Door problems, explained
Why Is My Front Door Peeling?
Peeling means the finish has lost its grip on the wood. There are only two things that cause that: sunlight broke down the wood surface underneath the film, or water got in behind it. On most doors in this area it is both. The coating itself is rarely the thing that failed first, which is why scuffing the loose edges and brushing on another coat almost never holds. The failure is at the bottom of the film, where it meets the wood, and you cannot fix that from the top.
The good news is that peeling is a finish problem, not usually a door problem. A solid mahogany, oak or old-growth fir door with a coating peeling off it is still a good door. Below is how to read yours, how urgent it is, and what it takes to put it right.
Why is my front door paint peeling?
Start with sunlight. Lignin is the natural glue holding wood fibers together at the surface, and it begins photodegrading within hours of UV exposure (USDA Forest Service, Wood Handbook chapter 16). UV passes straight through clear coats and works on thin or worn paint films too. As the lignin breaks down it leaves loose cellulose fibers on the surface. Your finish is now stuck to loose fibers instead of sound wood, and it only has to be nudged to let go.
Then water does the nudging. Dulles averages about 118 separate rain events a year (NOAA NCEI climate normals), plus roughly 90 freeze-thaw cycles, derived from NOAA daily records, 1991 to 2020. Water finds a check in the wood or an unsealed top or bottom edge, swells the fibers, freezes, and lifts the film off in sheets. Old thick paint makes it worse. As the National Park Service puts it in Preservation Brief 10, thick paint fails at the oldest layers next to the wood.
How bad is it? Three checks you can do in five minutes
First, slide a fingernail or a putty knife under a lifting edge and push gently. If it lifts a coin-sized flake and stops, the failure is local. If it peels away a long strip or a whole panel, adhesion is gone across that whole area and spot repair is off the table.
Second, turn a chip over and look at the back. Wood fiber stuck to the underside means the wood surface itself failed, not the coating. That is the classic clear-finish failure described in the Wood Handbook, and it means bare-wood stripping, not a recoat.
Third, look at the color of the exposed wood. Honey or tan means it just came off and the wood underneath is still sound. Silver gray means it has been open to the weather for months. Black, soft or spongy, especially in the bottom six inches, means water damage, and you should read our page on water damaged door bottoms before doing anything else.
What happens if I leave a peeling door for another year?
The bare patches are the problem, not the flakes. Once wood is exposed it starts weathering, and weathering permanently ruins how well any future finish will stick. The Forest Products Laboratory tested this directly: boards left bare for 16 weeks before painting peeled again within 3 years, while boards left bare for only 1 week held for 13. The Park Service says the same thing more bluntly in Preservation Brief 47, warning against leaving exposed wood unfinished for any length of time.
So a door you could have refinished this spring becomes a door that needs more sanding next spring, and the year after that water is into the end grain at the bottom rail and the stiles, joints open up, and veneer doors start to delaminate. That is the point where a refinishing job turns into a repair job, or a replacement quote. The cost curve is steep and it only goes one way.
Can I fix a peeling front door myself?
Sometimes, and we will be straight about when. Do it yourself if the peeling is confined to one panel or the lower rail, the wood under the flakes is still tan, the door is painted rather than stained, and you have a warm dry stretch of days. Scrape back to sound edges, feather the transitions with 120 grit, spot prime the bare wood, and put two full coats over the whole face so the repair does not read as a patch.
Do not attempt it if any of these are true. The door is stained, because spot repairs in stain never blend and you will see every edge. The door is veneered, which most doors built from the 1980s onward are, and one careless pass with an orbital sander goes straight through the face veneer. More than about a third of the door is failing. Or the wood is soft anywhere. And never power wash a door. Preservation Brief 47 is explicit that it drives water into the wood and into the wall behind it.
What does a professional peeling door repair actually involve?
Every layer comes off. We use chemical stripper rather than aggressive machine sanding, because stripper does not thin a veneer or round off the crisp edges of the panel profiles and the sticking. Faces, edges, panel returns and the raised moldings all get stripped, then the door is hand sanded to a clean even surface and checked for moisture before anything goes back on.
Checks and splits get filled, damaged sections of rail get repaired, and the top and bottom edges get sealed. Those two edges are where doors drink water and they are the most commonly skipped surfaces in this trade. Then stain is color matched on your own door, in daylight, where you can look at it, and the film is rebuilt in multiple coats of UV-stable exterior topcoat. It happens at your house, the opening is never left standing open, and the door is back on its hinges the same day with a one-year written warranty.
What does it cost to fix a peeling front door?
A single entry door runs $550 to $1,400. Double doors and French doors run $950 to $2,200. A wood garage door runs $1,200 to $3,200. Where you land inside those bands depends on size, how many panels and moldings there are, how many coats of old finish have to come off, and whether the bottom rail needs repair.
For comparison, replacing a wood entry door with something equivalent runs $3,500 to $8,000 or more installed, and that number does not include repainting the frame and trim to match. If your door is a solid slab in sound condition with a failed coating on it, replacing it is buying new wood to solve a coating problem.
The fastest way to get a real number is to text a photo of the door to (202) 979-9977, taken square on in daylight, plus one close shot of the bottom rail.

Questions
Frequently Asked Questions
Can I just paint over a peeling front door?
No, and it usually makes the next repair more expensive. New paint bonds to whatever it lands on. If it lands on a layer that is already letting go of the wood, it comes off with that layer, and now you have one more coat of old film for someone to strip later. Painting over peeling also traps the moisture that caused the peel. The only honest fix is to take the failed film off, get back to sound wood, and rebuild from there.
Does peeling mean my door is ruined?
Almost never. Peeling is a coating failure sitting on top of wood that is usually still sound. Press a fingernail into the bare patches. If the wood is firm and takes a light dent but does not crush, the slab is fine and it just needs stripping and refinishing. The exceptions are doors where water sat long enough to rot the bottom rail, and hollow veneered doors where the face layer has blistered away from the core. Both are visible from a photograph.
Why is only the bottom half of my door peeling?
Because that is where the water is. Rain bounces off the porch floor or the stoop and hits the lower third of the door, snow sits against it, and the bottom edge wicks moisture up through end grain if it was never sealed. Meanwhile the top half only takes sun. Doors under a shallow overhang or with no storm protection show this split very clearly. The finish fails from the bottom up, usually starting at the bottom rail and the lower panel.
The outside of my door is peeling but the inside looks new. Why?
The inside face never sees UV, rain or temperature swings, so the same finish applied on the same day can last decades indoors and two years outdoors. It is a useful reference, though. The interior face shows you what the original color and sheen actually were, which makes color matching far more accurate. Do not let a perfect interior face convince you the door only needs a light touch up outside. The two sides are living in different climates.
How long does it take to fix a peeling door?
Most single entry doors are stripped, repaired, stained and top-coated in one working day at your house. Double doors and heavily built garage doors can run longer. The door stays on its hinges for stripping and sanding and moves onto a padded stand a few feet away for coating, so your entry is never left open overnight. Cold or wet weather stretches recoat times, so we schedule around the forecast rather than pushing a finish that will not cure.
