Secondary Glazing Seal Replacement in Sudbury — replacing seals around the secondary-glazing perimeter; assessing reveal dimensions
The original profile and compression are checked alongside panel alignment. A suitable replacement should close the gap without making the window difficult to move or latch.
The detail that matters
Will a general foam strip be an adequate substitute?
An unsuitable thickness or profile can obstruct operation, so the replacement needs to match the system's requirements.

Before the work
is agreed.
Will a general foam strip be an adequate substitute?
An unsuitable thickness or profile can obstruct operation, so the replacement needs to match the system's requirements.
Why check alignment when only the seal looks worn?
A poorly positioned panel can leave uneven gaps that new sealing material alone will not correct.
What should I include in this enquiry?
Send photographs of the whole window and room-side reveal, including handles, shutters and blinds. Give the postcode and explain whether noise, heat loss or another concern is driving the enquiry.
How is the quotation worked out?
The secondary system, opening arrangement, pane specification, dimensions and fixing surface affect price. Include any primary-window repair or relocation of fittings as separate agreed items.
Does the original window need its own condition check?
An inner layer does not repair decay, broken glass or faulty hardware in the retained window; those issues should be identified independently.
What access should the final layout preserve?
Agree how the primary window will be reached for operation and cleaning, and how the secondary panels will be maintained or removed where applicable.
When can the work be arranged?
For secondary glazing seal replacement, confirm current assessment and supply times for your postcode. A first visit, made-to-order materials and the completed work may have different dates.
