Shannon and his team were very progressional and superior tradesman who completed a massive job in my house.

The work consisted of excavation, plumbing and drainage to solve the issue we had been trying to solve for years which was subterranean ground water running and pooling under my house creating a musty smell, mould and health concerns for my kids.

From the first consultation Shannon inspected the issue then very patiently worked through the various options available and the associated budgets for each option.. I felt confident and reassured throughout all the stages of the job that we were doing the right thing. Then Shannon went over and above to ensure his work would deliver the solution we discussed.

My wife and I are so happy knowing there is no pooling of water under our bedrooms, especially the kids bedrooms. The musty smell has disappeared and so has the build up of mould in the cupboards. Not to mention the health concerns having kids in the house.

They always left the site neat and tidy at the end of the day and were super friendly and respectful to my entire family.

I fully recommend Scooper plumbing for any plumbing, waterproofing, or drainage issues both internal or external.

Andrew Stanley Eastern Suburbs

Shannon undertook a project to resolve inflow of storm water to the underside of our house to prevent property damage, a full two-week job. Shannon was prepared to take on work that others may have declined in search of ‘easy work’. Shannon was always very easy to deal with and always did his best to work in with his client’s needs. He certainly appeared to gain genuine satisfaction from helping his clients to solve their problems. He was very capable and professional in the way he went about his work and he achieved a very successful outcome for the project. He cleaned up the site at the end of each day and cleaned up extensively at the end of the job. I would highly recommend Shannon to others seeking his specialised and professional services.

How To Drain Water From Under House? Solved

This is a question I get asked all the time. One of the things that you need to keep in mind is that the rock shelf varies under the ground and under the house or building.  So water can pool in some areas under the house and only when it has reached a overflow level like the top lip of a fish pond will it flow over and on to the next under ground and under the house catchment area.  Therefore it will just stay soaking in the ground where it is not welcome.  This pooling water under the house or slab whether seen or unseen will cause water damage and mould to grow if not rectified.

Many of my customers call me after they have spent thousands of dollars on under floor fans and ventilation options as well as inexperienced plumbers "in this particular field" with their little aggi drain and pit solutions. Fans are good but let me give you and example.  Let say you put the dogs water bowl out in the breezy part of the yard in full sun.  Do you think that the water will disappear? You may think yes, in time it will.  You would be correct, but it actually takes time.  Many days to even a week.  Now what if you had a very slow drip of water adding to the level every 30 mins.  Do you think you would ever evaporate the water?  I find it very unlikely.  This is also true with under the house drainage fans and ventilation systems.  It is a very hard sell for me as I see the damage and the actual flow of the water that is constantly topping up this catchment area under the house.  You will notice on some of my pictures that the water is filling up our trenches overnight.  We finish digging out 4pm and when we return in the morning to continue our work the water level is up again.

My customers have been reporting to me with great satisfaction that their pumps are kicking in 2-3 times a day.  This actually means they are removing from under their house or in most case from outside of their house before it can make it under around 150 litres per day.  This is not rain water but subsoil water only.  Water that is running beneath the surface moving undetected. This is then allowing the water under the house to dry out and even drain from under the house back to our system outside.

Mould and Rising Damp Problems

Mould and rising damp problems are something the many families have been dealing with for years in Sydney due to the fact that a lot of Sydney properties are built on a rock foundation or there has been poor storm water drainage installed originally. The water which is under the house happens either after heavy rain or from a constant flow along the rock shelf.

Many families have been alerted to the health issues and dangers of mould in the house which is caused by rising damp and water lying under the house or around the foundations of the building.

Mould has been linked with lowering the immune system and causing multiple fatigue issues and some specialist regard mould in the house as a contributor to cancers in individuals who have been exposed to a mouldy house for an extended period of time.

Many people ask “how can you remove moisture under the house”. There are some excellent ways to prevent moisture, water and off course mould by stopping the water from getting under the house and sitting around the building foundations in the first place. Prevention is better then a cure.

Stop the Under Ground Water First

We have successfully blocked the under ground water which runs along the rock line and will flow easily under your foundation and make its way to the basement room and create that mouldy musty smell. Generally the soil around the foundations is lower then the rest of the soil under the house and therefore the water pools around the foundations. This causes the water to soak into the bricks and this is called rising damp. Very often we see black mould on the walls above the foundations and especially in basement rooms or basement apartments. This can be solved by implementing hand in hand both waterproofing and drainage methods.

Catching the storm water before it can reach the walls of the house is also vital. In some cases a in the ground drainage under the house sump pump may be needed to collect the water from under the house or catch the ground water and then pump the water up to the stormwater system so it can get away from the building.

Rising damp is caused by water resting at the base of the foundations and sometimes the cost to do damp proofing can be very high but you still will have water damaging your foundations and running under the building or house. 


Damp proofing treatments are very good but they will not solve the problem of water and mould under and in the house. Preventing the water before it can effect the foundations or make its way under the building is a much better and a more complete damp mould solution. In most cases our system is only required on 1 or 2 sides of the house or building as it depends on the direction the ground water is coming from as it runs along the rock shelf. This is the best way to dry out under the house.

Mould Removal and how to get rid of black mould and damp in the walls is easy once the wall are able to dry out after our work is done and then you can scrap back the mould and that lime build up from the bricks and prepare the wall to be repainted. Before any mould removal specialist come in you need to prevent the water from causing the mould and damp problems from returning.
