About our remedial sealant in Whitehouse
The wrong product in the wrong joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. Typical jobs include floor or wall movement joints that have failed and repeat leaks from the same joint, on mouldy bath & shower sealant, botched or over-sealed joints and expansion joints.
In and around Whitehouse, older properties sit alongside newer ones. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
Big or small, you get the same 12-month guarantee.

Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
FAQs for Whitehouse
Will you come out to Whitehouse?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Whitehouse and the rest of Milton Keynes, along with the rest of our area.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What does remedial sealant cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look for stains below bathrooms now and then
- Use a soft cloth, not a scourer, on silicone
- Air the bathroom so the sealant can dry
- Get the cause of a repeat leak found before resealing
Leave the new joint to cure fully before it gets wet or moves: generally around 24 hours, or as long as we advise.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Each one is worth getting looked at.
Whitehouse homes and their sealant
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 let a flat or house near Milton Keynes Central station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. If you look after a building such as Whitehouse Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

What we do, step by step
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most joints, depending on how much old sealant has to come out in most cases. Parking around Whitehouse is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions

Honest limits
New sealant can’t fix everything, and we’ll tell you before work begins. It won’t solve:
- A bath, tray or worktop that moves until it’s properly fixed
- A cracked shower tray or bath (that needs repair or replacing)
- Water damage behind tiles that needs a tiler
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Leaking tray & enclosure joints
- Expansion joints
- Botched or over-sealed joints
- Failed movement joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
Do you need remedial sealant in Whitehouse?
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
Common reasons people contact us include:
- Floor or wall movement joints that have failed
- Gaps opening along the back of the worktop
- Mould trapped under a layer of silicone
- Smears and lumps from a botched reseal
In the older streets around Church of the Holy Cross, older homes can move a little, which is hard on rigid grout and tired sealant.

What the job involves on each surface
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal colour-matched to the worktop.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
