Ennis Plumbing is open for your needs during the current health crisis.We wear masks and practice social distancing. ***Super Service Award Winner 2014-2020***Have a current masters and contracting license, also insured. Never a trip charge. Always available-nights and weekends. I will always give a honest and up front answer. Ennis Plumbing LLC is also a member of the BBB with A+ rating and is a accredited business

"On a Monday morning, we woke up to a flooded basement bathroom floor. We called a few highly recommended Angie's List contractors, and James and his son were able to squeeze us in on Tuesday morning between appointments. They called 30 minutes before they arrived to inform us they were on their way. Once they arrived, they worked diligently to identify where the leak originated. They carefully removed only one tile from our basement bathroom shower to repair a cracked pipe in the wall under our kitchen. Once repaired, it was determined there were two more cracked pipes in the wall. They spent the better part of an hour identifying the leaks and where in the wall the cracked pipes were located. Again, they carefully cut discreet holes in the wall to repair the pipes. They recommend we have our pipes snaked to clear out any blockage and referred us to gentleman that was able to come the same afternoon. The snake he brought was 25 feet, and we were now experiencing some slight leakage under the kitchen sink. James texted us that evening to see how it went. We told him, and he said he would stop by in the morning to check everything again. After several tests of the dishwasher, full sinks, etc., it was fixed. Whatever was caught in the pipe was gone. We decided to have our main line scoped just to be safe. James said we didn't need to and recommend we cancel our appointment, but referred us to a reputable company anyway. The scope was clear, but the gentleman recommended we have our clean out replaced. My husband decided to replace the cap instead and texted James to discuss his plan to do so. James and my husband have been texting for the past few days to ensure all is well with the pipes and the cap. James and his son are incredibly thorough and follow up on their work. I would highly recommend them to anyone looking to have pipe/plumbing repairs. Thanks!"

Additional Guarantees- We Value Your Safety- No Blame Game-We Value Your Time-Apples to Apples -Workmanship

"DO NOT USE THIS COMPANY. Please look at the YELP or BBB complaints, they are much more akin to what I experienced. They are certainly manipulating the Google reviews. I hired Lion to do a simple cleaning/certifying of our HVAC units as part of a sale. I was initially quoted $119, and I verified no less than 3 times with the customer service rep that the price would include cleaning and testing. When our tech showed up, he said we were misquoted and the charge for cleaning and testing would be about $450, as it was part of their "maintenance" package. They very reluctantly cut us a "deal" for just over $300. Not only was zero cleaning done, the tech did not perform a single action that could be classified as "maintenance." What we got was a diagnostic and estimate for repairs and replacement. I called to complain twice before someone finally got back to me. I was told that the tech didn't perform the cleaning because it may have damaged the unit, which was clearly a lie because the tech never told me that and actually gave me a quote to perform the AC coil cleaning, $470 (what a deal!). The rep then told me that a simple cleaning was done, but not the deep clean that I was expecting. I asked that my invoice be revised to reflect that, but was quickly blocked. Yes, they actually blocked my number after repeatedly misrepresenting both the price and work. I was shocked. I filed a complaint with the BBB, of which I discovered there are many. Hopefully they do the right thing and just give me a refund, but I won't hold my breath. Again, they are clearly manipulating their reviews on Google. Customers do your research!"

Screaming profanities in my home, never working, my husband ended up asking Shawn to leave. One of Bathrooms needed to be redone, because Shawn did all the work incorrectly.

Gas Leak Repair questions, answered by experts

The cost of repairing a gas leak depends on the type of leak, its severity, and how difficult it is for the repair technician to reach it. Some of the most common gas line repair costs, on average, include:

  • Cap a gas line: $75–$150

  • Gas system inspection: $150

  • Pressure test: $75–$500

  • Damaged or corroded pipe: $6–$7 per linear foot

  • Repair gas leak: $120–$5,000

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.

Yes. There are a variety of standard pipe sizes used in plumbing. The main supply line connecting your home to the street is either 3/4 or 1 inch in diameter. Supply lines are 3/4 inch in diameter. Individual components are 1/2 inch in diameter. Meanwhile, your main drainpipe is often 4 inches wide. Most shower and bathtub drains are 2 inches in diameter, most toilet drains are 3 inches in diameter, and most sink drainpipes are 1 1/4 or 1 ½ inches in diameter.

Yes, most states require a plumber to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. Check our state licensing tool to review the local plumber guidelines.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification, which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

Before you hire a natural gas plumber, it’s a good idea to get quotes from multiple pros to find the best value. When speaking with prospective plumbers, ask them if they’re licensed to work with gas lines, what precautions they take to ensure safety during the project, and how to handle an emergency if there’s a leak after the job. You may also want to know about warranties or guarantees, additional costs, how to prep your home, and if you’ll need to relight your pilot lights.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
