Is It Safe to Send My Own Window Sizes for a Quote in Malibu and the Westside?

Sending your own sizes and photos is perfectly fine for getting a quote, and for a lot of simple openings it is fine for ordering too. The risk shows up when the numbers become the manufacturing order: if a shade or shutter is built to a measurement you supplied and it does not fit, the remake gets charged to you, and a professional measure is the only thing that moves that risk off your side of the table.

What a remote quote does well, and where it stops

We quote remotely all the time. A homeowner in Santa Monica or Redondo Beach sends a spreadsheet of rough sizes and a photo of each opening, and we can price the job closely enough for a real decision — product, fabric family, mount type, motorization or not. That is what most people actually want early on. You can also run a competing bid through Quote Check and see how the line items compare.

Where it stops is the order. Custom window treatments are cut to a fraction of an inch and there is no adjustment afterward. A roller shade fabric panel is cut once. A shutter frame is welded or joined to a fixed outside dimension. Nobody at the factory is checking your arithmetic against your house.

That matters more here than in a lot of markets. The housing stock across Malibu, Pacific Palisades, Brentwood and Beverly Hills is heavy on floor-to-ceiling glass, tall stacked sliders, and rebuilt or remodeled openings where the drywall return, the stucco edge, and the window frame do not agree with each other. Those are exactly the openings where a single tape-measure number is least trustworthy.

The six mistakes we see most in homeowner measurements

These are in rough order of how often they cost somebody money.

• Inside mount versus outside mount never got decided. An inside-mount measurement is the opening itself. An outside-mount measurement is the opening plus however much overlap you want on each side, and it depends on what the wall around the window can accept. The same window can be 47 1/2 inches or 52 inches depending on which you meant. If the order form says "inside" and your number included overlap, the product arrives too wide and will not go in.
• Measuring once instead of three times. Width gets measured at the top, the middle, and the bottom of the opening. Height gets measured at the left, the center, and the right. On a square opening the three numbers match and you are done in ten seconds. On an out-of-square opening they do not, and the difference is the whole story.
• Applying your own deduction. Homeowners who have read a how-to page sometimes subtract 1/4 inch or 1/2 inch "for clearance" before sending numbers. Every factory applies its own deduction to a raw inside-mount size. Subtract first and the deduction happens twice, and you get a shade with a light gap down both sides. Send the raw opening and say plainly that it is the raw opening.
• Rounding fractions. Round 30 7/16 inches up to 30 1/2 inches on an inside-mount roller shade and you have removed your clearance. Factories work in 1/8 inch, and the honest practice is to record the nearest smaller 1/8 for width and never round up. Decimals are worse — 30.5 typed into the wrong field has come back as 30 inches more than once.
• Forgetting depth. Inside mount needs a pocket. A shutter frame, a roller shade bracket, a cellular headrail, a zebra cassette, and a motor tube all need different amounts of it. A tight stucco return in a Venice or Marina del Rey unit may have 1 1/2 inches of usable depth, which rules some products out entirely. Depth almost never appears on a homeowner's list because nothing about measuring width and height suggests you need it.
• Obstructions that only matter after install. Crank handles on casements, slider latch handles, alarm contacts, pulls on French doors, a tile sill that projects past the frame, an ocean-facing slider with a recessed track. The window measures fine. The product then hits the handle every time you close the door. This is the single most common cause of a treatment that technically fits and still has to come back off the wall.

Out-of-square is the coastal norm, not the exception

Older beach construction moves. Houses on Malibu Colony and along The Strand in Manhattan Beach have settled on sand, been re-stuccoed, had windows swapped inside existing rough openings. Hillside lots in Santa Monica Canyon, Topanga, and Trousdale Estates have their own history of movement. And rebuild-era work anywhere on the Westside often leaves a drywall return that is straight to the eye and 3/8 inch off from top to bottom with a level on it.

An opening that is 46 1/8 inches at the top and 45 3/4 inches at the bottom is not a measuring problem, it is a product-selection problem. For an inside-mount shade the narrowest number governs, and you accept a wider light gap at the top. For shutters there is a real choice between a frame that hides the discrepancy and a hangstrip that does not. For a Point Dume view wall with four openings in a row, there is also the question of whether they should all be ordered to the same size so the reveals read straight across the wall, which is a decision no measurement sheet asks you to make.

None of that is exotic trade knowledge. It is just the part of measuring that is judgment rather than arithmetic, and it is the part that does not survive being emailed.

Who pays when a product is built to a wrong number

We will be plain about this, because vague policies are where bad surprises live.

If you supply the measurements and we order from them, and the product comes back the wrong size because the measurement was wrong, the remake is charged to you at our invoiced cost from the manufacturer, with no markup added. We do not absorb it. We also do not profit from it. You pay what the factory charges us to build the part again, and we reinstall it.

If we measure and the product does not fit, that is ours. We remake it and reinstall it at no cost to you. That is the actual difference a professional measure buys — not a more accurate tape measure, but a transfer of responsibility.

Worth saying: a remake is rarely catastrophic on a single shade. On a twelve-opening order where the same error repeated across a whole wall of glass, it is a number that stings. The pattern shows up in the complaints people leave online about custom window covering orders generally — we went through a pile of those, and "it didn't fit and then we argued about whose fault it was" is near the top.

So which openings can you measure yourself?

Reasonable candidates for self-measurement, if you want to move fast on a small job:

• Outside-mount blinds or shades on a flat wall with generous room around the opening, where an extra 1/4 inch does no harm.
• Newer construction with clean drywall returns that measure identically at top, middle, and bottom.
• Drapery, where the rod placement is a design decision and the panel width has tolerance built into the fullness.

Openings we would not order from a homeowner's numbers:

• Any inside-mount shutter. Shutters are the least forgiving product we sell, and the frame has to live inside a real, slightly crooked hole.
• Sliders and French doors with handles, and anything where the treatment has to clear moving hardware.
• Tall or stacked ocean-facing glass where motorization is on the table — motor and bracket clearances are product-specific, and the whole wall has to line up visually.
• Arches, angles, corner windows, and anything with a tile or stone sill.

If your list is mostly in the second group, the measure visit is the cheaper path even before you count the risk. Someone comes to the home, measures every window, brings real samples so you can see fabric openness and shutter louver widths against your own glass and light, and you get a firm quote. The in-home consultation is free. You can book that visit here, or send sizes and photos and we will tell you which openings we are comfortable ordering from and which ones we are not.

And if you are still collecting bids, read the quotes line by line for who is responsible for measurements. It is usually in there, in small type.

Frequently asked questions

Can I just send my own measurements to get a quote?

Yes. Rough sizes and a photo of each opening are enough to price a job closely, including product, fabric, mount type, and motorization. The caution is about ordering from those numbers, not quoting from them. We will tell you which openings we are comfortable manufacturing from a homeowner measurement and which ones we would rather measure ourselves.

If I measure and the shade comes back the wrong size, who pays for the remake?

You do. If we order from measurements you supplied and the product is built wrong because the measurement was wrong, the remake is charged to you at our invoiced cost from the manufacturer with no markup added. We do not absorb it and we do not make money on it. If we measured, the remake and reinstall are on us at no cost to you.

How many times should each window be measured?

Width at the top, middle, and bottom of the opening; height at the left, center, and right. On a square opening the numbers match. On an older beach or hillside house they often do not, and the difference between them decides the mount type and sometimes the product. Record to the nearest smaller 1/8 inch, like 30 3/8 inches, and never round up.

Should I subtract clearance from my measurements before sending them?

No. Send the raw opening size and say clearly that it is the raw opening and whether you want inside or outside mount. Every factory applies its own deduction to an inside-mount size. If you deduct first, the deduction happens twice and you end up with visible light gaps on both sides.

Why does depth matter for an inside mount?

Every product needs a different pocket. A shutter frame, a roller shade bracket, a cellular headrail, a zebra cassette, and a motorized tube all require different clearance from the glass to the front edge of the opening. A shallow stucco return can rule out some products entirely, which is why depth belongs on the measurement sheet alongside width and height.
