Jemmy marks are a common form of damage caused during burglaries and attempted break-ins, typically when a crowbar, screwdriver or similar tool is used to force open a window or door. These tools can leave deep dents, scratches, gouges and damage to the surrounding frames, affecting both the appearance and security of your property.
Window Doctor provides professional jemmy mark repairs through our nationwide network of local branches, helping homeowners and businesses restore damaged uPVC, aluminium and timber windows and doors.
Our specialist repair engineers can assess damage caused by forced entry and, where appropriate, repair the affected surfaces without replacing the entire window, door or frame.
Using specialist repair techniques, including reshaping, filling, smoothing and colour matching, we aim to restore damaged areas to a neat, professional finish while ensuring the window or door remains secure and operates correctly.

Common Types of Jemmy Mark Damage We Can Repair:
Jemmy marks are generally caused by tools being forced between a window or door and its surrounding frame. Depending on the force used, the resulting damage can range from minor surface marks to significant distortion.
Common types of damage include:
- Crowbar marks – deep dents and gouges caused by tools used to force windows or doors open.
- Screwdriver damage – scratches, chips and indentations around frames and locking points.
- Dented uPVC frames – compressed or distorted surfaces caused by attempted forced entry.
- Scratched window and door frames – visible surface damage left by metal tools.
- Chipped or gouged surfaces – sections of frame material damaged or displaced during a break-in.
- Damaged door edges – marks and distortion around the areas where doors meet their frames.
- Damaged window frames – forced entry can leave visible marks around opening sashes and surrounding frames.
- Distorted locking areas – excessive force can damage the frame around locks, keeps and locking mechanisms.
- Windows or doors that won’t close properly – damage or movement caused by attempted entry can affect alignment.
- Damage to surrounding glazing – severe break-in attempts can also crack or shatter glass.
Although jemmy marks can look extensive, surface damage doesn’t always mean the entire window or door needs replacing. However, where forced entry has damaged structural components or compromised the locking system, these issues must be addressed before cosmetic repairs can be considered complete.

Frequently Asked Questions - FAQs
What are jemmy marks on windows and doors?
Jemmy marks are dents, scratches, gouges or other damage caused when a crowbar, screwdriver or similar tool is used to force open a window or door. They commonly occur around frames, locking points and the edges of opening sections during burglaries or attempted break-ins.
Can jemmy marks on uPVC windows and doors be repaired?
Yes. Many types of surface damage to uPVC windows and doors can be repaired using specialist techniques such as reshaping, filling, smoothing and colour matching. However, the extent of the damage must be assessed to establish whether any structural or security components also require attention.
Do I need to replace my door or window frame after a break-in?
Not necessarily. Where the damage is primarily cosmetic and the existing frame remains structurally sound, specialist repairs may be possible. If the frame, locking points or other security components have been seriously damaged, additional repairs or replacement parts may be required.
Can you repair crowbar damage to aluminium and wooden frames?
Yes. Window Doctor provides suitable jemmy mark and forced-entry damage repairs for uPVC, aluminium and timber windows and doors. The repair techniques will vary depending on the frame material and severity of the damage.
Will my insurance cover jemmy mark repairs?
Jemmy mark repairs following burglary or attempted forced entry may be covered by your buildings insurance, depending on your policy. Window Doctor can provide a repair quotation and relevant information to assist with your claim, but your insurer will determine whether the damage is covered.
