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
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 We’re also equipped to replace outdated pipes to protect your property from significant damage.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 Middletown 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 Middletown 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
Low or high water pressure in your home or business can result from several issues, such as clogs, damaged valves, leaks, limescale deposits, or corroded pipes. An Oliver plumber in Middletown can examine your plumbing and fix the problem to prevent further damage and maintain optimal water pressure.
Water Treatment Systems
Hidden contaminants like aluminum, ammonia, arsenic, lead, and mercury might be present in your tap water. To ensure it's safe for drinking, consider installing a water treatment system designed to filter out these pollutants. Our experts can help you find the ideal system for your water purification needs.
Peace Of Mind Membership Maintenance Plan
When it comes to making sure that your Middletown 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.
