For anyone living in a damp or mouldy home, you may be interested in this study by one of Building Biology colleagues Lisa Coulbourn.

TELL US ABOUT YOUR EXPERIENCE OF DAMPNESS & MOULD IN AN AUSTRALIAN HOME.
Call for Research Participants Aged 18+

My name is Lisa Coulburn, and I am a PhD Candidate at Queensland University of Technology (QUT), seeking participants who have experienced issues with either condensation, dampness, water damage, water leaks, flooding, or mould in an Australian home and identify as having a mould-related illness or symptoms.

As a participant you will be asked to complete an anonymous survey either online or via a downloadable pdf. You will be asked questions about this home, issues with dampness and/or mould in this home, and how these issues may have affected your life in terms of your health and economic wellbeing.

The survey may take between 40 and 90 minutes to complete but may take longer depending on your level of health. The survey can be saved and completed within your own timeframe.

Participants will have the opportunity to enter a draw to win 1 of 20, $50 Coles e-vouchers to acknowledge their valuable contribution. The prize draw and survey will run over 3 months and close on the 20th September 2021. Participation in this study is entirely voluntary.

To volunteer or for further information, please click on the link to complete the following screening questionnaire:

Please also feel welcome to share this information with others who may like to participate.

Please note that this study has been approved by the QUT Human Research Ethics Committee (approval number 2000000980).

I am planning a trip to Canberra the 2nd week of August, so if anyone is in the ACT region (or on the way such as the Southern Highlands) and wants an assessment then email me via my website. I like to group a few clients together so the travel costs can be shared. www.buildingbiologysydney.com.au

I just wanted to let people know that I am still undertaking home assessment, however under somewhat stricter conditions due to COVID-19.

• Assessments cannot be carried out in the home of those self-isolating due to international travel within the past 14 days and those self-isolating due to contact with COVID-19.
• Prior to your assessment we will go over your concerns, the questionnaire and any test results on the phone to limit in person contact time.
• Conversations will be conducted outdoors, maintaining at least 1.5 m between parties and I will wear a face mask.
• For the internal inspection I will wear a full-face respirator, disposable coveralls and disposable gloves. I will put these on before entering your home. Conversation is somewhat tricky in a full face mask so we can talk at the end of the assessment about any findings.
• I will not wear shoes in your home – this is usual practice.
• I will use hand sanitiser before and after each assessment – this is new as I am not a fan of hand sanitiser under normal circumstances.
• Equipment will be disinfected (as much as practical) between assessments.

New pre-purchase / pre-lease service.
Increasingly I am asked to look at a property as part of a client's leasing / purchasing decision making. This is particularly important for clients who are moving from a mould affected property and are suffering from CIRS or other environmental illnesses. I have to say that I much prefer to look at a property before someone leases or buys to give my professional opinion regarding whether it is a good choice. If my clients decide to go ahead with a property where I have done an onsite assessment, I can then make recommendations to implement before they move in. More importantly I can potentially stop people from making poor decisions, saving much heartache, health issues and money down the track.

It can be very expensive to do an onsite assessment of every property that you are interested in, however, I can often tell by looking at a listing if it is worthy of an onsite inspection. Therefore, I am offering an affordable online listing investigation based on the following criteria: risks for mould & moisture; risks for traffic related air pollution; risks for elevated EMF from powerlines (not internal); potential EMR from mobile phone towers (the actual exposure can only be accurately assessed by an onsite assessment); Environmental chemical exposure risks. I can also help people outside the Sydney area with this service.

It should be noted that there are many factors that cannot be accounted for in an online investigation and it does not replace an onsite inspection. This is a cost-effective way to w**d out any properties I would consider a no-go. If you are interested in assistance regarding leasing or purchasing, then go to my website and email me via the contact page.

A tip for when it is hot and humid - turn on the air conditioning. Not only will your home feel more comfortable, it will reduce both relative humidity and absolute humidity levels. Dust mites thrive in relative humidity above 50% and mould thrives in relative humidity above 70%. So for those suffering from allergies and asthma turning on the A/C can increase comfort on several levels. If you are considering putting in A/C please make sure you don't get a unit that is too big for the area as it can lead to issues as the unit will cut out before it has stripped the moisture from the air and you can end up with condensation issues and a mouldy A/C unit.

I hope everyone has managed to stay safe and dry after the weekend of heavy rain in Sydney. Check that carpets at windows and external doors are dry. If they are wet then make sure you get as much water out as possible, and then use heating and dehumidifiers to dry them out - it helps to lift them up from the floor. If it is a large area then call in a professional to dry them out. Remember if carpets don't dry out within 48 hours then mould can take hold and you will not always see it from the top of the carpet. If the smooth edge is stained or has mould on it this indicates that you have had water ingress in this area on a previous occasion and should change the carpet and smooth edge (see photos).

Christmas is my time for a digital detox. The kids are home and after we get through the craziness of Christmas we will have a host of new board games to play, family and friends to hang out with and beaches to relax on. If you have a question look at the FAQ's on my website. www.buildingbiologysydney.com.au
I will check in again at the end of January when the kids are back to school and I can put my work hat back on. Wishing you all a safe Christmas and a healthful new year and thank you for your support in 2019.

Tips for when you go away on vacation.
1.Turn ceiling fans on to keep circulation going
2. Run air purifiers on a low setting
3. If your home is prone to dampness when it is shut up I would set up a dehumidifier with a drain pipe fixed into a floor waste (make sure it can't pop out) and set the dehumidifier to 50%.
4. Leave wardrobe dehumidifier's (small, low heat, heating bars) turned on all the time to keep wardrobes warm and dry.
5. Turn water off at the mains so you don't have to worry about burst pipes - this can be due to braided water pipes below sinks or even the water pipes to plumbed fridges bursting. Since 20% of insurance water claims are due to burst pipes (often when people are away) it is a great habit to get into.
6. Leave a key with a neighbor, relative or friend so that they can check your home after a heavy storm. Make sure they check carpet at windows and doors as well as the ceiling for potential leaks. If carpet is left wet for more than 48 hours is can quickly grow mould.
7. Take your home insurance details with you in case you need to lodge a claim or get advice.
8. If you have subfloor ventilation make sure it is turned on.
9. Keep internal doors and wardrobe doors open to encourage air flow.
10. If you have rooms that are prone to mould or musty odours, consider installing an extraction fan that draws in fresh air and can operate when you are away.
Have a happy and safe holiday period.
