Why homeowners recommend Derner Enterprise

See what people notice most honest service, solid work, and results that hold up

I have been in the construction business for over 35 years. I had a friend who needed a gas line run from the LP tank to the pool heater. I looked at the job and it was very complicated, going around trees, flowerbeds, and elevated planters. It was too much for me to do, so I contacted Jake at Derner Enterprise and referred the job to him. When I went back to look at it, I was amazed at how he got the line buried and everything looked just as it had before the job was done. My friend couldn’t have been happier with the results.

Needed a level, graveled pad for a new storage shed I had already ordered. Derner Enterprise got it handled within the tight schedule, and at a good price. Even used the existing dirt on my acreage to build up the pad, and fill other low spots. Would definitely recommend them.

Had Jake trench 250ft to do a sewer tie in. He had to trench through my nice lawn. The care he put into make my lawn look good at the end of the job was amazing. Great service
