A client texts: “Can we do drapes and motorized shades too?” And just like that, you are juggling fabric lead times, motorization specs, install calendars, and the one detail nobody warns you about early enough: who is actually responsible for measuring the windows.
That question came up directly in the Interior Design Community: “What company does everyone use for drapery and blinds?” It sounds like a vendor request. The more useful answer is a framework for choosing the right window treatment partner for each specific project, because the right vendor for a clean new build with decisive clients is rarely the same vendor you want on a historic renovation with custom plaster returns and a client who changes their mind.
The real goal is a repeatable way to evaluate and match partners to project needs, then document who owns what so nothing falls through before install day.
Three Types of Window Treatment Partners
Before you pull up your vendor list, sort the project into one of three categories. That sorting decision drives everything else.
A custom workroom is the right call for elevated drapery work: tricky windows, specialty pleats, interlining, layering, full design control, and situations where the fabrication quality is visible, and client expectations are high. These relationships tend to be regional and rely heavily on your local knowledge of who does the work well.
A shade and blind specialist is built for roller shades, woven woods, Romans, and motorization, particularly when you need clean measurement protocols and a tight install process. The best trade programs in this category run end-to-end: they measure, fabricate, and install, which removes a significant coordination burden.
A hybrid partner handles both shades and soft goods under one roof, which is useful when you want fewer handoffs and fewer “that’s not our scope” conversations during installation.
@paigegarlandinteriors runs this split naturally: “Skyline! They have gone above and beyond for us in the past for shades, love our local workrooms for drapery like @sophosco if you’re in the Chicago area.”
That distinction, different vendors for different product categories within the same project, is one of the more practical approaches in the community. It trades a little coordination complexity for significantly higher quality control on each category.
Five Questions Before You Recommend Anyone
Vendor reputation is a starting point. The service model is what actually matters on a project. Before you bring anyone into a client engagement, get clear on these five things.
Who measures, and who owns the liability if measurements are wrong? This is the single most common source of window treatment problems on projects. Some trade programs measure themselves and absorb the remake cost if they are wrong. Others defer measurement to the designer or a third party. Know exactly where that accountability sits before the order is placed.
Who fabricates? In-house workrooms and outsourced fabrication have different lead times, quality consistency, and ability to accommodate changes. Get typical lead times by product type, not a general range.
Who installs? And do they handle punch work, returns, and rehangs as part of the scope, or are those separate conversations?
How do they communicate? One point of contact, written quotes, and a clear approval process are non-negotiable on full-service projects. Vendors who operate informally tend to create documentation gaps that surface at the worst possible moment.
What is the trade service model? Trade pricing structure, markup expectations, and whether they support white-glove client experiences should all be confirmed before you commit to a relationship.
@david_michael_interiors described what the end-to-end model looks like in practice: “We Measure/Fabricate/Install all of what we sell. We have our own workroom, all in house. We service NY/Long Island/Westchester/Connecticut. We also opened a showroom in Florida.”
That integrated model, one team owning every step, reduces the accountability gaps that cause most window treatment problems. Not every market has it, but when you find a vendor that operates this way, it significantly reduces the coordination load on the designer.
Matching Vendor Type to Client Expectations
The project scope and client profile should drive vendor selection as much as the product category does.
For detail-driven clients who want to discuss headers, lining weights, returns, stackback, and hardware in depth, lean on the custom workroom. You want a team that can have that conversation without guessing, and whose fabrication quality can stand up to close inspection.
For timeline-driven clients in which a clear install date matters more than custom fabrication details, lean toward a shade specialist or a hybrid partner. Speed usually comes from a tight measure-order-install workflow with fewer variables, and shade-forward programs tend to have that discipline built in.
For clients who want one point of contact and minimal decisions, a hybrid partner who can own the full scope, soft goods plus shades, reduces your coordination role and gives the client the “one and done” experience they are asking for.
@ggemdesign described her approach: “We work with local workrooms wherever we are. Some of the panel programs are getting very good though!”
That observation is worth noting. The national panel programs have improved meaningfully in quality and trade support over the past several years, and for certain project types, they now compete credibly with regional workroom relationships that took years to build.
Scripts for the Measurement and Timeline Conversation
Three short scripts that prevent the most common window treatment scope problems.
On measurement responsibility: “For window treatments, measurements drive everything. Our process is that the window treatment vendor measures and owns measurement accuracy, then we approve the quote and finalize finishes before ordering.”
On splitting drapery and shades between vendors: “We can absolutely do both drapery and shades. We will source the right partners for each, because motorized shades and custom drapery are different specialties. This protects your budget and keeps the installation smooth.”
On custom lead time expectations: “Custom window treatments are made to order, so lead time includes fabrication plus scheduling install. We will confirm dates after measurement and final approvals, and we will not promise an install date until the order is placed.”
That last script handles more client conversations than almost any other window treatment topic, because the gap between “can we get these by the reveal?” and what fabrication actually requires is where most timeline friction originates.
Build Your Vendor Bench Before You Need It
The designers who handle window treatment scopes most efficiently are not the ones who start researching vendors when a client asks. They already have a bench.
A useful starting point is one shade specialist, one custom workroom, and one hybrid partner per metro area where you work regularly. From there, track what each vendor is actually good at: motorization, woven woods, high ceilings, tricky bay windows, and quick turns. Log the operational details that matter to your process: deposit terms, communication style, quote turnaround, and install quality over time.
@skyline.nashville described how their trade program was built: “We are a mom and pop. 50 employees across all markets. We do all shades and have a custom soft-goods workroom. We have a high-touch trade program that I created based on my 30 years of experience in the business.”
That kind of institutional knowledge in a vendor relationship is what makes a trade program genuinely useful rather than just available. When you find partners with that orientation, the relationship is worth maintaining carefully.

What to Document Before the Order Goes In
A short checklist that catches the issues that show up most often between quote approval and install day.
Confirm the full product scope in writing: drapery, shades, blinds, hardware, and motorization. Clarify who measures and who owns measurement accuracy. Confirm COM versus vendor-supplied fabric, lining specifications, trim, and yardage requirements. Document lead-time assumptions and the installation scheduling process. Confirm the deposit and payment schedule. And establish, in writing, what the warranty, remake policy, and billable site-visit terms are.
That last item matters more than designers expect. What counts as a billable return visit varies significantly by vendor, and sorting it out after installation is harder than sorting it out before the order is placed.

The Vendor Makes the Category
Window treatments are one of those categories where the right vendor relationship makes the work feel effortless, and the wrong one creates compounding problems through measurement, fabrication, and installation. The framework is not complicated: sort the project by scope, ask the five questions before you commit, match vendor type to client expectations, and keep the documentation ahead of the order.
The community names its favorites for a reason. Build your own bench from the ones that match your market and your process, then standardize how you engage them so every window treatment project runs the same way.
