"Tim Haigh was great to work with at our inspection. Tim was very thorough and patient, answering all the questions I was bombarding him with. Tim never made us feel like he was rushing the inspection. For a city boy moving to the country, I know nothing about wells and septic systems. Although I was doing my own research, Tim was very helpful explaining how both systems work and recommending improvements for both systems. Tim examined every square inch of the home. He crawled into the attic, both the house and pole barn. He climbed to the peak of the roof to check the vent caps. He thoroughly stressed both well and septic systems. Tim made the inspection feel like a guided tour of our new home-to-be. At the end of the inspection, Tim reviewed all the photos he took during the inspection, pointing out the few minor issue that we would address once moved in. The inspection report we got the next day was very complete. It included all the photos Tim already reviewed with us. Everything in the report was very detailed, making us very confident about the purchase we were about to make. When the well water tested positive for bacteria, Matt Haigh calmed my nerves. Matt took the time to explain the test results to me, that the issue was treatable and not a deal breaker on the home purchase. Matt explained all the steps that would be taken to correct the issue, which the seller paid for. Weatherstone was great to work with and I would highly recommend them to my friends and family."

"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

"Kase did our new home inspection as well as the well/septic for the home we were selling. He was on time, professional and extremely pleasant to work with. When the VA needed some additional documents for our mortgage he got them right over to us (same day). And the owner and office manager were always friendly too. I would hire this company again and again."

Septic Tanks FAQs, answered by experts

Yes, septic tank companies must be licensed in most states and municipalities to perform services like installation, alteration, repair, and pumping. Since laws vary by location, it's crucial to check local requirements.

Hiring an unlicensed professional can lead to poor work, code violations, and significant fines. Always verify that your chosen company is properly licensed and fully insured to avoid liability. You can use tools like Angi’s contractor licensing search to check a pro's credentials.

It's also helpful to understand the difference between licensing and certification. A license is a legal requirement to operate, while certifications are voluntary. Credentials like the “Angi Approved” badge indicate that a business meets extra standards, such as passing a background check and maintaining a high rating.

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

Most home wells start at 100 feet, and many go as deep as 200 or 300 feet. 

It takes quite a lot of water to meet the demands of showers, toilets, faucets, and appliances like dishwashers and laundry machines, and shallow wells struggle to provide this amount quickly. If you anticipate having high water usage in the future, it’s often better to drill slightly deeper and give yourself a bit more water storage than you need.

The efficacy of a drain field depends on a wide variety of factors, though a well-maintained one can last as long as 40 or 50 years. Of the different types of septic tanks on the market, concrete and plastic tanks tend to last the longest—upwards of 40 years if they’re pumped regularly—while steel tanks have a tendency to rust over time and may need to be replaced after 15 or 20 years.

Septic drain lines (or leach lines) are typically buried between 18 and 36 inches underground, and should be at least 6 inches below the surface. These pipes are perforated and surrounded by filtering materials like sand or gravel. Burying the lines at this depth helps minimize odors and allows bacteria and other biological processes in the soil to effectively treat the wastewater. Burying lines too close to the surface can cause issues unless the soil is very compact and stable.
