Frequently Asked Questions about our Window Replacement Process

From one-company accountability and industry-leading limited warranty to our exceptional people and impressive technology, we’ve answered our customer’s top questions about our superior process.

I’m researching replacement windows and considering Renewal by Andersen. What’s the first step I need to take?

First, you’ll schedule your free design consultation. Give us a call or fill out our form on our website, and we’ll set up a specific time that works for you (no vague appointment windows). During your individual design consultation, we’ll get to know you and your home, identify its particular challenges or issues, and then talk about ways we can address them. At the end of your consultation, you’ll be left with a printed (or electronic), detailed estimate with pricing good for one year.

Why is the individual design consultation so important?

There’s no home exactly like yours, so you shouldn’t expect a one-size-fits-all solution when it comes to your windows. All of our windows are custom crafted and made-to-order to fit your home’s exact needs. Therefore, before our trained design consultants can give you an estimate, they need to learn about your situation. Your consultant will meet with you in the comfort of your home, at a time that fits your schedule. He/she will walk through the details of your particular situation, listen to your needs, talk with you about a number of options, and provide you with pricing for your specific project that will allow you to review your options and make the best decision for your home and your budget. Because your home is unique, it shouldn’t be treated like any other house on the block—that’s why your design consultation is so important.

What happens during the free consultation?

Some of our homeowners know exactly what they want when our consultants walk in the door—they know the number of windows, what style, what colors, even which hardware. But for many homeowners, this is uncharted territory. When you schedule your free in-home design consultation, here’s what will happen:

  1. First, we’ll listen to you about your goals and the vision you have for your new windows.
  2. We’ll inspect your home’s current window situation and identify any unique design and installation challenges.
  3. We’ll talk with you about ways to balance beauty and budget, and come up with a design solution(s) that fits your home, your timeline, and your bottom line.
  4. He/she will answer any and all questions you have—whether they are about style (“Can you do a dark exterior trim to match my siding?” or “What’s the right look for an Arts and Crafts bungalow?”), logistics (“It’s fall…do I have to wait until spring?”), or function (“What do you recommend for an elderly woman who has mobility issues?”).
  5. Your design consultant will look for the best possible deal for you—letting you know of any current specials or offers running, configuring bulk or quantity discounts, and walking you through all of our flexible payment options.
  6. Your consultant will draw up an electronic contract through our iPad® app and have it ready for you along with a detailed estimate and pricing good for one year.

I’m having a hard time imagining all of the window styles, grilles, colors, and hardware options. How can you help?

Your design consultant will be bringing actual product samples as well as color swatches so you can see, touch, and feel everything first-hand. What’s more, our 3D iPad® app can help you actually visualize OUR windows on YOUR home—from both the inside and the outside. You can experiment with colors, window styles, grilles, trim sizes, hardware options, interior stain colors, and more!

Where are my windows built? Who builds them?

After you decide you move forward with Renewal by Andersen, your project specs are sent to our newly expanded state-of-the-art manufacturing facility in Cottage Grove, MN—only a few miles down the river from where Andersen Corporation came to life over 100 years ago.  Your windows are custom crafted and made-to-order with precision and care by our dedicated employees who take great pride in their work.

One thing that makes production special to us is that we only make to order. Every unit that we make has an order and a name attached to it. When an order comes down the line, our plant workers take care of your project because we know that this is YOUR window, not just an anonymous order.

What makes your installers the best in the business?

Installation of a replacement window isn’t simply a matter of putting a standard-size window into a hole in the wall. It’s a matter of expertly fitting YOUR custom window into YOUR home. Replacement window installers need to be prepared to handle any number of challenges such as variations in wall materials and thickness, various types of casings or sill constructions, changes from house settling, and even unforeseen structural damage. This is why we only hire the best installers—folks who are professional craftspeople experienced in installing windows in homes of all shapes, sizes, and styles. Our installers are proud of the work they do and the products they install, and they’re dedicated to working with individual homeowners and going the extra mile whenever necessary (and often even when it’s not). Here’s what you can expect to happen on installation day.

What is a Certified Master Installer?

Our Certified Master Installer program takes “professional” to the next level with meticulous training, extensive supervision, and high expectations. Prior to certification, we require all trainers and installers to demonstrate their knowledge of construction materials, building codes, and installation methods. Learn more about what it means to be a Certified Master Installer.

What happens if I need service on my Renewal by Andersen® replacement windows?

Our windows come with our toll-free number and a unique ID number on each one. Should you have any issues, give us a call and our in-house Customer Care Representatives will be able to identify your exact window (using that unique ID number) and help you get your concerns remedied.

What does the limited warranty cover?

When we say we’re with you from start to finish and beyond, we mean it. Our industry-leading limited warranty covers the glass, the frame and hardware, AND the installation. It’s a warranty that is made as a promise to you, and backed by extensive testing.

What happens to my warranty if I sell my home?

Don’t worry—the limited warranty on your Renewal by Andersen® products is fully transferable, should you sell your home.

How many people will I be in contact with throughout the process?
