We are committed to making the claims process easy for you. We will meet with your insurance adjuster and make sure that you get the coverage you deserve.

Commercial safety guaranteed

We are OSHA certified and committed to safety on all our commercial jobs. All of our crews are required to follow OSHA guidelines no matter what type of work is being performed. You can be assured Zykan is always properly insured for any project so our customers can rest easy. Protecting our customers' property is very important to us, that’s why we take the extra steps necessary like tarping all areas that need protecting, covering garage doors with plywood, using safety cones, caution tape, road-hazard safety signs and tarping driveways anywhere a dumpster or vehicle may be parked.


Our goal is to provide our customers with a safe workplace, quality craftsmanship, completed on time while protecting property and leaving the site as if we were never there.
