Published by Bifoldsandmore / Door Central Ltd · Updated 11 October 2026 · About our advice
01 · Explore
Draw the furnished room and list what needs to improve. Compare a normal weekday with the occasional fully open arrangement.
Keep this
A short priority list, photographs and a rough plan.
Avoid this delay
Choosing a brand before deciding how the opening should work.
02 · Budget
Request the same scope from each supplier. Keep costs for product, survey, handling, fitting and finishes separate.
Keep this
Itemised quotations with exclusions and unknowns marked.
Avoid this delay
Comparing a product-only starting price with an installed total.
03 · Survey
Confirm who measures and who coordinates floors, structure, roof details and access. Resolve differences between plans and site.
Keep this
A survey record and the agreed current drawing set.
Avoid this delay
Treating approximate enquiry measurements as order dimensions.
Agree responsibilities before agreeing dates.
Your builder, glazing supplier and installer need the same current information. Ask one person to maintain the opening schedule and outstanding actions. A target completion date is useful; it only becomes a reliable programme when the survey, approvals, manufacturing and site-readiness dependencies are clear.
04 · Approve
Review every opening reference, quantity, size, viewing side, operation, glass, colour and hardware. Get revisions in writing.
Keep this
Approved specification, price and applicable order terms.
Avoid this delay
Approving an old drawing after a verbal change.
05 · Prepare
Confirm the delivery and installation arrangements, safe access, receiving contact and site readiness.
Keep this
A shared plan for dates, handling and unfinished work.
Avoid this delay
Assuming free delivery includes all lifting and movement to the opening.
06 · Handover
Operate each unit with the installer, record unresolved items and collect the care and support documents.
Keep this
A snag record, instructions, warranties and first contact.
Avoid this delay
Leaving without knowing how to operate or report a problem.
How long will the process take?
Timing depends on the selected system, finishes, glass, manufacturing arrangements and readiness of the site. Ask for a current lead time tied to the approved specification, and establish when that period starts. A quoted lead time before final survey may not be the confirmed order programme. Avoid booking dependent finishing work against an unconfirmed delivery date.
Choose your next task
Supply only or supply and installation?
Supply only suits a project with a capable installer and clear ownership of survey, ordering and site coordination. Supply and installation can simplify the handoffs, but the written scope still needs to define building work and making good.
READ THE GUIDEFrom approximate measurements to an approved order
The survey turns a design idea into a buildable specification; order approval authorises the agreed product. Treat them as separate checkpoints, with one current drawing set and a named person responsible for the final dimensions.
READ THE GUIDEGlazing site-delivery checklist
Free delivery does not automatically include every activity required to get glazing into its opening. Confirm vehicle access, unloading, handling equipment, receiving checks and storage before a delivery date is agreed.
