About our remedial sealant in Silchester
Water on the floor does not always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we will tell you rather than reseal something that won’t fix it. If you are dealing with worktop sealant that has shrunk and split and dark patches showing through the sealant, we can put it right.
In a village or hamlet like Silchester, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Whatever the size of the job, you get the same 12-month guarantee in Silchester and across West Berkshire.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Do not add new sealant on top of old
- Keep bleach and abrasives off the bead
- Keep the room well ventilated
- Keep an eye on the ceiling below the bathroom
Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
Do you need remedial sealant in Silchester?
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
If you can see any of these, it’s time to have the joints looked at:
- Decorators’ caulk around a bath or shower
- Thick, messy sealant smeared over tiles
- Kitchen joints letting water behind the worktop
- Sealant that came away because the surface wasn’t prepared
If you look after a building such as Silchester Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Before you book anyone
- What the cure time is
- What product goes in the joint
- How the surfaces are prepared before sealing
- What happens if they find a problem under the old sealant
When something else is needed
New sealant cannot fix everything, and we’ll tell you before we start. It will not solve:
- Movement from fittings that are not supported
- Failed tanking or loose tiles behind the sealant
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, phone 0345 464 0079 or email us and we will say what we think before booking.

I let a flat near Bramley (Hants) station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Can you work on commercial sites?

Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.

For anyone letting property in or around Silchester, several properties can go on one quote. Send us the addresses and the work at each.
Surface by surface
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom before resealing.
Silchester homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
If you let a flat or house near Bramley (Hants) station, a joint that keeps failing is best fixed properly while the property is empty. For an older house near a landmark such as Saint Luke's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

We bring what the job needs, so it can be finished in one trip where possible.
