Korjausompelu Helsinki
Clothing Repairs in Helsinki
Korjausompelu by Double Stitch by Sumu. Zipper replacements, invisible mending, and lining repairs at our Liisankatu studio.
A broken zipper on your favorite jacket is not a reason to replace the jacket. A tear in the lining of a coat you have worn for ten winters is not a reason to throw it away. Double Stitch by Sumu is a Helsinki korjausompelu (repair tailor) that specializes in giving clothes a second life.
Our repairs are invisible enough that most people will not notice anything happened, and our prices are low enough that keeping what you own is usually the right financial decision as well as the right environmental one.
Repairs are the most sustainable clothing choice available to you. The carbon cost of producing a new garment is many times the cost of fixing the one you already own, and the load on the landfill system is multiplied again when a repairable garment is thrown away instead. If you have a coat, a jacket, jeans, or a dress that has seen better days and you are not ready to let it go, bring it in.
What We Repair
The full range of clothing repair work, from quick zipper swaps to invisible weave repairs on heritage fabrics.
Zipper Replacement Helsinki
Our most common repair. Jackets, coats, skirts, dresses, and bags. We stock common zipper colors and sizes and source unusual ones from our supplier. Turnaround is usually under a week.
Invisible Seams Helsinki
For wool, cashmere, silk, and cotton where the fibers can be realigned and stitched so the repair is virtually invisible. A slower, more skilled repair for pieces worth keeping for years.
Hem Repairs Helsinki
Fallen hems on coats, dresses, trousers, and skirts. We rehem with the correct hand or machine technique for the garment and fabric.
Lining Replacement
Jacket and coat linings tend to fail before the outer fabric. We replace linings in full or part, matching the original color and material, or upgrading when a better lining improves the garment.
Button Replacement and Buttonhole Repair
Lost buttons, damaged buttonholes, missing closures. We match original buttons where possible or replace the full set for a new look.
Pocket Repair and Replacement
Worn-through pocket bags, especially on trousers, are very common. We replace them fully in matching fabric.
Repair or Replace: An Honest Guide
We will not sell you a repair that does not make sense. Here is roughly how we think about it.
Repair Almost Always Makes Sense
- Well-made coats and jackets with zipper or lining issues
- Jeans with worn hems, knee holes, or pocket wear
- Any garment you love and cannot easily replace
Repair Might Not Make Sense
- Fast-fashion pieces where the repair costs more than a replacement and the fabric is already failing elsewhere
- Garments with multiple simultaneous failures in already-thin fabric
- Very inexpensive zippers you could replace at home with a kit
When you bring something in, we tell you which category it falls into. We would rather send you home with honest advice than charge for a repair that will fail in six months.

Sustainable Fashion Through Repair
Repair is the most effective clothing sustainability strategy available to individuals. Buying less is first. Repairing what you already have is second. Everything else (rental, swap, resale, recycled fabric) comes after.
Every zipper we replace keeps a jacket out of the landfill for another few years. Every invisibly mended sweater is a sweater that does not get thrown away. Over the life of a good piece of clothing, routine repairs are often cheaper and always better for the environment than replacement.
Finland imports most of its clothing. Repair is one of the few things we can do locally that pushes against that footprint, and we are proud to be part of Helsinki's repair infrastructure.
Frequently Asked Questions
How much does zipper replacement cost in Helsinki?
Zipper replacement starts at €30 for skirts and €50 for jackets and coats. Invisible, two-way, and long separating zippers can add to the cost. Turnaround is usually three to seven business days.
Can you really make holes invisible?
In most cases on wool, cashmere, silk, and tight weaves, yes. The technique involves realigning the original fibers and stitching along the weave so the repair blends in. On knits and very worn fabrics the repair will be strong but visible. We assess each piece and tell you honestly what result to expect.
Do you repair jeans?
Yes. Jean repair is some of our most common work: hems and rehems, knee holes, back pocket wear, and pocket bag replacement. We can do invisible denim repair or visible sashiko-style mending as a design choice.
Do I need an appointment for a repair quote?
For simple repairs (zippers, hems, buttons) you can drop in during opening hours and we will quote on the spot. For complex repairs or invisible mending, book a short appointment so we can give the piece a proper look.
