Neil turned up on time, was professional and efficient, and did a great job of unblocking our very blocked pipes! He was upfront about pricing/cost, too. Would definitely use again.

After accidently buying a house we had not paid much attention to, we discovered the hard way that our entire stormwater system was completely shot and had to be replaced. I got Neil from InSink out and he went over it all and we decided a completely fresh start was not going to be cheap but was the best option for us. Our backyard needed to be leveled as well so we took the opportunity to put in a 5000 litre underground water tank (plumbed to three toilets) and do some extra earthworks to make the block more usable and presentable while the excavator was here. It took a few weeks and had a fair share of headaches (especially for the apprentices digging clay by hand under the house) but at the end we have a great rainwater system for toilets and garden, proper clear drains, a new outlet to the street (as the council had not record of us being connected to the stormwater), 5 concrete pits and no issues when it rains. Water no longer flows through my garage either.
It cost quite a bit more than the original estimate but we did add in the water tank (and pumping that to the toilets) and a vanity in powder room and I decided to go for concrete pits with heavier grates and we also had some roof leaks sorted so I can't complain.
