Which techniques do we use in facade renovation?
Protector specialises in all modern and traditional facade techniques.
1. Facade cleaning
Depending on the condition and type of brick, we choose the right method:
- Steam cleaning
- Nebulisation
- Chemical cleaning
- Sandblasting
- Soft blasting with lime granules (for historic facades)
Each cleaning is followed by an evaluation of the brick quality.
2. Repairing joints (repointing)
Joints account for 25–30% of your facade’s protection. Worn joints can allow water to enter.
We provide:
- Removal of old joints
- Cleaning of the masonry
- Repointing with mortar in the correct colour and hardness
- Inspection of underlying masonry
3. Crack repair
Cracks are not only treated cosmetically; we also repair the cause. Possible techniques:
- Injection
- Installing spiral anchors
- Stabilising masonry
- Rebuilding damaged bricks
4. Hydrofuge (water-repellent treatment)
A transparent protective layer against:
- Rain impact
- Dirt
- Moss growth
- Moisture penetration
The hydrofuge remains effective for 10–15 years.
5. Facade insulation
Energy-efficient renovation is increasingly important. Protector integrates:
- Insulation panels
- Exterior plaster
- Finishing in decorative plaster, limewash or brick slips
Can lead to a saving of 10% on your energy bill
6. Whitewashing & painting
Traditional whitewash or modern facade coating:
- Levels surfaces
- Hides old joints
- Provides a modern appearance
- Protects bricks from moisture
7. Restoration of ornaments
Protector is strong in restorations, including:
- Cornices
- Brackets
- Ornaments
- Decorative moldings
- Historic lime plaster

Answers to frequently asked questions about facade renovation
How long does a facade renovation take?
A facade renovation typically takes 2 to 10 working days, depending on the chosen techniques, the condition of your facade and accessibility. Small interventions such as cleaning or hydrofuge are often completed within a few days. For more extensive renovations, including repointing, crack repair, insulation or whitewashing, the execution time is longer. Location also matters: a terraced house in a city street requires more preparation than a detached house. After inspection, you always receive a clear schedule so you know exactly when work starts and how the process unfolds.
What is the average cost of facade renovation?
The cost of facade renovation depends on the area, condition of your facade, and chosen technique. During inspection, you receive a detailed quote with transparent pricing, including materials, labour and possible options. This way you know exactly what you are paying for and which choices affect the total cost.
When is facade renovation necessary?
Facade renovation becomes necessary when your facade shows signs such as cracks, porous bricks, loose joints, moss growth, black stains, damp spots or peeling paint. These problems are not only aesthetic: they can also lead to structural damage or moisture penetration. The sooner you act, the smaller the risk of expensive repairs. During a free and non-binding analysis, our specialists assess the state of your facade and advise on the best solution.
Does facade renovation help with moisture problems?
Yes. Many moisture problems arise from damaged joints, porous masonry, or a facade that has lost its water-repellent function. Renovating your facade prevents penetrating damp, mould, salt efflorescence and interior wall damage. During inspection, we first determine the exact cause—rising damp, condensation or infiltration—so we can propose an effective and definitive solution. A hydrofuge treatment is often part of the renovation plan.
Is a permit required for facade renovation?
For most facade work, a standard building permit is not required, though a notification obligation may sometimes apply. This is mainly for whitewashing, painting, insulation or when the appearance of your house changes. For protected or historic facades, specific rules apply. Protector checks in advance which steps you need to take and ensures your renovation complies with all legal requirements.
Does facade renovation improve my home's energy efficiency?
Yes. Especially when you choose exterior wall insulation. Exterior insulation eliminates thermal bridges and keeps heat inside, providing more comfort and lower energy bills. Depending on the insulation thickness, consumption can drop by 15%. Whitewashing and hydrofuge also improve wall moisture balance, indirectly benefiting energy performance.
