The story of SULKO
We have been engaged in the production and installation of windows and doors since 1993 and during that time we have gained thousands of customers in the Czech Republic and abroad. SULKO is a purely Czech family company that builds on traditional values and at the same time strives to be at the forefront of product quality and technological maturity. We offer a complete system of solution for opening fillings for demanding customers in family, apartment and prefabricated houses, we deliver our products to administrative and commercial buildings as well as schools, both at home and in Belgium and Switzerland.
I believe that through our long-term presence in the market, long-term growth of the company, expansion of production capacities and introduction of new products on the market, as well as our personal approach to customers, we have proven our reliability, credibility and top quality. I feel a great personal commitment in this and will strive to continue to contribute to these values myself as much as possible. Our mission is to enthusiastically provide products and services that will enhance the quality and utility of the customer's housing. We would like to become the most recommended Czech manufacturer of windows and doors.

Our Values and Commitments to Customers
These values form the basic principles according to which we manage every order at SULKO — from the first contact to the completion of the assembly. They are a commitment that we take as an integral part of our standard of service.
Diligence at every step
We manage every order systematically — from the focus to the final inspection. Every detail has its own “owner”, and we leave nothing to chance.
Expertise and smart solutions
We rely on experience, own development and modern technologies. We recommend solutions that make long-term technical and economic sense.
Confidence in communication and management of expectations
We share every step of the project transparently — with clear information, realistic deadlines and responsible management of expectations. The client always knows what stage his order is in and what will follow.
Reliability and long-term care
We are a partner for the entire window lifecycle — from selection to service. The order does not end with assembly, but only with your satisfaction.
