Remedial sealant in Marsworth
Movement and expansion joints fail when the sealant cannot stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. We work on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints, and common reasons people get in touch are movement joints that have split or pulled away and decorators’ caulk around a bath or shower.
In a village or hamlet like Marsworth, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

How it works
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied, including the tidy-up. Somewhere as small as Marsworth, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
- Mention any parking rules near the property

Marsworth homes and their sealant
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.
Homes close to Church of All Saints include some older properties, and walls and floors in older homes can move, and sealant and grout show it first. Managing a site like Marsworth Church of England Infant School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Why deal with it now?
DIY removal often leaves scratches and a film of residue, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Older cottages and farmhouses around Marsworth can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Any old sealant cut out fully, not covered over
- Experience in homes, commercial sites and hotels

What we can’t put right

- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

What to tell us for a quote

- If someone has resealed it before

Do you need remedial sealant in Marsworth?
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Common reasons people contact us are:
- Gaps opening along the back of the worktop
- A shower that leaks however often it’s resealed
- Caulk or the wrong sealant used in a wet area
- Mould trapped under a layer of silicone
Rented homes near Tring station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Marsworth questions
Do you work for landlords with property near Tring 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 price.
Do you cover smaller places like Marsworth?
Yes. Marsworth is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
What if the leak isn’t the sealant?
We will tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, so we won’t pretend it will.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
