I told them there was a dispute and neighbor obtained his own survey contradicting my survey. They assured me they were correct and resurveyed again while talking to my neighbors. Turns out thanks to Prefered Survey no longer communicate with neighbor, never recieved a hard copy Survey, or even a refund or apology. Reported to better business bureau and state of Illinois guess they are as allowed to RIP you off. Do your homework and avoid this place.

I came out of my family home and discovered this strange woman and man trespassing on the property…read morewith a tape measure. When we inquired what they were doing on the property they said they were from Preferred Survey. The man indicated they were trying to get set back information for all the properties on the block for a new build at the end of the block. They were informed that this information was available on line and you could not accurately get this information with a tape measure. We instructed them to leave our property immediately. Instead of continuing their alleged work they returned to their vehicle which was strangely parked near the alley. While taking pictures of their car, the woman tried to hide from being captured in the photo and the man turned his back. We were able to secure pictures of both the trespassers and their vehicle before they abruptly left. Properties in our neighborhood are surveyed regularly but the people always have the appropriate equipment, not a tape measure. Further, I have yet to see someone trespass to get this information. I found this behavior suspect but they left before I decided to contact the police for further investigation.

They contacted Morris Engineering to try and expedite the survey to make sure we can close on time for the second time and they were able to turn out a report in less than 48 hours which was incredible. The person managing the survey, whose name escapes me, was extremely polite, honest and best of all understanding of our situation. Without their understanding and ability to expedite our survey we would most likely still be under contract. Thank you again Morris Engineering!

Inconsiderate, rude survey crew…read more A 3-person crew of young men brazenly walked down my driveway and into my backyard, telling me later they were 'entitled' to trespass on someone's property to do their survey work. BOTH our family cars were in the driveway and they did not bother to knock on our door. None of the three men had any I.D. on them. The supposed 'crew chief' was rude and stand-offish. I called the Warrenville Police, who mediated the dispute from the end of our driveway. The crew chief phoned his company owner, then handed me his phone. 'Eric Carradus' said they 'had always done business this way.' I informed him that being hired to do survey work does NOT entitle his employees to trespass on private property without even a knock on the door to ask permission. --This is 2024 and people are a lot more cautious these days, especially senior citizens like myself. The City of Warrenville verified that I "did the right thing" in calling police. Although Eric Carradus told me he would ask him employees to start asking permission to walk across private property, he would not commit to them having to carry company I.D.s (such as a gas meter reader or Amazon). From his (also) stand-offish attitude on the phone, I highly doubt that any change in company policy or behavior will be made. The Carradus crew chief guy (almost sarcastically) "apologized" to me --in front of two police officers. I told him that I accept his apology. He then (again, almost sarcastically) "asked" if his crew could enter my property to do survey work (for my next door neighbor). I said 'yes', told the police that I considered the matter resolved, and turned and went back inside. Regardless, I would urge everyone reading this review to use ANY LAND SURVEY COMPANY EXCEPT CARRADUS of Carol Stream. Their representatives were rude, inconsiderate, felt 'entitled' and carried no I.D.
