Commercial Caulk and Sealant Services to Help You Keep the Weather Outside

Got leaks? Our commercial building caulking and sealant services will repair or replace aging and faulty building seals.


Weather reports these days are filled with extremes, from temperatures to rainfall, snowfall, and winds. Over time, these extremes combined with UV radiation will degrade the building seals designed to keep the weather outside. While regular maintenance is the best way to extend the life of your seals, they may need replacement eventually with commercial sealant and caulking. 


RestoreWorks uses only the highest quality sealants available to provide the best possible seal and longest product life. As a trusted commercial sealant company, we also specialize in commercial caulking repair to address any issues promptly. Let our experienced caulking and sealant contractors bring life back into your buildings.

FAQs About Caulking and Sealant Contractors

  • What do commercial caulking and sealant contractors do?

    Commercial caulking and sealant contractors apply specialized sealants to prevent air, water, and moisture intrusion in commercial buildings. This includes sealing around windows, doors, joints, and concrete surfaces to maintain structural integrity and energy efficiency.

  • How often should commercial caulking be replaced?

    Most commercial caulking should be inspected every 5 to 10 years, depending on exposure to weather, UV rays, and building movement. If you notice cracks, gaps, or moisture intrusion, it's time to call a commercial caulking contractor for an evaluation.

  • What’s the difference between sealant and caulking?

    While the terms are often used interchangeably, caulking is typically rigid and used in areas with minimal movement, while commercial sealants are flexible and designed to handle joint expansion and contraction. Both are critical in commercial building envelope protection.


  • Do you serve both Chicago and Northwest Indiana?

    Yes, RestoreWorks provides commercial caulking and sealant services throughout Chicago and Northwest Indiana. Our team is familiar with the specific weather conditions and building materials common in both regions.
