    Why Choose Pella
    We opted to purchase our Pella door directly from Pella (vs. from a big box home supply store) because of the expertise of its installers (per the salesperson) and Pella's guarantee of its products.
    Memorable Aspects
    We were surprised that we had to wait so long for the installation of the door (door ordered in Nov. but not installed until early Feb.). We also financed the door through GreenSky and did not expect that payments would be due to them upon order vs. upon installation.

    Why Choose Pella
    The employee discount and the ease of Pella handling everything from start to finish.
    Memorable Aspects
    The instalation crew was second to none. There is nothing negative that can be said about them.
