How To Avoid Water Leak Problems When Replacing A Home Window

Replacing a home window can be difficult. One of the most common issues homeowners face when installing a new window is water leakage when the window is not replaced correctly. Fortunately, there are some steps that a window replacement contractor follows to avoid water leaks.

The Right Window for Your Climate

Different types of windows have different resistance levels to water infiltration, depending on their design, materials, and installation methods. For example, vinyl windows are more water-resistant than wood windows, and casement windows are more resistant than sliding windows.

They will also consider the window's direction and the amount of exposure to rain, snow, and wind it receives. For example, you might live in a rainy or humid area. In that case, you may opt for a window with a higher performance rating for water resistance.

Measuring the Opening Carefully 

Before removing the old window, the contractor will measure the opening accurately and ensure it is square and level. They will also inspect the condition of the wall around the opening and repair any cracks, holes, or rot they find.

They may need shims, flashing tape, or caulk to seal any gaps or irregularities in the opening. They will also make sure that the opening has a proper slope or sill pan at the bottom to direct any water away from the wall.

Following the Manufacturer's Instructions

Every window comes with specific instructions for installation that the contractor will follow closely. These instructions will tell the contractor how to position, secure, and seal the window in the opening. They will use appropriate tools and materials to avoid cutting corners or skipping steps. They will also check the alignment and operation of the window before they finish the installation.

Using Insulation and Weatherstripping

After they install the window, they will fill any gaps between the window frame and the wall with insulation material, such as foam or fiberglass. This will help prevent heat loss and air leakage around the window. They will also apply weatherstripping around the edges of the window sash to create a tight seal against water and air infiltration. 

Maintaining the Window

Even after installing your window correctly, you should check it periodically for signs of water leakage or damage. You should look for cracks, peeling paint, discoloration, mold growth, or condensation around the window. If you notice any problems with your window, you should fix them immediately.
