Üsküdar Steel Doors: Survey, Manufacture, Installation

Üsküdar rises from the Bosphorus shoreline up to the Çamlıca hills across 33 neighbourhoods and 514,294 people. Kuzguncuk and Çengelköy keep a streetscape of older, protected houses facing the water; Bulgurlu, Kısıklı and Güzeltepe climb a steep hillside on narrow streets; Altunizade carries a stretch of office buildings alongside its housing. Getting a door up the hill is sometimes a bigger question here than choosing the door itself.

What fails on a steel door, and why

A door usually gets changed because something has failed: the leaf catches on the frame, the bolt misses its keep, noise from the landing carries inside. All three trace back to the installation or to the material. The rows below put the symptom beside what we do about the same item, with the values from the technical table.

What turns up on site
The frame was not built for the opening. Nothing shows in the first months. As the building settles, the leaf starts to catch on the frame and the bolt struggles to find its keep. Most winter calls that begin with "the door will not close" come down to this.
How we handle it
We measure at the address and the frame is built to that opening. Every model in the catalogue is made to measure, so we are not bedding a ready frame into the gap with foam.
What turns up on site
The door skin is thin. Knock on the leaf and it rings hollow, and after a while the area under the handle and the line of the lock flexes inward. The finish then lifts along that flex.
How we handle it
The skin is the same across all four series: 2 mm Ereğli A1 steel door skin. The thickness does not drop on the entry model; the difference stays in the finish and the design.
What turns up on site
The core is sparse, or there is none. Conversation on the landing carries into the home and the hall stays cold in winter. A hollow note instead of a solid one when the door shuts points at the core.
How we handle it
The leaf is filled with 150 kg/m³ rock wool core. The same core does the work for sound and for heat.
What turns up on site
The lock holds at one point only. With the leaf fixed at the lock line alone, force pulls the door away from the frame, and the leaf flexes even where the bolt itself holds.
How we handle it
The lock ties the leaf to the frame at several points: Kale 256G 14-point lock. It is one of the four values that do not change between series.

Üsküdar Steel Door prices

A steel door in Üsküdar starts from $480. The figures do not part on the body: all four series carry 2 mm Ereğli A1 steel, 150 kg/m³ rock wool and Kale 256G lock. The difference sits in the finish, the measurement and the hardware. A net figure follows the on-site survey, in a written quote.

Which choice brings which band
Series	Which choice	What sets the band	Price band
Eko	A first home, a rented apartment	A standard door opening measurement and a deliberately narrow finish palette keep this band at the lower end.	from $480
Plus	A home entrance, visual variety	At the same standard measurement, a wider set of finish, colour and handle options lifts the band.	from $700
Pro	An apartment building communal entrance, a workplace	The mechanism chosen for heavy opening and closing traffic, together with communal area hardware, sets this band.	from $1,160
Ultra	Made-to-measure size, one-off design	Manufacture to a made-to-measure size, with a wide finish and accessory combination, sets the top of the band.	from $1,740

The figures here are starting ranges; they move with the measurement, the surface finish and the hardware you choose. For a net price on your own door, message us on WhatsApp or ask for a free on-site survey.

Every model carries 2 mm Ereğli A1 steel door skin, 150 kg/m³ rock wool, a Kale 256G 14-point lock and TSE EN 1627 certification as standard.

Every model carries the standard warranty; on upper-tier models it runs longer, depending on the material chosen.

The on-site survey and the installation are free within Istanbul. For an address outside Istanbul, please call our customer line.

The items that set the price

Four items move the price: the door frame measurement, the series chosen, the surface finish and hardware, and the work that turns up on site. If the door opening is not a standard one, the frame is made to measure. Taking out an old frame is discussed during the survey, not added afterwards.

Door frame measurement
If the door opening is not a standard one, the frame is made to measure; material and labour follow from that.
Series and model
All four series share the same body, the same insulation and the same lock; the difference sits in the surface finish, the design and the warranty period.
Surface finish and hardware
The type of finish, the colour, the handle and any extra accessory are what move the quote most.
Work that comes up on site
If the old frame has to come out or the measurement needs correcting, it is discussed during the survey and listed as a separate item in the quote.

Üsküdar Steel Door services

Sales and replacement work for Üsküdar sit on separate pages. Beside the model and price pages there are headings for apartment entrance doors, garden entrances, hingeless pivot doors and communal area fire doors. Each page sets out its own measurement, manufacture and installation sequence, so you can go straight to the one you need.

Every model, price and replacement page. If you are not sure which one to open, the selection guide below narrows it down.

What separates the series

The four series run through the same measurement, manufacture and installation sequence. Eko is for a first home or a rented apartment, Plus for home entrances that want a wider surface finish and colour choice, Pro for apartment building communal entrances and workplaces, Ultra for made-to-measure sizes and one-off design. The table sets that difference out row by row.

The price is settled at the on-site survey, by the measurement, the model and the hardware chosen.

Every model carries 2 mm Ereğli A1 steel door skin, 150 kg/m³ rock wool, a Kale 256G 14-point lock and TSE EN 1627 certification as standard.

Every model carries the standard warranty; on upper-tier models it runs longer, depending on the material chosen.

The on-site survey and the installation are free within Istanbul. For an address outside Istanbul, please call our customer line.

Technical specification

All four series stand on the same base: 2 mm Ereğli A1 steel door skin, 150 kg/m³ rock wool core, a Kale 256G 14-point lock and TSE EN 1627, the standard for resistance to forced entry. They do not part company on those four values; the difference stays in the surface finish, the design and the warranty period.

Technical values that are standard across all series in Üsküdar.

Why the street matters as much as the door in Üsküdar

Before we talk about a model, we usually need to talk about how the old leaf comes out and the new one goes in.

Steep, narrow streets on the hillside: In Bulgurlu, Kısıklı and Güzeltepe a van cannot always park where the entrance is. We note the slope and the nearest point a vehicle can stop during the survey, so the leaf is not left waiting in the street on installation day.
A streetscape that faces the water in Kuzguncuk and Çengelköy: A door on these shoreline streets is part of the building's face to the water, not only a security fitting. We settle the finish and the colour against the facade itself rather than working straight through a catalogue.
Older wooden houses along the Bosphorus: Timber-framed houses here were built before today's standard opening sizes, and the wall thickness can vary from one point to another. We build the frame to the opening we actually measure rather than a standard one.

The measurement and the decision both happen at your address, and the same team returns for anything Üsküdar needs after that.

Free survey and installation within Istanbul
The on-site survey and the installation are free within Istanbul.
Written warranty
Every model carries a warranty as standard. On upper-tier models an extended warranty applies, depending on the material chosen.
We re-measure on site before fitting
We do not simply take the measurement you send. Before fitting, our team comes to the address and measures the door opening again; the risk of a wrong measurement sits with us, not with you.
The net price comes in a written quote
We do not quote a net price over the phone. After the survey, what will be done and what it costs is set out item by item in a written quote.

Photographs from the job

These were taken on site once the door was fitted, not in a studio: the floor is unfinished, the protective film is still on the threshold and nothing has been tidied. You can see how the frame meets the wall and where the architrave ends. No place name goes under them, because the address was never recorded.

How to measure the door opening

A tape measure is all the door opening needs. Width from one inner face of the frame across to the other, height from the top of the threshold to the inner face of the frame head, then the wall thickness. Send those three figures and we can say over the phone which model fits your opening.

Four measurements, in order

Measure inside the door frame at three heights
Open the leaf fully, rest the tape against one inner face of the frame and read it off at the opposite inner face. Repeat near the top, at the middle and close to the floor; if the three differ, write down the smallest, because the leaf has to pass through that gap. The height runs from the top of the threshold to the inner face of the frame head.
Keep the architrave edge separate
The architrave is the frame that covers the joint between the door frame and the wall. Measure it from one outer edge to the other. That figure comes out larger than the one inside the frame: in the catalogue, models with an inside measurement of 90 x 200 cm have an architrave edge between 104 x 208 cm and 108 x 210 cm, and the difference is the width of the architrave itself.
Write down the wall thickness
On the side face of the opening, measure from the inner wall surface to the outer wall surface, and leave the architraves out of that figure. The depth of the frame is built to it, so we need it as much as the width and the height.
Tell us how the floor will finish
If parquet or ceramic tile is going in under the threshold, the measurement has to allow for the finished floor. A covering laid afterwards leaves the door catching along the bottom. Where the floor is not ready, we work out the clearance during the survey.

What to send us

Width and height inside the door frame, in centimetres.
Wall thickness, in centimetres.
Which way the door opens: hinges on the right or on the left.
A photograph of the opening if you have one, with the corner of the frame in shot.

Do not round the figures. Write the half centimetre too, because the frame is built to it.

All 163 models in the catalogue are made to measure. Of the 122 models with a listed measurement, 119 carry the same inside figure, so 90 x 200 cm is a common opening; outside it the model stays and the frame changes.

With the figures to hand, answer the first question in the selection guide

Üsküdar Steel Door selection guide

If you are unsure where to begin, start from the question: an apartment door, an apartment entrance door, or a house with a garden? If the door still stands but the lock, hinge or door frame is giving trouble, the replacement pages are right. For a new door, read the models first and prices after.

These four questions come up on the phone more than any others, before the on-site survey is even booked.

Does my door need replacing, or is a repair enough?: If the leaf and the door frame are sound, the trouble usually sits in the lock, the cylinder, a hinge or the strike plate, and those are changed on site. Once the frame has pulled away from the wall, or the leaf has bowed, a repair only buys time. We settle which it is at your address.
Is an apartment door the same thing as an apartment entrance door?: No. An apartment entrance door opens and shuts hundreds of times a day and works alongside a door closer and entry automation. On an apartment door what matters most is sound and heat insulation, together with the lock. The two are separate products and sit in separate price bands.
Can I take the measurement myself and send it to you?: It helps us picture the job, but it cannot stand in for the manufacturing measurement. The frame opening shifts with the plaster on the wall, the threshold level and the direction the door swings, and a wrong figure only shows itself on installation day. The on-site survey is ours to do.
How do I know which series to choose?: Where the door will stand decides the series. The table below maps the situations we meet most often to the page that covers each one.

Neighbourhoods

We cover the whole of Üsküdar district and do not split it by neighbourhood. The list below names every neighbourhood in Üsküdar; we travel to all of them on the same terms. At the measurement appointment the team comes to your address and measures the door opening there; the model decision is made during that same visit.

Üsküdar Steel Doors: frequently asked

Which Üsküdar neighbourhoods do you work in?

All 33, from central neighbourhoods such as Salacak and Ahmediye to the hillside streets of Bulgurlu, Kısıklı and Yavuztürk, and the shoreline streets of Kuzguncuk and Çengelköy.

How do you get a new door up a steep street if a van can't reach the entrance?

We note the slope and the nearest point a vehicle can stop during the survey, including how far the leaf has to be carried by hand. That distance is settled before manufacture, not discovered on installation day, so the door is never left waiting in the street while we work out a plan.

Is there a restriction on what a door can look like in Kuzguncuk or Çengelköy?

The entrance faces the street directly in these neighbourhoods, so we settle the finish and the colour against the building's own facade. If the property is under conservation protection, we recommend checking the relevant permit process before ordering.

Can an older timber house along the Bosphorus take a steel security door?

Yes, but the opening is rarely a standard size. Wall thickness in these houses can vary from point to point, so we take the measurement at several points and build the frame to match rather than fitting a standard one that would leave gaps.

I live abroad and own a flat near Altunizade. Can the whole job run in English?

Yes. We reply to WhatsApp messages in English, a tenant or agent can host the survey on your behalf, and the written quote comes back to you in English before anything is ordered. You only need to arrange the keys for installation day.

What does a steel security door cost in Üsküdar?

$480 to $2,700 across the four series. A custom frame for an older, irregular opening along the shoreline or in a hillside house tends to land in the upper bands; a standard opening elsewhere usually does not.

Do office floors in Altunizade need different hardware from a flat?

Yes. An office entrance opens far more often through the day, so we specify the lock and hinge count for that volume rather than for the lighter use a residential door sees.
