About our remedial sealant in Merstham
Movement and expansion joints fail when the sealant can’t stretch. 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 mouldy bath & shower sealant, expansion joints and failed movement joints, and the jobs we see most are mould trapped under a layer of silicone and kitchen joints letting water behind the worktop.
Somewhere as small as Merstham, 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.
Whatever the size of the job, you get the same 12-month guarantee in Merstham and across Surrey.

Remedial sealant around Merstham
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
If you look after a building such as Merstham Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Merstham station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. In the older streets around Church of St Katharine, walls and floors in older homes can move, and sealant and grout show it first.

How it works
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied from start to finish. For a village or hamlet like Merstham, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- Try not to wet indoor joints just before the visit

Common questions in Merstham
Can you do remedial sealant in Merstham?
Yes, Merstham is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Will you come out to Merstham?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I choose the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before any work starts.
Does remedial work come with a guarantee?
Yes, for 12 months. If we have pointed out another problem, getting it fixed helps the new joint last.
Can you reseal a split movement joint?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
What happens if the problem is the tray or the plumbing?
In that case, we tell you what we have found. You may need a plumber or bathroom fitter.
How long will it take to strip and reseal the joint?
That depends on how many layers there are and how many joints. We will tell you before any work starts.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
What happens if it’s left?
Another bead over the top won’t fix a failed joint. It does not grip the old layer, so the leak carries on and there’s now more to remove. Where a wall is exposed, as many are in small places like Merstham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Quotes for remedial sealant in Merstham
For a quick quote, just ask. What matters most is:
- The type of sealant required
- Any working-time requirements on site
- The number and length of the joints
- Whether old sealant or filler has to be cut out
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Pictures of the joints, sent by email
- Roughly how big the job is
- Where the job is, and your postcode
- Whether it has been sealed before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, phone 0345 464 0079 or email us.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Always have old sealant cut out, not covered
- Never fill a movement joint with mortar or grout
- Act on a lifting corner right away
- Keep bleach and abrasives off the bead
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
