How the job changes by surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned before backing and resealing.
Remedial sealant in Bray Wick
Movement and expansion joints fail when the sealant can’t stretch. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. If you have thick, messy sealant smeared over tiles and gaps opening along the back of the worktop, we can help, whatever the surface.
Homes around Bray Wick are mostly houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Questions from Bray Wick
Do you cover smaller places like Bray Wick?
Yes, Bray Wick is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for hotels and guest houses in Bray Wick?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How do I get a quote for remedial sealant in Bray Wick?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or email us and tell us what needs doing and where.
Does remedial work come with a guarantee?
Yes. You get our 12-month guarantee.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
How long does the work take?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours, and we confirm the time with your quote.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Remedial sealant in Bray Wick: local notes
Bray Wick has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
For site and facilities teams at buildings such as Holyport CofE Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around St Michael's Church, walls and floors in older homes can move, and sealant and grout show it first.

Do you need remedial sealant in Bray Wick?
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
People usually contact us when they notice one of these:
- Beads that never stuck properly
- Over-sealed joints coming away
- Caulk or the wrong sealant used in a wet area
- Worktop sealant that has shrunk and split
If you let a flat or house near Maidenhead station, a joint that keeps failing is best fixed properly while the property is empty.
Questions to ask before booking
- Who does the work, and how experienced they are
- How hidden problems are handled
- When the joint can take water or movement
- How the colour is chosen
What happens if it’s left?
Adding more sealant is the usual quick fix, and it rarely works. It does not grip the old layer, so the leak carries on and there’s now more to remove. Around Bray Wick, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

When it isn’t the sealant
We will not take on work that will not last, so here’s what sealant can’t put right:
- Tiles that have come away from the wall
- Cracks in the fitting rather than the joint
- A leaking trap, valve or supply pipe

How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours, depending on how many layers have to come out. Somewhere as small as Bray Wick, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
