"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

Yes, a septic tank riser can replace a concrete septic tank lid. Risers are designed to replace various types of septic tank covers, including concrete, metal, and fiberglass, to provide easier access for pumping and repairs. While a plastic riser makes future access more convenient, the initial replacement can be difficult because concrete lids are very heavy, so it is a job best left to professionals. Once installed, you will need to be cautious around the riser during yard work, such as mowing, to avoid causing damage.

The best times of year to pump or empty a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access, and any snowmelt or rainfall can aid in proper drainage. Pumping before summer is also ideal to avoid conflicts with vacations or outdoor gatherings.

Fall is another great option, as contractors may be less busy than in the spring. Servicing the tank in late fall or early spring can also reduce the risk of overflow from extra precipitation during winter and spring.

While summer is a possibility, winter is generally not recommended. The ground is often frozen, which can make it difficult to access the tank, and the waste inside may also be frozen.

We’ve explained how deep-rooted plants can damage a septic tank from the outside, but plenty of things can ruin it from the inside, too. For example, flushing bulky items (like paper towels, diapers, and wipes) can clog your septic tank. Cooking oil, grease, and household chemicals can also harm your system. And since a new septic system costs between $3,460 and $11,450, it’s worth following these guidelines.

While homeowners connected to a municipal sewer line still have to keep up with plumbing maintenance, the downside to a septic system is that all the maintenance falls on the homeowners. Not calling in a pro to pump the tank every few years or accidentally flushing or draining the wrong types of materials can quickly cause clogs, which can back up into drains around the home.

A cistern works by collecting rainwater from your gutters and downspouts and storing it in a holding tank. The holding tank can be installed above or below ground, and the size will depend on your household needs. The stored water can then be used for household tasks, watering your garden, and even for drinking water.
