Steel Door Replacement: Renew the Existing Door, or Replace It?
Not every problem calls for a new door. When is recladding or a part swap enough — and when does the whole door have to go?

The short answer to this question: yes — but not on every line item. Seven or eight items make up a villa door's cost, and only three of them directly determine security. The rest is about appearance. Cut in the right places and you lose nothing in security; cut in the wrong ones and the door becomes a panel that merely looks like a door.
Body sheet. A door's strength comes from the sheet thickness of the leaf and the frame. Ours are built with a 2 mm DKP sheet omega-formed frame and a 1.5 + 1.5 mm double-sheet leaf; total leaf thickness is 90 mm. There are doors on the market made from a single 0.8 mm sheet — that's where the price difference comes from. You can feel the gap just by pressing with your hand.
The lock. A door's weakest point is usually the lock, not the body. Italian Mottura or Mul-T-Lock cylinders offer markedly higher resistance to copying and drilling. The lock is a small slice of the total cost — cutting it makes no sense.
Reinforcement zones. Unless the areas around the lock and hinges are separately strengthened, sheet thickness alone isn't enough. In our doors these zones are backed with 3 mm steel. Since it's invisible from the outside, it's the first item to get dropped — yet under forcing, it's the first place to give way.

| Item | Effect on security | Verdict |
|---|---|---|
| Frame and leaf sheet thickness | Directly decisive | Don't cut |
| Lock cylinder | Directly decisive | Don't cut |
| Lock / hinge reinforcement | Directly decisive | Don't cut |
| Infill (rock wool) | Insulation — indirect | Shouldn't be cut |
| Cladding type | None | Cut freely |
| Glass and transom window | Glassless is more secure | Cut freely |
| Wrought iron / carving | None | Cut freely |
| Automation | None (mechanical lock remains) | Can wait |
Infill isn't a security item, but we don't recommend cutting it. 80 kg/m³ rock wool provides both sound and heat insulation, and it changes how the leaf feels. Knock on a leaf that's empty or filled with low-density material and it gives a tinny sound — which undermines the sense of security too.
Most of it comes from sheet thickness, the lock system and the reinforcement zones. Cladding and decorative items push the price up but add nothing to security.
Yes. A solid leaf with no glazed section carries fewer weak points against forcing. If you do want glass, 5+5 mm laminated glass is the way to go.
Card and keypad access systems can be added afterwards. If the door is built with that in mind, the cable routing is prepared from the start, making the later retrofit easy.
At the site survey we break out what each item costs, line by line — so you decide where to trim with the numbers in front of you. Call 0532 689 21 46 or send a photo of your entrance via WhatsApp.
You can ask about your own door, your measurements or your specific area. Our production team reads these and answers here. If you'd like a faster reply, you can message us on WhatsApp.

Clear trends are shaping villa entrances in 2026: wider leaves, surfaces that blend into the facade, hidden frames, and a growing appetite for natural texture.

Anything left out of a villa door contract becomes a point of dispute. The clauses to require for measurement responsibility, delivery time, warranty scope and whether installation is included.
