Engineered for precision
- 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.
