Where to Buy Andersen Patio Doors: Best Sellers

You can buy Andersen patio doors through three main channels: Andersen's own authorized dealer network (found via their dealer locator at locations. If you also want Pella options, look up where to buy Pella patio doors by comparing authorized retailers and local installers in your area. andersenwindows.com), The Home Depot (which carries multiple Andersen series in-store and online), and Renewal by Andersen, the company's full-service replacement division that handles measuring, ordering, and installation under one roof. Each channel suits a different type of buyer, and the right one depends on whether you want to DIY the installation, hire a separate contractor, or hand the entire job to one company. The biggest mistake people make is jumping straight to a seller without first knowing exactly which Andersen series and size they need, so let's start there.

Start by choosing the right Andersen patio door type and specs

Andersen doesn't sell just one kind of patio door. The product line splits into distinct series, and if you order the wrong one, the door either won't fit or won't match your existing frame system. Getting this right before you contact any seller saves real time and money.

Gliding vs. hinged: pick your door style first

Andersen treats gliding (sliding) patio doors and hinged (French-style) patio doors as entirely separate product categories, and they're sold as such. Gliding doors slide on a track and are the most common patio door replacement. Hinged doors swing open like traditional double doors and carry the Frenchwood label. If you're replacing an existing door, match the type you already have unless you're prepared for a full opening modification.

Match the right series for your opening and budget

Andersen's Patio Door Selection Guide organizes the lineup into four main families. Here's a plain-English breakdown of what each one means for a typical homeowner:

For most homeowners replacing a standard builder-grade sliding patio door, the 200 Series Narroline or 400 Series Frenchwood Gliding is the sweet spot. If your opening is non-standard or you want premium wood-clad aesthetics, step up to the A-Series or consult a specialty dealer about E-Series. Andersen publishes series-specific sizing documents (for example, the 200 Series Narroline sizing PDF includes a full table of minimum rough opening dimensions by door size), so once you know your series, you can cross-reference your actual opening before ordering.

How to measure before you talk to anyone

Andersen's help center has a dedicated article called "Determining the Size of Your Andersen Window or Patio Door" with series-specific guidance, and it's worth reading before your first seller call. The key measurement you need is the rough opening, not the visible door panel size. For replacement orders, you also need to identify your existing Andersen series if it's already an Andersen door, because the sizing designations vary by series. For custom-size A-Series or 400 Series doors, there's a unique Product ID on the identification label or etched into the glass, which Andersen uses to fulfill exact replacement parts and reorders. Grab that number before calling any seller.

Where to buy: authorized dealers, retailers, and patio-door contractors

Once you know your series, style, and approximate size, here's where to actually go buy the door. Each option has real trade-offs, and the best one depends on your situation. If you are also comparing budget-friendly alternatives like Simonton, use the same quote and verification approach when you look for where to buy Simonton patio doors.

Andersen's authorized dealer network

This is the most important channel and the one Andersen's own help center points to first. Andersen's official position is that new Andersen windows or doors must be ordered directly through a local Andersen retailer. Use the dealer locator at locations.andersenwindows.com to find authorized dealers near you. These are typically local window and door companies, building material suppliers, and specialty contractors who carry the full Andersen lineup, including series and sizes you won't find at a big-box store. They can also order custom sizes, handle non-standard openings, and often have installer relationships on staff.

The Home Depot

The Home Depot is a legitimate Andersen retailer and carries gliding and hinged Andersen patio doors both in-store and online, including 400 Series Frenchwood Gliding and Frenchwood Hinged options. You can find specific SKUs like the 400 Series White Right-Hand Frenchwood Gliding Patio Door (71-1/4 in. x 79-1/2 in.) listed with model identifiers. This is a convenient option if you want to see pricing quickly, but keep in mind that Home Depot's stock skews toward standard sizes in the 200 and 400 Series. Custom sizes, E-Series, and A-Series are generally not available through this channel. Home Depot also offers installation services, though the installer quality varies by market.

Renewal by Andersen

Renewal by Andersen is Andersen's own full-service replacement division. They sell, measure, and install their own version of Andersen patio doors (including A-Series and 400 Series lines) under a single contract. This is the turnkey option: one company handles everything from the in-home measurement to the final walk-through with the lead installer. The trade-off is that it's typically more expensive than buying a door separately and hiring your own installer. However, Renewal by Andersen's warranty can cover both the product and the installation labor for qualifying failures on products installed after January 1, 2022, which is a meaningful advantage if long-term coverage matters to you.

Specialty patio door contractors

Many local window and door contractors are authorized Andersen dealers and can source the full product line, including series that Home Depot doesn't stock. These are often the best option for A-Series custom doors, bifold configurations, or situations where your rough opening needs modification. They can also bundle measuring, ordering, and installation into a single quote, similar to Renewal by Andersen but sometimes at a lower total cost because they're competing in your local market. Always ask specifically whether they're an authorized Andersen dealer (more on verification below).

How to verify a seller truly carries and supports Andersen products

This step matters more than most people think. There are plenty of dealers who will sell you a door and claim it's "comparable to Andersen" or who carry Andersen windows but don't actually stock or order patio doors. Here's how to confirm you're dealing with a real authorized source.

1. Check the official Andersen dealer locator (locations.andersenwindows.com) first. If the seller appears there, they're authorized. If they don't, ask them directly for their Andersen dealer account number or authorization status.
2. Ask them to pull up a specific product by Andersen series and size code. A legitimate authorized dealer can look up a 400 Series Frenchwood Gliding door by its exact Andersen model identifier without hesitation. If they have to "check with their supplier" on what series you're asking about, that's a red flag.
3. Ask whether they can order custom sizes. Authorized dealers for A-Series and higher can submit custom-size orders through Andersen. If they only carry what's on the floor, they're limited to standard sizes.
4. Verify their installer's Andersen certification. Andersen's warranty documents specify that installation by an Andersen Certified Installer or Andersen Certified Contractor is required for the installation portion of warranty coverage. Ask directly: "Are your installers Andersen-certified?" A yes should come with specifics, not vague reassurances.
5. Confirm they can support post-installation warranty service. Andersen allows homeowners to register products and access warranty and parts pathways through Andersen channels. Ask whether the seller will provide the full product identifier (series, model, Product ID) needed to register the door and order future replacement parts from Andersen's parts store.

Questions to ask for quotes: measuring, lead times, installation, warranty

Whether you're calling an authorized local dealer, getting a quote from The Home Depot's installation service, or sitting across from a Renewal by Andersen rep, these are the questions that will separate a solid quote from one that'll surprise you later.

About measuring and product fit

• Will you come out and measure the rough opening before finalizing the order, or am I responsible for providing dimensions?
• Which Andersen series and specific model are you quoting, and can you show me the product identifier in writing?
• If the rough opening needs modification to fit the door, is that included in the quote or a separate cost?
• For custom-size doors: will you verify my existing Product ID (from my current door label or glass etching) before ordering a replacement?

About lead times and availability

• Is this door in stock, or does it need to be ordered? If ordered, what is the current lead time from Andersen?
• What happens if the door arrives damaged or the wrong size? What is the process and timeline for a reorder?
• Do you have any Andersen patio doors on display that I can see in person before committing?

About installation

• Are your installers Andersen-certified? If not, how does that affect my installation warranty?
• Does the installation include pan flashing at the sill and head flashing per Andersen's installation requirements?
• What is the process after installation: do I get a walk-through with the installer to verify fit, operation, and sealing?
• Is demo and disposal of my old door included, or is that an add-on?

About warranty

• What does the product warranty cover, and for how long? Is it the standard Andersen limited warranty, or a separate dealer warranty?
• Is installation labor covered under warranty, and if so, for how long and under what conditions?
• Will you provide me with the full product identifier and documentation needed to register this door with Andersen for warranty coverage?
• If I need replacement parts in the future, can I order them through Andersen's parts store using the product ID from this door?

Cost comparison basics: door price vs. install and accessories

The door price is only one piece of the total cost, and it's often not even the biggest one. Here's how the real cost breakdown typically looks for an Andersen patio door replacement.

The gap between a door-only quote and a full installed price is where most homeowners get surprised. A 400 Series door at $1,500 from Home Depot can easily become a $3,500 project once you add installation, hardware, and any opening work. Conversely, Renewal by Andersen's higher upfront cost includes the installation labor warranty, which can be worth real money if something goes wrong. When comparing quotes, make sure every quote is covering the same scope, because a low door-only quote from a dealer and a high turnkey quote from Renewal by Andersen are not directly comparable.

It's also worth noting that Andersen sits at a different price and quality point than brands like Simonton or Milgard, which tend to offer more budget-friendly options. For Milgard patio doors, you can compare local authorized dealers and big-box retailers, then confirm availability and installation options before ordering where to buy Milgard patio doors. Pella is a closer competitor on both price and quality tier. If budget is the primary constraint, it's worth comparing those alternatives before committing to Andersen.

Next steps: a quick checklist to get quotes and make the final choice

Here's exactly what to do before your first seller conversation and how to move through the process without wasting time or money.

1. Measure your rough opening (width x height) and note whether your current door is a gliding or hinged style. If you already have an Andersen door, look for the identification label on the frame or check the glass etching for the Product ID and series designation.
2. Use Andersen's Patio Door Selection Guide (available on Andersen's website) to identify which series fits your opening size, budget, and performance needs before contacting anyone.
3. Go to locations.andersenwindows.com and find 2-3 authorized dealers in your area. Also check Home Depot for quick pricing on standard 200 and 400 Series options.
4. If you want a fully hands-off replacement, schedule a free in-home consultation with Renewal by Andersen as one of your quotes for comparison.
5. Call or email each dealer with your rough opening dimensions, the series you're targeting, and the questions from the "Questions to ask" section above. Get everything in writing, including the exact Andersen model being quoted.
6. Compare quotes on total installed cost, not just door price. Confirm whether installation labor is warranty-covered, whether the installer is Andersen-certified, and what the reorder/damage process looks like.
7. Ask each seller for the full product identifier for the door you're ordering so you can register it with Andersen for warranty coverage after installation.
8. Choose the seller whose quote is clear on scope, whose installers are certified, and who will hand you proper documentation at the end of the job. Price matters, but a door that leaks two years later because of improper flashing will cost more than the difference between quotes.

The whole process from first measurement to signed contract typically takes one to three weeks if you're organized and know your series. Custom-size A-Series doors can have longer lead times from Andersen, so factor that in if you're working toward a seasonal deadline. Get your measurements done now, start with the dealer locator, and you'll have real quotes in hand faster than most people expect.
