Common questions in Little Woodcote
Could a tired shower seal in my Little Woodcote flat affect the neighbours below?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
I let a flat near Woodmansterne station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Does remedial work come with a guarantee?
Yes, with our 12-month guarantee. If we have pointed out another problem, getting it fixed helps the new joint last.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you cover Little Woodcote?
Yes, we do. Our applicators work in Little Woodcote.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
How we handle remedial sealant in Little Woodcote
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. We work on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints, and common reasons people get in touch are black mould underneath the bead and gaps opening along the back of the worktop.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Little Woodcote are no different.
There’s a 12-month guarantee on every job, large or small.

Do you need remedial sealant in Little Woodcote?
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.
If you can see any of these, it’s time to have the joints looked at:
- Beads that never stuck properly
- Mould trapped under a layer of silicone
- A second bead peeling off the first
- Gaps opening along the back of the worktop
Schools such as Woodmansterne Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What your quote should include
- How much experience the applicator has

- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.

Advice
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What remedial sealant looks like in Little Woodcote
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
In the older streets around St. Patrick's Church, walls and floors in older homes can move, and sealant and grout show it first. Little Woodcote is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What affects the cost of remedial sealant
We do not publish a price list, because no two jobs are the same. What we look at:
- The product the joint needs
- How many areas need sealing
- Mould in or behind the old joints
- The size of the job
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
We quote each job on its own, so start by telling us what you need. Simply ring 0345 464 0079 or email us and describe the job.
Leave it or put it right?
Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear price for the lot.

Surface by surface
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. Both are checked before we reseal.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned before backing and resealing.
