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 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 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
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 We’re also equipped to replace outdated pipes to protect your property from significant damage.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
For residential or commercial basements that experience frequent flooding, a sump pump can help divert the water away from your property. Even minor flooding can lead to significant damage to your basement and the foundation of your home or business. A Delaware plumber can expertly install and provide ongoing maintenance for your sump pump to keep your basement dry and protected.
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
Experiencing irregular water pressure in your property? Problems like clogs, faulty valves, leaks, limescale buildup, or pipe corrosion can be the culprits. An Oliver plumber in Delaware can inspect your plumbing system and resolve the issue, helping to avoid any major plumbing damage.
Water Treatment Systems
Unfortunately, there could be dangerous contaminants hidden in your tap water, such as aluminum, ammonia, arsenic, lead, mercury, and more. We recommend installing a water treatment system that filters your water, making it safe to drink. Our experts can help you choose the right system.
Peace Of Mind Membership Maintenance Plan
Regular maintenance is vital for keeping your Delaware residential or commercial plumbing system in good working order. Our Peace of Mind Membership maintenance plan ensures that your pipes and fixtures remain efficient and free-flowing. This plan not only helps your faucets and water heater last longer but can also reduce your water bill if leaks are addressed. Additionally, you’ll benefit from a 10% discount on any plumbing services you may need.
