It's the second question on almost every call, right after price: "and how long until these are actually on site?" It matters more than it sounds like it should, because a European window order sits on the critical path of the whole build - framing waits on it, the GC's schedule waits on it, and a bad guess here costs real money in carrying costs and idle crews.
The honest answer is shorter than most people assume once they hear the words "shipped from Europe." Here's what actually happens between placing an order and a crate showing up at your job site, with the real numbers rather than a padded sales estimate.
The three phases that make up the timeline
A European window order moves through three distinct stages, and each one has its own bottleneck:
- Shop drawings and approval - the fabricator draws every opening to the exact dimensions and glass build-up on your order, you (or your architect) review and sign off, and any revision cycle happens here. This step doesn't have a fixed length because it depends entirely on how fast the drawings come back reviewed - a fast turnaround is a few days, a slow one with multiple revision rounds can add two to three weeks on its own.
- Production at the factory - once drawings are locked, the factory cuts, welds or fabricates, glazes, and finishes every unit to spec. uPVC runs about 4 weeks. Aluminum runs 6-8 weeks. That gap is real: aluminum profiles need thermal-break assembly and a powder-coat or anodizing step that uPVC simply doesn't have, and specialty finishes extend it further.
- Ocean freight, customs, and inland delivery - finished units get packed into a container, shipped across the Atlantic, cleared through US customs, and trucked to your site. Into the New York metro area and the East Coast generally, budget about 5 weeks. To the West Coast, 6-8 weeks - the extra time is the longer routing plus the inland leg, not slower paperwork.
Real lead times by material and destination
Put those together and the timeline depends on two things you already know at spec stage - what material you picked and where the job is:
| Material | East Coast / NY metro | West Coast |
|---|---|---|
| uPVC | about 9 weeks | 10-12 weeks |
| Aluminum | 11-13 weeks | 12-16 weeks |
So the working range is roughly 9-16 weeks from approved shop drawings to delivery on your job site, on DDP terms (delivered, duty paid - the crate lands at your site, not at a port you then have to deal with). A uPVC package going into a New Jersey build is a different scheduling conversation than a full aluminum lift-and-slide package headed to California, and quoting both as "about four months" does nobody any favors.
Note that the clock starts at drawing approval, not at the day you say yes to a quote. Whatever your team takes to review and sign off on shop drawings sits on top of every number in that table.
What actually moves the range
The spread inside each cell comes down to a few real variables, not vague hedging:
- Order size and complexity. A handful of standard tilt-and-turn windows moves faster through the factory than a full custom home's worth of large-format lift-and-slide doors and mixed finishes. Factories batch production, and a bigger, more varied order takes a bigger production slot.
- Finish choice. Standard powder-coat on common profiles is the factory's bread and butter. Specialty finishes, anodized colors, and dual-color units add days to weeks on the aluminum side specifically - which is part of why the aluminum band is wider than the uPVC one.
- Season. European factories, like most manufacturing operations, slow down around summer holidays (July-August) and the winter holidays (late December). An order landing in a production queue right before a shutdown can add real weeks that have nothing to do with your specific order.
- Revision cycles on shop drawings. This is the one variable fully in the buyer's control, and the one that wrecks the most schedules. Every round of "can we change this dimension" after drawings are submitted resets part of the clock. Getting the window schedule right before drawings start is the single biggest lever a buyer has over the whole timeline.
What this means for scheduling the rest of the build
The practical impact is that window lead time needs to be treated as a long-lead item from day one of planning, the same way structural steel or custom cabinetry would be - not something ordered once the shell is framed and openings are sitting there empty.
The sequence that actually works: get a window schedule locked early (even a preliminary one), get a DDP price and a timeline in writing before foundation work starts, place the order once the schedule is genuinely final, and plan the rough-opening framing to match the delivery window rather than the other way around. Ordering after the framer is already standing around waiting is the most common scheduling mistake I see, and it's completely avoidable with a few weeks of lead planning.
If a project has a hard move-in date, work backward from it: pull your number off the table above, add however long shop-drawing review realistically takes on this specific team, and that's the date the order needs to be placed by.
Can lead time ever be shorter
Sometimes, at the margins. A small uPVC package in a standard finish, placed when a factory has open capacity, can land at the fast end of the range. What doesn't compress is ocean freight - air freight exists for windows but the cost is disproportionate to the time saved for anything beyond a single replacement unit, and I wouldn't recommend it as a standard strategy.
The bigger lever is material choice, and it's worth knowing at spec stage: if a schedule is genuinely tight, uPVC saves you two to four weeks of production time over aluminum before anything else is decided. That's a real trade-off to weigh against the design and performance reasons people usually pick aluminum, not a reason on its own.
The bottom line
Plan on 9-16 weeks from approved shop drawings to delivery on site, depending on material and coast - about 9 weeks for uPVC into the Northeast at the fast end, up to 16 for aluminum going to the West Coast. Treat the window order like the long-lead item it is, and lock the schedule before drawings start so the clock isn't reset by revisions.
FAQ
How long do European windows take from order to delivery? Roughly 9-16 weeks from approved shop drawings to delivery on your job site under DDP terms. Production runs about 4 weeks for uPVC and 6-8 weeks for aluminum, plus about 5 weeks of freight and customs to the East Coast or 6-8 weeks to the West Coast. The clock starts at drawing approval, not at initial order placement.
Are aluminum windows slower to produce than uPVC? Yes, by roughly two to four weeks. uPVC production runs about 4 weeks; aluminum runs 6-8. Aluminum profiles require thermal-break assembly and a separate finishing step - powder coat or anodizing - that uPVC doesn't need, and specialty finishes extend that further.
What's the biggest thing that delays a European window order? Revision cycles on shop drawings, by far. Every round of changes after drawings are submitted for approval resets part of the production clock. Locking the window schedule before drawings start is the single biggest lever a buyer has over the total timeline.
Should I order windows before the house is framed? Yes, treat the order like any other long-lead item - order once the window schedule is final, and time the rough-opening framing to the delivery window rather than ordering only after framing is ready and waiting.
