As a new landlord and following a periodic visit to my rented property, I was devastated to find the mould conditions that had accumulated in the 6 months since it had been rented, it was severe. Being an engineer, I spent around 3 days researching typical causes and potential solutions, many of which I found relied on the habits and integrity of the tenant, which is almost impossible to control. It was at this point that my online research led me to the solutions and services offered by Grant at Envirovent. He provided me with free friendly advice, as well as a comprehensive technical insight into the 'world of mould', and following a house survey I decided upon the Whole House ventilation system. What I really liked was the flexibility of being able to buy the kit, so that with a little planning I could install it myself, and therefore save some money. For my house the results were almost instant (over the weekend); the house had a nice fresh smell and the condensate around the windows and down the walls had completely disappeared. For me as a landlord not currently living in the country, I now have complete piece of mind that I no longer have to worry about the mould coming back, and would therefore highly recommend the products of environvent, and as well the friendly competent services of Grant for anyone else facing a similar predicament. Thanks Grant!
