Plumbline Fence Works · Engineered fence lines · New Temperance & Foundry Falls · Lic. #FC-31882
A fence is a structure. We engineer it like one.
Plumbline designs to the numbers: post depth by the county frost line, wind loading to a 105-mph design speed, and gate hardware graded to the use it will actually get. Every line leaves our office with a one-page spec sheet you could hand an inspector.

Why lines fail
The arithmetic of standing up
Nine fences in ten that we replace failed at the post: too shallow, too loose, or set in soil the builder never looked at. The fixes are arithmetic, not craftsmanship — depth by frost line, spacing by wind exposure, concrete by hole volume — so we publish all three.
Services & rates
The 2026 rate sheet, engineered lines
Per running foot installed, posts in concrete below frost inside every number. The wind-load surcharge is its own line item, not a surprise — you will see it priced before you sign anything.
Cedar privacy, 6 ft — engineeredfrom $37/ln ft
1×6 boards, 6×6 posts at 8 ft, Exposure C spacing
Wind-load surcharge+$4/ln ft

Posts below frost, on paper
The post schedule is on your spec sheet — depth, diameter, concrete volume and spacing per exposure — signed before we dig and checked at handover with photos in your folder.
Wind loading, calculated
Privacy fences are sails. We detail to a 105-mph design speed for your exposure, which mostly means more posts and stiffer rails — priced once, argued about never.
Gate hardware, graded
Residential lines get Grade-2 minimum; anything a truck touches gets commercial cantilever rollers and keyed latches. The grade is printed on the quote.
The sequence
How an engineered line goes up
Design, then dig — never the other way round. The spec sheet exists so the crew in your yard is executing arithmetic, not improvising it.
The measurement visit
Height, exposure, setback and the slope shot with a level — the four inputs the spec sheet is computed from. Free, and yours to keep whoever builds the line.
The one-page spec
Post depth and spacing, concrete volumes, rail count, hardware grade and the wind worksheet — one page, every number, and a fixed price attached to it.
Locates & set day
811 cleared, auger to the printed depth, posts plumbed and braced in concrete mixed to the printed volume. The cure day is on the schedule before we start.
Build, gate, load-check
Rails, boards or mesh, then gates hung and self-closers set. Before we leave, every gate is opened into the wind and the line is photographed dead plumb for your folder.

Recent engineered lines
Six lines, each photographed with the spec sheet it was built from. Ask and we will send the sheet for the one nearest your road.
The windstorm in ’21 took down eleven fences on this ridge and left ours standing — I know, because I drove the ridge counting them. Plumbline’s extra posts were a line item I nearly cut, and they are now the cheapest money I ever spent.

The numbers people argue with
The four questions that decide whether a line is standing in fifteen years — answered with arithmetic rather than confidence.
Why does frost depth matter more than post quality?
Frost lifts a shallow post about an inch a year, and no bracket fixes geometry. Below the county’s 42-inch line the soil stays stable, so the post does too — which is why depth is the first line on the spec sheet and the only one we never negotiate.
What is the wind-load surcharge actually buying?
More posts and stiffer rails on exposed lines, computed to a 105-mph design speed. It adds three to five dollars a foot on ridge lots and removes the failure mode you can see leaning around the county — priced as its own line so you can decide with the numbers in front of you.
Is commercial gate hardware worth it on a house?
If it swings daily, yes: Grade-2 residential springs die in a few seasons of hard use. We quote both grades side by side, and the commercial set usually wins the five-year argument.
Cedar or composite — can you just do the math for me?
Cedar costs less to install and asks for stain every five years; composite costs roughly a third more per foot and asks for nothing. Over twenty years they land within ten percent of each other, so we quote both and let the yard decide, not the brochure.
Get the spec sheet before you get the fence.
One measurement visit, one page of numbers, one fixed price. The sheet is yours whoever builds the line — we just happen to build it exactly as printed.
