Bathroom refresh services in London

 A tired, stained bathroom doesn't always need replacing. In many cases, a professional bathroom refresh can completely transform the appearance of your bathroom for a fraction of the cost of a full renovation. At Doctor Grout, we specialise in bathroom refresh services across London, restoring tiled bathrooms by removing mould, cleaning tiles, replacing silicone, restoring grout and applying professional acrylic grout paint to bring bathrooms back to life.

The bathroom shown above had suffered from years of neglect, heavy mould growth, soap residue, limescale and deeply stained grout. Rather than replacing the tiles, we restored every surface using specialist restoration techniques developed through years of experience working on bathrooms throughout London.

The restoration began with a detailed inspection to identify the cause of the staining and mould. We then used a carefully selected combination of acidic and high-alkaline cleaning solutions to break down stubborn limescale, body oils, soap residue and organic contamination without damaging the tiles. Every product was chosen specifically for the type of contamination present, allowing us to achieve a deep clean that ordinary household cleaners simply cannot match.

Once the chemical cleaning was complete, we mechanically cleaned the grout using a professional machine fitted with a carbide brush. This removes years of embedded dirt and prepares the grout for restoration. During the process we also extracted dirty water using a wet vacuum, ensuring contaminants were removed rather than simply spread around the bathroom.

Grout paint is one of the most effective ways to completely transform tired, stained, or uneven grout lines without the expense of re grouting or retiling. In this project, the existing grout was heavily soiled and deeply ingrained with dirt, which made the entire tiled area appear old and worn. Before any grout paint could be applied, it was essential to clean out the grout thoroughly to ensure strong bonding with the new coating.

Our team at Doctor Grout, specialists in professional grout restoration services in London, began by carrying out a deep mechanical and chemical clean of the grout lines. Using professional-grade tools and solutions, we removed layers of grime, contaminants, and surface residue. This preparation stage is crucial because grout paint will not properly adhere to dirty or sealed grout. By restoring the grout to a clean, porous state, we created the perfect surface for long-lasting adhesion.

Once fully cleaned and dried, we applied the chosen grout paint colour: Jasmine. This shade provides a warm, soft tone that instantly lifts the appearance of tiled surfaces. Unlike standard colourants, the product we use is an acrylic water-based sealer, designed not only to recolour the grout but also to protect it from future staining, moisture, and wear.

Porcelain tiles are known for their durability, sleek appearance, and low maintenance — but over time, even the toughest tiles can lose their lustre. One of the most common problems homeowners face is limescale build-up, especially in areas exposed to hard water, such as bathrooms, kitchens, and wet rooms. Limescale not only dulls the tile surface but can also lead to staining and discoloration if left untreated.

At Doctor Gout we specialize in professional porcelain tile restoration, bringing your surfaces back to life with precision cleaning techniques and long-lasting results. Recently, we completed a project involving heavily lime scaled porcelain tiles that had lost their shine due to years of mineral build-up.

To tackle the problem, we used a carefully controlled acid treatment designed to dissolve limescale without damaging the porcelain’s finish. 

Mouldy silicone replacement in Croydon. It's very easily done, leaving silicone until it's pretty far gone. By the time we got to this job the mould was everywhere, but with some acid, elbow grease and silicone replacement everything looked as good as new. 

Here we have a great example of bathroom tile, grout and silicone restoration. The client in this case had a go themselves at cleaning these tiles and grout as well as having professional cleaning companies come over to have a go, unfortunately when it gets to this stage the grout needs replacing completely and the tiles need the correct restoration processes. We first started by removing all mould and limescale to get a better look at the grout, it was then decided that the excising grout could not be restored and would need replacing, once the old grout was out when then got to digging out the old silicone and professionally cleaning the tiles. We then allowed everything to dry out, taking extra care to make sure there was no moisture where the new silicone would be going and then applied new grout. We let the new grout dry for 2 hours before applying the new silicone and as you can see the shower looked as good as new. This job is a very good example of professional tile restoration in action.

This black slate in Chelsea had seen better days, the surface was covered in a haze of limescale, mould and other bits that you don't really want there, the silicone and grout were also not in very good condition. Luckily black slate is very easily restored with the correct methods and processes. This again is a great example of professional tile and grout restoration. We started by cleaning the surface of the tiles with acid, this attacked the limescale making it easier to remove. This was followed by lots of scraping and machine work and then the neutralisation of the acid. We then took the old grout out before deep machine cleaning the tiles and extracting the slurry from the surface. The tiles were then left to dry, upon our return the grout was replaced followed by the silicone and the tiles were then sealed with a breathable oil based sealer, this not only sealed the tiles but also replaced the oil needed in the stone to give it back it's colour. Slate is one of our favourite stones to work with as no matter how bad it may look, you can always bring it back.
