Quality Tradesmen

With our trade knowledge and high focus on customer service we pride ourselves on being the most professional, skilled and service driven plumbers Western Sydney has to offer. 

"I am big on recommendations and I was not let down when Downstream Group was suggested.

We had what we thought was a minor issue and required a plumber to check it out. Rather than a quick Band-Aid job, Downstream went above and beyond to make sure we were all sorted without any issues moving forward.

Super kind, friendly and professional.

Thank you."
