Black Spot Removal in Portsmouth , Portsmouth

Many homeowners in Portsmouth attempt to blast away black spots using high-pressure water, only to find the marks remain once the stone dries. This is because the lichen grows beneath the surface, feeding on the minerals within the stone. Our expert approach involves a combination of targeted chemical treatments that break down the root structure of the lichen, followed by precise hot water pressure washing. This dual-action process safely lifts the unsightly spores without causing the surface pitting or etching often associated with aggressive, unskilled jet washing.

Whether you have a high-end Indian sandstone patio or a traditional block-paved driveway, our team understands the unique requirements of different materials. We carefully manage our water pressure and chemical application to protect the mortar joints and the stone finish.
