At JCM, we believe that maintaining your property’s exterior shouldn't be a gamble.
Living along the stunning Cornish coast comes with incredible views, but it also subjects homes and commercial properties to some of the UK’s most aggressive weather. From corrosive sea salt spray and relentless rain to stubborn red algae and lichen growth, keeping a property clean here requires far more than a standard jet washer and a bucket of soapy water.
JCM was founded on our customer focused dedicated promise.
Providing a fully insured, modern, and highly professional exterior restoration service that puts property longevity, safety, and client trust above quick, cheap fixes
We are a local, family run dedicated professional team with a passion to deliver the best service to our customers.
We offer 100% Satisfaction guarantee and provide honest, realistic advice to deliver exactly what we promise.
We respect your time and your property. That means prompt communication, arriving on schedule, providing clear itemised quotes with zero hidden fees, and leaving your site spotless, bagging up and removing all cleared debris when we finish.
We take the time to visit you in person to accurately obtain the information to provide you a free quote, ensuring we're proposing exactly what you need, right the first time.
No more worrying about ladders leaning against delicate guttering or unvetted traders on your roof. JCM invests in the best, safety first technology, allowing us to clean more efficiently whilst protecting our staff and your property.
Every job we perform is backed by comprehensive Public Liability Insurance and completed by fully trained, staff.
We understand the unique environmental challenges faced by properties in Newquay, Truro, St Ives, and right across the county. We know how salt crust binds to glass, how red algae (Trentepohlia) attacks Cornish render, and how ocean winds impact rooflines. Our methods are purpose-built for the harsh Cornish climate.
Where unvetted operators blast modern renders, historic granite, and timber decking with high-pressure water—causing cracking, splintering, and blown seals—JCM tailors every job. We utilise delicate soft-wash systems, variable low-pressure surface washers, and 100% deionised pure water technology to gently restore surfaces without risking your property's integrity.
