It’s important you measure property lines, fence length, gate widths, and slope so you can get accurate bids; also mark underground utilities to avoid surprises and secure better pricing.
Locating Property Lines and Survey Markers
You should confirm where the property lines run and note any survey markers before requesting an estimate; moving pins can create legal disputes, so mark locations and photograph them for contractors.
Reviewing the Official Property Plat
Check the official plat at the county office to verify legal boundaries and easements; easements may limit fence placement, so you should bring a copy to your estimator.
Identifying Physical Corner Pins
Look for metal rods, rebar, or concrete monuments at corners and flag them; do not remove or alter pins, and note coordinates for contractor reference.
When pins are missing, you should check old surveys, neighbor markers, and visible fences; contacting a licensed surveyor is wise since replacing pins incorrectly risks boundary disputes and extra costs.
Calculating Total Linear Footage
Measure the full perimeter by walking each side and adding segments; include gate runs and changes in direction so your total linear footage is accurate for quotes.
Measuring Individual Perimeter Runs
Walk each perimeter run with a tape measure and note lengths; record corners, slopes, and gate openings separately so estimates reflect true material and labor needs.
Deducting for Existing Structures and Obstructions
Exclude deck, shed, and driveway widths from your total and flag immovable obstructions so contractors don’t price for replaced sections.
Note that existing posts, utility poles, and buried lines affect measurement and cost; you should mark property lines and contact 811 before digging to avoid dangerous surprises.
Accounting for St. Louis Topography and Slopes
Consider St. Louis hills and soil when measuring fence runs; you should mark steep sections, erosion-prone areas, and any utility corridors so estimates account for difficult excavation and added materials.
Determining Incline for Racked vs. Stepped Fencing
Measure the incline and note whether panels can follow grade continuously; if boards would gap, plan for stepped fencing instead of racked panels to prevent openings and post stress.
Measuring Elevation Changes Across the Yard
Walk the yard with a level or laser, marking high and low points and any drainage paths or large elevation changes so contractors size posts and order materials correctly.
Use a string line, measuring tape, and a hand or laser level to record elevations every 8-10 feet and at corners; photograph each run and flag stakes so you can show exact grade to bidders. Note any exposed utility lines, retaining walls, or major grade shifts that could increase excavation time or require engineered solutions.
Planning Gate Placement and Dimensions
Measure gate offsets and spacing before requesting an estimate so contractors can price materials and labor accurately. Mark gate centers, hinge locations, and setbacks, and note access points for vehicles and pedestrians to avoid costly change orders.
Sizing Walkway Gates for Standard Accessibility
Allow at least 36 inches clear for a standard walkway gate so you or visitors with mobility aids pass comfortably; consider 48 inches for side-by-side stroller or wheelchair access.
Calculating Clearance for Large Equipment and Vehicles
Check horizontal and vertical clearance for equipment you expect to pass through; swinging gates require swing radius, sliding gates need track length, and overhead branches or wires present a danger during deliveries.
Estimate clearance by measuring the widest equipment, including mirrors and trailer tongues, then add a safety buffer-typically 12-24 inches-so you won’t scrape or bind gates. Measure turning radius from your driveway approach, account for slope that reduces effective height, and flag any overhead wires or low branches that pose a danger; share these dimensions with your estimator for correct hinge, post, and travel sizing.
Identifying Underground Utilities and Obstructions
Check utility markers and visible signs so you can avoid buried gas lines, electric cables, and irrigation piping; document offsets and mark obstructions for estimates and safe digging.
Coordinating with Missouri One Call (811)
Contact Missouri One Call (811) before measuring so you get maps and clearance dates; you must wait for marks before digging to avoid hazardous strikes and estimate delays.
Mapping Tree Roots and Permanent Landscaping
Survey root zones and hardscape locations so you can plan posts away from large roots and protect mature trees and irrigation lines during installation.
Measure the fence path relative to tree driplines and mark roots you detect with probing or small test holes; you should avoid severing major roots, which can destabilize or kill trees. For large or protected specimens, consult an arborist and plan post placement or root-friendly anchors to preserve soil and irrigation systems while keeping your fence structurally sound.
Researching Local Zoning and Permit Requirements
Check local building codes and the municipal permit office before you ask for estimates; unpermitted work can stop your project and add costs. Contact city or county planning to confirm required permits, fees, and processing times so you can give contractors accurate timelines and avoid surprises.
St. Louis County vs. City Setback Rules
Compare St, Louis county and city setback maps so you know how far fences must sit from property lines and streets; violating setbacks can force removal. You should check for public utility easements and alley rules before contractors bid to avoid unexpected rework and fines.
Height Restrictions for Specific Neighborhoods
Confirm local height limits, HOA covenants, and historic-district rules because some neighborhoods cap fence heights or ban certain materials. Share these limits with contractors so estimates reflect compliant designs and avoid costly alterations after installation.
Many neighborhoods in St. Louis enforce unique height rules: historic districts often require design approval and written permits, suburban HOAs may cap fences at 4-6 feet, and corner-lot sightlines can limit rear or side heights. You should request zoning maps, ask about variance procedures, and factor potential waiting periods into contractor timelines to prevent delays or added costs.
Final Words
Before requesting a fence estimate in St. Louis, homeowners should take time to measure the details that affect layout, labor, and material needs the most. The most important items usually include property lines, total fence length, gate widths, elevation changes, and any visible obstacles that could affect installation. It is also smart to check for underground utilities, review setback or permit requirements, and note anything that may change the design or price of the project. The more accurate your measurements are before meeting with a contractor, the easier it is to get a more reliable fence estimate and avoid surprises later.
