A window replacement in Vienna costs €750 to €1,800 per window including removal, installation and plastering in. PVC costs €750 to €1,100, timber €950 to €1,500, timber-aluminium €1,200 to €1,800. Refurbishing an existing box-type window costs €900 to €2,200 and is often the only permissible solution in protection zones. What determines the result is not the window but the installation: airtight on the inside, driving-rain-tight and vapour-permeable on the outside. A high-quality window with a poor junction is worse than a simple one with a good junction.

Materials compared

Material	Price per window	Service life	Maintenance	In a protection zone
PVC	620–1.100 €	30–40 years	none	usually not permitted
Timber	950–1.500 €	40–60 years	painting every 8–12 years	permitted with matching glazing bars
Timber-aluminium	1.200–1.800 €	50–70 years	rarely inside, none outside	depending on the elevation
Aluminium	1.100–1.700 €	50+ years	none	rarely permitted
Box-type window refurbished	900–2.200 €	another 40+ years	painting every 10–15 years	always permitted, often required

Calculated over the service life, PVC and timber-aluminium are closer together than the purchase price suggests. In Vienna, the decisive factor is often not the material anyway, but what MA 19 permits.

Box-type windows: replace or refurbish

In Viennese Gründerzeit buildings this question arises on almost every project. It is often answered too quickly in favour of replacement.

Criterion	Refurbishing box-type windows	Installing a new window
Cost per window	900–2.200 €	750–1.800 €
Achievable U-value	1.3–1.8 W/m²K	0.8–1.1 W/m²K
Sound insulation	very good, two layers with an air gap	good to very good, depending on the glazing
In a protection zone	always permitted	only with a matching elevation
Preservation of the fabric	complete	irretrievably lost
Reveal depth and light	remains	frame becomes wider, glass area smaller
Service life	another 40+ years	30–50 years

The sound insulation of old box-type windows is underestimated. Two window layers with an air gap of 15 to 25 cm between them often insulate against traffic noise better than a modern single window with triple glazing. Anyone living on a noisy street may sometimes lose peace and quiet by replacing them.
The U-value is worse, but not disastrous. A refurbished box-type window with seals and a low-e pane in the inner sash achieves 1.3 to 1.8 W/m²K – compared with 2.5 to 3.0 in the unrefurbished state.
The fabric cannot be replaced. Profiled frames, historic fittings, hand-crafted glazing bars – a replica costs €1,800 to €3,500 per window and is rarely as good.
New windows make the building more airtight. The air exchange through leaky box-type windows disappears. Without changed ventilation habits, mould develops – the most common consequential damage after replacing windows in a period building.

For well-preserved box-type windows in protection zones, refurbishment is almost always the better decision: permitted, preserves the fabric, superior in sound insulation. In terms of thermal insulation, new installation comes out ahead. This trade-off has to be made on site, not from a catalogue.

The installation decides, not the window

The relevant standard is ÖNORM B 5320. The rule behind it is: tighter on the inside than on the outside.

1 · Airtight on the insideVapour barrier membrane or sealing tape without interruption around the frame. This layer prevents moist indoor air from drawing into the joint and condensing there.

2 · Insulating in the middleThe joint between frame and masonry is insulated – not with expanding foam alone, which is neither airtight nor durable.

3 · Driving-rain-tight and vapour-permeable on the outsidePre-compressed sealing tape. It keeps out rain but allows moisture to escape from the joint to the outside.

4 · Reveal insulated2 to 4 cm on the inside, €28 to €65 per linear metre on the outside with facade insulation. Without reveal insulation the thermal bridge remains and the internal corner develops mould in winter.

5 · Window sills with proper junctionsOutside with side end caps and a slope, inside tight against the frame. A poorly connected exterior window sill channels water straight into the joint.

6 · Plaster stop beadThe transition from plaster to frame moves. Without a plaster stop bead with sealing tape, it cracks open within a year.

The most common misconception: expanding foam is not a sealing system. It fills the joint and insulates, but it is neither airtight nor UV-resistant nor durable. An installation consisting only of expanding foam does not meet ÖNORM B 5320 – and that is exactly how you recognise an offer that is too cheap.

What must be observed with the authorities in Vienna

Protection zone: MA 19 assesses every change to the elevation. Glazing bars, profile width, colour and material are checked. PVC is regularly not permitted on street facades.
Listed building protection: the Federal Monuments Office also decides. Refurbishing the existing windows is then usually the only option.
Courtyard facade: considerably more is possible than on the street side – a common solution is to replace on the courtyard side and refurbish on the street side.
Condominium ownership: windows are generally a common part of the property. Replacing windows in individual flats requires a resolution, otherwise the facade looks inconsistent.
Duration of the procedure: two to four months for clarification in protection zones. This belongs at the start of planning, not at the end.

The eight most common mistakes when replacing windows

Installed with expanding foam only. No airtight interior junction, moisture condenses in the joint.
Reveal not insulated. The thermal bridge remains, mould appears at the internal corner in the first winter.
Ventilation habits not adapted. The building is more airtight, the moisture stays inside.
Exterior window sill without side junction. Water runs into the joint and into the wall.
Saving on the plaster stop bead. The transition cracks open within a year.
Box-type windows disposed of without being checked. Fabric lost that cannot be restored – and possibly not permitted in a protection zone.
MA 19 not consulted. Removal at your own expense, plus proceedings.
Windows installed before the facade insulation. Then the fresh facade has to be opened up again – both belong in one go.

How to check a window offer

Which U-value, for the whole window?Not just for the glass. Uw applies to frame and glass together and is the value that counts.

Is installation to ÖNORM B 5320 described?With an inner sealing layer, insulation and outer sealing tape – not "professional installation".

Are reveal insulation and plaster stop beads included?With linear metres. This is where offers differ the most.

Which window sills, with which junction?Itemised separately for inside and outside.

Is disposal of the old windows included?€35 to €90 per window, glass and frame separated.

Who does the painting at the reveal?This is needed after installation. If the item is missing, you do it yourself or pay extra.

Has the protection zone been clarified?An offer for PVC windows on a protection zone facade is worthless.

Which warranty, on what?Three years on the workmanship under § 933 ABGB, the manufacturer's warranty on the product separately.

When you do not need us

If only a single window sticks or the seal is porous, a window fitter is enough – a construction company is one level too many for that. If you want to insulate the facade anyway, the window replacement belongs there: the scaffolding is up, the reveals are being worked on, and only then can the junction be solved cleanly.

And if your windows face the street in a protection zone, first clarify with MA 19 what is permitted – that costs nothing and saves you an offer that will never be implemented.

Complete supply and installation: what a complete offer for window replacement should include

Many households wanting to replace their windows look for a provider who handles complete supply and installation – and then find that "complete" is interpreted very differently. For one, the job ends when the frame has been foamed in; for another, the reveal, window sill and painting are included. What counts for you is the result: an airtight window in a finished wall.

A complete package has a clear sequence. First the measurement on site, during which the masonry, roller shutter box and junction situation are also recorded. Then the order from the manufacturer according to these dimensions, delivery into the flat, removal and disposal of the old windows, installation with an airtight junction on the inside and a driving-rain-tight one on the outside, followed by plastering in, reveal, window sills and painting. Only when all this is done is the room habitable again.

Why this bundling makes sense: every interface between two firms is a point where nobody is responsible. If condensation forms on the reveal, the fitter says it is due to the plaster and the painter points to the installation. With one contractor for all steps, this discussion does not happen. If the walls are to be freshened up afterwards as well, you will find the right services on the painting work page.

Renovating doors instead of replacing them: new fittings, adjustment, painting

Not every door that sticks or has become unsightly has to go. In Viennese period buildings in particular, the original panelled doors and double doors are often more solid than any catalogue door today. A door renovation starts with the question of what actually bothers you. If the door scrapes on the floor, the frame has usually settled or a hinge is worn – this can be readjusted. If it closes poorly, replacing the fittings with a new lock, new handle set and matching strike plate often helps.

Visually, painting makes the biggest difference. Several old layers of oil paint are stripped or sanded, cracks are filled and the surface is repainted. The costs depend almost entirely on the substrate: a smooth, well-preserved door is done quickly, one with five layers of paint and mouldings takes considerably longer. For comparison: according to the prices above, a new interior door including frame and installation costs €480 to €1,200 net. If the renovation stays below that and the fabric is good, it is the better choice. For flat entrance doors with fire or sound protection requirements, however, renovation is rarely enough.

Windows in detached and terraced houses on the outskirts

In Liesing in the 23rd district (1230) and in other outer districts there are many detached and terraced houses from the 1960s to the 1980s. The questions there are different from those in a Gründerzeit building. There are no box-type windows, but coupled or early insulated glass windows, often with roller shutter boxes that are barely insulated. Here window replacement brings the most benefit if the box is insulated at the same time and the junction with the external wall is carried out cleanly. If facade insulation is planned, the new windows should move outwards into the insulation layer – which is why it pays to plan both together with the facade insulation.

Frequently asked questions about windows and doors in Vienna

What does a window replacement cost per window?

€750 to €1,800 including removal, installation and plastering in. PVC €750–1,100, timber €950–1,500, timber-aluminium €1,200–1,800. Reveal insulation, window sills and disposal come on top.

What does it cost to replace all the windows in a flat?

For eight windows and a balcony door in timber-aluminium, around €21,000 net including all junction work. Of this, about €7,400 is for reveals, window sills, roller shutter boxes, disposal and painting.

Why are some quotes so much cheaper?

Usually the junction work is missing: reveal insulation, plaster stop beads, window sills, disposal, painting. With eight windows that quickly adds up to €7,000. Do not compare the window price, compare the list of items.

What is the Uw value?

The thermal transmittance of the entire window, frame and glass together. That is what counts, not the Ug value of the glass alone. Modern windows achieve 0.8 to 1.1 W/m²K, a refurbished box-type window 1.3 to 1.8, an unrefurbished one 2.5 to 3.0.

Is triple glazing worthwhile?

In new builds and well-insulated buildings, yes. In an uninsulated period building, the step from double to triple glazing brings less than expected, because the surrounding wall remains the bigger heat-loss path. In addition, triple glazing is heavier, which can be relevant with old frame structures.

Should I replace or refurbish my box-type window?

In protection zones and if well preserved, usually refurbish: €900 to €2,200 per window, always permitted by the authorities, preserves the fabric and is often better for sound insulation than a new window. In terms of thermal insulation, replacement comes out ahead.

What happens when a box-type window is refurbished?

Remove the sashes, strip old layers of paint, repair damaged timber or renew it piece by piece, free up the fittings, mill in a continuous seal, repaint, adjust. On request, a low-e pane is fitted in the inner sash.

Is the sound insulation better after replacement?

Not automatically. A box-type window with two layers and an air gap of 15 to 25 cm often insulates against traffic noise better than a modern single window. If noise is your main problem, say so beforehand – then the glazing is designed accordingly.

Why did mould appear after the windows were replaced?

This is the most common consequential damage in period buildings. Old windows were leaky and ventilated permanently. New ones stop this air exchange, the moisture stays in the room and condenses at the coldest spot – usually the window reveal if it has not been insulated.

How should I ventilate after the replacement?

Three to four times a day, air thoroughly for five to ten minutes, for less time in winter. Tilted windows are the mistake: they cool down the reveal without exchanging the air effectively – and that is exactly where the mould then appears.

Do the reveals have to be insulated?

Yes, without fail. Without reveal insulation the thermal bridge remains, and mould forms at the internal corner of the window in winter. €28 to €65 per linear metre – this is not an item to save on but the precondition for the replacement to work.

What is ÖNORM B 5320?

The standard for connecting windows and doors to the masonry. The principle: airtight on the inside, insulating in the middle, driving-rain-tight and vapour-permeable on the outside. Anyone who only uses expanding foam does not meet it.

Isn't expanding foam enough?

No. It fills and insulates, but is neither airtight nor UV-resistant nor durable. Moist indoor air passes through it and condenses in the joint. An installation without an inner sealing layer is the classic defect in offers that are too cheap.

Windows and doors: do I need a permit?

If the external appearance changes in protection zones, yes, via MA 19, and for listed properties additionally via the Federal Monuments Office. Clarification takes two to four months. More is usually possible on the courtyard side than on the street side.

Are PVC windows allowed in a protection zone?

Regularly not on street facades. Glazing bars, profile width, colour and material are assessed. Timber or timber-aluminium with matching glazing bars has a much better chance; more is possible on the courtyard side.

Windows and doors: who decides in a condominium?

Windows are generally a common part of the property. Replacing windows in individual flats requires a resolution of the owners' meeting – otherwise the facade looks inconsistent, and in the event of a dispute removal can be demanded.

Windows and doors: who pays in a rented building?

Maintaining the windows is basically the landlord's responsibility under § 3 MRG if they are defective. Replacing functioning windows as an improvement falls under § 4 MRG and is to be financed from the rent reserve.

Are there subsidies for windows?

As part of a thermal refurbishment, yes: THEWOSAN from the City of Vienna with proof via the energy performance certificate, and proportionally via wohnfonds_wien as part of a basic refurbishment. The application must be approved before the contract is awarded.

How long does the replacement take?

One to two windows per fitting team per day including junction work. For eight windows and a balcony door, expect four to six working days, plus painting work on the reveals.

How long is the flat open?

A few hours per window – removal and installation take place on the same day. No window stays open overnight. In rain or frost the work is done in sections.

Can windows be replaced in winter?

Yes, the installation itself depends little on the weather. Plastering in and painting require temperatures above 5 °C, which may be postponed until spring. We tell you this beforehand instead of promising a date that only holds in ideal weather.

What happens to the old windows?

Separate disposal of glass and frame with a certificate, €35 to €90 per window. On request, well-preserved historic box-type windows can be stored or passed on instead of going into the skip.

Do you also do interior doors?

Yes, €480 to €1,200 per door leaf including frame and installation. In drywall partitions the frame needs a UA profile for stiffening, otherwise a crack appears above the lintel. Soundproof doors with 32 to 42 dB and classified fire doors as well.

Can historic double doors be preserved?

Usually yes, and it is worth it: strip, repair, free up the fittings, repaint. Old Viennese double doors with panels and brass fittings are fabric that no catalogue door can replace.

Do you install front doors with a security class?

Yes, €2,200 to €6,500 depending on the resistance class and design. The anchoring in the masonry is what matters – the best door is of little use if the frame is only foamed in.

Windows and doors: who carries out the work?

Removal, installation, plastering in, reveal insulation and painting are done by our own people. The windows themselves come from manufacturers we have worked with for years; the product details are stated in the offer.

Can I buy the windows myself?

Yes, then the offer states "material supplied by client". Exact measurements and junction dimensions are important – incorrectly ordered windows cannot be returned. We supply the list of dimensions so that nothing goes wrong when ordering.

Windows and doors: is there a fixed price?

Yes, after measurement, as a bill of quantities with numbers of units, Uw values, a description of the junction to ÖNORM B 5320, linear metres for reveals and window sills, and explicit exclusions.

Windows and doors: how quickly will I get an offer?

Measurement within five working days throughout Vienna, offer within two working days after that. For properties in protection zones there is also the clarification with MA 19, which can take two to four months.

What is included in a window replacement with complete supply and installation?

Measurement, ordering, delivery into the rooms, removal and disposal of the old windows, installation with an airtight junction on the inside and a driving-rain-tight one on the outside, then plastering in, reveal, window sills and painting. If one of these steps is missing from the offer, you have to organise it yourself later – and then it is often unclear who is responsible for defects.

Is it worth replacing the fittings on old windows and doors?

Often yes, if the frames and sashes are in good condition. New fittings, seals and careful adjustment cure sticking, draughts and poor closing. For box-type windows this is part of a refurbishment, for interior doors often the cheapest solution. If the timber or frame is rotten, even the best fittings will not help.

Can historic interior doors be restored instead of buying new ones?

Yes, and in period buildings this is often the better solution. The door is stripped or sanded, cracks are filled, hinges readjusted and fittings renewed, then it is repainted. Solid timber panelled doors are preserved this way. Whether the effort is worthwhile is shown by a site visit, because the number of old paint layers determines the effort.
