"Andrew did a great job fixed my upstairs toilet, had other plumbers try to figure out why the toilet wouldn't drain, Andrew used a camera in the main drain and found the problem. Awesome job, we are all set with the toilet and he checked the whole house for any other issues. We will use Andrew in the future, we highly recommend his services."

"By Andrew v. Engineer Dave Schofield of Capstone displayed professionalism by turning a flawed design for our Sudbury septic system into one highly adaptive and functional. He was purposeful about doing the right thing even when not winning installation contract, execution of which he in in fact supervised. In a business which includes its share of uneven performers, Schofield’s competence is a stand-out."

"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.

"This story begins long before we bought our dream condo, when some fool decided that an ejector pump system would be the best way to deal with our below-grade kitchen. Our troubles began once we moved in -- 3 years ago-- and began cooking regularly, the way one does when trying to eat well and not go out all the time. The pump backed up constantly, flooding the hallway and leading to amazing fungus sprouting from the wall. We called many different plumbers, most who refused to help, given the strangeness of our set-up (these pumps are almost never used in a kitchen, but typically for bathrooms or septic systems). We had some plumbers come out who I will politely avoid naming, who charged us for work that didn't do any good... eventually we got to the point where we could not use the kitchen sink or dishwasher without first checking the pump, as at any time it might unpredictably overflow. This went on and on, but then Provost came to our rescue! Although it took us a few tries to coordinate a time, we finally met Russ, who sweated through FIVE HOURS of intense labor, discovering and repairing the poor workmanship of at least 2 previous plumbers, successfully re-installing an alarm system, and providing us with an enyzme cleaning system to use as well. He insisted on closing the cabinet on the whole thing, which we did with trepidation, as we had gotten used to not trusting the pump. "You really shouldn't have to touch it again," he told us. "But call me if you have any problems!" It has been 3 weeks and we have yet to call, which feels about as close to a home-ownership miracle as we can get. I will sing the praises of these guys across Boston."

"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

Since vinegar is a weak acid with a pH of two to three, it’s generally safe for septic systems. It won’t eat away at the good bacteria in your septic tank and can help break down the sludge, which is its bottom layer. However, like with everything in life, moderation is key.

Pump the tank every 3-5 years, avoid flushing non-degradable items, and address leaks promptly to extend system life.

Baking soda does very little to nothing for a septic tank, but it can help unclog a drain or clean out a garbage disposal. Rotten tomatoes and yeast are the best ways to increase the bacteria in your septic tank naturally. You can add these to your system once every three months.

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.

A shallow-well pump can pull water up to 25 feet deep. A deep-well pump can pull water up to 90 feet deep. A deep-well submersible pump can pull water up to 300 feet deep. Make sure to consult a pro to find out how deep your well is and get the right pump for your needs.
