Signs you need remedial sealant in Highbridge
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, and tears at the first real movement. Backing sets the depth and stops that.
Look out for these signs:
- Black mould underneath the bead
- A shower that leaks however often it’s resealed
- Gaps opening along the back of the worktop
- Caulk or the wrong sealant used in a wet area
For an older house near a landmark such as St Mary's Church, older homes can move a little, which is hard on rigid grout and tired sealant.

About our remedial sealant in Highbridge
If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have photos when you phone 0345 464 0079 or email us. We work on shrunken worktop sealant, mouldy bath & shower sealant and failed movement joints, and people most often call us about sealant that came away because the surface wasn’t prepared and wide, uneven beads that look worse than the old ones.
Somewhere as small as Highbridge, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
A one-year guarantee comes as standard.

Do you cover smaller places like Highbridge?

What does remedial sealant cost?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email with a short description of the job.
Do you offer different sealant colours?
In most cases you can choose. We will tell you which colours the right product comes in and agree one before work begins.
How long before the joint can be used?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you remove sealant that’s been put over old sealant?
Yes. Each layer is cut out and the residue cleaned off, then the joint is resealed once.
What the job involves on each surface
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning.
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. Where it can be raked out, we replace it with flexible sealant.
What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before we start. Most jobs take a few hours, depending on how many layers have to come out. Somewhere like Highbridge needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints

Advice
What affects the cost of remedial sealant
We do not publish a price list, because jobs vary so much. The quote depends on:
- Any mould that needs treating
- How easy the joints are to reach
- The type of sealant required
- How much old sealant there is and how hard it is to remove
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.
What we need to know
To make quoting easier, let us know:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- The address or postcode of the job
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.

Leave it or put it right?
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Older cottages and farmhouses around Highbridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
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.
