I used Plog Engineering for a boundary survey for our home. I would highly recommend them!
Diana responded to my inquiry promptly. I had a proposal shortly thereafter. The team showed up when scheduled and did excellent work. Our property has a complicated history, and the records are somewhat confusing, but they took the time to do the job right.
It was easy to work with Plog, and I believe they were a good value for the services delivered.

This is one of the best companies for people to lean their back on. PLLC did a topographic survey for my house. They provided me with excellent customer service. I am 100% satisfied. Diana is very honest and integrity when she gave me advice what survey I should do. The crew, especially Christ, performed wonderful job. Christ has a huge knowledge and is very professional. He worked hard. He showed up early and work every minute. He has a nice attitude. He listened to my concerns. The crew left a nice work and nice behavior when they finished their job on my land. I feel very happy with the result. The cost of the survey from this company just about 75% in comparison with the other companies. I did bids. I would recommend everyone to use this company.

Working with Plog was one of the best experiences I've had recently working with any type of contractor. Diana worked hard to understand the specific requirements for our project and to produce an accurate estimate and scope of work.
Travis and Micah did an excellent job, and spent extra time to capture unique details of our property such as rockeries and garden beds. During the survey, they kept me updated on their progress and answered any questions we had. When they were done, Travis walked the property with me and pointed out existing property corners, any stakes they placed and other points of interest.
The survey drawings were delivered on time and look great. I would encourage anyone needing a landsurvey to support this family business.

Had a landsurvey done by Chris of PLOG several months back and I could not be happier with them! Great follow through despite me being on and off with the project while juggling other things, and upon meeting Chris he was a wonderful wealth of knowledge and helped to answer all my questions. The survey came back great and was filed with the county in a timely manner, and upon needing some quick edits done to the CAD file they did a great job with swift turnaround. Also they were the ONLY company that actually quoted me at a reasonable market rate for the job, all other quotes I received on thumbtack were at least $1,000 above what I should be paying, and did not offer CAD or a number of other services. Will absolutely be coming back to PLOG in the years to come. Thank you Elisha and Chris!
