Why Lenze
A survey is a legal document. It should be treated like one.
A survey map ends up in a closing file, a permit application or, occasionally, a courtroom. That is why every job here follows the same discipline — records first, field measurement second, and a licensed review before anything is sealed.
- Licensed and accountable Gerard D. Lenze, Professional Land Surveyor, New York State license number 051099. The license number appears on every map issued.
- Records before measurements Deeds, filed maps, tax maps and prior surveys are researched before the crew rolls, so field evidence is checked against the record — not the other way around.
- Modern instrumentation Robotic total station and GNSS observations, redundantly measured and adjusted, then drafted in CAD to a clean, readable standard.
- Deliverables that get accepted Sealed PDF and printed copies formatted the way Long Island building departments, title companies and lenders expect to receive them.
How it works
Four steps from phone call to sealed map.
Most residential surveys follow the same path. You will know the scope, the fee and the expected turnaround before any work begins.
STEP 01
Scope and quote
Tell us the property address and what the survey is for. You get a written fee and a realistic schedule — no hourly surprises.
STEP 02
Research
Deeds, filed maps, tax maps and any prior surveys are pulled and reviewed before fieldwork is scheduled.
STEP 03
Field survey
Monuments, improvements and grades are measured on site. Most residential lots take a single visit of a few hours.
STEP 04
Map and seal
Data is reduced, drafted and reviewed, then issued signed and sealed as a PDF with prints on request.
From the field
What the work actually looks like.
Photographs from our own jobs, not stock images. A survey comes down to small decisions made on the ground: which monument to believe, where a corner truly falls, and how to mark it so the next person can find it.

About
Gerard D. Lenze, Professional Land Surveyor.
Gerard Lenze was born and raised on Long Island, and he still lives here — in Massapequa, with his family. The towns on the service-area list are not a marketing radius drawn on a map; they are the neighborhoods he grew up in, drives through every week and knows street by street.
He came up through the field, running survey crews and construction layout long before licensure, which is why the maps are drawn by the same person who has stood on the corners and set the monuments. He founded Lenze Land Surveying, D.P.C. in 2023 to do one thing well: produce accurate, defensible surveys with direct accountability to the client, and he is a member of the New York State Association of Professional Land Surveyors (NYSAPLS).
That local knowledge matters more than it sounds. Long Island records run deep and uneven — filed maps from the subdivision booms, hand-written deed descriptions, stone walls and hedgerows that were treated as lines for a century. Knowing how a particular village keeps its records, and what the surveyors before you tended to do, is often the difference between a clean answer and an argument.
“A property line is not an opinion. It is evidence, measured carefully and documented so it holds up years later.” Gerard D. Lenze, P.L.S. · License 051099

Common questions
What most callers ask first.
Can I use the old survey from when I bought the house?
Sometimes, but not always. Lenders, title companies and building departments usually want a survey that reflects current conditions, and anything built, removed or fenced since the old map was made is not shown on it. An existing survey is still useful — bring it, and it may reduce the research needed.
How long does a survey take?
For a typical residential lot, expect record research and scheduling first, a field visit of a few hours, then drafting and licensed review. Turnaround depends on how complex the record is and current workload — you will be given a realistic date with your quote, and rush work can often be accommodated.
What does a survey cost?
Fees depend on lot size and shape, the age and clarity of the record, how much of the property is obstructed, and the type of survey required. Every job is quoted in writing up front — call or send the property address and the purpose of the survey and you will get a firm number rather than a range.
My flood insurance premium jumped. Can you help?
Yes. A FEMA elevation certificate documents your building's measured elevations relative to the base flood elevation, which is what an insurer uses to rate the policy. In some cases the certificate supports a Letter of Map Amendment to remove a structure from a mapped flood zone.
Can I send you my old survey or deed?
Please do. Attach a prior survey, deed, title report or filed map to the quote form below, or email it to lenzelandsurveying@gmail.com. Even an old or faded copy is useful: it identifies the record description and the monuments a previous surveyor set, which often shortens research and reduces the fee. A phone photo of a paper copy is fine.
My neighbor and I disagree about the property line. What now?
A licensed boundary survey is the starting point. Record evidence and physical monuments are researched and measured, and the findings are documented on a sealed map that can be relied on by both parties, their attorneys or a court.

Tell us where the property is and what the survey is for. You will hear back from the licensed surveyor — not a call center — with scope, fee and timing.
If you already have an old survey, deed or title report, send it along. Prior documents often shorten the record research and lower the fee.
