"After a phone call with a representative that called me and discussion of the work I was looking for, and mentioning a number of times the work involved a site visit was scheduled. When the service person came to do an onsite evaluation, I was told: 'we don't do oil tank removals and installs.' Representative was obviously not trained for what I had requested during our phone conversation and that Nicholson Heating, Cooling, Plumbing and Electrical didn't do this service or wasn't informed of it during training."

"Peter was incredibly responsive.  He responded to my initial email within a couple of hours. I received quotes from 2 other plumbers for the work and all were about the same price but Peter was by far the most responsive and professional.  He gave me a 1-hour window from 11-12 and showed up right at 11:30.  He took the time to answer any questions I had about the permit / inspection process and operation / maintenance of the new water heater.  He will definitely be my go-to for any plumbing needs in the future.

"At first it was suggested that the whole commode be replaced, but it was found out that the bowl was intact and that only the tank be replaced. This replacement was done and the new unit worked fine and nothing else was needed to be done. Great service, good workmanship and will recommend this company to others."

"Very knowledgeable and friendly. Most importantly, I didnâ t feel as though I was being pressured into repairs or services I didnâ t need. If your looking for an honest company I recommend having S&G look at any septic problems orTitle V you may need."

Septic Tanks FAQs, answered by experts

There are many reasons you may want to extend the depth of an existing well or drill a new, deeper well on your property. A deeper well can tap cleaner water sources—shallow water may contain more contaminants. With a deeper well, you’ll also have an easier time reaching the water table depth (the level at which underground water is found) and can get past tricky soil conditions. 

Plus, if your local building code requires a minimum well depth for safety and environmental standards, you’ll meet the code by digging a deeper well in the first place.

Septic tanks naturally have bacteria that break down some of the solid waste in the septic tank. However, sludge buildup is just part of owning a septic system. While liquid wastewater can be filtered and treated through the system, a septic tank company has to pump the septic tank out at least every few years.

The depth of your septic tank has nothing to do with its size. In fact, some septic tanks can even be installed above-ground! Like other sizes, a 1,000-gallon septic tank could be buried as shallow as 4 inches below the ground or as deep as 4 feet. It all depends on your specific property.

If there’s a problem with your sewage system, you might notice water pooling on the ground around the tank, which could indicate an overflow. Clogged and sluggish drains or foul smells coming from your plumbing are also signs that there might be a blockage in your septic system.

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.
