Best Value Replacement Windows: How to Get the Most for Your Money in 2026

Renewal by Andersen's take

Interior designer, TV host, and Renewal by Andersen brand ambassador Breegan Jane always recommends window and door replacement to her clients to boost home value. "Replacing your windows and doors with durable, up-to-date product, new technology, Fibrex^® material durability—that adds value to your actual home. You want to feel good about the things that are going into your home.”

Here's something most homeowners love to hear: replacement windows can help pay for themselves over time by helping lower energy bills. And we're not talking about pennies—these savings can add up to real money, year after year.

According to ENERGY STAR^®, replacing your windows with ENERGY STAR certified windows lowers household energy bills by an average of 12%. Higher quality window frame material, glass options, weatherstripping, and other window components all contribute to the energy efficiency of an overall window unit.

How do new windows contribute to better energy efficiency in your home? Let's break it down:

• Double-or triple pane glass with argon gas blend insulation: Double-pane glass features two layers of glass with a gas blend sealed between them (usually argon), a better insulator than oxygen, minimizing heat transfer from outside to inside. Triple-pane glass has an extra pane of glass to keep more heat in and cold air out, making this the most energy-efficient glass, best suited for cold climates.
• Low-E coatings: Low-emissivity material applied to the glass helps keep heat inside your home during winter and blocks it from entering during summer—and also reduces harmful UV rays, which means less fading on your hardwood floors, furniture, and artwork. Different coatings work better for different climates. Read about the difference between glass options with replacement windows.
• Weatherstripping provides superior weather tightness, helping guard against drafts and water infiltration.
• Window frame material: Vinyl is commonly used by many other window replacement companies, but it doesn't always last as long as clad wood and composite options, with low-quality vinyl leading to cracks, pitting, and leaks. Clad wood frames are typically high quality and can last for a long time, but some need to be painted or stained regularly to prevent rot. Composite frame material, like Fibrex^® composite material, can last 30 years or more according to a recent study in a Minnesota home^{^^}—and doesn’t require maintenance like other materials.

In general, look for ENERGY STAR^® certified products, which meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency.

Renewal by Andersen and Berkeley Lab modeled the comfort in a typical living space within a typical home using our windows with Enhanced Triple-Pane glass, as well as typical clear air-filled dual-pane double-hung vinyl windows to -13.6°F sub-zero winter day in Minnesota, with the thermostat set for an indoor temperature of 72°F.

Renewal Andersen's take

Many homeowners notice the difference immediately after getting their windows replaced—fewer cold spots by the windows and more consistent, more comfortable temperatures throughout the home, no matter the season. And best of all? Our windows can help lower energy bills, making the investment pay off month after month.

If you've been waiting for the ''perfect time'' to replace your windows, the answer is a bit more complicated. But here are some factors to consider when planning out your window project:

• Promotions make it more affordable. Check for seasonal sales and promotions. If you don’t have all the money for a project now, some companies offer financing options with no money down and no interest for several months. Sometimes winter installation comes with better promotions. Read more about the cost of replacement window.

• Energy efficiency savings can start immediately, so every month you wait to replace can mean another month of higher energy costs.

• Professional installation works year-round. You might be thinking, "But what about winter? Won't my house be freezing during installation?" This is something to consider and ask companies when you’re in the job bidding phase. Some companies, like Renewal by Andersen, typically install one window at a time, minimizing outdoor exposure to your home.

What Do Homeowners Say?

As Ross Trethewey, Building Engineer on Ask This Old House, puts it: "You can have the best window in the world. And if it's not installed right, you're not going to have a great outcome."

According to ENERGY STAR^®, "Even the best windows, doors, and skylights can be drafty if they are poorly installed.'' They recommend seeking out professionals certified to install the specific ENERGY STAR^® certified replacement windows and doors you have selected for your home.

Professional installation can be part of the value of window replacement—it ensures long-term performance, energy savings, and helps maintain peace of mind. Renewal by Andersen uses Certified Master Installers, who complete rigorous training in the best practices in window replacement.

Renewal by Andersen's take

Take it from Liz Rishel, a DIY pro and Renewal by Andersen brand ambassador. When she bought her beach cottage in Florida, she noticed water damage on a few of the windowsills. She later discovered the previous homeowner improperly installed windows themselves, leading to water leakage inside the home. “Even though I’m a DIYer, there are some projects you just shouldn’t DIY, and windows and doors are definitely two things on that list. I’m going to trust the pros on those projects,” Rishel says.

Laura, a homeowner from Arizona and Renewal by Andersen customer, said, “I have never purchased windows before and there were cheaper options, but I didn't want to worry about anything. I knew I wanted the full service that Renewal by Andersen promised to deliver. Everything progressed like a well-oiled machine and I am truly grateful.”†
