Who Makes Summit Patio Doors? How to Identify the Brand

Summit patio doors are most commonly made by JELD-WEN. The clearest evidence is a warranty document titled 'Summit Window and Patio Door Lifetime Limited Homeowner Warranty' that directs all warranty claims to the JELD-WEN Warranty Dept. at P.O. Box 1329, Klamath Falls, OR 97601, and a separate Lowe's-hosted warranty PDF that explicitly names 'Summit Aluminum Products' and routes warranty assistance through JELD-WEN Customer Care. That said, 'Summit' has also appeared as a collection name under Atlantic Windows (with tiers like Summit Elite, Summit, and Summit Designer), and there is at least one Summit Building Products line warranted by Summit Specialty International LLC. So before you call anyone, you need to confirm which Summit door you actually have.

Which 'Summit' patio door do you actually have?

This is where most people get stuck. 'Summit' is not a single company selling doors out of one factory. It is a brand name that has been used by at least three distinct manufacturers, and the version you have depends entirely on where and when the door was sold. A Summit 9700 Series installation-related product description PDF exists and is hosted by the retailer All Weather at Home, showing that “Summit” can label multiple distinct series or offerings blank" rel="noopener noreferrer">Summit 9700 Series product description PDF. Here are the main Summit door lines you might be dealing with:

• JELD-WEN Summit series: The most commonly encountered Summit patio door in the U.S., including the Summit Series 8670 sliding patio door and related products. JELD-WEN's own product guide PDF lists 'Summit' as one of its named product lines. Warranty claims go directly to JELD-WEN.
• Atlantic Windows Summit Collection: A Canadian manufacturer that markets its own windows and patio doors under Summit, Summit Elite, and Summit Designer tiers. If you are in Canada or bought from an Atlantic Windows dealer, this is likely your door.
• Summit Building Products / Summit Specialty International LLC: A separate entity with its own one-year limited warranty on doors. This line is less widely distributed than the JELD-WEN Summit products.
• Summit 9700 Series: A distinct series (described in retailer-hosted technical specification PDFs from All Weather Windows) that appears to be separate from the JELD-WEN 8670 line. Multiple Summit series exist, so the series number matters.

The practical takeaway: do not assume JELD-WEN is your manufacturer just because the door says Summit on it. Confirm it by checking physical labels and paperwork first, then match what you find to the right company. If you are trying to pin down who makes silverline patio doors, you will still want to start the same way by verifying the exact manufacturer from labels and paperwork.

The manufacturers and brands behind Summit patio doors

JELD-WEN is the dominant manufacturer in this space. When it comes to MP patio doors, the manufacturer can differ by the specific brand label and model, so confirm it with the door’s paperwork and markings who makes MP patio doors. [They engineer and produce patio doors at scale across multiple brand names, and Summit is one of those names in their catalog. ](https://locations.

jeld-wen. com/mo/leessummit/the-home-depot-3026-40206. html) A forum thread on GarageJournal specifically identifies the 'Summit series 8670 sliding patio door' and traces it back to JELD-WEN, and a SWISCO parts discussion confirms the manufacturer code 'Summit Window JW-2' with a reference to JELD-WEN's AAMA standard marking. Even a warranty contact email found on a builder reseller's site reads 'summitwarranty@jeld-wen.

com,' which is about as direct a connection as you can get.

Atlantic Windows is the main alternative. They are a Canadian window and door manufacturer who uses the Summit Collection branding for their own product tier structure. If your door came from a Canadian dealer or has Atlantic Windows documentation, your warranty and parts pathway is completely separate from JELD-WEN.

Summit Building Products, operating under Summit Specialty International LLC, rounds out the picture. Their warranty covers a 12-month period from the date of shipment, which is notably shorter than the JELD-WEN Summit lifetime limited homeowner warranty. If your paperwork shows that 12-month window and references Summit Specialty International, you are dealing with a third distinct entity.

One thing worth flagging: there is a company called Summit Door that makes customized wooden sectional garage doors. That is not a patio door company. If you have seen that name in search results, ignore it for this purpose.

How to confirm your exact manufacturer from labels and paperwork

This is the step that most people skip and then regret later when they are arguing with a customer service rep who has no record of their door. Take 20 minutes to do this before you call anyone.

1. Check the corner of the glass unit: JELD-WEN's warranty documentation specifically asks for a 'window identification number found on corner of glass' or a 'spacer code.' Look at the corner of the glass pane (inside the double or triple pane unit) for a small etched or printed label. You may need a flashlight and to look at an angle.
2. Find the permanent label on the door frame or sill: Most code-compliant doors have an AAMA or NFRC certification label affixed to the frame. The Summit Series 8670, for example, carries an AAMA standard mark reference. This label often includes a manufacturer code. 'JW' in a manufacturer code points directly to JELD-WEN.
3. Look for the MFR code: The SWISCO forum thread discussing the Summit Series 8670 identified the manufacturer code as 'Summit Window JW-2.' If you see 'JW' anywhere in the code on your door, that is your confirmation.
4. Pull out your installation paperwork or original purchase receipt: The product guide, invoice, or even the box the door shipped in will name the actual manufacturer. For JELD-WEN Summit doors, the product guide PDF and warranty documents will carry JELD-WEN's name and contact address.
5. Search your model/series number online: Take your series number (like 8670 or 9700) and search it alongside 'Summit patio door.' The 9700 series appears in All Weather Windows distributor materials, while the 8670 consistently surfaces alongside JELD-WEN references. Series number plus a retailer name narrows it down fast.

If your door has no labels at all (common on older installations where labels were painted over or fell off), your next best move is to call the retailer or builder who sold or installed the door. They keep purchase records and often know exactly which manufacturer supplied their Summit-branded product. To find who makes your veranda patio doors, you usually have to check the door labels and the warranty or purchase paperwork for the actual manufacturer behind the brand name Summit-branded product.

Where Summit patio doors are sold

JELD-WEN Summit doors have appeared at Lowe's, based on the Lowe's-hosted warranty PDF that specifically names 'Summit Aluminum Products' and routes warranty claims to JELD-WEN. Home Depot has also hosted JELD-WEN warranty documents that match the Summit product identification requirements. Beyond the big box stores, JELD-WEN distributes through regional dealer networks and building supply companies, and those dealers sometimes sell Summit-labeled doors under their own store or house brand arrangements.

Fielder Builder is an example of a smaller regional reseller that reproduces the Summit warranty documentation (including the JELD-WEN warranty email) on their own site, which tells you how this works in practice: local builders and dealers buy JELD-WEN Summit products and sell them under their own branding or installation packages. Atlantic Windows sells through its own dealer network, primarily in Canada. Summit Building Products distributes through specialty building supply channels.

The practical implication: if you bought your Summit door through a local contractor, a regional home center, or a builder package, ask that contractor or store for the original purchase order. That document will name the actual manufacturer and possibly the specific model number.

Warranty, service, and replacement parts

Once you know your manufacturer, here is exactly who to contact for each Summit line:

For replacement parts on the JELD-WEN Summit 8670 specifically, SWISCO is a legitimate parts resource. Their forum has specific discussions connecting the Summit Series 8670 manufacturer code to lock and lever replacements, and their parts catalog is searchable by those codes. For hardware like lock mechanisms, rollers, and screen frames, knowing your series number before you call or search online saves significant time.

When you submit a JELD-WEN warranty claim, have the following ready: the date of original installation, proof of home ownership or original purchase, the location of the installation, and ideally the product identification number from the glass corner or frame label. Without that ID number, the process gets slower.

Replacing an existing Summit door vs. buying new: questions to ask first

Whether you are dealing with a failing Summit door or just want an upgrade, the questions you ask before committing will save you from expensive surprises. Here is what to nail down before you go any further:

• Rough opening dimensions: Measure the width and height of the actual opening in your framing (not the door itself). A consistent 1/4 inch gap around the frame is the standard target for a proper fit. If your opening is non-standard, you may need a custom-sized replacement.
• Framing compatibility: Is your existing rough opening wood-framed, steel-framed, or masonry? This affects what replacement door systems will fit without major structural work.
• Hardware and lock compatibility: If you are replacing only the door panel and not the full frame, the new hardware needs to match the existing lock prep and handle boring. Summit 8670 locks are a known replacement item, but mixing series (8670 vs. 9700) can create incompatibility issues.
• Glass options: Low-E glass, triple pane, and tempered glass options all affect both price and energy performance. Know your climate zone before choosing.
• Who is responsible for installation: Big box store purchases often mean you are arranging your own installer. Some regional dealers include installation. Clarify this upfront because installation cost can match or exceed the door cost itself.
• Is the door still under warranty: If your Summit door is JELD-WEN-made and covered under the lifetime limited warranty, a manufacturer defect may be replaceable at no cost. Do not buy a replacement before checking warranty status.

If you are replacing an existing Summit door with another Summit unit (or a comparable JELD-WEN product), ask the dealer whether the new door uses the same rough opening dimensions and framing attachments as your current one. Staying within the same manufacturer family often makes the replacement cleaner and cheaper.

Cost and installation: what to expect by door type and material

Summit patio doors span sliding, French, and occasionally bifold configurations, and the cost varies significantly by type and material. If you want to know who makes masterpiece patio doors, the right approach is to identify the exact manufacturer name on your label and paperwork first Summit patio doors span sliding, French, and occasionally bifold configurations. Here is a realistic breakdown to set your expectations:

Aluminum Summit doors (like the Summit Aluminum Products line) are typically the most affordable entry point, and the one-year warranty on that line reflects the more budget-oriented positioning. If you are in a cold climate, pay close attention to the thermal break (or lack thereof) in aluminum frames. A thermally broken aluminum frame costs more upfront but prevents condensation and heat loss that becomes a real problem in climates with sustained freezing temperatures.

Installation costs are where people consistently get surprised. A basic sliding door swap where the rough opening is already the right size and in good shape will run on the lower end. But if you are dealing with rot in the sill, a rough opening that needs to be reframed, or a masonry opening that needs cutting, costs climb quickly. Always get at least two installation quotes and ask each installer to walk you through what they are assuming about your existing framing before they give you a number.

If you are comparing Summit to other store-brand or builder-grade patio door lines (similar to how Reliabilt, Silverline, MP, Veranda, and Masterpiece are distributed through major retailers), the approach is the same: the brand name on the door often reflects the retailer or reseller, not the factory. If you are specifically wondering who makes Reliabilt patio doors, the same rule applies: the brand on the label can point to the retailer or reseller rather than the original factory. The real manufacturer determines the warranty, the parts availability, and the long-term support you can expect. In Summit's case, JELD-WEN is the most likely manufacturer, and that is actually a good thing: JELD-WEN has a broad parts and service network, a verifiable warranty department, and decades of production history behind those doors.

Your next steps right now

1. Go look at your door today and photograph any labels on the frame, sill, or glass corner. Note any codes that include letters like 'JW.'
2. Pull your original purchase paperwork or call the retailer/builder who sold the door and ask for the manufacturer name and model number.
3. Match what you find to the correct Summit manufacturer line using the table above.
4. If it is a JELD-WEN Summit door: contact [email protected] or write to their Klamath Falls address with your product ID and installation date before spending money on repairs or replacement.
5. If you need replacement hardware or parts: search your series number (8670, 9700, or other) on SWISCO alongside the manufacturer code from your label.
6. If you are buying new: measure your rough opening, decide on material (aluminum, vinyl, or wood-clad), and get at least two quotes that include installation so you are comparing total cost, not just door price.
