5-Star Rated Exterior Cleaning
Restore the natural beauty, vibrancy, and structural integrity of your exterior stone surfaces. At Nutech Cleaning, we specialize in expert soft washing and steam cleaning techniques tailored for natural stone buildings, sandstone, limestone, granite, and Indian stone patios—servicing residential clients across Scotland and commercial stone cleaning projects nationwide throughout the UK. Protect your investment from organic growth, weathering, and pollution with our safe, long-lasting cleaning solutions.
Our professional stone cleaning service is designed to safely remove decades of built-up grime, algae, moss, lichen, and atmospheric pollutants without compromising the delicate surface of your stonework. Over time, external elements not only obscure the original colors and textures of stone, but embedded contaminants can also trap moisture, contributing to erosion, frost damage, and long-term surface decay. By employing specialized, non-abrasive techniques, we reverse this deterioration and restore the authentic architectural character of your property.
Every project begins with a comprehensive assessment of the stone’s specific type, age, and physical condition. Rather than using harsh, high-pressure jet washing that can pit or etch vulnerable masonry, we combine gentle soft washing solutions with targeted high-temperature steam cleaning. This dual-action approach lifts deep-seated soot, dirt, and bio-growth while preserving mortar lines and delicate stone faces. Complete with preventative biocide treatments to impede future organic regrowth, our process delivers a strikingly brighter appearance and lasting preservation for your outdoor surfaces.

We clean a wide range of natural and hard landscaping stones, including sandstone, limestone, granite, slate, marble, Yorkstone, and Indian stone patios, as well as exterior stone cladding and architectural masonry.
Standard high-pressure jet washing can easily etch porous stone, erode mortar joints, and cause irreversible surface damage. That is why we utilize low-pressure soft washing and controlled steam cleaning, which safely remove dirt and organic growth without compromising the material.
Soft washing uses eco-friendly chemical solutions applied at low pressure to kill and neutralize organic organisms like moss, algae, and lichen at the root. Steam cleaning uses low-pressure, high-temperature water vapor to melt away grease, carbon soot, and heavy grime gently without abrasive force.
Following the initial deep clean, we apply a specialist biocide treatment. This invisible protective solution penetrates deep into the pores of the stone to eliminate microscopic spores and significantly delay future biological regrowth.
Yes. Black lichen spots root deep into the pores of Indian stone and cannot be removed by water pressure alone. Our soft wash treatments chemicalize and break down the lichen structure, completely lifting these stubborn spots.
Yes. When properly applied and rinsed, our cleaning solutions are safe. We take precautions to protect adjacent foliage during treatment, and once surfaces are completely dry, cleaned areas are entirely safe for children and pets.
Nutech Cleaning provides expert stone cleaning services throughout Scotland, catering to residential, commercial, and heritage properties across cities, towns, and rural regions.
The duration depends on the size of the area, the type of stone, and the severity of staining or organic growth. Most residential patios, walls, or entrance steps can be completed within a single day.
Because atmospheric pollution and Scottish weather encourage organic growth, we recommend a professional wash and biocide treatment every 2 to 4 years to maintain optimal appearance and structural protection.
