When I saw water on the floor by the water heater, I immediately started a search for plumbers. Bruce called me within 5 minutes of my search and asked me to send pictures of the water heater so that he could get an idea of the problem. There was serious leaking and corrosion on the top and rusty seams on the sides. He spent around 30 minutes on the phone walking me thru the directions on how to shut everything down to avoid the danger of bursting or increased leakage. He came the next morning at the time scheduled and installed a new water heater, water and gas lines and water valve. I was extremely happy with the service, the response the professionalism, price and the attention to detail. When emergency issues like this occur, it helps when you have someone who you can trust to help you get thru it all and makes sure everything is ok, from the first call to the completion of the job, Bruce was great in all ways. I highly recommend him when you need quick, trustworthy and efficient service.

All In One Plumbing & Drains, Inc. removed and disposed of our old water heater at a $35 charge, they got the permit for us at a $50 charge plus the cost of the permit at City Hall, they picked up and transported the new water heater from Orchard Hardware, around 2 miles at a $35 charge and installed the water heater in around 4 1/2 hours and it passed inspection by the City the next day. Cesar and his apprentice were very courteous and friendly and did a good job and the only complaint I have about their service is the final price. The Thumbtack.com price they advertised online was $225 but the final price turned out to be $700, over 3 times what they advertised. I would have left off one more star in the rating but they are still cheaper than Sears and the other licensed contractors that quoted us prices on Thumbtack. A couple of the handymen on Thumbtack quoted less of a price but there's no guarantee with someone that's not a licensed and bonded contractor. I don't know what these quotes on Thumbtack are based on and I forgot to ask them about it but these people need to be more honest about their final estimates since $225 plus $120 plus the permit price of $47 doesn't equal $700 dollars.

I had a leak under my kitchen sink from a former plumber who installed the sink and couldn't get it to stop leaking... until I called Ocho plumbing it was fixed in ten minutes. I have also used their services to replace a water heater, and even remove an old broken washer and install a new one.

Isidrio is the BEST plumber (and tech) I've worked with. He was very professional, prompt, clean, and offered a very fair price. I've used him to install my water heater, fix a bathroom faucet leak, and he just remodeled by bathroom. It's hard to find people who are not just good at their job but who are also honest. I would recommend Isidrio for any job.

Rob and crew did an excellent job installing my new tankless water heater. He was very considerate, listened to my concerns, explained things to me, and did a great job with the installation at a fair price. He also offered a warranty on the installation. I ended up getting my own electrician to install the power for the unit, but before even coming out Rob also asked the needed questions and provided options for that. He even provided his estimate over thumbtack which few people were willing to do. If you're putting in tankless I would definitely recommend him.

Albert is awesome. He is a perfectionist with unmatched work ethic. He provides the best service, prices, and flexibility that I have EVER experienced with a plumber. His prices are very competitive and don’t be surprised if he comes over to quote and is ready to tackle the job right on the spot. Originally we just hired him to in stall a water heater but since he has installed 3 toilets, 1 tub, replaced all fixtures in showers and all valves. So it is no surprise that I would say yes I would hire Albert again and refer him to anyone that needs a plumber.

American Castles Mike To the RESCUE!!! The water heater at my rental property burst on a Friday afternoon causing some major damage to the house. The renters were furious because their items got damaged and the house wasn't inhabitable after that. On the inside, the bathroom wall and under stairway closet were all soaking wet and drywall/carpet/padding had to be removed immediately to prevent mole build up. On the garage side where the water heater located, the entire wall was destroyed. so I called my home insurance who provided me with their preferred plumber who quoted an additional $540 out of pocket on top of what the insurance was going to cover just so he can bring up the water heater installation to code! He told me that it will take him 1+ week to order the water heater (duh...get one from Home Depot take only 1hr...which is what Mike did) and that he can install a temporary water heater and will charge $137/wk! He also referred me to a water damage restoration company which I was not too happy with either. Since it was an emergency and I went with that company. They came in and ripped out all the wet drywall without caring for any molding; especially for garage doors and closet doors! It seemed like what ever the water heater didn't damage, they did. They also broke my water heater intake shut off valve. damage the water heater over flow copper pipe. All I can say is I will not use them again! Back to the plumber, something was smelling fishy about his quote and so I called and questioned this plumber. His response was "Well, I will need to flush out the gas line and calibrate your water pressure...upgrade to the new California safety quote...put in earthquake straps...install new vent line since the new water heater nowaday don't use the old vent line!". I was not convinces so I started to Google for good local contractor and AMERICAN CASTLES (Mike Tay is the owner) came up from Thumtack along with few others from other websites. I contacted them and they came in and provided me quotes. Mike was the last one I contacted. He arrived within 30min. He checked out the damages and explained to me what needs to get done sequentially to get everything back in proper operation for my tenants. Mike is very knowledgeable and very patient in explaining things. I told him what the plumber had said, he laughed and told me the whole thing was a rip off and a scam! Another crock of bull**** and advised me against it. He told me to call my insurance company to inquire about using other plumber. Sure enough I was offered the "cash out" option which I didn't even know was available. I took that option and went with Mike for the repair. Mike knows how important it is for my tenants to get the hot water running again once the water damage restoration company completed the clean up/dry out the area (took 1 week). As soon as that company removed their equipment, Mike had his crew come in the next day (Saturday) to repair the garage dry wall and finished the installation of the new water heater and brought it up to code on safety on Sunday! He even added the water pan and installed drain pipe for me. I didn't even know such a thing exists (talk about quality...he treats it like repairing his own home!). The best part is his charge for the whole job including new water heater, earthquake straps, valve, drain pan, vent and new connection is far way less than what that plumber was going to charge me. I loved the fact he took the time to show me how things should be done up to code and what works for my situation instead of just giving a price and walking away. He did an awesome job! Unfortunately my landlord insurance's deductible was so high, I asked Mike to give me a quote for fixing the damage in the garage and inside the house. Mike's quote was very competitive and the best part is he is always willing to work with me knowing my situation (thx Mike). My bathroom paint is 16 years old so it was a challenge to match the paint for the new wall. After only quoting me for painting a small wall inside the bathroom, Mike decided on his own to paint the entire bathroom without charging for it. Now that what I call TAKING PRIDE IN YOUR WORK AND STICKING TO YOUR WORD!!! My summary is, Mike successfully completed the entire job and installation in four days. I would highly recommend Mike to anyone and will definitely be using and referring him to everyone I know.

My tankless hot water heater died and Midwest came out the same day I contacted them via Thumbtack July 3rd). Mike removed and replaced my old water heater on the same day and worked until midnight to complete the job. Awesome! Big thanks for getting my hot water up and running again, and this was all on Monday, July 3rd, when most places were closed due to the holiday.

I never write reviews but had to write one for Aux Rooter. My aunt's water heater has been broken for 5 days. After getting an overpriced estimate from Home Depot, I had to find another service. Someone that was honest, knowledgeable, and reasonable, but most importantly honest was key. I got 3 estimates (with Aux Rooter being the 3rd one) she decided to go with them and she is SO happy she did! My aunt who can barely speaks English RAVED about this service! So I knew I had to write a review. Will DEFINITELY recommend to others! Thank you Aux! 🤗

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

When is it time to replace a water heater?

Although regular water heater maintenance and water heater repair may extend the life of your hot water heater, it won’t last forever. Most water heaters have a life expectancy of about 10 years. Many water heaters need to be replaced when they’re 8-12 years old — that’s when they start to show signs of fatal wear, such as leaking around the base of the tank. A water heater should be replaced when it fails to sufficiently heat water for the home; if your heater is operating erratically, check first for a blown fuse or a tripped breaker to make sure an electrical issue isn’t causing the problem. Another time to replace a water heater is when you want to upgrade to either a larger model or a more energy-efficient one.

How long is a water heater supposed to last?

Your water heater is an essential part of your home, heating water for showers, dishwashing, laundry and more. On average, a traditional water heater will last 8-12 years. The general consensus is that it’s better to replace your water heater with a new one than to repair one that’s 10 years old or more. Older models are less energy-efficient and thus more costly to run than newer models with better technology. Here are some indicators of when it may be time to replace an old water heater instead of repairing it:

  • Leaks: If leaking is not caused by loose connections, the water may be seeping out through slight fractures in the metal of the tank that have formed over time.
  • Strange noises: Clanking, rumbling and other noises can mean that sediment has formed on the base of your tank, contributing to fissures leaks, and inefficiency.
  • Age: If it’s more than 10 years old, it’s probably time to replace.
  • Discolored or rusty water: Have a pro check it out; if the problem isn’t resolved by draining and cleaning, you’ll want to replace the heater.
  • Lack of hot water: Inconsistent heating and hot water supply that runs out too quickly likely means it’s time for a new unit.

Who can fix a water heater?

When a water heater stops running effectively, it’s best to hire a water heater repair professional to troubleshoot the problem. Whether it’s a plumbing company that offers water heater repair services or a provider specializing in water heater repair and maintenance, most repair companies offer same-day service as well as weekend and after-hours emergency calls. Usually, water heater repair professionals are experts in both electric and gas systems, as well as tank and tankless heaters, and can repair any kind of unit.

Why is my hot water not working?

The most common complaint among homeowners is that their hot water isn’t working — and the water heater is generally the culprit. Typically, it isn’t making the water as hot as you’d like it to be. When the water isn’t hot enough — or isn’t hot at all — run through this troubleshooting checklist for basic water heater repair tasks:

  • Make sure the power is connected to the heater, then reset the thermostat.
  • If it’s a gas water heater, make sure the pilot light is lit.
  • Raise the temperature setting on the thermostat.

If these stops don’t lead to hot water, it’s time to either check the heating element in an electric water heater or the burner unit and gas control valve in a gas-powered heater. A water heater repair and maintenance company can handle these repair jobs. However, if your hot water heater is eight years or older, it may be time to replace the water heater instead of repairing it.

Why is the water in my house not getting hot?

If the water in your house is not getting hot, it may be time for water heater repair. Nationally, the average water heater repair cost ranges between $120 and $200, although prices can range up to $400, depending on the problem and materials. Competent homeowners may also be able to try DIY fixes, whether they have a traditional gas or electric water heater or a tankless gas or electric heater. Troubleshooting the different issues that can arise with each of the styles requires some knowledge of how they operate and what red flags to look out for. For a natural gas water heater, the first step is to check whether the pilot light has gone out. It’s important to follow the manufacturer’s directions if you want to relight it yourself. If you smell gas, stop everything and call your gas company — the smell could signal a dangerous gas leak. If your household’s water is not getting hot enough, you can try increasing the temperature on the water heater’s front dial above the standard setting of 120 degrees; for safety, always turn off electricity to the unit before adjusting temperatures. If you keep running out of hot water, your household may simply need a higher-capacity water heater, so consider upgrading. Quick professional fixes include replacing the thermostat or heating elements and cleaning and repairing the thermocouple.

Hire skilled professionals for absolutely everything.
