How we handle remedial sealant in Marlow
Remedial jobs in Marlow normally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. We work on shrunken worktop sealant, leaking tray & enclosure joints and mouldy bath & shower sealant, and people most often call us about decorators’ caulk around a bath or shower and gaps opening along the back of the worktop.
Marlow mixes older houses with estates built more recently, and bathrooms range from decades-old suites to brand-new ones. Whatever their age, sealant and grout tend to go before anything else.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- A leaking trap, valve or supply pipe
- A bath, tray or worktop that moves until it’s properly fixed
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed

FAQs for Marlow
Can you help a landlord with a rental near Marlow station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you take on hotel work around Marlow?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Do you guarantee remedial jobs?
Yes. Remedial work carries the same 12-month guarantee as all our work.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Someone resealed my shower and it’s leaking again. Can you help?
Yes, generally. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Keeping the joints in good condition
Aftercare is simple:
- Find out why the sealant failed first
- Keep the room well ventilated
- Act on a lifting corner straight away
- Have loose fittings fixed before resealing
Keep the room ventilated: use the extractor or open a window after showering.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
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.
Why deal with it now?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Black mould and gaps in sealant do not fix themselves, and in a busy household in Marlow they spread with every shower and every downpour. Now is the easy time to put it right.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email.

Do you need remedial sealant in Marlow?
A lot of failed joints have been sealed over rather than replaced. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.
Any of these means the joints need attention:
- Caulk or the wrong sealant used in a wet area
- Floor or wall movement joints that have failed
- A shower that leaks however often it’s resealed
- Mould trapped under a layer of silicone
For an older house near a landmark such as Congregational Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours, depending on how many layers have to come out, including the tidy-up. For a job in Marlow, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- 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
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height
