    Dan made time to show up as soon as possible. He showed up on time and quickly told me there was a very simple solution for what looked very concerning to me. He didn’t try to upsell, gave me some information about what I was looking at and why it’s ok, and then offered to coordinate my solution to keep it simple for me. As a homeowner, parent of three, and business owner, life can be complicated enough without all these unexpected home repair issues. I really appreciate the experience.

    As an owner of a home with a fair share of issues, I have NEVER had the pleasure of a job (in this case a septic tank replacement +) done with such efficiency, thoroughness, and excellence ( I do believe Daniel could tie a knot with that excavator!). They delivered with the utmost patience and care, and completed the work with impeccable follow through! John, David, and Daniel are a rare find in my mind and I HIGHLY! recommend their workmanship and professionalism. The cost of the work was slightly higher than other estimates but in the final analysis, I actually think I got the better part of the deal! I 100% trust them for future work on my home!

    Careful, thoughtful, and unrelenting in difficult, sensitive situations where rock needed to be extracted without damaging nearby structures. Intelligent and friendly personnel, too! I highly recommend these folks!

    I had a very particular 1 day job that needed expert care and efficiency to complete. Including pushing a 250 year old stone wall back into place. Daniel gave me a quote, showed up when he said he would and completed the job exactly as I needed. I highly recommend Daniel, he is an expert with an excavator.

    Just had Nilsen in to do some excavating for a tricky driveway (needed to remove bedrock to get good grading w/o disrupting existing utility lines). Super impressed - very knowledgable, responsive, communicative, fair pricing. Can't say enough. We're incredibly happy with their work. Would recommend them in a heartbeat!
