"He did an excellent job replacing our septic tank. He solved a difficult problem with a huge boulder that was blocking the move of the tank. Also was very careful not to damage the rest of the yard during installation. Overall, job well done. Quality job at a fair price."

"The service technician was 2 hours late and his price was $1900, I decided to get a second quote and I am so glad I did. I got the same job done with better tank and filter for $1100. My advice is get a second quote if you have time, I saved $800 by using another company."

"DBG Construction did a very good job with the installation of the septic tank and my yard. They also went above and beyond their jobs and repaired damages that was done by Paramount Construction 2 years ago. Paramount Construction was hired by MDC to put in new shut off valves in our neighborhood and which they did a terrible job, and yes I complained to MDC and nothing was done. Thank you DBG Construction for cleaning up their mess."
