About our remedial sealant in Sompting
Two decades of sealant work means we recognise most failures quickly. We’re ARBOMaster approved and fully insured, and remedial work carries our one-year guarantee. We work on failed movement joints, expansion joints and botched or over-sealed joints, and common reasons people get in touch are caulk or the wrong sealant used in a wet area and mould trapped under a layer of silicone.
Homes around Sompting 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.
You get a one-year guarantee, the same in Sompting as everywhere else we work.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
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.

Sompting homes and their sealant
Sompting is within about 2 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around St Peter the Apostle, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you look after a building such as Sompting Village Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Why deal with it now?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In a smaller place like Sompting, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email.

Common problems we fix in Sompting
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
Common reasons people contact us include:
- Wide, uneven beads that look worse than the old ones
- Floor or wall movement joints that have failed
- A shower that leaks however often it’s resealed
- Gaps opening along the back of the worktop
Letting a property close to Lancing station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

How we quote for remedial sealant
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- Access and height
- Any mould that needs treating
- The number of rooms or windows
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
What to tell us for a quote
To help us quote quickly, let us know:
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
- The rough size of the job
- Access, such as stairs, a lift or height
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Landlords, agents and businesses in Sompting
We also work for property managers and facilities teams in Sompting and across West Sussex. Several sites can be quoted together, and we are fully insured.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on how many layers have to come out. A visit to Sompting is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- For indoor joints, keep the area dry beforehand if you can

Common questions in Sompting
Will you come out to Sompting?
Yes, Sompting is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Lancing station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can failed expansion joints be resealed?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Someone sealed over the old bead. Can you fix it?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
