Custom vs Stock Blinds in Pittsboro: What Actually Differs

Plenty of advice about window coverings treats stock product as something to avoid. That is not honest. Stock is well made for what it is, and in some rooms it is clearly the right purchase. The trouble starts when a product built to a fixed size meets an opening that is not one. This is a room by room guide to where each answer belongs in a Pittsboro house.
What Happens When a Stock Blind Gets Cut to Fit
The most common mistake in this category is assuming a cut down stock blind and a custom blind are the same product with a different price tag. They are not, and the difference is mechanical, not cosmetic. A stock blind is built to fixed sizes and then trimmed at a store, usually to the nearest eighth of an inch, after the mechanism inside has already been assembled for a different length.
That trim moves things. The tilt mechanism ends up sitting closer to the end cap than it was designed to. The ladder strings that hold each slat level do not move at all, since they were spaced for the original width, so a length of slat near each end can hang past the last one with nothing underneath it.
The mistake is not buying stock. Stock is a fine product within its assumptions. The mistake is assuming a cut down blind will behave exactly like a factory built one over the years, when the geometry underneath it changed the moment the saw ran.
What a Proper Measure Actually Checks
A full measure runs about an hour for a whole house, and it follows the same sequence every time because the sequence is what catches the problems. Width first, at both ends of the opening and at the middle, with the narrowest reading governing an inside mount. Height next, at both ends and at the center, with the shortest reading governing there.
Diagonals get checked for square, and mounting depth gets checked against the minimum the product needs, since a shallow opening rules out an inside mount before fabric gets discussed. Obstructions get noted on the spot: a crank that swings into the shade's path, an alarm contact in the wrong place, a sill that is not flat.
Control side and roll direction get settled on site too, along with stack height, since those are decisions much easier to make looking at the actual window than guessing from a floor plan later. A Pittsboro house with a dozen openings typically produces two or three spots that need a judgment call, and that is normal, not a sign anything is wrong with the house.
Warranty, Remakes and Who Pays If It's Wrong
The room level decision has a warranty consequence worth knowing before it becomes a surprise. Stock cut at a store is generally a final sale, so ask about the return policy before the saw runs, since a mistake there is the buyer's to fix.
On a custom order, the company that measured owns the numbers, and a remake caused by a bad measurement is on them. That is a fair, direct question to ask before signing in any room, not just the expensive ones: if this comes back wrong, who pays to fix it?
The manufacturer's warranty and the seller's warranty on labor and fit are two different documents, and a cut down stock blind often has the trimmed dimension excluded from the first. That is reasonable to accept in a basement and less reasonable in a room that took real thought to plan. IN law requires a written contract for residential work over $150, with a scope and a total price spelled out, under IC 24-5-11, and that is where mount type and lift type for every opening belong.
Most blind buying mistakes are avoidable once you know what to check. The diagonals and the mounting depth matter most, along with a plain answer on who pays for a remake if a number turns out wrong. Pittsboro Window Treatments walks Pittsboro homeowners through all of it before an order goes in, insured and bonded, so the surprises show up during the measure instead of after installation.

Where Stock Makes Sense and Where It Doesn't
Stock is not a lesser product built down to a price. It has one fixed assumption built into it: that a Pittsboro opening matches a size somebody chose in advance. Nationally, stock window coverings run roughly $60 to $600 a window, while custom, measured in the home and installed, runs roughly $250 to $2,600. Where that assumption holds, stock is a genuinely good buy.
It holds up in a garage, a laundry room, a basement, an unused guest room, or a rental between tenants. Those spaces share low cycle count: a blind adjusted twice a season never gets worked hard enough to notice that its ladder strings were spaced for a different width.
The assumption breaks down on wide openings, which need a heavier headrail or a center support most stock lines do not offer, and on tall openings, where the usual fix is letting excess pile on the sill. Out of square openings and bedrooms that need real darkness belong on that list too, and so does anything motorized, since a motor has to be matched to a shade rather than bolted on afterward.
Why Openings Are Rarely Perfectly Square
Squareness is not something to assume your way past, and skipping the check is one of the more expensive mistakes in this category. Framing settles over the years, and an opening that left the factory square is not guaranteed to still be square by the time anyone orders a blind for it. A real measure checks both diagonals for exactly that reason.
The cost of getting this wrong is not abstract. A stock rectangle sized to the widest point of an out of square opening binds at the narrowest point, usually meaning a fight with the blind every time it operates. Sized to the narrowest point instead, it leaves a visible wedge of daylight that gets wider toward one end, with no fix for that after the fact.
Custom pricing absorbs this risk in a way stock pricing does not, because the factory works from your opening's actual numbers rather than a standard size. This shows up often in older Pittsboro homes, and just as often in additions and rooms above a garage, worth budgeting for custom.
Frequently Asked Questions
What actually happens when a store cuts a blind to size?
The headrail, the tilt rod, the bottom rail and every slat get shortened, usually to the nearest eighth of an inch. The tilt mechanism ends up sitting a different distance from the end cap than the design intended. The ladder strings that hold the slats level stay where they were, so several inches of slat can end up hanging past the outermost ladder with nothing supporting it. That unsupported length is what sags over time.
How do I know if my openings are out of square?
Measure both diagonals, corner to corner. If the two numbers match, the opening is square. If they differ, it is not, and the difference tells you by how much. It also helps to check width at both ends and the middle, and height at both ends and the center. A noticeable difference between those readings tells the same story.
Is custom worth it for every window in the house?
No. Custom earns its cost on wide or tall openings, out of square openings, bedrooms that need real darkness, and anything motorized, plus every window visible from the street. Stock is the sensible answer in a garage, a laundry room, a basement, or a guest room used a few times a year. Most well planned projects use both, with the money concentrated where people actually spend time.
