Slate and sandstone are both durable, natural stones that add warmth and character to any space. However, due to their porous nature, sensitivity to staining, and wear over time, they require specialist care to maintain their original beauty. Our advanced restoration techniques, including deep cleaning, surface refinishing, sealing, and stain removal, restore the natural richness and colour of your slate and sandstone floors. Get in touch for details.
OUR EXPERT SLATE & SANDSTONE RESTORATION SERVICES
DEEP CLEANING & STAIN REMOVAL – RESTORE THE NATURAL BEAUTY
Slate and sandstone are prone to dirt buildup, discoloration, and stains, especially in grout lines and textured surfaces. Our deep cleaning process removes ingrained dirt and surface contaminants without damaging the stone. We use professional-grade alkaline cleaners and diamond abrasives to safely clean and rejuvenate your floors, bringing out their natural colours.
SEALING & PROTECTION – LONG-TERM DURABILITY
Due to their porous nature, slate and sandstone require sealing to protect against moisture, spills, and staining. After deep cleaning, we apply a high-performance impregnating stone sealer to enhance colour, longevity, and stain resistance, keeping your floors looking pristine for longer.
SLATE & SANDSTONE SURFACE REFINISHING – ENHANCE & RESTORE
Our surface refinishing techniques help remove scratches, restore colour, and improve stain resistance. Whether you prefer a natural matte finish or a colour-enhanced wet-look effect, we tailor the restoration process to achieve your desired finish.
SLATE FLOOR CLEANING & RESTORATION
Slate is a metamorphic rock, formed by intense heat and pressure over time. It is known for its natural layers, rich textures, and deep colours, which can range from black, dark green, and grey to reds, purples, and tans depending on its mineral composition. Although less porous than other natural stones, slate still requires regular maintenance and professional restoration to prevent dirt buildup and surface wear.
OUR SLATE CLEANING & RESTORATION PROCESS
✔ Deep Cleaning – Using alkaline cleaners and diamond abrasives, we remove dirt, stains, and discoloration.
✔ Grout Line & Edge Cleaning – Hand-cleaning grout and edges to remove dirt trapped in crevices.
✔ Surface Refinishing & Colour Enhancement – Applying impregnating sealers or colour enhancers for a rich, vibrant finish.
SANDSTONE FLOOR CLEANING & RESTORATION
Sandstone is a sedimentary stone, composed of compacted sand, minerals, and organic materials, giving it a unique textured appearance and warm, earthy tones. However, sandstone is highly porous, making it prone to staining and requiring specialist care to maintain its natural beauty.
OUR SANDSTONE CLEANING & RESTORATION PROCESS
✔ Deep Cleaning – Using heavy-duty rotary machines, alkaline cleaners, and diamond abrasives to remove embedded dirt
✔ Hand-Cleaning Grout & Edges – Ensuring thorough cleaning in hard-to-reach areas
✔ Sealing & Protection – Applying a colour-enhancing impregnating sealer to protect the stone while preserving its natural look
BEFORE & AFTER: THE DIFFERENCE WE MAKE
Over time, slate and sandstone floors can become dull, stained, and worn due to daily wear and environmental factors. Using expert cleaning, refinishing, and sealing techniques, we restore and enhance their natural character, ensuring they remain a beautiful feature in your home or business.
