It depends on the fault, the parts needed and access. A seal replacement is a small job while a new pump or filter costs more. Send through a quote request describing the problem.
A simple bucket test can tell the difference. If the pool drops faster than the water in the bucket, there's likely a leak.
If the motor is sound, seals and bearings are usually worth repairing. Older or inefficient pumps can be better replaced.
Most common pool equipment brands can be repaired, and parts are sourced where needed.
Electrical faults are referred to a licensed electrician where required.
