Fix Rising Damp with Subfloor Ventilation System
Fix Rising Damp with Subfloor Ventilation System
Rising damp carries soluble salts up into the masonry, known as efflorescence. This dampness affects the quality of air that you breathe while you’re indoors. A damp home with low ventilation has air that contains pollutants which can trigger the development of asthma and other respiratory-related infections, as well as allergic reactions.
One of the main problems when homes are damp is the development of mould, usually on the wall. As a result, allergens are produced. Even if your home is clean and dust-free, you may find yourself sneezing, experiencing itchy eyes or a runny nose when you come into contact with the spores produced when mould grows from a damp area in your property from lack of air flow. Another danger associated with rising damp issues is the fact that it creates an environment for the development and multiplication of harmful bacteria such as mould.
Rising damp can be a homeowner’s worst nightmare as the building structure can be affected by rising damp. The integrity of the foundations can be seriously put at risk due to rising damp.
Another culprit for rising damp is the age of your home. Homes built before 1980 are often found with damp rising in capillary action in the brick work or masonry due to the fact that the walls were either inferior or had no damp course. The internal walls of these older homes have a more common issue with water penetration. Building regulations have since been updated over the years to include items to help prevent this problem from occurring. There is a damp treatment and solution for each reason of rising damp.
What Causes Rising Damp?
Whenever a home has a rising damp issue, the main reason behind it is usually the high levels of moisture in the air and the lack of natural sub floor ventilation. There are many situations that can lead to different house structures having rising damp and therefore creating places for mould to grow.
- Rising damp originating from the sub floor area creating moisture penetration behind the walls of older buildings or commercial properties.
- Moist building materials used in the construction of a new home can often cause rising damp to creep up the walls.
- Water leaks from water supply pipes.
- Window frames leaking or leaking roofs that allow rainwater into the home or through the walls will cause rising damp.
- Poor movement of air under the floor in the property.
- Whenever there is too much moisture in the air, it condenses back into water droplets when it touches any cold surface in the home. The walls or windows may provide this cold surface. As a result, the condensed moisture, which is now in the form of water droplets, will cause rising damp up the walls. Rising damp occurs mainly when there is inadequate air flow.
Rising Damp In the Sub Floor Area
A common area in the home that can create rising damp is under the house – the sub floor area. The sub floor area can easily harbour ground moisture, causing rising damp throughout your home’s masonry structure. Mould, usually on the walls inside your home, is a sign of rising damp. Rising damp can also cause pest problems when located at ground level. The damp conditions can be a magnet for termites who like to eat the damp wood. This occurs especially when there is insufficient air flow. A leaking pipe beneath your floor can also cause the sub floor area of your property to become damp, more so when there aren’t enough vents or a sub floor ventilation system that can facilitate proper circulation of air. Rising damp at floor level can weaken the structure of the wall. Masonry walls can begin to crumble.
Additionally, metallic material will experience corrosion, causing damage to the entire building. Rising damp is a real risk to your property, but sub floor ventilation can easily eradicate and prevent rising damp from developing. It is one of the best rising damp solutions.
- Sub floor ventilation systems are very effective in homes that experience a continuing musty odour or where there is mould on shoes and clothes in wardrobes or on furniture in living spaces.
- Subfloor ventilation can remove ground moisture from underneath raised floors, creating a drier and warmer sub floor area.
- Poorly ventilated sub floor areas are often damp. This dampness can result in mould, mildew, musty odours, wood rot and pest infestation in your sub floor area and can also contribute to the spread of mould, mildew and allergies above.
From start to finish the process to get sub-floor ventilation was seamless. Fresh Ventillation is a very friendly and professional organisation, who use quality products. From my first approach to this company to installation, all made very easy. I would certainly recommend this organisation for any ventilation issues.
We had two large bathrooms with open showers that had significant steam and moisture issues. We selected Fresh Ventilation to provide the ventilation kit, i was impressed by the quality of the product and more importantly after having post installation issues, we received excellent after sales support to resolve the issues found. I would have no hesitation in recommending Fresh Ventilation for any ventilation requirement.
I experienced excellent service and advice from Fresh Ventilation in both my recent underfloor ventilation purchases. Their help went beyond what I would normally expect from a retailer and made for an easy and pleasant experience.
After placing an online order for a 4 room heat transfer system kit with R1.5 green ducts plus a few extra bits, staff from Fresh Ventilation were on the phone within the hour. Excellent customer service. Due to logistic challenges getting the kit from the warehouse to my cold climate rural property, I was kept up to date with many phone calls, yet the process was very professional and low stress. The kit arrived within a week ands installed soon after. The product is high quality and has made a huge difference in balancing the temperature between the rooms in my home. An added bonus is a significant reduction in condensation on windows in the mornings and hence less problems with mould/mildew build up. Using a FTIR camera I can happily report that there is a 1.5C temperature difference between the intake and the furthest outlet at the other end of the house. Overall performance is exceptional and beyond my expectations. I can highly recommend.
the fan in our IXL was just not cutting it so after speaking to the customer service team (a lovely lady) I ordered their bathroom fan kit. The difference is night and day, it gets rid of so much more steam and leaves our bathroom so much drier. Its going to help the issue we have with constant dampness and mould in our bathroom tremendously.

Ordering was easy and communications about order were clear and I was kept informed. Delivery was prompt and I got my order within 2 days or ordering (I ordered on the weekend). DIY Installation was simple, side from access issues which have nothing to do with the product. Extremely happy overall. Would happily order again.
Just want to say a big thank you for the seamless installation of the DVS. It is sooooo good! I finally got to see the system on Monday after a contactless installation. We are so happy with it and can feel the difference! No condensation on the windows in the masters bedroom on cold mornings, and the temperature in the WHOLE house is uniform. We usually find the study room and downstairs to be freezing cold in the morning and find that there are no hot or cold spots in the house. What an amazing product and a great team!
Such a pleasure to be dealing with you Claire. Big thank you to the team as well for the smooth installation. In the middle of having a baby and being in hospital for 2 weeks due to post-delivery complications, it was really nice to know I could leave it in your capable hands!
From first contact my partner and I were very impressed with the way Cam communicated with us and worked with us. He always had the time to talk and the patience to explain how the system could work with our home. Cam took the time draw up a plan showing where best to place the vents and explained why the placement was best and how we could save on conduit. Throughout the installation process Cam was always prompt and clear in walking me though how to go about things from hole cutting in the ceiling, to taping conduit, to running cables down the wall for the control unit. He even made himself available on a Sunday to help with the configuration of the unit! 10 out of 10 for service!
What a breath of fresh air to work with a company that is so responsive and who actually deliver what they say they will. Cam and Claire were simply fantastic to deal with. My questions were understood first time and were answered accordingly. The items arrived as ordered, in good condition and within a very quick time frame.To all of you other businesses out there, if you want to see a great team in action, deal with this company. I have dealt with plenty of ordinary companies over the years and this team leaves them in their wake.
I recently brought EC bathroom fan kit along with underfloor ventilation kit I have to say I’m impressed with both products easy to install, quiet in operation the bathroom in line fan is so much quieter than the old in ceiling fan that just vented into the roof cavity
I recommend both these products you won’t buy better and the service is second to none
We have had trouble with damp for several years and had spoken with many professionals to try and fix the issue. Cam was the first to suggest a ERV system and explained very clearly how it would fix our issue. Cam and his team installed the system very quickly and the results were noticed from the moment the system was switched on. No more wet windows in winter and we can actually dry clothes inside now.
Would rate 6 stars if I could.
From my initial phone call Cameron was extremely helpful and professional. Cameron provided me with a plan for installation to suit my needs. Upon order the kit arrived within 2 days. I called Cameron as he requested when the kit arrived and he talked me through all of the items to ensure I knew what I needed to do to complete my installation. Cameron also provided photos of previous installations to assist me. During the installation I called Cameron a couple of times with queries and he gladly took the time to assist me. It is very rare to receive this type of support and after sales assistance. I highly recommend Fresh Ventilation for Sub Floor Ventilation Kits.
We highly recommend Fresh Ventilation, their customer service and product knowledge was second to none. Happy to take calls on the weekend and after hours to ensure a smooth install process.
Extremely happy with our Heat Transfer system, our children’s bedrooms are now nice and snug, without the expensive oil heater electric bills.
The whole process from advice, planning, purchase and installation was excellent. It was immediately apparent that Fresh Ventilation offered quality and highly specified equipment when compared to the many other self installation set ups available. I was very particular with the best and most reliable solution to my subfloor ventilation problems and the detail and knowledge of the equipment that Cameron was able to provide was clearly a class above other sellers. He provided very personalised service and was always available for further advice and guidance. Every detail of the package was quality. The motors are high end, the ducting provided was industrial spec (beyond the quality of trade stores that I have sourced previous from) and even the ducting tape was a top quality brand. I highly recommend dealing with Fresh Ventilation.
