A window well is a rectangular, semicircular, or elliptical shape that is a shield and sits inside a deep dug out of the ground around the basement window.

Why Do We Need a Contractor to Install Egress Window?

Installing egress windows in the masonry wall in the basement is more difficult and more expensive.

To locate the window, the basement has to be dug out of the wall and a deep window well has to be made which can provide full access to the window.

The foundation wall needs to be cut to create a rough opening of a size suitable for window installation.

Cutting masonry walls requires special tools, and this work is difficult as well as messy.

Determining the size of the opening in the foundation wall is also not easy as it needs to include wooden framing members such as pressure-treated studs, seals, and headers.

These framing members work to give the foundation reinforcement as well as nailing surfaces for window installation.

The desired type of window well enclosure on the exterior of the foundation is the most important factor when installing a basement egress window.

A certain type of enclosure is required for appearance and to hold the soil around the window.

Due to these factors, most people prefer to have this type of work done by a contractor.

Factory-Made Window Well

Window enclosures can be made using concrete blocks or a pressure-treated landscape tie, but it is easiest to purchase and install a prefabricated window that is compatible with the exit window.

There are many different factory-made window wells available.

Some of these include code-required steps or ladders and clear plastic caps.

This is necessary because it prevents snow and rain from filling the well.

Prefabricated units are easy to install as they are made with wide flanges and are secured to the base wall with masonry fasteners.

Egress Basement Window Installation Procedure

Egress Window Installation Steps Are as Follows.

Step 1. Once the foundation has been opened, it is necessary to prepare a new opening for the rough framing required to install the window. Any gaps or uneven surfaces around the cut openings in the foundation should be filled.

Step 2. Before attaching the window framing lumber to the masonry with construction adhesive and masonry fasteners, make sure that the masonry start is smooth and square.

Step 3. Some additional mortar should be used to tilt the bottom of the masonry so that the water flows smoothly outwards. Care should be taken to ensure that the sides of the framed opening are plumb as well as the threshold and header level.

Step 4. If necessary, plastic shims should be inserted between the framing and masonry to properly complete the rough opening. The joints between wood and masonry should be well-cooled to prevent water intrusion.

Step 5. The window can then be installed by attaching the nailing flanges to the outside of the framed opening. Hot-dipped galvanized nails or corrosion-resistant screws must be used. Exterior trim can be installed using a synthetic trim board after the window is fastened in place.

Step 6. To finish the exterior of the work, spread a little clean gravel on the floor of the window and backfill around the outside of the well enclosure.

Step 7. If the cover for the window is not well purchased then it is necessary to make the right cover and fit it in the right place as the cover helps to prevent children from falling into the well and keeping the inside dry during wet weather.
