Bathroom resealing in Longwick
Kitchens need the same care as bathrooms. The joint between worktop and wall, the edge of the sink and the bottom of the splashback get wet every single day, and water behind a laminate worktop can make it swell. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. We are often asked to deal with water getting behind the kitchen upstand and damp behind the bath or under the tray, across kitchen worktops & upstands, sinks & splashbacks and basins & vanity units.
In a smaller place like Longwick, 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.

When something else is needed
A few problems are outside what sealant work can do:
- A tray or bath that is cracked through
- Water getting in through the grout rather than the sealant
- A leaking waste, trap or valve

Longwick questions
Do you work for landlords with property near Monks Risborough station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Is Longwick within the area you cover?
Yes. Longwick is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Where are you based?
Mr Mastic is based in Crawley. We cover Longwick and the rest of Buckinghamshire, along with the rest of our area.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
How long before the new sealant can get wet?
Silicone is touch-dry quite quickly, but it takes longer to cure. Leave it around 24 hours before it gets wet, or follow the cure time we give you.
How long does it take to reseal a bath or shower?
That depends on the number of joints and the state of the old sealant. For most single baths or showers, allow a couple of hours.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

How we quote for bathroom resealing
Your quote is based on your job. We take into account:
- The product the joint needs
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
- Whether the work is at height
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- The address or postcode of the job
- Whether it’s a home or a business
- Photos by email, if that is easy
- If someone has resealed it before
Every job is quoted individually, so start by telling us what you need. Just phone 0345 464 0079 or email us with the details.
Why it’s worth doing now in Longwick
A clean new bead makes a room look cared for, which helps when a home is being let or put on the market. A smeared, uneven DIY bead does the opposite. Around Longwick, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

What bathroom resealing looks like in Longwick
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Owlswick Chapel, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Managing a site like Longwick Church of England Combined School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Monks Risborough station change hands often, and fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.

What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Parking around Longwick is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We protect the area and cut out all of the old sealant.
- Next, the joint is cleaned and any mould is treated.
- The joint is left to dry, and baths are filled with water first.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- We clear away and tell you when it can get wet, usually after around 24 hours.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any tricky access

Advice
How the job changes by surface
Kitchen worktops & upstands
Water behind a laminate worktop can make the edge swell. A continuous bead along the back keeps water out, as long as the worktop itself is firmly fixed.
Sinks & splashbacks
Next to the sink, the sealant has to cope with constant water, and a food-safe product where it’s needed. The bead is finished smooth so it wipes clean.
