Book a JobWhat Isaac’s PLUMBING customers are saying
“Can’t fault the Hastings crew, fixed a large leak on a shared driveway. Good communication, explanation before, during and afterwards. Workmanship and completion of job done in a timely manner with little disruption to house owners.”
— Raquel Jordan
“These guys are great. I had a hot water cylinder that was leaking from our second story house through a ceiling onto the floor of a room underneath. I rang several “urgent” plumbers but none could attend promptly. I then rang Isaac’s, they were at our property within an hour and did a great job at a reasonable cost. I will use this firm again if the need arises. Highly recommend.”
— Bob Bell
