How we handle remedial sealant in Runwell
A joint that keeps letting you down needs more than another bead. It helps to have pictures when you phone 0345 464 0079 or email us, along with when it was last resealed. We work on expansion joints, shrunken worktop sealant and mouldy bath & shower sealant, and the jobs we see most are repeat leaks from the same joint and smears and lumps from a botched reseal.
Even in a smaller place like Runwell, bathrooms and kitchens see heavy daily use. Older or newer, every room gets the same approach: all the old material out, the joint cleaned and dried, then new sealant or grout.
Big or small, it’s backed by our one-year guarantee.

What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours, depending on how many layers have to come out. Parking around Runwell is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- Let us know about earlier repairs to the joints

Advice
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Plumbing leaks behind walls or under trays
- Movement from fittings that aren’t supported
- Cracks in the fitting rather than the joint
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

What affects the cost of remedial sealant
There’s no set price list, because no two jobs are the same. What we look at:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- The number and length of the joints
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- If someone has resealed it before
- Where the job is, and your postcode
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
How the job changes by surface
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal.
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.
Signs you need remedial sealant in Runwell
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
Signs it’s time to call us include:
- Thick, messy sealant smeared over tiles
- Caulk or the wrong sealant used in a wet area
- Movement joints that have split or pulled away
- Gaps opening along the back of the worktop
In the older streets around Church of St Mary, older homes can move a little, which is hard on rigid grout and tired sealant.

Why it’s worth doing now in Runwell
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. Homes in smaller places like Runwell can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Report a tray that rocks or a worktop that lifts
- Keep the room well ventilated
- Ask why a joint failed before redoing it
- Check ceilings under showers for marks
Don’t let anyone seal over it later. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.
Runwell: your questions answered
Will you come out to Runwell?
Yes, Runwell is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do remedial sealant in Runwell?
Yes. We work across London and the South East, and Runwell is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Can you remove old sealant without damaging the bath?
Yes. Residue is removed with a product suited to the surface rather than scraped hard, so the new sealant bonds cleanly.
What if resealing won’t fix my leak?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Runwell, along with the rest of our area.
My shower still leaks after a reseal. Can you sort it?
Yes. Repeat leaks usually come from over-sealing, movement or water getting in elsewhere, and we deal with the cause first.
Does remedial work come with a guarantee?
Yes, with our 12-month guarantee. Where we have flagged another fault, it needs fixing for the joint to last.
Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Remedial sealant in Runwell: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as Runwell Community Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For landlords with property near Wickford station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
