Condensation Mould High CO2
Poor air quality due to poor ventilation leads to Condensation-Mould-High CO2 – Which in turn results in a high risk of health issues, spoiling of decorations and personal items
Do you ever stop and think about the air quality in your home, the air both you and your children breathe. Poor indoor air quality effects health, excessive humidity (water vapour) along with high CO2 (Carbon Dioxide) levels can result in mould growth, condensation, headaches which are associated with a range of other health problems. We are living in the 21st century, yet we are still living in damp, mould infested homes, why ?
Most of the homes we live in were constructed in the 20th Century with open fires, which ventilated the property by drawing the moisture up the chimney, this in turn pulled dry air into the property, through the timber window frames and subfloor ventilation, this natural ventilation was referred to as draughts.
No one wants to live in a cold draughty home, why should you, energy costs are high and you want your home to be comfortable, dry and well presented, this is perfectly acceptable, times have moved on, insulation as become much more efficient and is installed free in some cases, windows are sealed tight to prevent draughts, ceramic tiles, laminated floor coverings, close fitting carpets, vinyl wallpapers are pleasing to the eye.
But is making our properties airtight good for us ?. This is not as simple to answer as you may think, both humans and animals need to breath good quality air, most people will agree the air always feels fresher outside. This being due to the fact, its not loaded with CO2 , excess moisture and other pollution to the levels trapped within our homes, which leads to health issues and increases the population of dust mites

- So why are we still getting mould and dampness issues within our properties?
- How far would you get if you went for a run, with a polyethene bag over your head ?
There is no reason why you shouldn’t have the dry warm comfortable, well presented home, you want and deserve, this is easley achievable by simply installing an effective and correctly balanced and commissioned ventilation system, there is a wide range of mechanical ventilation systems out there, its not as simple as installing an extraction fan, we understand how they work and how they should be installed.
We have invested both time and money in researching the indoor air quality problem. We’ve attended courses and passed exams in ventilation methods and systems. We are bpec qualified domestic ventilation engineers, we work closely alongside Nuaire manufacturers of advanced ventilation and air purity systems and are able to design, install, commission and test the ventilation system in your home.
Nuaire are one of the world’s leading manufacturers in ventilation systems, they are the experts on equipment and the systems they manufacture, this combined with the experience of our specialist qualified surveyors and our added knowledge of buildings, building materials and how excessive moisture affects a structure, will ensure the right system is chosen, based on a detailed site evaluation.
A survey will collect the required information, to establish the cause of the dampness/poor air quality, and take into consideration :
The size and layout of the property.
Number of bedrooms
Number of wet rooms (Bathrooms, kitchens, utilities and WCs
Back ground ventilation
Heating system and method of operation.
Legal requirements- approved document F building regulations
On the 1st October 2010, to install domestic ventilation systems, which can be tested and adjusted became ‘notifiable work’ requiring installation engineers to be trained and registered to test and commission ventilation systems installed in domestic property.
For mechanical ventilation systems installed in new dwellings, airflow rates shall be measured on site and notice given to building control, This shall apply to intermittently- used extraction fans and cooker hoods, as well as continuously running systems.
Incorrect use of flexible unsulated ducting, flexible ducting should be installed to a maximum of 300mm, ducting running through cold voids should be insulated, as the warm moisture loaded air extracted, forms as condensation within the ducting, resulting in standing water and a risk of legionnaires disease and failed fan units.
Incorrect use of flexible ducting results in the system becoming restricted or separating at the joints, this results in reduced performance and high relative humidity levels forming within roof voids, leading to condensation within the property.
