What to Know About Installing Replacement Windows

A window is only as good as its installation. Prioritize proper installation by learning about the installation options, types and process.

A great replacement window goes a long way. It can help save you money on your energy bill and revive the look of your home — both inside and out. But all too often, homeowners overlook the importance of proper installation when purchasing replacement windows. To get the best long-term performance from your windows, it’s crucial that they be installed correctly.

In this article, we’ll discuss two options for installers, two installation types and the overall installation day process.

Options for Window Installers

Finding the right replacement window installer to tackle your project is just as important as finding the right window itself. Below we’ll discuss four main options for replacement window installers:

Visit Your Local Home Improvement Store

If you live near a Lowe’s home improvement store, stop in and talk with project specialists who are ready, knowledgeable and equipped to help you specifically with Pella windows. You’ll be able to schedule a free consultation with a Lowe’s team member and get a project quote that includes installation.

Depending on where you live, you might not have a Lowe’s store near you, but maybe you have a close relationship with your local home improvement store. Perhaps you’ve known the franchise owner for a long time or enjoyed working with them on past home improvement projects. Chances are, the home improvement store nearest you partners with subcontractors to help provide customers with replacement window installation services.

When considering this option, take the time to vet the contractor or subcontractor affiliated with your home improvement store of choice. Ask them how long they’ve been operating and how much business they receive from referrals. Referrals are a strong indicator that the contractor’s work is satisfactory. Also, consider asking the home improvement store if they provide any warranty options for coverage after installation day.

DIY Window Installation

We respect the do-it-yourself drive of a homeowner who wants to handle the job on their own, so much so that we provide how-to guides with instructions for replacement installation. If you're debating between hiring a pro and installing yourself, understand that replacing windows can be an undertaking. Make sure you’ve researched all the steps and purchased all the necessary window installation tools and materials. Only get started if you’re confident you can handle the job on your own.

Types of Window Replacement Installation

Now that you understand the options for window installers, let's talk about replacement types. There are two main types of window replacement installations: pocket replacement and full frame replacement. Read about each method below to determine which is right for your project.

Pocket Window Replacement

This method replaces the window while leaving the existing frame in place. Sometimes referred to as a retrofit or insert window installation, this process can be completed relatively quickly — it usually takes about an hour per window. With pocket replacement, your new window selection is limited by the size of the existing opening.

Full-Frame Window Replacement

This method is considered a total replacement as the existing window frame and sash are removed. It’s necessary when the existing frame is damaged or not in great shape, or when the new window will not fit the size or shape of the existing opening. The replacement window is installed in a new frame with new insulation as well as trim. Requiring more materials, time and labor, full-frame replacement usually costs more than pocket replacement. There is work to be done both inside and outside the home, but because the opening can be changed to accommodate an entirely new style of window, this method provides greater design flexibility.

How much does window installation cost?

There are numerous aspects that affect the cost of window installation. Here are just a few primary factors to consider:

• Region:Installation cost varies in different markets, depending on demand and the number of skilled installers in your area.
• Number of windows: The more windows, the more time, material, labor and cost required from installers.
• Size of windows:Larger windows are typically more time- and labor-intensive to install.
• Type of windows: Specialty windows and bay and bow windows usually cost more to install.
• Location of window: Windows on the ground floor of a home are easier to replace than basement and upstairs windows.
• Age of home: Older homes sometimes have non-standard window sizes or structural problems that require more time and attention to ensure proper installation.
• Exterior of home: It’s usually easier to perform a full-frame replacement in a home with pliable siding than one with solid brick or stucco.

Window Installation Process

How to Prepare for Installation Day

Taking these small steps will ensure that the window replacement process goes as smoothly as possible. Move furniture and decorations away from the window to be replaced, leaving a little extra space. Most important is the safety of your family. Keep pets or children in a safe place away from your work area while your windows are being replaced.

What to Expect on Installation Day

To ensure that your home and belongings are protected during the installation process, the crew will lay down drop cloths in any work area. The drop cloth will trap debris and dust, protecting your home from installation day residue.

Next, your old windows will be carefully removed and disposed of. After removing your old windows, the installation process for your replacement windows will begin. Depending on the type of installation you have (pocket or full frame replacement), the installation can be quite laborious and time consuming, so keep this in mind on installation day.

As the crew nears completion of the replacement window installation, the windows will be finished with your choice of interior or exterior trim and any necessary hardware.

After completing the job to your satisfaction, it will be thoroughly cleaned up. Your old windows will be hauled to your car, and you will be shown the completed project and taught how to operate and care for your new windows!

Finally, there is only one thing left to do after the installation is complete. Sit down. Relax.
