Surface by surface
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We say so rather than reseal.
Windows & doors
A frame that keeps leaking may not be the mastic. We check the joint and tell you if it looks to be something else.
About our remedial sealant in Grain
A joint that keeps failing generally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. If you have torn expansion joints and decorators’ caulk around a bath or shower, we can help, on botched or over-sealed joints, mouldy bath & shower sealant and expansion joints alike.
Somewhere as small as Grain, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.

How the visit works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. Somewhere as small as Grain, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
Advice
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Don’t point over movement joints
- Ask why a joint failed before redoing it
- Always have old sealant cut out, not covered
- Deal with small splits early
Give the new sealant its full cure time: generally around 24 hours, or as long as we advise.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Grain homes and their sealant
Grain is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as St James Church of England Primary Academy, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near Sheerness-On-Sea station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Why act early in Grain
Adding more sealant is the usual quick fix, and it rarely works. It cannot bond to what’s underneath, leaving the leak in place and one more layer to cut out later. Where a wall is exposed, as many are in small places like Grain, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Signs you need remedial sealant in Grain
A lot of failed joints have been sealed over rather than replaced. New silicone can’t stick to the old bead, so the top layer lifts and water and mould collect between the two.
People usually contact us after spotting something like this:
- Floor or wall movement joints that have failed
- A shower that leaks however often it’s resealed
- Gaps opening along the back of the worktop
- Sealant that came away because the surface wasn’t prepared
In the older streets around Church of St James, walls and floors in older homes can move, and sealant and grout show it first.

For landlords and businesses
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Grain: your questions answered
Is Grain within the area you cover?
Yes. Grain is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Grain in your area for remedial sealant?
Yes. We work across London and the South East, and Grain is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What happens if the problem is the tray or the plumbing?
We’ll tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, so we will not pretend it will.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
