    Quoted $2,487.30 for a boundary survey 5/7/25. Quote said expires after 30 days. Now that it's August I realized I needed to confirm quote to proceed. Was quoted $4,840 for the exact same scope of work see pictures. When I asked Monica how this could be, she originally said the County's recording fees increased. They increased by $20... the scope of work increased by $1,619 while the description of the scope of work remained copy/pasted the same. When I pointed this out to Monica, she stated the surveyor priced incorrectly the first time. I asked for management to review and explain. I see on the May quote for the partial survey the recording fee must be incorrect since it's only $18 so there's multiple issues/mistakes happening besides the price gouging.

    Needed a property boundary survey on a large hillside residence. Reasonable prices with fast response time.

Donald was super nice and more than happy to help me. He took the time to look up my property and offer to give me a quote. Fast forward to this month when I contacted Voorheis & Voorheis for their services. I spoke with a representative who made sure to look up my property before offering me a quote for a survey. I didn't hear back from the company for 6 days. Then to add insult to injury, I was told that their company doesn't service my area, which was in glaring contrast to what Donald Voorheis told me earlier in the year, as well as the representative just recently. I'm not sure what was more disappointing, Voorheis & Voorheis' inconsistent information or the fact that it took them nearly a week to get back to me. I just wanted to share my experience. I am an Air Force veteran and this is my true and sworn testimony.
