About Slawek Improvements

From windows and doors to gutter installation and repair to expert fascia and soffit installations, Slawek Improvements has served discerning homeowners in the Chicago area for more than 15 years.

In the world of big box stores and corporate-owned chains, Slawek Improvements has always been family owned and family operated:

  • In the beginning, Slawek Improvements had one employee. Window installation was the company’s primary service offering.
  • As the customers spread the word about Slawek Improvement’s quality work and state-of-the-art products, the business grew steadily and more services were added:
    • siding installation
    • gutter installation and repair
    • wood window and entry door installation
    • interior door installation
  • Today, Slawek has a team of three full-time crew members that includes Daniel Bigos, Slawek’s brother. Mr. Bigos is the company’s foreman / job supervisor and has been with the company more than 10 years.  Slawek is now involved in the day-to-day operation of the business including management, business development, and sales.  The entire crew has over 50 years of combined experience in construction industry.

Our highly-skilled team allows us the flexibility to take on smaller jobs such as the installation of one kitchen window and the larger jobs such as installing 100 or more windows in an apartment building.

Throughout the years, Slawek Improvement has steadfastly maintained the same mission: to sell reputable products at a fair price and provide superior service.  No job is too small.
