For a single glazing or pergola system, how you buy it changes what you pay and how many people stand between you and the manufacturer. Here's the actual difference between the two paths.
On a typical project, a general contractor sources the aluminum system from a supplier or fabricator, adds project management overhead and margin on top of that supplier's price, then subcontracts installation. That markup pays for real value — scheduling, coordination across trades, single-point accountability — but on a standalone project (just a pergola, just a set of sliding doors, just a facade section) you're paying for coordination you may not need.
Core Envelope is an authorized dealer for Pro Grade aluminum glazing, framing, and facade systems, and for Schildr pergolas — which means we buy and sell at dealer terms rather than through an intermediary. We handle the free site visit, design, engineering, and ordering, then connect you with a licensed local installer we trust for the physical build. You get the same manufacturer-grade system and warranty, with one fewer markup layer and one point of contact for the design and ordering side of the project.
A general contractor is genuinely the better fit when your project spans multiple trades — a full backyard renovation with hardscaping, electrical, and a pergola all happening together benefits from one party coordinating the whole schedule. For a standalone system — a pergola, a wall of sliding glass, a facade upgrade — that coordination overhead is exactly what dealer-direct removes, since there's only one system and one installer to schedule rather than several subcontractors reporting to a GC.
The manufacturer's engineering, materials, and warranty are identical regardless of how you buy — a Pro Grade or Schildr system is built to the same spec whether it's sold through a GC or through an authorized dealer. The difference is in the markup layer and the number of people between you and that spec, not in the product itself.
Yes — we connect you with a licensed local installer for the physical build; we design, engineer, and supply the system but do not perform installation ourselves.
No. Authorized dealer sales carry the same manufacturer warranty as any other sale channel — that's part of what "authorized dealer" means.
For a standalone system, usually yes, since you're removing a markup layer. For a multi-trade renovation where a GC is coordinating several different contractors, their overhead is paying for real coordination value.
In many cases yes — talk to us about your specific project and existing contractor relationships during your site visit.
