From MVHR in a new extension to a TR19 clean for a takeaway, work in Carshalton starts the same way: a clear look at the building and a written price before anything is fitted.
In many Carshalton homes the first step is better extraction in the kitchen and bathroom. If the windows still stream after that, a PIV unit or continuous fans usually finish the job.
Food businesses, offices, workshops and schools in Carshalton each have their own ventilation duties. We explain which ones apply to you and keep the paperwork that proves it.
