Remedial sealant in Coombe
A joint that keeps failing generally has a reason. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will beat any new bead. We look for the cause before we reseal. We are often asked to deal with smears and lumps from a botched reseal and kitchen joints letting water behind the worktop, across leaking tray & enclosure joints, failed movement joints and mouldy bath & shower sealant.
For a small place like Coombe, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. In the bathroom or kitchen, the work is the same as in any town.
There’s a 12-month guarantee on every job.

Why deal with it now?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a small place like Coombe, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What remedial sealant looks like in Coombe
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you live in an older home near Church of St Nicholas, walls and floors in older homes can move, and sealant and grout show it first. Letting a property close to Sandwich station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

- Movement from fittings that are not supported

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on how many layers have to come out and we leave things clean and tidy. Somewhere as small as Coombe, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints

Advice
Common problems we fix in Coombe
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould. At that point it has to come out.
It’s worth asking for a quote if you see:
- Floor or wall movement joints that have failed
- Gaps opening along the back of the worktop
- Smears and lumps from a botched reseal
- Sealant peeling off a dusty or damp surface
Managing a site like Ash Cartwright and Kelsey Church of England Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Common questions in Coombe
Can you help a landlord with a rental near Sandwich station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Is Coombe within the area you cover?
Yes. Coombe is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us.

How the job changes by surface
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Movement & expansion joints
A movement joint must be able to stretch. We remove the failed sealant, fit backing and reseal.
