Venetian blinds increase the classy feel of your windows and enable you to regulate how much light illuminates your house or room by tilting them down or up. When you raise Venetian blinds, the bottom slate rises into the slat above it. Over time, a blind slat becomes a damaged slat. I should emphasize that Venetian blinds are the market’s most popular choice of blinds for new window treatments.

Even if these high-quality products are of high-quality manufacture, expect wear and tear to take its toll. Whether you want to buy replacement parts, individual slats will wear down with constant use. It’s a good idea to have new replacement slats handy when the time comes. If you cannot open your blinds, check the tilt cord lock mechanism for jamming or if repair is required. There are many common problems and while I have not had issues with my old lift cord, Amazon has a wide range of options to get a new lift cord, as needed. Replacement cords are not that expensive.

If you cannot adjust your blind angle, the cord tilter mechanism may have a snag or damage. Window blinds are a complex design and there are many common programs such as a broken slat, broken string, damaged ladder strings, pull cord or blind cord is a common experience. Get used to replacing lift strings and the bottom slat for a new slat on your horizontal blinds.

There are many styles of window coverings that can be vertical blinds or horizontal blinds. Beyond Venetian blinds, you can choose mini blinds, micro blinds, panel blinds, and smart blinds. For material, you have a choice of wood blinds, faux wood blinds, metal blinds, fabric blinds, and specialist textiles. Some offer a classic look, while others can breathe new life into your room or kitchen. Venetian blinds are also called aluminum blinds.

I will write about the types of blinds to consider in a future article. The important part to remember is that window shades also help with light control, but each set of blinds offers a different aesthetic. The style of blinds is also a personal decision. We will look at cellular, layered, natural, pleated, roller, roman, sheer, solar shades, sliding panels, and shutters as options for new blinds.

You can fix Venetian blinds in three different ways.

Free the Stuck Blinds

Try to lift the bottom of your blinds to reduce the weight caused by the locking mechanisms. Using your non-dominant hand, grab the bottom of the bottom rail, mainly in the center, and hold the weight. Lift your blinds to the top of the headrail, which the section at the top of the blind attached to the wall. Pull the lift cables with your dominant hand while you raise the blinds to examine whether there is any slack or if the control pulley has control of the blinds. When cords cannot pull and adjust the vertical height of the blinds, you must force the lock mechanism to open.

Take the headrail out of your mounting brackets. Take the bottom of the valance (a decorative part covering the headrail). and pull it towards you slowly to remove it. Try opening the mountain brackets at the side of your blinds and pulling the headrail out. Slowly guide your blinds away from your window, then lay them on a flat surface. 

Certain headrails or valance clips require a screwdriver (a flathead screwdriver is vital). Be extra careful to avoid damaging your blinds as they could bump into objects as you take them down. Press down on the serrated rollers using a screwdriver to open the blinds. Take a glance at the headrail close to where lifting cords as the cord lock has two plastic and metal rollers. To release the ridged roller, place the end of a flathead screwdriver on top of it and press down. Your lift wires will come free once the roller gets freed, allowing you to regulate your blinds.

When the roller breaks, your broken blinds require you to replace the cord lock. Pull each chord simultaneously to keep your blinds from becoming misaligned when they’re open.

If your blinds are still not working, try replacing the cord lock.

  • Start by removing any tassels that might come in the way by untying the knots just at the end of the lift cords.
  • Disconnect the cable lock by removing the end stiffener (the component at the end of a headrail) using pliers
  • Break the cord lockout of other tabs with a screwdriver, then slide everything out the other end with a screwdriver
  • Insert the cords between the headrail and rollers by pushing a new cord lock into position
  • To complete, connect the cord tassels

Things to Keep in Mind

  • You can purchase cord lock mechanisms for your blind online or in specialty stores for a simple repair
  • Double-check that the new cord locking mechanism you buy will fit in the blinds’ headrail.
  • Blinds that won’t remain open require a fix by changing the cord lock.

Check the tilt mechanism

The first step is to remove the blinds away from the window’s mounting bracket. When engaged, remove the valance that covers the headrail, then lay it aside. Also, using the end of a flathead screwdriver, break open some mounting brackets, mainly on the side of your head rail. Gently remove the blinds and place them on a flat surface to avoid damage or tangles. Several headrails and valances may require screws to be screwed through into your wall or into mounting brackets.

Check for snagging inside the tilt mechanism when cords operate these blinds. Its tilt mechanism, a gear or spool, would be like the wand or wires that regulate the slats’ angle. If you are using cords to adjust the tilt of your blinds, take a closer look to see whether a loop of excess cord has fallen from the spool & formed a snag. If this is the case, draw the loop back to your spool to allow the cords to pull correctly.

Disconnect the twisting wand and string tassels from your tilt mechanism. Remove the knots at the ends of the cord so the tassels may slide off if you’re using cords to adjust the tilt. When you have a twisted wand, raise it, then detach it off the mechanism because it can’t even fit past any headrail once you separate it.

Remove the ending stiffener off any blinds’ headrail. This end stiffener seems to be the portion at the headrail’s end that prevents the parts and mechanisms from sliding out. With such a pair of pliers, carefully peel the ending stiffener out of the headrail.

Remove the tilt rod first from your tilt mechanism by sliding it out. This tilt rod is the metal bar that turns your blinds & runs throughout the length of the headrail. Pull your tilt rod out from the tilt mechanism gently until it’s entirely free. If you can’t move the rods far, you may have to disconnect the ending stiffener from the other end of the headrail.

Then, you pull the mechanisms out of the headrail and insert a new tilt mechanism on your headrail. Last, secure the wand or tassels back onto the mechanism.

Replacing Damaged Slats

Using a flathead screwdriver, detach the caps from the bottom of your blind. Before you start, ensure the blinds remain fully stretched & horizontal. Locate the two or three caps that hold the cables in position, mainly on the bottom railing of the blinds. Pry your end caps off the rail with the edge of a flathead screwdriver to reveal the knots underneath.

Remove the knots that have been securing the cords in position. Remove the ropes from the bottom rail to allow entry to the knots. Using your fingers, separate these knots so that the cords remain level and can easily pass through all the openings, mostly in blind slats.

To withdraw the slats, draw the lift wires through to the blinds. Pick up the end of the old cord, which runs via the center from one slat you wish to fix. Pull the rope up and out of the slat you like to detach and all the others beneath it. Before sliding the slat out of position, remove all the cords that go through it. For blind repairs, install any remaining slats using the same procedure.

Repair damaged slats inside the slots previously detached so that your blinds wouldn’t clash once you finish. Acquire slats similar to your present ones. Locate the place from where you removed the old slat and slip the replacement one into it. Ensure the lift wires align with the openings in the center. Repair some other slats with the same procedure.

Before you reach the bottom, feed your cords via the openings in the slats. Before restoring the caps, create knots throughout the draw cords.
