I had a great experience with Spark grading service. John's pricing is very fair compared to others I looked into, and he really goes above and beyond in terms of service. You can tell his team is genuinely passionate about what they do. John attention to detail and care for the work is really stands out. John is also extremely knowledgeable and took the time to explain things clearly, which I really appreciated. What impressed me most was his honesty and willingness to suggest cost-saving options rather than just upselling unnecessary services. It’s rare to find a business that balances quality, expertise, and integrity so well. Highly recommend to anyone looking for reliable, affordable, and trustworthy grading services.

Gave me a great quote on installing septic for my adu, scheduled the work to be done in 2 days (paying a rate per day) and John banged it out in 1 day and charged me just for the 1 day. Great quality work, left the property looking better than when he came. Would recommend him to any friend or neighbor.

I contacted Sparks UG with a unique request of building a pit bike track in my backyard. John came over to survey the work area and come up with a game plan to tackle the track build and meet my requirements. The whole process from start to finish was smooth, great communication throughout and the jumps came out perfect. Lucky for me, John also rides dirt bikes and knew exactly how to shape and space out the layout to work for the small pitbikes. I would highly recommend Sparks UG for your dirt needs, very professional, knowledgeable, good attention to detail and John takes a lot of pride in his work.

Jonny and his crew at Spark made quick work of my finish grading project. They were prompt, worked quickly, and at a fair price. These guys are pros! Definitely give them a call.

Spark UG has been the epitome of professionalism, and continues to deliver our goals on time, and supply us with an end product that exceeds our standards. We could not recommend them more to anyone needing grading, excavation, or underground utility work. Thank you!!

We were looking for someone to do some grading for us at our property. After looking around we had contacted John at Spark Underground and Grading. We explained what we were looking to do and he was all over it suggesting ideas. We had him come out and take a look at what we needed and ended up choosing them to come out and grade a pad for us. Was an awesome experience, easy to talk to. It came out perfect and exactly what we needed. We will be in contact with Spark Underground and Grading to do our house pad and underground utilities. Highly recommend!!

John is a great asset to have, has all the right tools for every job. Very professional treats job and crew with a lot of respect, super clean work!
