Frequently asked questions and answers
We answer the most frequently asked questions directly and clearly. We will help you navigate the entire process — from window selection to calculation to installation. We want to make changing windows simple, carefree and fully in control for you
I don't want to spend weeks picking and getting nervous about it. How's it all going for you?
We understand that window selection is not your daily concern. That is why we have created a process that is understandable and guides you step by step. Immediately after sending the request, our specialist will contact you, who will help you with the choice, focus your house and recommend the most suitable solution. We will clarify everything in advance — including the price, schedule and type of assembly. Our team will make sure that the process runs smoothly without unnecessary complications. When you're done, we'll get back to you again, check your satisfaction and offer a free adjustment.
How do I know if the installation is done correctly and that the windows are sealed?
Proper installation is key to the tightness and longevity of windows. We will show you how to easily recognize the quality of the work done — from the correct installation of the frame and functional fittings to checking the tightness and checking the connection joints.
I am interested in ecology and savings — what do you offer besides classic plastic windows?
SULKO develops innovative materials that combine aesthetics, performance and environmental friendliness. For example, our ARTEVO composite looks like aluminum, but it is close in price to plastic products and contains recycled components. The windows have exceptional thermal insulation, which allows you to reduce heating costs by up to 76%. If you are looking for a modern and sustainable option, you have come to the right place.
What if something goes wrong? Do you offer any service at all?
Service is not the last chapter, but part of the whole story. Each customer has the opportunity to use the free adjustment within 6 months of installation. If something doesn't work, we respond quickly -- by phone or personal visit. We also offer a 20-year warranty, so you don't have to worry about your windows in a few years. We build trust on care, not just contracts.
