Customer Testimonials

I contacted [Penhall] for 2 floor scans on [a] 5th floor room. [They were] able to come and complete the work needed by [the] afternoon.
We thank Penhall for always being accommodating for our project success. [Jeff Tom, Superintendent from Layton Construction Company, LLC] 
The scan done of our existing slab saved both the owner and myself money and headaches. The scanned lines were undocumented power lines for future expansion. If we would have hit those lines it would have been a mess and would have not only cost our project money, but also the project in the future that is planned for those lines. Thank you for what your team did. [Tim Snideman, Snideman Construction] 
Penhall Company far exceeded expectations by completing the work well ahead of schedule and in a professional manner. [Britt Hurlock, Miller & Long, MD]
