About Us


  Started by my grandfather in 1941 and passed down to the 3rd generation owner Jim McDonald. 

 We have been in business now for 79 years & counting.

Septic tank cleaning

 Theirs 2 types of people in our business.  Your "quantity"  contractors & "quality" contractors.

  The quantity guys don't care much about the job being done as they have to hurry to the next job & see how many jobs they can say they completed in a day.  

The quality contractor we don't do as much work in a day. We may not be the cheapest, but rest assured you are getting the best possible job with no corners being cut.

Sewer Injector Cleaning


Sewage pits accumulate effluent, wastewater they eject water in a sewer pipe, against the  flow of gravity.

However, if sludge or grease builds up inside the pits, it may not be  pumped out easily. This can lead to overflow and flooding of effluent in nearby areas. High volumes of debris can also  cause damage to the pumps themselves. We provide professional sewage pit cleaning taking care to avoid damage to the pumps or floats themselves.
