Washington builders buy new construction windows in four places: a big-box store, the lumberyard, a brand dealer or showroom, or a factory-direct supplier. Each one fits a different kind of job. The big-box store is fine for a garage window in a stock size. The lumberyard is the easy default because it already delivers your framing package. A dealer earns its margin on a custom home where the plans keep moving. Factory-direct makes the most sense when your plans are final and the package is big enough that 35% matters.
Most builders end up using two of these, and that is fine. The useful part is knowing which job belongs where.
The big-box store
Every builder has walked into one for a single unit. For new construction they work best on small, simple orders: a stock-size slider for a shop, a replacement unit for a punch list, a window you need this week and can carry out to the truck.
They get harder on a full house. Stock sizes rarely match a custom set of plans, so a whole-house order turns into a special order through the store's desk, which adds a middle layer without adding much help. You also get less say over the glass package, and on a Washington home the glass package is the part your energy inspector cares about.
The lumberyard
This is where most packages go, and for good reason. The yard already does your take-offs, delivers your lumber and gives you terms. Adding windows to the same order is one less vendor to manage.
The trade-off is that the yard is a reseller. It buys from a distributor, which buys from the manufacturer, and each layer keeps a margin. The yard's window desk may also carry only one or two brands, so the product on your quote is often whatever the yard stocks. That is convenient when it happens to be the window you want. On a tight spec home it can turn into one of the priciest lines on the materials list. The full breakdown of where that money goes is in factory-direct vs distributor windows.
A brand dealer or showroom
Dealers sell one or a few national brands and keep people on staff who know them well. On a custom home with a picky owner, a designer and a plan set that changes twice before framing, that service is worth paying for. They help with sizing questions, keep samples on hand for the owner and handle warranty calls locally.
You pay for that help in the price. If your plans are already final and nobody needs a showroom visit, much of what a dealer does is service you are not using.
A factory-direct supplier
Here your window schedule goes to the factory that builds the units, with a supplier in between to handle sizing, certification paperwork, import and freight. The distributor and dealer are off the route, and their margins come off your price. On the packages we quote, the saving usually lands around 35% against the same spec through a distributor.
It asks more of you in return. The schedule has to be final when you order, because the factory builds exactly what it says. Lead time is longer than pulling from a yard: ours is eleven to twelve weeks from a locked order to the job site. Builders who order around framing start rarely notice. A builder who orders after the walls are up will. The question of whether a builder can buy this way at all, and what to ask the supplier first, is covered in can builders buy windows factory-direct?
What to compare, wherever you buy
The four routes look different, but you can hold them to the same few questions.
- Is the exact unit NFRC certified, and does the quote name the glass package that gets you to Washington's 0.30 U-factor? A brochure number is not enough. The inspector reads the label on the glass. The energy code article covers what that label has to show.
- Is every line on the quote built to the sizes on your schedule, or rounded to the nearest stock size?
- What does it cost delivered to the site, with freight and any fees in the number?
- Who replaces a unit that shows up cracked or the wrong size, how fast, and at whose cost?
- Is there a minimum order? Some factory-direct sellers only work by the container, which rules out a builder doing two or three houses a year.
If two quotes differ by a lot, the answer is almost always in one of those five lines. A cheap quote that leaves out freight, or quotes a glass package that will not pass, is not actually cheaper.
Matching the route to the job
A production or spec builder running repeat plans gets the most out of factory-direct, since the schedule is known early and the savings repeat on every house. A custom builder with an owner who keeps changing the design may be better off with a dealer, at least until the plans settle. And anyone can keep the lumberyard and the big-box store for what they do well: a single unit this week, or a pane that broke during trim-out.
