Recently, we noticed a major national window brand claiming that a full window replacement can boost your home’s market value by a whopping 15%. On paper, that sounds like a slam-dunk upgrade. But when we tried to track down independent verification, all we found were internal surveys and anecdotal realtor quotes. Nothing you could point to and say, “Here’s the proof.”
So, we decided to do our own homework. We pulled in data from Remodeling Magazine’s Cost vs. Value reports and recent Journal of Light Construction figures to give San Antonio homeowners the unvarnished truth: what window ROI really looks like, and how we try to set realistic expectations.
Here’s what you need to know before you decide whether to replace your windows for resale value or just for a more comfortable home.
Myth vs. Reality: The “15% Value Spike”
The Claim: “New windows increase your home’s value by at least 15%!”
The Source: An internal 2022 “Realtor survey” cited by the manufacturer, we couldn’t find any public data to verify. Source
The Reality: Independent studies show you recoup roughly 60-70% of your window investment when you sell, even that upper range includes energy-saving benefits, not just resale value.

What the Experts Actually Say
- Remodeling Magazine’s Cost vs. Value (2024 edition): Homeowners recover about 60-70% of their window replacement cost at resale.
- Money, NerdWallet & This Old House: Agree on 60-70% ROI, plus softer wins like curb appeal and energy savings.
- Angi / Realtor.com: Sometimes cite up to 85% ROI, but again that’s percentage of your project cost, NOT of your total home value.
Quick Math Example (2024 JLC Data)
Window Type | Project Cost | Resale Value Recouped (≈ 60–70%) | Net Added Value at Sale |
Vinyl Replacement | $21,000 | $14,000 (≈ 67%) | + $14,000 |
Wood Replacement | $25,799 | $16,222 (≈ 63%) | + $16,222 |
Pro Tip: Even when you recoup 70% of your investment, that still means you’re out of pocket for the remaining 30-40% but you get to enjoy upgraded windows in the meantime.
Why We Call Out Misleading Ads
Some companies slap huge percentages on their ads because sensational claims sell. But when homeowners call them out? Crickets.
At Southwest Exteriors, we’ve got a zero-tolerance policy for misleading marketing. We’d rather earn your trust with facts:
- We never promise a “15% bump” on your entire home value
- We share independent ROI data, we don’t create or cherry pick “surveys” that you can’t verify to try and produce value in our products.
- We educate you on both tangible returns (resale recoup) and intangible perks (energy savings, comfort, curb appeal)
Beyond Resale Value: The Hidden Wins of New Windows
Even if you only recover 60-70% of your cost at sale, there are plenty of reasons to upgrade:
- Energy Savings: A quality, modern window package can lower your heating and cooling costs, but quoting a specific savings percentage without analyzing your home’s unique factors would be misleading.
- Comfort & Health: Better insulation means fewer drafts, less condensation, and no mold risk
- Curb Appeal: Fresh windows instantly elevate your home’s look
- Warranty Peace of Mind: Quality manufacturers back their products with robust warranties, ours even covers labor for as long as you own the home

Frequently Asked Questions (FAQ)
Q: Will new windows really boost my home’s value by 15%?
A: No, there’s no independent data supporting a 15% increase on your entire home value. That number stems from an internal realtor survey and isn’t verified by public studies.
Q: What ROI can I realistically expect on replacement windows?
A: Most reputable sources (Remodeling Magazine, Journal of Light Construction) report homeowners recoup about 60–70% of their window investment when selling, plus ongoing energy‐savings benefits.
Q: How is window ROI calculated?
A: ROI = (Resale Value Increase ÷ Project Cost) × 100%.
For example, a $20,000 window project that adds $13,000 to resale value yields a 65% ROI.
Q: Which factors have the biggest impact on my window ROI?
A:
- Frame material & glass quality: Premium options (fiberglass, wood-clad, Cardinal IGUs) retain value longer.
- Installation quality: Proper flashing, sealing, and workmanship prevent future repair costs.
- Local market conditions: Neighborhood trends and timing can swing your actual recoup rate.
Q: Beyond resale value, what other benefits do new windows deliver?
A:
- Energy savings: Lower heating/cooling bills (varies by home).
- Comfort & health: Fewer drafts, less condensation, reduced mold risk.
- Curb appeal: Fresh, modern windows boost your home’s look and marketability.
Q: Does window material choice (vinyl vs. fiberglass vs. wood) affect ROI?
A: Yes. While higher-end materials cost more up front, their superior performance, durability, and longer warranties can improve long-term satisfaction and resale appeal, often making fiberglass a smart upgrade if you’re choosing a dark color.
Q: How can I finance or budget for new windows?
A: Southwest Exteriors offers flexible payment plans tailored for San Antonio homeowners, including 0% interest options and local incentives, so you can spread your investment over time without surprises.
