How the job changes by surface
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed colour-matched to the worktop.
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. We strip it back so we can see the joint, then reseal neatly.
Remedial sealant for homes and businesses in Borough Green
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. We work on expansion joints, failed movement joints and leaking tray & enclosure joints, and common reasons people get in touch are gaps opening along the back of the worktop and products that weren’t meant for the joint.
Homes around Borough Green range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Quotes for remedial sealant in Borough Green
We quote each job individually. These are the things that affect it:
- Any working-time requirements on site
- Whether the work is at height
- The size of the job
- The number of rooms or windows
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
What we need to know
Photos by email are helpful but not essential. Please mention:
- How we’d reach the joints
- If it’s domestic, commercial or a hotel
- The address or postcode of the job
- Pictures of the joints, sent by email
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, ring 0345 464 0079 or email us.
Why deal with it now?
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. In an older home around Borough Green, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Remedial sealant around Borough Green
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For landlords with property near Borough Green & Wrotham station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For site and facilities teams at buildings such as Borough Green Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes. If you live in an older home near The Church of the Good Shepherd, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
When it is not the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Tiles that have come away from the wall
- A bath, tray or worktop that moves until it’s properly fixed
- 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 you book.
Surfaces we seal
- Mouldy bath & shower sealant
- Botched or over-sealed joints

FAQs for Borough Green
Is Borough Green within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Borough Green & Wrotham station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Can you strip sealant from an acrylic tray safely?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Where do you work from?
We work from Crawley. Our applicators cover Borough Green.
Can failed expansion joints be resealed?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Someone sealed over the old bead. Can you fix it?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
How the visit works
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours, depending on how many layers have to come out. Parking around Borough Green 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 look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
