If you're wondering whether new windows will increase your home's value, the answer is yes, but not necessarily in the way you might think. Will they instantly add tens of thousands to your resale price? No. But will they make your home more appealing to buyers, improve energy efficiency, and enhance curb appeal? Absolutely.

Outdated, drafty windows are a red flag. Buyers don't want to deal with rising energy bills or the hassle of replacing them right after moving in. Fresh, modern windows make your home look well-maintained, feel more comfortable, and stand out in the market. So, are new windows worth it? If your current windows are aging, inefficient, or ugly, upgrading them is one of the most innovative home improvements you can make.

Cost vs. Value: How Much Can You Recoup?  

Investing in new windows isn't just about aesthetics. It's about improving comfort, energy efficiency, and resale value. But before committing to a complete replacement, understand the numbers first. How much will it cost? Can I purchase Milgard windows and install myself or will I need an installation company? What's the return on your investment? And does it make sense based on how long you plan to stay in your home? Let's break it down.

Cost Of Installation  

Window replacement costs vary widely depending on material, size, and labor. On average, homeowners spend $850 per window, with prices ranging from $300 for product only up to or beyond $1,200 per unit. Let's say your home has around 22 windows; the total bill could be anywhere from a few thousand dollars up to tens of thousands of dollars depending on whether you are installing yourself vs higher an installer.

Currently the average cost of product and installation for whole house retrofit windows in San Diego is around $10,000. Of course, your home may be smaller or larger than the typical home, or the requested window materials, difficulty of install, damage to the existing rough openings requiring new installation rather than retrofit, or specialty window requests creates a wide range of possible prices.

Material choice plays a significant role in pricing. Vinyl windows are the most affordable, while fiberglass and wood are on the higher end due to durability and aesthetic appeal. Additional costs, like permit fees or structural modifications, can also increase the final price.

Expected Recoup Values  

While new windows won't return every dollar spent, they still offer a strong return on investment (ROI) compared to many other home improvements. According to the 2024 Cost vs. Value Report, the average recoup value for:

  • Vinyl windows are 67.1%.
  • Wood windows are 62.9%.

Due to durability, fiberglass will likely yield even higher returns. In some cases, upgraded windows help homes sell faster by attracting buyers who want a move-in-ready property without the hassle of replacing outdated or inefficient glass.

Why Do New Windows Increase Property Value?  

New windows add value in more ways than one. They boost curb appeal, improve energy efficiency, and secure your home. Buyers notice these details. Plus, when your home stands out with high-quality windows, it sells faster and often for a better price. First impressions matter so gain the benefit of improved curb appeal. If a buyer pulls up to a home with faded, chipped, or outdated windows, they'll assume the rest of the house is in similar shape. Even if the interior is pristine, old windows can drag down a home's perceived value.

New windows also make a home look well-maintained, clean, and modern. Larger window designs also enhance natural light, creating a bright, inviting space inside. These small details can make buyers more willing to pay your price. When buyers see fresh, energy-efficient windows with years of life left, they won't worry about costly replacements anytime soon. That long-term value is a significant selling point. Newer windows also mean fewer maintenance issues. Old windows can develop leaks, condensation between panes, or warping, leading to drafts. With high-quality Milgard replacements, those concerns disappear, giving buyers more confidence in the home's overall condition.

Old windows are also a security risk. Worn-out frames, loose locks, and single-pane glass make break-ins easier. Newer windows often feature reinforced locks, double or triple-pane glass, and impact-resistant materials, offering increased security and reduced noise. Buyers looking for a quiet, safe home will pay more for these added benefits.

Upgrading the energy efficiency of your windows could have big returns. According to the U.S. Department of Energy, windows are responsible for up to 30% of a home's heat loss. That means outdated windows can cost homeowners hundreds each year in wasted energy. Upgrading to energy-efficient windows can cut heating and cooling costs by as much as 13%. For a buyer, that means immediate savings on utility bills. And for sellers, it's an easy way to make your home more attractive in a competitive market.  

Newer windows don't just look better and provide better security and energy efficiency; they operate better, too.

  • Easier maintenance: Many modern windows feature tilt-in designs for quick and easy cleaning. No more struggling to clean the exterior glass from the outside.
  • Better ventilation: Older windows can get stuck or warped over time, making them difficult to open. New windows slide, crank, or tilt effortlessly, allowing for better airflow and ventilation.
  • UV protection: Many replacement windows now include low-E glass coatings, which block harmful UV rays. This coating helps protect flooring, furniture, and décor from fading while improving energy efficiency.

These features aren't just nice to have as they make everyday life easier, adding personal value for homeowners and resale appeal for buyers.

Should You Replace Your Windows Before Selling?

If your windows are old, damaged, or downright drafty, replacing them before selling can be brilliant. But a complete replacement might be unnecessary if they're still in good shape. So, when is it worth the investment?

Not all aging windows need replacing before you list your home, but certain red flags can turn buyers away or drive down your asking price. If you notice any of the following, it might be time for an upgrade:

  • Windows are 15 years old or longer and showing signs of wear
  • Difficulty opening or closing due to warping or sticking
  • Drafts or sudden spikes in energy bills, resulting from failing insulation
  • Condensation between panes, signaling a broken seal
  • Visible damage, like cracked glass, peeling paint, or rotting frames
  • Excess outside noise, meaning your windows aren't insulating sound properly

Buyers don't want to walk into a home and immediately start thinking about repair costs. If they see outdated or failing windows, they might offer less or skip your home altogether in favor of one with modern upgrades.

If your windows are clearly past their prime, replacing them can increase your home's desirability, but if they're still in solid shape, a deep clean, minor repairs, and fresh trim paint might be all you need to keep buyers interested. Before making a decision, consult a professional. A window expert can assess whether replacement is needed or if minor improvements can make your home market-ready without the added cost.

Upgrade Your Windows For A Better Home And Higher Value   

If you're replacing your windows, quality matters in the materials you choose and the installation itself. Cheap, low-quality windows might save money upfront, but they won't last, insulate properly, and won't add much value to your home. Buyers notice the difference between high-performance, energy-efficient windows and flimsy, outdated ones. That's where Milgard's quality windows come in.

Even the best windows won't perform well if installers do the job incorrectly. Poor seals, gaps, and rushed work can lead to drafts, moisture issues, and higher energy bills. That's why working with trusted professionals who get it right is crucial. At US Window & Door, we install Milgard windows designed for durability, efficiency, and security.
