Remedial sealant for Harbourland and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- Sealant that came away because the surface wasn’t prepared
- Products that weren’t meant for the joint
- Over-sealed joints coming away
How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours, depending on how many layers have to come out. In a small place like Harbourland, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- 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.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts

Remedial sealant in Harbourland
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We are fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. We work on expansion joints, failed movement joints and botched or over-sealed joints, and common reasons people get in touch are smears and lumps from a botched reseal and mould trapped under a layer of silicone.
In a village or hamlet like Harbourland, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
There’s a 12-month guarantee on every job.

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
What the job involves on each surface
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.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed.
Aftercare tips
A little care helps the new joints last. We recommend:
- Find out why the sealant failed first
- Keep bleach and abrasives off the bead
- Do not add new sealant on top of old
- Have loose fittings fixed before resealing
Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
Why deal with it now?
Ripping out a bathroom isn’t usually needed. If the bath, tray and tiles are sound, remedial resealing usually puts it right. Where something else has failed, you will hear it from us. Around Harbourland, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

When to call us in Harbourland
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, cannot stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
The problems people normally mention when they call include:
- A shower that leaks however often it’s resealed
- Products that weren’t meant for the joint
- Gaps opening along the back of the worktop
- Movement joints that have split or pulled away
For an older house near a landmark such as St Paul's Church, walls and floors in older homes can move, and sealant and grout show it first.
