Plan the work around the entrance
Tell us whether the door serves a shop, office, common area or service entrance. Door material, traffic and the operating hardware affect the repair. Photos from both sides help us understand the opening before arranging the next step.
For several entrances, label each photo with a door number or location. A simple opening list helps separate a worn bottom sweep from a perimeter seal issue and keeps the proposed scope clear.
Perimeter, bottom and meeting-edge seals
A commercial opening can have several different sealing components. We assess perimeter gasketing at the frame, the sweep or bottom seal, the threshold contact and, for pairs, the area where the leaves meet.
Brush and flexible inserts have different profiles and mounting arrangements. We review the existing hardware and available clearance before recommending a replacement. Colour and finish can be discussed once a suitable profile is identified.
A sealing repair must respect door operation
A larger seal is not a substitute for a door that has dropped, a loose hinge or a closing problem. We check how the door moves and explain when adjustment or another repair should be considered alongside the seals.
Tell us if an opening is automatic, labelled as fire-rated, or part of an exit route. Compatibility and the appropriate work need to be assessed for that specific assembly; we do not describe a standard weatherstrip as a universal solution for these doors.
For property managers and business owners
Share the site address, an on-site contact, the number of doors and any access restrictions. If a tenant or manager must authorize the work, let us know at the enquiry stage. Opening hours help us discuss a suitable service arrangement.
The estimate should identify which openings and components are included. Any additional alignment, threshold or hardware work is discussed before it is carried out. A request for an estimate is not a reserved appointment.
Check the result where it matters
After the agreed work, the door should be checked through its normal closing cycle. Contact at the seal, movement across the threshold and latching all matter. Tell the technician about any existing operating issue rather than treating it as unrelated to the draft.
If the same gap returns, record the location and whether the door has started rubbing or closing differently. That information is more useful than simply adding another layer of material.
Not sure which part you have?
That is fine. Start with a photograph and tell us what the door is doing. We can help identify the next step.
