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
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
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
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
From washing your hands to washing the dishes, sinks are an important part of your everyday life. When problems develop, it can be hard to pinpoint the cause. However, the faucets and pipes are the two main components. No matter what problem you have with your sink, an Oliver plumber can repair it so that you can get back to normal use.
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 Delaware plumber can handle the installation and routine maintenance of your sump pump, ensuring your basement stays dry.
Gas Lines
While plumbers are commonly linked with water and sewer systems, we’re also skilled in installing and repairing natural gas piping systems. The pipes used for natural gas are quite similar to those for water and sewer lines. We ensure that your gas lines are installed correctly and address any gas leaks with precision.
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
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.

For reliable maintenance of your Delaware 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.
