Start with the way the pair operates
Tell us whether both leaves open regularly or one normally stays closed. Photograph the doors open and closed, including the centre joint and visible hardware. This shows how the existing sealing system is arranged.
An astragal or meeting-stile assembly may be fitted at the centre. Different designs interact with the door hardware in different ways, so replacing it requires more than matching the visible width.
Connect the centre seal to the perimeter
Air can enter at the frame, under either leaf or where the centre seal ends. Treating one spot in isolation may leave another gap. We review the opening and discuss the parts relevant to the symptom you describe.
If only one leaf has dropped or needs extra force to close, mention it. Alignment and closing behaviour help determine whether seals alone are the right repair.
For homes and commercial entrances
Residential French doors and storefront pairs can look similar from a distance but use different hardware and sealing profiles. We review the door construction, attachment method and clearance before confirming the proposed work.
Identify any labels or special operating requirements when you contact us. For automatic or labelled assemblies, compatibility needs to be assessed for the actual door system.
Make your estimate request easier
Include a full photo of the pair, a close-up of the centre strip and both lower corners. Add your location and explain which leaf is used most often. If you have several pairs, number the openings.
We will discuss whether the work concerns a seal, the existing assembly or another door-fit issue. The team confirms parts, price and appointment arrangements directly with you.
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.
