Remedial sealant in Up Somborne: local notes
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.
Homes close to All Saints Church include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. In and around Up Somborne, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Remedial sealant in Up Somborne
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 beat any new bead. We look for the cause before we reseal. We work on botched or over-sealed joints, mouldy bath & shower sealant and leaking tray & enclosure joints, and people most often call us about dark patches showing through the sealant and over-sealed joints coming away.
Around Up Somborne, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
All our work comes with our one-year guarantee, wherever you are in Hampshire.

Up Somborne: your questions answered
Will you come out to Up Somborne?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is remedial sealant in Up Somborne guaranteed?
All our work, in Up Somborne and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you reseal a split movement joint?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, then the joint is sealed properly.
Can old silicone be taken off without scratching the tiles?
Yes. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. Any existing damage is pointed out before any work starts.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
When it is not the sealant
We’ll always be straight with you, so here’s what new sealant will not do:
- Tiles that have come away from the wall
- Plumbing leaks behind walls or under trays
- A tray or bath that’s cracked
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Failed movement joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Expansion joints
- Leaking tray & enclosure joints
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

How we quote for remedial sealant
For a quick quote, just ask. The main things that affect it are:
- How many areas need sealing
- Access and height
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- The problem you’ve noticed
- Whether it’s a home or a business
- How we’d reach the joints
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or email us.
Leave it or put it right?
Another bead over the top will not fix a failed joint. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. In a small place like Up Somborne, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

What the job involves on each surface
Mouldy bath & shower sealant
Repeat mould usually points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal colour-matched to the worktop.
Landlord and commercial work in Up Somborne
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
What we do, step by step
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for most joints, depending on how much old sealant has to come out in most cases. Somewhere as small as Up Somborne, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work
