Bathroom Resealing in Calvert
Problem with your baths, showers and worktops in Calvert? We remove the old material, prepare the joints and seal them properly.
- Water escaping at the shower enclosure
- Cracked, shrunken or lifting silicone
- Lumpy, uneven sealant from a DIY attempt
Bathroom resealing for homes and businesses in Calvert
Homes in Calvert have the same weak spots as anywhere else: the long edge of the bath, the base of the shower tray, the back of the basin and the line along the worktop. Each one is stripped, cleaned and dried before new silicone goes in. We’re often asked to deal with water getting behind the bath panel and water getting behind the kitchen upstand, across kitchen worktops & upstands, shower trays & enclosures and wet rooms.
In a village or hamlet like Calvert, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Look for lifting corners and small gaps now and then
- Wipe up water along the back of the worktop
- Never pick at the silicone with a blade
- Let new sealant cure fully before it gets wet
Keep water off the new bead until it has cured, which is normally around 24 hours. After that, a quick wipe after showering helps keep it clean.
Small signs come before a leak: lifting ends, gaps, dark shadows under the bead or a stain downstairs. If you spot one, it’s time to reseal.

Bathroom resealing around Calvert
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.
If you live in an older home near Church of St Michael, walls and floors in older homes can move, and sealant and grout show it first. Around Calvert, as everywhere, bathroom resealing is only as good as the preparation behind it.

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 couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. For a village or hamlet like Calvert, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at every joint first and check for movement or leaks.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- Joints are degreased and any mould is treated.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- We tool the bead to a neat finish and give you the cure time, generally around 24 hours.

What does bathroom resealing cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
Where is Mr Mastic based?
We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you get rid of the black mould in my sealant?
Yes, we replace the mouldy bead. Sprays can fade the marks, but cutting it out and resealing is what lasts. Good ventilation helps keep it away.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Surface by surface
Wet rooms
In a wet room, the joints between floor and walls take standing water. They’re resealed with anti-fungal sanitary silicone, and our work is on the visible joints only.
Kitchen worktops & upstands
Kitchen joints need more degreasing than bathroom ones, because cooking grease stops sealant bonding. The extra cleaning is what makes the bead last.
Quotes for bathroom resealing in Calvert
We quote each job individually. These are the things that affect it:
- Mould in or behind the old joints
- Access and height
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Pictures of the joints, sent by email
- Whether it has been sealed before
- How we’d reach the joints
- How many joints, rooms or windows are involved
Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Why it’s worth doing now in Calvert
A quick bead over the top of the old one might look better for a while, but it cannot stick to what’s underneath. Water creeps under it and mould follows, and the next reseal means two layers to cut out. In a small place like Calvert, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
