Frequently Asked Questions
A standard toilet repair (like a fill valve or flapper replacement) typically ranges from $150 to $300. For a new installation, labor costs usually fall between $250 and $1500. This price assumes the floor flange and shut-off valve are in good condition; if the subfloor is rotted or the flange is broken, we provide an updated estimate for the structural work.
This is usually caused by a degraded flapper that no longer creates a watertight seal, or a fill valve that is set too high, allowing water to spill into the overflow tube. It’s a silent leak that can waste up to 200 gallons of water a day. Replacing these internal components is a fast, cost-effective way to stop the waste.
A puddle at the base almost always points to a failed wax ring seal. When the wax ring stops sealing the connection between the toilet and the sewer flange, water escapes every time you flush. This must be addressed immediately to prevent the wooden subfloor from rotting and causing the toilet to eventually collapse.
A rocking toilet is often caused by an uneven floor or a closet flange that sits too high. However, it can also mean the floor underneath has become soft due to a long-term leak. We level the unit and secure it with shims and new closet bolts to ensure it’s stable and the seal remains intact.
The porcelain itself can last 50 years, but the internal moving parts usually fail every 5 to 7 years. If your toilet is an older model (pre-1994), it likely uses 3.5 to 7 gallons per flush. Upgrading to a modern High-Efficiency Toilet (HET) that uses 1.28 gallons per flush can significantly lower your monthly water bill.
No. Porcelain cracks are structural failures and cannot be safely patched. Even a hairline crack can suddenly burst under pressure, leading to a catastrophic flood. If we identify a crack in the tank or the bowl, we recommend an immediate replacement of the entire unit.
This is often caused by low water levels in the tank, a clogged "jet" hole at the bottom of the bowl, or a partial blockage in the trap. Over time, calcium deposits can also clog the rim holes where water enters the bowl. We clear these passages and adjust the lift chain to ensure a full, powerful flush.
These models sit about 2 inches higher than standard toilets (approx. 17-19 inches). They are compliant with ADA standards and make sitting and standing much easier for people with knee or back issues. They have become the standard choice for most master bathroom upgrades in 2026.
If the valve is an old "multi-turn" style and feels stiff or shows white mineral crusting, yes. These valves often leak the moment you try to use them after years of sitting idle. We install modern quarter-turn ball valves that are much more reliable and easier to operate in an emergency.
Yes. A toilet that is overflowing or completely backed up is a major sanitary issue. We offer 24/7 emergency response to clear the blockage, inspect the line with a camera if necessary, and ensure your bathroom is safe and functional again.

Posted on Google Omied LeleTrustindex verifies that the original source of the review is Google. Pasha (technician) was very helpful. We had a clogged drain and were unable to clear it ourselves. He arrived and fixed the drain and was very clean and polite. Left everything as it was before he arrived. Highly recommend.Posted on Google Liang KatherineTrustindex verifies that the original source of the review is Google. Fantastic service! We really enjoyed working with United plumbingPosted on Google Natalia ShreveTrustindex verifies that the original source of the review is Google. Pasha was very professional he gave us a couple of options and finished the plumbing job very quicklyPosted on Google Just JaniceTrustindex verifies that the original source of the review is Google. As a busy homeowner I truly appreciate their ability to work around my schedule and needs. My garbage disposal recently died, and Neo was professional and offered my different options. He had the parts I needed and was able to complete the job quickly and cleanly.Posted on Google Chaozhong LianTrustindex verifies that the original source of the review is Google. I wholeheartedly recommend United HVAC, Plumbing & Electrical. I recently hired them to replace the original 1961 HVAC ductwork in my house, and they did a wonderful, extremely professional job. I am beyond satisfied with the results. You don't just have to take my word for it--I actually took pictures of their completed work, uploaded them to Google Gemini, and asked the AI to evaluate the installation. Even the AI praised their work, calling it a "top-tier, textbook installation"! (See the screenshots below). During the bidding process, I compared United with another company. United's quote was slightly higher, but choosing them was absolutely the best decision. Their program manager, Tim, was incredibly easy to work with. He quickly identified asbestos tape on my 1961 ducts and insisted we use a C-22 licensed abatement company to remove it safely and provide all the legal documentation for future reference. The other company offered a cheaper route by doing the removal themselves, but for something as dangerous as asbestos, doing it by the book is well worth the minor price difference. I also want to give a massive shoutout to Bair (Bayar) for his exceptional craftsmanship. He is easy-going, friendly, and really listened to all of my concerns. He provided great recommendations on how the new ductwork should be organized, and actually used a machine to fine-tune and balance the air pressure throughout the house. To top it all off, he even carefully reorganized the insulation in my attic after the work was done! It's this kind of attention to detail that makes them stand out. The pictures speak for themselves. If you want true professionals who care about safety, honesty, and quality craftsmanship, go with United HVAC.Posted on Google Chaozhong LianTrustindex verifies that the original source of the review is Google. I highly recommend United HVAC, Plumbing & Electrical! From start to finish, the entire process was incredibly smooth. They handled all the permits and inspections throughout the project, which gave us complete peace of mind. Every single technician we interacted with was friendly, approachable, and truly easy to work with. I specifically want to give a massive shoutout to Max (Aiusha) and Rinat for their wonderful work. Max is super professional and highly skilled. He installed my water heater and water softener with absolute "military precision." I'm the kind of guy who has a lot of weird, specific ideas about how pipes should be routed and extra gadgets I want installed to monitor the system, and Max handled all my requests with total ease. I am also super paranoid about plumbers plowing through studs or structural beams in my 1961 house, but Max was extremely careful and treated my home's structure with the utmost respect. Rinat is also a fantastic plumber. He installed a PRV, a Moen Flo auto-shutoff valve, an RO system, and even replaced some of the old sewage pipes in my house. He really listened to all of my requests and finished the job quickly and professionally. I highly recommend him! Because of their wonderful service, I’ve officially signed up for their company's membership. I am currently working with them to redo my HVAC ductwork, and I will definitely leave another review for that project once it's done. I'm sure they will do a wonderful job there, too!Posted on Google Ritesh BediaTrustindex verifies that the original source of the review is Google. Great service. Loved the professionalism and the way fixed my plumbing problem. I would call them again.Posted on Google Ginger PerngTrustindex verifies that the original source of the review is Google. We had to replace the wax ring on our toilet. Scheduling was easy; pricing was fair (much cheaper than the other quote we got!) Our technician, Melvin, was polite and expedient. This is our second time using United and highly recommend for gas and plumbing services.Posted on Google Joseph MartinTrustindex verifies that the original source of the review is Google. Melvin was great. Fast and efficient.
