Double Glazing & Safety

Window Pane Repairs
Glass or double glazing broken or misted
Broken glass can be replaced. If there is misting between the panes, not just on the surface then there is likely a failed seal that can be changed without replacing the whole window.
Child proof my windows
We fit British Standard restrictors, that limit the window openings only up to 100mm width, preventing any openings that may lead to accidental or intentional falls from upper floor windows.
Quick repair responsive service
Many of these problems can be repaired within 30 minutes. We have a uPVC window specialist who works with ASL and our sister business LBP uPVC repairs so bigger jobs like complete window set replacements can be completed quickly. We carry many standard spare parts like window hinges and window handles.
