If you have an issue with condensation, mould build up or ventilation issues then envirovent are the company to go to. I have been using their services for 10 years and have had a number of my rental properties surveyed by envirovent where they come up with a solution to eradicate mould issues by creating extra ventilation methods or better ventilation.
Landlord in Croydon
We have suffered condensation mould and running water on our windows for over 40 years. We have tried numerous products to remedy this and never really succeeded. In a matter of days of having this system fitted our problems have been solved. Really pleased. Great service, a brilliant system couldn’t ask for anymore.
