    Had Gavin do a new septic system in the past and had him back for some driveway work today. As before, his work is top notch. He is always punctual and very careful with his equipment. Will use him for any future work as needed.

    Gavin put in my septic. He made the entire process very easy and straightforward. His engineer is also extremely nice and walked the area where the septic was going in discussing what i needed and the different types of septic available. Gavin is very professional and kind. He was very careful with his equipment and didnt tear up my yard more than needed to get the septic tank and lines in. He was very efficient. It's been almost 4 years now and i haven't had a single issue with my septic. I would absolutely recommend blackwater excavation!

    January 2025

    I hired BlackWater Excavation to install a septic system for my new construction home and a second system for my shop & RV. Both projects were completed in a timely and professional manner. Gavin and his team kept me informed of progress and made sure all my questions were answered throughout the job. I was so impressed with BlackWater I had them come back and perform some driveway work and trenching for water lines. I cannot recommend them enough! Gavin will be my first call for any future work.
