DeKalb is the largest city in DeKalb County and a regional hub whose university presence and commercial corridors keep new construction active across town. When a project finishes, a final as-built survey records the true location and elevation of what was built so it can be measured against the plans the city approved. That comparison is what lets closeout proceed with confidence that construction matched the design.

DeKalb & DeKalb County specifics

DeKalb has a population of roughly 40,290 and sits within DeKalb Township in DeKalb County, whose county seat is Sycamore. The South Branch of the Kishwaukee River runs through the area, so new development often carries grading and drainage conditions a city engineer expects verified before final acceptance. A final as-built survey documents constructed elevations and improvement locations against the approved plans, supporting that engineering review at closeout. Survey plats and related documents are recorded through the DeKalb County Recorder / Clerk & Recorder in Sycamore.

What DeKalb-area clients say

I've used Pi Surveying a few times (once in the sale of my home and another in the purchase of my current home) and have to say I'm extremely satisfied with the service they provided. They were extremely detail oriented, experienced, and delivered an exceptional survey with very little effort on my part! From first call to job completion, they were always available and very communicative. Will definitely be calling them if I need them again!

This service is superb! I needed a survey done quickly. I had a deadline and I was out of options. Someone referred me to Pi Surveying and they were so easy to work with. They were competitively priced, quick to get the job done and reliable. Their customer service is top notch! I highly recommend!

Pi Surveying delivered exactly what we needed, on time and without any hassle. From the initial call to receiving our final survey documents, the process was smooth and straightforward. You can tell this team knows what they're doing — over 40 years of combined experience really shows in the quality and accuracy of their work. Highly recommend to anyone in the Chicagoland area!

We were very happy with the services provided by Pi Surveying. They came out quickly for a survey that I needed to get in order to put up a fence on our property. We were in a rush because the HOA would start fining us if we didn't get it done before the end of the month. They were awesome! Very highly recommend this company.

Pi Surveying helped me in the process of buying my commercial building. As a first time buyer, they were very helpful and efficient in taking care of the surveying part. My point of contact was very responsive and I would definitely recommend them and use them again. Great overall experience.

My wife and I were pleased with the Land Surveying services that Pi Surveying provided. The surveyor took the time to explain everything on the survey and what our property boundaries looked like legally. They were professional, courteous and efficient throughout the entire process. We highly recommend them!

Found myself in a bind after discovering some issues with a property. My real estate attorney pointed me towards Pi and I will do the same for anyone else! They were able to get me taken care of when I was in a time crunch, and didn't rake me over the coals with pricing. Standup company, honest, and have earned my business for life. Thanks guys!
