How much does it cost to wash a brick house? 🧱💧
Washing a brick house is often discussed in terms of appearance, maintenance, and long-term care of masonry. One of the most common questions around this subject is cost. The price of washing a brick house can vary widely depending on several factors, including size, height, condition, method used, and local labour rates. Understanding how these elements interact helps explain why prices differ so much from one property to another.
What is meant by washing a brick house?
Washing a brick house usually refers to the process of removing surface dirt, algae, moss, pollution staining, and general grime from brickwork. This is not structural repair or repainting. The work typically targets:
- External brick walls
- Mortar joints (surface cleaning only)
- Decorative brick features
- Occasionally soffit-level brickwork
The price reflects labour, equipment, access requirements, and the overall scale of the job rather than just the time spent spraying water.
Average cost to wash a brick house in the UK
Across the UK, the typical cost range for washing a brick house sits between £400 and £1,500, depending on the circumstances. Smaller properties fall near the lower end, while large or complex buildings can exceed this range.
Typical price ranges by property type
| Property type | Approximate cost range |
|---|---|
| Small terraced house | £400 – £650 |
| Standard semi-detached house | £600 – £900 |
| Detached house (2 storey) | £800 – £1,200 |
| Large detached house | £1,200 – £1,500+ |
These figures assume full external brickwork cleaning and average accessibility.
Cost per square metre
Some pricing models are based on surface area rather than property type. Brick washing costs are often calculated between £5 and £12 per square metre.
| Brick surface area | Estimated cost |
|---|---|
| 80 m² | £400 – £960 |
| 120 m² | £600 – £1,440 |
| 160 m² | £800 – £1,920 |
This approach is often used when buildings do not fit standard residential categories.
Factors that influence the cost 📊
The cost of washing a brick house is rarely fixed. Several variables play a role, and each can shift the final price significantly.
1. Size of the property
Larger homes have more brickwork, which means:
- More labour time
- More water usage
- Longer setup and pack-down
This is one of the most direct cost drivers.
2. Height and access requirements
Height affects pricing because of access needs. A single-storey property is cheaper to clean than a three-storey townhouse.
| Height | Typical cost impact |
|---|---|
| Single storey | Base price |
| Two storeys | +15% to +25% |
| Three storeys | +30% to +50% |
The use of scaffolding, towers, or specialist access equipment increases costs further.
3. Level of soiling
Brickwork condition matters. Light surface dirt is quicker to remove than heavy staining.
| Condition of brickwork | Cost effect |
|---|---|
| Light dirt | Standard rate |
| Moderate algae or pollution | +10% to +20% |
| Heavy staining or moss | +25% to +40% |
Older properties in urban or coastal environments often fall into higher brackets.
4. Cleaning method used
Different methods come with different cost structures. The price reflects equipment, training, and time involved rather than effectiveness alone.
| Cleaning method | Typical cost range |
|---|---|
| Low-pressure wash | £5 – £8 per m² |
| Heated wash | £7 – £10 per m² |
| Specialist brick cleaning systems | £9 – £12 per m² |
5. Mortar condition
If mortar joints are fragile or weathered, the cleaning process must be slower and more controlled. This increases labour time and therefore cost, even though no repair work is included.
6. Surroundings and obstacles
Properties with extensions, conservatories, neighbouring buildings, or limited access routes often take longer to work around.
| Access difficulty | Price adjustment |
|---|---|
| Clear access | No change |
| Partial obstruction | +10% |
| Restricted access | +20% to +35% |
Labour and time breakdown ⏱️
The majority of the cost comes from labour rather than materials. Washing brickwork is time-intensive, especially when detail and consistency are required.
Typical time requirements
| Property size | Estimated labour time |
|---|---|
| Small house | 1 day |
| Medium house | 1–2 days |
| Large house | 2–3 days |
Labour costs are usually calculated into the total price rather than listed separately, but daily labour values often range between £200 and £350 per worker.
Regional price differences within the UK
Prices vary depending on location due to labour rates and operating costs.
| Region | Average price variation |
|---|---|
| London & South East | +15% to +30% |
| South West | +5% to +15% |
| Midlands | Average |
| North of England | −5% to −15% |
| Scotland & Wales | −5% to +10% |
These differences can significantly affect overall cost for identical properties.
Additional cost elements
Some costs are not obvious at first glance but still influence the final figure.
Water usage
While water itself is relatively inexpensive, high-volume cleaning can still add a small cost.
| Property size | Approximate water cost |
|---|---|
| Small house | £5 – £10 |
| Medium house | £10 – £15 |
| Large house | £15 – £25 |
This is normally absorbed into the total price rather than listed separately.
Waste management
Dirty runoff, debris, and organic matter must be managed responsibly. Properties with heavy biological growth may require additional cleanup time.
Weather dependency
Interrupted work due to rain or frost can increase labour hours. While this is not usually charged as a separate line item, it influences pricing buffers.
Cost comparison: brick washing vs leaving brickwork unwashed
While this text does not suggest actions, it is useful to compare costs numerically.
| Scenario | Cost over 10 years |
|---|---|
| Brick washing every 5 years | £800 – £2,400 |
| No washing (visual degradation only) | £0 |
| Later intensive cleaning | £1,200 – £2,000 |
This table illustrates how timing can affect overall expenditure without implying a preferred approach.
Periodic cost overview
Brick washing is not usually an annual expense. The frequency varies by environment and exposure.
| Interval | Typical cost per wash |
|---|---|
| Every 3 years | £600 – £1,200 |
| Every 5 years | £700 – £1,400 |
| Every 8–10 years | £900 – £1,800 |
Older vs newer properties 🏠
Age influences pricing due to brick hardness, mortar composition, and staining patterns.
| Property age | Cost tendency |
|---|---|
| Under 20 years | Lower end of range |
| 20–60 years | Average |
| 60+ years | Upper end of range |
Older brickwork often requires slower cleaning speeds, increasing labour time.
Detached, semi-detached, and terraced cost comparison
| Property type | Typical cost | Key cost driver |
|---|---|---|
| Terraced | £400 – £650 | Limited wall area |
| Semi-detached | £600 – £900 | Shared walls |
| Detached | £800 – £1,500 | Full exposure |
Detached homes usually have all elevations exposed, increasing surface area and access time.

Washing a brick house is best understood as a variable-priced service, shaped by physical and environmental factors rather than a universal fee. The wide range of prices reflects the diversity of housing styles, brick types, and site conditions found across the UK. 🧱✨
Impact of extensions and add-on structures 🧱➕
Extensions, bay windows, porches, and garages increase the complexity of washing brickwork. These features create additional corners, edges, and shadowed areas where dirt tends to build up. While they may not dramatically increase total wall area, they often slow down the cleaning process.
| Feature type | Typical cost increase |
|---|---|
| Single-storey extension | +£50 – £120 |
| Garage (attached) | +£70 – £150 |
| Bay windows | +£40 – £100 |
| Multiple add-ons | +£150 – £300 |
The increase reflects labour time rather than materials.
Cost differences between front, rear, and side elevations 🏠↔️
Not all sides of a property cost the same to wash. Rear and side elevations often have heavier organic growth due to shade and limited airflow.
| Elevation | Cost tendency |
|---|---|
| Front | Lower |
| Side | Average |
| Rear | Higher |
In pricing terms, rear elevations can add 10%–20% more time compared to the front due to algae and moss buildup.
Seasonal pricing variations 📅
The time of year can influence brick washing costs. Warmer, drier months allow for faster working conditions, while colder seasons slow down the process.
| Season | Typical cost effect |
|---|---|
| Spring | Average |
| Summer | Slightly lower |
| Autumn | Average |
| Winter | +10% to +20% |
This adjustment reflects reduced daylight hours and weather-related delays.
Cost impact of decorative brickwork and detailing 🧩
Decorative brick features such as arches, soldier courses, or patterned brickwork require more detailed cleaning. These areas are slower to clean evenly and carefully.
| Decorative element | Cost impact |
|---|---|
| Simple detailing | +£40 – £80 |
| Multiple features | +£100 – £200 |
| Extensive ornamental brickwork | +£200+ |
The additional cost accounts for precision rather than surface size.
Short-term vs long-term cost expectations ⏳
Brick washing costs can look different depending on the timeframe considered. A one-off clean may sit at the higher end of pricing, while periodic maintenance tends to stabilise costs.
| Time approach | Typical cost range |
|---|---|
| One-off intensive wash | £900 – £1,800 |
| Periodic washing | £600 – £1,200 |
| Long-gap cleaning | £1,200 – £2,000 |
This comparison highlights how accumulated dirt influences labour intensity and overall pricing.
