Remedial sealant in Strand-on-the-Green, done properly
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. We work on leaking tray & enclosure joints, mouldy bath & shower sealant and failed movement joints, and people most often call us about floor or wall movement joints that have failed and kitchen joints letting water behind the worktop.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Strand-on-the-Green are no different.
Our work is backed for twelve months, in Strand-on-the-Green and everywhere else we cover.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Use a soft cloth, not a scourer, on silicone
- Never fill a movement joint with mortar or grout
- Report a tray that rocks or a worktop that lifts
- Never seal over old silicone
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, ring 0345 464 0079 or drop us an email.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
Remedial sealant around Strand-on-the-Green
There are hotels and other places to stay in and around Strand-on-the-Green. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. London’s water is hard, so limescale builds up on sealant, grout and fittings.
For an older house near a landmark such as St Paul's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Schools such as Strand-on-the-Green Infant and Nursery School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

When to call us in Strand-on-the-Green
Movement tears sealant that isn’t designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
Keep an eye out for these signs:
- Gaps opening along the back of the worktop
- Leaks that keep coming back after resealing
- A second bead peeling off the first
- Caulk or the wrong sealant used in a wet area
As a London address, Strand-on-the-Green can be tricky for parking: let us know about parking bays, permits or a driveway.

FAQs for Strand-on-the-Green
Could a tired shower seal in my Strand-on-the-Green flat affect the neighbours below?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Is parking an issue for remedial sealant in Strand-on-the-Green?
Parking in Strand-on-the-Green, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you cover Strand-on-the-Green?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, and that includes Strand-on-the-Green.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you when we finish.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Can I choose the sealant colour?
In most cases you can choose. We’ll explain which colours are available and agree one before we start.
Can you take off two layers of silicone?
Yes. We cut out all the layers and clean off the film, before resealing with a single bead.
What happens on the day
Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours for most joints, depending on how much old sealant has to come out, depending on the size of the job. In Strand-on-the-Green, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- 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
- Keep children and pets away from the work area
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can

- Water damage behind tiles that needs a tiler
- Older mastics that may need an asbestos check before removal
- A tray or worktop that needs refixing first
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

What affects the quote in Strand-on-the-Green
Call for a quick quote. The main things that affect it are:
- The amount of work
- Which sealant suits the joint
- How many areas need sealing
- Any working-time requirements on site
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
- A few pictures by email, if you can
- What’s wrong with the joints now

Leave it or put it right?
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. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Strand-on-the-Green.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
