A little about us

Through our well thought-out company policy, full of passion and commitment, we consistently strive for the effective mutual development of both ourselves and our customers, since together we are one. We strongly believe that such a philosophy is a guarantee of our mutual future success.

The MONOLIT Michał Godlewski company was established in September 2007, in Zambrów (Podlasie province). The beginnings were particularly difficult due to the strong expansion of competitors. Initially, the company's activity was limited to sales, although in 2014 we started our own production of windows and external PVC doors. This involved a number of investments in Zambrów, such as the construction of production facilities and modern machinery, including equipment well-known and highly esteemed by manufacturers in the industry (for instance FIMTEC-POLSKA, URBAN, HOLLINGER), together with administrative and warehouse space. Subsequent years saw the modernization and expansion of the business, which in turn allowed us to expand the range of products offered by the company with roof windows, external steel doors, window sills, mosquito screens and garage doors. Thanks to our knowledge and experience, we are able to offer products that meet the expectations of even the most demanding customers, both in terms of quality and functional specifications. The company employs professional staff and has a modern vehicle fleet.

The highest priority for us is to provide high quality products and optimally meet the needs of customers, who attach more and more importance to the quality and functional specifications of what they purchase.

It is worth noting that the development of MONOLIT not only involved technological, but also product development. Inspired by the ideas that the company's customers constantly come up with, we introduce new types of windows and doors to suit market demand.
