About Us

Sealant Engineering Construction Supply, the leading Chicago area distributor for silicone, urethane and latex sealants and waterproofing products for over 20 years, has joined with Coastal Construction Products, one of the largest independent distributors of caulking and sealants, waterproofing, concrete repair, and fire protection products in the US. Like us, they have a long history of providing solutions, not just products.

Sealant Engineering and Coastal share the values and expertise that can only come from years of experience in the field.  You can feel confident that we will continue to provide the best product knowledge, solutions and service for your remedial and new construction projects.

As we continue to grow and add resources, here are a few things you can look forward to:

  • Access to new lines of best-in-class construction materials
  • Increased communications on industry news
  • A new, larger facility with more warehouse space

From towering curtain wall structures of the central city to the sprawling corporate campuses of the suburbs, Sealant Engineering has worked closely with building owners, architects, construction managers, general and subcontractors to provide lasting, leak-free solutions for large structures. We look forward to continuing to provide you with the products and services you need for many years to come.
