Our Satisfied Clients Can Speak For Us

Over the past 10 years, we at REG Seneca have used Conley Excavating for numerous jobs. These jobs may consist of some type of earthwork to any type of concrete work. The Conley family has built a company that in my opinion is fantastic. My view is that their company is built from three things: Safety, Quality, and Integrity. With these values, it shows in every job that Conley has done over the years. We have relied on Conley for not only earthwork but for concrete work as well. I can say that every job that they have done, has been done with the three values in place: Safety first, Quality workmanship, and the Integrity of a job that was completed in the right way each and every time. I would highly recommend Conley Excavating for any and all construction work that you may need and I can assure you that you will not be disappointed.

Homer Township would like to take this opportunity to commend the entire Conley Excavating and Construction team on their continual commitment to professionalism and excellent customer service. Our experiences over several years working with Conley team members on various phases of the Lockport Heights Sanitary District water main replacement project and in the restoration of the Morris Park irrigation system pumping station have demonstrated a high level of expertise, adaptability, and determination to find viable solutions to challenging circumstances.

Further, the additional paperwork and obligations required complying with governmental grants and regulations of public works projects can be immense and time-consuming. However, your team has always enthusiastically accepted the conditions, efficiently managed the compliance workload, and promptly met all deadlines.
We wish your organization continued success and look forward to future projects together.

We know that from the time you arrive on site until the time the job is finished, there will always be that high level of professionalism from everyone on your staff whether in the office or in the field.

The attention to detail includes going above and beyond when dealing with our taxpayers/residents to make sure that the projects limited inconveniencing every single person as little as possible from the initial first dig to the final restoration details. We also appreciate your sharing your professional experience on all our projects that helped the District make better-informed decisions that expedited work and saved taxpayer dollars.
