Leave Job Sites Better Than We Found Them

When we remove plants or cut down trees, we replace them at the end of the job. Our team will stay days after planting trees and grass to negate any negative environmental impacts of our project. This includes planting up to 2 trees for every 1 cut down, building little lakes and water sources with quality irrigation to ensure plant and grass growth when the project ends, and upkeep on parts of the property only indirectly affected by the project.

Our commitment to environmental sustainability was recognized in early 2022 when the Institute for Sustainable Infrastructure awarded us with the Envision Verified Award for the Clearwell 9 Replacement Project!

With office locations in Westfield, IN, Merrillville, IN and Louisville, KY, we can serve quality construction services to the majority of the midwest.
