As the Authorised Channel Partner of TOSTEM in Mumbai, Selective Systems manages the entire journey of your windows and doors — from initial consultation and site survey, through TOSTEM's pre-engineered manufacturing, to final on-site installation and handover.
TOSTEM's own approach mirrors pre-engineered construction: the unit is designed and fabricated at the factory, and only the assembly of components happens on site. As roughly 90% of the work is completed in a controlled factory environment, there is no dilution in quality between what is tested and what is actually installed — the performance you're promised is the performance you get.
We carry that same completeness into our own service: one team handles consultation, ordering, logistics, and installation, so nothing is handed off between disconnected vendors along the way.
What this looks like on site.

One team, from the first site visit to the final seal.

Factory-engineered units, installed by the same team that quoted them.

Consultation, fabrication, and installation under one roof.
How we deliver it.
Consultation & site survey
We assess your openings, structure, and requirements before recommending a system — not after.
Factory-engineered manufacturing
Your order is fabricated to spec at TOSTEM's facility, where controlled conditions keep tested and actual performance identical.
Logistics & site readiness
Units are packed and dispatched as complete, labelled window-in-a-box units, minimising handling risk before they reach your site.
Installation & handover
Our own installation teams complete the fit, seal, and finish, and walk you through the finished work before signing off.
