I want to update the color of my door. What type of paint should I use?

If you’re purchasing a new entry door, we recommend having it finished with our PrismaGuard finishing system, which is available through our dealers. However, if you plan to paint your door yourself, we recommend using an acrylic, water-based, exterior paint.

How long does it take to install a new entry door?

While installing a door may seem like something that can be done quickly and easily, it can take a bit more time to be completed correctly. Removing the existing door and prepping the various system pieces, as well as the opening, adds time to the overall installation process. In addition, door installation requires tools that you may or may not have and usually requires more than one person.
