Frequently Asked Questions
Everything you need to know about our window and door repair services
- When the gaskets lose their elasticity, begin to crack, or the windows become draughty and no longer seal properly.
- People often use the term "window rubber", but the correct professional term is window gasket or window seal. Modern uPVC window gaskets are typically made not from plain rubber but from specialist sealing compounds that offer greater resistance to temperature fluctuations, moisture, and wear.
- Not always. If the gaskets are significantly worn, adjustment alone is usually insufficient.
- They help reduce heat loss, improve the window's airtightness, and eliminate draughts.
- Yes. Faulty gaskets can lead to moisture build-up and significantly increase the risk of mould growth.
- Yes, the initial inspection and our technician's visit to assess the work are completely free. No hidden fees and no obligations. If you decide to go ahead, the technician will prepare a clear quote on the spot, explain everything to you and, if you agree, can usually do the work right away during the same visit.
- Of course. We provide a warranty both for the work carried out and for the materials used, in line with the laws of the Republic of Lithuania.
- The price depends on the type of window, the issue, and the materials needed. When the technician arrives, they give you an exact quote on site with no hidden charges, and you decide yourself whether you want to proceed with the repair.
- Yes, our window service operates all over Lithuania: in Vilnius, Kaunas, Klaipėda, Panevėžys, Šiauliai and other cities and towns.
- Booking a free visit is very simple. Just give us a call or fill in the online booking form – in both cases it only takes a few minutes.
- In most cases repair is enough: replacing seals or mechanisms, improving insulation, adjusting the fittings, cleaning and lubricating the hardware. This is usually much cheaper than installing brand new windows.
- Repair is cheaper, because you don't have to buy new windows, remove the old ones, dispose of them or redo the interior finishes afterwards. Repair saves both time and money and is significantly more cost‑effective.
- We work with all major brands: Rehau, Veka, KBE, Schüco, Salamander, Aluplast and many others. Our technicians are trained to work with the specific mechanisms used by each manufacturer.
- Yes, you can pay by all major bank cards, by bank transfer or in cash. Payment is made after the work is completed.
- Yes, we provide services all year round. In winter we use specific methods so that the room doesn't get cold during the work and your comfort is kept to a maximum.
