Foundation Excavation

John Larson is awesome. We met through our mutual commercial construction contacts. He took on a tough sewer line install and executed flawlessly. Highly recommend. Honest and fair.

I had an absolutely wonderful experience with this company! From start to finish, everything was handled with professionalism and care. A special shout-out to John, who truly went above and beyond. He was incredibly kind, patient, and knowledgeable — you can tell he genuinely cares about the people he helps. John made safety a top priority while still working efficiently and making sure everything ran smoothly. It’s rare to find someone who balances both so well and does it with such a positive attitude. His dedication and friendly personality made the entire experience stress-free and enjoyable. If you’re looking for a company that values safety, efficiency, and outstanding customer service, I highly recommend them — and if you’re lucky enough to work with John, you’ll be in great hands!

Highly recommend John, great communication, fair pricing and excellent 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.

This company is absolutely amazing, any dirt work, grading, underground work needed this company Is the first call. John the owner is very responsive and knowledgeable. All around outstanding company

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.

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!
