Your questions about regrouting in South Harrow
Can you help a landlord with a rental near Northolt Park station?
Yes. We work for landlords and letting agents as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
I live in a flat in South Harrow. Can a failed seal leak into the flat below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. Cutting out the old sealant and laying a new bead early stops it getting that far.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How do I get a quote for regrouting in South Harrow?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or send us an email with a short description of the job.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.
How soon can the shower be used after regrouting?
You’ll get a clear time from us before we go. The grout and sealant both need to cure before the shower is used.
Regrouting for homes and businesses in South Harrow
If you’ve been scrubbing grout that will not come clean, the stain is often in the grout itself. New grout is the fix that lasts and you can pick a different colour while you are at it. If you’re dealing with a grout colour that no longer suits the room and discoloured grout on otherwise sound tiles, we can help, on tiled floors, shower walls and wet rooms alike.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How we quote for regrouting
The price is agreed before any work begins. It’s based on:
- The size of the job
- The number of rooms or windows
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What to tell us for a quote
What to tell us when you ask for a quote:
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- How many joints, rooms or windows are involved
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or email us.
Surface by surface
Bathroom wall tiles
Splash areas around basins and baths stain first. We can regroute just those areas or the whole wall.
Wet rooms
Wet room grout and sealant need to be in good order. We renew both.
How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, or longer for a fully tiled room. For a job in South Harrow, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We agree the area to be regrouted and point out any loose tiles.
- Grout is raked out without chipping the tiles.
- The joints are cleaned out and vacuumed.
- The new grout goes in, then the tile faces are cleaned.
- We renew the silicone at the corners and edges.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints

There’s no standard price list. Instead, we give you a clear quote for your job. To arrange one, ring 0345 464 0079 or email us.
Advice
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Rinse soap off the tiles after each shower
- Have loose tiles looked at early
- Run the extractor fan during and after a shower
- Clean grout with a mild bathroom cleaner
Wipe the tiles down after a shower keeps water off the grout. Run the extractor fan or open a window so the grout dries between uses.
Once grout cracks, it tends to get worse. Water gets in behind and the tiles can start to loosen and early regrouting can avoid a much bigger job.

Why it’s worth doing now in South Harrow
Grout pens and paint-on colourants only cover the surface. They won’t fill gaps or keep water out, and stains can show through again. Raking out and regrouting replaces the grout itself. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

When to call us in South Harrow
Most grout is porous, so water, soap and grime soak into it. Over time it stains, softens and starts to crumble and showers that get daily use suffer most.
Look out for these signs:
- Cracked grout along the bath or tray
- Shower grout that has worn away
- A grout colour that no longer suits the room
- Dirty, worn grout on a tiled floor
Managing a site like The Welldon Park Academy? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
