About us
You deal with the person who surveyed it
Cavalli Ventilation is a family-run business in South East London. Niki has worked in ventilation since 2003 and has traded as Cavalli Ventilation since July 2019. His father works alongside him, and his son joins them when they are busy. The person who comes out and looks at your property is the person who does the work.
We are ventilation engineers first. We design, install and commission MVHR, MEV, PIV, extract systems, air handling units, ductwork, duct socks and air conditioning, across both commercial and residential work. That is the reason our damp surveys measure the ventilation rather than just recommending you improve it — it is the system we install for a living, and we can prove what it achieves before and after.
We do not do bodge jobs. Every install is left as though it were going in our own home — set out properly, finished properly, commissioned to a measured rate and documented. If it does not look right, it is not finished.
