What our clients say

A Google User

I hired Cardinal to do a stake survey for a fence install. They contacted me immediately after my request and performed the survey within a couple of days.

Laura Cannon Bieker

Love me some Shelly Daley Clark of Cardinal Surveying. Yesterday, she walked me through something on the phone, and today, when we could see the relevant documents, she helped me in less than 10 minutes learn how to assist my buyer.

Lucy Hauser, Lou Realty Group

Shelly has conducted numerous surveys for both my clients and I. Both her crew and her, are outstanding. They are so easy to work with and highly professional. She is by far the most knowledgeable in the business and she certainly has all of our business now and in the future!

Louis Cariffe

Very impressed with the low costs and the accuracy of this land surveying team. They quickly helped us document and present a survey to our neighbors who is where disputing my fence line and where the easements exist. Thank you for the fast help Cardinal Surveying!
