Comparing quotes via a platform such as jeofferte.nl can provide insight into different approaches and price levels.

1. Cleaning the facade

Why clean?
Due to air pollution, rain and biological deposits (algae, moss), a facade will become dirty over time. Cleaning is usually the first step in facade maintenance and facade renovation, and is often necessary before repair work (such as grouting or impregnation) can be carried out.

Methods and costs

Steam cleaning

• Application: light soiling, sensitive facades
• Method: warm water/steam under low pressure
• Costs: € 5 – € 10 per m²

High-pressure cleaning

• Application: normal soiling, sturdy facades
• Method: water under higher pressure
• Costs: € 8 – € 15 per m²

Sandblasting or wet blasting

• Application: stubborn dirt, moss, graffiti
• Method: mixture of water, air and abrasive under pressure
• Costs: € 12 – € 22 per m²

Chemical cleaning

• Application: heavy pollution, soot, paint, stubborn deposits
• Method: special cleaning agents are applied and rinsed off
• Costs: € 15 – € 20 per m²

Mist blasting (monuments)

• Application: monuments or very vulnerable facades
• Method: gentle blasting technique, low pressure
• Costs: € 25 – € 45 per m²

2. Jointing

Why renew joints?
Joints seal the space between stones and prevent moisture and dirt from entering. Poor jointing can lead to moisture problems, mold and structural damage. During renovation, old joints are ground out and re- jointed.

Types of jointing and costs

Local repair of joints

• Method: Chisel out and fill loose joints
• Costs: € 7 – € 11 per m²

Complete grinding and re-jointing

• Flat joint: € 30 – € 40 per m²
• Recessed joint: € 35 – € 45 per m²
• Tuck or cut joints (traditional): € 60 – € 100 per m²
  (Often used in historical buildings and gives a luxurious appearance.)

3. Impregnation

Why impregnate?
After cleaning and possibly re-pointing, the facade is often impregnated. This involves applying an invisible, water-repellent layer that ensures that moisture and dirt do not penetrate the facade. This extends the lifespan and reduces the frequency of future maintenance.

Costs

• Impregnation only: € 6.50 – € 10 per m²
• Cleaning + impregnation as a combined project: € 20 – € 30 per m²
  Impregnation lasts an average of ten years and can prevent many moisture problems.

4. Repair of damage to masonry

Why repair damage?
Damaged stones, cracks or loose masonry must be repaired to keep the facade safe and watertight.

Typical costs

• Replacing loose stones: € 10 – € 25 per stone (depending on the quantity and type of stone)
• Repairing cracks: From € 100 per crack (depending on the length and required repair technique)

5. Other activities

In addition to the aforementioned activities, there may be additional costs:

• Scaffolding: for larger projects 500 – 1,000 euros extra
• Aerial platform: alternative to scaffolding for well accessible facades
• Restoration work for monuments: highly variable, often custom-made from 75 euros per m²
• Exterior wall insulation: 100 – 150 euros per m² (permit required)

Example calculation facade renovation 100 m²

For an average corner house with 100 m² facade:

1. Steam cleaning: 100 × 15 euro = 1,500 euro
2. Complete grinding and grouting: 100 × 35 euro = 3,500 euro
3. Impregnation: 100 × 10 euro = 1,000 euro

Total indicative price: approximately 6,000 euros (including VAT, labor and material)

Any additional costs for crack repair and scaffolding will be added.

Factors that influence these prices

1. Surface area of the facade – larger projects often result in a lower price per m²
2. Accessibility – difficult to access facades require scaffolding or aerial platforms
3. Degree of pollution and damage – light pollution is cheaper than heavy deposits
4. Material of the facade – some materials require a gentler, more expensive approach
5. Experience and specialization of the professional – recognized companies are slightly more expensive but deliver safer and more sustainable work

Conclusion

The costs for facade maintenance and facade renovation in 2025 range from a few hundred euros for minor maintenance to tens of thousands of euros for major, complete renovations of monumental buildings.

What is joint work and why is it so important?

A facade usually consists of brickwork (bricks, natural stone or other stony materials). The openings between these stones are filled with joint mortar. This is called joint work. The joint work has several important functions:

1. Protective function
   Joints ensure that water, moisture and dirt cannot get between the stones. If the joint work is poor, rainwater can penetrate and expand in the winter due to frost. This leads to cracks in stones, loosening pieces and ultimately structural damage.
2. Constructive function
   Joint work holds the stones together and contributes to the stability of the wall.
3. Insulating function
   Good joints limit heat loss and prevent drafts through small cracks.
4. Aesthetic function
   The type of joint largely determines the appearance of a facade. Tight joints give a modern look, while clipped or cut joints provide a luxurious and classic finish.

Due to weather influences and age, joints wear slowly. After some time they must be repaired or completely replaced.

Types of work on joint work

There are roughly two categories:

1. Local joint repair
• Application: Only small pieces of joints that come loose or are damaged are replaced.
• Suitable if the majority of the facade is still in good condition.
2. Complete grinding and re-grouting
• Application: All old joints are removed. Then the facade is re-grouted.
• Necessary if a large part of the joints is porous, cracked or fallen out.
• This is labor-intensive, but ensures a facade that looks like new again and is structurally strong.

Cost per m² for jointing (indication 2025)

1. Repairing local jointing

• Average price: € 7 – € 11 per m²
• Only suitable for minor damage.

2. Complete grinding and re-jointing
With a complete renovation, the joints are removed with a grinder or chisel, the facade is cleaned, and then new jointing is applied.

Cost per type of joint:

• Flat joint: € 30 – € 40 per m²
  Most common form, where the joint is flush with the brickwork.
• Recessed joint: € 35 – € 45 per m²
  The joint is slightly recessed from the stone surface and provides more shadow effect.
• Flush or cut joints: € 60 – € 100 per m²
  Traditional jointing where the joints are carefully finished.
  This is mainly used for monumental and classic buildings.
  Very labor-intensive and therefore much more expensive.

Factors that influence the price of jointing

1. Accessibility
   Higher buildings require scaffolding or aerial platforms, which incur extra costs.
2. Condition of the facade
   The worse the jointing and brickwork, the more work is needed.
3. Type of joint
   Tuckpointing and flush pointing are specialized and time-consuming, which increases costs.
4. Surface area
   The larger the project, the lower the price per m² due to efficiency.
5. Combination with other work
   Jointing is often combined with cleaning and impregnation. By having this done in one project, costs are saved.

Procedure for complete joint renewal (step-by-step plan)

1. Inspection
   The facade is fully inspected to determine which parts need to be repaired and whether the stones themselves are still good.
2. Removing the old joints
   The old joints are removed by grinding or chiseling. Approximately 1.5 to 2 cm of the joint is removed.
3. Cleaning the facade
   The masonry is cleaned to ensure good adhesion of the new joint mortar. This is often done with water or steam, sometimes with special brushes.

Example calculation for a corner house of 100 m² (flush joints)

• Complete grinding and jointing: 100 m² × € 35 = € 3,500
• Possible combination with cleaning and impregnation: approximately € 6,000 total for the entire process.

Conclusion

Renewing the jointing is a specialist and labor-intensive job, but the result is a facade that looks like new again and is technically in top condition.

• For small repairs: 7 – 11 euros per m²
• For complete renewal: 30 – 100 euros per m² depending on the type of joint

By comparing multiple quotes via for example a platform such as jeofferte.nl, you can find the right specialist and save costs.

3. Degree of pollution: The heavier the pollution, the more expensive the method.
4. Type of facade material: Soft materials require more expensive and careful techniques.
5. Combinations: Cleaning in combination with jointing and impregnation is often more advantageous.

Conclusion

The costs for facade cleaning in 2025 are between approximately 5 and 20 euros per m² for standard methods and can amount to 45 euros per m² for specialist techniques such as mist blasting. For larger projects and when cleaning is combined with jointing and impregnation, the total costs per m² are lower.

Comparing multiple quotes via a specialized platform such as jeofferte.nl helps to get a good idea of the best method and the costs.

1. Combine multiple jobs in one project

Combining cleaning, jointing and impregnation in one go results in significant savings:

• You only pay once for scaffolding or aerial platforms.
• The activities are efficiently coordinated.
• The price per m² is lower because the specialist can carry out the work in one planning.

2. Request multiple quotes and compare carefully

Requesting multiple quotes from different facade specialists is one of the most important ways to save money.
What to look out for:

• Don't just look at the lowest price, but also at the method, guarantee and experience.
• Platforms such as jeofferte.nl make it easy to compare multiple companies and gain transparency in the working method and costs.

3. Plan the work outside the peak season

Facade specialists are busiest in the spring and autumn period, which can lead to higher prices.
In quiet periods, such as summer or winter (in dry and suitable weather), there is often more room for discounts and favorable planning.

4. Avoid high costs through regular inspection

Regular inspection of the facade (once every 3 to 5 years) ensures that minor defects, such as cracks or loose joints, are addressed in a timely manner.

• Early action prevents major renovations.
• Minor maintenance is much cheaper than complete restoration projects.

5. Perform periodic visual inspection yourself

By walking around your building yourself several times a year, you can identify emerging problems in a timely manner:

• Loose or crumbling joints
• Cracks in the brickwork
• Moss or green deposit low to the ground
  By reacting quickly, a small repair may suffice.

6. Choose the right method, not the cheapest

Cleaning cheaply with the wrong method can lead to damage to joints and stones. In the long term, this means higher costs.

• Always ask for a sample: a small piece of facade is treated first so that you can assess the result.
• A specialist chooses the right technique based on material and contamination.

7. Save on accessibility

Depending on the building, the use of a buckle may be cheaper than scaffolding.
Discuss this in advance with the specialist to avoid unnecessary costs.

8. Have the fachada impregnated after cleaning

Impregnating seems like an extra cost item, but provides long-term savings:

• The facade stays clean longer.
• Dirt and moisture penetrate the facade less quickly, reducing the maintenance frequency.

9. Performing Minor Maintenance Yourself

Minor soiling or initial deposits low to the ground can be carefully removed yourself.
Use:

• No high-pressure cleaner (can damage joints)
• No aggressive cleaning agents
• Only soft brushes and suitable cleaning agents

Conclusion

By planning smartly, checking in time, and comparing multiple quotes, the costs for facade maintenance can be significantly reduced. Preventive action prevents small problems from developing into expensive renovations.
A platform like jeofferte.nl helps to quickly compare multiple proposals and thus choose the most cost-efficient solution.

Facade maintenance and facade renovation are indispensable works for the preservation and value of a building. A facade is constantly exposed to weather influences, pollution and mechanical stress. Without regular maintenance, small defects, such as cracks or bad joints, can lead to larger problems such as moisture penetration, mold formation, crumbling stones and even structural damage.

Why timely maintenance is important
Regular maintenance – such as cleaning, repairing joints and impregnation – significantly extends the lifespan of a facade. It not only provides protection against moisture and dirt, but also for a well-maintained appearance. Preventive measures are always more advantageous than catching up on overdue maintenance because major repair work is much more labor-intensive and expensive are.

Costs and price-determining factors
The costs depend on several factors: the condition of the facade, the accessibility, the chosen method and the surface area. For light maintenance you have to account for several thousand euros, while complete renovations for larger homes or monumental buildings can amount to tens of thousands of euros.

Saving without compromising on quality

·       Combine activities in one process.

·       Have the facade inspected periodically and address small defects immediately.

·       Compare multiple quotes, for example via a platform such as jeofferte.nl.

·       Choose the right cleaning method; avoid damage due to improper use.

Future-oriented work
By investing in facade maintenance in a timely manner, you prevent the facade from losing its protective function. A well-maintained facade contributes to comfort, energy efficiency and preservation of the value of the home or commercial building.
