What do frameless
sliding doors cost?
The price depends on your opening, the way the panels move, the glass specification and the work needed to install them. A useful quotation starts with a clear, shared brief.
Use this guide when planning a London project or comparing proposals elsewhere. For current pricing, request a quotation for your own dimensions and requirements.
Request a project quotation ↗Considered design. Everyday value.
FineLine frameless sliding doors combine refined design, smooth operation and value for money. British-made, with a choice of glazing for solar control and security, they suit standalone installations or a coordinated whole-property glazing solution—creating expansive views and a closer connection to the outdoors.
Typical delivery: 6–8 weeks, with the programme confirmed for your project.
Compare the complete installed scope.
A price per square metre is only useful when you know what it covers. Two quotations for the same opening can include different door arrangements, glass, delivery and installation work. Compare the specification and exclusions alongside the total.
This guide explains the cost factors rather than giving a generic price range. FineLine confirms current prices through a project-specific quotation.
Six details to agree before comparing quotes.
1. Opening size and panel arrangement
Overall width and height are the starting point. The number of moving and fixed panels, track arrangement and required clear opening shape the system. Ask for a drawing showing the closed and fully open positions.
2. Glass specification
Solar control, low-iron glass, laminated build-ups and double or triple glazing can change the specification and cost. Choose around orientation, safety requirements and comfort, and compare the proposed glass build-up and whole-system performance.
3. Corner openings and structural work
An open corner needs coordination between the doors and the structure above. Establish whether the quotation includes structural design or building work, and who is responsible for preparing and supporting the opening.
4. Thresholds, drainage and floor levels
A flush-looking transition involves the track, internal floor, external paving and drainage. Confirm the proposed detail and whether recesses, waterproofing, paving alterations and making good are included.
5. Delivery and installation access
Large panes need a suitable route to the opening and an agreed handling plan. For a London property, tell the team about narrow side access, steps, restricted parking or a route through the house. Confirm whether lifting equipment and any access arrangements are allowed for.
6. Finish, hardware and aftercare
Agree frame finish, handles, locking and any other options. Check the installation scope, warranty terms and servicing arrangements so you understand both the initial proposal and what follows.
What should a clear quotation tell you?
- The opening dimensions and a drawing of the proposed panel layout.
- The glass build-up, finish, hardware and specified performance.
- Whether survey, design, delivery, lifting and installation are included.
- Who handles structural work, drainage, waterproofing and making good.
- Whether VAT is included, plus any exclusions or provisional allowances.
- The payment stages, quotation validity, estimated programme and warranty terms.
If a detail is missing, ask for it in writing before comparing totals. A lower figure can reflect a different scope, rather than an equivalent installation.
Make the first conversation useful.
Can I get an initial quote before a site survey?
Send your postcode, photographs, drawings and approximate dimensions to start the discussion. Label measurements as preliminary and identify anything still undecided. Final dimensions and installation details need confirmation through the agreed survey and design process before manufacture.
Are corner-opening doors priced the same as a straight opening?
They should be assessed separately. A corner changes the layout, sealing details and coordination with the supporting structure. Ask for a quotation for the configuration you intend to build.
How do I stay within my budget?
Explain your budget and priorities early: the view, clear opening, ease of operation and comfort. Ask the team to compare suitable panel layouts and glazing options, keeping the required safety and performance in the brief.
Does a London location change the price?
Site access and installation logistics can affect the scope. The relevant details are the actual property, access route and working arrangements, rather than the postcode alone.
What should I send with my enquiry?
Share the postcode, approximate opening width and height, photographs or drawings, your preferred layout and intended timescale. Include what you know about floor levels and access, plus any questions about glass or installation.
