About our bathroom resealing in Old Chiswick
Kitchens need the same care as bathrooms. The joint between worktop and wall, the edge of the sink and the bottom of the splashback get wet every single day, and water behind a laminate worktop can make it swell. Kitchen joints get a sealant suited to kitchens, colour-matched where it shows. We work on sinks & splashbacks, kitchen worktops & upstands and shower trays & enclosures, and common reasons people get in touch are a messy, uneven bead from a previous reseal and cracked, shrunken or lifting silicone.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Old Chiswick, getting the joints right keeps water where it belongs and the room looking clean.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

What happens if it’s left?
Dealing with sealant early is a short job: it takes half a day or less for one room, longer when the kitchen is included. Wait for a leak and you may be looking at panels off, drying out and redecorating too. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.

When to call us in Old Chiswick
Mould is the reason many people want their sealant replaced. Steamy rooms that don’t dry out give mould all the damp it needs, and once it has grown into the bead, cleaning rarely gets it out.
If you can see any of these, it’s time to have the joints looked at:
- Leaks into the floor or ceiling below
- A messy, uneven bead from a previous reseal
- Black mould in the silicone that will not clean off
- A reseal done over the top of the old bead
For landlords with property near Chiswick station, fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
What your quote should include
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant
- What guarantee comes with the work
- Whether they seal over old material or remove it
How to look after the new joints
To keep the joints looking good and working properly:
- Use gentle cleaners on the silicone
- Do not leave water standing on kitchen joints
- Let new sealant cure fully before it gets wet
- Squeegee the walls and tray after use
Mould needs damp, so keep the room aired. Run the extractor fan during and after a shower, so the silicone gets a chance to dry.
Each shower pushes a little more water through a failed joint. Over time that water reaches floors, walls and ceilings. Early resealing closes the gap before damage is done.
Old Chiswick: your questions answered
Do you work in hotels near Old Chiswick?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Could a tired shower seal in my Old Chiswick flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. A proper reseal before the leak starts is the easy fix.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you have insurance?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Is white the only colour available?
Most people choose white or clear, and other colours are available to suit tiles, trays and worktops. Let us know your preference when you ask for a quote.
Do you guarantee your resealing?
Yes, a one-year guarantee. Looking after the joint as we suggest helps it last.
Do you work in Old Chiswick?
Yes. We’re based in Crawley and work across South East England, London and Scotland, Old Chiswick included.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Bathroom resealing in Old Chiswick: local notes
There are hotels and other places to stay in and around Old Chiswick. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as The William Hogarth Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For an older house near a landmark such as St. Nicholas Church, walls and floors in older homes can move, and sealant and grout show it first.
Old Chiswick is about 2 miles south of Acton, in Greater London. Whether you are in the middle of Old Chiswick or further out, bathroom resealing is available for homes and businesses alike.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
