The Grout Doktor
FAQ
We use professional-grade tile and grout sealers tailored to each job. Depending on the surface and conditions, we select either water-based or solvent-based sealers — both designed to provide long-lasting protection for your tiles and grout.
Before recommending a sealer, our grout restoration specialist conducts a thorough on-site inspection to assess your specific needs. We carry a comprehensive range of premium clear tile and grout sealers, ensuring the best possible result for your home or commercial space.
The longevity of a tile and grout sealing service depends on several factors, including the type of sealer applied, the hardness and texture of the surface, the area's foot traffic, and the cleaning products used for ongoing maintenance.
For most professional clear sealers, you can expect protection to last up to 5 years — and in some cases up to 15 years. However, lifespan can be reduced by harsh weather conditions, abrasive cleaning methods, or the use of high-alkaline, acidic, or solvent-based cleaning products.
Using gentle, pH-neutral cleaners and following our aftercare advice will help maximise the life of your seal.
No — our penetrating sealers are designed to protect your tiles and grout without altering their original colour, texture, feel, or appearance. Once applied, your surfaces will look exactly the same, just with an invisible layer of long-lasting protection against stains, moisture, and dirt.
This makes our sealing service ideal for homeowners who want to preserve the natural look of their tiles while extending their lifespan.
