Remedial sealant for homes and businesses in Belhaven
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. We work on shrunken worktop sealant, mouldy bath & shower sealant and failed movement joints, and common reasons people get in touch are kitchen joints letting water behind the worktop and movement joints that have split or pulled away.
Bathrooms in smaller places like Belhaven work just as hard as those in the cities. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Belhaven homes and their sealant
Belhaven is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. There are hotels and other places to stay in and around Belhaven. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Rented homes near Dunbar station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why deal with it now?
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. In an older home around Belhaven, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.

Do you need remedial sealant in Belhaven?
Movement tears sealant that is not designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes split any bead that’s too stiff or too thin.
The most common problems we see are:
- Caulk or the wrong sealant used in a wet area
- A second bead peeling off the first
- Thick, messy sealant smeared over tiles
- Movement joints that have split or pulled away
For an older house near a landmark such as Belhaven Church, walls and floors in older homes can move, and sealant and grout show it first.
What your quote should include
- When the joint can take water or movement
- Who does the work, and how experienced they are
- How the colour is chosen
- How hidden problems are handled
Different surfaces, different methods
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Clean sealant with mild products only
- Run the fan after every shower
- Report a tray that rocks or a worktop that lifts
- Find out why the sealant failed first
Keep the room ventilated: use the extractor or open a window after showering.
Signs to act on: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied and we leave things clean and tidy. Around Belhaven, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

Advice
Your questions about remedial sealant in Belhaven
Do you cover smaller places like Belhaven?
Yes. Belhaven is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for hotels and guest houses in Belhaven?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can you take off two layers of silicone?
Yes. We remove every layer; over-sealing fails because silicone will not bond to silicone.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The product needed can limit the range.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
