In short: A facade renovation does not have to mean scraping, re-rendering and repainting every ten years. Stone-look facade panels from TerraDecor go over a sound existing wall, weigh a fraction of natural stone, need no wet trades and cost from €140/m² including delivery within Europe – with a 20-year warranty.
Cracked render, flaking paint, a grey plinth splashed with mud, a house that simply looks tired: sooner or later every building needs a facade renovation. The classic answer is scaffolding, new render and paint – and the same job again in a decade. This guide shows how to read the condition of your facade, compares the main renovation options honestly and explains when stone cladding for exterior walls is the smarter, longer-lasting choice.
When does a facade need renovation?
Walk around the house on a dry day and look closely. These are the typical signs that a facade renovation is due:
- Hairline cracks in the render – common on older houses; they let water in and grow with every frost.
- Flaking or chalking paint – rub your hand over the wall; white powder means the coating is breaking down.
- Hollow-sounding render – tap with a knuckle or a wooden handle; a dull, hollow sound means the render has detached.
- Dark or green patches – algae and moss on north sides and behind shrubs, or damp marks near the ground.
- A battered plinth – the bottom 50 cm takes splash water, de-icing salt, lawnmowers and bicycles.
- An outdated look – sometimes nothing is broken, but the building no longer matches its value or the street.
First fix the cause, then the surface
Wide or stepped cracks, rising damp or salt bloom are symptoms of structural or moisture problems. Have them assessed by a builder or structural engineer first. Any cladding – ours included – needs a stable, solid, dry and clean surface to last.
Facade renovation options compared
There are five common ways to renovate an old facade. Each solves different problems; the table compares them in general terms, not specific products.
| Option | What it solves | Weight on the wall | Site disruption | Look and upkeep |
|---|---|---|---|---|
| Repainting | Faded colour | None | Low | Flat; repeat every few years |
| New render | Cracked, hollow render | Moderate | Wet trades, drying time | Flat; repainting cycles continue |
| External insulation with render | Energy loss | Moderate | High, weeks of work | Flat; render can crack and grow algae |
| Natural stone cladding | Look, protection | Very heavy, often needs a load check and anchoring | High, slow wet installation | Authentic, but can absorb water and crack |
| TerraDecor stone-look panels | Look, protection, plinth damage | Lightweight | Low, glued or screwed, no wet trades | Deep 3D relief; no repainting |
The options can be combined. Many owners insulate first and then finish selected areas – plinth, entrance, gable – with stone cladding, or clad only the parts of the facade that suffer most.
Why stone-look panels suit renovation projects
Renovation means working with what is already there: old masonry, existing render, limited budgets, people living in the house. That is exactly where lightweight panels have an advantage.
- Low weight on old walls. No need to reinforce foundations or add heavy anchoring as with natural stone.
- Fast and clean. No mortar, no grouting, no weeks of drying – the house stays usable.
- No repainting cycle. Hand-coloured, UV-resistant surfaces do not chalk or fade like paint.
- Real relief, not a print. Depth from a few centimetres up to 50 cm casts natural shadows that change through the day.
- Invisible joints. No grout lines and no repeating pattern give away that the stone is made, not quarried.
- Tough plinth protection. Water-, frost-, impact- and acid-resistant – ideal for the zone that suffers most.
Which parts of the facade to clad?
You do not have to clad the whole house to transform it. Typical areas, from small budget to full makeover:
- Plinth – the lowest 40–80 cm. Protects the most damaged zone and visually "grounds" the house.
- Entrance wall – the first impression for every visitor, often combined with a canopy or house number.
- Garage front or carport wall – large, simple surfaces that change the street view.
- Gable or one feature wall – a strong architectural accent while the rest stays rendered.
- Complete facade – for a radical new character, from a light limestone villa to a dark slate house.
Which stone look suits which house?
A facade renovation is the chance to give a building a character that fits its architecture and region:
- Mediterranean villa or bright modern house – pale limestone or warm sandstone, ideally with light paving.
- Alpine or rural house – grey granite or layered slate, combined with wood.
- Cubic modern architecture – dark basalt or black slate as a calm, monolithic surface.
- Post-war or 1970s house – a stone plinth and entrance alone often modernise the whole building.
Shallow relief keeps narrow streets calm; deeper relief needs a few metres of distance to unfold its shadows.
Facade renovation with stone-look panels, step by step
- Assess and repair. Remove loose render, repair cracks, solve damp problems. The base must be stable, solid, dry and clean.
- Measure and photograph. Send us the wall dimensions and photos of each side; mark windows, doors and downpipes.
- Choose the stone and relief. Pick a design from the catalogue or send a photo of the stone you like.
- Written offer and production. Production starts after you accept and pay the advance; you approve photos of the finished panels before shipping.
- Installation. Your installer glues the panels with a suitable mounting adhesive or screws them; screw heads disappear under caps in the same colour and texture.
- Edges and details. Window reveals, corners and the transition to render are planned in advance so the stone looks continuous.
From the workshop: Every facade panel is handmade and hand-coloured in Serbia, so no two modules are identical and the wall never shows a repeating pattern. Behind it is our patented technology – no one else in the world produces rock and stone imitations this way – and more than 20 years of experience since Aquadecor started in 2004.
What does a facade renovation with stone cladding cost?
Facade panels cost €140/m² for relief up to 5 cm, plus €50/m² for every additional 5 cm. Prices exclude VAT, delivery within Europe is included, and the final price is confirmed in a written offer. Installation is done by your own installer, so labour depends on your region.
| Renovation area (example) | Area and relief | Panels (excl. VAT) |
|---|---|---|
| Plinth of a detached house, 40 m × 0.6 m | 24 m², up to 5 cm | €3,360 |
| Entrance wall | 12 m², 10 cm | €2,280 |
| Garage front | 18 m², up to 5 cm | €2,520 |
| Gable feature wall | 35 m², 10 cm | €6,650 |
| Complete facade of a small house | 120 m², up to 5 cm | €16,800 |
When you compare offers, look beyond the price per m². A painted facade needs scaffolding and new paint again after some years; natural stone adds structural work and slow installation. A cladding without repainting cycles and with a 20-year warranty usually costs less over the life of the building.
Permits, listed buildings and neighbours
Changing the appearance of a facade can require notification or a permit, depending on your country and municipality. Listed buildings, conservation areas and apartment owners' associations usually have their own rules. Check this before ordering – with a written offer and visualizations you have good documents for the application.
FAQ
Can the panels be installed over existing render?
Yes, if the render is sound, firmly bonded, dry and clean. Hollow or crumbling render must be removed and repaired first.
Do the panels insulate the house?
They are a decorative, protective finish, not an insulation layer. If you plan external insulation, do it first and plan the fixing of the panels together with your facade contractor.
How do I clean a stone-look facade?
With ordinary household cleaners – even hydrochloric acid can be used, which would etch real limestone or marble. Mild abrasive cleaners are fine; avoid wire brushes, knives and solvents.
What does the warranty cover?
20 years (up to lifetime on selected products). Not covered: mishandling, improper installation, sharp-object damage, aggressive chemicals or solvents and modifications.
