"Replaced leech field- he did an excellent job removing my old leech field and replacing it with a better system. From the time I entered the job in homeadvisor (approx 8am) I was called back before noon. We scheduled a site review later that day. From the time I selected Roadway, there was constant progress. Even when the permits were in progress, they were in constant contact to let me know what was going on. When the permits were in order, they worked nonstop until the job was done. Their work was excellent, prompt and neat. Highly recommend."

"Worst homeowner experience of my life. Hired to replace a sewer line from my house to the street - three day job turned into three weeks - said they didn’t need to shut off our water, though we asked, then broke the water line and flooded the hole, which backed up into the broken sewer line and then back into my basement - city engineers were all over the job because of safety concerns, including a teenage boy working in a 12 foot hole with no cave in support. I doubt the city of Dover would even give him a permit again. - never worked a full day. Left early for reasons ranging from broken equipment, teaching karate lessons, or going to daughter’s events - hole was definitely not packed back in correctly as we ended up with a moat the following spring. A pizza delivery guy literally fell into the dent in my front yard. - cost of job went up 150% from original quote and he wouldn’t itemize the bill - and here we are a year and a week later and my sewer line is backed up again so the job was bunk. I’m not even kind of surprised. Dana is the worst. Stay away from this business. I will be filing complaints with anyone and everyone who monitors these types of business. Horrible."

Septic Tanks questions, answered by experts

Septic systems typically require servicing every 3-5 years, but frequency varies according to household size and tank capacity.

The most budget-friendly septic system is a plastic tank, which starts at around $2,900. This is $200 less than concrete septic tanks and $500 less than fiberglass.

It’s not needed for your septic system to operate, but it will make regular maintenance and the ability to access your tank infinitely easier. You’ll likely also save some money in the long run, not to mention a lot of labor and energy because there will be less digging involved to find the tank when there’s a riser installed.

The septic tank needs to be pumped at least every three to five years. If the septic tank is too small for the property, you might find it needs to be pumped more frequently, and during an inspection, a septic company may recommend updating your system to a larger septic tank. While 750-gallon tanks used to be standard, septic tanks with a 1,250-gallon capacity are now more common.

A septic tank lasts 15 to 20 years on average. This life span will vary depending on the type of septic system and the materials used. Clogging caused by plant roots or flooding from groundwater can decrease that life span. To avoid these issues, have a pro inspect your tank regularly and perform routine maintenance, such as pumping out the tank.
