Digswell Bathroom Resealing
Our applicators work in Digswell on bath, shower, basin, wet room, worktop and sink resealing. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- A joint torn by a bath that flexes
- Cracked, shrunken or lifting silicone
- Water escaping at the shower enclosure
How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes half a day or less for one room, longer when the kitchen is included in most cases. A visit to Digswell is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We tidy up and give you the cure time, usually around 24 hours.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints

How we handle bathroom resealing in Digswell
Kitchens need the same care as bathrooms. Worktop upstands, sink edges and splashback joints get wet every single day, and water that gets into the back edge of a worktop can swell the board. Kitchen joints get a sealant suited to kitchens, colour-matched where it shows. Common call-outs are for water escaping at the shower enclosure and a reseal done over the top of the old bead, across basins & vanity units, baths and sinks & splashbacks.
Homes around Digswell range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What else we do in Digswell
Why deal with it now?
Mould removers can fade the surface of a stained bead, but mould that has grown into the sealant tends to return. The lasting answer is to remove the bead and start again. Around Digswell, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

When to call us in Digswell
Plenty of failed sealant has been laid over the top of older sealant. Fresh silicone can’t grip the old bead underneath, so it peels, leaks and hides mould behind it.
Any of these means the joints need attention:
- Leaks into the floor or ceiling below
- Smears of silicone across the tiles
- Cracked, shrunken or lifting silicone
- A reseal done over the top of the old bead
In the older streets around Digswell Village Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Questions to ask before you book
- Who turns up on the day
- What the cure time is
- Is VAT in the price?
- Which sealant they’ll use, and why
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Never pick at the silicone with a blade
- Stick to a soft cloth and a mild cleaner
- Wipe up water along the back of the worktop
- Don’t let bottles sit on the bead
Mould needs damp, so keep the room aired. Use the fan, or open a window, while you bathe and for a while afterwards, so the bead dries out between uses.
Worktop joints fail quietly. Water gets behind the upstand and into the edge of a laminate worktop, and the board underneath can swell. A reseal in time can save the worktop.
Questions from Digswell
Is it worth replacing old sealant in an older home in Digswell?
Generally, yes, if it’s cracked, shrunk, mouldy or coming away. New sealant will not stick to old, so the old bead has to come out completely first.
Will you come out to Digswell?
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.
Where do you work from?
Mr Mastic is based in Crawley. We cover Digswell and the rest of Hertfordshire.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Can mouldy silicone be sorted out?
Yes. Once mould has grown into the silicone, it generally can’t be cleaned out for good, so we cut it out, treat the joint and reseal with anti-fungal silicone.
How the job changes by surface
Wet rooms
Not every wet room leak is a sealant problem. We reseal the joints and will tell you if the water seems to be coming from somewhere else.
Kitchen worktops & upstands
Kitchen joints need more degreasing than bathroom ones, because cooking grease stops sealant bonding. Proper degreasing is what helps the new joint last.
How we quote for bathroom resealing
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any working-time requirements on site
- The number and length of the joints
- Access and height
- Mould in or behind the old joints
The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before we start.
What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- The address or postcode of the job
- If someone has resealed it before
- Any access issues, like height or stairs
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, call 0345 464 0079 or drop us an email.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
