Bespoke window treatments, motorized roller systems, and specialty interior installations involve tight tolerances and expensive custom materials. If a measurement is off by two centimeters, or if you order thirty meters of Belgian linen on credit without a client deposit, a single mistake can erase months of earnings. Here is how specialty installers package custom hardware, itemize fitting labor, and secure non-refundable material deposits before cutting.
- •Never purchase custom fabric, blinds, or motorized tracks without an upfront 50% non-refundable deposit.
- •Separate technical installation labor from hardware and fabric material costs.
- •Document electrical and structural exclusions clearly when installing motorized systems.
1. The 50% Non-Refundable Fabric Rule
Once custom fabric is cut or blinds are manufactured to millimeter window measurements, they have zero salvage value. You cannot return custom drapes to the textile mill.
Your proposal must state: '50% deposit required upon fabric confirmation and order placement. Deposits for custom cut materials are non-refundable once cutting commences.'
Always list fabric codes, pattern repeats, and fullness ratios (e.g. 2.5x fullness for S-Fold sheers) directly in the quote details.
2. Hardware Markups and Technical Labor
A heavy ceiling-recessed curtain track requires lintel anchoring, laser alignment, and ball-bearing carrier assembly. If you roll that into a generic 'installation' fee, you undercharge for precision craftsmanship.
Separate the heavy-duty aluminum track hardware from the physical installation, dressing, and on-site steaming labor.
3. Motorization & Electrical Scope Boundaries
Smart home window systems (Somfy, Tuya) are hugely popular, but customers frequently assume installers will also run 240V/110V mains wiring through drywall.
State in your exclusions: 'Certified electrical mains supply to be provided by client’s licensed electrician. Installer provides low-voltage motor connection and remote pairing only.'
