Eifs Installers FAQs, answered by experts

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

You install a window well 8 to 12 inches deeper than the base of the window sill. After filling the well with drainage rock, the well should sit 3 inches below the bottom of the window. The top of the window well should also be at least 3 inches higher than the surface-grade ground. The window well should be about 6 inches wider than the window opening.

DIY is possible for experienced individuals. Professional installation ensures compliance with building codes and proper sealing.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.
