Andersen Window Installation: The Wellington Owner’s Guide

Andersen window installation in Wellington typically runs $75 to $160 per window for a standard single-hung or double-hung unit, and most installs are completed the same visit. That price includes removing the old window, setting the new Andersen unit, leveling and squaring the opening, insulating the gap, and sealing both sides against South Florida rain. We carry Andersen-compatible hardware, sash replacements, and full-frame inserts on our trucks, so if your window has a cracked sash, a failed balance, or rotted wood at the sill, odds are we fix it on the first trip.

The way most Wellington homeowners find us is after a storm or a hard summer: a window stops closing square, the sash drops like a rock when you unlock it, or a hairline crack finally spreads across the glass. Sometimes it’s simpler than that. A homeowner leans on the frame to open the blinds and feels give at the bottom corner. That’s rotted framing, and it happens in Wellington more than people expect because of our humidity and afternoon downpours. If you catch it early, you’re replacing a sash. If you wait, you’re replacing the frame and maybe the rough opening.

We’re an independent service provider, not an Andersen-owned operation. That matters because we tell you straight when an aftermarket part performs every bit as well as the OEM unit and when it doesn’t, without a factory script pushing you one direction.

Key takeaways:

• Most Andersen window installations in Wellington cost $75-$160 per window, installed same visit.
• We stock Andersen OEM and tested aftermarket parts on the truck, not in a warehouse two weeks out.
• Both manufacturer warranty layers get registered in writing the day we install, per The Keystone Standard.
• Workmanship is covered by our Done Right Promise, no fine print.

Which Andersen Models This Applies To

We install and service Andersen’s full residential lineup: the 100 Series, 200 Series, 400 Series (including Woodwright and Tilt-Wash), E-Series/Eagle, and A-Series. In Wellington, the 400 Series is the one we see most often in homes built from the mid-1980s through the early 2000s, and the 100 Series shows up constantly in newer construction and HOAs that mandate a fiberglass or composite frame. The 200 Series, with its vinyl cladding, appears more in entry-level to mid-range builds from the 1990s.

Here’s the compatibility gotcha most people don’t know until they’re standing in front of a broken window: Andersen changed the balance shoe design between the 400 Series Tilt-Wash and the newer 400 Series Woodwright, and the parts are not interchangeable. If you read the glass etching or the sticker in the corner of the window, you’ll see the series and sometimes the manufacturing date. But the etching only tells you part of the story. The balance shoe, the hinged wash assist, the weatherstripping profile: these vary by production year, not just series. We measure the part, not just the label. It’s one more reason Dale Kessler insists on measure-twice discipline.

On the OEM question: Andersen’s own parts are good, and we quote them when the warranty still applies or the application calls for it. But for a 20-year-old 400 Series Tilt-Wash that’s no longer under warranty, we often recommend a tested aftermarket balance shoe and pivot bar from a supplier we’ve used for years. Same fit tolerance, half the price, and we’ve installed enough of them to know they hold up in Florida humidity. We show you both options on paper before we touch a screwdriver.

Signs Your Andersen Window Installation Is Failing

• The sash drops hard when you unlock it. That’s a failed balance, and on Andersen 400 Series, the cause is usually a broken spring inside the balance tube or a worn shoe. It’s dangerous because it slams fingers and chips glass, but it’s also one of the fastest repairs we do.
• The window won’t stay up without propping it. Same failure family, different stage. The balance spring has lost tension. You’ll notice it gets worse in winter when the house shifts slightly. Eventually you’re using a book or a stick to hold the window open, and that’s when you should call us.
• The lower corners of the frame feel soft to the touch. That’s wood rot, and in Wellington it’s almost always water intrusion from a failed exterior seal or an improperly flashed installation. If you can press a fingernail into the frame corner and leave a mark, the rot is already established. The fix may be a sash replacement, or it may be a full frame swap.
• You see daylight or feel a draft around the sash, even when locked. Andersen weatherstripping wears out after roughly 10 to 15 years of Florida sun and humidity. The gap lets air-conditioned air out and humid air in, which drives up your cooling bill and makes the room feel sticky.
• The window is fogged between the panes. The seal failed. You can’t clean it. On Andersen, a failed seal usually means replacing the sash glass unit or the whole sash, not the entire window. We quote it both ways so you know what you’re paying for.

Replacement Cost & What’s Included

In Wellington, Andersen window installation pricing breaks down like this:

• Standard sash replacement (glass and frame sash only): $75-$110 per window, depending on sash size and glass package.
• Full window replacement with Andersen 100 or 200 Series unit: $120-$160 per window for typical sizes, more for oversized or specialty shapes.
• Rotted frame repair before installation: $40-$90 per window, depending on how much wood we cut out and rebuild.

Parts are line-itemed separately from labor, so you see exactly what you’re buying. We don’t roll labor and parts into one number that hides what we make. If your Andersen unit is still under warranty, we handle the paperwork and the labor, and you pay only for what the manufacturer doesn’t cover. If it’s out of warranty, we show you OEM versus aftermarket side by side on paper.

Every install carries our Done Right Promise. If something’s not right, we fix it. No paperwork fight. The Keystone Standard means both manufacturer warranty layers are registered in writing before the truck leaves your driveway, with durations stated.

DIY or Call Us?

There’s no high-tension danger in a residential Andersen window swap, but there is real risk in getting it wrong. If you replace a sash without addressing why the old one failed, you’re buying the same problem twice. And if you set a window out of square, you’ll fight it every time you open it, seals will wear unevenly, and you’ll be calling us in two years anyway.

What you can do safely: check for soft wood at the corners, read the etching to confirm your series, and measure the visible glass. What you should not do: remove a full frame from a Wellington home without checking the flashing job underneath, or shim a window yourself if the rough opening is rotted. Rotted rough openings are common here. They’re also the difference between a window that works for ten years and one that binds in July.

If you’re unsure, call (561) 349-4826. We’ll tell you over the phone whether it sounds like a sash swap or a full install, and the estimate is free either way.
