Thank you for choosing Certain Curtains. With the right care, your curtains and blinds will continue to look beautiful and function smoothly for many years.
Most curtains can be machine washed on a cold, gentle cycle.
Curtains with blockout lining require extra care, as the rubber backing is delicate.
If your curtains are too large for your washing machine, a laundromat with larger machines can be used. Alternatively, curtain cleaning services that clean curtains while they hang are also suitable.
Once washed:
Wave curtains rely on evenly spaced hooks to maintain their shape. The sections between hooks should alternate:
The first and last sections should face forward.
When blockout curtains are hung behind sheer curtains, you may have more hooks than runners. Rehang your curtain with 2 hooks to 1 runner. The hooks that should go to the same runner are closer together on the curtain.
Roman blinds can be machine washed if necessary:
To keep your curtains gliding smoothly:
If you are painting, sanding, or doing renovations:
Blockout and coated fabrics carry a specialised backing that behaves nothing like plain cloth. How long it lasts depends heavily on UV exposure, heat, moisture, ventilation, cleaning method and daily use — a sunny west-facing window is a far harder life than a shaded bedroom.
This means a blockout lining cannot be compared directly with an uncoated curtain or lining of a similar age. Two curtains bought the same day, hung in different rooms, will not wear the same way.
Where a fabric, blind or component comes with its own care instructions, those take precedence over this page. Textiles genuinely are not interchangeable, and the maker knows their own product best. Keep any care label or leaflet supplied with your order — and if you can’t find it, ask us and we’ll send it again.
“Something’s wrong with my curtains” usually turns out to be one of these, and they are not the same thing:
Telling them apart matters, because the cause decides the fix. Send us a photograph and we’ll tell you which one you’re looking at.
If you notice unexpected deterioration, delamination, stitching coming apart or anything else that looks like a fault, please contact us promptly, with photographs. Early is always better: we can look at it while the cause is still visible, and while something can still be done about it. Eighteen months of the same problem is much harder to help with than eighteen days.
