Remedial sealant in Shinfield, done properly

If a joint fails again and again, something is causing it. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. Finding that cause comes before any new sealant. We work on expansion joints, failed movement joints and mouldy bath & shower sealant, and people most often call us about sealant peeling off a dusty or damp surface and leaks that keep coming back after resealing.

Homes around Shinfield range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.

The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Aftercare tips

After the cure time, these simple habits help:

Deal with small splits early
Use a soft cloth, not a scourer, on silicone
Never seal over old silicone
Get the cause of a repeat leak found before resealing

Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.

Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.

What affects the quote in Shinfield

We quote each job individually. These are the things that affect it:

Any mould that needs treating
The amount of work
How easy the joints are to reach
The product the joint needs

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What we need to know

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

How we’d reach the joints
If someone has resealed it before
The address or postcode of the job
What’s wrong with the joints now

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.

DIY sealant or a professional job?

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 a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Why deal with it now?

Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, so the leak carries on and there’s now more to remove. Around Shinfield, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

What remedial sealant looks like in Shinfield

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Letting a property close to Reading Green Park station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For an older house near a landmark such as Church of St Mary the Virgin, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you look after a building such as Shinfield Infant and Nursery School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Yes, Shinfield is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Do you work for hotels and businesses?

Yes. We have worked for hotels, offices and other businesses.

Can failed expansion joints be resealed?

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

How the job changes by surface

Windows & doors

Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.

Leaking trays & enclosures

A cracked tray, failed valve or leaking waste needs a different fix. We’ll tell you what we find.

The process

On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours, depending on how many layers have to come out from start to finish. For a job in Shinfield, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

We look at how the sealant has failed and check for movement or a leak path.
We strip the joint completely, removing any layers below.
The joint is cleaned, treated for mould and left to dry.
Where the joint moves, backing and a flexible sealant suited to the movement go in.
The new joint is tooled neatly and we explain anything else we found.
