Learn more about the specialized plumbing services we offer today.
Leaky Faucets
The steady drip of a leaky faucet isn’t just irritating, but it also leads to significant water waste. A faucet that drips once per second can waste up to 58 gallons of water in a week and as much as 3,000 gallons over the course of a year. Let Oliver send a plumber to fix or replace your faucet, helping you save both water and money.
Toilet Repair & Replacement
Although toilets don't have many parts, they can develop several problems that require professional repairs. Some of these include clogs, leaks, water that continuously runs, and strange noises. While toilet parts can deteriorate with normal wear and tear, using certain cleaning products too often could cause issues.
Water Heaters
Whether you own a home or a business, having a functioning water heater is essential. Water heaters can sometimes stop producing hot water, while other times, they may develop leaks or emit strange odors. An Oliver plumber can efficiently install, repair, or replace your water heater, ensuring reliable hot water throughout your property.
Boiler Service
Regular maintenance is essential for extending your boiler's life span and preventing costly issues. Over time, problems like leaks, overheating, and unusual noises can arise, but routine upkeep helps catch these issues early. Oliver’s technicians are equipped to provide thorough inspections and any needed repairs, ensuring your boiler operates efficiently for years to come.
Drain Cleaning
Drains are meant to ensure the smooth flow of water and waste from your property, but clogs can disrupt this process and lead to various problems. If you’re experiencing issues with your sink or sewer pipe, an Oliver plumber can swiftly diagnose and resolve the problem, restoring proper function to your drains.
Garbage Disposal
A basic reset might solve minor issues with your garbage disposal, but more serious problems usually require a professional plumber's intervention. We offer expert repair services for garbage disposals and can also recommend and install the perfect model for your sink if you're considering an upgrade or replacement.
Old Pipes
Pipe leaks and bursts aren't a regular occurrence, but they can occur when your pipes have been installed for several decades. Below freezing temperatures, temperature fluctuations, and ignoring minor damage can have disastrous consequences that require repairs by a plumber. If necessary, we can replace your old pipes to prevent significant damage to your property.
Sink Repair & Replacement
Whether you’re washing your hands or cleaning dishes, sinks are essential to your daily routine. Diagnosing sink problems can be tricky, but they usually involve either the faucets or the pipes. No matter what’s wrong with your sink, an Oliver plumber can address the issue and get everything back to normal.
Sump Pumps
If your basement, whether residential or commercial, floods often, installing a sump pump can effectively redirect water away from your property. Small amounts of flooding can still cause serious damage to your basement and foundation. A Wilmington plumber can handle the installation and routine maintenance of your sump pump, ensuring your basement stays 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
Sewer line problems can be very messy and smelly. If you notice flooding around your sewer lines, slowly draining bathtubs and sinks, or sewage backing up into your bathtub or toilet, you might need sewer pipe repairs. Oliver can send a plumber to your Wilmington property to assess and restore your sewer lines to working order.
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 Wilmington can thoroughly inspect your pipes and address the underlying problem to prevent significant plumbing damage.
Water Treatment Systems
Unfortunately, your tap water may contain harmful contaminants like aluminum, ammonia, arsenic, lead, mercury, and others. To ensure your water is safe to drink, we suggest installing a water treatment system that effectively filters out these impurities. Our experts are here to help you select the best system for your needs.
Peace Of Mind Membership Maintenance Plan
For reliable maintenance of your Wilmington 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.
