Will I have one point of contact for my whole project?
Yes, a single point of contact tracks your project from measurement to installation, so you're never passed between departments.
How do you track my order from measurement to install?
Our project management system logs every stage (measurement, fabrication, dispatch) so you get updates without having to chase anyone.
Do I get updates during fabrication and dispatch?
Yes, you're kept updated as your windows move through fabrication and dispatch, not just at the start and end.
Is consultation, ordering, and installation all one team?
Yes, the same team handles consultation, ordering, and installation, so nothing gets lost between handoffs.
What happens after the site survey?
Your exact measurements go straight into fabrication; every unit is engineered to fit your opening, not a standard size.
Can you tailor the system to my building's exposure?
Yes, hardware, glazing, and sealing are specified to your building's sun, wind, and rain exposure, not a one-size-fits-all setup.
What support do I get after installation is done?
Ongoing support after installation, plus TEXGUARD's coating warranty covering colour and scratch resistance for up to 40 years.
What if I need an adjustment a year down the line?
Reach out any time; our team handles post-installation adjustments as part of ongoing customer support.
What does 'window-in-a-box' actually mean?
Every unit is pre-engineered at TOSTEM's facility and delivered ready-to-fit in a box, for error-free, factory-precise installation on site.
Is the hardware pre-fitted before it reaches site?
Yes, TOSTEM's pre-engineering fits hardware, gaskets, and seals at the factory, so installation is fast and consistent on site.
How do you keep installation dates predictable?
Pre-engineered, factory-assembled components and robust packaging keep timelines predictable: no on-site guesswork.
