Leaky Faucets
A leaky faucet's constant drip is more than just a nuisance, it’s a major source of wasted water. With a single drip every second, you could be losing up to 58 gallons of water each week and 3,000 gallons annually. Call Oliver to have a plumber repair or replace the faucet, saving you money on your water bill over time.
Toilet Repair & Replacement
While toilets are relatively simple in design, they can still experience a range of issues that call for professional repairs. Common problems include clogs, leaks, continuous running water, and odd noises. Although wear and tear is expected over time, frequent use of harsh cleaning products can also contribute to these issues.
Water Heaters
Whether you're a homeowner or business owner, it's hard to live without a properly working water heater. Sometimes, water heaters don't produce hot water, but other times, they have leaks or strange odors. A plumber from Oliver can affordably install, repair, or replace your water heater so that you have hot water across your property.
Boiler Service
To ensure your boiler lasts as long as possible, routine maintenance is crucial. Over time, issues like leaks, overheating, or strange noises can develop, but regular checkups help address these before they turn into costly repairs. Oliver’s expert technicians can perform inspections and handle any repairs to keep your boiler running smoothly and efficiently.
Drain Cleaning
Designed for efficient water and waste flow, drains can encounter problems when they become clogged. Such issues can cause a range of complications. If your sink or sewer pipe is causing trouble, Oliver’s plumbers are ready to quickly identify and fix the issue, ensuring your drains are back to working properly.
Garbage Disposal
In some cases, a problem with your garbage disposal can be fixed with a simple reset, which is possible to do on your own. Other times, garbage disposal issues require the trained eye of a professional plumber. We offer specialty services that include repairing garbage disposals. For installations and replacements, we can recommend the ideal model for your sink.
Old Pipes
While pipe leaks and bursts aren't frequent, they can occur with older pipes that have been in use for decades. Cold weather, temperature changes, and ignoring minor damages can lead to severe issues that require a plumber’s expertise. We’re also equipped to replace outdated pipes to protect your property from significant damage.
Sink Repair & Replacement
Sinks play a crucial role in daily tasks, from handwashing to dishwashing. When issues arise, it can be challenging to identify the source of the problem. Typically, the issue involves the faucets or pipes. Regardless of the problem with your sink, Oliver’s plumbers are here to repair it and restore your sink to its normal function.
Sump Pumps
If you have a residential or commercial basement that floods regularly, you can redirect the accumulated water away from your property with a sump pump. Even a little flooding can cause costly damage in your basement and to the foundation of your home or business. A Delaware plumber can install and regularly maintain your sump pump to keep your basement dry.
Gas Lines
Plumbers are typically associated with water and sewer systems, but we also have the expertise to handle natural gas piping. The pipes for natural gas are similar to those used in water and sewer systems. We can professionally install your gas lines and expertly repair any leaks to ensure your system operates safely and efficiently.
Sewer Line Repair & Replacement
Problems with sewer lines can result in messy and odorous situations. Signs like flooding around sewer lines, sluggish drainage in sinks or bathtubs, or sewage backing up into your toilet or bathtub indicate that sewer pipe repairs might be needed. Oliver can dispatch a plumber to your Delaware property to inspect and restore your sewer lines to ensure they function correctly.
Tankless Water Heaters
Whether you're setting up a tankless water heater for the first time or need repairs or replacements for an existing unit, our skilled technicians are up to the task. We can handle repairs for nearly any make and model of tankless water heater. Our team uses only high-quality equipment to ensure that your system performs reliably for years to come.

Water Pressure Problems
Are you dealing with unusually low or high water pressure at your home or business? This issue can stem from various causes, including clogs, malfunctioning valves, leaks, limescale buildup, or pipe corrosion. An Oliver plumber in Delaware can thoroughly inspect your pipes and address the underlying problem to prevent significant plumbing damage.
Water Treatment Systems
Hidden contaminants like aluminum, ammonia, arsenic, lead, and mercury might be present in your tap water. To ensure it's safe for drinking, consider installing a water treatment system designed to filter out these pollutants. Our experts can help you find the ideal system for your water purification needs.
Peace Of Mind Membership Maintenance Plan
For reliable maintenance of your Delaware residential or commercial plumbing, regular upkeep is key. Our Peace of Mind Membership maintenance plan offers comprehensive support to keep your pipes and fixtures working efficiently. With this plan, you can extend the life of your faucets and water heater and potentially lower your water bill by fixing leaks. Plus, you’ll enjoy a 10% discount on all required plumbing services.
