About Duley and Associates, Inc.


Duley and Associates Inc. is dedicated to providing our clients with a high quality product, reasonably priced, with fast service. We specialize in providing "rush" surveys, so that the "deal" will get to the table.

We understand, that in the often-volatile real estate market, you don't always have the luxury of giving the surveyor a couple of weeks to perform his work. We regularly turn around surveys in one to two days, sometimes even the same day, however we will never under any circumstance sacrifice the quality of our products.

We have well qualified personnel, most of which have been with us for many years. Since 1994 we have performed over 160,000 surveys. We believe we are the best at what we do and look forward to providing our clients with many more years of service.
