Persian Rug Repair: What Can Be Fixed, and When It’s Worth It
Most damage to a Persian rug can be repaired by a good restorer, and the same goes for any hand-knotted oriental rug. Worn sides can be rewrapped, loose ends secured, and holes and moth damage rewoven knot by knot. A rug that ripples or curls can usually be made to lie flat again. Two problems are much harder to undo: a cotton foundation that has gone brittle from damp, and dye that has run into a neighboring color and set. Making a rug smaller is a separate question, covered in can you cut a Persian rug down to size.
Whether a repair is worth doing depends mostly on two things. Is the damage spreading, and how much does this rug matter to you?
Worn edges and ends: repair them first
The long sides of a hand-knotted rug are finished with a cord of foundation threads wrapped in wool. In the trade this edge is called the selvedge.[1] It is the first part of a rug to wear, because feet, vacuums and furniture all catch it. A restorer repairs a worn side by wrapping it again with new wool matched to the old color. This is called overcasting.
Left alone, a worn side loosens the threads behind it and starts to unravel into the border. Then the edge has to be rebuilt before it can be wrapped again.
The ends wear in a similar way. The fringe is the end of the warp, the lengthwise threads that run through the whole rug.[1] A narrow woven band at each end holds the last rows of knots in place. When that band wears away, knots start to come out one row at a time. A restorer secures the end by stitching across the base of the fringe, or rebuilds the band where it has gone. If the fringe is already lost, the knots are secured at the row where the rug now ends. Our post on rug fringe has more on this.
These are the most common repairs and the most urgent, because the damage keeps growing. As our rug care page puts it, a loose edge or a fraying end is inexpensive to secure and expensive to ignore.
Repairing holes, tears and moth damage
Reweaving is the repair for a hole. The restorer first rebuilds the missing foundation with new threads. Then they tie new knots in matched wool, row by row, following the design around the hole. It is the original weaving done again by hand, so it is slow. Good reweaving is hard to spot from the front.
Patching means sewing in a piece cut from another rug. It is quicker and cheaper, but it rarely matches. We would not choose it for a rug you care about.
Tears and splits usually follow a weak line, such as an old fold or the spot where a heavy table leg stood for years.[2] They are stitched closed from the back, and any lost knots are rewoven.
Moth damage depends on how deep it goes. If the larvae grazed the pile but left the foundation sound, the restorer knots new wool into the area. If they ate right through, it becomes a reweave. Either way, the rug should be washed first, so nothing is still feeding under the new work. Moths in wool rugs covers the rest of that job.
When a rug is restored for us, the specialists we work with reweave small areas of moth damage with matching wool. We generally do not buy rugs with large areas of it, because a heavily rewoven rug is no longer the rug it was. The whole process is in how our vintage rugs are washed and restored.
Color run, brittle foundations and curling
Color run is dye bleeding into a neighboring color.[2] Most often it is a red running into white or ivory after a flood or a pet accident. It can also come from a wash that was too hot or dried too slowly. A specialist who treats it quickly can sometimes reduce it or take it out. Once it has set, it may be permanent.[2] Do not try heat or bleach at home.
A brittle foundation is the hardest problem. Cotton that stays damp for a long time weakens from the inside.[3] This happens under a plant pot, after a leak, or when a rug is rolled up wet and stored. The rug then starts to crack or tear when it is bent. A restorer can support a weak area by stitching it or backing it. But when this damage runs across much of the rug, it is often not worth rebuilding. If a rug crunches when you fold a corner, stop folding it.
Curling and rippling usually need less than people fear. Most curled corners and fold lines settle with time, weight and a pad, as how to flatten a rug explains. A side that ripples along its whole length is different. It usually means the side wrapping is tighter or looser than the rest of the rug. The fix is to rewrap it, sometimes with blocking, which means stretching the rug flat and letting it dry that way.
Worn pile can be re-knotted. But even, low wear across a whole rug comes with age, and it is rarely worth the cost of repair. Be wary of anyone who offers to paint or dye worn areas to hide them. It is common in the trade, and it misrepresents the rug, so avoid it.
What about rug backing repair?
A hand-knotted rug has no separate backing. Its back is the foundation itself, the warps and wefts the knots are tied on, so backing repair on a knotted rug means foundation repair, as above. A tufted rug is built differently, with a cloth backing held on by glue, and once that glue fails there is little left to repair. Why hand-knotted rugs outlast machine-made ones explains the difference.
What is worth repairing
Start with anything that spreads. That means an unraveling side or end, a hole that catches a foot or a vacuum, a split, or live moths. These get worse, and more expensive to fix, every month. Cosmetic issues can usually wait, or stay as they are. Soft color, even wear and an old repair that is holding all belong in that group.
What does a Persian rug repair cost?
Nobody can answer that honestly without seeing the rug, because the price is almost all labor. These are the things that drive it:
- The size of the damaged area.
- The knot density. A finely knotted rug has many more knots to tie in the same space.[1]
- How many colors have to be matched.
- How much of the design has to be rebuilt.
- Whether the foundation needs work first.
Sometimes an estimate comes to more than you would pay for a similar rug in good condition. Then the question is what this particular rug means to you. If it matters to you for its own sake, that is a perfectly good reason to go ahead. The cost of rugs explained covers what makes one rug worth more than another in the first place.
How to choose a restorer
- Look for someone who works on hand-knotted rugs, not a general carpet cleaner. Many cleaners send repairs out, so ask who actually does the work.
- Ask to see before and after photos of similar repairs on similar rugs. Good reweaving is hard to spot, which is the point.
- Ask how they match color. The answer should be wool, chosen or dyed to match. Paint and markers are the wrong answer.
- Get a written estimate after they have seen the rug, or at least clear photos of the front and back. It should say what they will do and what they will leave alone.
- Trust the restorer who tells you when not to repair. Someone who suggests leaving stable wear alone is putting your rug first.
Can you repair a rug yourself?
Not much beyond first aid. Textile repairs are made with needle and thread, and even conservators choose the technique case by case.[4] What you can do at home is keep the damage from spreading until a restorer sees the rug. Keep the vacuum and foot traffic off a loose edge, a fraying end or a hole until then.
Avoid the home fixes that make a restorer’s job harder later. Glue, iron-on patches, carpet tape and markers on worn spots all cause trouble. So does trimming loose knots or threads, which lets more of the rug come undone. Adhesive repairs in particular are hard to undo, even for a conservator.[4]
If a rug you bought from us needs repair
Every rug we sell is washed, inspected and restored by specialists we trust before it is listed. If you want to know more about a rug’s condition before you buy, ask us and we will send more photos. Our authenticity page sets out what we disclose on a listing, from holes to significant reweaving and color run. If a side, an end or a patch of pile starts to go on a rug you bought from us, send us a photograph.
To keep a rug from needing repair in the first place, protecting a rug from sun, pets and spills covers the everyday habits. Do wool rugs shed? helps you tell normal fluff from real wear. And the one rule to remember is simple. Fix sides and ends as soon as they loosen, and leave even wear alone.
