We work on leaking tray & enclosure joints, failed movement joints and mouldy bath & shower sealant, and common reasons people get in touch are caulk or the wrong sealant used in a wet area and leaks that keep coming back after resealing.
Homes around Old Windsor range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
Every job comes with a 12-month guarantee.

What we do, step by step
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes a few hours, depending on how many layers have to come out in most cases. In a smaller place like Old Windsor, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- 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.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Before we arrive
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Run the fan after every shower
- Report a tray that rocks or a worktop that lifts
- Get the cause of a repeat leak found before resealing
- Check ceilings under showers for marks
Watch the joint over the first few weeks, particularly where the original failure was caused by movement. Should anything change, call 0345 464 0079 or drop us an email.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.
Common questions in Old Windsor
Do you cover smaller places like Old Windsor?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Old Windsor for remedial sealant?
Yes. Our work covers London and the South East, and Old Windsor is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in.
Do you fix expansion and movement joints?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Why act early in Old Windsor
Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out, so the joint can be treated and resealed. In an older home around Old Windsor, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
Why us?
- Anti-fungal silicone where joints get wet
- Every job guaranteed for a year
- Experience in homes, commercial sites and hotels
- Any old sealant cut out fully, not covered over

What else we do in Old Windsor
Remedial sealant around Old Windsor
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Managing a site like King's Court First School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. In the older streets around St Luke, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Rented homes near Sunnymeads station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

DIY sealant or a professional job?
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.
If you do try it yourself, take your time over the 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.

Surface by surface
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.
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is usually part of the cause. Along with resealing, we’ll mention if the room needs better ventilation.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- A tray or bath that is cracked
- Tiles that have come away from the wall
- Movement from fittings that aren’t supported
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.
