Our Ontario Plumbing Services

Sewer and Drain Line Repair and Replacement, Ontario, CA

For those in Ontario with older homes, if your drains are noticeably slow, backing up, or emanating bad odors, you may be in need of drain or sewer line repair or replacement. To determine the extent of the problem, give us a call and we’ll investigate. Many times it just requires a minor fix, but sometimes it’s not so easy. For those that can get by with a pipe repair, we offer trenchless pipe relining, also known as trenchless pipe rehabilitation. With this method of underground pipe repair, we dig one hole near the property and shoot in new pipe to fit the inner diameter of the old pipe. For those that require full or partial pipe replacement, there’s trenchless pipe bursting. In this method, we pull new pipe through the existing, which smashes the old pipe and leaves just the new pipe in it place. Both methods are highly effective and cost efficient, and we back all new pipe installations with a 20-year warranty. Call now for a free estimate.

Slab Leak Detection & Water Line Repair, Ontario, CA

Water line breaks can occur nearly anywhere: above ceilings, behind walls, in the yard, and under your foundation. When a pipe breaks behind the wall or ceiling, the location of the break is fairly obvious because of the ever-increasing wet spot forming; however, when the leak occurs under concrete or asphalt, the only sign of a leak is an abnormally high water bill. To locate hidden leaks, we use electronic slab leak detection equipment. By figuring out the exact location of the leak, we’re able to help you determine the best way to stop the leak and restore your water line. Options include replacing the pipe or closing off the pipe and rerouting it. For clients with expensive hardscaping or flooring, rerouting is often the preferred way to go. Call today to schedule our slab leak detection services at your Ontario home or business.

Drain Cleaning/Snaking and Hydro Jetting for Clogged, Smelly and
Slow Drains in Ontario, CA

At Steve’s Five Star Service, we provide affordable and effective drain cleaning services in Ontario. Our drain cleaning service is usually recommended when there are bad odors coming from drains, slow drains, and/or drain backups. It can be done on an as-needed basis or as part of your regularly scheduled plumbing maintenance as a preventative measure. We offer four different levels of drain cleaning to handle varying degrees of drain clogs. Snaking typically removes obstructions, such as paper towels and flushable wipes. Hydro jetting not only removes obstructions, but also thoroughly cleans the insides of your drains. If needed, we can use a sewer camera to determine if the pipe is clear or if any other problems need to be addressed. Finally, we can provide chemical treatments for Ontario properties that need to remove fat, grease, soap deposits, and more from their drains. For tree root intrusions, we typically use hydro jetting, but can also apply RootX, which can prevent future root intrusions. Call today to learn more.

Sewer Inspection, Repair, and Replacement, Ontario, CA

For clogged, aging, or cracked/broken drains and sewer lines, call Steve’s Five Star Service. We provide sewer line camera inspections that let us determine exactly what the issue is. Sewer line pipe repairs can be completed by excavating the site, or using trenchless rehabilitation (pipe relining) or bursting (pipe replacement). Most of our Ontario clients are surprised to learn that not only is trenchless pipe repair less invasive, but it’s also less expensive than traditional pipe replacement methods. Moreover, our new sewer lines are backed by a 20-year warranty.

Trenchless Pipe Relining & Bursting, Ontario, CA
(Drain Repair/Rehabilitation & Replacement)

With our trenchless pipe relining/bursting services, it is possible to repair or replace your drains and sewer lines with minimal damage to your property. With trenchless pipe bursting, we dig two relatively small holes and burst the old pipe by inserting new replacement piping. With trenchless pipe relining, we are able to rehabilitate the old pipe by shooting a whole new pipe into it. This new pipe lines the inner diameter of the pipe, and essentially gives it a whole new life. At Steve’s Five Star Service, we excel at trenchless drain/sewer line repair and replacement and offer this service to customers throughout Ontario. Call today to learn more.

Repiping, Ontario, CA: All Copper Repipe & Hybrid Repipe Systems (PEX & Copper)

Steve’s Five Star Service offers Ontario the best value in repiping. We can repair all or a portion of a home or business’s water lines using all-copper piping or a hybrid system consisting of both copper and PEX. PEX or cross-linked polyethylene is a flexible, plastic-type materials. In general, PEX is less expensive than copper, easier to install, and corrosion resistant. However, because it was developed within the last 30 years, it hasn’t been proven to offer the same longevity as copper. Yet, of the two options, our hybrid systems continue to be popular because they essentially offer all of the advantages of PEX and copper without any of their disadvantages. Call today for an on-site consultation. All new pipe systems are done to code and backed by a 20-year warranty.

This means guiding you through insurance paperwork and giving you contractor recommendations for any water cleaning, remediation, and restoration work you need done.

Salt-Free Water Conditioners/Softeners, Ontario, CA -- nuvoH2O Factory Authorized Dealer

If you suspect that you have hard water, consider calling the local water department and ask for a report or call us and we’ll conduct a water hardness test. Hard water can produce a number of undesirable effects, including reducing the efficiency of tankless water heaters; leaving spots on your dishes; making it hard to thoroughly wash away soap from your laundry, hands, and hair; and producing scale build up in your pipes. Your water’s level of hardness will determine what recommendations we make. For some of our clients in Ontario, we may suggest increasing the frequency of their plumbing maintenance schedule. In other cases, where the water is very hard, we may recommend a water softener. We are a factory authorized dealer for nuvoH2O, one of the leading brands of salt-free water conditioners/softeners currently available. Unlike salt-based conditioners, which are now outlawed or severely restricted in many cities across the Inland Empire, nuvoH2O’s systems can be installed in both homes and businesses across Ontario. nuvoH2O is not only effective at removing minerals from the water that can cause scale build up, but also significantly less than the salt-based systems offered by Culligan and Rayne. Call today for a free estimate.
