"I called and got a friendly greeting. 
The service call came right on time and did a nice job.
i didn't have a problem but I had never had the cesspool pumped in 22 years.
OK, it was a brand new cesspool 22 years ago and my first house so I am really clueless.
I am told to pump it every 5 years so I guess I was over due. 
Not having a clue I only had an idea of what the cost was through the phone call I had made to the company. 
I was told $485 but was charged extra for aeration , chemicals and a tube going to the over flow tank. 
In total it was $750 with my Angie's List 10% off. 
Not to bad considering I never had it done before. 
Ray & Paul were very good at what they do, professional and got me up to speed on what was going on. 
I recommend using them!

"Review for Cesspool Services I recently had the pleasure of working with Cesspool R Us for our property’s cesspool maintenance, and I couldn’t be more pleased with the experience. From start to finish, the team demonstrated professionalism, expertise, and attention to detail that made the entire process smooth and stress-free. The technicians arrived promptly, fully equipped, and ready to get to work. They took the time to explain the process clearly and answered all of my questions, which was greatly appreciated. The work was done efficiently, and they ensured that the area was left clean and tidy, going above and beyond in their commitment to customer satisfaction. What really stood out was their knowledge and thorough approach. They identified and addressed potential issues I wasn’t even aware of, which saved us from potential future problems. It’s rare to find a company so dedicated to quality service and customer care. I highly recommend Cesspool R Us for anyone in need of reliable, high-quality cesspool services. Their team is skilled, respectful, and truly dedicated to doing the job right. Thank you for providing such excellent service!"

"Positive: Professionalism, Punctuality, Quality, Responsiveness, Value The crew at Cesspool Pros was phenomenal! The boss, Joe S., answered all my questions and came to my home and walked the property with me and explained how everything would work a good two weeks before the project started. I had an older block cesspool and overflow tank and the pipe between them was collapsed and no longer working. After contacting several companies, I knew after speaking with Joe that he was the most knowledgeable and advised me the best way to correct the problem was to replace the system with a modern one rather than do a riskier pipe repair that likely would not have held long and been dangerous to do. I have a very deep septic line coming from my house, at least 9-10 feet down from the house, and even lower from the cesspool to the overflow tank. After meeting and speaking with Joe, we set a date and his crew arrived on time and spared some landscaping so it could be re-planted while excavating the property. His company has all its own equipment and they were a great team working together on the site. I stayed home to observe the process and they answered all my questions while doing the job! The install went very smooth and it is truly an interesting and awesome process to observe. They demolished the old cesspool while installing the new septic tank and then abandoned and filled the old overflow tank as per code. They then installed a new overflow system further down the property. They measured and marked all the necessary locations should any future work be required as well. They also then put all the dug up ground back down and graded the property so it could be re-seeded! Today, Joe the owner, personally dropped off the official Suffolk Board of Health paperwork to my house! All in all, I highly recommend Cesspool Pros for any septic system work! They were competitively priced, punctual, responsible, professional, and above all, they are great at what they do! Do no hesitate at all to use them!"

Septic Tanks FAQs, answered by experts

Choosing a reliable septic tank company starts by finding an experienced company in your area with positive customer reviews online. You can also use the following tips to help ensure you have a positive experience:

  • Choose a company that is licensed and fully insured

  • Ask the company for customer references

  • Ask if the company provides any guarantee for the repair

  • Determine the provider’s level of experience

There are a variety of different types of septic systems that can work in your home—such as conventional anaerobic systems, chamber systems, drip distribution systems and mound septic systems. All of them work using natural processes to break down solid waste and effectively treat wastewater without needing to be connected to a city sewer system. Which type of septic system you need will depend on characteristics of your property like how high the bedrock is or groundwater table is. Different types of systems come at different costs to install.

Age is certainly a factor in well pump failure. The older your pump, the more likely it is to fail. 

Beyond age, other factors can cause your well pump to fail, too. Things like poor water quality can cause sediment buildup in your pump. Without proper cleaning, your pump can seize up and fail. Having a dry well for too long can also cause your pump to fail, as it keeps working even though there's no water for it to pull. 

They can if they’re not installed correctly or if the caps or covers were dislodged by a lawn mower or other yard equipment. This is why it pays to hire a reputable septic tank company that’s experienced in septic tank installation and maintenance. You should also check caps and covers often to see that they’re in place and take measures to tighten or secure them, provided it is safe to do so.

The best times of year to pump or empty a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access, and any snowmelt or rainfall can aid in proper drainage. Pumping before summer is also ideal to avoid conflicts with vacations or outdoor gatherings.

Fall is another great option, as contractors may be less busy than in the spring. Servicing the tank in late fall or early spring can also reduce the risk of overflow from extra precipitation during winter and spring.

While summer is a possibility, winter is generally not recommended. The ground is often frozen, which can make it difficult to access the tank, and the waste inside may also be frozen.
