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
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
Regular maintenance is the key to making your boiler last for its intended life span or longer. Leaks, overheating, and strange noises can occur over time. However, regular maintenance can catch issues before they become expensive problems to fix. Oliver technicians can perform regular inspections and any necessary repairs that you need to keep your boiler running efficiently.
Drain Cleaning
Drains are meant to ensure the smooth flow of water and waste from your property, but clogs can disrupt this process and lead to various problems. If you’re experiencing issues with your sink or sewer pipe, an Oliver plumber can swiftly diagnose and resolve the problem, restoring proper function to your drains.
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
Pipe leaks and bursts aren't a regular occurrence, but they can occur when your pipes have been installed for several decades. Below freezing temperatures, temperature fluctuations, and ignoring minor damage can have disastrous consequences that require repairs by a plumber. If necessary, we can replace your old pipes to prevent significant 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
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 Delaware 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, 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
Keeping your Delaware residential or commercial plumbing in top shape requires regular maintenance. Our Peace of Mind Membership maintenance plan is designed to keep your pipes and fixtures flowing smoothly and efficiently. This plan helps extend the life of your faucets and water heater while potentially lowering your water bill if leaks are present. Along with routine inspections, you’ll also receive a 10% discount on any necessary plumbing services.
