Leaky Faucets
The constant drip of a leaky faucet is not only annoying to hear but also wastes water. If one of your faucets drips once every second, you could be wasting up to 58 gallons of water in just one week or up to 3,000 gallons in a year. Oliver can send a plumber to repair or replace your faucet, saving you money in the long run.
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'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
Sometimes, you can fix a garbage disposal issue with a simple reset, which is something you can do yourself. However, more complex problems often need a professional plumber’s expertise. We provide specialized services for repairing garbage disposals and can help you choose and install the best model for your sink if a replacement is needed.
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 We’re also equipped to replace outdated pipes to protect your property from significant damage.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
Sewer line issues can be both unpleasant and problematic, often leading to mess and odors. If you’re experiencing flooding near your sewer lines, slow drainage in your bathtubs or sinks, or sewage backups in your toilet or bathtub, sewer pipe repairs may be necessary. Oliver can send a plumber to your Delaware property to evaluate and repair your sewer lines, getting them back to proper working condition.
Tankless Water Heaters
Whether you're installing a tankless water heater for the first time or require repairs or replacements for an old one, our technicians are well-trained and experienced. We can fix nearly any brand and model of tankless water heater. Using only top-tier equipment, our expert plumbers ensure your system is built to last and deliver consistent performance.

Water Pressure Problems
If you're facing issues with low or high water pressure, it could be due to factors like clogs, faulty valves, leaks, limescale accumulation, or pipe corrosion. An Oliver plumber in Delaware can evaluate your plumbing system and resolve the problem to protect your property from potential plumbing damage.
Water Treatment Systems
Your tap water might be harboring dangerous contaminants, including aluminum, ammonia, arsenic, lead, and mercury. To protect your health, consider installing a water treatment system that purifies your water. Our professionals can assist you in choosing the most suitable system for clean, safe drinking water.
Peace Of Mind Membership Maintenance Plan
When it comes to making sure that your Delaware residential or commercial plumbing remains in proper working order, regular maintenance is essential. We offer a Peace of Mind Membership maintenance plan to ensure that your pipes and plumbing fixtures flow freely and efficiently. This plan can make your faucets and water heater last longer as well as reduce your water bill if you have leaks. In addition to regular inspections, the program includes a 10% discount on any needed plumbing service.
