Frequently asked questions
What causes window seals to go brittle?+
Heat, UV and age. Perth's hot summers accelerate the process, especially on west facing windows.
Can a brittle seal still be working?+
Usually not. Once the rubber loses flexibility it can no longer compress against the glass or frame, so it stops sealing.
Is replacement messy?+
We bring drop sheets and clean up every flake of old rubber as we go.
Do you replace seals on all window types?+
Yes, sliding, awning, double hung, casement and fixed windows in aluminium, timber or uPVC.
