Most renovation data disagrees with itself. The two big remodeling-value reports, one built on resale estimates from real estate professionals and the other on a REALTOR® survey, use different cost sources, survey different people, and routinely land on different numbers for the same project. That is normal, and it is one reason to be careful with any single figure.
So when both reports put the same project at or near the top, pay attention. In 2025, that project is a new front door.
What the three datasets say
A midrange steel entry door replacement costs $2,435 nationally and adds an estimated $5,270 at resale, 216.4% of the cost recouped and second of 28 projects, according to the Remodeling 2025 Cost vs. Value Report (www.costvsvalue.com), which asks real estate professionals in 119 U.S. markets to estimate resale value, with job costs from Verisk XactRemodel.
NAR and NARI's 2025 Remodeling Impact Report, which asks 4,005 REALTORS® about value recovered and NARI members about cost, puts a new steel front door at 100% of cost recovered, the highest recovery of any project in that report.
Zillow's 2022 front-door color study asked recent and prospective buyers to make offers on the same home shown with eleven different door colors. A black door drew offers $6,449 higher than the baseline; slate blue drew $1,537 more and olive green $969 more; pale pink drew $6,516 less, and cement gray scored lowest. Zillow's dollar figures were calculated against the typical U.S. home value at the time, $334,141.
Two of these estimate resale value. The third measures what buyers say they would offer for the same house with one variable changed. None of them is a guarantee, since every one is an estimate or a survey, but they point the same way, and they are the best evidence available on the cheapest project in the ranking.
Why a door does so much
A front door is a small object with an outsized share of the first impression. Three things stack up in its favor:
It is the cheapest line in the top ten. At $2,435 nationally, the steel door costs about half of the #1 project (the $4,672 garage door) and a fifth of the #3 project (stone veneer, $11,702). It is the only top-ten project most homeowners could fund from a single month's savings.
It is where the buyer stands. Every showing, every inspection, every appraisal begins at the front door, at arm's length, for the length of time it takes to work a lockbox. No other surface of the house gets that kind of scrutiny from that distance.
It photographs. Johnson, Tidwell and Villupuram (2020), in the Journal of Real Estate Finance and Economics, scored curb appeal from Google Street View images with a deep-learning classifier and found a property's own curb appeal accounted for up to 7% of sale price when combined with its neighbors', with the premium larger in weak markets. The door is the center of that image.
Steel, fiberglass, or the big one
The Cost vs. Value Report prices two door projects and they are not the same project. The midrange steel entry door is the $2,435 project above, returning 216.4%. The upscale fiberglass grand entrance costs $11,754 and adds an estimated $9,959, or 84.7% recouped.
The grand entrance is a larger unit with sidelights and a wider opening. It still ranks tenth of 28, a good project, but it costs nearly five times as much and returns less than it costs. NAR's report tells the same story from the other side: a new steel front door recovers 100%, a new fiberglass door 80%.
The pattern across both reports is the same one that runs through the whole 2025 ranking: the modest replacement beats the upgrade.
The color question
Zillow's study is the only one of the three that isolates color, and it is worth reading for what it does not say. It does not say black doors are worth $6,449 everywhere. It says that when buyers were shown the same house with eleven door colors, the black-door version drew offers $6,449 higher than the baseline on a $334,141 home, slate blue and olive green also drew higher offers, and pale pink and cement gray drew the lowest. The study was run in 2022 with an online panel, not from closed sales.
What that supports: if you are choosing a color anyway, the evidence favors black, dark blue or deep green, and it argues against pale pink and flat gray. What it does not support: repainting a door you were not otherwise going to touch and expecting a specific dollar return.
What to do with this, by situation
Selling in the next 12 months. If the door is more than fifteen years old, dented, drafty, or clearly a different era from the rest of the facade, the steel replacement at $2,435 is the highest-confidence project in the report: two independent methods put it at or above 100%. If the door is sound, painting it in one of Zillow's three winning colors is a weekend and a quart of exterior paint.
Staying put. A new steel door is also insulation and security. Those benefits are real but were not measured by any of the three studies here, so they are not counted in the numbers above.
Already have a fiberglass grand entrance. Leave it. The 84.7% figure is the return on installing one, not a penalty for owning one.
The rule
Replace the door before you replace anything you cannot see from the street. If you only paint it, pick a color the buyers in Zillow's study bid up, not one they bid down.
