water minerals cause scale buildup in older steel and iron pipes. We recommend PEX or copper and provide advice to protect your system.
Most projects are completed within 2 to 5 days depending on the size and complexity of the home.
We use modern methods to minimize disruption and carefully repair any areas that need to be accessed.
Yes. All repiping work is performed by licensed and insured technicians led by master plumber Dan Dunn with more than 25 years of experience with residential plumbing systems.
If the problems are concentrated in one area of the home, a partial repipe of that section can be cost-effective. If deterioration is widespread or the pipe material has reached the end of its lifespan throughout the system, a full repipe is the more reliable solution.
In most cases yes. Water is shut off during working hours but restored each evening. If the work is particularly extensive or if the home has a single bathroom, we discuss the schedule in advance so you can plan for the temporary inconvenience.
In some cases pipes can be rerouted through walls or above ceilings to avoid cutting into a finished basement floor. The approach depends on the layout of your plumbing system, and we plan the least invasive route before starting any work.
Yes. If rust-colored water is caused by corroding supply pipes, repiping eliminates the source of the contamination. If the discoloration comes from the water heater tank or the main supply, additional steps may be needed alongside the repiping.
Yes. Old pipes that have narrowed from corrosion or scale buildup restrict water flow and reduce pressure at every fixture. Replacing those pipes with properly sized new material restores full pressure throughout the home.
Yes. We always provide a detailed written estimate before any repiping work begins that covers the scope, materials, and timeline. There are no hidden charges, and we review the estimate with you so you understand exactly what is included.
Not necessarily. Low pressure in a single area can often be caused by a clogged aerator, a partially closed valve, or a damaged section of pipe that only needs to be repaired. We assess the system to determine whether the problem is localized or widespread before recommending a course of action.
Yes. We serve homeowners throughout Eastern Pennsylvania including Allentown, Lansdale, Quakertown, Doylestown, Warrington, and many other communities across Bucks, Montgomery, and Lehigh counties.
Coverage depends on the cause and your specific policy. Sudden damage from a burst pipe may be covered, while gradual deterioration is typically considered a maintenance issue and may not be. We can provide documentation of what we found to support a claim if applicable.
Yes. Replacing supply piping throughout a home requires a permit in most municipalities, and the work must be inspected before walls are closed. We pull the required permits and coordinate inspections as part of our standard repiping service.
A repipe does require water to be shut off during working hours on the days the team is on-site. Water is typically restored each evening so the household can function overnight. We work efficiently to keep the disruption as brief as possible.
Copper is more rigid and has a longer track record, and some homeowners prefer it for its durability and resale perception. PEX is more flexible, easier to route through finished spaces, and less susceptible to freezing. We discuss the pros and cons of each based on your specific home.
Signs that pipes may need replacement include rusty or discolored water from the taps, frequent pinhole leaks appearing in different locations, noticeable drop in water pressure throughout the home, and visible corrosion on exposed pipe sections.
We plan entry and access points carefully, using existing openings where possible and making targeted cuts where they are least visible. We document each opening location so patching can be done efficiently after the plumbing work is complete.
Hard water deposits scale inside pipe walls, which gradually narrows the interior diameter and restricts flow. Over many years, significant mineral buildup can reduce pressure noticeably and cause fittings and valves to fail prematurely.
A whole-home repipe typically takes two to four days depending on the size of the home, the accessibility of the existing pipes, and the material being installed. We give you a clear schedule before work begins so you can plan accordingly.
Copper piping can last 50 or more years in the right conditions. PEX has a rated lifespan of 25 or more years and is less susceptible to corrosion than metal pipe. The actual lifespan depends on water chemistry, installation quality, and maintenance.
Galvanized steel pipe is not immediately dangerous, but it corrodes from the inside and can reduce water flow, discolor the water, and increase the risk of pinhole leaks over time. Many homeowners choose to repipe when galvanized pipe begins to show these signs.
Pinhole leaks in copper pipe are caused by pitting corrosion, which can be triggered by aggressive water chemistry, high chlorine levels, electrical grounding issues, or sediment in the water supply. Homes with repeated pinhole leaks in the same section may need that section or the whole system replaced.
The old pipe material is removed and disposed of as part of the repiping project. If there is lead pipe in the home, we follow the appropriate handling procedures for safe removal.
PEX is a flexible cross-linked polyethylene tubing that is resistant to corrosion, scale, and freezing, and it can be run in long continuous lengths that reduce the number of fittings needed. It is one of the most widely used materials for residential repiping today.
Repiping is the process of replacing some or all of a home's water supply pipes with new material. It is typically needed when pipes are old and corroding, when there are repeated leaks, or when water quality or pressure has declined significantly.
Supply pipes carry pressurized water to your fixtures and appliances. Drain pipes carry wastewater away from the home by gravity. Repiping usually refers to replacing supply pipes, though drain lines can also be replaced if they are blocked, cracked, or deteriorated.
We repipe with PEX, copper, or CPVC depending on the application, budget, and local code requirements. PEX is flexible, resistant to freezing, and faster to install. Copper has a long track record and is highly durable. We recommend the best option for each home.
Older homes in the Lehigh Valley and surrounding area often have galvanized steel, lead, or original copper supply pipes. Galvanized steel rusts from the inside out and narrows over time. Lead pipe is a health concern. Both are commonly replaced when a home is repiped.
Check for any visible drips at connection points over the first few days and monitor your water bill to confirm usage is back to normal. We pressure test the system after installation, but a few days of personal monitoring helps catch any issues early.
We plan every repipe carefully to minimize damage to your home, pull all required permits, and back our work with a labor warranty. Our team has the experience and equipment to handle both partial repairs and full whole-home repiping efficiently and professionally.
New piping with proper insulation actually helps maintain hot water temperature better than old, corroded pipes because there is less heat loss through the pipe walls. You may notice improved hot water performance after repiping.
Yes. Replacing supply pipes typically requires accessing the lines through walls, ceilings, or floors. We plan the work to minimize the number and size of openings, and we explain what will need to be patched or repaired after the plumbing is complete.
