Swapping out tired timber or steel windows and doors for aluminium, sized to the existing opening, without touching the surrounding brickwork.
Most timber and steel window or door replacements don't need structural work — the new aluminium frame is fabricated to match the existing opening exactly, so we can remove the old unit and fit the new one in the same day, with minimal disruption to the surrounding wall.
What "replacement & retrofitting" means when Bluminium quotes it.
The same process whether it's one window or a full-house upgrade.
We measure the existing opening on site and confirm the new frame will match it exactly.
