C and G Earthworks has gone above and beyond with every project for me. The communication was clear and they were efficient to the their time. We had them build a road to our new home, prep the area for the new build , and excavated the area for our new septic tank. Cade and his crew were friendly and informed us of his progress daily. We have several other projects they will be helping us with as our property develops, and we are lucky to have found C and G earthworks. Thank you team for the hard work and communication.

Had my driveway fortified and expanded. Lazy K did an exceptional job – opposite of lazy. Called for a bid and LK was on site next day ready to go. Went weeks with another local contractor to get bids only to get blown off continuously… LK bid the job on a Friday, work was done Monday. Came in under bid and the completed work was exceptional; could not be happier!! Great folks to work with. LK’s legacy of excavation/dirt work experience would be very hard to match, and it shows… these guys get the job done right. Would highly recommend!

This was a new experience for my wife and I, taking a bare lot with utilities at the property line and starting the process of building a home. Lazy K Excavation held our hand in the process of getting an address based on where we wanted a driveway, water and electric hookups, etc. It was also a new experience for us dealing with a contractor that responded the same day to calls and texts, had an itemized estimate the next day, and literally an on the fly estimate after we met and decided we needed a longer driveway than initially planned. We weren’t in a hurry, yet they got our job completed in a day and a half, arranged to have the water hooked up during this process, and we couldn’t be happier! We’re still figuring out where to put the house and “man shed”, but rest assured, Lazy K will get our future business. I wish every other contractor I had ever dealt with had their professionalism. The contractors they recommend for other services are also top notch. Talk to them first, your life will be easier!
