"Everything was fine. Responsive to texts/calls, flexible with times and unexpected need to reschedule. Friendly , knowledgeable and answered the questions I had. Other than the price ( $350 for a 1500 gal tank) which seemed a bit steep, I’d use them again. Granted, it’s been several years since last clean out, so like everything else, I suppose the rates have gone up"

"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."

"Barrows Contracting did an exceptional job on a complete replacement of our existing septic system. Glenn and his team were extremely professional and considerate throughout the process. They had a tight area to work in and they were able to take down a large tree and preserve a stone wall saving us time and money. They ran into ledge when installing the new larger tank. No problem, they were able to split the ledge and remove it the next day. The finished yard grading looks better than before the project started. They were on time and on budget, true to their estimate. This is a large ticket project and I would highly recommend Barrows Contracting for any septic repair or replacement needs. I like that they are a locally owned family business."

"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."

"My existing toilet was a pressure assist type and needs a high level of water pressure to work properly.  I had a water pressure tank installed 20 years ago to help overall and for this toilet.  The tank  that I have had stopped working.  Peter came over and tried to fix that tank but determined that it was not repairable.  The water pressure has improved in Bellingham since I installed this tank and it is no longer needed.  We then decided that the easiest and cheapest way to solve my problem is to simply install a new toilet.  Peter gave me some advice on what toilets to look for and we scheduled a time for him to come back out and install the new toilet.  
He arrived a little early for the installation and it took him and his assistant about 45 minutes to remove tho old toilet and install the new one.  They were very professional and worked quickly.  When they were finished they left the place very clean; you wouldn't know they had been there. 
I would recommend them and I would use them again.

Septic Tanks FAQs, answered by experts

Digging a well can cost between $20 and $25,000, depending on your needs. If you’re looking to dig a well yourself, all you need is a shovel. If you’re looking to have a well drilled by a professional, you can expect to pay around $15 to $30 per foot. The total cost of drilling a well will average to $5,500.

The best bacteria to add to a septic tank is anaerobic bacteria, which doesn't use oxygen to break down solid waste. Because there is less oxygen in a septic tank, anaerobic bacteria can decompose sludge in a sealed environment. On the other hand, aerobic bacteria need oxygen and are prevalent in the leach or drain field of a septic system.

Perc rates vary dramatically, and a good perc rate could be anything from 5 minutes per inch of drainage to 60 minutes per inch. The lower the number, the faster your system will drain and the more effective it will be. A 60-minute-per-inch drain rate is the highest number considered to be good, or even allowable, draining.

A septic tank lid is often 1 foot underground, but it could be just 4 inches from the surface or 4 feet deep. For septic tank lids that are closer to the surface, you’ll have an easier time locating them just by looking for signs in the yard or using a metal probe. But for septic tanks that are buried deeper underground, you’ll need to hire a pro with specialized equipment to track down the lid without risk of damaging utility lines.

You can put yogurt in your septic tank, but it will not increase the bacteria in your septic tank. In other words, it won't harm your tank, but it won't get rid of a septic smell or boost the performance of your septic system. While yogurt contains helpful bacteria, you would need to buy an extraordinary amount of yogurt to make any difference. Adding yogurt is not a helpful or cost-effective strategy.
