How to fix curtains – length, eyelets, blackout lining, hanging without drilling and more
At Kelly’s Blinds, we understand that even the most beautiful window treatments face wear and tear. Our London-based team offers professional solutions for floor-dragging fabric, broken hardware, or mounting on uPVC without drilling. This guide explains how to fix curtains to restore their former glory, ensuring a perfect, bespoke fit that handles the unique challenges of London homes.
How to fix curtains that are too long without sewing?
To fix curtains that are too long without picking up a needle, you should use high-quality hemming tape and a standard steam iron. This method allows you to adjust the drop of your fabric to avoid the “dust-trap” effect caused by excess material dragging across the floor. A curtain hem is the folded and finished edge of the fabric, usually located at the bottom, which provides the necessary weight for a graceful drape.
Before you begin any alterations, have you considered the fabric shrinkage rate? Most curtain materials can shrink by 3-5% during their first wash. As a trusted London craftsman, we always advise washing and drying your curtains before shortening them; otherwise, your perfectly measured hem may sit far too high after the next cleaning cycle.
How to use hemming tape for a seamless finish?
Hemming tape, often called “wonder web,” is a heat-activated adhesive that creates a crisp, professional edge without a single stitch. This method is ideal for quick repairs and DIY home improvements where sewing is not an option. To achieve a seamless finish, follow these simple steps:
- Measure the ideal clearance: aim for a clearance of 1-2cm above the floor or 5cm below the windowsill.
- Mark and fold: fold the fabric to your desired length, ensuring a recommended hem depth of 5-10cm for a weighted look.
- Apply the tape: place the tape inside the fold.
- Iron to seal: use steam to bond the fabric.
Expert warning: While hemming tape is excellent for lightweight fabrics, we have found it can struggle with the weight of heavy velvet or thick thermal-lined drapes. For those heavier materials, a professional bespoke made-to-measure curtain service remains the most durable option.
How to fix curtains with damaged eyelet rings and hardware?
You can fix curtains with failing hardware by replacing cracked plastic components with high-quality metal rings that match your pole diameter. Eyelet rings are specialized reinforcements, typically made of metal or plastic, that support the holes through which the curtain rod passes. In modern London apartments, plastic rings often seize or crack due to prolonged UV exposure from large, sun-facing windows.
If an eyelet has popped out or the fabric is fraying around the hole, it’s time for a repair. When choosing replacements, we recommend metal rings over cheap plastic alternatives to ensure long-term functionality. The following comparison highlights why professional installers prefer metal hardware:
| Feature | Plastic rings | Metal rings |
| Durability | Often crack due to UV exposure | Better durability |
| Movement | Can seize over time | Smoother movement |
Eyelet diameter comparison table
To ensure your curtains glide effortlessly, match your eyelet size to your curtain pole diameter. Choosing the correct size prevents snagging and ensures the fabric hangs correctly across the entire width of the window. Use the following guide to find the perfect fit for your hardware:
| Eyelet diameter (inner) | Recommended pole diameter | Best use case |
| 35mm | Up to 28mm | Lightweight fabrics and narrow windows |
| 40mm | Up to 32mm | Standard weight curtains (most common) |
| 50mm | Up to 40mm | Heavy velvet or thermal-lined curtains |
| 63mm | Up to 50mm | Large-scale architectural windows |
How to fix curtains for better light control and blackout performance?
Improving your light control usually requires inspecting the thermal lining for tears or upgrading the installation to eliminate light “leaks” around the edges. Thermal lining is an additional layer of opaque fabric attached to the back of a curtain to improve insulation and block light. Statistics show that 40% of blackout curtains fail to provide total darkness, often due to poor installation or lining degradation.
If your curtains are letting in light, check the reverse side. This additional layer not only blocks light but also significantly improves energy efficiency—a crucial factor for draughty Victorian terraces. If the lining is torn, it can often be patched with blackout repair tape, but for the best results, consider upgrading to high-quality blackout curtains that feature integrated light-blocking technology.
How to fix curtains to uPVC windows without drilling?
You can fix curtains to uPVC frames using tension rods or specialized no-drill brackets that clip directly onto the window sash. These solutions are essential for Londoners in rental properties where drilling into frames risks voiding the manufacturer’s warranty or violating tenancy agreements. When using these methods, keep the uPVC weight capacity in mind; most frames can safely support between 5-8kg per suspension point.
- Tension rods: these fit inside the window recess and use spring pressure.
- No-drill brackets: specialized clips that hook over the top of the sash.
- Command hooks: these should be reserved for very lightweight decorative voiles only.
Hanging net curtains on uPVC frames
Net curtains remain a staple for street-level London homes, providing privacy without sacrificing natural light. To fix net curtains to uPVC without damage, use lightweight tension wires or small adhesive “end hooks.” These are designed specifically for low-weight nets and won’t put undue stress on the window seals.
How to fix curtains with gaps and alignment issues?
To fix curtains that don’t meet in the middle, you must adjust the tension on the heading cords or increase the fabric’s “fullness.” This is often a problem with pencil pleat headings where the cords haven’t been pulled evenly.
Ensure your curtains are at least double the width of the window to provide enough overlap. If a gap persists, a professional “trick of the trade” is to sew small, hidden magnets into the leading edges of the fabric. This ensures the curtains “snap” together when closed, providing a perfect seal against the morning sun.
