How we handle remedial sealant in Northam
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. When the fault is elsewhere, we say so instead of resealing for the sake of it. We work on expansion joints, shrunken worktop sealant and botched or over-sealed joints, and people most often call us about gaps opening along the back of the worktop and decorators’ caulk around a bath or shower.
Even in a smaller place like Northam, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: all the old material out, the joint cleaned and dried, then new sealant or grout.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

What the job involves on each surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before we reseal.
Northam homes and their sealant
Northam 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, and sealant and grout that work that hard wear out sooner. 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.
If you let a flat or house near Bitterne station, a joint that keeps failing is best fixed properly while the property is empty. In the older streets around Church of St Augustine, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Northam is about 1 mile south-east of Southampton, in Southampton. From the centre of Northam to the outskirts, we cover remedial sealant for every kind of property. Northam is one of 40 towns and villages in Southampton where we work.

How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours, depending on how many layers have to come out. A visit to Northam is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Before we arrive
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Run the fan after every shower
- Never fill a movement joint with mortar or grout
- Always have old sealant cut out, not covered
- Check ceilings under showers for marks
Leave the new joint to cure fully before it gets wet or moves: generally around 24 hours, or as long as we advise.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
Your questions about remedial sealant in Northam
Do you take on hotel work around Northam?
Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.
Do you work for landlords with property near Bitterne station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Can you reseal a split movement joint?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
Do you guarantee remedial jobs?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Are you insured?
Yes. We are fully insured.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
Where do you work from?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

What happens if it’s left?
Ripping out a bathroom isn’t generally needed. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. Homes in smaller places like Northam can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

Signs you need remedial sealant in Northam
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
These are the problems we’re asked about most:
- Over-sealed joints coming away
- Torn expansion joints
- Smears and lumps from a botched reseal
- A shower that leaks however often it’s resealed
Schools such as Bitterne Manor Primary School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
What your quote should include
- What happens if the job turns out different
- When the joint can take water or movement
- Who does the work, and how experienced they are
- How long the guarantee is
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Landlords and agents in Northam can book us as well as householders. Resealing between tenancies keeps a property looking cared for.

We don’t publish a price list, because jobs vary so much. The quote depends on:
