Stability and Bonding that Minimize Risk

Winter Environmental delivers stability and security through the steadfast financial resources of The Winter Construction Company, an ENR Top 400 Contractor that has been in business since 1964. This means peace of mind for our clients as it assures we will be around long after a job is complete.

Our overall insurance program includes $25,000,000 in general liability coverage and $10,000,000 in pollution liability coverage. Our bonding capacity is in excess of $300,000,000. These metrics are as strong as can be found in the environmental industry, and serve as another reason you can trust putting your confidence in us.

Maintaining High Standards by Doing Our Own Work

Winter Environmental self‐performs virtually all work on site. The services we typically subcontract include scaffolding, hauling, disposal, drilling, laboratory analysis, certain proprietary technologies and certain specialty trades or technical expertise, if needed. This high level of self‐performance allows us to assure lower costs, a safer work site, higher quality control, faster completion times and better adaptability to unexpected circumstances.

Sophisticated Logistics Mean We’re Ready for Anything, Anywhere

Rather than incur and convey the costs of satellite offices, Winter Environmental serves its clients from a single operations center in Peachtree Corners, Georgia. Here, we can coordinate resources and focus on efficiently delivering project teams and equipment virtually anywhere.

Early on, we chose to invest our capital in achieving the most efficient logistical project support capabilities. Employing the latest in equipment tracking technologies (bar code, GPS, specialized inventory tracking software), and a full‐time logistics management staff, Winter Environmental applies a programmatic approach to the management of equipment and materials purchasing, inventory, dispatch, receiving, maintenance and use. We know precisely where every piece of owned equipment is today and where it will be needed tomorrow. We track expendable supplies on each job site daily. Field personnel statuses are tracked according to skill set, status of certifications and training, grade, current assignment and term and hours worked or in transit.

Environment is In Our Name and It’s Always Top of Mind

Cleaning up contaminated sites is inherently a sustainable practice. But Winter Environmental goes a step further. Where feasible, we look for opportunities to:

  • Reuse/recycle deconstruction and demolition materials
  • Consider future site use and reuse existing infrastructure where possible
  • Reduce generation of GHG emissions by using clean fuels and recycled industrial materials

Our project managers and staff are committed to helping our clients show regulatory agencies and the public that they care about energy and resource conservation. In addition, our environmental remediation professionals are dedicated to staying current on any and all news on regulations and practices that might affect a project or job site.

At Winter Environmental, completing projects and creating partnerships with the highest level of client service is our mission. This mission is only achieved when our clients are satisfied with all phases of their project – both at the moment of completion, and for as long as the site is operational.
