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
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
As a homeowner or business owner, you rely on a properly functioning water heater. From a lack of hot water to leaks or unusual odors, water heaters can face various issues. Oliver’s skilled plumbers are ready to install, repair, or replace your water heater at an affordable price, ensuring consistent hot water for your entire 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
Drains are designed so that water and waste can flow quickly to and from your property. When they're clogged and don't flow freely, a variety of issues can develop. If you have a problem with your sink or sewer pipe, an Oliver plumber can diagnose and take care of it quickly so that your drains work correctly again.
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 are not common, but they can happen, especially if your pipes have been in place for many years. Extreme cold, fluctuating temperatures, and neglecting minor issues can lead to major problems that need professional repair. If needed, we can replace your aging pipes to help prevent serious 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 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 Wilmington 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
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 experiencing low or high water pressure in your home or business? A number of issues can cause this problem, such as clogs, faulty valves, leaks, limescale deposits, and pipe corrosion. An Oliver plumber in Wilmington can inspect your pipes and take care of whatever is causing your low or high water pressure to avoid major 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
To ensure your Wilmington residential or commercial plumbing stays in excellent condition, regular maintenance is crucial. Our Peace of Mind Membership maintenance plan provides thorough care for your pipes and fixtures, improving their performance and longevity. This plan can also help reduce your water bill by addressing leaks and includes a 10% discount on any plumbing services needed.
