What Impact Damage on Doors Usually Looks Like
Most impact damage on doors falls into two groups: dents, holes and cracks in timber doors, and scuffs, scratches and edge chips on uPVC and composite doors. Both are often repairable in place, and knowing which type you have is the first step in understanding how to fix impact damage on doors.
A door takes more punishment than almost any other surface in a building. It gets kicked, bumped by trolleys, caught by furniture and slammed by wind.
Dents, holes and cracks in hollow and solid doors
Hollow doors have a thin skin over a card or timber core. A hard knock can dent that skin or punch straight through it. Solid doors dent and split instead, and the split often runs along the grain.
Watch out: a hole in a hollow door usually means the core behind it has crushed. Filling the face without rebuilding that backing gives you a soft patch that fails within weeks.
Scratches, scuffs and edge damage on uPVC and composite doors
uPVC and composite doors rarely dent. They scratch, scuff and chip at the edges instead. Keys, bags and pushchairs cause most of it. The colour sits in the surface, so a deep scratch shows as a pale line.
If your frames or sills are marked too, our alternatives to replacing scratched uPVC frames sets out what actually works.
Which Door Materials Can Be Repaired and Which Cannot
Suitability depends on the extent of the damage, the door's construction and where it sits. Surface Magic Repairs assesses each door honestly before booking anything.
Here is how the main door types tend to behave:
| Door type | Typical damage | Usually repairable? |
|---|---|---|
| Hollow timber | Dents, punch holes, split faces | Often, if the core is rebuilt |
| Solid timber | Dents, splits, edge chips | Often, including colour matching |
| uPVC | Scratches, scuffs, edge chips | Often, with refinishing |
| Composite | Surface chips, scuffs | Often, subject to assessment |
| Laminate-faced | Chips, lifted edges | Sometimes, depends on the core |
| Fire doors | Any damage to the leaf or seals | Rarely, certification comes first |
Fire doors are certified products, so any damage affecting the leaf, frame or seals should be assessed before any work is considered.
For uPVC frames, cills and trims, our uPVC frame and cill repairs cover chips, scratches, dents and burns without disturbing the glazing.
Step-by-Step: How Professionals Fix Impact Damage on Doors
Repairs are typically assessed, prepared, rebuilt, colour matched and refinished, and are normally completed on site with the door left in place.
The sequence matters more than any single product. A repair that skips a stage, or rushes one, tends to fail at the weakest point within a few months. Here is what each stage involves and why it is done that way.
Assessment and preparation
First, we check what is behind the damage. Is the core sound? Is the frame affected? Does the door still close and latch properly?
Then we prepare the area. Loose material comes out, edges are keyed back and dust is removed. Skipping this step is the most common reason a repair fails early.
Rebuilding the damaged area
Hollow and solid doors are rebuilt differently. A hollow door with a punched hole usually needs the crushed core behind the skin replaced or backed with a solid insert before the face is filled. Without that backing, the filler has nothing to sit against and will flex and crack the first time the door is knocked. A solid door is built up in thin layers, each allowed to cure, so the filler shrinks back consistently rather than sinking into a hollow.
Deep edge damage is rebuilt in the same staged way, because edges take the most knocks and a single thick fill will chip out.
Colour matching and refinishing
Colour matching is important for a neat result, as a patch that looks right under one light can look obvious in another. Surface Magic Repairs matches the colour and finish to the existing surface.
How long a repair usually takes
Repair timescales depend on access, the number of doors and the finish required. Surface Magic Repairs confirms the likely timescale when it assesses your photographs.
The Cost of Repairing Damaged Doors vs Replacement
Repair is generally less expensive than replacement, because it avoids much of the strip-out, disposal and redecorating that replacement involves.
The cost of repairing damaged doors vs replacement depends on the door type, the number of repairs, access and the finish required. We cannot quote a fixed figure without seeing the damage.
What we can say is what drives the difference:
- Replacement: new door, fitting, disposal, making good, redecorating
- Repair: assessment, preparation, filling, colour matching, refinishing
- Downtime: replacement can take a door out of use for a day or more; repair is often same-day
Where the money actually goes
Replacement costs can include fitting labour, disposal and redecorating, while repair avoids much of this. Less waste going to landfill is another benefit of repairing rather than replacing.
The downtime cost that rarely appears on a quote
For hotels, landlords and facilities teams, downtime is often the bigger cost. A room out of action costs more than the door. Our guide to the benefits of repairing vs replacing fixtures covers that trade-off in more detail.
A replacement door has to be ordered, delivered and fitted, and the room or corridor may be out of use while that happens. A repair done in place usually keeps the door hung and the space usable, which is why planned repair programmes appeal to property managers and housing associations maintaining occupied buildings. The same logic applies to new-build snagging, where replacing door leaves on a live site delays handover.
When repair is not the cheaper option
Repair is not always the economical choice. Where damage affects structure or certification, replacement may be more appropriate, and an honest assessment will say so.
What affects your quotation
The main factors are the material, the number and depth of the repairs, access and the finish required. Photographs of the damage plus your full address and postcode let Surface Magic Repairs assess suitability and provide a quotation. Send them to info@surfacemagicrepairs.com or call 0800 085 7773 during office hours, Monday to Friday, 9:00am to 3:00pm.
Snagging Repairs for New Build Doors
Snagging repairs for new build doors are cosmetic fixes made before handover, when doors have been scuffed, chipped or marked during the build. They are usually cheaper and faster than replacing door leaves on a live site.
Doors can carry scuffs and edge chips by the time a new-build plot is ready. Surface Magic Repairs can work alongside site managers and customer-care teams to repair damage in place, which avoids the need to wait for replacement doors to arrive.
What Information Is Needed for a Quote
To quote a door repair, we need clear photographs of the damage, the whole door and the surrounding frame, plus your full address and postcode. With those, we can usually tell you whether a repair is suitable.
Photographs do most of the work. Take them in daylight, in focus, and include something for scale. Our guide to how to prepare photos for a repair quote explains exactly what to send.
Helpful details include:
- Door material and type
- How many doors are affected
- Whether the door still closes and latches
- Whether it is a fire door
- Access arrangements and site hours
Send these to info@surfacemagicrepairs.com or call 0800 085 7773 during office hours, Monday to Friday, 9:00am to 3:00pm.
When Replacement Is the Better Option
Replacement is the better option when the door's structure, security or fire performance is compromised. In those cases a cosmetic repair would only hide a bigger problem.
Surface Magic Repairs will advise honestly if that is the case. Signs that may point to replacement include:
- A twisted or warped leaf that no longer fits the frame
- Rot through the timber, not just at the surface
- Damage to a fire door leaf, frame or seals
- A hollow door where the core has collapsed across a wide area
- Hinges or locks pulling out of failed timber
Repairing a door that should be replaced wastes money. An honest assessment saves it.
Protecting Repaired Doors After the Work Is Done
A repaired door lasts longer with a few simple habits, as most repeat damage comes from the same causes.
- Fit a door stop or buffer where trolleys and furniture pass
- Use protective sheets during decorating and moves
- Wipe marks with a soft cloth, not abrasives
- Keep door edges clear of keys and bags
- Check door closers so doors do not slam
Give the finish time to cure before cleaning.

Frequently Asked Questions
Can impact damage on internal doors be repaired?

Surface Magic Repairs matches the colour and finish of the existing surface so the repair blends in. Suitability always depends on the extent of the damage, so send photographs for an honest assessment.
Is it cheaper to repair a dented door or replace it?
