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.

Very professional. I would highly recommend this contractor. Jacob handled everything promptly and efficiently, making appropriate suggestions and completing the job on time and budget. He was always available or in contact. Very pleased I hired Wilhelm for my lot prep.

Jacob and his team were hired to clear a heavily wooded area for me totaling approx. a half acre in size. I had hired other companies prior to finding Wilhelm Site Services, but they never showed up. Jacob was on time every day and didn't leave until his goal for the day was met. His price was fair and he went above and beyond. I appreciated that he respected our property and didn't leave trash or debris on the job site. I will be hiring Wilhelm Site Services again.

Jacob is a real pro. He and his team did a great job installing a pad for a paver patio at our home. Quality work and attention to detail. Great customer service. Friendly. Timely. And cleaned up thoroughly before they left. Would hire him again for sure.
