Why Allerton Homeowners Choose Us
Allerton is one of Liverpool's busiest and most sought-after residential areas, and with that comes a huge variety of outdoor spaces. Under Pressure Exterior Cleaning has been Allerton's trusted patio and decking cleaning company for over a decade. We've restored more patios in Allerton than any other company and we're proud of the reputation that's built.
Allerton's mix of tree-lined streets and close-proximity housing means patio and decking surfaces receive significant algae and mould growth throughout the year. Our specialist biocide treatments are particularly effective at removing the green algae and black mould that thrive in Allerton's shaded, damp conditions — delivering brilliant results that last.
“Used Under Pressure for our patio — completely green with algae and black spot after years of neglect. They cleaned everything thoroughly, no mess and the finish is incredible. Looks like a brand new patio. Will definitely use them again.”
