It depends on what is wrong with them. Generally, it will cost less to repair vertical blinds than it will to replace them. If the slats are just out of alignment, a technician can usually fix them for a relatively low cost. If the cords are broken or the mechanism is malfunctioning, it will likely cost more to repair them. In some cases, it may be more economical to simply replace the vertical blinds altogether.

It depends on the type of repair that is needed. Generally, repairing vertical blinds ranges from $10 to $50 per blind, depending on the type of repair required. Some common repairs include replacing the cord, fixing the tilt mechanism, and replacing the slats. If the brackets that hold the blinds together are broken, then a new set of brackets will need to be installed, which will increase the cost of repair.
