Bought a Mirador louvered pergola at Costco and now want to add accessories? Good news: you can shop compatible Mirador accessories directly at miradoroutdoor.com.
The Costco Mirador pergola is part of our 111 series. That means you should look for 111-series add-ons, like sliding shutter doors, AeroFlow louvered walls, pull-down screens, and the power strip. Just make sure the accessory size matches the side of your pergola.
One thing to know before you start: accessories and warranty support are handled in different places. You can buy accessories from us. But if the pergola itself has a missing part, damage, warranty issue, or return request, Costco handles that because the pergola was purchased there.
We'll walk through both, so you know exactly where to go and what to check.
The Costco pergola is our 111 series
Costco carries the "Mirador Adjustable Louvered Aluminum Pergola" in 10'×10', 10'×13', and 10'×20'. That's powder-coated aluminum with adjustable louvers and an integrated gutter system, built like our 111-series aluminum louvered pergolas. So when you go looking for add-ons, you're shopping the 111 accessory catalog, not a separate "Costco parts" list.
We even keep a dedicated Costco support page that links back to the exact Costco listing and points to the 111 accessory collection. If you're unsure which series you have, check the model badge or the manual that shipped in the box, then compare against the pergola's width.
Why the size detail matters: the louvered pergolas we sell, whether through Costco or our own louvered pergola collection, are standardized sizes rather than custom-cut structures. A 10'×13' has a 10' short bay and a 13' long bay, and an accessory is built to drop into one of those bay widths. There's no resizing or trimming on these aluminum panels, so the width on the box label has to match the opening you're closing off. Get that right once and the rest of the shopping is straightforward.
What you can add, and the size it has to match
Our accessories are organized by the 111 pergola accessory collection, and the page header says it plainly: "111 Accessories for 111 Pergola Collection." Each piece comes in a 10' or 13' width, so a 10'×13' Costco pergola can take a 10' accessory on the short side and a 13' accessory on the long side. Match the width of the bay you're filling, not the overall footprint.

Prices above are what we captured on-site and can move; the number at checkout is the one that counts. If a bay width or a color combination isn't obvious from the listing, email us before ordering so you don't buy a 13' panel for a 10' opening.
Practical tip: the shutter and Decowall pieces install in 1/3-bay sections, so a single 10' or 13' side often takes three panels to close it off. Plan the count, not just the width.
Missing a part or it showed up damaged?
This is where the Costco-versus-Mirador line matters most.
If a piece arrived broken or a screw bag is short on an accessory you bought from us, email support@miradoroutdoor.com with photos and we'll sort out a replacement. Open every box on arrival and photograph anything dented before you start, freight handling on large outdoor structures occasionally bends a part in transit, and documented photos make the fix fast.
For the pergola structure itself bought at Costco, missing-part claims and damage on the unit run through Costco's process, since the purchase and the warranty live there. We can answer compatibility and accessory questions any time, but we can't process a return or warranty claim on a structure we didn't sell you.
One honest caveat: we don't publish single louver blades, brackets, or end caps as standalone retail parts on the site. The 111 catalog is built around full accessory units, a Pull Down Screen, a Sliding Shutter Door, an AeroFlow wall, not a parts bin of individual hardware. If you've snapped a bracket during assembly or you're short an end cap, don't assume there's a ready SKU to add to cart. Email support@miradoroutdoor.com, describe the piece and ideally include a photo, and the team can tell you what's actually available and how to get it. We'd rather route you correctly than have you order a whole accessory unit to harvest one small part.
A quick word on weather and fit
Owners of our 111 pergolas often report the louvers staying watertight when closed and the structure holding steady in stiff wind, but that's their lived experience, not a Mirador wind or waterproof rating. If you're in a high-wind area, bolting the pergola to a concrete or paver base is the common-sense move, and the same goes whether you bought from Costco or from us. Accessories like the AeroFlow wall add side coverage but don't change the structure's anchoring needs.
A few accessories also involve drilling into the frame to mount, the Pull Down Screen is the usual example. That's worth a moment of care: follow the current installation sheet for your accessory, and if anything about the mounting points looks off for your specific pergola, ask us first. We'd rather answer a quick email than have a hole end up in the wrong spot. Once a screen or wall is on, the louver mechanism still operates the same way, so you're not giving up the adjustable-roof feature that made you buy the pergola in the first place.
Frequently asked questions

Where do I buy the accessories?
Directly at miradoroutdoor.com on the 111 accessory collection. Costco sells the pergola; the add-ons come from us.
Who handles a missing pergola part?
For a Costco-purchased pergola, missing parts and warranty claims go through Costco. For accessories bought from us, email support@miradoroutdoor.com with photos.
Can I buy a single replacement part?
We don't list individual blades or brackets as standalone SKUs. Email support@miradoroutdoor.com and describe the part so the team can advise.
How do I return the Costco pergola?
Returns on a Costco purchase follow Costco's return process, not ours, because that's the channel you bought through.
