Check tile material, grout condition and damp before choosing a cleaning method. Questions to ask about tiled floors and bathrooms in London.

Why grout can look dirty when tiles look clean

Grout lines and textured tile surfaces can retain residue that a quick wipe leaves behind. The cause matters: surface dirt, limescale, damaged grout and an ongoing leak need different responses. A cleaning appointment should start with identifying the material and what is causing the discolouration.

Identify the tile before choosing a product

Ceramic, porcelain and natural stone should not be treated as interchangeable. Keep any installation or care information and send a close-up photo of the tile and grout. Ask the provider to confirm product compatibility and carry out any appropriate test. Do not assume a steam machine or acidic descaler is suitable simply because the surface is hard.

Cleaning is different from repairing grout

Cracked joints, missing grout, loose tiles and failed seals may need repair. If a mark returns because moisture keeps entering the area, cleaning alone will not resolve the source. Point out leaks, persistent damp and recent repairs before arranging a visit. Ask whether the proposed work covers cleaning only, or whether any separate repair specialist is needed.

What a useful quotation should include

Give the approximate floor or wall area, tile material if known, photographs, access details and whether the room can be left unused afterwards. Ask what is included, whether sealing is proposed, and when the surface can be used again. Sealing should be discussed as a separate material-specific decision, not an automatic extra.

Booking alongside carpet or upholstery cleaning

OneGo Cleaning Masters provides carpet and soft-furnishing cleaning. If you also need tiled surfaces assessed, describe the work before booking so availability and scope can be confirmed. Do not assume specialist stone restoration, regrouting or damp repairs are included in a carpet cleaning quote.

Questions before booking

Can every dark grout line be cleaned back to its original colour?

No. Permanent staining, wear, repairs and moisture damage can affect the result. Ask what improvement is realistic after inspection.

Should I book cleaning if the grout is cracked?

Send photos first. The provider can clarify whether cleaning is appropriate or repair needs to come first.
