​Don’t let your septic tank get full! Septic systems should be pumped every 1-3 years depending on the usage of the system. ​


Septic system inspections are required by Massachusetts state law when any property is sold.


Our technicians can install risers to eliminate digging costs and repair or replace any part of a septic system that needs it.


Septic Pumping

Septic system pumping and maintenance is like changing the oil in a car, if proper maintenance is performed then the lifetime of the system is tremendously extended. Septic systems need to be pumped out every few years to make sure the system continues to function. Neglecting to pump the tank can result in an overfull tank creating a foul septic smell in the yard and septic can back up into the home. The worst result is a failing septic system due to a clogged soil absorption system.


Homeowners should pump their septic tank every 1-3 years depending on the size and usage of the tank.


Business owners should pump their septic tank yearly depending on how busy business is and you can trust us to determine that!


Septic tanks with filters provide a screening device on the outlet pipe to prevent solids from clogging the leach field. Filters need to be cleaned yearly.


We analyze every septic system and make a specific septic cleaning schedule to maintain a healthy system and evnrionment.


Title 5 Inspections

The state of Massachusetts requires homeowners to have a licensed title 5 inspector perform an evaluation on the septic system before sale of the home. The inspection process consists of determining the condition of the septic system by examining the tees, water level, scum and sludge amount, in both the septic tank and the distribution box. The structure of the septic tank and distribution box are inspected for corrosion. Lastly, we check the plumbing in the basement for leaks and determine ground water to make sure drinking water and the environment is not being contaminated.


Our Certified Title 5 technicians follow a process perfected over 57 years by the family to analyze every situation accurately.


For any problem that we encounter we always provide the most effective solution at the cheapest possible price.


We can inspect any property with a septic system. We can dig, inspect, and replace the grass in the yard so it is in great condition for sale of the property. Call us, ask us!

Grant’s was amazing! We called them because there was a problem with our system and they were at our house within the hour. Their techs were extremely friendly and explained everything for us. Their pricing was competitive and when they were done they patched our yard so you didn’t know they were ever there. I would highly recommend them. Local business and great service.

These guys seriously saved my day today. Our plumbing backed up on Friday and I called Grant’s in a panic and their CS rep was so sweet and friendly. The crew came to my house right after completing a job, helped my fiancé dig out our septic, pumped it, cleaned our filters, found and fixed the issue. They were incredibly kind, professional and went above and beyond for us. I can’t say enough nice things. They will be our septic company going forward, and I also called my mother and suggested she make the change as well. Thank you so much Grant’s!
