New & Custom

When installing windows, Ratti Builders typically use new custom windows instead of cheaply made replacements.


If we’re handling both the siding and window installation, we can greatly improve your home’s insulation by using 1″ Dow R-5 rating foam.

Replacing windows and using our insulation will also qualify you for tax credits from the federal government.        


A flexible, waterproof material known as flashing is installed around the perimeter of the opening to prevent moisture from entering the building.

Window placement

The new window is placed in the opening and temporarily secured in place.


Caulk is applied around the perimeter of the window to ensure a tight seal and prevent air leaks.


If necessary, trim is installed around the perimeter of the window to cover the gap between the window and the wall.

Final inspection

The installers at Ratti Builders will inspect the window to make sure it is installed correctly, operates smoothly, and is properly sealed.

The specific steps and materials used for a home window installation can vary based on the type of window, the age and construction of the building, and local building codes.

It’s important to use a professional and experienced window installer from Ratti Builders to ensure that the installation is performed properly and meets all necessary safety and building standards.
