Why Do Window Problems Appear in New Construction Apartments?
New-build residents are surprised when balcony doors start sticking after just a few years. Window problems in new apartments are not as rare as they seem.
Learn which signs indicate windows need repair, adjustment, or sealing, when to call a professional window technician, and how to choose the right service.

Most window problems develop gradually, so people do not notice them at first. The windows still close, but mechanisms begin to operate more stiffly, a draught appears, or airtightness decreases.
Noticing the first signs of a fault in time often helps avoid a more complex repair later. Professional window repair in most cases costs considerably less than replacing all the windows.
The first signs of a fault usually appear gradually. Initially windows become harder to close, a slight draught appears, or the window handle starts operating unevenly.
The most common signs:
the window catches on the frame,
the handle moves more stiffly,
a draught appears,
airtightness decreases,
mechanisms begin to squeak,
moisture accumulates.
In such cases it is recommended not to delay diagnostics.
Complex repair is not always necessary. Sometimes the problem can be resolved by professional window adjustment or hardware maintenance.
However, if mechanisms are heavily worn, components are damaged, or the window has been improperly operated for a long time, hardware repair or part replacement may be required.
Professional diagnostics allows the cause of the problem to be identified precisely and the most appropriate solution to be chosen.
If repair is not carried out for a long time, the load on mechanisms increases and hardware wear accelerates. Minor problems often become more complex faults over time.
For example, reduced airtightness can lead to greater heat losses, and unevenly operating hardware begins to wear other parts of the mechanism. This is a common reason we carry out window adjustment in Šiauliai.
Timely repair helps maintain smooth window operation and reduces the likelihood of larger costs in the future.
It is recommended to call a professional technician when the window does not close at all, the mechanism jams, or the problem recurs after adjustment.
Experienced technicians can quickly identify the cause of the problem and apply the most appropriate repair or adjustment solution for the specific window system.
A broken window is more than a minor inconvenience. It directly affects the comfort, security, and even the energy bills of your home. Finding a good specialist to solve the problem may seem daunting, but this practical guide will help you confidently choose a reliable window repair service.
Once you know what service you need, it is time to look for the right specialist. These steps will help you assess potential service providers effectively.
Begin with recommendations from friends, family, or neighbours — this is often the most reliable route. Then broaden your search online. Look for companies with good reviews on Google or other local directories. A professional website presenting completed work and clear contact details is also a sign of trustworthiness.
This step is essential for your own protection. Make sure the company or technician holds the required permits to work in Lithuania and is insured. A reliable contractor should be able to provide:
A business certificate or individual activity permit: This confirms that the work is carried out legally.
Public liability insurance: This will protect your property from damage if something goes wrong during the work.
Do not rush to accept the first offer you receive. Contact at least three different technicians and ask for a written quote after they have inspected the windows on site. A price given over the phone is often inaccurate.
Each quote should be detailed — materials and labour costs must be clearly itemised. When comparing offers, consider not only the final amount but also the proposed solutions, material quality, and timescale. Be wary of an unusually low price — it may mean inferior materials or poor workmanship.
Once you have chosen the most suitable specialist, check the following before finalising the agreement:
Guarantees: Find out what guarantees the technician provides. There should be a guarantee on both new parts (e.g. double-glazing units, hardware) and on the work carried out. This ensures that any problems that arise will be rectified free of charge.
Contract: Never start work based on a verbal agreement alone. Always sign a contract that clearly defines the scope of work, materials to be used, final price, payment schedule, and completion deadlines.
When dealing with technicians, trust your instincts and avoid those who:
pressure you into a quick decision and use aggressive sales tactics,
are reluctant to answer questions about licences, insurance, or guarantees,
are unwilling to sign a detailed written contract,
demand a large advance payment before work begins,
are difficult to reach and do not respond to calls or messages.
By following these systematic steps you can feel confident in choosing a technician who will repair your windows to a high standard.
