How we handle regrouting in Park Royal
Across Park Royal, we regrout tiled showers, bathrooms and kitchens. Out comes the old grout, the joints are cleaned and new grout goes in, finished with new silicone at the edges. We work on bathroom wall tiles, kitchen splashbacks and bathroom floors, and common reasons people get in touch are grout in a colour the owner wants to change and grout that stays dark however much it’s cleaned.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. In Park Royal, that’s a good reason to put tired sealant and grout right early.
Each job carries a 12-month guarantee, whatever its size.

Questions from Park Royal
Could a tired shower seal in my Park Royal flat affect the neighbours below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Do you work in hotels near Park Royal?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you grout the corners?
We use silicone in corners and along edges. Grout in a moving joint soon cracks.
When can I use the shower again?
The wait depends on the materials and how warm the room is. We will give you a time to follow when the job is done.
Can you change the grout colour?
Yes, regrouting is the time to do it. Tell us the colour you’d like when you ask for a quote.
Are you fully insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
What sealant work cannot fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- Tiles that are chipped or split
- Failed tanking or waterproofing under the tiles
- Loose tiles, which need refixing first
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

What else we do in Park Royal
What we’re called out for in Park Royal
Most grout is porous, so it soaks up water, soap and dirt. Given time, it discolours and begins to break down, especially in a shower that’s used every day.
If you can see any of these, it’s time to have the joints looked at:
- Corners filled with grout instead of silicone
- Grout washed out of a shower
- Dirty, worn grout on a tiled floor
- Greasy, stained grout behind the hob
As a London address, Park Royal can be tricky for parking: let us know about parking bays, permits or a driveway.
What your quote should include
- Which sealant they’ll use, and why
- Whether VAT is included
- What happens if they find a problem under the old sealant
- How much experience the applicator has
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep harsh bleach and acid cleaners off the grout
- Stick to mild products for cleaning grout
- Look at the sealant in the corners now and then
- Do not ignore a tile that feels loose
We will tell you when the area can be used again. Please follow it, and avoid scrubbing the new grout hard for the first few days.
Stains that won’t clean are a sign the grout is breaking down. At this point it’s a simple regrout, before the joints open up.
Leave it or put it right?
New grout smeared over the old doesn’t bond well. It sits thinly on top and soon flakes away, taking any repair with it. Raking out to a consistent depth gives the new grout something to hold. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Park Royal, the repair is bigger than a sealant job.
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. You’ll know the price before we begin.

How we quote for regrouting
The price is agreed before any work begins. It’s based on:
- The product the joint needs
- Access and height
- How much there is to do
- The old material and how stubborn it is
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Where the property is
- If someone has resealed it before
- The rough size of the job
- Whether it’s a home or a business
Need a quote? Please ring 0345 464 0079 or drop us an email with a few details. You’ll know what we plan to do, and what it will cost, before any work begins.
The process
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a shower enclosure, longer for a whole room. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- First we agree what’s being done and flag any loose tiles.
- We remove the old grout carefully.
- 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.
Preparing for the visit
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
Getting a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, phone 0345 464 0079 or email us.

Park Royal homes and their sealant
Park Royal has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
For site and facilities teams at buildings such as West Twyford Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. For an older house near a landmark such as St Gabriel's Church, walls and floors in older homes can move, and sealant and grout show it first.
