Removing Mould From Your Bathroom

BLEACH
​Okay, so most people when they have mould problems immediately reach for bleach, ammonia or marketed products such as Exit Mould. The trouble with these products is that they simply DO NOT KILL MOULD. You see mould/fungi contain melanin which gives it it’s colour. Bleach or bleach type products just removes the colour out of the mould. So effectively, bleach just masks the mould giving you the illusion of a mould free bathroom but the mould is still actually there, alive and growing.

The other problems with harsh chemicals like bleach and Domestos is that it will harm your grout. Not only have these chemicals been known to remove the colour from grout but they will also weaken the grout’s structure. 

VINEGAR
​Vinegar is a great natural product when wanting to destroy or prevent mould growth. However it should be used with caution.

Vinegar penetrates the structure of mould and causes it to explode, which kills the mould.

The trouble with using vinegar as your go to cleaner is that it is an acid cleaner. Over time the acid in the vinegar will weaken the structure of your grout. If you must use vinegar we suggest to only use vinegar to kill mould initially, then only use it occasionally to keep mould at bay. Never use vinegar as your daily/weekly cleaner.

We approached ARDEX, an Australian grout manufacturer, about what type of cleaner should be used on grout. Here is what they had to say.

METHYLATED SPIRITS
Methylated Spirits is the all round hero cleaner for your bathroom.

When it comes to killing mould, methylated spirits works the same way as vinegar. It penetrates the mould spores and makes the mould explode. (Source: Dr Heike Neumeister-Kemp, Mycologist/mould expert).

The best part about methylated spirits is that it is a neutral cleaner. This means it is safe to use on most surfaces in your bathroom, including grout. Methylated spirits is safe to use on glass, sinks, chrome taps, ceramic, stone, marble and grout. (Do not use on painted or varnished surfaces).

Another positive about methylated spirits is that it is readily bio-degradable, meaning that it breaks down quickly and naturally. It is safe for the environment. 

To effectively kill mould, make your own methylated spirits cleaning solution with 80% parts methylated spirits and 20% part water.

​Mould is a fungus that reproduces and spreads by spores and it loves growing in damp, moist areas of your home which are poorly ventilated. The circulation of dry air retards mould growth. Hence proper ventilation will prevent most mould growth.

Here are a few things that homeowners can do to try to prevent mould growth. 

• Keep extractor fans clean and clear of fluff
• Make sure the extractor fan is on and have a window slightly open while showering/ bathing
• Don’t have excessively hot showers which steam up the bathroom
• Keep the exhaust fan running for 20 minutes after showering/bathing to remove excess moisture
• Clean your bathroom weekly with a methylated spirits solution.
• Open your doors and windows as often as possible to create good airflow
• Leave the shower door open to let the shower dry out after use

​GROUT 
Grout is not waterproof! Every time you shower, water seeps through the grout, then trickles down to the wall and floor joint.  Water then accumulates behind the silicon joint and creates a nice damp environment. Which is why the wall/floor joint is usually the first place where you’ll see mould growth in your bathroom.

Firstly, if you have a new bathroom that hasn’t been used, we suggest you seal* the grout before the very first shower. This will help to repel water from entering the grout. 
*Note: Grout should cure for 14 days before being sealed. (source; Ardex Australia)
 
If your shower is well and truly used, then we suggest you give your shower a really good clean (with vinegar) then let your shower/ bathroom dry out (yep, this is your permission to take a week off and holiday somewhere really nice). Once your shower is nice and dry seal the grout.
​
If your bathroom or shower grout is extremely mouldy and discoloured beyond repair, then your best option would be to remove all of the old grout and spray the tile joints with either vinegar or methylated spirits to kill any mould spores. Let the tile joints dry out then re-grout your tile area. 

If your bathroom has porous ceramic glazed tiles, we suggest applying a product such as Shower Plug (available Bunnings) over your whole shower area.

IMPORTANT: Follow the manufactures directions when applying the grout sealer and reapply within the recommend time frame to keep your grout sealed. 

Enjoy beach vibes in your bathroom every day with a colour scheme that emulates the soothing tones of a day well spent at the beach.

In Australia, bathrooms are one of the most popular rooms to renovate. Bathrooms are also one of the most expensive rooms to renovate and the cost will differ greatly, depending on the complexity of the work required and the level of bathroom finishes desired by the home owner.

​Every bathroom renovation is unique and the cost to renovate will depend on the following factors.

• size of bathroom
• logistics of parking and rubbish removal
• location (travel time will incur extra cost)
• position of bathroom inside the house or unit
• demolition requirements (compete/partial, asbestos removal etc)
• existing water or termite damage
• protection required for existing surfaces
• the quality and level of finishes (tiles, timber etc), fittings (handles), fixtures (tapware, benchtop etc)

 
If you want to completely strip out and take the bathroom back to its shell, repair water damaged framing, re-sheet, waterproof, bed and retile, alter plumbing and/or electrical and repaint, the average bathroom renovation cost, using quality tradespeople will be about $25, 000.

Bathroom renovations are very labor intensive. A big portion of the budget will be spent on trades.
If the tradespeople are chosen carefully it will be money well spent.
 
One of the problems encountered in the renovation industry is unlicensed and uninsured people with cheap prices, poor quality products and even poorer skill methods, portraying themselves as tradespeople.

It costs licensed contractors a fair amount of time and money every year to be fully licensed and insured. Licensed contractors are required to undertake continuing professional development every year to retain their license.  

It is important to check all credentials of tradespeople before hiring them. It would be foolish to compromise on the quality of your tiling, waterproofing, electrical, plumbing or carpentry just to save a few dollars.

Vanity Units
Cost can change considerably depending on whether you choose something off the display room floor or out of a catalogue compared to if you want a one-of custom-made piece. Also, the material type can greatly impact on price. Timber is a popular choice at the moment, however it will cost a great deal more than Laminex or two pack. Bench top types is another cost that can vary greatly. Vitrified China tops are a great choice for a low budget bathroom, stone bench top for a medium budget and timber or concrete for a high-end budget.

Tapware
Tapware is another item that can make a huge difference to your final bathroom cost. Budget tapware starts under $100 and can jump up into the thousands for high end tapware.

As you can see, it can be difficult to judge how much your bathroom renovation will cost without a detailed quote. It is important for homeowners to make sure the quotes they are getting compares apples with apples, so to speak. What is in one quote needs to be in the other quote, of the same quality and quantity for the quotes to be a fair comparison.
