Doors and windows install locally. When the configured unit arrives with the lead, the dealer quotes the real opening instead of restarting from a blank inquiry, and deep spec content finally connects to a sale instead of ending at a PDF.
Doors & Windows
The companies that let a buyer configure and price a $40 lock have a clear next move: bring that experience to the $4,000 opening.
Stack-ranked list of Doors & Windows by composite score
Schlage treats a lock as something a buyer can configure, price, and put in a cart — a model the rest of the vertical can build on.
- Two named configurators live in the main nav. Pin & Tumbler Studio and Schlage Custom let a buyer build a finish-and-keyway combination visually.
- Every variant shows a price. $20.99 to $329 on the product page — a self-serve number that qualifies the buyer before they ever reach a store.
- Guided selling does the narrowing. A product finder plus combinable filtering walks a homeowner to the right lock, with a light AI layer that points to where the category is heading.
The three sites at the top run a complete selling flow, and their architectural lines hold the spec depth to extend it
Recommendations for Doors & Windows websites
The configurator already runs on the consumer side of these same companies. Bringing it to the architectural opening is a feature release on content that is already built, not a project from scratch.
A homeowner replacing windows budgets in ranges before calling anyone. A range qualifies the lead and shortens the dealer's cycle on a purchase that otherwise starts with a cold quote request.
The hard part is done. These companies built a configurator good enough to sell a $40 lock; pointing the same tool at a $4,000 opening is a product decision, not an engineering project.
They sell direct on the consumer side. A configurator, guided finders, and a cart let a homeowner self-serve a lock from start to finish.
The spec depth is the channel’s foundation. The same companies’ architectural lines carry deep BIM and submittal content, ready to power a configured, dealer-routed opening.
Five ways AI helps sell Doors & Windows
This is how Threekit's AI Sales Agent works: grounded in your catalog, configuration rules, knowledge base, and design content, and pointed at the way this vertical actually sells.
A contractor uploads a photo of the existing opening and the jobsite measurement form; an architect pastes a spec section. A homeowner takes a quiz instead: replacement or new construction, climate, style.
The agent recommends complete, valid units — size, glass, hardware that actually go together — explains egress and energy-code fit, and flags its confidence, so a first-timer and a specifier both get a defensible answer.
“Black exterior, tempered glass on the pair by the tub, keep everything else.” The whole opening schedule updates without re-entering a single unit.
The builder and the homeowner review the same opening schedule, and the dealer watches it settle before quoting. Nobody re-keys the order from an email thread.
Quote-ready line items, submittal-style spec sheets, and a configured order the dealer’s CPQ and the manufacturer’s ERP can ingest directly. The $4,000 opening finally sells like the $40 lock.
Make it easier to sell
This index measured where the path to a sale breaks: the handoff that arrives blank, the configurator that never reaches a quote, the seller and the dealer working from different answers. Threekit's AI Sales Agent closes that gap. It takes your catalog, configuration rules, knowledge base, and design content and turns it into an expert seller that guides your reps, your channel, and your customers to the same right answer — configured, qualified, and routed with full context. Deploy on your website, in your channel portal, or with your reps.
