Harris Plumbing, Heating, Air & Electrical provides residential plumbing services throughout New Castle and Kent Counties. From everyday repairs to equipment installation and ongoing maintenance, our plumbers help keep water moving safely and reliably through your home.

We serve homes across Wilmington, Newark, Bear, Middletown, Smyrna, Dover, and surrounding Northern Delaware communities. Our team works with older plumbing systems, newer construction, private wells, finished basements, and homes where several generations of piping and equipment have been installed over time.

Complete Plumbing Services for Northern Delaware Homes

A plumbing system includes more than visible fixtures. Supply piping, valves, water-heating equipment, pressure controls, pumps, and underground lines all need to work together.

Our plumbing services cover the repair, installation, replacement, and maintenance of the systems that deliver and control water throughout the home. We begin by identifying what is affected and whether the problem is isolated or connected to a larger plumbing condition.

Plumbing Repair

Plumbing problems are not always limited to the fixture where the symptoms appear. Water beneath a sink, near a utility area, or across a finished ceiling may originate from a failed pipe, valve, connection, or nearby equipment.

Our plumbing repair work includes:

  • Leaking and damaged piping

  • Failed valves and supply connections

  • Low or inconsistent water pressure

  • Fixture and appliance connection problems

  • Frozen or deteriorated pipes

  • Plumbing equipment leaks

  • Sudden interruptions to water service

We inspect the affected area and surrounding plumbing before recommending work. That helps us repair the source of the failure rather than only addressing the visible water.

Plumbing Installation

Plumbing installation may be needed during a renovation, equipment replacement, fixture upgrade, or larger change to the home.

We plan new plumbing around the condition of the existing system, available space, water pressure, household demand, and access for future service. This may include new supply piping, shutoff valves, equipment connections, or changes needed to support a remodeled space.

Before work begins, we explain how the installation connects to the rest of the plumbing system and whether any aging or incompatible components should be addressed at the same time.

Plumbing Maintenance

Regular plumbing maintenance can help identify developing leaks, corrosion, pressure concerns, and equipment wear before they result in a larger failure.

The service should reflect the home rather than follow one generic checklist. An older property may need closer attention to exposed piping and valves, while a private-well home may depend more heavily on pump controls and pressure equipment.

Maintenance can include inspection of accessible pipes, shutoffs, equipment connections, water pressure, pumps, and water-heating components. We focus on the areas most likely to affect reliability or cause water damage.

Plumbing Services for Specific Household Needs

Some plumbing problems require a more specialized service. We route homeowners to the right team based on the equipment or system involved.

  • Urgent plumbing failures: Request 24-hour emergency plumbing service for burst pipes, active flooding, overflowing fixtures, sudden water loss, and other problems that cannot safely wait.

  • Hot-water problems: Our water heater services cover repair, replacement, installation, and maintenance for tank and tankless systems.

  • Basement water protection: Schedule sump pump service for failed pumps, backup systems, discharge problems, or new installations.

  • Hidden plumbing leaks: Our leak detection services help locate concealed pipe failures, underground leaks, and slab leaks before repairs begin.

  • Private water systems: Request well pump service for low pressure, short cycling, complete water loss, or failing pump and pressure equipment.

Plumbing for New Castle and Kent County Homes

Northern Delaware includes dense older neighborhoods, expanding suburban communities, and rural properties with very different plumbing systems.

Homes around Wilmington, Newark, and New Castle may have older valves, aging supply lines, and plumbing concealed behind finished basements or previous renovations. Properties near Middletown, Smyrna, and Dover may have larger households, multiple bathrooms, and greater demand on water-heating and pressure systems.

Some homes also rely on private wells or sump systems that become especially important during heavy rainfall and seasonal groundwater changes. We account for those local conditions before recommending plumbing repair, installation, or maintenance.

Our Plumbing Service Process

We begin by reviewing the problem, the affected fixtures or equipment, and any recent changes in water pressure, usage, or performance.

Our plumber then inspects the relevant parts of the system, identifies the source of the issue, and explains the available options. Once the work is approved, we complete the repair or installation and test the affected plumbing before leaving.

For planned projects, we also review access, capacity, utility requirements, and any supporting work needed for a dependable installation.

Had Harris out to do an assessment on my heater and the technician Chris found a dangerous situation with my heater exchanger that could have slowly put carbon monoxide into my house. I’m grateful that Lee was able to come to the house right away and provide me selections and options. I was able to get a new HVAC system the next day and my family can safely sleep in our home. Everyone from Mathew and Chris M to Lee and the install guys, Louis, Mike and Jhar were amazing and genuinely great people I would have in my home any time.

I was quite satisfied with meeting with Josh, yesterday. While I didn't care for the price, I had to expect things would be that high of a cost. Still, Josh's professional conduct while he was inspecting my tank made it that much easier to say, "yes," and go ahead with the installation request. I am not concerned, at this point, about the job itself. The heater installation, earlier this year was very nicely done and the unit is working great.

The technician first of all was polite, he put his booties on. And I appreciate that because I have hardwood floors original. The technician looked at the situation was able to fix the issue and showed me what can be another possible problem if not addressed.

Requested same day service in the AM and Scott was at the house by 3:00. He was very knowledgeable and professional, making sure that he understood what I wanted regarding the outdoor outlet and the line to it. He worked quickly and left the patio cleaner than when he arrived. I would highly recommend Harris for electrical work.
