Replacing the window furnishings in Minsk: why did the drive break after 17 years of service?
Someone came to me with a problem: the drive of the main lock on a window had stopped working. The hardware had served faithfully for more than 17 years. It's an old, solid model made of metal without a powder fill — such mechanisms were highly durable from the start. Modern analogues most likely wouldn't have lasted so long in similar conditions. As it turned out, though, the cause of the breakdown wasn't age but a simple lack of care. The mechanism could have worked just as long again if it had been looked after even occasionally.
What caused the breakdown
The main — and only — cause was the absence of regular lubrication. In 17 years the moving parts (the drive, the scissor mechanism, the corner switches) never once received preventive care. Working dry, the friction of the metal grew, the load on the drive increased, and in the end the mechanism simply couldn't take it and broke. An important takeaway: even the most reliable, "eternal" mechanisms need care.
How to make your hardware last for decades
So that your hardware serves for decades, follow a simple rule: once a year (ideally in October–November, before the cold) carry out preventive maintenance. This includes:
- Cleaning the mechanisms of dust and dirt.
- Lubricating all the rubbing parts (hinges, cams, gearbox, scissor mechanism) with a special lubricant (silicone or hardware lubricant).
- Checking and, if necessary, adjusting the pressure.
This simple procedure takes a specialist no more than an hour, but it extends the life of your windows for years and saves you from sudden, expensive breakdowns.
Frequently asked questions
Why did the hardware break if it's old and good quality? The quality of the metal doesn't cancel the laws of physics. Friction without lubrication leads to overheating and wear even of the strongest alloys. The mechanism simply jammed from the overload.
Could a replacement have been avoided? In this case the drive broke completely — it couldn't be repaired. A replacement of the unit was required. Had the care been carried out in time, the breakdown wouldn't have happened.
How much does a drive replacement and prevention cost? The price depends on the type of hardware and the condition of the window. I name the exact cost after a free inspection.

Don't wait for the hardware to fail. Annual prevention is far cheaper than replacing a unit. Call — I'll clean and lubricate the mechanisms and, if needed, replace worn parts.
