Jason did a great job on regrading our driveway to improve drainage away from our garage. Great communication and pricing, and got the exact finish product that we were looking for.
We needed to expand our driveway and fix a drainage issue. Jason met with us to discuss our options and completed the work quickly and exactly how we envisioned. I highly recommend J&M Earthworks!
Jason is extremely professional! He makes excavations as easy as eating ice cream! We are in Hill NH and couldn’t say enough about his work. He gave us a drawing of what he was going to do, as well as a list of exactly what we should expect, and how long he was going to need. We are so happy that he was able to quickly come to us, and did the work perfectly!
Jason did a tremendous job on leach field!!! THANK YOU!!! From May Brosseau and Steven Garland
Had Jason come to my home last year to discuss removing an old beat up rotten concrete slab and Replace it with a full foundation. By spring, my scope of work had changed and he recommended doing a retaining wall and gravel area as an alternative. It was just what I needed.He saved me thousands of dollars!! On top of that, Jason is very easy to work with the job he did was perfect. Could not have asked for a better experience. I cannot recommend or thank him enough
