Warranty and post-warranty maintenance

As a standard, each product is covered with a five-year product warranty.

If our products are purchased, but without our installation services, we are committed to take responsibility only for the quality of our windows or doors, but if you also need the installation services, we will perform the warranty and post-warranty maintenance. This means that within five years, where there is the slightest problem, we will fix everything for free.

As UAB Vinkelis and KO has been in business for fifteen years, our clients feel safe buying our products, since the company's expertise and many years of experience is a guarantee for our reliability. After the end of the warranty period, we always help our clients to solve problems. Because no matter what happens, we will always be close to you!
