Remedial sealant for homes and businesses in Gawcott
A joint that keeps failing generally has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. We work on failed movement joints, leaking tray & enclosure joints and shrunken worktop sealant, and people most often call us about dark patches showing through the sealant and smears and lumps from a botched reseal.
Homes around Gawcott are mostly houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Do you need remedial sealant in Gawcott?
How a joint is built matters as much as the product. Sealant packed too deep, or stuck to the back of the joint as well as the sides, can’t stretch, so it tears when the joint moves. Backing sets the depth and stops that.
Any of these means the joints need attention:
- Beads that never stuck properly
- Sealant applied over old sealant that has lifted
- Floor or wall movement joints that have failed
- A shower that leaks however often it’s resealed
Managing a site like Roundwood Primary School? Then 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.

Why it’s worth doing now in Gawcott
Mould under a bead cannot be reached by cleaning. The layers have to come out, so the joint can be treated and resealed. Older cottages and farmhouses around Gawcott can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

What the job involves on each surface
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath, then reseal neatly.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out so the new sealant starts clean.
FAQs for Gawcott
Is remedial sealant in Gawcott guaranteed?
All our work, in Gawcott and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you do remedial sealant in Gawcott?
Yes. Our work covers London and the South East, and Gawcott is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Can failed expansion joints be resealed?
Yes. Where mortar or filler has been used instead of sealant, it’s removed where it can be, and reseal with a flexible product.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Can you take off two layers of silicone?
Yes. Both layers come out; over-sealing fails because silicone will not bond to silicone.
Gawcott homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Church of Holy Trinity, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Looking after it afterwards
Aftercare is simple:
- Run the fan after every shower
- Report a tray that rocks or a worktop that lifts
- Don’t add new sealant on top of old
- Clean sealant with mild products only
Give the new sealant its full cure time: follow the cure time we give you.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.
How it works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours, depending on how many layers have to come out for a typical job. For a village or hamlet like Gawcott, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
