CFP Carpentry & Fire Prevention were contacted to carry out an urgent fire door survey and remedial works at a flat in Salisbury. The work was required as part of the sale process, where the condition and compliance of the flat entrance fire door needed to be addressed quickly.
Following the survey, our team completed a series of remedial adjustments to bring the door closer in line with the required standard. This included removing the architraves, adjusting the frame with hardwood wedges, reducing the gaps around the door, installing a drop-down seal and setting the door closer so the door would close correctly from all angles.
CFP provides professional fire door services in Salisbury, including fire door inspections, remedial works, repairs and compliance support for flats, residential blocks and managed properties.
Urgent Fire Door Survey for a Flat Sale
The client needed the fire door checked and corrected urgently due to the sale of the flat. During property sales, fire door issues can often be raised during surveys, fire risk assessments or management company checks, especially where the door forms part of the flat entrance and protects the communal escape route.
Our team inspected the door, checked the gaps around the frame and reviewed how the door was closing. The door required remedial works to help achieve consistent 2-4mm gaps around the door and improve the way the door set performed.
Fire Door Remedial Works Completed
To correct the issues found during the survey, CFP removed the architraves and adjusted the door frame using hardwood wedges. This allowed the frame position to be altered so the gaps around the door could be brought closer to the required 2-4mm range.
The gap at the bottom of the door was also over the 3mm limit, so a drop-down seal was installed. This helps close the gap at the threshold when the door is shut, improving the overall performance of the fire door set.
Works Carried Out
- Urgent fire door survey completed
- Architraves removed to allow frame adjustment
- Hardwood wedges fitted to adjust the door frame
- Gaps around the door adjusted to help achieve 2-4mm
- Drop-down seal installed due to the bottom gap exceeding 3mm
- Door closer adjusted so the door closes correctly from all angles
Why Correct Fire Door Gaps Matter
Fire door gaps are an important part of fire door performance. If the gaps are too large, the door set may not provide the level of protection expected in the event of a fire. For flat entrance doors, this is especially important as the door protects both the flat and the communal escape route.
CFP carries out fire door remedial works where existing doors can be adjusted, repaired or upgraded without always needing a full replacement. This can include gap adjustment, closer adjustment, smoke seal replacement, drop-down seal installation, hinge works and other compliance-led repairs.
Door Closer Adjustment and Drop-Down Seal Installation
As part of this job, the door closer was adjusted to make sure the door closed properly from different opening angles. A fire door should self-close fully into the frame and not remain partly open.
The new drop-down seal was installed to deal with the excessive gap at the bottom of the door. These seals are designed to drop down when the door closes, helping to reduce the gap at floor level while still allowing the door to open and close smoothly.

Fire Door Support for Flats and Managed Properties
This Salisbury project is a good example of how smaller fire door issues can become urgent during a property sale. Gaps, closers, seals and frame alignment can all affect whether a fire door is considered suitable.
CFP provides fire door surveys and remedial works for flat owners, landlords, property managers and managing agents. We can inspect existing doors, identify faults and carry out practical remedial works where suitable.
