FAQs
1 / What is DOFF steam cleaning and when is it used?
DOFF cleaning uses high-temperature, low-pressure steam to gently remove dirt, algae, paint, and biological growth from stone surfaces. It’s ideal for delicate stone, listed buildings, and heritage properties, as it cleans effectively without causing damage or saturation.
2 / What is the TORC system and when is it used?
The TORC system is a gentle abrasive cleaning method that uses a mixture of air, water, and fine inert media. It’s typically used for removing heavier soiling, paint, carbon staining, or coatings where steam cleaning alone may not be enough.
3 / When should DOFF be used vs TORC?
DOFF is best for general cleaning, algae, and sensitive surfaces, especially on listed or historic buildings where preservation is critical.
TORC is used for more stubborn issues, such as paint removal or heavy staining, where a slightly more mechanical approach is needed.
4 / Will stone cleaning damage my property?
No, when carried out correctly. At KP Stone Care, we use low-pressure, specialist systems like DOFF and TORC, carefully selected for each surface. This ensures effective cleaning without damaging the stone or mortar.
5/ Can you work on listed buildings?
Yes, we regularly work on listed and heritage buildings across Oxfordshire and the Cotswolds. Our methods are conservation-led, ensuring the stone is cleaned and preserved in line with best practices.
6/ What types of stone can you clean?
We work with a wide range of materials, including limestone, sandstone, Cotswold stone, and other natural stone surfaces. Each project is assessed individually to ensure the correct cleaning method is used.
7/ Do you offer lime mortar repointing?
Yes, we specialise in traditional lime mortar repointing, which is essential for older and listed buildings. This helps maintain the structure, breathability, and long-term condition of the stonework.
8/ How long does stone cleaning take?
This depends on the size of the property and the level of cleaning required. Smaller jobs may take a day, while larger or more complex projects can take several days. We provide a clear timeframe after assessing the site.
9/ Do you provide free quotes?
Yes, we offer free, no-obligation site assessments across Oxfordshire and the surrounding areas. We’ll inspect the stonework and recommend the most suitable approach.
