How much do single- and double-leaf patio doors cost?
Planning patio doors
Price is often the first concern when replacing a patio door or planning a new garden opening, but the door alone does not provide a dependable budget. Required clear opening width, connections to the wall, floor and outdoor surface, and fittings for everyday use all affect the project. A single hinged leaf may suit routine patio access; two leaves offer a broader opening but add hardware and coordination. Compare like-for-like scopes—not generic “patio doors”—covering dimensions, opening direction, glazing, leaf arrangement, threshold, hardware, installation and junction work. This turns an initial price estimate into a project budget that supports meaningful quotation comparisons.
Start with use, not the list price
The useful budget question is not simply, “What does a patio door cost?” It is, “Which opening needs to work in this room every day?” Mark the floor plan with the door open, plus the dining table, sofa, curtains and walking route. Outdoors, check whether an outward-opening leaf conflicts with furniture, steps, planters or a narrow patio. Only then can you judge whether one leaf is enough or a broad double opening offers real value. For direct, frequent access, a single inward-opening patio door can be a practical starting configuration if the room allows its swing. Also note how often the door will be opened and whether it is mainly for access, ventilation or a generous connection to the garden.
Consider the clear passage rather than only the structural opening or external door size. Frames and leaves take up width, while the centre section affects a two-leaf doorway. If large garden furniture, prams or serving trays need to pass easily, measure or test those situations specifically. A double door may suit a façade that is only occasionally opened wide. For routine individual access, the regularly used leaf matters more than the maximum opening on special occasions. Setting these priorities avoids paying for rare use while living daily with an awkward door leaf. Record essential requirements separately from nice-to-have features; this later helps reduce options without losing the core function.
Single or double doors: what each budget delivers
With a single hinged patio door, operation and locking are concentrated in one leaf. This can simplify everyday use and create a calmer appearance. Door width, leaf weight and available swing space must still suit one another. Outward-opening versions keep the interior clear, but require careful consideration of the outdoor area. As a product option for this direction, include a single outward-opening patio door in the request for dimensions and specifications. The opening direction alone is not decisive; it needs to work with paths, drainage, shading and furniture. A wide single leaf is not necessarily the easiest solution either: operation and structural suitability must be confirmed for the actual size.
A double patio door offers a different kind of opening: one leaf can serve daily use, while both open the frontage for visitors, ventilation or access to the garden. The second leaf is not simply “double the width”. Check leaf proportions, active and passive leaves, operating sequence, hardware, handing and the closed appearance. A double outward-opening patio door therefore needs to be costed as its own configuration, not as an enlarged single door. Ask the quotation to state which leaf is normally used, how the second leaf is released and what passage remains with only one leaf open. Also ask whether both leaves are equal or whether the active leaf is wider for more comfortable daily access.
Consider the whole opening
Dimensions make quotes comparable
Do not send a supplier only an approximate width and height. State whether these are the structural opening, the existing outside frame size or the desired finished size. Include wall construction, reveal depth, internal and external finishes, and photos of the complete opening. For replacements, images from inside and outside, of the threshold and upper reveal, are particularly useful. They can show early whether trims, sills, shutters, services or adjoining components may affect the work. A competent on-site measure remains essential before final ordering. Mark concealed areas and any components of unknown construction in the photos, so uncertainty does not quietly enter a fixed-price comparison.
The proportional division deserves separate attention. Equal leaves in a double door can create a symmetrical view, while unequal leaves can prioritise the daily passage. The more suitable arrangement depends on furniture, façade grid and intended use. State the desired handle side and opening direction from the room viewpoint as well. Vague descriptions such as “left” easily cause misunderstandings. A sketch showing the room as the viewing position and the leaves drawn in is better. Ask every quote to identify the widths, heights and leaf division assumed. Only then can you see whether a price difference reflects a real product difference or merely another dimensional assumption. Always check drawings against the actual room before approving a design.
Choose glazing, bars and appearance deliberately
Glazed area shapes daylight, outlook and the effect of the whole façade. It also affects leaf weight and technical planning. Instead of asking only for generally “better glazing”, describe the setting: strong sun, overlooking from neighbouring property, views, desired daylight and cleaning needs. The supplier can then offer a suitable configuration with understandable details. Compare values and construction for the complete quoted element, not from a single term in a brochure. Where the project includes an energy assessment, agree the target performance with the responsible professional. Also ask whether glazing choices affect leaf division, hardware or scope of supply instead of treating them as an isolated extra.
Glazing bars change more than the style. They may be applied to the surface or divide the glass, creating a different appearance and maintenance requirement. Use unambiguous terms in the quote: glazing bar, through-glazing bar or no glazing bars, and request an elevation drawing. In heritage-style projects, a traditional appearance may form part of the overall concept. A traditional-style double outward-opening patio door names that configuration, but does not replace checking dimensions, division and details at the particular building. Coordinate visible widths, handle height and neighbouring windows early so the door does not later look like an unrelated item. Record whether the drawing is viewed from inside or outside, because leaf and handle sides reverse with the viewpoint.
Test opening direction and hardware in daily use
Hinged doors need a clear arc. For inward-opening doors this affects the living room; for outward-opening doors, the patio. Do not imagine only the fully open position. The partly open position for passing through, ventilation in wind, carrying items and cleaning are relevant too. Check whether a rug, curtain or heater restricts movement. With a double-door design, establish whether the second leaf will be opened regularly or chiefly for special occasions. Trial-mark the swing arc on the floor with tape; conflicts with chairs, other doors and circulation paths usually become clearer than on a small plan.
Hardware and handles are not incidental accessory lines. They determine how the door feels to use, how it closes and which positions are possible. Explain who will use the door and how: young children in the household, limited hand strength, frequent carrying, pets or a patio used only seasonally all create different priorities. Ask which handles, locking arrangements and opening restrictors are included in the proposed configuration and how they operate. A sample handle or demonstration can clarify more than a photograph. Put special requests in writing before ordering. Later changes to hardware or opening direction can be substantially more involved because they affect construction, manufacture and installation. Decide whether outside operation is wanted, and have the proposed solution named clearly.
Plan the threshold, floor junction and water management together
How the internal floor, threshold and outdoor finish meet largely determines whether the door integrates well with the project. Floor build-ups, patio falls, overhead cover and existing steps are not minor details; include them in the quotation. Record proposed finished levels inside and out, plus any surfaces due for replacement. A photo with a tape measure is useful but does not replace accurate measuring. Tell the installer which junction surfaces will be present. If landscaping comes later, the door installer and patio or landscape contractor still need one agreed reference level.
Discuss connection sealing, fixings and protection of the lower area in specific terms. Those labels alone do not guarantee an appropriate solution; what matters is which work is included in each quote and who coordinates the interfaces. During renovation, removing the old door may expose reveals or floor junctions that were not visible beforehand. Agree how additional work discovered then will be handled and who authorises it. Where outdoor works are undertaken by another trade, both parties should receive the same level drawings. This reduces the risk that the door is installed properly but the following surface cannot later meet the threshold correctly. Before linings are closed, document completed junctions where this can be agreed with the involved contractor.
Consider the whole opening
Do not treat installation as a flat incidental item
Product and installation quotations may use different structures, provided their scope is clear. Ask for separate entries covering measurement, old-door removal and disposal, delivery, fitting, fixings, junction work, sealing materials, internal and external trims, and reinstatement of nearby surfaces. Confirm who protects the interior and whether flooring, plaster, painting or outdoor paving is included. A low total without this detail is hard to assess. Exclusions matter too: a concise list of omitted work often reveals the true budget more clearly than a broad “complete service” description.
Fitting the door into the building envelope requires coordinated responsibility. If the opening changes, ask suitably qualified local professionals to assess whether structural, approval or design requirements apply rather than relying on the door quotation. Coordinate shading, electrical connections, alarms and ventilation in the same way. For staged work, set the sequence: structural opening, measuring, order, removal, installation, junctions, then internal and external finishing. Bloomcabin states a five-year commercial warranty for windows and doors, plus delivery in four to six weeks subject to order confirmation. Record both beside the intended installation date. Where Australian Consumer Law applies, this warranty operates alongside rights that cannot be excluded. Nominate who checks the unit on delivery and receives reports of visible discrepancies.
Read quotes against a fixed framework
Before approaching suppliers, make one schedule of essentials and optional features. Essentials include leaf count, dimensions, opening direction, leaf proportions, appearance, glazing objective, handle side, threshold and installation conditions. Optional choices might cover a preferred glazing-bar pattern, finish or extra operating functions. Send the same schedule to each supplier, then assess the stated scope rather than relying on general descriptions. Mark omissions as unresolved instead of presumed inclusions. Add columns for departures and questions so you can tell whether a lower quotation matches the design or simply covers less work.
Check that prices use the same tax treatment and show measurement, installation, delivery, disposal and finishing separately. Request separate prices for variants such as one or two leaves, another opening direction or a different glazing-bar pattern. This exposes the cost of each choice without comparing unrelated proposals. A double inward-opening patio door may be a useful comparison option where the outdoor area should remain clear, but it is only fairly comparable if dimensions, glazing division and installation assumptions remain the same. Decide afterwards which options truly belong in the budget. Also compare the payment schedule, quote validity and process for changes, without confusing those commercial matters with technical quality.
Arrange total costs, allowances and follow-on work
A practical budget separates several allocations: door configuration, measuring and planning, delivery, installation, removal and disposal, junction work, and reinstatement of nearby surfaces. Add an allowance for conditions revealed only after removal. It is prudent planning rather than a price promise and can prevent small but necessary follow-on tasks from interrupting the project. Label every item as firmly quoted, estimated, owner-provided or unresolved. Keep essential work separate from comfort and design options. If funds tighten, you can reconsider glazing bars, finish or operating extras without inadvertently reducing the threshold connection or installation scope.
Also assess costs across the complete opening area. If an adjacent window needs adjustment, shading must move or patio paving is renewed, include this in the same decision. A single door can appear inexpensive while its chosen opening direction later requires changes to furniture or outdoor works. Where a large, flexibly opened frontage is the real aim, systems such as outward-opening folding doors are an alternative, not merely an option on the same hinged door. Likewise, classic sliding doors are another distinct system, with their own operating sequence. Compare alternatives by intended use, site conditions and total project scope, avoiding a visually appealing product paired with an unsuitable room or junction solution.
Make a structured decision from first measure to order
Begin with photographs, a dimensioned sketch and a list of everyday situations. Then arrange a professional assessment of the opening. Before ordering, confirm every visible decision: dimensions, number and division of leaves, opening direction, handle position, glazing, bar pattern, threshold connection, colour or finish, installation scope and responsibility at interfaces. Request an order drawing or equivalent written summary. Read it not only for overall width, but also for handing and the appearance of open leaves. Then cross-check the quote, drawing and order confirmation; resolve conflicting information before production approval rather than bridging it with verbal assumptions.
Allow adequate time between ordering, delivery and following trades. The stated four-to-six-week delivery period is subject to order confirmation, so the confirmed date for the specific order is the binding one. Do not wait until delivery day to organise access, a clear work area or coordination with flooring and outdoor works. For a new build or major renovation, it is worthwhile selecting the patio door with neighbouring windows. Grids, handle heights and glazing-bar views can then align. A Patio Life lift-and-slide door is a separate alternative where a large sliding access route matters more than hinged leaves. Make the system decision before selecting detailed fittings, not after comparing individual accessory prices.
Frequently asked questions
Is a double patio door always much more expensive?
A comparable two-leaf design needs extra components and coordination, but a fixed price difference would mislead. Dimensions, glazing, leaf division, hardware and installation all matter. Price both versions for the same opening and site conditions, with ancillary work separated, to reveal the meaningful difference for your project.
What dimensions does a supplier need for an initial quote?
State width and height, identifying each as a structural-opening, existing or desired dimension. Include internal, external, threshold and reveal photos, wall thickness, finished or planned floor levels, and an opening-direction sketch. A competent on-site measure is the more reliable basis for ordering and installation.
Should the patio door open inwards or outwards?
The clear swing space on the side where the leaf opens is decisive. Inside, furniture, curtains and circulation routes may interfere; outside, steps, paving, plants or roofing may matter. Draw the door into the floor plan and check everyday use with it partly and fully open.
What should the installation quote expressly include?
Clearly allocate measurement, delivery, removal and disposal of the old door, fitting, fixings, junction work and sealing. Also identify who reinstates internal plaster, trims, floor junctions and outdoor paving. Put unresolved boundaries between trades in the written project plan rather than a verbal side agreement.
When is a sliding or folding door better than a hinged door?
Where a broad opening, a different operating method or limited swing room is the priority, sliding or folding doors can be suitable alternatives. Do not choose them for appearance alone. Compare actual passages, room and patio conditions, intended opening frequency, connection details and the full installation scope with the hinged-door option.
Next step
For a single- or double-door patio opening, product price is only one part of the budget. A dependable decision combines a clear account of daily use, accurate dimensions, a chosen opening direction and a precisely defined installation scope. Two leaves are worthwhile when their wider opening and arrangement deliver a genuine everyday advantage; one leaf often provides simpler, direct operation. Request alternatives prepared on the same basis, read each item through to the threshold, junctions and follow-on work, and settle responsibilities before ordering. This makes the quotations genuinely comparable and helps the selected patio door suit the room, outdoor area and overall sequence of building work.
