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
Toilets may not have many components, but they can still face a variety of problems that need expert attention. Issues like clogs, leaks, constantly running water, and unusual sounds are common. While normal use causes parts to wear out, overusing certain cleaning products can accelerate deterioration and lead to more frequent repairs.
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
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
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 We’re also equipped to replace outdated pipes to protect your property from significant damage.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
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 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 Delaware property to assess and restore your sewer lines to working order.
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
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.
