Here is what people are saying about Wilhelm Site Services LLC.

Awesome job clearing our building lot by Daniel and Peter! We were impressed with their professionalism and responsiveness throughout the entire process, from quoting to the finished work. Daniel, who did the actual clearing, worked hard, fast, and safely. He and his brother Peter obviously have strong work ethics and are serious about satisfying their customers. We can highly recommended Wilhelm Site Services!

They have done a lot of work for me from clearing trees, to putting in a site pad and driveway. They have always been very responsive and reliable cant recommend them enough

Professional, hard working and efficient. Pricing for job very reasonable. Follow-up was excellent! I would hire them again without hesitation.

I had my shed torn down by Wilhelm Site Services LLC. Peter & equipment showed up on time, had a dumpster delivered to my driveway. He and another man had all the equipment necessary. They tore it down, leveled it off with topsoil & planted grass seed.
Peter even called to see if everything was satisfactory. I would highly recommend Wilhelm Site Services LLC for your needs.

Jack Whitmer, Selbyville

Great experience! His team demolished and removed our old home to prepare the land for selling. Quick professional service. Thank you

Allen Krzemien


They were hired to demo a shed that was falling apart and to dismantle an enclosure around a car port that was warping. They did a great job, cleaned up after themselves and did a little more by ripping out 4 overgrown shrubs at my request for a great price.

Finally two young men with entrepreneurial skills. Contracted with them to level my lot in Milton - showed up on time and charged a fair price. It's easier to climb Kilimanjaro than it is to find competent and professional workers in Sussex County. As a retired contractor and developer - that's saying something. Will use again for excavating the foundation, God Bless and Godspeed.

Great place to do business with. I had an emergency situation and Peter made it happen for me. Plus the crew he sent over were courteous and hard working. Thanks Peter and Wilhelm Site Services!

RP Cook


Everything he said he was going to do, he did. Showed up the day he said he would. Communication was excellent, Contract was specific.

We hired Wilhelm Services to clear part of our property and remove some trees. Peter & his brother were very professional and respectful. They showed up as scheduled and finished the work in 2 days, despite the weather. We have hired them to level out some areas, add top soil & seed in March. Highly recommend - hire them, you won’t be sorry!!

Peter was extremely efficient and professional, He answered my phone calls and emails in a timely manner. Most importantly, the job he and his crew did was exceptional. They were also very flexible when I had to tweak a few things in the middle of the job. I am planning on hiring them in the not too distant future for another project.
