How we handle remedial sealant in Brighton
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. If you are dealing with thick, messy sealant smeared over tiles and sealant applied over old sealant that has lifted, we can put it right.
Alongside its houses and flats, Brighton has offices, shops and places to stay, and their washrooms and staff kitchens need the same attention as any home. The work is the same in both: old material out, joints cleaned and dried, and a fresh, even finish.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Windows & doors
Smeared or badly matched mastic can be cut out and redone neatly, matched to the frame colour.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Your questions about remedial sealant in Brighton
Do you work for landlords with property near London Road (Brighton) station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you work in hotels near Brighton?
Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
What remedial sealant looks like in Brighton
Brighton is within about 1 mile of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. 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 London Road (Brighton) station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. If you live in an older home near St Martin's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most joints, depending on how much old sealant has to come out. Jobs in a place the size of Brighton range from town-centre flats to offices and family homes. For each, it helps to know about access, parking and where the joints are.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Move anything stored near the joints
- Tell us if parking is tricky
- Keep children and pets away from the work area

Common problems we fix in Brighton
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
Keep an eye out for any of the following:
- Repeat leaks from the same joint
- Products that weren’t meant for the joint
- A second bead peeling off the first
- Movement joints that have split or pulled away
For site and facilities teams at buildings such as Fairlight 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.

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Use a soft cloth, not a scourer, on silicone
- Keep the room well ventilated
- Keep movement joints clear of mortar and paint
- Ask why a joint failed before redoing it
Clean gently: no scraping, scouring pads or harsh chemicals.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
What happens if it’s left?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. For businesses in Brighton, a room closed because of a leak or mould costs more than the sealant, so it pays to replace failing joints before they get that far.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
