Eifs Installers FAQs, answered by experts

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old windows.

The cost to install a bow window can range from $1,500 to $15,000, with a national average of $3,900. The total price includes materials, which can cost between $1,200 and over $14,000, and labor, which typically adds $300 to $1,900. Several factors influence the final cost, including the window's size and frame material. For example, vinyl frames are the most budget-friendly option, while wood frames are more expensive. Custom features or energy-efficient upgrades will also increase the price. For comparison, a bay window installation typically costs between $1,000 and $7,000.

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

Most professionals can install a window well in two to three days, depending on the size of the well and the window you want inside it. If you’re just replacing an existing window well, the work is much less intensive, and most experts can get the job done in just one day. Connecting the window well to a drainage system or installing a custom concrete window well will naturally take longer, but even the most complicated installations shouldn’t take more than three days.
