Our Installation Process

We guide you through the installation process and provide information before installation day arrives, so you know what to expect. Our installers will work diligently and respectfully while installing new windows or doors in your home.


Project Manager Walk-Through

Your project manager will conduct an initial walk-through on installation day and can introduce you to your Marvin Replacement installers.


Removal Of Old Windows Or Doors

Our installers will carefully remove your old windows and doors before preparing the opening for new windows and doors.



Your installers will expertly place your windows and doors—true and plumb—to ensure a tight fit. They’ll use flashing and caulk, which can take up to 72 hours to cure, to help defend your house against any air leaks or possible water infiltration.


Final Walk-Through

Once we’ve completed your window or door installation, your project manager will conduct a final walk-through to make sure everything is to your satisfaction. We’ll also explain how to properly operate your new windows or doors and answer any other questions you may have about your new windows and doors.

Marvin Replacement Installers

We take extra steps to ensure that your window or door project gets handled by experts. Plus, we back up our work with a five-year installation warranty.
