    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.

Frequently Asked Questions

FAQs about My Product

Do casement windows have screens?

Yes, casement windows can be ordered with screens on the inside where they're protected from the elements.

Where is a casement window used?

Because casement windows are easy to operate with one hand, they are commonly used in hard-to-reach areas like over a kitchen sink or bathtub. Casement windows are also popular in bedrooms, living rooms and home offices.

What is the difference between casement and awning windows?

The difference between casement and awning windows is the placement of the hinged side. Casement windows are hinged at either the left or right side. Awning windows are hinged at the top. Both casement and awning windows swing outward to open and close with a crank that folds away when not in use.

What are the benefits of replacing my windows?

Energy efficiency, reduced noise and curb appeal are among the key benefits of replacement windows.

FAQs about Purchasing Online

For online orders, what is your policy for returns and products damaged during shipping?

We’re committed to customer satisfaction. If the product you ordered online is damaged during shipping or you do not receive exactly what you ordered, we want to make it right by refunding you in full or sending you a new product. We do not accept returns of undamaged made-to-order products in which a buyer ordered the incorrect size or color, or decided the product was no longer needed. See pella.com/warranty for additional details and exclusions. If you have questions about returns and refunds, please email shop@pella.com.

Who should buy online?

Buying online is great for the confident do-it-yourselfers. You’ll take charge of the project by measuring, selecting and installing products on your own. Shopping online is quick, convenient and easy – especially when you only need to replace a few standard windows. For more complex orders, it makes more sense to work with a local Pella Representative who can assist throughout the process.

What’s included in my online window and door purchase?

Product only. When you purchase a window, door or replacement part online, your order will arrive with the product only. Installation is not included. If you need installation parts and accessories, those can be purchased online as well.

Who will install the products I ordered?

When you receive your order, you can either install the product on your own with help from our installation kit. Or, hire a Pella Certified Contractor® to take care of installation for you. They are trained and certified to install Pella products.

How long will it take to receive my online order?

For online orders, a local Pella team member will call within 2-14 weeks to schedule pick up or delivery depending on delivery method and production timing. The time to receive your order varies since all products are made to order based on your specifics.
