Why Do Plastic Windows Fog Up? When It’s Normal and When to Worry
Waking up to water droplets on the window? It doesn’t always mean the window is broken. We explain when condensation is normal — and when it’s a warning sign.
Find out how cheap and quality window and door hardware differ, which parts fail most often, and when it pays to replace versus repair.

Most people only start thinking about window and door hardware when a window begins to jam, closes with difficulty, or a draught appears. But professional window technicians see the differences between quality and cheap components much earlier.
In practice, situations frequently arise where two visually almost identical windows look entirely different after 10–15 years. One still operates smoothly while the other already needs repair or even replacement of several mechanisms. The difference most often comes down not to the window profile itself but to what hardware was installed and how it was maintained.
In this article we discuss how cheap and quality components differ, what we most commonly see on site, and when it is genuinely worth investing in better mechanisms.
When a technician arrives at a job they assess not the brand name but the overall condition of the mechanism. Even quality hardware can be heavily worn if it has gone without maintenance for many years.
What is checked: the degree of mechanism wear, signs of corrosion, the condition of hinges and compression points, adjustment options, handles, and the operation of the transmission mechanisms.
In practice clients often think the problem is in the window itself, when in reality only one hardware component is worn. In such cases repair or replacement of a single part is often sufficient, without renewing the entire mechanism.
Most new-build projects use hardware that is perfectly adequate for everyday use. However, its grade can vary considerably depending on the project budget.
Economy-grade projects most often use basic solutions aimed at a lower price point. Mid-range projects use more reliable hardware with more adjustment options and better wear resistance. Higher-end projects more frequently feature advanced solutions that provide a longer service life and greater user comfort.
It is important to understand that even good hardware needs maintenance. A common problem arises not because of the manufacturer but because mechanisms have not been cleaned and lubricated for many years. Proper mechanism cleaning and lubrication once per season extends the service life of hardware in any grade two or three times.
In Lithuania the hardware most commonly encountered comes from several of the major European manufacturers. Winkhaus, Roto, and Maco systems appear most frequently.
Over many years in service all of these manufacturers have produced both highly reliable and more basic solutions. The brand name alone therefore does not always tell the whole story.
What matters far more to technicians: the specific mechanism series, its age, maintenance history, availability of spare parts, and the overall level of wear.
Many clients are surprised to learn that mechanisms that look similar at first glance can serve for entirely different lengths of time. The difference is usually determined by the quality of the metal used, protective coatings, manufacturing precision, and the design of the mechanism.
In practice it is common for 10–15-year-old quality hardware to work better than much newer cheaper mechanisms. This is precisely why professionals assess not the manufacturer or the window's age but the actual condition of the mechanism.
One of the most common mistakes is assuming that when a mechanism fails the entire hardware set needs replacing.
In practice it is often possible to repair or replace only individual parts: handles, compression elements, certain hinge components, and individual hardware assemblies. Full hardware replacement is more often required when mechanisms are heavily corroded, spare parts are no longer available, or too many worn components are present.
The parts most commonly repaired or replaced are handles, corner transmission mechanisms, compression elements, balcony door hardware assemblies, and hinge components.
Another frequent problem is worn seals. They harden, crack, and lose elasticity — seal replacement is typically needed every 7–12 years depending on frequency of use.
If you plan to live in the property for a long time, better-quality hardware often pays for itself through a longer service life, more consistent operation, and lower repair costs in the future.
However, if windows are used infrequently or the whole structure is to be replaced soon, it is not always necessary to choose the most expensive solutions. What matters most is not the price itself but whether the chosen hardware suits your actual needs and whether it will be properly maintained — regular adjustment and lubrication matter more than the manufacturer's name alone.
The difference between cheap and quality window and door components usually becomes apparent not on the first day after installation but after many years of use. Better-quality mechanisms generally maintain precise operation for longer, have more adjustment options, and require less frequent major repair work.
Even the best hardware is not eternal, however. Regular maintenance, periodic diagnostics, and timely window servicing often have a greater influence on service life than the manufacturer's name alone.
