Roto-Rooter is America's Largest Plumbing and Drain Cleanng Company. We offer 24 hour services with no overtime or after hour charges. We also offer convenient finance options

"BUYER BEWARE! Had a pipe leak within my wall. Caught it fairly early with minimum damage. The Roto Rooter rep Brian came out and inspected and said I needed water mitigation based off the moisture in my walls. When I say the leak wasn't that bad, it really wasn't! He stated that my insurance company would cover it all and that he deals with my particular company all the time and not to worry. I obviously was taken back by the cost of almost 4k! Fast forward, my insurance company are questioning duplicate charges and Roto-Rooter is saying I owe almost 3k or a lien will be placed on my property! This whole water mitigation is a scam and the salesman did not tell the truth. They should have picked up their fans a lot earlier than they did. I'm sure they were trying to milk all the money they could. Over 5k for a bunch of fans in my home. I WILL NEVER REFER ANYONE TO THIS PLACE! Contacting my lawyer and will have my day in court if necessary. BUNCH OF SCAM ARTISTS IF YOU ASK ME!"

Licensed Master Plumber with over 20 years experience in all aspects of plumbing. Since 2007, the purpose and mission of Ready Plumbing has remained the same—to provide exceptional service with integrity and professionalism and to build longstanding relationships with our customers. No matter how small or how big the job is, we strive to complete each project in a timely-manner with an unmatched level of quality, competitive pricing and customer satisfaction.

"Work That was needed: Installation of sump pump in crawl space in order to remove water in crawl space. Estimate of $1665 was sent via email on 4/4/2024. Details were not presented on the invoice, but Mr. Dye with Ready Plumbing assured us that the final invoice would have details of work that was done. ½ payment was made prior to work starting and remaining ½ was made upon completion of the work. Work was completed on April 11. Unfortunately, we were not able to physically go under house and examine the work. Mr. Dye assured us that he would send pictures and the final invoice would detail the work done. A few days after the installation my husband was forced to go into crawl space because of an issue with the furnace and was able to see the work that was done. That is when we saw the work that was done. On April 16 we sent an email to Mr. Dye with our concerns. Portion of the email is listed below: We would like to discuss the sump pump installation that you did at 80 Princeton Trace. After examining photos of the work and making a physical examination of the actual area we have identified several areas of concern that need to be corrected. • The pump was placed in a bucket and should be placed in a sump basin with the appropriate lid. The paperwork for the pump (that Mr. Dye gave us) had instructions that detailed that pump should be placed in a basin with top. • The dirt that was dug out for the pump pit should be removed from under the house. • Surface in the crawl space should be graded so water would flow to sump pump pit (which should have been lowest part of the crawl space.) Plastic covering should be replaced (if possible). • Some type of peat gravel should be placed in the bottom of the sump pump pit. Mr Dye refused to make any corrections or discuss how we could come to any agreement without more funds."

"I am leaving a review before the work is even started. I received a quote from another company and scheduled the work. When they showed up, they tried to triple the cost. I told them to get out of my house. I then called Rooter Pro Plumbing to come out and give me a quote. Jerimey Jackson came out and looked over the situation and then put me on a conference call with the owner. They agreed to match the quote I received from the other company even though it was seriously underbid. They are a great company to work with. They are scheduled to come out this week to start the project. I would highly recommend a company with such integrity in the employees and the owner. I look forward to working with them."

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.
