Remedial sealant in Hook, done properly
Two decades of sealant work means we recognise most failures quickly. We’re fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. We work on failed movement joints, botched or over-sealed joints and mouldy bath & shower sealant, and people most often call us about a shower that leaks however often it’s resealed and decorators’ caulk around a bath or shower.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Hook are no different.
Your job is guaranteed for a year, as with all our work.

How the job changes by surface
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We take care not to make it worse, and tell you about any damage we find.
Mouldy bath & shower sealant
Repeat mould usually points to a damp, poorly aired room. Along with resealing, we’ll mention if the room needs better ventilation.
Common problems we fix in Hook
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, and the joint starts to come away early.
Look out for any of the following:
- Products that weren’t meant for the joint
- Beads that never stuck properly
- Kitchen joints letting water behind the worktop
- Wide, uneven beads that look worse than the old ones
Letting a property close to Chessington North station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Before you book anyone
- What guarantee comes with the work
- When the joint can take water or movement
- Which colour the sealant will be
- Who turns up on the day
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Hook questions
Do you work for landlords with property near Chessington North station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Is parking an issue for remedial sealant in Hook?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
What if resealing won’t fix my leak?
That is why we look for the cause first. If the fault is elsewhere, you will know before any work is done.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
Can you strip sealant from an acrylic tray safely?
Yes. Careful removal is most of a remedial job, especially on acrylic, enamel and uPVC.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Hook, along with the rest of our area.
Do you guarantee remedial jobs?
Yes. Our one-year guarantee covers the work, and we’re fully insured.

How the visit works
On the day, we look over the joints with you first. Surfaces next to the work are protected before we start. Most jobs take a few hours, depending on how many layers have to come out. In a London area like Hook, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- Surrounding tiles, trays and frames are protected first.
- 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.
- You get the cure time and our view on why the joint failed.
How to prepare
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

Bathrooms and kitchens in Hook
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around St Paul's, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Hook is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
