The refined hamlet of Cowley, situated at the confluence of the River Exe and the River Creedy just north of Exeter, presents a unique and demanding environment for professional exterior cleaning services. At Extreme Property Solutions, our exterior cleaning service is bespoke-engineered to address the intense organic colonisation and atmospheric pressures unique to this low-lying, riverine location. Cowley’s geography, defined by its position on the rich alluvial floodplains and its proximity to the bustling transport corridors of the A377 and the railway, creates a microclimate characterised by extremely high humidity, frequent mists, and a significant deposition of urban and traffic-related pollutants. This environment acts as a massive incubator for complex organic biofilms. Properties in Cowley, ranging from the historic Grade II listed Cowley Bridge and the substantial manor houses to modern riverside apartments and traditional stone cottages, frequently exhibit advanced infestations of green algae, black fungal mould, and the resilient red algae (Trentepohlia). This red algae is particularly prominent here, often manifesting as deep orange streaks that can permanently stain modern monocouche renders and the light-coloured stone finishes characteristic of the area’s prestigious properties if not treated with professional biocides. Furthermore, the area’s proximity to major roads leads to a high concentration of carbon soot and traffic-related grime. These contaminants combine with the damp river air to form a stubborn, acidic film on building envelopes, which can cause deep staining on roof tiles and masonry. These pollutants do more than cause unsightly staining; they root into the microscopic pores of renders and stone, where organic acids and carbon deposits can chemically degrade the substrate. Our professional exterior cleaning approach for Cowley is designed to be both restorative and protective. We strictly avoid high-pressure jet washing, which is catastrophic for the hamlet’s heritage masonry and delicate renders. Instead, we utilise advanced soft-washing technology. This involves the application of HSE-approved, pH-neutral biocides at very low pressure. These specialised solutions penetrate deep into the substrate to kill the organic growth at its root, providing a sanitised clean that lasts significantly longer than traditional methods. For roof cleaning, we employ a non-aggressive manual scrape followed by a biocidal treatment to ensure the structural integrity of the tiles or slate is maintained while removing heavy moss loads that thrive in the damp river air. We also provide intensive gutter clearance and professional driveway restoration, ensuring that every element of the property’s exterior is returned to a pristine condition. By removing the ‘biological load’ and acidic pollutants, we prevent the chemical degradation that leads to water ingress. Our team conducts a detailed site survey for every Cowley project, identifying material sensitivities to ensure the most appropriate cleaning agents are used. The result is a total restoration of the property’s aesthetic, ensuring it remains a source of pride within this historic and elegant gateway to Exeter. We pride ourselves on delivering a finish that is not only visually transformative but also functionally protective, stopping the cycle of decay caused by the persistent river dampness and urban pollutants. Our mission is to preserve the architectural heritage of Cowley while providing modern, scientifically-backed cleaning solutions that offer the highest level of protection against the elements.

100% Customer Satisifaction
Choosing Extreme Property Solutions for your exterior cleaning in the historic hamlet of Cowley means partnering with a team that truly understands the complexities of Exeter’s peri-urban and riverine architecture. We are the premier choice in the Exeter and Upton Pyne area because we prioritise the safety and longevity of your building’s exterior through the science of soft-washing. In a high-humidity, riverine setting like Cowley, using high pressure on building surfaces is a major risk, often leading to permanent scarring and faster organic return due to the increased surface area created by pressure-induced pitting. Our low-pressure systems safely sanitise your property’s exterior, preserving the texture and colour of K-Rend, traditional stone, and delicate lime finishes. We are surface restoration experts who understand the specific biological and chemical loads of the Exe and Creedy valleys. Our commitment to the community is absolute; we are fully insured and our technicians hold IPAF and PASMA certifications for safe work at height, ensuring we can treat even the most substantial three-storey riverside homes and gable ends safely. Being in an ecologically sensitive area near the confluence of two major rivers, we take our environmental responsibilities very seriously. We use only eco-friendly, biodegradable biocides that are safe for your gardens, pets, and the local ecosystem once dry, ensuring that our run-off never impacts the local river environment or wildlife. We provide transparent, fixed-price quotes and a thorough site tidy-up, ensuring a professional experience from start to finish. Our treatments offer a residual protection that keeps surfaces clean for up to three years, providing a much higher return on investment than standard pressure washing. We have a solid reputation for reliability and quality across the Exeter area. We treat every Cowley property—from the historic manor houses to the modern riverside developments—with the same meticulous attention to detail.
