"Super Service Today didn’t respond in a timely manner, over-quoted us by a thousand dollars, mis-diagnosed our problem in a way that could have proven catastrophic (if we hadn’t gotten a second opinion), and then tried to withhold the return of our deposit to try to get us to sign an “agreement” that we wouldn’t post a bad review. The order of events: 1. Response in a timely manner: Our toilet and two sinks overflowed, with water cascading down from that bathroom to the basement below. We went with Super Service Today because they were the first phone call to an emergency plumber to get through, and had reasonably good reviews online. The overflow stopped on its own, and the company said it wasn’t that much of an emergency, so they’d stop by between 8 and 10 the next morning. At 10am, I called them, as no one had shown up. They apologized and said someone would definitely be there by noon. At noon, I called them again, and told them we were going with another plumbing company. They said they’d sub-contract someone else, in order to keep control of the situation. The company they sent found the blockage, snaked the pipe, and hit a blockage in the sewer leading to the street; they couldn’t investigate further, because they were only sub-contracted. 2. Over-quote and mis-diagnosis: Super Service Today sent one of their plumbers to take a video of the sewer line. This person hit the same blockage and diagnosed the problem as tree roots, then laid out escalating packages to fix it. The lowest level (and what this plumber recommended wholeheartedly) was hydro-jet, a high-powered water burst that can clear tree roots; this was quoted at $1600. The next level was replacement of that segment ($5000 or so) or replacement of the whole sewer ($25000 or so). He said the problem as urgent, and urged us to pick the jet. I hesitantly agreed and paid the deposit. Later that day, I got uncertain and curious and looked up what other companies charged for hydro-jet, and found it was between $300 and $500. At this point, we cancelled our hydro-jet service with Super Service Today and searched for another company. The company we chose took a new video of the line and showed us the truth: there was a mis-join in the line, rather than tree roots, so the two segments were partially offset from each other. They told us that if we’d chosen the (overpriced) hydro-jet, we’d have likely created an enormous sinkhole and done catastrophic damage to our sewer system. We went with them for the repair of that sewer segment, which went smoothly. 3. Withholding our deposit and the agreement: We wanted to conclude business with Super Service Today and get our deposit back. Super Service Today sent us a legal document to sign in order to get our deposit; it stated that we would be prohibited from posting a negative review. I consulted a lawyer friend who confirmed that we needed no “agreement” to get our deposit back, and that this was fraudulent. They tried to force the issue one more time and only relented when we said we’d submitted a challenge claim to our credit card company for the charge. Then, they were very apologetic on the phone as they returned our deposit, as well as an extra $100 refund for our trouble."

We offer turnkey solutions for both residential and commercial customers — no job is too large or complex for our expert team.

"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

Water heater services FAQs

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.

It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.
