- Black mould underneath the bead
- Sealant peeling off a dusty or damp surface
- Leaks that keep coming back after resealing
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Act on a lifting corner straight away
- Keep the room well ventilated
- Don’t point over movement joints
- Report a tray that rocks or a worktop that lifts
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
Warning signs: 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.
Remedial sealant in Sundridge, done properly
Water on the floor doesn’t always mean failed silicone. 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. Common call-outs are for wide, uneven beads that look worse than the old ones and worktop sealant that has shrunk and split, on botched or over-sealed joints, expansion joints and failed movement joints.
Somewhere as small as Sundridge, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.

Surface by 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.
Leaking trays & enclosures
Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, tray edges and screen profiles included.
Common questions in Sundridge
Do you work for landlords with property near Dunton Green station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Sundridge?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is remedial work guaranteed?
Yes, with our 12-month guarantee. If we have pointed out another problem, getting it fixed helps the new joint last.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
What if the leak is not the sealant?
In that case, we tell you what we’ve found. A plumber or fitter may be needed before any new sealant goes on.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
What affects the quote in Sundridge
We do not publish a price list. What we look at:
- Mould in or behind the old joints
- Which sealant suits the joint
- Working hours on commercial sites
- How many rooms, windows or areas are involved
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
What to tell us for a quote
You don’t need to know the technical terms. Just tell us:
- Whether it’s a home or a business
- The rough size of the job
- Where the property is
- If someone has resealed it before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
What happens if it’s left?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Older cottages and farmhouses around Sundridge can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- ARBOMaster approved applicator
- Quality sealants from Arbo and Everbuild
- Tidy, careful work
- Sanitary silicone with an anti-fungal additive in wet areas

What remedial sealant looks like in Sundridge
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant. For site and facilities teams at buildings such as Combe Bank School, we reseal washrooms and kitchens in schools and businesses as well as homes. If you let a flat or house near Dunton Green station, a joint that keeps failing is best fixed properly while the property is empty.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
For landlords and businesses
If you manage several properties in or around Sundridge, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
