        Delivery

        Q: Can I collect my order?
        A: Yes you can!  A “Ready for Pickup” email will be sent to you when you order is ready to be collected.  Please click this link for the Click and Collect details.  Note:  this Collection Centre is in Preston Victoria, NOT Prestons in NSW. 

        Q: When will my order be despatched?
        A: Generally, your order will be despatched within 2 to 3 business days.    

        Q: Will my order be tracked?
        A: Yes!  When your order is consigned, you will receive a tracking number that will show you where your order is and its expected delivery date.  Track your order here

        Please note: Orders with two or more items may arrive in separate parcels with no additional shipping charge

        Q: When will my order be delivered?
        A: Your order will be delivered by a specialist courier that specifically handles oversized items that cannot be delivered via Australia Post. 
        Please note that this is a specialist courier NOT an express courier. Our experience with specialist couriers varies depending upon the delivery location.  Clearly delivery times will fluctuate at peak shipping times such as Christmas, end of financial year and the pinnacle of winter bleakness!

        Q: Authority to leave?
        A: The standard courier delivery option is "Authorised to Leave". That means that if there is no one home when the courier arrives, your order will be left at your address. If this is not appropriate, please advise when you place your order for alternative arrangements to be made.

        Q: What happens if my order is damaged in transit?
        A: Our freighters have very strict policies on the ability to claim on insurance if your order arrives damaged.  There is a 48 hour window of receipt of goods for ecoMaster being able to advise the freighters of a damage claim.  PLEASE ensure you have advised us IMMEDIATELY if an order has been damaged on arrival.  Open your order immediately and check.  Outside of the 48 hour window, we are unable to make an insurance claim. 

        Q: What happens if my order gets lost during transit?
        A: Occasionally we have had orders go missing. ecoMaster has solid procedures in place and photograph every order that leaves our warehouse.  If a delivery date appears to be beyond expectation, we will raise a query on your behalf.  If your order cannot be found during transit, we will send a replacement.  

        Q: What happens if my order is stolen after delivery?
        A: If your order is stolen from your home after delivery, please raise a Police report. 

        Q: How do I make my freight costs cheaper? 
        A: We hear you!  Oversized items are expensive to transport.  Any item over 1.5m long carries an additional $10 charge by the courier.   

        Potential cost effective freight alternatives are:

        • Share the costs of freight with a neighbour
        • Buy all your long items (such as Draught Dodgers) in one order (a second tube going to the same address is free)
        • Collect your order from Preston Victoria 

        If you live regionally or in a rural location, freight costs will be high.  Do you have an address in a town where your order can be safely delivered?   We also live regionally and understand the frustration with the high costs of freight!!

        FAQ

        Q: I’m not really sure how or where to start?
        A: That is no problem at all. We have a series of ecoMasterClasses on just about every topic of energy efficiency. All the information is totally free. Click here to check it out.

         Q: What does Cavity Sliding Door Draught Proofing Kit do?
        A: Cavity Sliding Door Draught Proofing Kit will help seal one side of your cavity sliding door. In order for the kit to be effective, the door must be closed. 

        Q: Are Cavity Sliding Door Draught Proofing Kits easy to install?
        A: Draught Dodgers for Cavity Sliding Doors are relatively easy to install. There are a number of steps that need to be undertaken in sequence - which is why we provide the 7 video series.  

        Q: Do I have to use the fitting packer? 
        A: Yes. It must be used to install the head and the latch side of the kit. The fitting packer has been provided to ensure the moulding is fitted exactly the right distance from the face of the door. Not using the fitting packer guarantees an inferior result.

        Q: How do you install Cavity Sliding Doors Draught Proofing Kit?
        A: Please watch our video series under the “How To” tab.

        Q: Do you have a recommended installer for the Cavity Sliding Kit?
        A: A recommended installer is highly location dependent. To find out if we have a recommended installer in your area please contact us here or call 1300 326 627.

        Q: What is the Cavity Sliding Doors Draught Proofing Kit made of?
        A: If you choose the Raw Timber Cavity Sliding Kit, the mouldings are made from a high quality hardwood timber (Tassie Oak) as well as vinyl for the seals, flexible PVC, and an extremely durable adhesive tape. If you choose the White Cavity Sliding Kit, the mouldings are made from white powder coated aluminium. 

        Q: Can I get a sample?
        A: Unfortunately, we do not have samples of the Cavity Sliding Door Draught Proofing Kit.

        Q: Can I get different coloured seals in the standard kits?
        A: Yes, you can. However, there is a custom charge applied to make this change. Simply add your Cavity Sliding Kit to your cart and also add a Custom Charge. Prior to completing your transaction there is a notes section. Please write in this area what colour seals you would like to purchase with your kit.

        Q: The mouldings are stuck in the wrong place, now I can’t put the seals in.
        A: Unfortunately that is quite problematic. We provide installation videos to ensure a quality result. The mouldings can be removed from the door, but the self adhesive tape will not restick. You can fix the mouldings with nails or brads, make sure to use the fitting packer and watch the installation videos first.

        Q: Will the Cavity Sliding Kit help to reduce noise?
        A: Although not acoustically tested, our clients have reported significant reduction in noise after installation.

        Why is draught proofing my doors and windows so important?

        Even small gaps around your doors and windows can let in cold draughts, hot air, noise, and dust—making your home less comfortable and more expensive to heat or cool. Sealing those gaps is one of the easiest ways to improve comfort and lower your energy bills.

        Can’t I just go to a hardware store and buy a seal?

        You can—but choosing from thousands of confusing options can be a frustrating guessing game. Get it wrong, and the door won’t close, or the seal won’t work. We’ve done the hard work for you with a curated range of high-quality, expert-tested products—so you get it right the first time.

        Will sealing just a few doors or windows really make a difference?

        Yes! Even fixing just one leaky door or window can noticeably improve the comfort of your home. You don’t have to do everything at once—just start with the worst offenders and build from there.

        How do I know which product is right for my home?

        That’s where we’ve made things simple. You can use our Find and Fix My Draughts tool to quickly identify the right products for your doors, windows, and gaps. Or explore our handy kits and guides tailored to different home types and draught problems—no guesswork needed!

        Are these products DIY-friendly?

        Absolutely. Most of our draught proofing solutions are designed for easy DIY installation, and we back them up with clear instructions and how-to videos. If you'd rather not DIY, contact us and we’re happy to refer you to a trusted draught proofing technician in your area.

        Excellent product with premium finish

        The product is very easy to install and in my case makes the sliding door look finished.
        The door not only closes properly without wobbling, the reduced draught and noise makes working in the office so much more comfortable.

        Works as described

        Great product although, like some others, I would suggest adding written instructions to complement the videos.

        Hi Andrew,

        Thank you also for your suggestion about providing written instructions to complement our instructional videos. We will definitely take this into consideration and work on improving our product instructions. We appreciate your feedback.

        A great product!

        It's well described and the videos are really helpful. I'm very pleased with the kits I've installed.
        My only suggestion is to offer the white RP17 option too.

        Thank you for your feedback Linda. We're constantly striving to improve our customers experience, so we'll definitely take your suggestions into consideration.
