For inside-mount factory-cut orders, the factory deducts ¼″ (one-quarter inch) from the opening width in total, not from each side. Send the opening measurement without subtracting it yourself so the deduction is applied only once. For example, a 36″ opening gives a 35¾″ finished width. Outside-mount orders have no factory width deduction. Untrimmed stock shades are supplied at their labeled width without an automatic deduction.

Measure the usable depth at the top of the window recess, allowing for window handles, stops and other obstructions. Check the complete headrail and bracket depth, not the fabric cell size. Adhesive shades also need a suitable flat surface on the casing; we must confirm their exact headrail depth before ordering.

Inside mounts fit within the window recess; measure at several positions and use the narrowest width. Outside mounts cover the opening from the face of the wall or trim. We will confirm overlap and mounting clearance for the selected product.

Custom Cordless, Simple Lift and custom Rollease / Somfy shades are made to an approved width and length before manufacture, within fabric and system limits. This does not mean they can be shortened later. Simply and No-Tool adhesive shades use stock drops with limited factory width trimming. Cut-at-Home is customer-trimmed to width using its supplied guide. Stock height cannot be shortened. Specialty shapes and skylights are made to approved dimensions or templates and need individual review.

Yes. Both the adhesive cellular and adhesive pleated shades can pull paint off the window casing when removed. In our installation experience, this happens often. Plan for possible paint touch-ups and follow the supplier’s removal instructions. Careful removal does not guarantee that the paint will stay intact.

For factory-trimmed Simply and No-Tool programs, the factory cuts a stock-size shade narrower to fit your window when we order the width-cutting service, within the product’s trimming limits. The shade arrives already cut; you do not need to trim it yourself. For example, a 36″-wide shade may be trimmed to 34″ wide where permitted. This changes the width only; the height stays at the stock drop. We arrange the width-cutting service after confirming your measurements. Cut-at-Home is different: the customer trims its width at home using the supplied guide; its length is not cut.

Send one photo per window, width and height measurements, your mount preference, quantity, preferred light control and color. For Simple Lift, include mounting depth and your preferred control side.
