Remedial Sealant in Colden Common
We cover Colden Common for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly.
- Floor or wall movement joints that have failed
- Kitchen joints letting water behind the worktop
- Mould trapped under a layer of silicone
Why deal with it now?
Mould under a bead cannot be reached by cleaning. The layers have to come out, so the joint can be treated and resealed. In a smaller place like Colden Common, 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.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

How we handle remedial sealant in Colden Common
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we will tell you rather than reseal something that will not fix it. We work on failed movement joints, leaking tray & enclosure joints and shrunken worktop sealant, and the jobs we see most are sealant that came away because the surface wasn’t prepared and black mould underneath the bead.
In and around Colden Common, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Colden Common questions
Can you help a landlord with a rental near Shawford station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Is Colden Common in your area for remedial sealant?
Yes, Colden Common is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
How long does the work take?
Longer than a simple reseal, because every layer has to come out. Most jobs take a few hours.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, so we find that first.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. In a smaller place like Colden Common, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
Ask for a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Advice
Do you need remedial sealant in Colden Common?
Water from somewhere else can ruin a good seal. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
If you can see any of these, it’s time to have the joints looked at:
- Repeat leaks from the same joint
- Worktop sealant that has shrunk and split
- Thick, messy sealant smeared over tiles
- Torn expansion joints
Homes close to Church of the Holy Trinity include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.
Questions to ask before booking
- Whether they’re fully insured
- When the joint can take water or movement
- How the joint is cleaned and prepared
- Whether VAT is included
Surface by surface
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
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.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
We also work for property managers and facilities teams in Colden Common and across Hampshire. Several sites can go on one quote.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Deal with small splits early
- Get the cause of a repeat leak found before resealing
- Check trays and worktops don’t move
- Keep movement joints clear of mortar and paint
Where we have pointed out another fault, have it put right, or the new joint may fail again.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.

Bathrooms and kitchens in Colden Common
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
