What do single- and double-leaf patio doors cost?
Planning patio doors
Anyone replacing a patio door or planning a new opening to the garden understandably asks about price first. Yet a single door price is not enough for a dependable budget decision. What matters is the opening width you genuinely need, how the door connects with the wall, floor and outdoor area, and which features suit daily life. A single-leaf hinged door may be the straightforward choice for everyday access to the patio. A double-leaf version creates a wider opening, but also brings a second leaf, extra hardware and more coordination. Rather than comparing one “patio door” with another, compare matching scopes: dimensions, opening direction, glazing, division, threshold, hardware, fitting and connection work. That turns an early price idea into a project budget that makes quotations genuinely comparable.
Start with how the space will be used, not the list price
The right budget question is not simply, “What does a patio door cost?” It is, “Which opening needs to work in this room every day?” Draw the plan with the door leaf open, including the dining table, sofa, curtains and walking route. Outdoors, check whether an outward-opening leaf would conflict with furniture, steps, planters or a narrow patio. Only then can you judge whether one leaf is sufficient or whether a wide double-leaf opening delivers real value. For direct, regular access, a single-leaf inward-opening patio door can be a practical starting configuration if the room allows the swing area. Also note how often the door is likely to be opened and whether it will mainly serve as an exit, for ventilation or as a generous connection to the garden.
Consider the clear passage, not only the structural opening or the door’s external dimensions. Frame and leaves take up width; with two leaves, the central meeting area affects the route through. If you want to move large garden furniture, prams or serving trays easily, recreate or measure those situations. A double-leaf door may suit a façade that only occasionally needs to open wide. For daily individual access, the actively used leaf matters more than the maximum opening on special occasions. This priority prevents you paying for infrequent use while living with an impractical leaf every day. Keep essential requirements separate from desirable features; this helps reduce specification options later without losing the core function.
Single or double leaf: what each budget supports
With a single-leaf 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 work together. Outward-opening designs free the interior, but require careful consideration of the outdoor area. As a product approach for this direction, a single-leaf outward-opening patio door can be included in your dimensional and specification enquiry. The opening direction alone is not decisive; it must work with paths, drainage, shading and furniture. A wide single leaf is not automatically the simplest solution, and its operation and structural suitability must be confirmed for the exact size.
A double-leaf patio door offers a different quality of opening: one leaf can serve everyday use, while both leaves open the frontage for visitors, ventilation or access to the garden. The second leaf is not simply “double the width”. Consider leaf division, fixed and active leaves, operating sequence, hardware, hinging and the closed appearance. A double-leaf outward-opening patio door should therefore be priced as its own configuration, not as an enlarged single-leaf door. Ask the quotation to state which leaf is used regularly, how the second leaf is released and what clear passage remains when only one leaf is open. Also ask whether both leaves are equal or whether the active leaf is wider for more comfortable everyday access.

Dimensions make quotations comparable
Do not send a supplier only an approximate width and height. State whether these are the structural opening, the existing frame’s outer dimensions or the desired finished size. Include wall construction, reveal depth, existing internal and external finishes, and photographs of the complete opening. For a replacement, photos from inside and outside, plus the threshold and upper reveal, are especially useful. They can reveal early whether trims, sills, shutters, services or adjoining components could affect the work. A competent on-site survey remains essential before final ordering. Mark concealed areas and components with an unknown build-up in your photographs, so uncertainty does not quietly enter a fixed-price comparison.
The proportional leaf division deserves separate attention. On a double-leaf door, equal leaves can create a symmetrical appearance; unequal leaves can prioritise the daily passage. The better option depends on furniture, façade rhythm and intended use. In your enquiry, state the desired handle side and opening direction as viewed from inside the room. Ambiguous terms such as “left” easily cause misunderstandings. A sketch showing the room viewpoint and the leaves is better. Ask every quotation to show the assumed widths, heights and leaf division. Only then can you see whether a price difference reflects a genuine product difference or merely a different dimensional assumption. Always check drawings against the real room before approving a configuration.
Choose glazing, bars and appearance deliberately
Glazed area shapes daylight, views and the effect of the whole façade. It also affects leaf weight and technical planning. Rather than asking only for generally “better glazing”, describe the setting: intense sun, overlooking from neighbouring property, views, desired light levels and cleaning needs. The supplier can then propose a suitable configuration with clear information. Compare values and construction for the complete quoted element, not from an isolated term in a brochure. If the project has energy requirements, agree target performance with the responsible local professional and the applicable SANS 10400-XA assessment. Ask whether glazing options affect leaf division, hardware or scope of supply instead of treating them as an isolated surcharge.
Glazing bars change more than the style. They may be applied to the surface or divide the glass; each approach creates a different appearance and maintenance requirement. Use clear terms in the quotation, such as applied bars, true divided-light bars or no bars, and request an elevation drawing. In period-property projects, a traditional look may form part of the overall concept. A traditional-style outward-opening double-leaf patio door names that configuration, but does not replace checking dimensions, division and details for the particular building. Coordinate sightline widths, handle height and adjacent windows early so the door does not later look like an unrelated item. Record whether the drawing is viewed from inside or outside, since leaves and handle sides mirror according to the viewpoint.
Test opening direction and hardware in daily use
Hinged doors need a clear swing arc. For inward-opening doors this affects the living space; for outward-opening doors, the patio. Do not imagine only fully opening the door. Half-open positions when passing through, ventilation in wind, carrying items and cleaning are also relevant. Check whether a rug, curtain or radiator restricts movement. With a double-leaf design, establish whether the second leaf will open regularly or mainly for special situations. Mark the swing arc on the floor with tape as a trial; conflicts with chairs, doors and routes often become visible faster than on a small plan.
Hardware and handles are not minor accessory lines. They determine the operating feel, locking sequence and how the door can be used in different positions. Describe 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 lead to different priorities. Ask which handles, locking arrangements and opening restrictors are included in the quoted combination and how they operate. A sample handle or demonstration may provide more clarity than a photograph. Put special requests in writing before ordering. Later changes to hardware or opening direction can be considerably more involved because they affect construction, manufacture and fitting. Decide whether operation from outside is required and have the offered solution clearly identified.
Plan threshold, floor junction and water management together
The transition between the internal floor, door threshold and external finish largely determines whether a patio door fits neatly into the wider project. Different floor build-ups, patio falls, roof cover and existing steps are not minor finishing tasks. They belong in the quotation stage. Record the planned finished floor levels inside and outside, and whether finishes will be renewed. A photograph with a tape measure helps, but does not replace an accurate survey. The fitting company needs to know which connection surfaces will actually exist at installation. If landscaping is completed later, door fitting and landscape or patio work still need a jointly agreed reference level.
Discuss junction sealing, fixing and protection of the lower area specifically. The terms alone do not guarantee an appropriate solution; what matters is which work each quotation includes and who coordinates the interfaces. In a renovation, removing the old door may expose reveals or floor junctions that were previously hidden. Agree how newly identified work will be handled and who authorises it. If the outside work is done by another contractor, both parties should receive the same level drawings. This reduces the risk that the door is professionally installed but the later finish cannot meet the threshold correctly. Before coverings are closed, document completed junctions where this can be agreed with the contractor involved.

Do not treat installation as a flat-rate extra
A product quotation and an installation quotation may be structured differently. That is not a problem if the scope remains clear. Ask for separate details of survey, removal and disposal of an existing door, delivery, positioning, fixing, connection work, sealing materials, internal and external trims, and reinstatement of adjoining finishes. Also ask who provides protection within the home and whether work to floors, plaster, painted surfaces or external finishes is included. A low total without this breakdown is difficult to assess. Explicit exclusions matter just as much: a short list of work not included often makes the real budget requirement clearer than a broad “complete” description.
Integrating a door into the building envelope requires coordinated responsibility. Alterations involving a changed opening may introduce structural, design and planning questions. Have these assessed by appropriately qualified professionals rather than inferring answers from a door quotation. Depending on the municipality and project, confirm the building-control approval route and relevant SANS requirements before work begins. The same applies to coordination with shading, electrical connections, alarm systems or ventilation plans. When works are phased, set the sequence: structure and opening, dimensions, order, removal, fitting, connections, internal and external work. Bloomcabin states a five-year guarantee for windows and doors. Delivery is stated as four to six weeks, subject to order confirmation. Record both alongside your desired installation date and decide who will inspect the element on handover and receive reports of visible discrepancies.
Read quotations using a fixed framework
Before making enquiries, create a sheet listing essential and optional points. Essential points include the number of leaves, dimensions, opening direction, leaf division, desired appearance, glazing objective, handle side, threshold and installation conditions. Optional items might include a particular bar style, finish preference or additional operating functions. Send the same sheet unchanged to every supplier you approach. You will then compare line items rather than descriptions. If information is missing, mark it as open instead of quietly assuming it is included. Add a column for differences and another for questions, making it clear whether a cheaper quotation describes the same build or simply lists fewer services.
Check in particular whether prices show the same tax treatment, whether survey and fitting are included, and whether delivery, disposal and finishing work appear separately. Ask for variants to be priced individually: for example, single versus double leaf, a different opening direction or another bar design. This shows the cost difference created by the decision without comparing two entirely different quotations. A double-leaf inward-opening patio door can be a useful comparison option if the outdoor area must remain clear, but it is only fairly comparable when dimensions, glass division and fitting assumptions remain the same. Only then decide which options truly belong in the budget. Compare the payment schedule, quotation validity and process for requested changes too, without confusing these commercial points with technical quality.
Organise total cost, allowances and follow-on work
A realistic budget has several pots: door configuration, survey and planning, delivery, installation, removal and disposal, connections and reinstatement of adjoining finishes. Add an allowance for findings that may only become visible after removal. This is not a price promise, but good planning discipline. It helps prevent a project stopping because of small but necessary follow-on work. For every item, note whether it is firmly quoted, estimated, provided by the client or still unclear. Separate necessary work from comfort and design options. If the budget becomes tight, you can then decide on bars, finish or operating extras without accidentally reducing the threshold connection or installation scope.
Also consider costs across the whole opening area. If an adjacent window must be adjusted, shading moved or the patio finish renewed, this belongs in the same decision framework. One door may appear affordable while its opening direction later requires changes to furniture or the outdoor layout. Where a large, flexibly opening frontage is the true goal, other systems such as outward-opening folding doors are alternatives, not merely a feature of the same hinged door. Likewise, sliding doors should be considered as independent system options with a different operating sequence. Compare such solutions by their use objective, installation conditions and complete project scope. This prevents an appealing product idea from being combined with an unsuitable room or connection solution.
Make a structured decision from first survey to order
Begin with photographs, a dimensioned sketch and a list of everyday situations. Then arrange a professional assessment of the opening. Before ordering, all visible decisions should be confirmed: dimensions, number and division of leaves, opening direction, handle position, glazing, bar layout, threshold junction, colour or finish, fitting scope and responsibility at interfaces. Ask for an order drawing or an equivalent written summary. Read it not only for overall width but also for hinging and the appearance of opened leaves. Then compare the quotation, drawing and order confirmation; resolve conflicting information before releasing manufacture rather than bridging it with verbal assumptions.
Allow sufficient time between ordering, delivery and the following trades. The stated delivery period of four to six weeks is subject to order confirmation, so only the confirmed date for your own order is binding. Do not wait until delivery day to organise access, a clear working area or coordination with floor and outdoor works. In a new build or extensive renovation, it is worthwhile deciding on the patio door together with adjacent windows. This allows sightlines, handle heights and bar layouts to align. A Patio Life lift-and-slide door is a separate alternative for a project where the priority is a large sliding access rather than hinged leaves. Make the system decision before choosing detailed features, not only after comparing individual accessory prices.
Frequently asked questions
Is a double-leaf patio door always much more expensive?
Compared with a similar single-leaf version, it requires additional components and coordination, but quoting a fixed price difference would be misleading. Dimensions, glazing, leaf division, hardware and installation all matter. Have both options priced for the same opening, identical installation conditions and clearly separated ancillary work. Only then will the difference be meaningful for your project.
Which dimensions does a supplier need for an initial quotation?
Give the width and height, explaining whether these are structural, existing or desired dimensions. Add photographs from inside and outside, of the threshold and reveals, wall thickness, finished or planned floor levels, and a sketch of the opening direction. A competent on-site survey is the more reliable basis for ordering and fitting.
Should the patio door open inwards or outwards?
The key factor is clear swing space on the side where the leaf opens. Indoors, furniture, curtains and routes can obstruct it; outside, steps, finishes, plants or a roof cover may be relevant. Draw the door into the floor plan and test everyday use with the door half open and fully open.
What should the installation quotation explicitly include?
At minimum, survey, delivery, removal and disposal of the old door, positioning, fixing, connection work and sealing should be clearly allocated. Also establish who reinstates internal plaster, trims, floor junctions and the external finish. Open interfaces between trades belong in the written project plan, not in an informal verbal arrangement.
When is a sliding or folding door more suitable than a hinged door?
When a wide opening, a different operating sequence or limited swing space is the main priority, sliding or folding doors can be suitable alternatives. They should not be selected for appearance alone. Compare actual passages, room and patio conditions, intended opening frequency, connection details and the complete installation scope with the hinged-door option.
Next step
For budgeting a single- or double-leaf patio door, the product price is only one component. A sound decision comes from a clear description of use, precise dimensions, a defined opening direction and a clearly limited installation scope. A double-leaf door is worthwhile where the wider opening and leaf division create a real everyday advantage; a single-leaf door often succeeds through simple, direct operation. Request variants on the same basis, read every item through to the threshold and connection work, and clarify responsibilities before ordering. The quotation then becomes not merely comparable: the chosen patio door will suit the room, patio and the complete construction sequence.
