Cleaning to the Highest Standards


Take cleaning and protecting your property to the highest standards with Keystone Preservation. We pride ourselves on providing unique cleaning solutions to every building we visit, using only the best products to create quality results. So what is the key to our success? What makes us different and what does this mean for our customers?


We pride ourselves on our accreditations, ensuring we are the most qualified and use the highest spec equipment in order to provide our clients with the best service. At present, these include DOFF, IPAF, SPAB and Stonehealth.



DOFF is our primary cleaning equipment. The ultra-high temperature system kills off the bacteria, which means regrowth is prohibited and so is the cost of further treatment. In comparison to traditional pressure washers, steam cleaning can offer that deeper clean and stain removal without containing any cleaning agents. No chemicals, no damage, no problem.



Stonehealth is a UK based company trading the most reliable and ethical products, including the revolutionary DOFF system. Not only do Stonehealth supply such products, but they also provide in-depth training as to how to use their specialist systems. Keystone Preservation proudly hold their position on Stonehealth’s approved list of companies, as a result of operating equipment safely and responsibly.



The Internal Powered Access Federation (IPAF) promotes safe and effective use of powered access equipment worldwide. IPAF provide technical advice and information through legal infrastructure, training programmes and safety initiatives. As a registered member of IPAF, Keystone Preservation has and will continue to undertake globally recognised training in order to promote safe practice during preservation. With this, we can ensure that maximum results are achieved with no damage to your building or the surrounding environment.



The Society for Protection of Ancient Buildings (SPAB) is an initiative that we take great pride in collaborating with. SPAB aims to counteract the damaging effects of restoration and is the largest pressure group fighting to save prehistoric buildings from damage and decay. Thanks to SPAB, we have a comprehensive understanding and practical knowledge about how historic buildings should be maintained and we have the confidence to implement the most effective cleaning solutions for every unique case.


The key to our success is four-fold. Thanks to DOFF, Stonehealth, IPAF and SPAB we can provide specialised, safe, eco-friendly and cost effective cleaning solutions for each individual customer.


We are also consistently looking for ways to improve and provide the best quality and safest service. With this in mind, we look forward to maintaining and adding to our accreditations in 2017.
