- Over-sealed joints coming away
What happens on the day
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. A visit to Clewer is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we find out how and where the joint has failed.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Before we arrive
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints

How we handle remedial sealant in Clewer
A joint that keeps letting you down needs more than another bead. Send pictures when you phone 0345 464 0079 or email us. If you’re dealing with kitchen joints letting water behind the worktop and a shower that leaks however often it’s resealed, we can help.
In a smaller place like Clewer, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
You get a one-year guarantee, the same in Clewer as everywhere else we work.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep movement joints clear of mortar and paint
- Keep an eye on the ceiling below the bathroom
- Report a tray that rocks or a worktop that lifts
- Keep the room well ventilated
Clean gently: a mild cleaner and a soft cloth, with no blades or scourers.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
What else we do in Clewer
When to call us in Clewer
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. Then the only fix is removal and a new bead.
The most common problems we see are:
- Dark patches showing through the sealant
- Smears and lumps from a botched reseal
- Leaks that keep coming back after resealing
- Gaps opening along the back of the worktop
Letting a property close to Windsor & Eton Central station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Different surfaces, different methods
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Landlord and commercial work in Clewer
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

Common questions in Clewer
Can you help a landlord with a rental near Windsor & Eton Central station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Is Clewer within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you remove old sealant without damaging the bath?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
Can you take off two layers of silicone?
Yes. Each layer is cut out and the residue cleaned off, before resealing with a single bead.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
What does remedial sealant cost?
Size, access and the old material all affect the cost. Call for a quick quote.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Do you fix expansion and movement joints?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
What remedial sealant looks like in Clewer
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Clewer has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Schools such as St Edward's Catholic First School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you live in an older home near Church of St Andrew, older homes can move a little, which is hard on rigid grout and tired sealant.
