Additional costs to consider include:
- Scaffolding: If your Bath stonework is on a high or difficult-to-reach location, you may need scaffolding. Scaffolding hire can range from £400 to £1,200 depending on the height and duration of the project.
- Permit Fees: If you're cleaning stonework on a listed building or in a conservation area, you may need a permit. Permit costs can vary, so it’s best to check with your local council.
Types of Bath Stone Cleaning Methods
There are several methods used to clean Bath stone, each with its own advantages and drawbacks:
Pressure Washing
Pressure washing is the most common and cost-effective method. It uses high-pressure water to remove dirt and grime from the surface. However, it can be harsh on the stone, especially if done improperly, leading to erosion or damage. Therefore, it’s critical to hire professionals experienced with Bath stone to avoid any harm.
Chemical Cleaning
Chemical cleaning involves the use of specific cleaning agents to break down stains, algae, and moss that are deeply embedded in the stone. This method is especially effective for older, more weathered stone but can alter the stone’s original colour and texture. It’s often recommended to test a small area before applying chemicals to the entire surface.
Gentle Brushing and Water
This method uses soft brushes and water to gently scrub away dirt and grime. It’s ideal for delicate Bath stone and can preserve its natural texture. However, it’s a slow process and may not be suitable for heavily stained or large areas.
Steam Cleaning
Steam cleaning uses heat and steam to lift dirt from the stone without chemicals. This method is gentle on the stone and environmentally friendly, but it’s more time-consuming and costly compared to other methods.
FAQ's
1. How often should I clean my Bath stonework?
Cleaning frequency depends on the location of the stone and exposure to pollution or weathering. For most buildings, cleaning every 2 to 3 years should be sufficient.
2. Can I clean Bath stone myself?
While it’s possible to clean Bath stone yourself, it’s usually better to hire a professional, especially for large or delicate stone areas. DIY cleaning could lead to damage if the wrong technique or pressure is used.
3. Will cleaning affect the appearance of my Bath stone?
Depending on the method used, cleaning may alter the appearance of the stone. Pressure washing may remove some of the patina, while chemical cleaning can affect its colour. It’s essential to choose the right method based on the stone’s condition.
4. Can I use a chemical cleaner on all Bath stone?
Not all Bath stone is suitable for chemical cleaning. It’s essential to test a small area first to ensure the stone reacts well to the chemicals. For historic or highly sensitive stone, steam cleaning or gentle brushing may be a safer option.
Conclusion
Cleaning Bath stone is a worthwhile investment to preserve the aesthetic and structural integrity of your property. The costs can vary, but on average, you can expect to pay between £10 to £40 per m² depending on the cleaning method and location. If you have extensive stonework or require scaffolding, your costs may increase. Always consider the pros and cons of each cleaning method and consult a professional to ensure the best care for your Bath stone.
