A replacement window is a new window made to fit an existing opening, installed in place of one that has worn out or stopped sealing. Ours are custom-measured and professionally installed, and they cut cooling costs, quiet the road outside and make the whole house look newer. We carry the full Andersen line, and American Eagle Builders is a certified Andersen contractor for windows and doors.
A replacement window is a new window made to fit an existing opening, so the old unit comes out and the wall around it mostly stays as it is. It is the usual choice when a window has fogged, drafts, sticks or no longer locks well, and the frame around it is still sound.
In North Texas the choice turns mostly on sun and movement. West and south walls take the most heat, so the glass rating on those walls matters more than on a shaded side. Houses on clay can shift a little with the seasons, which is why each opening gets measured on its own rather than copied from the one beside it. American Eagle Builders installs four Andersen lines, and the right one depends on the look you want, the frame material and how the opening is shaped. If only one part of a window has failed, a repair may be the better answer, and we will say so.
Four Andersen series, one install crew. We’ll walk you through the trade-offs in person and price the one that actually fits your house and your budget.
Best Value
A composite-frame window that gives you modern performance without the premium price tag. A strong starting point when you’re replacing every window in the house at once.
Most Popular
Andersen 400 Series windows: a warm wood interior paired with protective exterior cladding, so the look is traditional inside with almost nothing to maintain outside. The line most of our customers land on.
Architectural
Andersen A-Series windows, for when the window needs to match a specific architectural style. The most configurable option we offer, with shapes, sizes, grille patterns and finishes worked out to suit the house.
Fully Custom
Andersen E-Series windows: the top of the range and effectively made to order. For an unusual opening, a specific color to match or a large feature window, this is the series that can do it.
The 100 Series (fibrex composite) is a fit for getting the most window for the budget. The 400 Series (wood interior, vinyl-clad exterior) is a fit for the traditional look most homeowners want. The A-Series (wood interior, fiberglass-clad exterior) is a fit for matching a specific architectural style with correct proportions and hardware. The E-Series (wood interior, aluminum-clad exterior) is a fit for large openings, arches and custom shapes. The table has the detail.
| Series | Frame material | Best for | Color range |
|---|---|---|---|
| 100 Series | Fibrex composite | Getting the most window for the budget; holds shape in Texas heat better than vinyl | 9 exterior colors |
| 400 Series | Wood interior, vinyl-clad exterior | The traditional look most homeowners want; paintable or stainable inside | Limited exterior palette |
| A-Series | Wood interior, fiberglass-clad exterior | Matching a specific architectural style with correct proportions and hardware | 11 exterior colors |
| E-Series | Wood interior, aluminum-clad exterior | Large openings, arches and custom shapes; color matched to an existing window | Effectively unlimited |
Every opening is measured individually, because a house rarely has two identical ones. You see the series options side by side and get a firm written estimate.
Andersen builds the units to those measurements, so the installers are not shimming a stock size into a hole it does not fit.
Our own crews set, flash and seal each unit, then trim inside and out.
We check operation and locks on every window with you, clean up, and hand over the manufacturer warranty alongside ours on the installation.
Fibrex is Andersen’s composite: reclaimed wood fiber bound in polymer. It holds its shape in Texas heat better than vinyl, which softens and can bow on a wide west-facing opening, and it lets the frame be narrower for the same strength, so you get more glass and less frame.
A replacement window is made to fit the existing frame opening, so the siding, trim and inside walls stay as they are. A new construction window has a nailing flange and goes in with the frame opened down to the studs, which means siding and trim work around every window. Replacement is the usual choice when the frames are sound. Rotted or out-of-square frames are the reason to open the wall, and we check that at the estimate.
On average our installation teams complete window installations within 2 to 4 days once your windows arrive. Custom-built windows take time to manufacture after measuring.
Customers regularly report noticeably lower summer cooling costs and a quieter house. Savings depend on what you’re replacing. Single-pane aluminum windows show the biggest change.
Yes. Where your city requires one, we file it and deal with the inspection.
Homeowners replacing most or all of their windows who want a durable, no-paint frame at a sensible price, and who are happy with a finished interior instead of stainable wood. Rental and resale homes are a common fit too.
